Problems solved by technology

Since the sewage is directly transported to the sewage treatment plant through the submersible sewage pump, the sewage may block the submersible sewage pump and the conveying pipeline. Currently, the submersible sewage pump for maintenance is pulled to the ground by iron chains, and there is a problem of uneven application of force. The pump is inverted and knocked during the lifting process, causing damage to the structure and further increasing the cost. In the long run, the construction period of the equipment is short, which does not meet the trend and requirements of energy conservation and environmental protection

Abstract

The invention discloses a construction method for an urban sewage pumping station, comprising: step 1) prefabricating a trash block assembly, the trash block assembly including a trash screen, a pair of lifting lugs, a pair of counterweights, and a pair of first lifting mechanisms ; Step 2) prefabricating a plurality of filter assemblies, the filter assembly including a filter screen, a second lifting mechanism; Step 3) prefabricating a plurality of submerged sewage assemblies, the submersible sewage assembly including a base, a submersible sewage pump, a pair of delivery pipes , a pair of columns, a pair of guide blocks, and a pair of guide shafts; step 4) set up a barrier plate in the sewage tank, and a plurality of diversion pipes are pierced on the barrier plate, and a platform formwork is built on the downstream side of the barrier plate, pouring Concrete; Step 5) Install the pollution blocking component, multiple filter components, and the latent pollution component in the sewage pool. The invention can construct sewage pumping stations of different scales on site according to the working environment, discharge volume demand and the like.

Description

technical field [0001] The invention relates to the field of sewage treatment. More specifically, the present invention relates to a construction method of an urban sewage pumping station. Background technique [0002] Municipal sewage treatment usually introduces sewage into the sewage tank through the sewer and then collects it to the submersible sewage pump, lifts it through the submersible sewage pump and transports it to the sewage treatment plant through the ground drainage pipeline for treatment. Since the sewage is directly transported to the sewage treatment plant through the submersible sewage pump, the sewage may block the submersible sewage pump and the conveying pipeline. Currently, the submersible sewage pump for maintenance is pulled to the ground by iron chains, and there is a problem of uneven application of force. The pump is inverted and knocked during the lifting process, causing damage to the structure and further increasing the cost. In the long run, t...
