Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, specifically to a waterproofing plate fixing fixture for a tunnel circumferential blind pipe. Background Technology

[0002] Tunnel waterproofing membranes are mainly used in subways, basements, and tunnel lining for seepage prevention. Installation requires foundation treatment and surface cleaning, ensuring the substrate is flat and the soil is firm. Since circumferential blind pipes in tunnels typically protrude from the wall surface, the waterproofing membrane at these locations needs to be individually secured.

[0003] The existing equipment has the following disadvantages: When the existing device attaches the waterproof membrane at the circumferential blind pipe, it is generally fixed manually. However, manual fixing will result in gaps at the connection between the waterproof membrane and the circumferential blind pipe, and the waterproof membrane cannot be completely attached to the circumferential blind pipe, which will affect the waterproof effect of the waterproof membrane at the circumferential blind pipe.

[0004] Therefore, this application proposes a waterproofing membrane fixing fixture for tunnel circumferential blind pipes to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a waterproofing membrane fixing fixture for a tunnel circumferential blind pipe, so as to solve the problem that manual fixing will result in gaps at the connection between the waterproofing membrane and the circumferential blind pipe, and the waterproofing membrane cannot be completely fitted to the circumferential blind pipe, thus affecting the waterproofing effect of the waterproofing membrane at the circumferential blind pipe.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waterproofing membrane fixing fixture for a circumferential blind pipe in a tunnel, comprising a waterproofing membrane body disposed on the circumferential blind pipe and a plastic-formed plate disposed on the waterproofing membrane body in an Ω-shape, and further comprising:

[0007] A heating unit is disposed on the shaping plate and is used to heat the shaping plate;

[0008] A sliding unit is symmetrically arranged on the heating unit to reduce the friction between the heating unit and the waterproof membrane body.

[0009] The heating unit includes a heating box fixedly mounted on the molding plate, a heating device disposed inside the heating box for heating the molding plate, and a clamping component disposed on the heating box for reinforcing the waterproof plate body and the circumferential blind pipe. The clamping component is connected to the sliding unit.

[0010] The heating device includes a heating wire disposed inside the heating box, a side plate disposed at an angle inside the heating box, and an electric fan disposed on the side plate for blowing hot air toward one side of the waterproof board body. The heating wire is located between the electric fan and the plastic plate.

[0011] The pressing component includes a fixed frame symmetrically arranged on the heating box, a connector arranged on the fixed frame, and a pressing plate arranged on the connector for pressing the waterproof membrane body. The connector is connected to the sliding unit.

[0012] The connecting component includes a pressing rod passing through the fixed frame, a top plate disposed on the upper end of the pressing rod, a fixed rod fixedly disposed on one side of the top plate, a connecting rod sleeved on the fixed rod, and a transmission rod disposed on the sliding unit. The bottom end of the connecting rod is connected to the transmission rod through a connecting block. An elastic element is sleeved on the pressing rod between the top plate and the fixed frame. The lower end of the pressing rod is fixedly disposed on the pressing plate.

[0013] The sliding unit includes a fixed plate disposed at the lower end of the heating box, a sliding frame fixed at the lower end of the fixed plate, a rotating shaft spaced apart inside the sliding frame, and a roller sleeved on the rotating shaft, with the lower end of the roller protruding from the sliding frame.

[0014] The sliding frame has an arc-shaped protective plate on one side for protecting the waterproof membrane body.

[0015] One of the rotating shafts extends out of the sliding frame from the side of the shaping plate. A wheel is provided at a position outside the sliding frame on the rotating shaft. A mounting block is fixedly provided on the wheel. The lower end of the transmission rod is sleeved on the mounting block.

[0016] The heating box is equipped with a handle at the top.

[0017] The molding plate has heat dissipation holes evenly distributed throughout.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention fixes an Ω-shaped molding plate onto a heating unit, then heats the heating unit to a specified temperature. The heating unit is then placed on the waterproof membrane body, ensuring the molding plate matches the shape of the circumferential blind tube. The molding plate is then secured to the circumferential blind tube and left to stand for 30 seconds, allowing the heating unit to heat the waterproof membrane body, ensuring it adheres tightly to the circumferential blind tube. Once the waterproof membrane body and circumferential blind tube are firmly in place, a sliding unit moves the heating unit to the next cycle. The laying effect of the waterproof membrane body is then checked; if the effect is poor, the heating unit is used for supplementary treatment. During the installation process, an appropriate width of waterproof membrane body should be reserved at the circumferential blind pipe to ensure effective installation of the waterproof membrane body. When using this device to bond the circumferential blind pipe and the waterproof membrane body, there should be a certain overlap length between the front and rear loops to ensure the installation effect of the waterproof membrane body. Compared with conventional manual installation, this device simplifies the operation, saves labor costs and construction time, effectively reduces the possibility of waterproof membrane damage, and enables a tight fit between the waterproof membrane body and the circumferential blind pipe, improving the quality of waterproof membrane installation and even enhancing the quality of secondary lining pouring.

