Description

Technical Field

[0001] This utility model relates to the field of tunnel waterproof membrane laying technology, and in particular to a top surface treatment structure that facilitates the construction of tunnel waterproof membranes. Background Technology

[0002] Tunnel waterproof membranes are materials used in tunnel engineering to prevent the seepage of groundwater, rainwater, and other water sources. They effectively prevent groundwater, rainwater, and other water sources from penetrating into the tunnel interior, protecting the tunnel structure from water erosion, preventing leaks and water accumulation, ensuring the normal use and safe operation of the tunnel, avoiding steel corrosion and concrete corrosion caused by long-term contact with moisture in the tunnel lining structure, extending the service life of the tunnel structure, reducing maintenance costs, and helping to maintain a dry environment inside the tunnel. This reduces problems such as increased air humidity and mold growth caused by dampness, providing good environmental conditions for equipment, facilities, and personnel inside the tunnel, and ensuring that the quality of the waterproof membrane material meets design requirements. Check the specifications, model, and performance indicators of the material, such as the thickness, tensile strength, and elongation at break of the waterproof membrane, ensuring these parameters are within the specified range. Prepare auxiliary materials, such as waterproof membrane adhesive (if needed), sealing materials (such as water-swellable sealing strips for construction joints and expansion joints), gaskets, etc. The sealing material must have good water resistance and adhesion to effectively prevent water leakage from gaps. A comprehensive inspection of the waterproof membrane's installation quality is necessary, including its fixation, welding quality, overlap width, and adhesion to the substrate. Check the surface of the waterproof membrane for defects such as damage or holes.

[0003] In the existing technology, when laying a waterproof membrane in a tunnel, a laying vehicle is needed to lay the waterproof membrane on the top of the tunnel while moving around, and the laid waterproof membrane is fixed to the top of the tunnel during the laying process.

[0004] However, when laying the waterproof membrane on the tunnel roof, if there is a protrusion on the tunnel roof, it is easy to puncture the waterproof membrane, causing leakage. In this case, the section needs to be re-laid, which reduces efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a top surface treatment structure that facilitates the construction of waterproof membranes in tunnels, solving the problem in the prior art where protrusions at the top of the tunnel easily damage the waterproof membrane and hinder construction efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A top surface treatment structure for facilitating the construction of waterproof membranes in tunnels includes a paving vehicle. An L-shaped support plate is fixedly connected to the side of the paving vehicle. A motor is fixedly connected to the surface of the support plate. The output shaft of the motor is driven by a rotating rod. Several extension plates are fixedly connected to the surface of the rotating rod. The surface of the extension plates is provided with a pressing rod through a telescopic mechanism. A shovel is fixedly connected to the surface of the pressing rod. A receiving mechanism is provided on the surface of the support plate.

[0008] Preferably, the telescopic mechanism includes an extension groove formed on the surface of the extension plate, a telescopic plate being slidably connected inside the extension groove, and a pressing rod being fixedly connected to the surface of the telescopic plate.

[0009] Preferably, the telescopic plate and the extension groove are elastically connected by a compression spring. The extension groove has a T-shaped cross-section, the telescopic plate has a T-shaped cross-section, and two clamping plates are fixedly connected to the surface of the extension plate.

[0010] Preferably, the receiving mechanism includes an arc-shaped stabilizing plate fixedly connected to the surface of the bearing plate, and the surface of the stabilizing plate has several anti-stacking grooves.

[0011] Preferably, an anti-tilting rod is fixedly connected to the top of the stabilizing plate, and a rotating sleeve is fixedly connected to the top of the anti-tilting rod, with the rotating rod passing through the inside of the rotating sleeve.

[0012] Preferably, an L-shaped cutter is fixedly connected to one end of the compression bar near the paving vehicle.

