Highway roadbed structure capable of preventing roadbed softening
The invention discloses an expressway subgrade structure capable of preventing subgrade softening, and relates to the technical field of expressways, the expressway subgrade structure comprises a base body, the base body comprises a rammed earth layer, a bedding layer, a water stabilizing layer, a concrete layer and an asphalt layer, the rammed earth layer, the bedding layer, the water stabilizing layer, the concrete layer and the asphalt layer are sequentially arranged from bottom to top, the bedding layer is laid on the top of the rammed earth layer, and the water stabilizing layer is laid on the top of the asphalt layer. And the bedding layer is matched with the rammed earth layer. According to the invention, the water filtering property of the roadbed is improved through the bedding layer and the water stabilizing layer, and then the collected accumulated water is discharged through the water collecting tank and the water collecting pipe, so that the drainage speed in the soil base layer is increased, the viscosity loss caused by excessive water in the soil layer is avoided, and the soil and the accumulated water can be quickly separated in rainy seasons; therefore, the highway roadbed softening problem is prevented, the highway is prevented from having problems, the blocking net in the water catchment groove blocks soil flowing down along with accumulated water, and the situation that drainage is affected due to the fact that the soil enters a pipeline and the pipeline is blocked is prevented.
本发明公开了可防路基软化的高速公路路基结构，涉及高速公路技术领域，包括基体，所述基体包括夯土层、铺垫层、水稳层、混凝土层、沥青层，所述夯土层、铺垫层、水稳层、混凝土层、沥青层从下到上依次设置，所述夯土层顶部铺设有铺垫层，所述铺垫层与夯土层相适配。本发明中，通过铺垫层与水稳层提高路基的滤水性，再通过汇水槽与集水管将汇集的积水排出，使得泥土基层内部排水的速度增快，避免泥土层水分过多而失去黏性，在雨季时能够使泥土与积水迅速分离，从而实现了对高速公路路基软化问题的防治，避免了高速公路出现问题，汇水槽中的阻隔网将随着积水流下的泥土进行阻隔，防止泥土进入管道导致管道堵塞从而影响排水。
