Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a road concrete compression resistance detection device. Background Art

[0002] Road concrete is a building material composed of cement, aggregate, sand, and water mixed in a specific proportion. It is an essential component of road and bridge construction and significantly impacts their quality. Concrete boasts simple processing, safety, and reliable stability, but its construction demands exceptionally high technical standards. After construction, concrete's compressive strength must be tested to ensure the road's longevity and quality.

[0003] At present, traditional detection devices are usually only capable of performing detection at local locations when conducting road detection, which reduces the comprehensiveness of the detection. In addition, during the detection process, it is inconvenient to operate, which reduces the convenience of the detection operation.

[0004] For example, a device for testing the compressive strength of concrete for road bridges disclosed in Chinese patent CN216117113U includes a U-shaped frame, a movable groove is provided inside the U-shaped frame, a driving assembly is provided inside the movable groove, a driving end of the driving assembly is fixedly connected to a testing assembly, a spirit level is fixedly connected to the front of the U-shaped frame, and a control box is fixedly connected to one side of the U-shaped frame. The utility model facilitates the staff to understand the balance of the installation of the testing device through the provision of the spirit level, thereby improving the accuracy of subsequent compressive strength testing, and through the provision of the testing assembly, the condition of the bottom surface of the road bridge when it is subjected to high-intensity pressure can be quickly determined, thereby completing the compressive strength test, and through the provision of the driving assembly, the testing assembly can be driven to move left and right, facilitating the compressive strength testing function at different positions, thereby improving the comprehensiveness of the test.

[0005] However, the device only has one detection device and does not have the function of multi-point detection. When conducting detection in a large range and multiple locations, the speed is slow and labor-intensive.

[0006] To this end, we proposed a road concrete compression resistance detection device to solve the above problems. Utility Model Content
