Deep foundation pit dewatering, purification and recharging all-in-one system and control method

Abstract

The invention relates to a deep foundation pit dewatering, purification and recharging all-in-one system and a control method, and belongs to the technical field of foundation pit engineering. The deep foundation pit dewatering, purification and recharging all-in-one system comprises a plurality of pressure relief wells located in a foundation pit, water pumps located in the pressure relief wells,a plurality of recharging wells located outside the foundation pit, an impounding reservoir, a purification tank and a recharging control system, wherein one end of a water inlet of the impounding reservoir is connected with a multi-way pipe I; a purification filter net is arranged in the purification tank; and the recharging control system comprises a multi-way pipe II and a water valve and a water meter which are arranged on the multi-way pipe II. The deep foundation pit dewatering, purification and recharging all-in-one system can realize all-in-one operation of pressure relief by the pressure relief wells in the foundation pit, initial settlement by the impounding reservoir, effective purification of water by the purification tank and control over water levels in the recharging wellsby the recharging control system, can effectively make use of water resources, and is simple in structure, convenient to operate and low in cost. Meanwhile, the invention further provides a control method of the deep foundation pit dewatering, purification and recharging all-in-one system.

AI Technical Summary

Benefits of technology

This new technology allows for better management of underground resources like foundations or buildings during construction operations while also improving their performance over previous methods. It includes two main steps - firstly it uses an extraction well to extract clean waters before returning them back into the environment after being pumped out again. Secondly, this process helps maintain proper levels within each rechargewell where needed. Additionally, there are systems available on the market that help manage the amount of excess water collected when adding more rainwater without causing damage. Overall, these improvements improve efficiency and effectiveness in managing underground resource usage.

Problems solved by technology

Technological Problem: Deep foundations with multiple relief well arrangements have resulted in increased environmental concerns due to the presence of soil moisture that could affect nearby structures such as buildings or roads during construction operations. To address this issue, various methods for reducing sedimentation within these areas were developed but they may be expensive and require significant space usage. Therefore, it would also benefit by improving upon existing systems without compromising their ability to effectively remove excessive amounts of rainwater.
