Complex geological pile foundation combined hole-forming construction method
The invention relates to a complex geological pile foundation combined hole forming construction method, which adopts a hanging type operation platform steel casing deformation treatment technology, a plurality of profile steel supports are arranged at different heights in a deformed steel casing at intervals, and a hanging type operation platform is arranged for treating a steel casing deformation accident in a pile foundation construction process in a complex environment. The profile steel support can be repeatedly used, so that the construction efficiency and economical efficiency of accident treatment are improved; a salvage technology for coping with drill falling in a down-the-hole hammer hole is provided, a drill bit salvage device is designed, the success probability of drill bit capturing is improved, and a water passing hole and a water draining opening are formed in the salvage device and used for reducing water buoyancy of the whole device; the lowering position of the wireless high-definition camera can be adjusted according to the diameter of the cast-in-place pile and the position of the detection hole, and high-definition camera shooting of the pile foundation concrete pouring quality is achieved.
本发明涉及一种复杂地质桩基组合成孔施工方法，采用了吊挂式操作平台钢护筒变形处治技术，在变形钢护筒内不同高度处间隔设置多个型钢支撑，并设置吊挂式操作平台，用于复杂环境下桩基施工过程中钢护筒变形事故的处理，型钢支撑可重复使用，提高了事故处理的施工效率和经济性；提出了一种应对潜孔锤孔内掉钻的打捞技术，设计了钻头打捞装置，提高了钻头捕获的成功几率，打捞装置上设置过水孔及疏水口，用于减少整个装置的水浮力；可以根据灌注桩的直径和探测孔的位置调整无线高清摄像头的下放位置，实现了桩基混凝土灌注质量的高清摄像。
