摘要:
针对陶瓷透水砖在应用中广泛存在的堵塞问题，利用自行研发的透水砖雨水径流堵塞实时模拟装置，分别采用自来水和模拟雨水，进行透水砖堵塞试验以及应用3种清洁方式恢复透水砖透水性能试验。在相同径流水量和径流水深条件下，透水砖堵塞主要归结于雨水径流中的颗粒物质在砖表面和内部被截留。堵塞过程分为快速堵塞、回升波动和平稳堵塞3个阶段。根据颗粒物质进入透水砖内部的位置，堵塞可分为表面堵塞和内部堵塞。透水砖表面截留的颗粒质量大于内部截留量，被截留的大部分颗粒粒径<50 μm。负压反冲洗、高压水枪冲洗、表面清扫对透水砖透水系数的恢复率分别为76.80%、46.43%、40.52%，三者基本均能完全去除透水砖表面截留颗粒，但后两者无法去除透水砖内部截留颗粒，因此推荐采用负压反冲洗方式控制陶瓷透水砖堵塞。
Abstract:
To solve the widespread clogging problems of permeable ceramic brick in application, experiments on clogging and recovery of permeable ceramic brick by three cleaning methods were carried out in a self-developed real-time simulation device for clogging of permeable brick by using tap water and simulated runoff. Under the same runoff discharge and water depth, the clogging of permeable brick was mainly attributed to the interception of particles in rainwater runoff on the surface and inside of the brick. The clogging process could be divided into three stages: rapid clogging, fluctuation and stable clogging. The clogging could be classified into surface clogging and internal clogging according to the position of particles entering into the permeable brick. The intercepted particles on the surface were more than those inside the permeable brick, and the particle size of most intercepted particles was less than 50 μm. The recovery rates of the permeability coefficient of the permeable brick by vacuum cleaning, high-pressure gun flushing and surface sweeping were 76.80%, 46.43% and 40.52%, respectively. The intercepted particles on the brick surface could be completely removed by the three methods. However, the latter two could not remove the intercepted particles inside the brick. Therefore, the vacuum cleaning was recommended to control the clogging of the permeable ceramic brick.
