Method for closing dewatering well in foundation pit
The invention discloses a method for closing a dewatering well in a foundation pit, and belongs to the technical field of waterproof construction of constructional engineering. The construction method comprises the following specific construction steps: firstly, processing and manufacturing the steel sleeve (2); the steel sleeve (2) is connected to the precipitation well wall (1) in a sleeving mode, and cushion layer concrete (3) is poured; impervious self-compacting concrete (4) is filled between the steel sleeve (2) and the precipitation well wall (1); a waterproof and waterproof protective layer (5) is constructed on the outer side of the steel sleeve; raft reinforced concrete (6) is constructed, and a water stop steel plate (12) is arranged at the 2/3 height of the raft; and the self-compacting raft reinforced concrete (8) is constructed by closing the steel sleeve flange cover (7). The method has the advantages that the steel sleeve is easy and convenient to manufacture and easy to block and construct, the dewatering well in the foundation pit is well sealed, a basement is prevented from upwelling and permeating into a room in the later period, the later leakage risk is greatly reduced, and the maintenance cost is reduced.
一种封闭基坑内降水井的方法，属于建筑工程的防水施工技术领域。具体施工步骤如下：先加工制作钢套管(2)；将钢套管(2)套接在降水井壁(1)上，浇筑垫层混凝土(3)；钢套管(2)与降水井壁(1)之间采用抗渗型自密实混凝土(4)灌满；钢套管外侧施工防水及防水保护层(5)；施工筏板钢筋混凝土(6)，在筏板2/3高度处设止水钢板(12)；封闭钢套管法兰盖(7)施工自密实筏板钢筋混凝土(8)。优点在于，钢套管制作简便，易于封堵施工，对基坑内降水井封闭性好，防止后期地下室上涌渗入室内，极大的降低后期渗漏风险，减少维修成本。
