Method for constructing pile foundation in karst cave stratum
The invention relates to the technical field of building construction, in particular to a method for constructing a pile foundation in a karst cave stratum. The method for constructing the pile foundation in the karst cave stratum comprises the following steps that step 1, geographic exploration is carried out on a construction section, wherein the geographic exploration comprises karst cave sizemeasuring, karst cave diameter measuring and karst cave depth measuring, and the location and distribution of a karst cave group are determined; step 2, grouping is carried out according to the vertical distribution and the horizontal distribution of the karst cave group; and step 3, independent operation units are divided according to the grouping of the karst cave group in the step 2, and unified drilling and unified backfilling operation are carried out on the grouped operation units of the unified karst cave group. The pile foundation construction can be carried out in the karst cave section.
本发明涉及建筑施工技术领域，特别为一种溶洞地层桩基施工方法。本发明包括如下步骤：步骤一：对施工段进行地理勘查，所述地理勘测包括测量溶洞大小、溶洞直径、溶洞深度，并确定溶洞群的位置及分布情况；步骤二：根据溶洞群竖向分布和横向分布情况进行分组；步骤三：根据步骤二的溶洞群分组情况划分独立作业单元，对统一溶洞群分组的作业单元进行统一钻孔及统一回填操作。本发明能够在溶洞地段进行桩基施工。
