Roadbed slope protection system and construction method thereof
The invention discloses a roadbed slope protection system and a construction method thereof. The system comprises a flow guide seat and a drainage channel which are arranged at a slope toe, and a frame, a foundation pillar, a drainage channel, a pointed skeleton and a straight skeleton which are arranged on a slope, the diversion seat is positioned between the bottom edge of the slope and the drainage channel; a cushion layer and a waterproof layer are sequentially arranged on the drainage channel; the frame is laid on a slope and longitudinally divides the slope into a plurality of cells, the foundation columns are distributed in the cells in a rectangular array mode, the lower portions of the foundation columns extend into a soil body, the upper ends of the foundation columns are exposed, the drainage ditches are distributed in the cells, and the upper ends and the lower ends of the drainage ditches extend to the slope top and the flow guide base respectively. The pointed-end frameworks and the straight frameworks are prefabricated parts and are distributed in the cells, the pointed-end frameworks are in an inverted-V shape, the inner sides of the lower portions of the two sides of each pointed-end framework are clamped on the corresponding foundation pillar through arc-shaped grooves, the outer sides of the two sides extend to a nearby frame or drainage ditch, and the straight frameworks are installed at the lower ends of the two sides of each pointed-end framework in an inserted mode and fixed through post-pouring at the inserted positions. And the outer side edge is in contact with a nearby frame or drainage ditch. The structure can adapt to various soil properties, roadbed instability caused by rain wash can be avoided, the problems of slope collapse, roadbed settlement and the like are effectively relieved, and the driving safety risk is reduced.
本发明公开一种路基边坡防护系统及其施工方法，该系统包括设在坡脚处的导流座和排水渠以及设在边坡上的边框、基柱、排水沟、尖头骨架和直骨架；导流座位于边坡底边和排水渠之间，排水渠上依次设有垫层和防水层；边框铺在坡面上且将坡面纵向分隔成若干个单元格，基柱呈矩形阵列分布在单元格内且下部伸入土体、上端露出，排水沟分布在单元格内且上下端分别延伸至坡顶和导流座；尖头骨架和直骨架为预制件且分布在单元格内，尖头骨架呈倒V形，其两边下部内侧通过弧形槽分别卡放在基柱上、两边外侧延伸至附近的边框或排水沟，直骨架分别插接安装在尖头骨架两边下端且插接处后浇固定，其外侧边接触附近的边框或排水沟。本发明能适应多种土质、能避免雨水冲刷导致路基不稳，有效缓解了边坡滑塌、路基沉降等问题，降低了行车安全风险。
