The installation steps of FRP septic tank are as follows: I: according to the size (length, width and height) of the septic tank, dig the corresponding size of the foundation trench
The length and width of the foundation trench can be more than 30 cm around the tank to facilitate installation and commissioning
The backfilling fine sand and fine stone can be in place at the bottom of the tank to enhance the pressure resistance)
The elevation of the foundation trench is based on the bottom of the pipe orifice of the sewage inlet pipe on the construction site
The excavation depth: the height from the bottom of the pipe orifice of the inlet and outlet pipe on the tank to the bottom of the tank, Add 20-25cm fine sand cushion height, which is the total depth of excavation
Or: (take the tank diameter height minus 20 cm as the excavation depth, including the depth of 15-20 cm of sand cushion layer) II
Dig the foundation trench and level the bottom
In case of natural solid soil, pave 150-200mm sand cushion for leveling
In case of special foundation, special treatment shall be done to level the subgrade to ensure that the product can be safely transported to the installation site and normal hoisting III: after the products are transported to the construction site, distinguish the water inlet and outlet of the tank body (subject to the direction of inlet and outlet indicated)
Pay attention to safety during hoisting
No one is allowed to stand under the tank body
After the products are hoisted in place, measure the levelness, local commissioning and positioning
Both sides of the tank body shall be backfilled with fine sand immediately, and the position of the tank body shall be fixed to avoid rolling left and right
The steel wire rope can be loosened only after positioning
During backfilling, large hard objects shall not impact the pool body, and it is advisable to tamp it manually in layers, 500 mm for each layer, and local violent impact shall be avoided IV: after the product is positioned, if it is backfilled by machinery, when the arm is low and placed gently, it is forbidden to throw it from high altitude or smash it violently
(special note: fine sand and fine stones must be used for backfilling around the tank body to half or more of the tank body
When backfilling is stopped, mud cannot be used)
Inject clean water immediately
Only when the tank is full of water can it be backfilled completely (if there is groundwater, the tank must be filled with water above the groundwater level before backfilling)
When the water is full, it can be compressed, Anti floating, which is very important in the installation process
Otherwise, if it rains and there is groundwater, the groundwater will cause floating and repeat the construction
nb6h8r5a3  V: after the tank is filled with permanent, the floating soil backfilled at the top of the tank shall not be more than 1
5m high to the road surface
If it exceeds the height, it needs to be strengthened
The treatment scheme: make a reinforced cement panel on the backfilled soil 30-50cm from the top of the tank, and the surrounding of the cement panel shall exceed more than 1m from the surrounding of the tank
The requirements of reinforcement: 12-16, and the spacing of reinforcement shall be 15cm Vi
special attention: when and after the tank is backfilled, it is strictly prohibited to pass the vehicle and stack heavy objects without hardening of the road
During installation, carefully investigate and deal with it flexibly according to the terrain and the actual situation
