Problems solved by technology

[0003] Conventional dewatering well closure adopts the scheme of buried pump. The water pump is buried in the dewatering well, and then backfilled with gravel to ensure that there are no cavities at the bottom of the foundation. Due to the quality of the filter material and improper handling during backfilling, it is easy to cause damage to the submersible pump or drainage pipes. 1. The water pump cable is damaged. If the water pump or drain pipe is damaged when backfilling the filter material, improper handling will cause the groundwater level to rise, affect the construction progress, and bring greater economic losses to the construction. Therefore, how to avoid doing so when backfilling the filter material in the well? It is very important to protect the submersible pump and avoid affecting the normal operation of the precipitation system due to the backfill of the filter material

Abstract

The invention discloses a submersible pump protection device used during drain well sealing. The submersible pump protection device comprises a pump body protection device, wherein a cable protectioncover is arranged at the top of the pump body protection device to protect a cable, and a water pump bottom limiting device is fixedly arranged at the inner bottom of the pump body protection device to limit a submersible pump; and the pump body protection device comprises a pump body protection cover, wherein the pump body protection cover is provided with an inner cavity, the submersible pump isarranged in the inner cavity of the pump body protection cover, a reserved hole is formed in the top of the pump body protection cover, the cable protection cover is fixedly arranged at the reservedhole, and the bottom of the pump body protection cover is blocked.

Description

technical field [0001] The disclosure belongs to the technical field of engineering construction equipment, and in particular relates to a protection device for a submersible pump used to dry wells and seal wells. Background technique [0002] With the acceleration of urbanization, the exploration, development and utilization of urban underground space has become an important measure to make full use of land resources and ensure the sustainable development of cities. However, the development and utilization of urban underground space in water-rich areas often requires precipitation to successfully complete the entire construction. Before the excavation of the deep foundation pit, dewatering work is required. However, after the excavation of the foundation pit is completed, it is more important to deal with the drainage well inside the foundation pit. [0003] Conventional dewatering well closure adopts the scheme of buried pump. The water pump is buried in the dewatering wel...
