Flexible surface layer fabricated soil nail wall structure for foundation pit slope and construction method of flexible surface layer fabricated soil nail wall structure
The invention provides a flexible surface layer fabricated soil nail wall structure for a foundation pit slope and a construction method of the flexible surface layer fabricated soil nail wall structure. Soil nails, flexible surface layers, prefabricated connecting pieces, horizontal beams and inclined beams are included; the flexible surface layers are laid on the side slope; the prefabricated connecting pieces comprise pressing plates and convex blocks; the pressing plates comprise horizontal edges and vertical edges; the convex blocks are arranged at the cross points of the pressing plates,and the vertical sections of the convex blocks are square or rectangular; the prefabricated connecting pieces are arranged in a matrix mode; the convex blocks are vertically pressed on the flexible surface layers; at least one positioning installation hole passage is arranged on the middle part of each prefabricated connecting piece, the horizontal beams are correspondingly arranged between the adjacent prefabricated connecting pieces in the horizontal direction, two ends of the horizontal edges of the pressing plates are pressed on the horizontal beams on both sides; the inclined beams are correspondingly arranged between the adjacent prefabricated connecting pieces in the inclined direction, two ends of the vertical edges of the pressing plates are pressed on the inclined beams on two sides, and the soil nails are correspondingly arranged in the positioning installation hole passages of the prefabricated connecting pieces in a penetrating mode. The technical problems of unclear force mechanism, weak force at joints, waste of building materials, poor environmental protection and low construction efficiency of a traditional soil nail wall structure are solved.
一种基坑边坡的柔性面层装配式土钉墙结构及其施工方法，包括土钉、柔性面层、预制连接件、水平梁和斜梁；柔性面层铺在边坡上；预制连接件包括压板和凸块；压板包括横边和竖边；凸块设在压板十字交点处，凸块的竖向切面呈方形或矩形；预制连接件呈矩阵状布置；凸块垂直压在柔性面层上；预制连接件中部设有至少一个定位安装孔道；水平梁对应设在横向相邻的预制连接件之间；压板的横边两端压在两侧水平梁上；斜梁对应设在斜向相邻的预制连接件之间；压板的竖边两端压在两侧斜梁上；土钉对应穿在预制连接件的定位安装孔道中。本发明解决了传统的土钉墙结构受力机理不清晰、节点处受力薄弱、浪费建筑材料、环保性差和施工效率低的技术问题。
