Description

Technical Field

[0001] The utility model belongs to the technical field of load box detection, in particular to a detection device for the load box's own bearing capacity. Background Art

[0002] As we all know, the load box is a special loading device used for pile foundation bearing capacity testing in the construction industry. The usual load box generally uses an ordinary oil cylinder (piston or plunger type) as the working unit. The main use is to fix two steel rings to the upper and lower ends of the load box respectively, put them into the pile hole, pour concrete, and then start the load box to generate upper and lower separation forces. After there are no problems, concrete is injected again to fill the gap, and the use is completed. The operation before use is very troublesome (mainly refers to the welding and fixing process). If there is a problem with the load box, a huge waste of manpower will occur. Therefore, it is very necessary to design a detection device before the load box is used.

[0003] The publication number is CN209894468U, which is a device for detecting the self-bearing capacity of a load box. A plurality of support rods are arranged on a mounting frame, and pressure plates are connected below the plurality of support rods. A pressure sensor is arranged on the mounting frame, and a display screen is arranged on the mounting seat. The pressure sensor and the display screen are connected via a transmission line. However, the device can only detect the load box during use, but still cannot detect the load box before use. Utility Model Content
