The invention relates to an expressway roadbed widening and grouting method. The method comprises the steps that a widened new roadbed is determined on the side face of an original roadbed; a new roadbed foundation is arranged below the determined new roadbed, and a new roadbed is arranged on the side face of the original roadbed and above the new roadbed foundation; arranging a step connecting structure at the junction of the original roadbed and the new roadbed, and fixing the original roadbed and the new roadbed from the side surface of the original roadbed based on the step structure; and after the original subgrade and the new subgrade are fixed, the new subgrade foundation and the new subgrade are fixed in the vertical direction. According to the scheme, by adopting the highway roadbed broadening grouting method, the broadened new roadbed part of the highway can have enough high strength and is not prone to sedimentation, the highway structure is more stable, the strength of combination of the original roadbed and the new roadbed is higher, structural deformation and damage are effectively prevented, and the service life of the highway is prolonged. And the normal service life of the expressway is effectively prolonged.
本发明涉及一种高速公路路基拓宽注浆方法，包括：在原路基侧面确定加宽的新路基；在确定的新路基下方设置新路基地基，并在原路基的侧面和新路基地基的上方设置新路基；在原路基与新路基结合处设置台阶连接结构，基于台阶结构从原路基侧面固定原路基与新路基；固定原路基与新路基后，沿着竖直方向固定新路基地基与新路基。根据本发明的方案，采用本发明的高速公路路基拓宽注浆方法，能够使得高速公路拓宽的新路基部分具有足够高的强度，不易发生沉降，使得公路结构更加稳定，原路基与新路基结合的强度更高，有效防止结构变形和损坏，有效提高高速公路正常的使用寿命。
