Construction disposal method for multi-karst-cave foundation pit in weathered rock stratum area
The invention discloses a multi-karst-cave foundation pit construction disposal method in a weathered rock stratum area, a multi-layer frame structure is arranged in a foundation pit, a middle stand column is arranged in the middle of a frame column, and a pile foundation is arranged below the middle stand column; slope protection piles are arranged on the periphery of the outer side of the frame structure and penetrate through a weathered rock stratum, pile body full-filling karst caves and pile body semi-karst caves are distributed in the middles of the slope protection piles, pile bottom karst caves are distributed at the bottoms of the slope protection piles, foundation pit inner karst caves are distributed in the middle and the bottom of a foundation pit correspondingly, and pile foundation karst caves are distributed at pile foundations. According to the method, three types of karst caves are treated respectively; according to the disposal method, different holes such as drilling holes, grouting holes or feeding holes are respectively disposed; classification is carried out according to the positions of the karst caves, the disposal method is further refined, and disposal is carried out in combination with building characteristics; monitoring and detection in different modes are carried out through different karst cave types, and construction quality and cost control can be guaranteed.
本发明公开了一种风化岩层区内多溶洞基坑施工处置方法，基坑内设置有多层的框架结构，框架柱中部设置有中立柱，中立柱下方设置有桩基，在框架结构外侧四周设置有护坡桩、护坡桩穿过风化岩层且在护坡桩的中部分布有桩身全填充溶洞和桩身半溶洞，在护坡桩底部分布有桩底溶洞，在基坑的中部和底部分别分布有基坑内溶洞坑底溶洞以及在桩基处分布有桩基溶洞；本发明对于三种类型溶洞分别进行处置；且处置方法均通过不同钻孔、注浆或投料等孔洞进行分别处置；通过根据溶洞所在位置进行分类，进一步对处置方法进行细化和结合建筑特点进行处置；通过不同溶洞类型进行不同方式的监测检测，利于保证施工质量和成本控制。
