Highway subgrade widening structure and widening grouting method
The invention relates to the field of roadbed widening, in particular to a highway roadbed widening structure and a widening grouting method.The highway roadbed widening structure comprises an old roadbed and a new roadbed which are spliced with each other, the splicing position between the old roadbed and the new roadbed is in a step shape, the new roadbed is provided with a plurality of grouting pipes, and the grouting pipes are vertically inserted into the new roadbed and a soil layer located below the new roadbed; a first injection block is fixedly installed at the bottom end of the grouting pipe, a plurality of grout outlets are formed in a pipe body of the grouting pipe, second injection blocks are arranged at the grout outlets in a sliding and penetrating mode, the first injection block and the second injection blocks are conical, the second injection blocks are provided with driving mechanisms, and the driving mechanisms are used for driving the second injection blocks to go in and out of the grout outlets. The subgrade structure has the effect of reducing the situation of differential settlement between the new subgrade and the old subgrade.
本申请涉及路基拓宽的领域，尤其是涉及一种公路路基拓宽结构及拓宽注浆方法，其包括相互拼接的旧路基和新路基，旧路基和新路基之间的拼接处呈阶梯状，新路基设置有多根注浆管，注浆管竖直插入新路基和位于新路基下方的土层，注浆管的底端固定安装有第一贯入块，注浆管的管身开设有多个出浆口，出浆口滑移穿设有第二贯入块，第一贯入块和第二贯入块均呈锥形，第二贯入块安装有驱动机构，驱动机构用于驱动第二贯入块进出出浆口。本申请具有降低新路基和旧路基之间不均匀沉降的情况出现的效果。
