The application discloses a kind of for urban river channel silt reduction construction method, adopt rubber dam and store pit combination, store pit reduces water flow velocity, changes vertical distribution of silt, and makes silt particles concentrate downward, rubber dam adopts arch design, while weakening the impact of water flow on rubber dam, the silt in the silt source of upstream river channel is intercepted, so that it is accumulated to selected section convenient for mechanical dredging;Then, using the way of mechanical dredging, the sludge accumulated is removed for treatment after processing.The application has the advantages of simple and fast design, and the designer only needs to record the data such as river width, normal water level height, water flow velocity and model scale test, so as to carry out the design calculation of actual engineering.The method improves the dredging efficiency, reduces the silt accumulation of urban internal river channel, reduces the traffic pressure of urban internal river channel, and saves manpower and material resources.

This application relates to a sponge city infiltration and drainage system, including a first drainage unit, drainage wells, a water storage tank, and a second drainage unit. The first drainage unit includes a permeable pavement and multiple infiltration pipes. Along a first direction, the multiple infiltration pipes are located at the lower part of the permeable pavement, and the first direction is the direction of gravity. The drainage wells are connected to the permeable pavement through the infiltration pipes. There are multiple drainage wells, which are connected to each other through a main drainage pipe. A convection mechanism is installed in the drainage well, which is configured to convect at least a portion of the rainwater entering the drainage well to reduce sediment deposition in the drainage well. The water storage tank is connected to the drainage wells through a connecting pipe. The second drainage unit includes a drainage channel and a sand discharge port. The drainage channel has an inlet end and an outlet end. The inlet end is located on the road surface, and the outlet end is connected to at least a portion of the drainage wells. The sand discharge port is located on the path between the inlet end and the outlet end, and is configured to filter sediment from the water entering from the inlet end.

The utility model discloses a building engineering drainage device relates to building engineering technical field, including the vehicle body, the surface of vehicle body is provided with pumping mechanism, the surface of vehicle body is provided with filter mechanism. The utility model discloses through setting up the battery for sewage pump and drainage pump power supply in the inside of vehicle body, setting the fixing base on the surface of vehicle body, make to the sewage pump is fixed, prevent the sewage pump activity when vehicle body removes, through placing sewage pump in the frame, the frame all around with bottom end all is provided with the screen, is used for the filtration of big granular solid, will the clamping block aim at the slurry pump, promotes sewage pump to displace downward, make the clamping block along slurry pump into annular groove, frame can be fixed at this time rotates, and the model of sewage pump is 65WQ30 40 7.5, can cope with silt sewage, and the water level is still can drain when lower end pumping makes, adapts the waterlogging environment of site, has improved the adaptability of device.
