摘要:
透水砖是海绵城市系统的重要组成部分，可有效降低城市雨洪风险。但透水砖会因截留颗粒物而降低其渗透性能，严重缩短其使用寿命。综述了透水砖的分类、堵塞机理、防堵控制技术，及其在我国的工程实践应用情况。透水砖堵塞位置和程度主要受材料、孔隙结构、雨水径流颗粒物性质及暴露环境等诸多因素共同影响，需要经常性的维护清理以保证其透水性能。目前，透水砖主要有人工清扫、高压冲洗和真空抽吸等三种维护方法，但只能去除透水材料表层截留物，恢复能力有限。因此，研制高强度和高渗透性的透水砖，以及与纳米科技应用和耦合系统有助于源头控制堵塞。最后对缓堵型透水材料研制和长效维护机制提出了研究建议。
Abstract:
Permeable bricks are important parts of the sponge city system that can be used to effectively reduce the urban flood risk. However, the permeability of permeable bricks will decrease by particles blocking, which will severely shorten the service life. This paper reviews the classification of permeable bricks, blocking mechanism，anti-blocking control technologies and application of engineering practice in China. The location and degree of permeable bricks blockage are mainly affected by many factors such as materials, pore structure, particulate matter of rainwater runoff and exposed environment. Regular maintenance is required to ensure the permeating performance of permeable bricks, three maintenance methods of manual sweeping, pressure washing and vacuum sweeping are currently used. But only the surface sediments of the permeable material can be removed, which caused limited recovery capacity. The development of high-strength and high-permeability permeable bricks, nanotechnology applications and coupling systems are needed for the control of blockage from the source. Research suggestions are given from the perspectives of slow?blocking permeable bricks and long-term maintenance systems.
