Filling construction method for steel corrugated pipe culvert in highway fill subgrade
The invention discloses a filling construction method for a steel corrugated pipe culvert in a highway fill subgrade, and belongs to the technical field of damage treatment of a culvert structure under a fill subgrade. The method comprises the steps of excavating a foundation trench, laying a bottom cushion layer, performing filling of layered step-type cement soil layers, laying a sand-gravel cushion layer, installing the steel corrugated pipe culvert, pouring a mortar consolidation body, performing filling of covering soil and the like. By the adoption of the construction method, the two sides of the steel corrugated pipe culvert can be filled with a cement soil material with high rigidity and strength within a certain range, and dense filling is facilitated, so that the rigidity of thecement soil is utilized to limit the deformation of the pipe culvert, the purposes of reducing the deformation of the steel corrugated pipe culvert and reducing stress concentration are achieved, andpotential safety hazards are eliminated.
本发明公开了一种公路填方路基中钢波纹管涵填土施工方法，属于填方路基下涵洞结构病害处理技术领域，包括挖掘基槽、铺设底部垫层、填筑分层台阶式水泥土层、铺设砂石垫层、安装钢波纹管涵、灌注砂浆固结体、填筑覆土等步骤，采用本发明的施工方法，钢波纹管涵两侧一定范围内可填筑刚度及强度较大的水泥土材料，且便于填充密实，从而利用水泥土的刚度限制管涵的变形，达到减小钢波纹管涵变形和减小应力集中的目的，消除安全隐患。
