Pile-forming construction method for cast-in-situ bored pile in karst area
The invention provides a pile-forming construction method for a cast-in-situ bored pile in a karst area, and is suitable for the field of pile foundation engineering. Comprising the following steps: leveling and positioning a site, burying an outer steel casing, punching to the top of a karst cave, treating the top of the karst cave, lowering an inner steel casing, normally forming a hole to the elevation of a pile bottom and carrying out cast-in-situ bored pile operation. The pile forming construction method for the cast-in-situ bored pile in the karst area is suitable for the field of constructional engineering and has high safety and wide applicability.
本发明提供了一种岩溶区域钻孔灌注桩成桩施工方法，适用于桩基工程领域。包括场地平整与定位、埋设外钢护筒、冲孔至溶洞顶、溶洞顶部处理、下放内钢护筒、正常成孔至桩底标高和进行钻孔灌注桩作业；本发明提供的一种岩溶区域钻孔灌注桩成桩施工方法，适用于建筑工程领域，具有较强的安全性，以及广泛的适用性。
