Efficient foundation pit dewatering structure
The invention relates to an efficient foundation pit dewatering structure. The efficient foundation pit dewatering structure comprises a water filtering pipe pre-buried around a foundation pit, wherein an annular main pipe is arranged at the top end of the foundation pit, a bent connecting pipe is arranged between the water filtering pipe and the main pipe, one end of the bent connecting pipe communicates with the top end of the water filtering pipe, the other end of the bent connecting pipe communicates with the main pipe, a water pumping device is connected to the main pipe, first drainage wells are dug around the foundation pit, second drainage wells are dug on the sides, close to the foundation pit, of the first drainage wells, communicating pipes are arranged between the first drainage wells and the second drainage wells; one end of each communicating pipe communicates with the bottom of the corresponding first drainage well, and the other end of each communicating pipe communicates with the bottom of the corresponding second drainage well; gates are inserted in the middles of the communicating pipes; steel ropes are connected to the gates, and the other ends of the steel ropes are fixedly connected to the ground; and floating plates are arranged in the first drainage wells, and ejector rods used for jacking the steel ropes are connected to the floating plates. The efficient foundation pit dewatering structure has the effects that the water level descending difference around the foundation pit is reduced, and buildings around the foundation pit are uniformly settled.
本申请涉及一种高效的基坑降水结构，其包括预埋在基坑四周的滤水管，基坑顶端的设置有环形的总管，滤水管与总管之间设置有弯联管，弯联管一端与滤水管的顶端连通，弯联管的另一端与总管连通，总管上连接有抽水装置，基坑的四周均挖设有第一排水井，第一排水井靠近基坑的一侧挖设有第二排水井，第一排水井与第二排水井之间设置有连通管，连通管的一端与第一排水井的底部连通，连通管的另一端与第二排水井的底部连通，连通管的中部插设有闸门，闸门上连接有钢绳，钢绳的另一端固定连接在地面上；第一排水井内设置有浮板，浮板上连接有用于将钢绳顶起的顶杆。本申请具有缩小基坑周围的水位下降差，使得基坑周围的建筑物均匀沉降的效果。
