Intelligent frozen soil nail retaining system
The invention discloses an intelligent frozen soil nail supporting and retaining system, and belongs to the field of slope supporting, the intelligent frozen soil nail supporting and retaining system comprises a frozen soil nail and a supporting and retaining wall, the frozen soil nail is inserted into a soil body drill hole, the frozen soil nail comprises a soil nail rod body with two open ends, and a U-shaped freezing pipe is inserted into the middle position of the soil nail rod body; a U-shaped freezing pipe is arranged at one end of the soil nail rod body, grouting pipes are inserted into the positions, located on the two sides of the U-shaped freezing pipe, in the soil nail rod body, a plurality of grout outlet holes are formed in the outer surface of the other end of the soil nail rod body, the supporting retaining wall covers the side wall of the soil body, and one end of the freezing soil nail extends out of the supporting retaining wall through a hole in the supporting retaining wall. According to the intelligent frozen soil nail supporting and retaining system, the cooling liquid is injected into the soil nails to freeze the soil body, it is guaranteed that the soil nail wall achieves the common soil retaining function, meanwhile, the shear strength of the soil body is instantly improved through freezing when a side slope or a foundation pit deforms greatly under special conditions, then the stability of the side slope or the foundation pit is improved, and the collapse phenomenon of the side slope or the foundation pit is prevented.
本发明公开了一种智能冻结土钉支挡系统，属于边坡支护领域，包括冻结土钉和支护挡墙，所述冻结土钉插入在土体钻孔内，所述冻结土钉包括两端开口设置的土钉杆体，所述土钉杆体的中间位置插入有U型冻结管，且土钉杆体内位于U型冻结管两侧的位置均插入有注浆管，所述土钉杆体的另一端外表面开设有若干个出浆孔，所述支护挡墙覆盖在土体侧壁上，所述冻结土钉的一端通过支护挡墙上的孔洞延伸至支护挡墙的外部。该智能冻结土钉支挡系统，通过在土钉中注入冷却液对土体进行冻结，保证土钉墙在实现普通挡土功能的同时，在特殊情况边坡或基坑发生较大变形时通过冻结瞬时提高土体抗剪强度，继而提高边坡或基坑稳定性，防止其产生坍塌现象。
