Karst cave foundation pit supporting construction method
The invention relates to the field of building construction, and discloses a karst cave foundation pit supporting construction method. The karst cave foundation pit supporting construction method comprises the steps that (a) modeling through BIM and design drawing, (b) excavation of foundation pits, (c) staking out in survey, (d) embedding of a pile casing, (e) preparation of wall protection mud,(f) installation and positioning of a drilling rig, (g) drilling, (h) hole cleaning, (i) construction of a steel reinforcement cage production platform, (j) steel reinforcement cage production, (k) steel reinforcement cage lifting and (l) pouring are carried out, specifically, a geological survey report is used, the deformation of soil bodies under different working conditions is analyzed througha BIM three-dimensional solid model; a supporting pouring pile determines the communication condition of a karst cave in the form of a jump, rocks and the soil bodies in the foundation pits are takenand stirred for karst cave filling, and safety and efficiency are achieved; large karst caves are wrapped by closing nets welded to a steel reinforcement cage to reduce concrete filling and effectively reduce costs; and a mud separator is used for cleaning particles in the mud, and recycling and environment protection are achieved.
本发明涉及建筑施工领域，公开一种溶洞基坑支护施工方法，包括步骤（a）BIM建模设计图纸→（b）基坑开挖→（c）测量放样→（d）埋设护筒→（e）制备护壁泥浆→（f）钻机安装定位→（g）钻孔→（h）清孔→（i）搭建钢筋笼制作平台→（j）钢筋笼制作→（k）钢筋笼吊装→（l）灌注；利用地质勘察报告，通过BIM三维实体模型，分析不同工况下土体的变形；支护灌注桩以跳打形式判定溶洞连通状况，取用基坑内的岩石和土体搅拌进行溶洞填充，安全高效；大溶洞通过钢筋笼上焊接收口网包裹，减少混凝土填充，有效降低成本；采用泥浆分离器清理泥浆中颗粒，回收循环利用，绿色环保。
