Highway subgrade structure and construction method thereof
The invention discloses a highway subgrade structure and a construction method thereof, and belongs to the technical field of highway structures, wherein the highway subgrade structure comprises a hardened base layer, a prefabricated slab layer, a connecting layer, a gravel layer and an asphalt layer which are sequentially distributed from bottom to top; wherein the hardened base layer is formed by pouring concrete, and the upper surface of the hardened base layer is horizontally arranged; the prefabricated slab layer is formed by splicing a plurality of prefabricated parts, the cross section of each prefabricated part is in an inverted U shape, and a wavy steel plate fixing part is arranged in each prefabricated part; pressure detectors are fixed to the bottoms of the steel plate fixing pieces, and detection bases are connected to the bottoms of the pressure detectors and abut against the upper surface of the hardened base layer. The connecting layer is formed by laying a reinforcing mesh on the precast slab layer; the rubble layer is formed by paving rubbles on the top of the prefabricated slab layer, and concrete is poured between the rubble layer and the connecting layer; and the asphalt layer is formed by paving asphalt on the gravel layer. The highway subgrade structure has the effects of effectively monitoring the settlement condition of the ground where the highway subgrade structure is located and improving the safety.
本申请公开了一种公路路基结构及其施工方法，属于公路结构技术领域，其中，一种公路路基结构，包括由下至上依次分布的硬化基层、预制板层、连接层、碎石层以及沥青层；硬化基层由混凝土浇筑形成，且硬化基层上表面水平设置；预制板层由若干预制件拼接制成，预制件的横截面呈倒U形，且预制件内设有呈波浪形的钢板固定件；钢板固定件底部固定有压力检测器，压力检测器底部连接有检测座，检测座与硬化基层上表面相抵；连接层有钢筋网于预制板层上铺设形成；碎石层由碎石于预制板层顶部铺设形成，且碎石层与连接层之间浇筑有混凝土；沥青层由沥青于碎石层上铺设形成。本申请具有有效监测公路路基结构所在地面的沉降情况，提升安全性的效果。
