manufacture of rings of concrete technology
To a home septic tank had served for many years to do his best not to brick and of concrete rings. Buy them is not difficult, but also to make their own do not have to be a great professional.
The cost is cheaper, and the cesspool do not have to fit a standard size when the designer himself can choose any convenient.
Concrete collars provide an opportunity to the most simple and expeditious way to arrange items of the independent water drain on a country site
Of concrete rings quickly and quite simply collect cesspools to overflow, carrying out the primary processing of waste water
Concrete and concrete rings are used in the construction of manholes with filtering bottom, which is made through utilization of treated waste water into the soil
Concrete and reinforced ring assembly suitable for any complexity cesspools, sewage treatment plants with any number of chambers
Cumulative cesspool of concrete rings
Two-chamber septic tank with overflow
The filter pit made of concrete rings
Three-chamber sewage system
Getting to the implementation of the conceived need, first of all, decide on the place - choose a fairly large and flat area. Concrete mix will have to prepare a lot, so you need a cement mixer.
Since the product is badly, as they move not do without lifting devices. Forming rings need a special form.
Contents sump with concrete rings - a good solution. This beneficial financially option is easy to implement on your own site any owner who owns a minimum of skills in the construction
For the production of rings
Form rings has a simple geometry: a pair of cylinders - internal and external. Difference between the diameters should be equal to the wall thickness, which is about 1.5-2 cm.
You can get them in different ways. The most simple - buy the factory product with an internal cone-shaped core and an outer ring, strengthening ribs and installed on it a vibrator.
A suitable material for the shape of a galvanized iron. For the stability of the form of draped wet sand and tamped it, or lightly pressed into the ground formwork
After installation of this form on a flat pad in her laying reinforcement and pour its solution. Shrinkage mixture on each fill step provides a vibrator. This prevents the formation of air voids in the concrete walls of the body. Reinforcement - operation is not mandatory, but desirable, as the product is getting harder.
Even simpler - take two drums with suitable parameters or pipe. It can be manufactured from sheet metal cylinders. Sheets of interconnected canopies - door or window. The most accessible way - the production of forms with planed boards.
The most simple and efficient way to manufacture autographic concrete rings linked to rent or purchase the prefabricated metal mold
Formwork for individual processing can be made of sheet steel 4.3 mm thick. As the thrust and rigid couplings are used fittings
In the manufacture of self-made forms it uses a thin steel roofing thickness up to 1 mm. In this case, it strengthens the board as a support frame
Convenient for work on pouring the formwork will be a rack connected to the metal strip. For the isolation of this embodiment is used a polyethylene outer sheath
Form filling plant production
Self-made metal formwork
The shape of the thin tin and boards
Form rings from the rack with polyethylene
Production of form boards
To produce such a shape required board thickness of 2 to 5 cm. The outer and inner cylinders made collapsible, consisting of several wooden rings. On wheels for stuffed inside the outer cylinder is well treated boards.
The inner cylinder should also be assembled and disassembled easily. Make it the same rules as the outer portion of the mold, but not sheathe the inner and the outer diameter. After the mold assembly between the cylinder should remain a gap of 1.5-2 cm.
For articles relevant parameters need to compute the dimensions of the mold. Assume for the sump need diameter ring 840 with a wall thickness of 140 mm and 890 mm. To calculate the internal diameter using the formula: Dv.n. = D + 2h, where D = 840 mm, h = 20 mm (thickness of lining board).
These values are substituted into the formula: Dv.n. = 840 + 2 x 20 = 880 mm. If we assume the width of 100 mm diameter of the rings of the ring outdoor areas Dn.n. = Dn.v. + 2S = 2 x 880 + 100 = 1080 mm.
Given that the need to make a ring with a wall thickness of 140 mm, an outer diameter of the wood core is: Dn.v. = D - 2B - 2h. Where D - diameter of the product, B - the thickness of the finished rings, h - the thickness of the board. Dn.v. = 840 - 2 x 140 - 2 x 20 = 520 mm.
In order to mark the ring is placed on flat ground a wooden board with a nail driven into his heart. Make improvised compass: to nail tied the cord and the other end of the latter - a pencil with which markup and perform.
