Construction method for filling high-fill roadbed of mountain road
The invention relates to the technical field of road construction, in particular to a mountainous area highway high fill roadbed filling construction method. Comprising preparation work before construction; the roadbed base is compacted before filling; filling a roadbed; the stone-filled roadbed comprises the steps of base treatment, side slope stacking and building, layered filling and layered rolling compaction. The roadbed is reinforced and compacted, specifically, a high embankment with the fill slope height larger than or equal to 20 m and an embankment with the half-filled and half-excavated fill slope height larger than 8 m are subjected to rolling reinforcement through an impact rolling or tonnage increasing road roller; filling soil and stones in a mixed manner; slope engineering, specifically, slope arrangement retaining and reinforcing engineering is conducted; subgrade settlement observation is conducted, and stability monitoring is conducted on an embankment with the slope height larger than 20 m or the ground slope rate larger than 1: 2.5, a half-filled and half-excavated embankment, a retaining wall road section and an embankment with potential stability hazards to the embankment through a foundation. According to the method, the safety and stability of the high-fill embankment of the mountainous highway are improved.
本申请涉及道路施工技术领域，尤其涉及一种山区公路高填方路基填筑施工方法。包括施工前准备工作；填前路基基地压实处理工作；路基填方；填石路基，包括基底处理、边坡码砌、分层填筑、分层碾压；路基补强压实，对填方边坡高度≥20m的高路堤和半填半挖填方边坡高度大于8m的路堤，采用冲击碾压或加大吨位压路机进行碾压补强；土石混填；边坡工程，边坡设置支挡加固工程；路基沉降观测，对于边坡高度超过20m的路堤或地面斜坡率陡于1:2.5的路堤，以及半填半挖路堤、挡土墙路段，地基对路堤存在稳定隐患的路堤，进行稳定性监控。该方法提高了山区公路高填方路堤的安全和稳定性。
