为提升透水网格承载能力,砖体下方常采用水泥硬化措施,造成铺装渗透性下降,为解决该问题,在透水网格中添加了碎石渗井.碎石渗井因截留外来环境中的颗粒物导致渗井-透水网格渗透性能下降.研究了不同类型堵塞物对碎石渗井堵塞的影响规律,并通过改变碎石粒径的方式对碎石渗井的构造进行了优化.结果表明,碎石粒径会影响其抗堵塞性能,当粒径为 20～30 mm 时,碎石渗井在堵塞影响下可以保持较好的渗透能力.
Experimental Study on the Effect of Clogging on the Permeability Performance of Gravel Seepage Wells
To enhance the bearing capacity of permeable pavers,cement hardening measures are often used below the brick,resulting in a decline in permeability.To solve this problem,permeable pavers with stone infiltration wells were added.The stone infiltration wells have a decreased permeability due to the retention of particulate matter from the external environment.The influence of different types of blockages on the clogging of stone infiltration wells was studied,and the structure of the stone infiltration wells was optimized by changing the grain size of the stone.The results show that the grain size of the stone affects its resistance to clogging.When the grain size is from 20 mm to 30 mm,the stone infiltra-tion well can maintain good permeability under the influence of clogging.
