Road cutting slope karst cave filling and supporting structure and construction method
The highway cutting slope karst cave filling and supporting structure comprises a closed surface layer located on the opening face of a karst cave and a filling and supporting structure layer located in the karst cave. The filling supporting structure layer comprises a plurality of transverse structure ribs, longitudinal structure ribs, vertical structure ribs and filling balls, the transverse structure ribs and the longitudinal structure ribs are connected to form longitudinal and transverse meshes, and the vertical structure ribs are perpendicular to the longitudinal and transverse meshes and connected with the longitudinal and transverse meshes to form a plurality of three-dimensional grid spaces. A plurality of filling balls are mounted in the three-dimensional grid space, and each filling ball is connected with the adjacent transverse structural ribs, longitudinal structural ribs and vertical structural ribs; and concrete is poured in the residual space of the filling support structure layer. The invention further comprises a construction method of the highway cutting slope karst cave filling and supporting structure. The filling support structure provided by the invention is light in self weight, high in strength, compact in filling, simple in construction and low in cost.
公路路堑边坡溶洞填充支护结构，包括位于溶洞开口面的封闭面层以及位于溶洞内的填充支护结构层；所述填充支护结构层包括若干横向结构筋、纵向结构筋、竖向结构筋以及填充球，若干所述横向结构筋和纵向结构筋连接成纵横向网片，若干所述竖向结构筋垂直所述纵横向网片且连接所述纵横向网片形成若干立体网格空间，若干填充球安装在所述立体网格空间中，且每个填充球与相邻的所述横向结构筋、纵向结构筋和竖向结构筋分别相连；所述填充支护结构层的剩余空间浇筑有混凝土。本发明还包括所述公路路堑边坡溶洞填充支护结构的施工方法。本发明所提供的填充支护结构自重轻、强度高、填充密实、施工简单且成本低。
