Description

Technical Field

[0001] The utility model relates to the field of concrete permeameters, in particular to an expandable automatic pressurized concrete permeameter. Background Art

[0002] Concrete is an artificial stone material widely used in modern architecture. For hydraulic structures, underground buildings and some other construction projects, concrete structures are required to have anti-seepage properties. Anti-seepage properties refer to the performance of concrete in resisting the penetration of water or other liquid media under pressure. Concrete permeameter is an instrument used to measure the anti-seepage properties of waterproof sand. It can conduct comparative tests between recycled concrete mixed with waterproofing agent and benchmark concrete. However, in order to detect the structure more accurately, existing concrete permeameters often set up multiple test molds horizontally, which increases the product's footprint.

[0003] According to an automatic pressurized concrete permeameter provided by patent application number CN202122011737.1; the support frame is detachably connected to the chassis and is located above the first workbench, a second workbench is arranged on the support frame, one end of the first pipeline corresponds to the first water outlet, the other end of the first pipeline corresponds to the first test mold, one end of the second pipeline corresponds to the second water outlet, the other end of the second pipeline corresponds to the second test mold, the first test mold is installed on the first workbench, the first test mold is injected with water through the first pipeline, the second test mold is installed on the second workbench, the second test mold is injected with water through the second pipeline, so that the automatic pressurized concrete permeameter can carry out two sets of experiments at the same time, and because the second workbench is located above the first workbench, the floor space occupied by the automatic pressurized concrete permeameter is effectively reduced.

[0004] There are still some shortcomings in this patent application. Although this patent saves space, multiple concrete blocks need to be moved in and out during a sampling test. Manual switching is required after each concrete block is tested, which greatly affects the detection efficiency. Therefore, we propose an expandable automatic pressurized concrete permeameter to solve this problem. Utility Model Content
