Sludge cleaning device for foundation pit engineering construction

The invention belongs to the technical field of sludge cleaning, particularly relates to a sludge cleaning device for foundation pit engineering construction, and aims to solve the problem that when an existing sludge cleaning device is used, sludge is usually absorbed through a sludge pump, and the sludge pump is blocked due to the fact that some large objects exist in the sludge. According to the technical scheme, the sludge cleaning device comprises a cleaning box, wherein the top of the cleaning box is fixedly connected with an arc-shaped plate, the inner wall of one side of the cleaning box is slidably connected with a sliding plate, the top of the cleaning box is fixedly connected with an electric telescopic rod, and the telescopic end of the electric telescopic rod penetrates through the cleaning box and is fixedly connected with the top of the sliding plate. The sludge cleaning device is simple in structure and convenient to use; and the sludge can be crushed by crushing wheels under the driving of a
