Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel detection, and in particular relates to equipment for detecting water hazards behind the lining of an operating tunnel. Background Art

[0002] Due to the influence of geological conditions, topographic conditions, climatic conditions and various factors in the design, construction and operation process, tunnels will suffer from various diseases of varying degrees during long-term use after they are built. Some tunnels even suffer from relatively serious tunnel diseases in the early stage of use, such as structural water leakage, cavities behind the lining, lining cracks, insufficient lining thickness, base subsidence and bottom bulge, etc. Tunnel defects or diseases are a global problem, and tunnel structural diseases are common and prominent problems in today's railway, highway and subway projects.

[0003] According to the relevant regulations and statistical data on the classification of tunnel diseases in operation, tunnel diseases are mainly manifested in: tunnel water leakage, structural lining corrosion and cracking, and invert deformation and damage, accounting for more than 75% of tunnel diseases. Among these diseases, lining cracking and deformation and water leakage are more common in highway tunnels that have been in operation for 5 to 10 years.

[0004] At present, the method used by my country for the quality inspection of the lining of highway tunnels under construction or in use is mainly to use a handheld ground-penetrating radar antenna close to the tunnel wall to inspect the lining and integrity. Specifically, the method for lining inspection of tunnels under construction or in use is: the staff stands on a lifting vehicle, holding a ground-penetrating radar antenna, and makes the ground-penetrating radar antenna close to or in contact with the inner wall of the tunnel. Then, the lifting vehicle moves along the longitudinal section or survey line of the tunnel, so that the radar antenna can inspect the longitudinal section or survey line of the tunnel.

[0005] This detection method has the following main problems: for relatively long tunnels, only one tunnel survey line or one tunnel longitudinal section can be detected at a time. It takes a lot of time to complete the measurement of the entire section, and the efficiency is very low. In addition, since the staff stand at a high place for detection, there are great safety hazards. At the same time, this technology has good detection effects on cavities behind the lining, base voids, lining steel mesh and lining thickness, but it cannot effectively detect tunnel leakage and the existence of water behind the lining.

[0006] Based on this, the applicant considered designing an equipment for detecting water damage behind the lining of an operational tunnel. Utility Model Content

[0007] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a device for detecting water hazards behind the lining of an operating tunnel.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0009] A device for detecting water hazards behind the lining of an operating tunnel, comprising a mobile platform, an antenna frame and an antenna unit, wherein the antenna frame is in an arc shape and comprises a fixed end and a free end, wherein the fixed end is fixedly connected to the mobile platform, and the free end extends upward in an arc shape to above the mobile platform, and there are multiple antenna units, which are arranged in sequence on the antenna frame.

[0010] Compared with the prior art, the utility model of a device for detecting water damage behind the operating tunnel lining has the following advantages:

[0011] By setting up a mobile platform, antenna frame and antenna unit, it is possible to detect multiple tunnel measurement lines or multiple tunnel longitudinal sections at one time when inspecting longer tunnels, saving inspection time, improving inspection efficiency, and reducing the risk of falling caused by hand-held inspection by workers. At the same time, it can also effectively detect tunnel leakage and the existence of water behind the lining.

[0012] The above-mentioned equipment for detecting water hazards behind the lining of an operating tunnel has the advantages of simple structure and easy implementation. It is suitable for installation and use in existing tunnel inspection projects, and has a low cost of use, which can improve benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Compared with the prior art, the utility model of a device for detecting water damage behind the operating tunnel lining has the following advantages:

[0026] By setting up the mobile platform 100, antenna frame 200 and antenna unit 300, it is possible to detect multiple tunnel measurement lines or multiple tunnel longitudinal sections at one time when inspecting a longer tunnel, saving inspection time, improving inspection efficiency, and reducing the risk of falling caused by hand-held inspection by workers. At the same time, it can also effectively detect tunnel leakage and the existence of water behind the lining.

