Assembly cantilever type concrete retaining wall
The invention relates to an assembled cantilever type concrete retaining wall which comprises a retaining wall bottom plate and a plurality of prefabricated wall plates sequentially arranged in the left-right direction, and a plurality of bottom plate positioning inserting grooves sequentially arranged in the left-right direction are formed in the upper end of the retaining wall bottom plate. The bottom of each prefabricated wallboard is provided with at least two wallboard vertical positioning protrusions which are inserted into the corresponding bottom plate positioning inserting grooves in a positioning mode, vertical prestressed tendons are vertically arranged in the prefabricated wallboards and the retaining wall bottom plate, the front sides of the prefabricated wallboards are soil retaining sides, and diagonal braces are arranged between the front sides of the prefabricated wallboards and the upper end of the retaining wall bottom plate. Wallboard shear-resistant structures which are positioned and matched in a concave-convex mode in the front-back direction are arranged between the adjacent prefabricated wallboards, and transverse prestressed tendons with the length extending in the left-right direction are arranged between the two adjacent prefabricated wallboards. The concrete retaining wall solves the technical problems that the connecting force between prefabricated wall plates of an existing concrete retaining wall is not strong, and the horizontal load resistance is poor.
本发明涉及一种装配悬臂式混凝土挡土墙，包括挡土墙底板和多个沿左右方向顺序布置的预制墙板，挡土墙底板上端设置有多个沿左右方向顺序布置的底板定位插槽，各预制墙板底部设置有至少两个分别与对应底板定位插槽定位插装的墙板竖向定位凸起，预制墙板和挡土墙底板内设置有竖向设置的竖向预应力筋，预制墙板的前侧为挡土侧，预制墙板的前侧和挡土墙底板上端之间设置有斜拉筋，相邻的预制墙板之间设置有沿前后方向凹凸定位配合的墙板抗剪结构，相邻两个预制墙板之间设置有长度沿左右方向延伸的横向预应力筋。本发明解决了现有混凝土挡土墙的预制墙板间连接力不强而水平抗荷载能力差的技术问题。
