Soil nailing wall construction method for pre-reinforcing side slope rock-soil body
The invention discloses a soil nailing wall construction method for a pre-reinforced side slope rock-soil body in the technical field of side slope reinforcement. The soil nailing wall construction method comprises the steps that S1, the pre-reinforced side slope rock-soil body is trimmed; s2, the slope gradient and the punching position are determined; s3, an excavator excavates a rock-soil body layer by layer along the slope surface of the side slope by adopting an S-shaped operation route, and a drilling machine synchronously works in a staggered mode to install soil nails; s4, according to the positions of the soil nail holes, third threaded holes are drilled in the corresponding positions of the prefabricated slabs in sequence, and the prefabricated slabs are spliced layer by layer; s5, fastening and connecting the reinforcing steel bars and the prefabricated slabs through the connecting pieces; and S6, coping construction is conducted. According to the scheme, an S-shaped operation route layered excavation and staggered synchronous anchoring construction method is adopted, the rock-soil body of the current layer is punched and reinforced before the next layer is excavated, the risk that the rock-soil body collapses due to external factors in the construction process is reduced, an excavator and a drilling machine can alternately rest, long-time construction of construction equipment is avoided, and the construction efficiency is improved. Safety risks caused by mutual influence during synchronous operation of the excavator and the drilling machine are reduced, and meanwhile construction efficiency is improved.
本发明公开了边坡加固技术领域的一种预加固边坡岩土体的土钉墙施工方法，包括：S1、修整预加固边坡岩土体；S2、确定放坡坡度和打孔位置；S3、挖机沿边坡坡面采用S型作业路线逐层开挖岩土体，钻孔机错位同步作业安装土钉；S4、根据土钉孔位置，依次在预制板对应位置钻第三螺纹孔，将预制板按层拼接；S5、连接件紧固连接钢筋与预制板；S6、压顶施工。本方案采用S型作业路线分层开挖，错位同步锚固的施工方法，在下一层开挖前对当前层的岩土体进行打孔加固，降低了施工过程中外界因素导致岩土体坍塌的风险，且挖机和钻孔机能够交替休息，避免施工设备长时间施工，降低了挖机和钻孔机同步作业时相互影响产生的安全风险，同时提高了施工效率。