[0027] The above-mentioned equipment for detecting water hazards behind the lining of an operating tunnel has the advantages of simple structure and easy implementation. It is suitable for installation and use in existing tunnel inspection projects, and has a low cost of use, which can improve benefits.

[0028] In this embodiment, Figure 1 and Figure 2 As shown, an extension rod 400 is connected between the mobile platform 100 and the antenna frame 200 . One end of the extension rod 400 is fixedly mounted on the mobile platform 100 , and the other end is connected to the fixed end 210 of the antenna frame 200 .

[0029] In this way, by providing the extension rod 400, the fixed end 210 of the antenna frame 200 can be extended to the outside of the mobile platform 100, making it more convenient for the mobile platform 100 to travel along the tunnel and easier to maintain balance.

[0030] In this embodiment, Figure 1 and Figure 2 As shown, a host 500 is installed on the mobile platform 100, and a transient electromagnetic instrument is arranged in the host 500.

[0031] During implementation, the host 500 is electrically connected to the antenna unit 300 .

[0032] In this way, by setting up the host 500 and the transient electromagnetic instrument, the antenna unit 300 can transmit the transient electromagnetic signal generated by the transient electromagnetic instrument in the host 500.

[0033] In this embodiment, Figure 1 and Figure 2 As shown, a plurality of antenna wire frames 230 are arranged in sequence along the length direction on the antenna skeleton 200 , and the antenna unit 300 includes a plurality of antenna groups, and the plurality of antenna groups are arranged in the plurality of antenna wire frames 230 in a one-to-one correspondence.

[0034] In this way, by setting the antenna wire frame 230, the antenna groups can be arranged in an orderly manner in the antenna wire frame 230, so that the antenna groups can be arranged more neatly.

[0035] In this embodiment, Figure 1 and Figure 2 As shown, there are sixteen antenna wire frames 230 and sixteen antenna groups, and the sixteen antenna groups are arranged in the sixteen antenna wire frames 230 in a one-to-one correspondence.

[0036] In this way, setting up sixteen antenna wire frames 230 can better detect the tunnel lining and achieve better detection effect.

[0037] In this embodiment, Figure 1 and Figure 2 As shown, each antenna group includes a transmitting antenna and a receiving antenna, and the transmitting antenna and the receiving antenna are arranged in an antenna wire frame 230 with overlapping loops.

[0038] When implemented, both the transmitting antenna and the receiving antenna are miniature models.

[0039] In this way, by setting up the transmitting antenna and the receiving antenna, the antenna unit 300 can both transmit and receive signals, and the overlapping loop setting makes the combination of the transmitting antenna and the receiving antenna occupy a smaller volume.

[0040] In this embodiment, Figure 2 As shown, a telescopic rod 600 is connected between the mobile platform 100 and the antenna frame 200 . The telescopic rod 600 includes a positioning end 620 and a telescopic end 610 . The positioning end 620 is fixedly mounted on the mobile platform 100 , and the telescopic end 610 is connected to the fixed end 210 of the antenna frame 200 .

[0041] In this way, the position of the fixed end 210 of the antenna frame 200 relative to the mobile platform 100 can be adjusted, making it more adaptable.

[0042] In this embodiment, Figure 1 and Figure 2 As shown, a counterweight block 700 is also included. The counterweight block 700 is installed on the mobile platform 100 and is arranged opposite to the antenna frame 200.

[0043] During implementation, the counterweight 700 is installed on a side wall of the mobile platform 100 that is opposite to the antenna frame 200 .

[0044] In this way, the pressure exerted by the antenna frame 200 on the mobile platform 100 can be balanced by the counterweight block 700 through the counterweight block 700, thereby preventing the mobile platform 100 from tipping over during movement.

[0045] The above are only preferred implementations of the present invention. It should be pointed out that a number of modifications and improved technical solutions made by those skilled in the art without departing from the technical solution should also be deemed to fall within the scope of protection required by the claims.
