前言在地下水位高而且丰富的平坦地带修建道路的立体交叉,往往位于立交下部的道路需要下挖形成路堑引道,这时便会遇到地下水的处理问题。对于地下水的处理,以往多采用槽沟、渗沟、渗水隧洞……等,以引出排除地下水为目的的建筑结构。随着科技事业的飞速发展和四个现代化的要求,对某些因特殊原因不允许降低地下水位以及引走排出地下水的地区的工程,采用对工程封闭地下水的措施就显得格外重要了。封闭式路堑是一种由边墙和底板组成的结构,它与框构桥(或涵)构成为一个整体,将
Introduction Three-dimensional intersections in roads with high groundwater levels and rich flat areas often need to be dug to form a cutting edge road at the lower part of the interchange. In this case, groundwater disposal problems will be encountered. For the treatment of groundwater, in the past more use of trenches, infiltration ditch, seepage tunnel ... ..., in order to lead to exclude groundwater for the purpose of the building structure. With the rapid development of science and technology and the requirements of the four modernizations, it is especially important for some projects to close underground water works for projects that for certain special reasons do not allow to lower the water table and lead to the discharge of groundwater. Closed cut is a structure composed of side walls and floor, which is framed with the bridge (or culvert) as a whole, the
