Problems solved by technology

The domestic measurement of the water permeability coefficient of permeable concrete is mainly based on the test method for water permeability coefficient of pavement in Appendix A of CCJJ/T135-2009 "Technical Regulations for Permeable Cement Concrete Pavements". The measurement steps of this method are relatively complicated and the accuracy is not high.
At present, the Chinese patent application publication number is 200820103220.7 permeable brick water permeability tester, said tester is composed of water supply container, fixed container, height-adjustable container, etc., the device is too complicated, and the permeable brick test block

Abstract

The invention discloses a device for measuring a permeability coefficient of concrete. The device comprises a water tank, a positioning water drum, a water outlet, a measuring drum, a telescopic water permeating support, a transparent cylinder with scales, a water overflowing opening, an upper water collection opening, a water pump and a water pipe, wherein the positioning water drum is positioned on the water tank; the water outlet is formed in the side face of the positioning water drum; the measuring drum is correspondingly arranged below the water outlet; the telescopic water permeating support is positioned in the positioning water drum and is used for holding a concrete test block; the transparent cylinder with scales sleeves the concrete test block; the water overflowing opening is formed in the side face of the transparent cylinder with scales; the upper water collection opening is formed in the part, corresponding to the water overflowing opening, on the water tank; the water tank is connected with the water pump; the water pump is connected with the water pipe to supply water to the transparent cylinder with scales. The device can measure both the permeability coefficient of a concrete varying head and the permeability coefficient of a concrete fixed head; meanwhile, the device is easy to assemble and disassemble and convenient to actually operate, and has energy-saving and environment-friendly effects since water can be recycled.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a concrete water permeability coefficient measuring device. Background technique [0002] my country has a large population, relatively poor and uneven water resources, and the development of modernization requires a large amount of groundwater. However, in order to meet the requirements of high strength and durability, most roads in China are paved with dense pavement, and the road surface is impermeable. Although It has brought great convenience to our life, but it will have many negative impacts on the ecological environment, mainly including that rainwater cannot penetrate the surface and return to groundwater, causing the groundwater level to decrease; when there is a heavy rain in the city, impermeable The road surface will accumulate a large amount of rainwater and cause urban flooding. It is also not conducive to the circulation of heat and moisture in the air, so the ...