[0020] 2. In this invention, the wheel contacts the waterproof membrane body. When the heating box moves on the waterproof membrane body, the wheel drives the mounting block to rotate, which in turn drives the transmission rod to move up and down. This allows the wheel to provide a squeezing force on the pressure plate during rotation. The pressure plate squeezes the waterproof membrane body once for every revolution of the wheel, thus improving the stability of the waterproof membrane body and the circumferential blind tube.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-13 This invention provides a technical solution: a waterproofing membrane fixing fixture for a tunnel circumferential blind pipe, comprising a waterproofing membrane body 2 disposed on the circumferential blind pipe 1 and a plasticized plate 4 disposed on the waterproofing membrane body 2 in an Ω-shape, the plasticized plate 4 being made of polyetheretherketone (PEEK) material capable of withstanding high temperatures up to 300℃, with a smooth thin metal plate inlaid on its inner surface, and further comprising:

[0037] Heating unit 3 is installed on the shaping plate 4 and is used to heat the shaping plate 4;

[0038] The sliding unit 5 is symmetrically arranged on the heating unit 3 to reduce the friction between the heating unit 3 and the waterproof plate body 2.

[0039] It should be noted that during operation, the Ω-shaped molding plate 4 is fixed onto the heating unit 3. The heating unit 3 is then heated to the specified temperature and placed on the waterproof membrane body 2. The molding plate 4 matches the shape of the circumferential blind tube 1. The molding plate 4 is then secured onto the circumferential blind tube 1 and left to stand for 30 seconds. This allows the heating unit 3 to heat the waterproof membrane body 2, ensuring it adheres tightly to the circumferential blind tube 1. Once the waterproof membrane body 2 and circumferential blind tube 1 are firmly in place, the heating unit 3 is moved to the next cycle via the sliding unit 5. The laying effect of the waterproof membrane body 2 is then checked. If the effect is poor, adjustments are made. Heating unit 3 performs the patching operation. A suitable width of waterproof membrane body 2 should be reserved at the circumferential blind pipe 1 to ensure the effective laying of waterproof membrane body 2. When using this device to bond the circumferential blind pipe 1 and the waterproof membrane body 2, there should be a certain overlap length between the front and rear loops to ensure the laying effect of the waterproof membrane body 2. By setting this device, compared with conventional manual laying construction, the operation is simple, saves labor costs and construction time, effectively reduces the possibility of waterproof membrane damage, and can achieve a tight bond between the waterproof membrane body 2 and the circumferential blind pipe 1, improving the laying quality of the waterproof membrane body 2, and even improving the pouring quality of secondary lining.

[0040] In one embodiment, the heating unit 3 includes a heating box 31 fixedly mounted on the molding plate 4, a heating device disposed inside the heating box 31 for heating the molding plate 4, and a clamping component 37 disposed on the heating box 31 for reinforcing the waterproof plate body 2 and the circumferential blind pipe 1. The clamping component 37 is connected to the sliding unit 5.

[0041] With this design, the heating device is turned on to heat the inside of the heating box 31, and then the heat is transferred to the molding plate 4, which heats up the molding plate 4 and softens the waterproof board body 2, so that the waterproof board body 2 and the circumferential blind tube 1 fit tightly together. The sliding unit 5 can drive the heating box 31 to slide on the waterproof board body 2, reducing the frictional resistance of the heating device during the sliding process.

[0042] In one embodiment, the heating device includes a heating wire 33 disposed inside the heating box 31, a side plate 34 disposed at an angle inside the heating box 31, and an electric fan 35 disposed on the side plate 34 for blowing hot air toward one side of the waterproof board body 2. The heating wire 33 is located between the electric fan 35 and the shaping plate 4.

[0043] With this design, the heating wire 33 generates heat, which is then blown onto the molding plate 4 by the fan 35, causing the molding plate 4 to heat up. The molding plate 4 then comes into contact with the waterproof membrane body 2, heating and softening the waterproof membrane body 2. The fan 35 ensures that the heating wire 33 heats the molding plate 4 evenly, which in turn ensures that the molding plate 4 heats the waterproof membrane body 2 evenly, further improving the bonding efficiency between the waterproof membrane body 2 and the circumferential blind tube 1.

