Sponge city road
The invention discloses a sponge city road which comprises a surface layer, a permeable layer and an anti-seepage layer, the anti-seepage layer comprises an anti-seepage cushion layer and an anti-seepage structural layer, the anti-seepage cushion layer is a mixture of fine sand, straw biochar particles and fly ash, and the anti-seepage structural layer is a mixture of silty clay and straw biochar powder. The straw biochar particles in the sponge city road provided by the invention have impermeability, after the straw biochar particles are mixed with the fine sand and the fly ash, the layer is almost waterproof, the straw biochar, the fine sand and the fly ash are not damaged under the frost heaving effect, and the impermeability function is still not reduced under the load effect of passing vehicles; the silty clay in the anti-seepage structure layer has anti-seepage performance, and the anti-seepage layer cannot be damaged under the load effect of passing vehicles and the frost heaving effect, so that the problems of roadbed blockage, pavement damage and roadbed subsidence damage in the operation process can be avoided on the basis of low cost, and seepage can be accelerated.
本申请公开了一种海绵城市道路，包括面层、渗透层和防渗层，所述防渗层包括防渗垫层和防渗结构层，所述防渗垫层为细砂、秸秆生物炭颗粒和粉煤灰的混合物，所述防渗结构层为粉质粘土和秸秆生物炭粉的混合物。本发明提供的上述海绵城市道路中的秸秆生物炭颗粒具有防渗性，与细砂、粉煤灰混合后，该层几乎不透水，在冻胀作用下，秸秆生物炭、细砂和粉煤灰都不会发生破坏，在过往车辆的荷载作用下，防渗透性功能仍然不会降低，防渗结构层中的粉质粘土具有防渗性，这种防渗层在过往车辆的荷载作用下和冻胀作用下均不会被破坏，从而能在低成本的基础上，避免运行过程中出现路基堵塞、路面破损和路基沉陷破坏问题，且能够加速渗流。
