Problems solved by technology

[0006] The above-mentioned tester has a complex structure, a large number of parts, and difficult assembly between the parts, and the poor sealing between the parts leads to inaccurate measurement data. The measuring cylinder 2' and the top plate 3' are only connected by threads, which will lead to the failure of the entire tester. Poor stability and easy to fall
In addition, when operating the above-mentioned tester for testing, the operation requirements are relatively h...

Embodiment Construction

[0027] refer to Figure 1-3 As shown, a permeable concrete water permeability tester includes a base 1, a measuring cylinder 2, a first sealing ring 3, a second sealing ring 4, a bracket 5, and a counterweight ring 6. The base 1 has an upper opening 11, a middle cylinder 12 and a chassis 13, the outer diameters of the upper opening 11 and the middle cylinder 12 are equal, the inner diameter of the upper opening 11 is greater than the inner diameter of the middle cylinder 12, and the upper The inner diameter of the opening 11 is greater than or equal to the outer diameter of the measuring cylinder 2 , and the outer diameter of the chassis 13 is greater than the outer diameters of the upper opening 11 and the middle cylinder 12 .

[0028] see again figure 1 , the measuring cylinder 2 is inserted in the upper port 11 and fits with the top 121 of the middle cylinder 12, and the inner diameter of the measuring cylinder 2 is equal to the inner diameter of the middle cylinder 12, s...

Abstract

The invention provides a test method for the permeation coefficient of permeable concrete. A base, a measuring cylinder, a support frame and a first sealing ring are adopted for forming a permeation coefficient test instrument of the permeable concrete, the test method for the permeation coefficient of the permeable concrete comprises the step of installing the test instrument onto the ground to be tested, the step of recording the water level scale H1 at the beginning of the timing and the water level scale H2 at the end of the timing and the step of finally calculating the permeation coefficient. The method has the advantages that the structure is simple, the components are simplified, the stability is high, the sealing performance among all components is good, the measurement results have small error and high precision, the result calculation is simplified, in addition, the operation is simple and convenient, and the non-damage test can be carried out in any position in site.

Description

【Technical field】 [0001] The invention relates to a method for measuring ecological permeable pavement, in particular to a method for testing the water permeability coefficient of permeable concrete. 【Background technique】 [0002] The surface of modern cities is mostly covered by reinforced concrete buildings and impermeable pavement. Compared with natural soil, ordinary concrete pavement lacks breathability and has poor ability to absorb heat and penetrate rainwater, thus bringing a series of problems. Concrete has always been considered the culprit of the destruction of nature. But as long as the continuous pores are formed, the connection point between the concrete pavement and the natural environment can be created. Because of its honeycomb porous structure, permeable concrete is an opportunity to restore the earth's environment that is constantly being destroyed. It has characteristics different from ordinary concrete: small bulk density, insignificant water capillary...
