道桥工程建设促使着交通事业的全面发展。在车流量的不断增长下,对于道桥的压力也是越来越大。道桥建设质量与磨损程度有直接的关系,通过车辆的反复通行,加上阳光的暴晒,雨水的侵蚀,冻害等,使道桥在一定程度上出现了负荷问题。而出现负荷问题最重要的原因就是雨水的沉积,造成路面不平。积洼、裂缝。地基沉陷等问题的产生。因此在道桥施工中,尤其要注意的就是防水施工,以提升路桥的质量、延长其使用寿命。
Road construction project to promote the all-round development of transport. Under the continuous traffic growth, the pressure on the bridge is also increasing. The quality of bridge construction has a direct relationship with the degree of wear. Through the repetitive passage of vehicles, exposure to sunshine, rain erosion and frost damage, the bridge has a load problem to a certain extent. The most important cause of load problems is the deposition of rainwater, resulting in uneven road. Puddles, cracks. Subsidence and other issues arising. Therefore, in the construction of the bridge, with particular attention to waterproof construction, in order to enhance the quality of road and bridge, to extend its service life.