[0013] This utility model has the following beneficial effects:

[0014] When laying the waterproof membrane in the tunnel, the motor located in front of the laying vehicle needs to be started. The motor can drive the shovel and extrusion rod to remove and clean the protruding parts on the top of the tunnel, ensuring that no protrusion will puncture the waterproof membrane during the laying process.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5A top surface treatment structure for facilitating the construction of waterproof membranes in tunnels includes a laying vehicle 1, which is the existing equipment for laying waterproof membranes in tunnels. During the laying process, the laying vehicle 1 moves inside the tunnel, and the equipment on the laying vehicle 1 lays the waterproof membrane. An L-shaped support plate 2 is fixedly connected to the side of the laying vehicle 1. When the laying vehicle 1 moves to lay the waterproof membrane, the movement of the laying vehicle 1 drives the support plate 2 to move synchronously. The support plate 2 is fixed in the direction of movement of the laying vehicle 1 and is located at a higher position. A motor 3 is fixedly connected to the surface of the support plate 2. The output shaft of the motor 3 is driven by a rotating rod 4. When the laying vehicle 1 moves, the motor 3 needs to be started. After the motor 3 starts, it drives the rotating rod 4 to rotate. Several extension plates 5 are fixedly connected to the surface of the rotating rod 4. A pressing rod 7 is provided on the surface of the extension plates 5 through a telescopic mechanism 6. A scraper 8 is fixedly connected to the surface of the pressing rod 7. When the rotating rod 4 rotates, it drives... The extension plate 5, the extrusion rod 7, and the scraper 8 rotate together. During this process, the scraper 8 is driven by the extrusion rod 7 to clean the tunnel top, preventing sharp edges from appearing on the tunnel top and protecting the laid waterproof membrane. If the tunnel top is low, the extrusion rod 7 can be lowered through the telescopic mechanism 6 to prevent hard contact that could damage the extension plate 5, the extrusion rod 7, or the scraper 8. This buffering mechanism protects the scraper 8 and allows it to clean the tunnel top normally. The extrusion rod 7 and the scraper 8 are both relatively long, ensuring that no area is missed during cleaning of the tunnel top, thus ensuring the waterproof membrane is properly laid. The surface of the bearing plate 2 is equipped with a receiving mechanism 9. When cleaning the tunnel top with the scraper 8, the stability of the scraper 8 needs to be increased. This is achieved by using the receiving mechanism 9 to increase the stability of the structure on the bearing plate 2, thereby increasing the stability of the scraper 8 and allowing it to easily clean the tunnel top.

[0024] Furthermore, the telescopic mechanism 6 includes an extension groove 601 formed on the surface of the extension plate 5. A telescopic plate 602 is slidably connected inside the extension groove 601. The extrusion rod 7 is fixedly connected to the surface of the telescopic plate 602. The telescopic mechanism 6 is needed to buffer the shovel 8 to prevent the shovel 8 from being damaged by directly hitting the tunnel top. In this case, the tunnel top will squeeze the extrusion rod 7, allowing the telescopic plate 602 below the extrusion rod 7 to enter the interior of the extension groove 601. This protects the extrusion rod 7 and the shovel 8 from easy damage, thus extending the service life of the shovel 8.

[0025] Furthermore, the telescopic plate 602 and the extension groove 601 are elastically connected by a compression spring 603. The extension groove 601 has a T-shaped cross-section, and the telescopic plate 602 also has a T-shaped cross-section. Two clamping plates 604 are fixedly connected to the surface of the extension plate 5. After the telescopic plate 602 enters the extension groove 601, it will compress the compression spring 603. At this time, the compression spring 603 will apply force to the telescopic plate 602, thereby causing the compression rod 7 on the telescopic plate 602 to be pressed against the top of the tunnel. At this time, the compression spring 603 needs to be of a type with low elasticity and easy deformation to ensure that the compression rod 7 is pressed against the top of the tunnel. The friction between the telescopic plate 602 and the tunnel top will not be too great, which would make it difficult to move. When the compression rod 7 is no longer compressed by the tunnel top, the telescopic plate 602 can leave the extension groove 601 again by the elastic force of the compression spring 603. During the process of entering and exiting the extension groove 601, the telescopic plate 602 can be restricted by the clamping plate 604 on the extension plate 5, thereby ensuring the stability of the telescopic plate 602 entering and exiting the extension groove 601 and preventing tilting and detachment. This ensures the stability and safety of the telescopic plate 602 during use and ensures that both the compression rod 7 and the shovel 8 can be used normally.

