我国的所有道路桥梁在施工设计时都考虑到防水的问题,但是随着道路桥梁使用时间的延长,路面出现了许多裂痕,经过车辆反复辗压的地段出现路面松散和褶皱的现象,有的路面遭到严重的损坏。在桥梁道路建设中防水和排水的设计和建设非常重要,保证了道路桥梁不被雨水腐朽所引起的质量问题。目前我国的道路桥梁防水技术取得了一定的成绩,但也存在不少问题。本文根据我国道路桥梁建设的发展情况对桥梁建设的防水材料、科学合理的桥梁道路建设结构和相关法律的保护措施等进行了分析,以促进桥梁道路防水技术的发展。 All roads and bridges in our country are designed with waterproofing in mind. However, with the prolongation of the use of road and bridge, there are many cracks in the road surface. Loose and wrinkled roads appear in the areas repeatedly rolling. Some pavements Serious damage. It is very important to design and construct the waterproofing and drainage in the construction of bridge roads and ensure the quality of the roads and bridges not being damaged by the rainwater. At present, China’s road and bridge waterproof technology has made some achievements, but there are still many problems. Based on the development of road and bridge construction in our country, this paper analyzes the waterproofing materials for bridge construction, the scientific and reasonable bridge road construction structure and the protection measures of related laws, in order to promote the development of bridge waterproofing technology.
