Inclined cast-in-situ bored pile construction device
The invention discloses an inclined cast-in-situ bored pile construction device which comprises an outer cylinder, an air bag used for extruding a soil body is arranged on the periphery of the outer cylinder, a fixing ring used for breaking the soil is arranged at the bottom of the outer cylinder, and the bottom of the air bag is connected with the fixing ring. By means of the drilling device, during construction, the outer casing is pre-buried, then drilling operation is conducted, after drilling is finished, the air bag is inflated with air, soil is extruded, compaction is conducted, the soil layer compactness degree is improved, collapse is reduced, and before the casing is taken out, the air is released, and the outer casing can be taken out conveniently.
本发明公开了一种倾斜钻孔灌注桩施工装置，倾斜钻孔灌注桩施工装置包括外筒，外筒外周设有用于挤压土体的气囊，外筒底部设有用于破开土壤固定环，气囊底部与固定环连接。利用本发明的钻孔装置，施工时，预埋外筒然后进行钻孔作业，钻孔结束，向气囊内部充入气体，挤压土体，压实，提升土层紧密程度，减少坍塌，护筒取出前，释放气体，便于外护筒取出。
