Method for reinforcing foundation pit enclosure
The invention discloses a method for reinforcing foundation pit enclosure. The method is characterized in that a plurality of first multi-curve shaped soil reinforcement blocks are formed by using a first multi-shaft combination drill with three or more shafts to drill downwards to an area below the depth of a foundation pit along the circumferential ground of the foundation pit, so that the enclosure reinforcement is carried out on the edge of the foundation pit, and foundation pit edge reinforcing structures are formed; drill rods of the first multi-shaft combination drill are arranged in anon-linear mode; and parts of construction areas of at least two adjacent drill rods are overlapped. According to the method for reinforcing the foundation pit enclosure, the plurality of multi-curveshaped soil reinforcement blocks are arranged so as to form the foundation pit edge reinforcing structures, the construction overlapping areas in the multi-curve shaped soil reinforcement blocks produced by the multi-shaft combination drill are subjected to breaking construction of at least two drill rods, and after being subjected to multiple breaking construction of the at least two drill rods,soil at the areas is seriously broken, thereby being more com
本发明公开了一种基坑围护强化方法，沿基坑周向的地面向下至基坑深度以下区域通过三轴以上的第一多轴组合钻下钻形成多个第一多曲边形土体加固块对基坑边缘进行围护强化并形成基坑边缘加固结构；所述第一多轴组合钻的钻杆以非直线方式排列，至少有两个相邻的钻杆施工区域部分叠合。本发明提供的基坑围护强化方法为设置多个多曲边形土体加固块形成基坑边缘加固结构，多轴组合钻制成的多曲边形土体加固块中施工叠合的区域经过至少两个钻杆的破碎施工，该区域的土体经过至少两个钻杆的多重破碎施工，土体破碎程度高，与后续固化剂的混合也会更充分，使形成的多曲边形土体加固块具有更好的固化度及更好的止水、挡土、抗弯功能。
