Expressway medial strip sinking water cut-off system
The invention provides an expressway medial strip sinking water cut-off system. The expressway medial strip sinking water cut-off system comprises an expressway roadbed and a medial strip arranged in the middle of the roadbed in the longitudinal direction of the roadbed. The medial strip comprises concrete cutoff walls, a waterproof concrete layer, a drainage layer and a greening layer, the two concrete cutoff walls are symmetrically arranged on the two side walls of the medial strip and define a separation groove, the waterproof concrete layer is arranged at the bottom of the separation groove, the drainage layer is arranged between the waterproof concrete layer and the greening layer, and the greening layer extends out of the road surface; a transverse pipeline arranged in the transverse direction of the roadbed is arranged in the roadbed, one end of the transverse pipeline is communicated with the drainage layer, the other end of the transverse pipeline sequentially penetrates through the concrete cutoff wall and the roadbed to extend out of the side slope of the roadbed, and the transverse pipeline is used for discharging water which is not absorbed by the greening layer out of the roadbed. According to the scheme, accumulated water can be prevented from infiltrating to be concentrated towards the low concave position, the potential slip surface slip sinking risk of the medial strip is reduced, and therefore the bearing capacity of the roadbed pavement is guaranteed.
本发明提供了一种高速公路中央分隔带下沉断水系统，包括高速公路的路基以及沿路基纵向方向设于路基中间的中央分隔带；中央分隔带包括混凝土隔水墙、防水混凝土层、排水层以及绿化层，两面混凝土隔水墙对称设于中央分隔带两侧壁并围设形成分隔槽，防水混凝土层设于分隔槽底部，排水层设于防水混凝土层与绿化层之间，绿化层伸出于路面；路基内设有沿路基横向方向设置的横向管道，横向管道的一端连通排水层，横向管道的另一端依次穿过混凝土隔水墙以及路基以伸出路基的边坡，横向管道用于将绿化层未吸收水排出路基。本方案可阻止积水下渗向低凹处集中，降低中央分隔带潜在滑移面滑移下沉风险，从而保证路基路面的承载能力。
