Construction method for urban sewage pump station

Abstract

The invention discloses a construction method for an urban sewage pump. The construction method comprises the following steps of step 1) prefabricating a sewage blocking assembly, wherein the sewage blocking comprises a sewage blocking net, a pair of lifting lugs, a pair of balancing weights and a pair of first lifting mechanisms; step 2) prefabricating a plurality of filter assemblies, wherein each filter assembly comprises a filter screen and second lifting mechanisms; step 3) prefabricating a plurality of submersible sewage assemblies, wherein each submersible sewage assembly comprises a base, a submersible sewage pump, a pair of conveying pipes, a pair of stand columns, a pair of guide blocks and a pair of guide shafts; step 4) erecting a barrier plate in a sewage pool, arranging a plurality of flow guide pipes on the barrier plate in a penetrating manner, erecting a platform template on the downstream side of the barrier plate, and pouring concrete; and step 5) mounting the sewageblocking assembly, the filter assemblies and the submersible sewage assembly in the sewage pool. Sewage pump stations of different scales can be constructed on site according to operation environment, discharge capacity requirement 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...

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