If manufactured formwork inner wall of the ring width is also equal to 100 mm, the core must have an inner diameter Dv.v. = Dn.v. - 2S = 520 - 2 x 100 = 320 mm.
Express User pouring rings
The process of making concrete rings with filling solution in the formwork made of boards, the steps to submit the following photo-selection:
For precise geometry rings initially produce boards of two belts 150h35 mm. The diameter of both circles 980 mm
Form for pouring concrete rings collect from the small decking 110h22 mm. We make two separate half-cylinder, as the form must be split
From the outside oboshem both halves of galvanized sheet metal cylinder. External oboshem half-cylinders on the inside
Inside the casing fix two spacers boards made from scraps of lumber. They provide stiffness during concrete curing, and then extracts the first, to facilitate the separation of the form
Before pouring the solution on the metal surface is applied TAP 15 gear oil brands
To fill choose a flat area, it was covered with polyethylene, install half cylinders and collect the form. If you are planning to do w / w rings set inside a mesh
To two formwork were equidistant from each other and ensure the formation of an equal thickness of walls, set the anchor or metal rods with screws. To make it easier to remove them after the initial curing, use plastic covers
On the inner cylinder put some sort of pedestal - made of planks round table. It is needed for the uniform distribution of the solution
Step 1: Production of the semi-circular zones
Step 2: Assembling two half molds for casting
Step 3: Boarding the outside of the tin
Step 4: Install the two spacers doskok
Step 5: Application of lubricant on the surface of the formwork
Step 6: Build a removable formwork before pouring
Step 7: Fixing the formwork metal rods
Step 8: Install the table on the inside of the casing
These steps are in fact preparing to work on the casting. Now you're ready to direct the production of concrete rings:
The first mixer load cement with sand in the selected predetermined ratio. After stirring, pour the water. We count on 5 buckets solution
Unload the prepared mixture on the table. Gently and evenly distribute it in the formwork
Fill the formwork in layers, trying to quickly run to the top of the previous layer had no time to "grab" between the layers and not turned the border
Each layer is compacted to prevent formation of air bubbles, reduce the strength of the product. It is advisable to stock up vibrouplotnitelej if it is not, you will have to act with a shovel or a scrap rebar
The end section of the cast concrete into the formwork rings aligned trowel. Top close the polythene and leave for at least 3 days, it is better for 14 days
Waiting for curing concrete in the formwork solution, remove it. We make the same operation for the production of the new ring
We produce ring device sump in the required amount. Advance forward in terms of the number of drains 3 days
Divide the device space for the sump. Roy pit and set ring preliminary treatment of the outer part bitumastic
Step 9: Preparation of concrete solution
Step 10: Discharge the resulting mixture on a table
Step 11: Layered filling formwork solution
Step 12: The vibration compaction tool solution
Step 13: Preparation of the cast rings of solidifying
Step 14: Remove the formwork after solidification
Step 15: The blank rings in the required amount
Step 16: The breakdown of seats for the construction of raking
Manufacture from reinforcement belt
You need to prepare round ribbed rolled thickness of 0.8-1 cm, from which the knit reinforcement ring.
Ring, the number of which depends on the height of the articles to be interconnected vertically, using reinforcement sections. It is desirable to maintain a distance between the reinforcing zones approximately 25 cm. Between the sections reinforcement, mounted vertically, it is recommended to comply with a step of 35 cm.
Reinforcement elements can be fixed by welding, but a more reliable construction is obtained when the binding rods. The metal should be at least 3.5 cm from the edge of the concrete
For the convenience of transporting the finished product up armirovochnogo frame tied the workpiece in the form of loops of wire. Can be used and the stainless steel grid with a minimum thickness for the reinforcing cage 0, 4 cm. A ring formed therefrom and fixed by means of the wire edge.
Pouring concrete mix
To begin the manufacture of the rings can be at a temperature of not lower than 8 and not greater than 22 ° C. formwork elements are inserted into each other after coating them with machine oil - is subsequently facilitate their dismantling. The gap between the cylinders of the carcass reinforcement is inserted.
