Expressway roadbed structure capable of preventing roadbed softening
The invention discloses an expressway roadbed structure capable of preventing roadbed softening. The expressway roadbed structure comprises a bottom layer; a first reinforcing layer which comprises afirst reinforcing net laid on the bottom layer and a cement mortar layer formed by pouring cement mortar on the first reinforcing net; an anti-softening layer which comprises a fixed grid net, a composite water filtering layer and a water outlet pipe; a second reinforcing layer; and a pavement layer which is arranged above the second reinforcing layer and comprises a base layer and a surface layerfrom bottom to top. The fixed grid net is connected with the first reinforcing net through supporting columns on the first reinforcing net; the composite water filtering layer is sequentially composed of a water guiding block, a coarse sand layer and a fine sand layer from bottom to top; and the water outlet pipe comprises branch water outlet pipes connected to the water filtering holes of the water guide blocks and a main water outlet pipe for communicating the branch water outlet pipes and extending out of the roadbed from the side surface of the roadbed. Through roadbed construction of a multi-layer structure, the strength of the roadbed is improved, meanwhile, high drainage performance is achieved, and roadbed softening is effectively avoided.
本发明公开了一种可防路基软化的高速公路路基结构，包括：底层；第一加固层，其包括铺设在底层上的第一加固网和将水泥砂浆浇筑在第一加固网上形成的水泥砂浆层；防软化层，其包括固定格栅网、复合滤水层和出水管；固定格栅网通过第一加固网上的支撑柱与第一加固网连接；复合滤水层由下至上依次由导水块、粗砂层和细砂层组成；出水管包括连接于各个导水块的滤水孔的分支出水管和将各个分支出水管连通的主出水管，主出水管由路基的侧面伸出路基外部；第二加固层；路面层，其设置在第二加固层上方；路面层由下至上包括基层和面层。其通过多层结构的路基建设，使得路基不仅强度增加，同时具有良好的排水性能，有效的避免了路基软化。
