为了建造能够进行实测的混凝土路面砖透水路面和沉砂池渗水能力的测试场地,一家混凝土路面砖制造商、一家水泥制造商和Storm Aqua公司合作,在2014年开始一项专项研究。本研究项目包括四块测试场地。为测量和评价混凝土路面砖透水路面的透水性能和稳定性,首先建造两块经受重型和频繁交通荷载的测试路面。路面面层材料为缝隙透水混凝土路面砖,保证雨水渗入路基内。路面上多余雨水汇集在一起流入沉砂池,在沉砂池测量流入的水量。由此评价路面的透水能力。为向试验场地提供地表径流雨水,专门建造一个停车场作为测试路面。该测试场地所接受的径流水量,来自面积为其自身面积13倍的区域。建设这块试验场地的目的是:确定透水路面在不同降雨量条件下的实际渗透能力。建造一块混凝土路面砖透水路面示范试验区,通过现场演示和视频,能够直观地展示出混凝土路面砖透水路面的真实使用效果。在该示范试验区,可人为模拟不同降雨强度和透水路面的渗透效果。对安装在试验场内传感器所传输的数据,进行连续记录,并记录所对应的气象参数。由此就能够确定在不同气候条件下,路面渗透能力和其它参数。此外,还可以确定由于路面磨损、灰尘进入和生物生长等,所造成路面渗透能力随时间的变化情况。无法通过透水路面下渗的多余水,将被导入沉砂池和减量池,以便以后再渗透到地下。在这里用于确定地下基础设施的渗透能力。整个研究项目的测试区域建造于2014年~2015年期间,从2015年5月开始进行实测。该研究项目所产生和文件化记录数据,可作为计算路面渗透能力的参数。计算结果不仅可在挪威应用、也可在国外应用,可直接应用于未来对路面应采取什么样透水措施的方案制定,通过路面渗透方式来处理地表多余的雨水。
In order to build a test site capable of measuring the water seepage capacity of concrete paver bricks and grit tanks, a concrete paver, a cement manufacturer and Storm Aqua Corporation, started a special study in 2014. This research project includes four test sites. In order to measure and evaluate the water permeability and stability of the permeable pavement of concrete pavers, two test pavements subjected to heavy-duty and frequent traffic loads were first constructed. Pavement material for the gap permeable concrete pavement brick to ensure that rainwater infiltration subgrade. The excess rainwater collected on the road flows into the grit chamber and measures the inflow of water in the grit chamber. Thus, the water permeability of the road surface was evaluated. In order to provide surface runoff to the test site, a parking lot was specially constructed for testing the road surface. The amount of runoff received at this test site comes from areas that are 13 times their own area. The purpose of building this test site is to determine the actual permeability of a permeable pavement under different rainfall conditions. Construction of a concrete pavement brick permeable pavement demonstration test area, through live demonstrations and video, can visually demonstrate the real use of concrete Pavement Bricks pervious to water. In this pilot area, the infiltration effects of different rainfall intensities and permeable pavement can be artificially simulated. The data transmitted by the sensors installed in the test site shall be continuously recorded and the corresponding meteorological parameters shall be recorded. From this it is possible to determine the pavement penetration and other parameters under different climatic conditions. In addition, it is also possible to determine how pavement penetration changes over time due to road wear, dust ingress, and biological growth. The excess water that can not penetrate through the permeable pavement will be introduced into the grit chamber and the reduction pool for further infiltration into the ground. Used here to determine the infiltration capacity of underground infrastructures. The test area of the entire research project was constructed from 2014 to 2015 and the measurement was carried out from May 2015 onwards. The data generated and documented by this research project can be used as a parameter to calculate the permeability of pavement. The calculation result can be applied not only in Norway but also abroad. It can be directly applied to the scheme of what kind of water-permeable measures should be taken on the road surface in the future, and the excess rainwater on the ground should be dealt with through the road surface infiltration method.
