Roadbed steel corrugated pipe culvert jacking structure and jacking construction method
The invention discloses a roadbed steel corrugated pipe culvert jacking structure and a jacking construction method, the head of a steel corrugated pipe is connected with a steel wedge, and the steel wedge is in a shape with a thick upper part and a sharp lower part, so that the resistance of the head of the pipe culvert entering a cave is reduced in the construction process, meanwhile, the unbalanced stress of the pipe culvert caused by the gradient is reduced, and the construction quality is improved. The grouting pipes are installed on the outer side walls of the steel corrugated pipes, the overall rigidity of the steel corrugated pipe culvert can be improved through the grouting pipes, the grouting pipes on the adjacent steel corrugated pipes are connected through the grouting pipe connecting devices, after the steel corrugated pipe culvert enters a soil body, in the jacking process of the steel corrugated pipes, the grouting pipes can reduce the friction resistance between the culvert and the soil body through grouting, and therefore the overall rigidity of the steel corrugated pipe culvert is improved. And after construction is finished, the grouting pipe can conduct grouting through the grouting holes to fill gaps between corrugations and soil, and therefore the influence of the culvert on the road surface is reduced.
本发明公开了一种路基钢波纹管涵顶进结构及顶进施工方法，通过在钢波纹管头部连接钢楔，钢楔呈上粗下尖的形状，在施工过程中减小管涵头部进入洞穴的阻力，同时减少管涵由于坡度引起的不均衡受力，提高施工质量，钢波纹管外侧壁上安装有注浆管，注浆管可以增加钢波纹管涵的整体刚度，相邻钢波纹管上的注浆管通过注浆管连接装置连接，钢波纹管涵进入土体后，钢波纹管顶进过程中，注浆管可以通过注浆减小涵洞与土体之间的摩擦阻力，进而提高施工效率，施工结束后，注浆管还可以通过注浆孔进行注浆来填补波纹与土之间的空隙，从而减小涵洞对路面造成的影响。
