青岛某工程35kV变电站边坡渗漏的治理

Leakage Control of 35kV Slope Substation Project in Qingdao

青岛某工程35 kV变电站场地周边环境及水文地质条件复杂,紧邻海边.施工中支护桩锚杆在钻孔施工穿过旋喷桩止水帷幕后,造成海水不断冲塌上部淤泥层及下部粉砂层,从而导致海水从锚杆部位冲出,发生渗漏现象.施工中有针对性地分别采用背水面注浆法及迎水面补强水泥帷幕桩的施工方法,取得了良好的效果.

The perimeter environment and hydro-geological conditions are complex in a 35 kV substation project,close to the sea,in Qingdao.After the anchorage branched piles bored through the rotating pile waterproof curtain in construction,the sea water crushed the upper silt layer and the lower siltstone layer and caused them to collapse,as a result,the sea water flowed out from the anchor and the leakage occurred.It＇s very effective to use the construction method of the negative side water fill grouting and water attaining surface pile repair.