[0026] Furthermore, the receiving mechanism 9 includes an arc-shaped stabilizing plate 901 fixedly connected to the surface of the bearing plate 2. The surface of the stabilizing plate 901 is provided with several anti-piling grooves 902. When using the shovel 8 to clean the top of the tunnel to prevent sharp parts from puncturing the waterproof membrane, the stabilizing plate 901 can protect the rotating rod 4 and its structure, so that the mechanism on the rotating rod 4 will not easily tilt, thereby ensuring that the cleaning of the top of the tunnel can be carried out continuously.

[0027] Furthermore, an anti-tilt rod 903 is fixedly connected to the top of the stabilizing plate 901, and a rotating sleeve 904 is fixedly connected to the top of the anti-tilt rod 903. The rotating rod 4 passes through the inside of the rotating sleeve 904. When the rotating rod 4 is driven by the motor 3, the rotating rod 4 can be restricted by the anti-tilt rod 903 on the rotating sleeve 904, so that the rotating rod 4 will not easily tilt and be damaged. When in use, the rotating rod 4 is supported on the stabilizing plate 901 by the rotating sleeve 904 and the anti-tilt rod 903, which increases the safety and stability of the rotating rod 4.

[0028] Furthermore, an L-shaped hook 10 is fixedly connected to one end of the extrusion bar 7 near the paving vehicle 1. When the shovel 8 cleans the top of the tunnel, if there are any parts that have not been cleaned, they can be cleaned by the hook 10, which makes the cleaning effect better and makes the laid waterproof membrane safer.

[0029] In summary:

[0030] When laying a waterproof membrane inside the tunnel, the laying vehicle 1 is used to move the membrane onto the tunnel ceiling. First, the motor 3 on the bearing plate 2 is started. After the motor 3 starts, it drives the rotating rod 4 to rotate. The rotation of the rotating rod 4 causes the extension plate 5 to rotate as well. The pressing rod 7 and the scraper 8 on the extension plate 5 also rotate together, allowing the scraper 8 to contact the tunnel ceiling and scrape off the protrusions. Several scrapers 8 can be driven by the motor 3 to rotate and repeatedly clean the tunnel ceiling. This better protects the safety of the waterproof membrane during subsequent laying. When the scraper 8 and pressing rod 7 are against the tunnel ceiling, the telescopic plate 602 can enter the extension groove 601, protecting the integrity of the scraper 8 and pressing rod 7 and ensuring that the scraper 8 and pressing rod 7 can adhere to the tunnel ceiling for cleaning. When the scraper 8 and pressing rod 7 are not compressed by the tunnel ceiling, the telescopic plate 602 can be ejected by the elastic force of the compression spring 603. When the telescopic plate 602 enters and exits the extension slot 601, the clamping plate 604 ensures safety. When the shovel 8 cleans the tunnel top, the stabilizing plate 901 can easily protect the mechanism on the rotating rod 4. The anti-stallization slot 902 allows the scraped debris to leak out and not accumulate inside the stabilizing plate 901. The rotating rod 4 can be easily stabilized by the rotating sleeve 904 and the anti-tilting rod 903, preventing it from easily tilting and being damaged. The shovel 8, in cooperation with the squeezing rod 7, cleans the tunnel top. It can also be used with the hanging knife 10 to check and clean the protrusions again, resulting in a better cleaning effect on the tunnel top. Through the above structure, when it is necessary to lay the waterproof membrane in the tunnel, the tunnel top can be checked and cleaned before laying to prevent the protrusions from damaging the waterproof membrane. In addition, if it cannot be scraped, it will also block the movement of the laying vehicle 1, preventing the waterproof membrane from being laid in the position of the protrusion. This facilitates the safe construction of the waterproof membrane and ensures the safety of the waterproof membrane construction.
