Coastal plain area municipal road roadbed waterproof isolation protection structure and construction method
The invention relates to a coastal plain area municipal road roadbed waterproof isolation protection structure and a construction method. Sealing ditches are built on two sides of a roadbed; each sealing ditch is excavated to a certain depth below a underground impermeable soil layer; and sealing films are laid at bottoms of the sealing ditches and on side slopes, and the sealing ditches are filled with limestone soil so that the roadbed is isolated from peripheral permeable soil, underground water is prevented from invading the roadbed to damage a pavement structure, and various diseases suchas pavement collapse and cracking caused by underground water erosion can be reduced.
本发明涉及一种沿海平原地区市政道路路基防水隔离保护结构及施工方法，主要是通过在路基两侧修筑密封沟，密封沟开挖至地下不透水土层以下一定深度，密封沟沟底及边坡上铺设密封膜，密封沟内回填石灰土，从而将路基与周边透水土体进行隔离，阻止地下水侵入路基进而引起路面结构的破坏，可减少因地下水侵蚀造成路面塌陷、开裂等各种病害。
