Drainage structure capable of prolonging service life of asphalt bridge floor and construction method of drainage structure
The invention discloses a device for enhancing drainage of a bridge deck structure and prolonging the service life of asphalt concrete, and solves the problem that the service life of the asphalt concrete is shortened due to water retention in a cement concrete pavement layer of a traditional bridge deck in the prior art. The device comprises a bamboo plywood with the thickness of 20 mm, square timber, a white PVC pipeline with the diameter of 20 mm, a nut, a clamp shaped like a Chinese character'shan ', a water stop piece, a U-shaped retention rib with the diameter of 25 mm, a square timber cushion block, polystyrene foam, permeable geotextile, a pull rod and a gasket. Nine holes are drilled in a bamboo plywood, pull rods penetrate through the bamboo plywood, the bottom ends of the pull rods are fixed through gaskets and nuts, water stop pieces penetrate through the other ends of the pull rods, the nine pull rods on the bamboo plywood with the thickness of 20 mm are sleeved with white PVC pipelines with the diameter of 20 mm, U-shaped retention ribs with the diameter of 25 mm are arranged on square timber cushion blocks, the pull rods are fixed through nuts and clamps shaped like a Chinese character'shan ', and polystyrene foam is injected into the white PVC pipelines with the diameter of 20 mm for sealing; and after construction of the cement concrete pavement layer of the bridge deck is completed, the polystyrene foam is removed, and the cement concrete pavement layer is filled with water-permeable geotextile, so that seepage water left on the cement concrete pavement layer of the bridge deck is discharged.
本发明公开了一种增强桥面结构排水延长沥青砼使用寿命的装置，解决了现有技术中传统桥面水泥混凝土铺装层内滞留水会使沥青混凝土寿命减少的问题，本发明包括20mm厚竹胶板、方木、Φ20mm白色PVC管道、螺帽、山型卡、止水片、Φ25mm U型固位筋、方木垫块、发泡胶、透水土工布、拉杆、垫片；在竹胶板上钻9个孔，将拉杆穿透竹胶板，底端用垫片和螺帽固定，另一端穿上止水片，将20mm厚竹胶板上的九根拉杆外套Φ20mm白色PVC管道，再将Φ25mm U型固位筋置于方木垫块上，用螺帽、山型卡将拉杆固定，在Φ20mm白色PVC管道内注入发泡胶进行封口；在桥面水泥混凝土铺装层施工完毕后将发泡胶清除并用透水土工布进行填塞，确保将滞留在水泥混凝土桥面铺装层的渗水排出。