In order to give stability armature, it is fixed by means of wedges. Subsequently, the wedges are removed as the concrete form filling mixture.
A solution of observing the following proportions:
- Fresh cement not lower M400 - 1 piece.
- Crushed granite or limestone with malookatannymi grain size of not more than 0, 2 cm - from 4 to 5 parts.
- Quartz sand grains with a size of at most 0.22 cm - from 2 to 3 parts.
- Water - a maximum of 0.7% by weight of cement.
Experts have their own secrets of preparation of the concrete mixture. Sometimes they add to it potassium glass in order to increase the plasticity of the mass and vodopronepronitsaemost. To castle, the composition has increased, it is administered in a component such as PVA adhesive. Fluidity of the mixture is increased by adding detergent.
It is important to immediately consume ready-mixed concrete, because it is better to calculate the right amount for a potting mix.
It is important to be aware of such a parameter as the water-cement ratio. With its increasing rigidity mixture decreases, which reduces the complexity of mold filling, but also reduced strength indicators
Stiffness to the eye can be determined by placing the mixture on a horizontal plane. If the slope it will drain quickly, the mixture is very liquid. On average ductility of the mixture indicates its slow drift.
When the mixture is stuck and does not slip, so it is a little plastic, and if the mass does not even change its shape and lay a lump, it shows its rigidity.
To navigate in this matter, as the selection of the number of components required for the preparation of 1 mᶾ concrete, you can use this table.
|grade solution||Cement M 400 (kg)||Rubble (kg)||Sand (kg)||Water (l)|
Since rings cesspool - reinforced construction, there is more suitable for a small concrete hardness. When using Portland cement M500, M400 standards for multiplied by 0.88. For other brands are taking and other factors.
Preparing a mixture of a consistency resembling a stiff dough, is sent to the first formwork layer thickness of about 10 cm. The skip is then performed: taking a steel rod 20 mm in diameter and carefully compacted material.
In this manner, fill the entire volume between the two cylinders. When you are finished, close the product out of direct sunlight, throwing on top of a piece of thick fabric.
Remove the formwork for the incident 14 days left in the same place more days at 4, not forgetting periodically watered. If the filling is performed less dense mixture, then the process is called casting. Formwork from articles obtained by the second method, is removed in a week.
On the surface will sink and fill with cement mortar. The products manufactured by the second method, is formed smaller shells. Oil, which covered the surface of the cylinder is removed. Tighter connection ring provides a lock.
To obtain this element is added to form another ring 2, a Shared mounting chamfer forming a projection on one article and the neck on the other. This will allow firmly fix the ring during installation, preventing them from shifting.
A method for manufacturing rings, eliminating from the process laborious operation such as transportation of the finished product. For this form of rings are made on the spot, where he subsequently suggested digging a cesspool. First molded ring, and then the ground underneath is selected and gradually lowered to the bottom of it, by immersing in a hole completely.
When the upper edge of the product will be on the same level with the ground on it constructing a new formwork. Do the following ring and again choose the ground as long as the product edge is flush with the ground. Continue to make new rings until the desired depth of the sump.
Forms prefabrication possible to obtain high-quality products, but for the production of several rings sump acquire them irrationally
The most high-quality products are obtained, if it is possible to use a block-making technology, involves the installation of a special form on the vibration plate with a drive.
Stove executes oscillatory movements of small amplitude and high frequency that maximizes the compacted concrete mass.
His hands can produce w / w and the concrete rings of different diameters. In particular, the apparatus and the neck ring for manhole
Reinforcement of concrete rings can reduce product wall thickness of up to 8 cm (in the concrete is not less than 12 cm), and equip it with mounting lugs
Installation work is greatly facilitated if the rings at the ends to form a chamfer. For this purpose, the bottom formwork before casting and the upper end of the appropriate size after the stacked rings
If there are concerns about the accuracy of manufacture of the round in terms of the Rings, no one forbids them to do with a square cross-section

The use of plastic rings
Advantages of plastic rings for cesspool in their low weight, durability and ease of installation. For their production the raw material is low density polyethylene, which is characterized by excellent strength characteristics.
