Treatment method for deep and soft soil foundation of stratum prone to hole collapse
The invention relates to a method for treating a deep soft soil foundation of a hole-easily-collapsed stratum. The method comprises the following steps: drilling a guide hole in a soft soil layer to be treated through a guide hole drill; filling a wall protecting material in the guide hole; the guide hole filled with the wall protection material is subjected to impact reaming by adopting an impact reaming hammer, the wall protection material and a soil body around the guide hole are extruded at the same time, so that the guide hole is provided with an inner-layer stable protection wall and an outer-layer stable protection wall, the outer-layer stable protection wall is the soil body formed through extrusion, and the inner-layer stable protection wall is the wall protection material compacted through extrusion; the replacement holes are filled with reinforcement materials; and tamping the reinforcement material by using a tamping hammer. The method has the advantages that the treatment effect of the soft soil foundation is improved, the problem of easy hole collapse is solved, and implementation of treatment processes such as in-hole dynamic compaction and pre-formed hole deep compaction is facilitated; and the foundation treatment depth is large, the reinforcing effect is good, and the method is suitable for popularization.
本发明涉及一种易塌孔地层深厚软弱土地基处理方法，其在待处理的软弱土地层内通过导孔钻施作导孔；在导孔内填入护壁材料；采用冲扩锤对填入护壁材料的导孔进行冲击扩孔，对护壁材料和导孔周边土体同时进行挤压，从而使导孔具有内、外双层稳固护壁，其中外层稳固护壁为敬扩充挤压形成的土体，内层稳固护壁为经挤压密实的护壁材料；在置换孔内填入增强体材料；采用夯实锤夯击所述增强体材料。本发明的优点是：提高软弱土地基的处理效果，并且解决易塌孔问题，便于孔内强夯、预成孔深层夯实等处理工艺的实施；施工简便且地基处理深度大，加固效果好，适于推广。
