Super-thick soft highway subgrade reinforcing device and construction method thereof
The invention discloses an ultra-thick soft highway subgrade reinforcing device. The device comprises a lower reinforcing layer; the multiple anti-freezing assemblies are arranged in the length direction of the road, any anti-freezing assembly comprises a ground source heat pump, a heat supply pipe loop and a heat exchange pipe loop, and the heat exchange pipe loop communicates with the heat supply pipe loop through the ground source heat pump; the upper reinforcing layer comprises a metal-based composite particle layer, a thermal insulation layer and a pavement layer which are sequentially arranged from bottom to top; the drainage assembly comprises a plurality of drainage pipes, a pair of drainage inclined pipes and a water storage tank, the two ends of the drainage pipes are communicated to the pair of drainage inclined pipes respectively, and the bottoms of the drainage inclined pipes are provided with connection pipes communicated to the water storage tank; any drainage pipe is connected to one row of extending steel bar joints and provided with a plurality of rows of drainage blind pipes extending into the roadbed. The problem of seasonal frozen soil diseases of the ultra-thick soft highway subgrade is fundamentally solved, the strength of the ultra-thick soft highway subgrade is enhanced, and the driving load requirement of the ultra-thick soft highway subgrade is met.
本发明公开了一种超厚软公路路基加固装置，包括：下加固层；多个防冻害组件，其沿公路长度方向设置，任一防冻害组件包括地源热泵、供热管回路以及热交换管回路，所述热交换管回路和供热管回路通过所述地源热泵连通；上加固层，其包括自下而上依次设置的金属基复合颗粒层、保温层和路面层；排水组件，其包括多个排水管、一对排水斜管和蓄水箱，多个排水管两端分别连通至一对排水斜管，所述排水斜管底部设有连通至蓄水箱的联系管；任一排水管连接至一排延伸钢筋节上，且任一排水管上设有多排伸入路基的排水盲管。本发明从根本上解决超厚软公路路基季节性冻土病害问题，加强了超厚软公路路基的强度，保证了超厚软公路路基行车荷载的需求。
