Problems solved by technology

[0002] At present, ecological permeable pavement and its products have been widely used as new ecological and environmental protection materials at home and abroad, and because of the environmental protection and social benefits of ecological permeable pavement will be more and more applied, and will become the trend of outdoor road and floor promotion , in response to the rush of the market, various ecological permeable pavements and products are inevitably mixed up. For this reason, application specifications and standards are being compiled one after another in various places. However, when we analyzed these standards that are being compiled, we found that they all have the same problem: the determination of water permeability. The most critical performance of the pavement - water permeability coefficient has not yet been tested by a feasible and easy-to-operate testing instrument, either using a water seepage meter for asphalt pavement or using a core sampling method for testing, and the data are not operable and comparable

Embodiment Construction

[0040] Such as figure 1 , 2 In the specific embodiment shown, the water permeability tester consists of:

[0041] The graduated cylinder (1) is made of transparent plexiglass. The diameter of the graduated cylinder (1) is 70mm, and the volume is slightly larger than 2000ml. The graduated cylinder is marked with a uniform scale, and the resolution of the scale is 2ml. 2000ml is located at the lower end of the graduated cylinder;

[0042] The top plate (3) is circular with an outer diameter of 150 mm, and the top plate (3) has a central through hole with an inner diameter of 80 mm; the bottom of the measuring cylinder is threadedly connected to the top plate, and a sealing gasket is arranged at the bottom of the measuring cylinder to prevent water leakage;

[0043] The base (9) is a circle with an outer diameter of 150 mm, the base (9) has an opening with an inner diameter of 80 mm, and the base is provided with 3 exhaust holes;

[0044] There are three column supports (5), a...

Abstract

The invention relates to an instrument special for the field test or the nondestructive test of the permeability coefficient for ecological permeable roadways and permeable test blocks and a test method thereof. The instrument for testing the permeability coefficient of the invention comprises a measuring cylinder, a top plate, a base, an upright post bracket, a valve and a timing device, and can intuitively and fast test the permeability coefficient of the permeable roadways and permeable concrete test blocks without sampling drilled cores of the roadways. The instrument and the method for testing the permeability coefficient simulate the calculation of natural rainfall per unit area so that the test and calculation of the permeability coefficient of the permeable roadways are more practical and operable.

Description

technical field [0001] The invention relates to a special instrument for on-site testing or non-destructive testing of the water permeability coefficient of an ecological permeable pavement and a permeable test block and a testing method thereof.
