Urban permeable road water retention and drainage construction method and system
The invention provides an urban permeable road water retention and drainage construction method. The construction method comprises the following steps of S1, performing surveying and paying off; S2, paving an impermeable base layer on a roadbed, arranging slopes towards two sides from the center of the impermeable base layer, excavating blind ditches in two sides of the impermeable base layer, andmounting water permeable concrete plates between the impermeable base layer and the blind ditches; S3, laying a water-retaining sponge body module prefabricated from peat ash, diatomite and wood fiber water pervious concrete on the impermeable base layer to form a water absorption surface layer, and finally laying a water pervious surface layer on the water absorption surface layer; S4, excavating a plurality of water collecting wells in the blind ditches, and installing water permeable pipes on the blind ditches to connect the water collecting wells; S5, laying a gravel layer, a broken stonelayer and a soil layer sequentially on each water permeable pipe from bottom to top, and planting vegetation on the soil layer. The invention further provides an urban permeable road water retentionand drainage system. Compared with the prior art, road drainage and water retention can be achieved, meanwhile, the drainage capacity is improved, and road water accumulation is avoided.
本发明提供了一种城市透水道路保水排水的施工方法，其包括以下步骤：S1测量放线：S2在路基上铺设不透水基层，并在不透水基层中心朝向两侧分别设置有斜坡，在不透水基层的两侧开挖盲沟，并在不透水基层和盲沟之间安装透水混泥土板；S3在不透水基层上铺设由泥煤灰、硅藻土、木质纤维透水混凝土预制的保水海绵体模块，形成吸水面层，最后在吸水面层上铺设透水面层；S4在盲沟上开挖多个集水井，在盲沟上安装透水管将集水井相连接；S5在透水管从下到上依次铺设有砂砾层、碎石层和泥土层，并在泥土层上种植植被。本发明还提供了一种城市透水道路保水排水系统。本发明相较于现有技术可以实现道路排水保水的同时，提高其排水能力，避免道路积水。
