Complex geological karst hole pile foundation construction process
The invention discloses a complex geological karst hole pile foundation construction process. The complex geological karst hole pile foundation construction process comprises the steps that a concrete backfilling karst cave pile foundation construction method or a double-steel-casing all-casing follow-up pile foundation construction method is adopted to perform hole pile foundation construction; when the karst cave where the karst cave pile foundation is located is a small karst cave, hole pile foundation construction is carried out through a concrete backfilling karst cave pile foundation construction method; and when the karst cave where the karst cave pile foundation is located is a large karst cave or a communicating type bead string karst cave group, hole pile foundation construction is carried out through the double-steel-casing all-casing follow-up pile foundation construction method. The conditions of mud loss, wall protection instability and the like of a traditional construction method can be effectively avoided, the construction safety can be effectively guaranteed, the construction period is guaranteed, and meanwhile, the construction cost can be reduced.
本发明公开了复杂地质岩溶孔桩基础施工工艺，采用混凝土回填溶洞桩基施工方法、或者采用双钢护筒全套管跟进桩基础施工方法进行孔桩基础施工；当溶洞桩基所在溶洞为小型溶洞时，采用混凝土回填溶洞桩基施工方法进行孔桩基础施工；当溶洞桩基所在溶洞为大型溶洞、或者连通型珠串溶洞群时，采用双钢护筒全套管跟进桩基础施工方法进行孔桩基础施工。本发明可有效避免传统施工方法出现泥浆流失护壁失稳等状况，可有效保障施工安全，保证施工工期，同时还能降低施工成本。
