In order to ensure the construction quality and improve the construction safety, it is necessary to drain the water in the foundation pit in time.

[0003] At present, during the emergency rescue of pumping water in deep foundation pits, a nylon rope is mostly used to tie the water pump and manually pull it down into the foundation pit. At the same time, since the water belt is placed on the retaining wall of the foundation pit, and the water pump sinks in the water by its own weight, at the contact part between the water belt and the retaining wall of the foundation pit during the pumping process, the water belt will be bent, resulting in a reduction in water flow, a decrease in pumping efficiency, a large self-weight generated by the rising initial water column in the deep foundation pit during pumping, a large tensile force on the water outlet end of the water belt, and it is very difficult to fix the water belt.

[0004] Therefore, we propose a support and fixing device for flood drainage and emergency rescue in deep foundation pits to solve the above problems. Content of the Utility Model
