Ultrahigh counterfort retaining wall composite structure
The invention relates to the technical field of supporting structures, in particular to an ultrahigh buttress type retaining wall composite structure and a construction method thereof.The ultrahigh buttress type retaining wall composite structure comprises cast-in-place piles pre-buried underground, a buttress type retaining wall is installed at the top of a bearing platform, a plurality of horizontal hidden supports are poured on one side face of the bearing platform side by side, and the horizontal hidden supports are located on the front side face of the buttress type retaining wall; the pile foundation of the cast-in-place pile is arranged at the position corresponding to the counterfort type retaining wall, so that loads can be better transmitted to the pile foundation, and the foundation of the cast-in-place pile can be effectively prevented from being damaged due to the fact that the pile foundation of the cast-in-place pile is arranged at the position corresponding to the counterfort type retaining wall. The pile foundation bearing platform is used for solving the anti-overturning stability problem, the bearing platform is directly used as a bottom plate of the counterfort type retaining wall, a retaining wall bottom plate is not additionally arranged, the problem that the retaining wall bottom plate and the bearing platform are connected through steel bars and are not stable is solved, the structure is more reliable, horizontal loads are counteracted through the hidden supporting beams, and the anti-sliding stability of the structure is guaranteed; and the safety reserve of the structure is increased.
本发明涉及支护结构技术领域，具体为一种超高扶壁式挡墙组合结构及其施工方法，包括预埋在地下的灌注桩，承台顶部安装有扶壁式挡墙，承台一侧面并排浇注有若干个水平暗撑，水平暗撑位于扶壁式挡墙的前侧面，扶壁式挡墙的墙后地面回填有粘土填料，粘土填料内沿扶壁式挡墙的高度方向预埋有若干个单向土工格栅，本发明中将灌注桩的桩基设置在与扶壁式挡墙的对应位置，使得载荷能够更好的传递到桩基础上，利用桩基承台解决抗倾覆稳定问题，并且承台直接作为扶壁式挡墙的底板，不再另设挡墙底板，避免挡墙底板与承台使用钢筋连接出现不稳固的问题，使结构更加可靠，而通过暗撑梁抵消水平荷载，保证结构抗滑移稳定性，增加了结构的安全储备。
