Prestress assembly type cantilever retaining wall
The invention discloses a prestress assembly type cantilever retaining wall, relates to the field of geotechnical engineering, and solves the problems that an existing assembly retaining wall is poor in structural integrity, and quality defects are prone to occurring at a connecting part. According to the technical scheme, the prestress assembly type cantilever retaining wall comprises two end modules and at least one middle module, wherein the end modules and the middle modules are prefabricated parts of reinforced concrete structures, the middle modules are located between the two end modules and overlapped with the two end modules, the overlapping face is the total cross section of the cantilever retaining wall, each middle module is provided with at least one prestress hole arranged in the direction perpendicular to the overlapping face, prestress anchoring holes are formed in the positions, corresponding to the prestress holes of the middle module, of the end modules, the end modules and the middle modules are connected in series through prestress tendons. and the prestress tendons are fixed in the prestress anchoring holes of the two end modules through anchorage devices. The prestress assembly type cantilever retaining wall is used for slope supporting, and has the characteristics of standardization, modularization, mechanization and convenience in construction.
本发明公开了一种预应力装配式悬臂挡土墙，涉及岩土工程领域，解决现有装配挡土墙结构整体性差，连接部位容易出现质量缺陷的问题。本发明采用的技术方案是：预应力装配式悬臂挡土墙，包括两块端部模块和至少一块中间模块，端部模块和中间模块均为钢筋混凝土结构的预制件，中间模块位于两块端部模块之间并相互叠合，叠合面为悬臂挡土墙的全截面，中间模块设置至少一个沿垂直于叠合面的方向布置的预应力孔，端部模块在与中间模块的预应力孔对应的位置分别设置预应力锚固孔，端部模块和中间模块通过预应力筋串联连接，预应力筋在两块端部模块的预应力锚固孔内通过锚具进行固定。本发明用于边坡支护，具有标准化、模块化、机械化，且便于施工的特点。
