Permeable reconstruction technology based on existing roadbed
The invention relates to the technical field of municipal engineering, and particularly relates to a permeable reconstruction technology based on an existing roadbed layer. The technology comprises the steps of removing a surface layer and a leveling layer of an impermeable pavement to expose the existing roadbed layer; constructing a drainage pipe from the existing roadbed layer to the existing cushion layer on the existing roadbed layer; constructing a water storage tank in the existing roadbed layer, and enabling the water storage tank to be communicated with the drainage pipe; and sequentially laying a permeable leveling layer and a permeable surface layer on the surface of the reconstructed existing roadbed layer. Firstly, the drainage pipe and the water storage tank are constructed on the existing roadbed layer, so that the existing roadbed layer has a rainwater infiltration function, disassembly and reconstruction of the existing roadbed layer and the existing cushion layer areomitted; and meanwhile, due to the arrangement of the water storage tank, the flood discharge effect of an upper structure can be improved. By means of the permeable reconstruction technology, the problems that when a permeable structure is newly built, large-scale construction waste is generated due to large-scale disassembly and large-scale construction, and a large number of building materialsneed to be put into the permeable structure again at the same time are solved.
本发明涉及市政工程技术领域，尤其是涉及一种基于既有道路基层透水改造技术，包括以下步骤：拆除不透水路面的面层和找平层，露出既有路基层；在所述既有路基层上构建自所述既有路基层至既有垫层的排水管；在所述既有路基层中构建储水箱，并使所述储水箱与所述排水管连通；在改造后的所述既有路基层表面依次铺设透水找平层和透水面层。首先，在既有路基层上构建排水管及储水箱，使既有路基层具备雨水下渗功能，免去了对既有路基层和既有垫层的拆除和重建，与此同时，储水箱的设置可增大上部结构的泄洪作用。本发明的透水改造技术解决了透水结构新建时，面临大拆大建、产生大量建筑垃圾，同时需要重新投入大量建筑材料的问题。
