Description

Technical Field

[0001] This application belongs to the technical field of highway maintenance equipment, and in particular relates to a tunnel side-mounted culvert blockage monitoring pipe. Background Technology

[0002] As a crucial component of highways, the smoothness of a tunnel's drainage system directly impacts its structural stability, driving quality, and driver safety. The internal drainage system of a tunnel mainly consists of circumferential drainage pipes, transverse water guide pipes, and side-mounted drainage ditches. However, due to the limited size of these side-mounted drainage ditches and the influence of trace elements in groundwater, they are prone to forming crystals such as calcium carbonate and magnesium carbonate at water accumulation points. This reduces the effective cross-sectional area of ​​the ditch, causing blockage and weakening its water-carrying capacity, leading to road seepage and road surface uplift. Currently, side-mounted drainage ditches are designed with two layers of leak-proof covers at the top, making it difficult for maintenance personnel to inspect them during routine patrols. They can only destructively lift the covers, which is extremely inconvenient and inefficient. Furthermore, conventional pipeline inspection robots are difficult to widely adopt due to the limited space within the side-mounted drainage ditches (for example, the Guihe Expressway Daping Tunnel measures 35cm × 50cm) and their high cost. Summary of the Invention

[0003] The purpose of this application is to overcome the shortcomings of the prior art and provide a tunnel side-mounted culvert blockage observation pipe, which can establish long-term observation points, avoid the drawbacks of destructively opening the cover plate in traditional maintenance, and achieve non-destructive testing.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A tunnel side-mounted culvert blockage monitoring pipe includes a monitoring pipe fixedly connected to a cover plate of the side-mounted culvert; the monitoring pipe is a transparent monitoring pipe with one end open and the other end closed; a transparent graduated scale is fixedly installed on the side wall of the monitoring pipe; a transparent sealing cap is detachably installed at the open end of the monitoring pipe; an insertion port is provided on the cover plate, and the closed end of the monitoring pipe extends into the bottom of the side-mounted culvert through the insertion port.

[0006] In one embodiment, the observation tube is 60-80 cm long and 5 cm in diameter.

[0007] In one embodiment, the open end of the observation tube is 5 cm from the upper surface of the cover plate.

[0008] In one embodiment, the observation tube includes a transparent tube body and a circular base fixedly disposed at one end of the transparent tube body, wherein the circular base is fixed to the bottom of the transparent tube body by adhesive bonding.

[0009] In one embodiment, the observation tube is an acrylic round tube, a PC round tube, or a PVC round tube.

[0010] Positive effects:

[0011] 1. Non-destructive testing: Establish long-term observation points to avoid the drawbacks of destructively opening the cover in traditional maintenance, and realize non-destructive testing. Attached Figure Description

[0016] The specific implementation of this application is further described below with reference to the accompanying drawings. This application is not limited to the description of the following embodiments.

[0017] Example 1

[0018] like Figure 1 and 2 As shown, a tunnel side-mounted culvert 5 blocking observation pipe 1 includes an observation pipe 1, which is fixedly connected to a cover plate 2 of the side-mounted culvert 5. The observation pipe 1 is a transparent observation pipe 1, with one end open and the other end closed. A transparent scale 3 is fixedly installed on the side wall of the observation pipe 1, and a transparent sealing cap 4 is detachably installed at the open end of the observation pipe 1. An insertion port is provided on the cover plate 2, and the closed end of the observation pipe 1 extends into the bottom of the side-mounted culvert 5 through the insertion port. Further, the length of the observation pipe 1 is 60-80 cm and the diameter is 5 cm.

[0019] See attached document Figure 2 and 3 Furthermore, the opening end of the observation tube 1 is 5 cm away from the upper surface of the cover plate 2. Furthermore, the observation tube 1 includes a transparent tube body 11 and a circular base 12 fixedly disposed at one end of the transparent tube body 11, the circular base 12 being fixed to the bottom of the transparent tube body 11 by adhesive bonding. Furthermore, the observation tube 1 is an acrylic round tube, a PC round tube, or a PVC round tube.

[0020] In use: 1. Drill a hole in the top of the cover plate 2, with the hole diameter slightly larger than the diameter of the observation tube 1 opening. 2. Cut the tube according to the depth of the cover plate 2 + trench bottom, leaving about 5cm for easy installation of the sealing cap. 3. Clean the inner tube wall (cut off any residual material), select one end as the bottom, and attach a transparent height gauge to the inner tube wall. Use 502 or other adhesive materials to seal the bottom using the round base 12. 4. Insert the observation tube 1 with the bottom closed. Seal the gap between the drilled hole and the tube wall with foam glue or similar materials for fixation. 5. After installation, seal with the transparent sealing cap 4. 6. When observation is needed, open the sealing cap and adjust the camera of the external endoscope 9 to the desired angle for observation (the rigid wire helps to fix the angle, and the surrounding crystallization and water level can be observed by rotation). 7. If there is no water, the light transmittance is reduced, and you can directly observe whether there is crystallization around the bottom; if there is water, the light transmittance is enhanced, and you can directly record the current water level and the surrounding crystallization. When analyzing, you should determine whether to take action based on comprehensive factors such as water level, crystallization, culvert height, water level difference between observation points before and after, and the history of water seepage damage to the tunnel surface.

[0021] Analysis of the positive effects of the above embodiments:

[0022] Low maintenance costs: It is estimated that the outer wall of observation tube 1 will be contaminated by crystals for more than a year. Subsequent maintenance only requires scraping off the crystals from the outer wall of observation tube 1 and resealing and reinstalling it, with no additional maintenance costs.

[0023] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this application and should not be construed as limiting the specific implementation of this application to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this application, and all such modifications or substitutions should be considered within the scope of protection of this application.
