Deep foundation pit water-collecting well drainage structure and construction method
The invention relates to the technical field of foundation pit dewatering and drainage, in particular to a deep foundation pit water collecting well drainage structure and a construction method.The drainage structure comprises a deep well, a water collecting pit and a sand-lime-free pipe, the water collecting pit is located at the top of the deep well, and the bottom end of the sand-lime-free pipe extends to the bottom of the deep well; the top end of the sand-lime-free pipe extends into the water collecting pit and protrudes out of the bottom face of the inner wall of the water collecting pit, an outer pipe is fixedly arranged outside the sand-lime-free pipe in a sleeving mode, the outer pipe is located below the water collecting pit and above the half pipe length of the sand-lime-free pipe, and a plurality of settling chambers with the heights sequentially decreased are arranged between the outer pipe and the sand-lime-free pipe. According to the drainage structure, water in the deep well can be drained in time, so that the situation that accumulated water in the deep foundation pit is difficult to infiltrate due to the fact that the deep well is filled is avoided; and the discharged water contains less silt, and the filtering and purifying pressure of a municipal pipe network is reduced, so that the energy consumed in the municipal water supply and drainage process is indirectly reduced, and the purposes of energy conservation and emission reduction are achieved.
本发明涉及基坑降排水技术领域，特别是涉及一种深基坑集水井排水结构及施工方法，其中排水结构包括深井、集水坑和无砂灰管，所述集水坑位于所述深井顶部，所述无砂灰管的底端伸至所述深井底部，顶端伸至所述集水坑内且凸出于所述集水坑的内壁底面，所述无砂灰管外固定地套设有外管，所述外管位于所述集水坑下方、所述无砂灰管一半管长的上方，所述外管与所述无砂灰管之间设有多个高度依次下降的沉淀室。本发明提出的排水结构可以及时排出深井内的水，从而避免深井被灌满而导致的深基坑中积水难以下渗；且排出的水中含泥沙量少，减轻了市政管网的过滤、净化压力，因此间接地降低了市政给排水过程中消耗的能源，达到节能减排目的。
