Construction process of anti-seepage drainage structure of road central green belt
The invention discloses a construction process of an anti-seepage drainage structure of a road central green belt. A protective layer is laid under the green belt. The protective layer includes anti-seepage geotextile, emulsified asphalt and cement mortar surfaces, and medium-coarse sand with upper water permeability geotextile and lower water permeability geotextile is further laid above a drainport, and the anti-seepage effect is good; and through a soft water permeable pipe, water falling into the green belt can be discharged into a rainwater well through a PVC pipe, the problems that thewater in the green belt invades into a roadbed base and causes damage to road foundations, and potholes and collapses to a pavement and the like are caused are solved, and the normal use of a road isensured.
本发明公开了一种道路中央绿化带防渗排水结构的施工工艺，在绿化带下方铺设了保护层，包括防渗土工布、乳化沥青以及水泥砂浆面，在排水口上方还铺设了带上下透水土工布的中粗砂，防渗效果好，落入绿化带中的水会通过软式透水管将水经过PVC管排入雨水井内，杜绝了绿化带内的水侵入路基基层，对道路基础造成破坏，导致路面出现坑洞及塌陷等问题，确保了道路的正常使用。
