Permeable brick permeability coefficient measuring device

Abstract

The invention discloses a permeable brick permeability coefficient measuring device. The permeable brick permeability coefficient measuring device comprises an overflow water tank, a water permeable cylinder and a water permeable brick body, a plurality of supporting columns are fixedly connected to a bottom plate of the overflow water tank. A first overflow pipe is inserted into the side wall ofthe overflow water tank; the overflow water tank is communicated with the outside through the first overflow pipe; a first measuring cylinder is placed under the end, located outside the overflow water tank, of the first overflow pipe, an L-shaped supporting plate is connected to the outer side wall of the overflow water tank, a fixing support is connected to the lower end of the vertical sectionof the L-shaped supporting plate, and the fixing support is fixed to a foundation through fixing screws. According to the measuring device, water permeable cylinder and the water permeable brick bodyare arranged in a separated mode, so that the effect of convenient operation can be achieved when the water permeable brick body is taken and placed, the water permeable brick body can be convenientlyreplaced by adopting a separated mounting structure, and thus the effect of high-efficiency work can be achieved when different water permeable brick bodies are measured.

Description

technical field [0001] The invention relates to the technical field of measuring equipment for permeable bricks, in particular to a measuring device for the permeability coefficient of permeable bricks Background technique [0002] In recent years, permeable pavements have become one of the most commonly used low-impact development techniques. Low-impact development techniques include structural layers and relatively high porosity that allow stormwater to pass through its surface and underlying layers, including permeable pavement surfaces, total sub-base, sometimes including geotextiles and underdrains, and eventually infiltrate into natural soil or into drainage systems. [0003] The two main advantages of the permeable brick paving system are good hydrological effects and reduced stormwater pollution. A significant environmental benefit of the hydrological effect is to reduce the amount of rainwater runoff and groundwater recharge, which requires that the PPS must have s...

Problems solved by technology

[0007] When researching permeable bricks, the placement of permeable bricks has the problem that it is not easy to take. Moreover, when placing permeable bricks, it is easy to cause impact on the bottom of the measuring equipment. Since there is no protective device on the measuring equipment, it is easy to cause equipment damage. damage
