Active drainage roadbed structure
The invention relates to the technical field of roadbed engineering, in particular to an active drainage roadbed structure which comprises a first soil filling layer, a first waste residue layer, a water absorption and drainage layer, a hydrophobic waterproof layer, a second soil filling layer and a second waste residue layer which are arranged from top to bottom, evaporators are arranged on the two sides of the water absorption and drainage layer, and each evaporator comprises a hollow shell, a partition plate and first water absorption geotextile. A scale-shaped opening is formed in the side wall of the outer side of the hollow shell, the partition plate is vertically arranged in the hollow shell, a plurality of vent holes are formed in the partition plate, the first water absorption geotextile is wound around the partition plate, a first drainage pipe with the interior communicated is arranged below the hollow shell, and drainage blind ditches are formed in the two sides from the hydrophobic waterproof layer to the second waste residue layer. The drainage blind ditch is connected with the evaporator through a first drainage pipe, and the bottom end of the drainage blind ditch is provided with a second drainage pipe communicated with a side ditch arranged outside the roadbed. The evaporators are arranged on the two sides of the water absorption and drainage layer, water in the water absorption and drainage layer can be evaporated, active drainage is achieved, and it can be guaranteed that water cannot be injected during direct rainfall.
本发明涉及路基工程技术领域，具体为一种主动排水路基结构，包括自上而下设置的第一填土层、第一废渣层、吸水排水层、疏水防水层、第二填土层、第二废渣层，吸水排水层两侧设有蒸发器，蒸发器包括空心壳体、隔板和第一吸水土工布，空心壳体外侧侧壁上设有鳞片状开口，隔板竖直设于空心壳体内，隔板上开设有多个通气孔，第一吸水土工布缠绕在隔板上，空心壳体下设有内部连通的第一排水管，疏水防水层至第二废渣层的两侧设有排水盲沟，排水盲沟通过第一排水管与蒸发器连接，排水盲沟底端设有第二排水管与路基外设置的边沟连通。本发明在吸水排水层两侧设置蒸发器，既可以蒸发吸水排水层内的水分，实现主动排水，还可以保证直接降雨时水分不会灌入。
