[0002] Rail transit civil construction is a kind of building construction, and the foundation pit excavated in the process of rail transit civil construction often enters recharge water to affect the progress of construction. Since the foundation pit is dewatered, the groundwater level around the foundation pit inevitably decreases, thereby causing the original buildings and underground structures around the foundation pit to be damaged to different degrees due to uneven settlement. In order to reduce the above influences or damages, recharge measures should be taken between the foundation pit and the buildings to be protected. According to the stratum characteristics of the foundation pit, the recharge measures use a recharge well outside the pit. Water in the foundation pit is pumped into the recharge well by a water pump to perform recharge operation. In recharge operation, the existing recharge water treatment device usually uses a filtration treatment method to filter and intercept solid impurities to avoid a large amount of solid impurities from entering the recharge well to cause blockage.
