Description

Technical Field

[0001] The utility model relates to the field of permeable bricks, in particular to an experimental device for detecting and comparing the water permeability of permeable bricks. Background Art

[0002] With the development of the economy, the country pays more and more attention to urban ecological construction, and the slogan of building a "sponge city" has also emerged. The core of building a sponge city is permeable bricks, which allow rainwater to pass through the bricks and collect in the underground canal, and then drain into the river. Permeable bricks are new green and environmentally friendly building materials. The raw materials are mostly environmentally friendly materials such as cement, sand, slag, fly ash, etc., and they are not formed by high-temperature firing. They are formed in one step by dry pressing. They have good permeability, strong anti-slip function, natural and durable color, various colors and shapes, and are in harmony with the surrounding environment. Natural and beautiful. When selecting permeable bricks, comparative experiments such as permeability and compression resistance are required to select suitable permeable bricks to meet actual application needs. Regarding water permeability, the traditional detection method is mainly through visual observation by pouring water, which is a relatively rough process and leads to large comparison errors. There are various existing detection devices, but some can only detect one piece at a time, and it takes a long time to detect multiple pieces. Although some can detect multiple pieces at a time (such as patent CN116539495A), when the number of bricks is large, multiple batches of detection are still required, and the operation process of changing different batches is relatively troublesome.

Rainwater falls on the permeable bricks and enters the temporary water storage area 8 through the permeable bricks. Since the first water tank 1 and the second water tank 6 are both transparent water tanks, the water permeability of the permeable bricks with different structures can be observed intuitively, and the water permeability within a certain period of time can be recorded by observing the water level in the temporary water storage area 8.

Such an arrangement improves the sealing performance of the temporary water storage area.
