Permeable interlocking concrete paver lot performance quantification for short-term installation and maintenance concerns

混凝土摊铺机是一种受欢迎的硬质美化产品，因为它们可以创造出诱人的表面，而且耐用。 越来越多的摊铺机不仅用于美观，而且在设计上具有渗透性，并允许 雨水渗入下层土壤。透水性联锁混凝土摊铺机(PICP)是一种现场施工 精心设计的雨水管理系统。工地层面的雨水管理控制可以缓解洪水 恢复自然过程，如渗透和提供雨水的分布式储存，可能会带来风险。在……里面 为了确保PICP的长期功能，需要解决与安装程序相关的问题，并 制定定义明确的标准和指南。随着时间的推移，PICP失去了渗透雨水的能力 地面洞口逐渐被泥沙堵塞。具有成本效益的维护实践以恢复活力 地表入渗能力仍有待开发。在这个项目中，加拿大砖石设计中心将 将175平方米的现有人行道改建为PICP。试验路面将被用来调查 PICP雨水滞留时间对雨水水量控制的影响 施工后的第一次同花顺以及施工后第一个冬天的表现。三人被拘留 将测试以下做法：(1)自由释放，(2)24小时拘留，(3)48小时拘留。结果 这项研究的内容将被纳入CMDC将制定的安装和操作标准草案中。

Concrete pavers are a popular hardscaping product as they create attractive surfaces and are long-lasting. Increasingly pavers are being used for more than just aesthetics but are design to be permeable and allow for rainwater to infiltrate into underlying soils. Permeable interlocking concrete pavers (PICP) are an on-site engineered stormwater management system. Site level stormwater management controls can mitigate flooding risks by restoring naturalized processes such as infiltration and providing distributed storage of stormwater. In order to ensure the long-term functionality of PICP there is a need to address installer related issues and to develop well defined standards and guidelines. Over time PICP losses its ability to infiltrate stormwater as surface openings gradually become clogged with sediment. Cost effective maintenance practices to rejuvenate surface infiltration capacity still need to be developed. In this project the Canada Masonry Design Centre will convert 175 sqm of existing walkways to PICP. The experimental pavement will be used to investigate the the impact of stormwater detention time for PICP on quantity control of stormwater, water quality concerns from the 'first flush' after construction as well as performance in the first winter after construction. Three detention practices will be tested: (1) free release, (2) twenty-four hour detention, (3) forty-eight hour detention. Results of this research will be integrated into draft installation and operation standards to be developed by CMDC.
