Description

Technical Field

[0001] The utility model relates to the technical field of the water permeability coefficient test of road bricks, and particularly relates to a device for testing the water permeability coefficient of road bricks. Background Art

[0002] A road brick is a paving material, which is mainly made of cement and aggregates, and is manufactured by processing, vibration pressing or other forming processes. Stripes or squares are cut and polished on the surface, and it is used for laying concrete pavements and ground projects such as sidewalks of urban roads and urban squares. Through its porous surface, natural precipitation can slowly penetrate into the underlying soil or be discharged through a drainage ditch. Existing road bricks need to be tested for their water permeability coefficient after production;

[0003] Application No. 202123041873.1 discloses a device for testing the water permeability coefficient of permeable road bricks, which includes a housing, a water tank, a water supply electric valve, a water level sensor, a permeable cylinder, an overflow water tank, an airbag and a bracket. The above device automatically controls the process of adding non-aerated water to the container through a water supply system; reduces the introduction of gas during the water addition process by closely fitting the water inlet pipe with the permeable cylinder; controls the water supply electric valve through the water level sensor, which opens when the water level is not reached and closes when the water level is reached, accurately controlling the water level in the permeable cylinder and avoiding unnecessary waste; realizes the sealing of the specimen by installing an airbag inside the permeable cylinder, bringing convenience to the test process. However, the products of existing road bricks after production and molding are basically rectangular block structures, while most of the existing test devices use round block structures as test objects, resulting in the need to use additional models for the production of test objects, which not only causes waste of resources but also consumes manpower.