The most common size - height 150 cm, diameter of about 95 cm, a wall thickness of 25 cm.
Rings made of plastic provide a complete seal sump. Exclude leakage of untreated liquid waste into the ground through the side walls
Ring without harm to its integrity perceives high mechanical loads due to the ribbed body. For a single sump, as a rule, does not require more than 3-4 ring performing the function of the walls.
For the bottom and top of the sump use other parts: the bottom hatch ring to frame openings serving for connection to a sewage system.
If we compare the plastic rings with concrete, then, in addition to low weight, one can see a number of other advantages first:
- Quick installation using existing locking systems.
- Ease of disassembly.
- Fully sealed.
- Ability to perform a replace a failed ring.
- Lack of response to exposure to moisture. Plastic never razmoknet and will not corrode.
- On the plastic does not affect any aggressive chemicals or waste products found in the waste and soil bacteria.
- Smoother inner surface, not conducive to accumulation of plaque on it.
Lightweight construction can sometimes cause it to move under the influence of groundwater. To this did not happen by pouring the bottom of the pit, a special metal hooks inserted into the concrete floor. Through these devices reliably fix light plastic ring.
And how to spend waterproofing septic tank plastic insert can be found in this material.
Sometimes, the first ring is lowered into the sump at an even screed uncured. This is much easier than to fix it with hooks and ropes. There is in this negative side - will have to make great efforts in the case, if necessary dismantling construction.
Deciding to make a cesspool of plastic rings, it is necessary to define the place for her.
Health rules concerning the location of any septic tank, the same:
- at least 5 meters from the front door of the house and windows;
- not less than 3 m from the road and the landmark with the adjacent portion;
- 15 m or more from a well or wells with potable water;
- having access to work assenizatorskaya machines;
- the absence of a pit next to the fruit trees.
The next step - defining the scope. Shall be based on the daily consumption of water for 1 person living in the house. The common rate - 200 l. Digging a trench, satisfied at the bottom of the concrete screed 200 mm high, strictly controlling horizontality.
The process of installation of plastic rings consists of several steps: prepare the place dug a pit prepare bottom sequentially stacking sand, gravel, geotextiles, then perform direct mounting plastic products
Between the walls of the excavated pit and corrugated rings surface should be a gap of at least 30 mm. From the bottom and left 20 cm margin. If the bottom sump not plan concrete, this parameter is increased to 0.5 m.
When the latter option is selected, the device must filter layer composed of gravel and sand, separated by their inability to mix, geotextile. In the manufacture of plastic rings in their design has been laid in the form of insulation prodolnopoloy layer, but if in your area there are severe frosts in winter, and it is useful to further insulation.
For device insulation layer is necessary to take the cloth reflective material dimensioned such that the entire surface of the pit was covered after the lowering of the Rings. A material with reflective layer will not allow to leave the heat in the soil. Its edges are fixed on the perimeter of the top of the pit string.
The rings are immersed alternately using ropes. To each of them apply a little effort to connect with the previous. To do this, the design of grooves are provided.
The cable with which the immersed ring, tied at one end to a metal hook walled up the formwork, and the other throws on the opposite side of the hole and is fixed there. Received additional strengthening rings.
Now you can begin to backfill the tank. Typically, the outer side of the rings poured ground. But if the water table is high, the gap between the container and the excavation is placed a mixture of cement and sand in the ratio 1: 1.
Simultaneously with this operation in the capacity necessary to pour the water, making sure to pour a level below ground water level was 200 mm. If you do not, on the plastic under pressure created by the soil can cause cracks.
It remains to cover the hole sealed hatch, Which prevents the sump from getting into the rainwater. Furthermore hatch diameter 0.7 m, it is necessary to install the vent pipe with a cross section of 100 mm, which will be withdrawn from the well gases.
Plastic rings dock mainly by means of special slots provided design, but sometimes using welding and sealants
You can buy a special tool for purification of sewage, comprising live bacteriaFeeding organic and processing it to a liquid state. When the sump is not the bottom, most of its contents will go into the ground. In a closed sump collects more waste, so it has to be pumped out frequently.
