Steel casing supporting method construction orifice support for special karst pile foundation
The invention provides an orifice support for special karst pile foundation steel casing supporting method construction, and relates to the technical field of karst pile foundation steel casing supporting frames. The orifice support comprises a foundation, a pile foundation hole is formed in the middle of the foundation, a preliminary welding pile casing and a welded pile casing are arranged in the pile foundation hole, a pile casing to be welded is arranged at the upper end of the preliminary welding pile casing, and first steel plates are arranged at the front end and the rear end of the middle of the upper surface of the foundation correspondingly; second steel plates are arranged on the two sides of the middle of the upper surface of the foundation, and first long I-shaped steel is arranged at the end, close to the center of the pile foundation opening, of the upper surface of each first steel plate. According to the steel casing supporting method construction orifice support for the special karst pile foundation, construction is carried out by using the orifice support on site in a welding and fixing mode, field leveling construction is avoided while one truck crane platform is saved, the construction cost is reduced, and meanwhile the karst pile foundation construction safety is improved.
本发明提供一种用于特殊岩溶桩基钢护筒支护法施工孔口支架，涉及岩溶桩基钢护筒支护架技术领域。该孔口支架，包括地基，所述地基的中部开设有桩基开孔，所述桩基开孔的内部分别设置有初步焊接护筒和焊接完成护筒，所述初步焊接护筒的上端设置有待焊接护筒，所述地基上表面中部的前端和后端均设置有第一钢板，所述地基上表面中部的两侧均设置有第二钢板，所述第一钢板上表面靠近桩基开孔中心处的一端均设置有第一长工字钢。本发明提供一种用于特殊岩溶桩基钢护筒支护法施工孔口支架，通过现场使用孔口支架加上焊接固定方式进行施工，节省了1台汽车吊台班的同时避免场平施工，降低施工成本同时增加岩溶桩基施工安全性。
