Installation of Henan Kaifeng Integrated Prefabricated Pump Station
Specific installation process of integrated sewage lift pump station
For the installation of the integrated sewage lift pump station, the structure of the site is very important. For this reason, the site must be inspected before installation to formulate the excavation plan, and the foundation pit must be closely watched during excavation.
No water is allowed. If there is, proper precipitation measures must be taken. Proper foundation pit maintenance shall be adopted to avoid collapse of pump pit.
The bottom of the pit shall be excavated and leveled. If necessary, a layer of stone free pebble shall be paved and compacted with a compactor to a degree of 90% of compaction test results. After the excavation of the pump pit is completed, the installation of the pump station can only be carried out after confirming that the site conditions such as the inlet and outlet pipe connecting pipes and cables of the pump station are available.
In order to consider the stability of the slope, possible drainage methods, etc., should be suitable for the current soil environment. A small sump can be built at the edge of the pit bottom to drain water at any time to ensure that there is no ponding on the pit bottom plane.
Excavation must be carried out according to the design drawings: construction setting out shall be carried out according to the plane position, elevation and geometric dimensions designed in the drawings. Extend the foundation pit control pile outside the foundation pit It shall be fixed at 2m. The foundation pit excavation shall maintain good drainage. A collecting well shall be set outside the foundation pit to facilitate the drainage of the base.
Excavate to the medium sand layer with excavator, remove the upper filling, and then backfill to the base elevation with coarse sand After the foundation pit is excavated, the bearing capacity of the foundation base shall be checked. If the bearing capacity fails to meet the requirements, it shall be handled according to the instructions of the supervising engineer.
To ensure the normal operation of the integrated sewage lift pump station, the bottom foundation must be laid, the bottom must be paved, sand filled and compacted.
Ensure that there is no dirt or other sundries between the mounting surface and the pump mounting flange. Lift the pump body with a lifting hook and place it in the middle of the anchor screw ring on the cement base plate.
During operation, do not touch the pump body with the foundation screw, because the foundation screw is easy to damage the pump body surface. Pay attention to confirm the correctness of the inlet and outlet directions of the tank, and pay attention to the need to fall in the center of the concrete foundation to ensure that the pressure on the compacted layer is uniform. Check whether the pump station is vertical.
What is the advantage of sewage lift pump station?
The integrated sewage pump station is applicable to places that cannot rely on the gravity effect to discharge sewage by themselves. It collects waste water below the water level of the waterway through the sewage tank, as well as waste water discharged far away from the municipal sewage pipe network and sanitary equipment, and transmits the sewage to the sewage pipe network with the help of the sewage pump.
1. Short construction period: within two weeks, you can complete the procedures including excavation, backfilling, compaction, connection, leakage inspection, control system equipment, test run, final commissioning and everything.
2. Strong anti leakage function: the barrel is surrounded by the computer control shaft, with high integration of one-time molding, and anti leakage and crack.
3. Integrated planning: integrated planning shall be carried out for the components in the water of the pump station and the overall destructive ventilation system.
4. Analysis: Hydrodynamic planning is selected to actively clean to prevent blocking.
5. Strength analysis and inspection: each product shall be analyzed and inspected before delivery to ensure the reliability of the product.
6. Intelligent control system: there is no need for special personnel to be on duty, GPRS long-distance system, knowing the operation of the pump station at any time and anywhere. The equipment is also relatively simple, and its corrosion resistance is also very strong. It can effectively improve the service life during use, basically without daily protection, and its failure rate is very low.
