Construction method of foundation pit support structure in existing building in karst area
The invention discloses a construction method of a foundation pit support structure in an existing building in a karst area, and belongs to the technical field of urban underground construction. The construction method of the foundation pit support structure in the existing building in the karst area comprises the steps that S101, the karst area in the building is surveyed; s201, karst pretreatment is conducted, the karst caves are divided into unfilled karst caves, partially filled karst caves and fully filled karst caves according to the size, the filling condition, the burial depth and the stratum condition of the caves according to the exploration result of S101, and filling and grouting are conducted on the ground caves; and S301, filling the hole body, judging the depth of the hole body and the stratum condition according to the survey result of the S101, and performing grouting by drilling and pipe burying. By means of the construction method of the foundation pit support structure in the existing building in the karst area, the disturbance effect on surrounding soil is reduced, deformation of the surrounding earth surface and the building is greatly reduced, the construction efficiency is greatly improved, and the construction cost is reduced.
本发明公开了一种在岩溶区既有建筑内部的基坑围护结构施工方法，属于城市地下施工技术领域。该在岩溶区既有建筑内部的基坑围护结构施工方法包括：S101、对建筑物内岩溶地区进行勘察；S201、岩溶预处理，根据S101的勘察结果将洞体的大小、充填情况、埋深及地层条件将溶洞分为未填充的溶洞、部分填充的溶洞和全填充的溶洞，对地面洞体进行充填注浆；S301、洞体灌填填补，根据S101的勘察结果判断洞体所处的深度、地层条件，并采用钻孔埋管进行注浆。通过使用本在岩溶区既有建筑内部的基坑围护结构施工方法，减少对周围土体的扰动作用，大大减少了周边地表、建筑物的变形，大大增加了施工效率，减轻了施工成本。
