Expressway roadbed anti-settlement device

The utility model discloses an expressway roadbed anti-settlement device which comprises a bearing plate and an extrusion pile, the extrusion pile is welded at the lower end of the bearing plate, and reinforcing inserting rods are symmetrically arranged on the lower end face of the bearing plate. The extrusion piles, the reinforcing inserting rods and the transverse inserting rods are inserted into the roadbed, the bearing plate can be evenly stressed, settlement caused by uneven stress of the roadbed is avoided, meanwhile, the extrusion piles are pressed into the roadbed to increase the strength of the roadbed, and the white lime absorbs water in the roadbed, so that settlement of the roadbed can be well avoided. 本实用新型公开了一种高速公路路基防沉降装置，包括：承载板与挤压桩，所述挤压桩焊接在承载板的下端，所述承载板下端面对称设置有加强插杆。本实用新型通过将挤压桩、加强插杆及横向插杆插入路基内部，能够使承载板受力均匀避免路基因受力不均导致的沉降，同时挤压桩压入路基增加路基的强度，以及白石灰吸收路基内部的水分，以此能够很好的避免路基沉降。
