Leaking stoppage method for foundation pit support structure in open excavation interval of subway station
The invention discloses a leaking stoppage method for a foundation pit support structure in an open excavation interval of a subway station. The leaking stoppage method comprises the following steps that a leaking part of the foundation pit support structure is chiseled into an expanding and repairing hole of which the cross sectional area is gradually reduced from outside to inside; loose concrete, included sand and included mud on the inner wall of the expanding and repairing hole are removed and washed with water; and early-strength cement and water are mixed to form a leaking stoppage material, the leaking stoppage material is kneaded into a material ball to be plugged into the expanding and repairing hole, then the leaking stoppage material is gently smashed and extruded through a stick, and therefore the expanding and repairing hole is plugged. The leaking stoppage method has the advantages of being good in leaking stoppage effect, convenient and fast to construct, wide in application range and the like.
本发明公开了一种地铁站明挖区间基坑围护结构的堵漏方法，包括将基坑围护结构的渗漏部位凿成横截面积由外至内逐渐减小的扩补孔，清除扩补孔内壁上的松散混凝土、夹砂和夹泥，并用水冲洗干净，将早强水泥和水混配形成堵漏材料，将堵漏材料捏成料团塞入扩补孔中，采用棍棒轻砸挤实堵漏材料，将扩补孔封堵的步骤。该堵漏方法具有堵漏效果好、施工方便快捷、适用范围广等优点。
