Today, construction markets offer many options for devices used in plumbing. Among these systems, plastic sumps are popular. What are these constructions? Consider their advantages and disadvantages, as well as the method of installation.
Storage tanks for waste
Plastic containers are quite popular, since they have a number of advantages, among which are the following:
If the mold is squeezed with soil
Does it have cesspools from plastic any flaws? Yes, but in general they are not very serious:
Instead of cables attached to a slab of concrete, you can use "anchors" - a special design that represents cables with weights that will not allow the pit to rise to the top.
They are not difficult to install
If the weight of the sump capacity of not more than 250 kg, a group of people consisting of about 5 workers will be able to easily carry out the entire process of mounting the product. What is the beginning of the installation?
First, it is necessary to determine the location on the summer cottage or the territory of a country house. Best of all, if the pit will be located close to the road, so that it is easier to pump it out with the help of a vacuum truck.
If you install the pit too far from the nearest porous scavenger entrance, you may encounter a number of problems. For example, in the nightman, the hose length to the pit may not be enough, and if it also leaks, then puddles of sewage may remain in the yard.
When we decided on the location, it is necessary to understand how deep the groundwater flows. After that, it is worth knowing the depth of soil freezing in the area where the sanitary system will be installed. This can be done by referring to the GOST tables or by asking those who have already carried out a successful laying of communications on the street.
By the size of the pit they dig a pit. You can dig it manually or using construction equipment. The second option is easier, easier and faster, but more expensive. When the foundation pit is ready, a base of concrete with a thickness of about 20 cm is made at its bottom, in which loops are made, so that cables are subsequently fastened to them. You can also lay a concrete slab on the bottom - however, in this case, the length and width of the pit may increase slightly. Concrete construction will not allow to land on the ground under a plastic pit.
The next step is to lower the tank. To do this, put it on the edge of the pit, tied with ropes and gently, slowly, lowered down and expose. The dimensions of the pit should be 55–60 cm larger than the pit.
The remaining space between the walls of the cesspool and the walls of the pit is covered with loose earth or sand. If water is not poured into the container before this process starts, the soil that is poured in can crush the product, and the cracks that appear will not be repaired. How much water should I pour? Its level should be higher than the top of the bedded soil by 20 cm.
At the end, rings are set, then finally level the surface of the soil around the plastic pit.
Pumping of a cesspool
If you observe during installation a few simple rules, we can guarantee the successful completion of work and high-quality work of the cesspool during its further operation.
So, setting the slab under the pit or pouring the concrete structure, you must adhere to the horizontal level. The distance between the walls of the pit and the plastic pit should be about 30 cm on all sides, at least 25 cm.
In addition to the aforementioned fiberglass, the walls can be reinforced with brickwork - in this case, a distance of 30 cm should be from the plastic container to the brick . A low-quality brick will be suitable for a masonry device; it is not necessary to plaster it - it will not allow the ground to crush the walls.
If ground water flows nearby, then instead of sand or soil, it is recommended to use a dry mix of cement and sand in a proportion of 1 * 4.
If the pit is deepened in the ground by 0.5 m and more, then it is necessary to think out for it a reinforced concrete floor. Also, do not forget about the ventilation of the pit.
Over time, it is necessary to remove accumulated domestic waste water, and all work must be carried out in a timely manner and periodically. To do this, it is necessary to call a vacuum truck once a month. And to remove the smell in the pit, you can add special bacteria that turn thick sludge into a liquid mixture to make it easier to pump.
