Description

Technical Field

[0001] This utility model relates to the technical field of concrete impermeability testing devices, and in particular to a permeability testing device for high-permeability concrete in basements. Background Technology

[0002] Basements are constantly exposed to a damp underground environment, making waterproofing crucial. Waterproofing testing devices can accurately detect the impermeability of highly impermeable concrete, identify potential leaks in advance, and prevent groundwater from seeping into the basement during use. This ensures the waterproofing of the basement structure and guarantees its normal use.

[0003] A search revealed Chinese Patent Publication No. CN115326671A, which discloses a device and method for testing the permeability of concrete, relating to the field of concrete testing. The device includes a body with a workbench fixedly connected to its top. A quick-installation mechanism is provided on the workbench, and a mold body is mounted on the quick-installation mechanism. The quick-installation mechanism includes a mold base, a limiting frame, a positioning block, and a driving assembly. The mold base is fixedly connected to the workbench, and the mold body is disposed on the mold base. The limiting frame is fixedly connected to the outside of the mold base. When the mold body needs to be installed, the concrete permeability testing device simply places it on the mold base. The outer ring rotates, and the inner ring rotates synchronously. The inner ring rotates while the lifting block cannot rotate due to the setting of the limit frame, causing the lifting block to rise. The rising lifting block flips the positioning block inward. During the flipping process of the positioning block, the positioning groove of the positioning block will first limit the mold body to the center. Then, as the positioning block continues to flip, the positioning block will press the mold body and the mold base together to fix it. However, the compatibility with existing equipment, test pieces or other components is not fully considered. For example, the design of the connection interface has a unique size or shape, which makes it difficult to adapt to test pieces of different specifications, or it cannot work in conjunction with other testing auxiliary equipment, which limits the versatility and application range of the equipment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a permeability testing device for high-permeability concrete in basements, aiming to improve the problem of difficulty in adapting to specimens of different specifications in the existing technology.
