电梯井治水堵漏原因及施工方法

1、电梯井渗漏原因
1. Causes of elevator shaft leakage
(1)土建施工时,底板的大量积水没有排干、排净,而直接把混凝土倒入水中,造成底板四周出现很多蜂窝、麻面、孔洞、硫松。
(1) During civil construction, a large amount of ponding on the bottom plate was not drained and drained, but the concrete was directly poured into the water, resulting in many honeycombs, pitted surfaces, holes and sulfur pine around the bottom plate.
2、施工方法:
2. Construction method:
(1)电梯井壁渗漏水原因:因电梯并壁(指正负零水平线以下的井侧壁至底坑四周培面)分作两次水泥砂浆抹面.电梯并侧壁内外均未作防水处理,造成地下水从井例壁外墙进壁内而造成电梯井积水。针对以上渗漏原因,我公司采用 “一堵、二密封、三加强”的施工方法,根*治了电梯井、底板、侧壁的渗漏水。
(1) Cause of water leakage in elevator shaft wall: cement mortar plastering is applied twice for elevator parallel wall (from the shaft side wall below the positive and negative zero horizontal line to the surface around the pit). Waterproof treatment is not applied inside and outside the elevator parallel side wall, resulting in groundwater entering the wall from the outer wall of the shaft wall, resulting in water accumulation in the elevator shaft. In view of the above leakage reasons, our company adopts the construction method of "one plugging, two sealing and three strengthening" to treat the leakage of elevator shaft, bottom plate and side wall.
与底板交接不严实,电梯井底部位置处在正负零水位线下3m,地下水压较大,地下水通过孔洞、麻面、裂缝及疏松处渗漏至底坑,造成电梯井积水。
The connection with the bottom plate is not tight, the bottom of the elevator shaft is 3M below the positive and negative zero water level, the underground water pressure is large, and the underground water leaks to the pit through holes, pits, cracks and loose places, resulting in ponding in the elevator shaft.
(2)电梯并阴角四周严重渗漏原因:因底板先做防水层.再现浇侧壁混凝土墙,这样导致电梯井侧壁混凝土墙跟底板断层.原施工防水层就没有起到应有的防水效果,这样地下水就会不断从断层处渗漏进电梯井内
(2) Causes of serious leakage around the internal corner of the elevator: the waterproof layer is made on the bottom plate first, and the concrete wall of the side wall is poured again, which leads to the fault between the concrete wall of the side wall of the elevator shaft and the bottom plate. The original waterproof layer has not played its due waterproof effect, so the groundwater will continue to leak into the elevator shaft from the fault
