Mountain highway subgrade structure and construction method thereof
The invention discloses a mountainous area highway subgrade structure and a construction method thereof, and relates to the technical field of road construction, the mountainous area highway subgrade structure comprises a net surface reinforcing layer, a leveling layer and a pavement surface layer which are sequentially laid from bottom to top, and a plurality of anchor piles arranged in a subgrade, the anchor piles are used for being fixed in a rock stratum at the bottom of the subgrade, and the net surface reinforcing layer adopts a concrete structure; a plurality of pre-embedded steel bars are embedded in the net surface reinforcing layer, the pre-embedded steel bars are mutually bound and fixed, prestressed steel bars are pre-embedded in the anchor piles, the pre-embedded steel bars are fixedly connected with the prestressed steel bars, a bearing frame is embedded in the roadbed located on the road slope section, and a fixing mechanism used for fixing the bearing frame is fixedly arranged on the anchor piles. And the net surface reinforcing layer is lapped on the bearing frame. The stability of the roadbed of the road slope section can be effectively improved, the situation that when a rock-soil layer at the bottom of the road slope section collapses due to geological disasters, the bottom of the road collapses due to support losing is prevented, and long-term safe and stable operation of the road is guaranteed.
本申请公开了一种山区公路路基结构及其施工方法，涉及道路施工的技术领域，其包括从下到上依次铺设的网面加固层、找平层和路面表层，以及设置在路基内的若干锚桩，锚桩用于固定在路基底部的岩层内，网面加固层采用混凝土结构，且网面加固层内嵌设有若干预埋钢筋，各预埋钢筋相互绑扎固定，锚桩上预埋有预应力钢筋，预埋钢筋与预应力钢筋固定连接，位于道路边坡路段的路基内埋设有载承架，锚桩上固定设置有用于固定载承架的固定机构，网面加固层搭接在载承架上。本申请能够有效提升道路边坡路段路基的稳固性，防止因地质灾害导致道路边坡路段底部的岩土层发生塌陷时，道路底部因失去支撑而发生坍塌，确保道路长期安全稳定运行。
