The glass reinforced septic tank is made of high strength acid and alkaline resistant materials such as glass fiber and organic resin. It is mainly used as a kind of equipment for wastewater purificat

The hoisting method of the GRP septic tank is based on the principle of safe and convenient operation. According to the actual situation of the construction site, the hoisting method of combining machinery and manpower can be adopted. Let's understand the precautions for the installation of the GRP septic tank as follows:

1. Before hoisting, the foundation pit shall be dug well, and the foundation pit shall be provided with cushion and leveled to avoid the instability of the glass reinforced septic tank;

2. When hoisting the glass reinforced septic tank, it shall be tied with non-metallic rope, and it shall not be hoisted,

3. Pay attention to the inlet and outlet direction of the septic tank when hoisting. The end indicated by the arrow is the outlet direction,

4. In the process of hoisting, the glass reinforced septic tank shall be balanced into the pit and shall not collide with the pit wall or pit bottom to ensure that the tank wall does not collapse.

5. The elevation of the glass reinforced septic tank shall meet the engineering design requirements, be far away from the water source and the wall, and shall be constructed according to the drawings.

6. After hoisting in place, measure the levelness, locally adjust the cushion to make it horizontal, and then backfill the sand to compact the sand to the road surface.

7. After the septic tank is installed, it will be connected to the new sewage system. The diameter of the inlet pipe and outlet pipe of 40 cubic meter septic tank is 150-200mm, which can be directly built into the shaft wall. The joint between the outer wall of the pipe and the shaft wall shall be filled with 1:2 or 1:3 cement mortar.

After the installation of the GRP septic tank in place meets the requirements, the tank must be filled with water above the groundwater level to make it stable before backfilling. Before covering the soil, the closed water test must be carried out in accordance with the code for construction and acceptance of water supply and drainage pipeline engineering, and the soil can only be covered after passing the inspection.
