Urban tunnel drainage system based on sponge city concept
The invention discloses an urban tunnel drainage system based on a sponge city idea, a water seepage road section with a certain length is arranged at a tunnel portal, the water seepage road section comprises a water seepage surface layer, a water seepage base layer and a soil layer from top to bottom, the water seepage surface layer is formed by paving water seepage concrete containing diatomite and water seepage concrete containing fly ash, and the water seepage surface layer is formed by paving water seepage concrete containing diatomite and water seepage concrete containing fly ash. The permeable base layer is in contact with soil through coarse aggregate. Water can be conveniently discharged to a roadbed and is not affected by capillarity to rise, the permeation rate can be effectively increased, and the problems that a traditional concrete gap structure is difficult to control and prone to blockage are solved. The problems of difficult drainage and easy water accumulation at the entrance of the urban underpass tunnel are solved in combination with a sponge urban drainage system, the problem of later disease recurrence can be avoided, and the treatment method is high in operability, safe and reliable and has good economic benefits.
本发明公开了一种基于海绵城市理念的城市隧道排水系统，在隧道口设置一定长度的渗水路段，透水路段包括自上而下的透水面层、透水基层和土壤层，透水面层采用使用含硅藻土的透水混凝土和含粉煤灰的透水混凝土铺设而成，透水基层采用粗骨料与土壤接触。方便将水排放到路基的同时使得水不受毛细现象影响上升，可有效增大渗透速率，解决传统混凝土空隙结构控制难，易堵塞问题。结合海绵城市排水系统解决城市下穿式隧道洞口处排水难易积水问题，可避免后期病害复发的问题，且处治方法操作性强，安全可靠，具有较好的经济效益。
