Foundation pit dewatering supporting device and construction method
The invention relates to a foundation pit dewatering supporting device and a construction method, and relates to the field of foundation pit dewatering technologies. The device comprises a dewatering well, a filter pipe, a water conveying pipe, water pumping equipment, a cleaning cylinder and a supporting cylinder, a plurality of filtering holes are formed in the outer circumferential wall of the filtering pipe, the top end of the filtering pipe communicates with a water conveying pipe, and the water conveying pipe extends out of the dewatering well and is connected with water pumping equipment; the dewatering well is filled with a first coarse sand layer and a clay layer; the cleaning cylinder is connected above the filter pipe through a telescopic rod piece, the inner diameter of the cleaning cylinder is the same as the outer diameter of the filter pipe, and a pull rod is arranged on the cleaning cylinder; the cleaning cylinder is sleeved with the supporting cylinder, the top end of the supporting cylinder is provided with a pull sleeve penetrating out of the dewatering well and fixed to the dewatering well, the pull sleeve is communicated with the interior of the supporting cylinder, and the pull rod penetrates out of the pull sleeve. By means of the first coarse sand layer, the second coarse sand layer, the net bag and the filter pipe, multi-layer filtration of seepage water is achieved, the content of silt in pumped water is reduced, and the protection effect on the water pumping equipment is achieved.
本申请涉及一种基坑降水支护装置及施工方法，涉及基坑降水技术的领域。其包括降水井、滤管、输水管、抽水设备、清理筒和支撑筒；滤管位于降水井内，滤管外圆周壁开设有若干滤孔，滤管顶端与输水管连通，输水管伸出降水井外并与抽水设备连接；降水井内填充有第一粗砂层和黏土层；清理筒通过伸缩杆件连接在滤管上方，清理筒内径与滤管外径相同，且清理筒上设有拉杆；支撑筒套设在清理筒外侧，支撑筒顶端设有穿出降水井外并与降水井相固定的拉套，拉套与支撑筒内部连通，拉杆从拉套内穿出。本申请通过第一粗砂层、第二粗砂层、网兜和滤管实现了对渗水的多层过滤，减小了抽水中泥沙的含量，起到对抽水设备的保护作用。
