Many people now pay great attention to life problems, and of course, there are many key points in life. If you pay attention to them one by one, it will consume a lot of time, not to mention effort. Therefore, if you want to pay attention to one of them, you must also distinguish it first. You can have a look at what you are interested in. If you are not interested, don't look at it. What about the installation method of three compartment integrated septic tank in rural toilets? How to use FRP septic tank?
How to install the three compartment integrated septic tank in rural toilets?
Positioning money → Excavation of foundation pit (foundation pit drainage) → Bedding foundation → Septic tank in place → Fill the septic tank with water → Backfill and tamp symmetrically in layers → Connect the vent pipe → Masonry manhole → check before acceptance. The positioning, burial depth, inlet and outlet pipe ends and inspection wells of the integrated FRP septic tank shall be determined according to the design requirements. The bearing capacity of the foundation should not be less than 100kN / m2, otherwise the foundation treatment should be carried out, and the specific measures should be determined by the designer.
After the foundation pit is excavated to the predetermined elevation (the old soil layer shall not be disturbed), the underlying layer of the foundation pit shall be leveled when there is no groundwater, and then 150mm thick medium and coarse sand cushion shall be paved on it as the foundation of the septic tank. When there is groundwater or excavation, sand and gravel or gravel with a particle size of no more than 40mm shall be used for backfilling, with a compactness of ≥ 95％。 In case of poor soil quality, cast-in-situ reinforced concrete foundation is suitable. After calculation, the drainage measures taken during excavation of foundation pit are determined.

l. The selection of FRP septic tank is based on different buildings, and the design parameters are calculated by single project designers.
2. The location of FRP septic tank shall be set in principle so as not to affect the building foundation; Generally, the distance from the domestic and drinking water tank shall not be less than 10m. The distance from the underground water intake structure shall not be less than 30m. When the foundation plane of the building is higher than the foundation plane of the septic tank, the distance from the outer wall of the septic tank shall not be less than 2m When the foundation plane of the building is lower than that of the septic tank, the clear distance between the outer wall of the septic tank and the outer wall of the building should not be less than 5m.
3. The overall FRP septic tank is also covered with soil of 0.3m. The soil should not be more than 3m. In cold areas, when the temperature is lower than - 10 ℃, the soil covering depth of the septic tank shall not be less than l2m In areas where the average temperature in cold months is less than - 13 ℃, when designers consider the setting depth of FRP septic tank, it is appropriate that the sleep of FRP septic tank should be set below the freezing line in the area.
4. The FRP septic tank should be installed under the green belt, lawn and sidewalk, and the covering soil should not be more than 1.5m; It can also be installed in road sections.
5. Manhole cover: when the vehicle is not available, the light double-layer manhole cover and cover seat with lock shall be adopted; When passing the car, the heavy double-layer lock is adopted. The fiberglass septic tank also takes into account the needs of greening in the community or paving in the road square. The cast iron or polymer well cover is level with the ground. At the paved ground, the well cover can be appropriately lowered to below the paved floor brick. When the paved floor brick on the well cover must be opened when it is necessary to open the well cover.
The above content mainly describes the installation method of the three compartment integrated septic tank of the rural toilet? How to use fiberglass septic tanks? Septic tanks in rural toilets are particularly important. Of course, the difficulty of installing septic tanks is not too high. The main focus is on some items. Therefore, if you want to understand these, you must first investigate the parts clearly, and then you can master the installation methods.
