High-bearing-capacity road subgrade structure
The invention relates to the technical field of highway engineering, in particular to a high-bearing-capacity road subgrade structure which comprises a soft soil layer, a gravel layer and a surface layer which are sequentially arranged from bottom to top, and a water collecting device is arranged between the surface layer and the gravel layer. The water collecting device comprises a waterproof geotextile layer, a water collecting brick and a permeable geotextile layer which are sequentially arranged from bottom to top, a cavity used for collecting rainwater is formed in the water collecting brick, and a receding groove allowing the rainwater to pass through is formed in the side, close to the permeable geotextile layer, of the water collecting brick. The method has the effect of reducing the phenomenon of uneven settlement of the road.
本申请涉及公路工程的技术领域，尤其是涉及一种高承载道路路基结构，包括由下而上依次排布的软土层、砂石层和面层，所述面层和砂石层之间设置有集水装置，所述集水装置包括由下而上依次排布的不透水土工布层、集水砖和透水土工布层，所述集水砖内开设有用于对雨水进行收集的空腔，所述集水砖靠近透水土工布层的一侧开设有供雨水通过的让位槽。本申请具有减少道路发生不均匀沉降的现象的发生的效果。
