A test device and method for quantitatively measuring the clogging state of permeable concrete pavement

Abstract

The invention discloses a test device for quantitatively measuring the blockage state of a water-permeable concrete pavement. The test device consists of a microwave detection conduction device, a vector network analysis instrument and a computer; and microwave reflected by a concrete layer enters the vector network analysis instrument through a data access line, the computer is connected with theoutput end of the vector network analysis instrument through a data output line, the computer is used for capturing phase information of a reflection coefficient, the porosity size of the concrete layer of the measured area is calculated, the defects in the prior art are overcome, the device and the method capable of quantitatively analyzing the blockage condition of the water-permeable concretepavement and having real-time nondestructive detection process are provided, and the problems that the blockage condition of the water-permeable concrete pavement cannot be evaluated quantitatively and the pavement is damaged when the core needs to be taken during detection are solved.

Description

technical field [0001] The invention relates to the field of permeable concrete structures and materials, and it solves the technical defects that currently it is impossible to quantitatively evaluate the blockage of permeable concrete pavement, and the detection requires coring to damage the pavement. Background technique [0002] As a high water permeability material, permeable concrete is applied to pavement materials, which provides great help to solve the problem of urban precipitation drainage and safe water storage; when using permeable concrete as pavement, slope protection or other projects, it can obtain Drainage, anti-slip, sound absorption, noise reduction, and water seepage effects can improve the ecological cycle of the surface, benefit driving traffic safety, protect the living environment, and solve the negative impact caused by large-scale modern urban construction. [0003] In recent years, with the introduction of the concept of "sponge city", pervious con...
