Half-roadbed and half-tunnel road structure and construction method thereof
The invention is applicable to the technical field of tunnel engineering, and provides a half-roadbed and half-tunnel road structure and a construction method thereof. The road structure comprises a tunnel, a retaining wall and a cutting. The cutting, the retaining wall and the tunnel are sequentially arranged in the uphill direction of the current ground. The cross section of the tunnel is in a "C" shape, and the "C"-shaped opening extending towards the retaining wall in the longitudinal direction of the tunnel. The retaining wall blocks a tunnel opening and is connected with the top wall andthe bottom wall of the tunnel opening, and a row of circular holes are arranged at certain intervals at the middle-upper of the retaining wall in the longitudinal direction of the road, and are usedfor lighting and ventilation of the tunnel. Therefore, the cost of the tunnel in the operation stage is reduced. The half-roadbed and half-tunnel road structure solves the problem on road design and construction at the edge of steep slopes, and has good environmental effect, high safety in the operation stage and low operation cost; the construction method has small earthwork quantity, saves construction time, improves construction efficiency, and is worthy of wide popularization.
本发明适用于隧道工程技术领域，提供了一种半幅路基半幅隧道的道路结构及其施工方法。该道路结构包括隧道、挡墙以及路堑。所述路堑、挡墙以及隧道沿现状地面上坡方向依次排列。隧道横断面呈“C”形，沿暗挖隧道纵向延伸的“C”形开口朝向挡墙；挡墙封堵隧道开口，并与隧道开口的顶壁以及底壁连接，沿道路纵向在挡墙中上部位置按一定间距设置一排圆形孔，用于隧道采光、通风，以降低隧道运营阶段成本。本发明提供的半幅路基半幅隧道的道路结构解决了位于陡坡边缘的道路设计施工问题，环境效应好，运营阶段安全性高，运营成本低；本发明的施工方法，土方工程量小，节省了施工成体，提高了施工效率，值得大范围推广。
