Construction structure for constructing road on soft soil foundation

XIAO LIANGWEN / LI LIXIAN / LI WENBIN

The invention relates to a construction structure for constructing a road on a soft soil foundation. The construction structure comprises a soft soil layer and a reinforcing column assembly partiallyinserted into the soft soil layer; the reinforcing column assembly comprises a plurality of reinforcing columns with hollow structures, and each reinforcing column is sequentially provided with a water inlet section, a reinforcing section, a drainage section and a connecting section from bottom to top; a first concrete layer is arranged at the top of the soft soil layer; a drainage layer is arranged at the top of the first concrete layer; a second concrete layer is arranged at the top of the drainage layer; each water inlet section is located in the soft soil layer; each reinforcing section islocated in the first concrete layer; each drainage section is located in the drainage layer; and each connecting section is positioned in the second concrete layer. By means of vertical drainage of the reinforcing columns, the soil body consolidation drainage distance can be shortened, the bearing capacity of the foundation is improved, the effect of reinforcing soft soil is achieved, the bearingcapacity and strength of the soft soil foundation can be effectively improved through the first concrete layer and the second concrete layer, and then the stability of the soft soil foundation is improved.

本申请涉及一种在软土地基上构建道路的施工结构，其包括软土层和部分插设于所述软土层中的加强柱组件，所述加强柱组件包括多根呈中空结构的加强柱，所述加强柱从下往上依次设有进水段、加固段、排水段以及连接段，所述软土层的顶部设置有第一混凝土层，所述第一混凝土层的顶部设置有排水层，所述排水层的顶部设置有第二混凝土层，所述进水段位于软土层中，所述加固段位于第一混凝土层中，所述排水段位于排水层中，所述连接段位于第二混凝土层中。本申请的加强柱的竖向排水可以缩小土体固结排水距离，提高地基承载能力，起到加固软土的作用，第一混凝土层和第二混凝土层可以有效提高软土地基的承载能力和强度，进而提高软土地基的稳定性。
