Problems solved by technology

However, when bentonite particles meet water, they will enter the pores of the permeable bricks through the openings on the inner ring, causing pore blockage, which in turn affects the determination of the permeability coefficient, and is not conducive to the recycling of permeable bricks, resulting in waste

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. The examples are used to explain the present invention, but not to limit the protection scope of the present invention.

[0024] 1. Test device for measuring permeability coefficient of ceramic permeable bricks

[0025] see figure 1 , The device for measuring the permeability coefficient of ceramic permeable bricks provided by the present invention includes a test box, a support base 8 and an outflow tank 13 . The test box includes upper and lower parts connected as one by connecting flange 9. Compared with stainless steel, plexiglass is lighter and cheaper, and the transparency of plexiglass is more convenient for real-time observation of the penetration test process. Therefore, the test The box is made of 10mm thick plexiglass.

[0026] The lower half of described test case comprises support seat 8 and sample groove 5 (cross section can be ...

Abstract

The invention discloses a porous ceramic water permeable brick permeability coefficient determination device and method. The determination device comprises a test box, the upper part of the test box is provided with a water inlet and an overflow port, and the test box is arranged in an outflow water tank. The outflow water tank is connected with the test box, and a water outlet is formed in the upper part of the outlet water tank. A ceramic water permeable brick sample is placed in the lower part of the test box, the gap between the ceramic water permeable brick sample and the side wall of thetest box is tightly filled with an inflated and tensioned electric vehicle inner tube, water can be prevented from leaking along the side wall of the test box during permeability coefficient measurement, the measurement process of the permeability coefficient of the ceramic water permeable brick is simplified, and an accurate permeability coefficient measurement result is obtained.

Description

technical field [0001] The invention relates to the measurement of the permeability coefficient of pavement pavement materials, in particular to a device and method for measuring the permeability coefficient of porous ceramic permeable bricks. Background technique [0002] With the acceleration of urbanization, the area of ​​impermeable pavement is also increasing year by year. Impervious pavement prevents surface runoff from rainfall from infiltrating into the ground, leading to environmental problems such as urban waterlogging, groundwater shortage, and heat island effect that affect people's lives. In order to alleviate and solve these environmental problems, permeable pavement came into being. Permeable pavement is a high-permeability pavement structure, which plays an important role in the construction of sponge cities and is widely used. At present, the common permeable pavement materials mainly include permeable concrete, permeable asphalt mixture and ceramic permeab...
