某公寓楼为地上10层、地下1层的高层建筑。由于地质勘探工作的疏漏,基础开挖时基坑多处出水;设备间与地下室连接,设备间基坑低于整个基础底部约2 m,其边坡水头多、出水量较大且喷射高20~30mm,带一定压力。基坑开挖后,100 mm垫层无法施工,卷材防水层更无从完成。开凿降水井及从基坑外围降水的条件都不具备。这种情况下,先后用SBS卷材、钢板网抹灰、钢板封堵等多种办法封堵,均毫无效果。各种办法失败的情况下,以“片石疏水法”治理,收到了意料之外的好效果。基 An apartment building on the ground 10 floors, 1 basement high-rise buildings. Due to the omission of geological exploration work, the foundation pit has many outlets during the foundation excavation; the equipment rooms are connected with the basement, the foundation pit of the equipment is lower than about 2 m at the bottom of the whole foundation, and the water head of the slope is large, the water discharge is large and the injection height is 20 ~ 30mm, with a certain pressure. Excavation of the foundation pit, 100 mm cushion can not be constructed, the membrane waterproof layer even more impossible to complete. Excavation of wells and precipitation from the outer periphery of the pit conditions are not available. In this case, SBS membrane, steel mesh plastering, steel sealing and other methods have been blocked, all with no effect. In the case of failure of all kinds of methods, the “stone slaty hydrophobic law” governance, has received unexpected good results. base
