1, according to the buried sewage treatment equipment installation plan and foundation plan, prepare the foundation to install the size of the floor plan size shall prevail, do a good job of the concrete base plate, the foundation requirements of the average bearing pressure of 5t/m2, the foundation must be horizontal, and should be poured in the concrete foundation maintenance period before installation, such as equipment installed below the floor, the foundation from the floor relative elevation according to the chart dimensions shall prevail, at the same time around the excavation Width, length must be more than 500mm away from the foundation edge line for pipe installation.
2, pipeline installation and connection should be considered in the equipment in place, the equipment must be in place according to the instructions of the equipment weight, with the size of the crane tonnage, the order of installation according to the site against the map in place, the location of the cylinder, the direction can not be put wrong, each other must be correctly spaced.
3, according to the installation plan, connecting pipes, equipment in place after connecting the pipeline with rubber gasket fastened, so that the connection does not leak.
4, buried sewage treatment equipment after the installation of equipment and foundation floor must be connected and fixed, absolutely ensure that the equipment does not make the flow of floating, at the same time must be injected into the equipment in the sewage (no sewage, with other sources of water or tap water instead of), the fullness of the degree of 70% or more must be achieved to prevent the equipment from floating. At the same time, check the pipeline has no leakage. Water test each pipe junction must not leakage, at the same time, the equipment is not subject to ground water rise, and make the equipment misalignment and tilt.
5, equipment installation is completed without error, you can fill in the equipment with soil around the gap in the tamping, and leveling the ground filling of soil should pay attention to:
(1) equipment manhole cover must be about 50mm above the ground;
(2) can not let the soil clogging the manhole cover on the air inlet.
6, the electric control cabinet control line and equipment connected, wiring, pay attention to the underwater aerator and submersible pump motor steering, such as the basement control cabinet should be placed in a ventilated place to keep dry, the general control cabinet can not be placed in the open air. Must prevent sunlight, rain, etc.. In order to avoid control board and terminal leakage, burned control board.
7, buried sewage treatment equipment Note:
(1) equipment must be installed to ensure that the rain does not accumulate water;
(2) equipment outlet pipe must be 0.4m below the relative floor;
(3) equipment shall not be pressed on the top of the heavy objects, there shall not be a large vehicle (refers to the no special design);
(4) The equipment shall not normally be evacuated of internal sewage to prevent groundwater from floating the equipment up.
8, note that the equipment installation diagrams and pipeline connection diagrams according to the standard connection and plane layout, such as user requirements can be arbitrarily arranged, but must be put forward at the time of contracting.
9, connect the fan, pump control lines, and note that the fan, pump steering must be correct.
