Bedding slope reinforcing method and structure
The bedding side slope reinforcing method comprises the steps that S1, multiple rows of miniature prefabricated anti-slide piles are inserted inwards from the slope surface of a bedding side slope, and a space truss pile system is formed; s2, blasting and loosening a soil body in the space truss pile system to form a to-be-grouted cavity wall body with cracks; s3, the cracks in the cavity wall body to be grouted are grouted, so that the pre-embedded retaining wall is formed; and S4, an anchor cable is embedded in the bedding side slope, one end of the anchor cable is fixed to the slope surface, and the other end of the anchor cable is fixed to the side face of the retaining wall. Loosening blasting is carried out in the miniature prefabricated anti-slide piles, original joint cracks are opened, a new crack source is generated, grouting is facilitated, the grouting amount in a space truss pile system is increased, the shear strength is improved, anchor cables are arranged for connection, and the stability of the gradient is further improved.
本发明公开了一种顺层边坡加固方法及加固结构，包括：S1、从顺层边坡的坡面往内插入多排微型预制抗滑桩，形成空间桁架桩体系；S2、对所述空间桁架桩体系内的土体进行爆破松动，形成带有裂隙的待注浆腔墙体；S3、往待注浆腔墙体内的裂隙注浆，以形成预埋式的挡土墙；S4、在顺层边坡内埋设锚索，其中锚索的一端固定于坡面，锚索的另一端固定于挡土墙的侧面。在微型预制抗滑桩内进行松动爆破，使原有的节理裂隙产生张开作用，并产生新的裂源，便于注浆，进而加大空间桁架桩体系内注浆量，提高了抗剪强度，并设置锚索连接，进一步提高了坡度的稳定。
