The entire process of lifting and backfilling of sewage lifting integrated pump station
In the case of carrying out specific engineering construction in the sewage lifting integrated pumping station, relevant safety technical disclosure work must be done well before installation. The drainage equipment in the construction area of all sewage treatment plants should be constructed according to the specific situation of each sewage prefabricated pumping station, taking into account the geological and geomorphological standards, as well as the size of the discharge volume, and then carrying out the overall planning and layout of the engineering construction. In addition, in the specific construction of the engineering, the engineering construction system software consistent with the drainage equipment outside the plant should be considered. Before installing the equipment in the sewage prefabricated pumping station, it is necessary to scientifically study the relevant mechanical equipment installation drawings and clarify the construction technology selected for electrical equipment, In addition, it is necessary to establish a detailed construction quality inspection procedure throughout the entire process of engineering construction.
1、 Integrated sewage lifting pump station lifting
Lift the pump station from the horizontal position to the vertical position using an elevator lasso. In this work, the lifting hooks on the casing are not allowed to be used.
When lifting prefabricated pump stations vertically, the lifting hook support should be symmetrical. It is advisable to use hoisting ropes or ropes to maintain the pump station and pump cover to prevent them from being pinched.
Before installation, use a brush to clean the surface of the concrete base plate to ensure that there is no soil or dirt between the installation surface and the pump installation flange
When lifting the pump station, the inlet and outlet trade directions of the pump station should be consistent with the inlet and outlet directions.
The pumping station should be installed vertically and fixed with anchor bolts.
2、 Backfilling and compaction of pump pits in integrated sewage pumping stations
The backfilling of the pump pit should be carried out after the accurate installation of the pump station cylinder.
The raw materials for backfill soil should be river pebbles, stone sand, gravel soil, and sand. The particle size should not exceed 13-25mm.
The backfill soil should be backfilled layer by layer, and the height to width ratio of each layer should not exceed thirty centimeters. The compactness of the backfill should comply with the design scheme and the requirements of 6.3 in the "Code for Acceptance of Construction Quality of Building Foundation Engineering" GB50202.
The backfill at the inlet and outlet of pit 4 should be compacted. When backfilling the soil layer to a distance of 30 centimeters from the pump head to the top of the wall, it is prohibited to use machinery and equipment such as compactors.
The quality engineering acceptance of backfill soil should comply with the requirements of the "Code for Acceptance of Construction Quality of Building Foundation Engineering" GB50202 and the "Standard for Quality Inspection and Evaluation of Building Engineering" GB50300.
