Bridge subgrade waterproof and drainage structure
The invention relates to the field of bridge subgrade surface waterproofing, and particularly discloses a bridge subgrade surface waterproof and drainage structure which comprises a drainage channel, a drainage layer and a waterproof layer. The drainage channels are arranged on the two sides of the bridge subgrade face in a downwards-inclined mode. The drainage layer comprises a supporting steel frame, a lower stone layer, a disordered wire plastic layer, an upper stone layer, a road surface layer, a confluence water channel and isolation plates, the isolation plates are vertically arranged and evenly distributed in the length direction of the bridge roadbed surface, every two adjacent isolation plates form a drainage space, the supporting steel frame is arranged in the drainage space, and the lower stone layer is laid at the bottom of the supporting steel frame; the entangled plastic layer is laid at the upper end of the lower stone layer, the upper stone layer is laid above the entangled plastic layer, the pavement layer is arranged above the upper stone layer, the confluence water channels are arranged on the two sides of the bridge roadbed surface and communicated with all the drainage spaces, the confluence water channels are communicated with the drainage channel, and the upper portion of the drainage channel extends to the position above the pavement layer. The lower part of the drainage channel is flush with the bottom of the confluence water channel; the waterproof layer is arranged at the upper end of the pavement layer.
本发明涉及桥梁路基面防水领域，具体公开了桥梁路基面防排水结构，包括排水道、排水层和防水层；排水道向下倾斜设置在桥梁路基面的两侧；排水层包括支撑钢架、下石子层、乱丝塑料层、上石子层、路面层、汇流水道、隔离板，隔离板竖直设置且沿桥梁路基面的长度方向均匀排布，相邻两个隔离板形成排水空间，支撑钢架设置在排水空间中，下石子层铺设在支撑钢架的底部，乱丝塑料层铺设在下石子层的上端，所述上石子层铺设在乱丝塑料层的上方，路面层设置在上石子层的上方，汇流水道设置在桥梁路基面的两侧并与所有排水空间连通，汇流水道与排水道连通，排水道的上部延伸到路面层的上方，排水道的下部与汇流水道的底部齐平；防水层设置在路面层的上端。
