Description

Technical Field

[0001] This utility model relates to the field of infrared thermal imaging detection technology for anti-seepage walls, and more specifically, to an infrared thermal imaging detector for the quality of high-pressure jet grouting anti-seepage engineering projects for anti-seepage walls. Background Technology

[0002] Cutoff walls, due to their reliable structure, good seepage prevention effect, simple construction, and low cost, are often used to treat permeable foundations of dams, sluices, cofferdams, and dikes, and are also commonly used for the safety reinforcement of dilapidated earth dams. However, in actual construction, the stress state at the connection between the top of the cutoff wall and the surrounding soil is very complex. Infrared thermal imaging technology has evolved from laboratory thermodynamic theory to a core detection method in seepage prevention projects, essentially representing a technological evolution to meet the needs of "detecting hidden defects" and "comprehensive non-destructive assessment" of high-pressure jet grouting walls.

[0003] In the prior art, application number 201721714217.4 discloses a base for a miniature infrared thermal imaging detector, including a base, an outer box fixedly connected to the top of the base, and a pressure plate penetrating through the top of the outer box. A connecting plate is fixedly connected to one side of the pressure plate extending into the interior of the outer box, and a fixing plate is fixedly connected to the bottom of the connecting plate. Movable rods are movably connected to both sides of the bottom of the fixing plate, and sliding plates are fixedly connected to both sides of the bottom of the inner wall of the outer box. The above-mentioned device can only perform shock absorption for the infrared thermal imaging detector, which is not practical enough. It cannot flexibly adjust and position the infrared thermal imaging detector when performing infrared thermal imaging detection on a large area of ​​walls. Furthermore, when inspecting the quality of wall engineering projects, simply using an infrared thermal imaging detector will not allow the environment to affect the detection data.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In response to the problems in related technologies, this utility model proposes an infrared thermal imaging detector for the quality of high-pressure jet grouting anti-seepage engineering projects for anti-seepage walls, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

A level is fixedly connected to the bottom side of the adjusting bracket, and fixed blocks are fixedly connected to the left and right ends of the level. A positioning screw is threaded through the fixed block. The adjusting bracket includes an L-shaped support plate and a lifting horizontal plate.

[0015] The beneficial effects of this utility model are as follows: it allows for the quick assembly and fixation of a handheld infrared thermal imager onto an adjustable bracket, eliminating the need for personnel to hold the infrared thermal imager by hand. This effectively prevents handheld inspection from causing deviations in the alignment angle with the seepage barrier, thus affecting the inspection results.

Furthermore, it ensures that the inspection data is not affected by the external environment during the inspection process. Attached Figure Description
