Foundation reinforcing method for freezing and thawing area of expressway
The invention discloses a method for reinforcing a foundation in a freezing and thawing area of an expressway, which comprises the following steps of: draining the foundation through a drainage assembly, the drainage assembly comprises a pair of longitudinal drainage grooves arranged below two road shoulders of a pavement layer, a pair of transverse drainage grooves arranged below two road shoulders of the pavement layer, and a pair of transverse drainage grooves arranged below two road shoulders of the pavement layer; the upper water collecting plate is arranged below the pavement layer; the lower water collecting plate is arranged below the upper water collecting plate; the transverse drainage grooves are formed below the two longitudinal ends of the lower water collecting plate. Accumulated water of the pavement layer can be rapidly discharged from the road shoulder side, accumulated water permeating into the lower portion of the pavement layer is rapidly discharged from top to bottom, erosion of rainwater to a highway foundation is reduced, and the highway pavement structure has high adaptability and improvement performance on the multi-year freezing and thawing cycle effect of freezing and thawing areas of the east highway.
本发明公开了一种高速公路冻融区地基加固方法，包括将地基排水，排水步骤是通过排水组件实现的，所述排水组件包括：一对纵向排水槽，其设置于路面层的两路肩下方；上集水板，其设置于路面层的下方；下集水板，其设置于所述上集水板的下方；一对横向排水槽，其设置于所述下集水板的纵向两端下方。本发明能够将路面层的积水快速由路肩侧排出，将渗入路面层下方的积水自上至下快速排出，降低雨水对高速公路地基的侵蚀，对高速东路冻融区多年冻融循环作用具有较强的适应性和改善性。
