Prestressed cantilever type retaining wall structure and construction method thereof
The invention provides a prestressed cantilever type retaining wall structure and a construction method thereof, the prestressed cantilever type retaining wall structure comprises a vertical arm plate, a web plate, a toe plate and a heel plate, the web plate is arranged on the inner side of the vertical arm plate, a prestress applying device is arranged on the web plate, and a prestressed steel strand is preferably adopted, so that the vertical arm plate is initially in a compressive stress state. The cantilever type retaining wall has the beneficial effects that the webs are arranged on the inner side of the vertical arm plate of the cantilever type retaining wall at equal intervals, and the prestressed steel strands are arranged on the webs, so that the vertical arm plate of the retaining wall is initially in a compressive stress state. Compared with a traditional cantilever type retaining wall structure, the stress state of the structure can be remarkably improved through pressure stress provided by the prestressed steel strands, the characteristic that concrete is high in pressure resistance is fully utilized, meanwhile, structural reinforcements can be reduced, concrete cracking is prevented, and the application range and economical efficiency of the cantilever type retaining wall are increased.
本发明提供了一种预应力悬臂式挡墙结构及其施工方法，预应力悬臂式挡墙结构，包括立臂板、腹板、趾板和踵板，所述腹板设置在立臂板的内侧，腹板上设置有预应力施加装置，优选采用预应力钢绞线，使得立臂板初始处于受压应力状态。本发明的有益效果为：通过在悬臂式挡墙的立臂板内侧等距布置腹板，并在腹板上布置预应力钢绞线，从而使挡墙的立臂板初始处于受压应力状态。相对于传统悬臂式挡墙结构，通过预应力钢绞线提供的压应力，可显著改善结构的受力状态，充分利用混凝土抗压能力强的特点，同时可以降低结构配筋，预防混凝土开裂，增大悬臂式挡墙的适用范围和经济性。