[0044] In one embodiment, the pressing component 37 includes a fixing frame 371 symmetrically arranged on the heating box 31, a connector 372 arranged on the fixing frame 371, and a pressing plate 373 arranged on the connector 372 for pressing the waterproof membrane body 2. The connector 372 is connected to the sliding unit 5.

[0045] With this design, when the sliding unit 5 slides on the waterproof membrane body 2, it drives the connector 372 to move, so that the connector 372 drives the pressing plate 373 to press towards the side closer to the waterproof membrane body 2, thereby pressing and fixing the heated and softened waterproof membrane body 2 and the circumferential blind tube 1, and improving the stability of the fixation between the waterproof membrane body 2 and the circumferential blind tube 1.

[0046] In one embodiment, the connector 372 includes a pressing rod 3721 passing through the fixed frame 371, a top plate 3722 disposed on the upper end of the pressing rod 3721, a fixed rod 3723 fixedly disposed on one side of the top plate 3722, a connecting rod 3724 sleeved on the fixed rod 3723, and a transmission rod 3726 disposed on the sliding unit 5. The bottom end of the connecting rod 3724 is connected to the transmission rod 3726 through a connecting block 3725. An elastic element 3727 is sleeved between the top plate 3722 and the fixed frame 371. The lower end of the pressing rod 3721 is fixedly disposed on the pressing plate 373. The elastic element 3727 is made of a spring or an elastic pad.

[0047] With this design, during the movement of the sliding unit 5, the transmission rod 3726 moves up and down, causing the connecting rod 3724 to move the top plate 3722 up and down. This, in turn, causes the pressing rod 3721 to move the pressing plate 373 up and down on the waterproof membrane body 2. The pressing plate 373 presses and fixes the waterproof membrane body 2. When the top plate 3722 moves down, it presses the elastic element 3727. When the transmission rod 3726 moves the connecting rod 3724 up, the elastic element 3727 moves the pressing plate 373 up and resets through the pressing rod 3721. This allows the sliding unit 5 to press the pressing plate 373 against the waterproof membrane body 2 and the circumferential blind tube 1 during the movement of the sliding unit 5, without the need for external force, further improving the stability of the waterproof membrane body 2 and the circumferential blind tube 1.

[0048] In one embodiment, the sliding unit 5 includes a fixed plate 32 disposed at the lower end of the heating box 31, a sliding frame 51 fixed at the lower end of the fixed plate 32, a rotating shaft 53 spaced apart inside the sliding frame 51, and a roller 54 sleeved on the rotating shaft 53, with the lower end of the roller 54 protruding from the sliding frame 51.

[0049] With this design, the roller 54 contacts the waterproof plate body 2, and when the heating box 31 is pushed forward, the roller 54 rolls on the waterproof plate body 2, which can reduce the friction between the sliding frame 51 and the waterproof plate body 2 when the sliding frame 51 moves on the waterproof plate body 2, thereby facilitating the adjustment of the movement position of the entire molding device.

[0050] In one embodiment, a protective plate 52 with an arc shape is provided on one side of the sliding frame 51 for protecting the waterproof plate body 2.

[0051] With this design, the protective plate 52 at the front end of the sliding frame 51 is arc-shaped, which facilitates the movement of the device on the circumferential blind tube 1, while preventing the sliding frame 51 from puncturing the waterproof plate body 2.

[0052] In one embodiment, a rotating shaft 53 extends through a sliding frame 51 on one side of the molding plate 4. A wheel 55 is provided at a position outside the sliding frame 51 where the rotating shaft 53 is located. A mounting block 551 is fixedly provided on the wheel 55. The lower end of the transmission rod 3726 is sleeved on the mounting block 551.

[0053] With this design, the wheel 55 contacts the waterproof membrane body 2. When the heating box 31 is pushed to move on the waterproof membrane body 2, the wheel 55 drives the mounting block 551 to rotate, which in turn drives the transmission rod 3726 to move up and down. This allows the wheel 55 to provide a squeezing force to the pressure plate 373 during rotation. The pressure plate 373 squeezes the waterproof membrane body 2 once for every revolution of the wheel 55, improving the stability of the waterproof membrane body 2 and the circumferential blind tube 1.

[0054] In one embodiment, a handle 36 is provided at the upper end of the heating box 31.

[0055] This design allows workers to use the handle 36 to move the heating box 31 on the waterproof membrane body 2, making it convenient for workers to operate and improving the construction efficiency and laying quality of the waterproof membrane body 2. It has the advantages of simple operation, safety and reliability, and saving manpower.

[0056] In one embodiment, heat dissipation holes 41 are uniformly formed on the shaped plate 4.

[0057] This design allows hot air to be blown directly from the heat dissipation hole 41 onto the waterproof plate body 2, improving the softening efficiency of the heating wire 33 on the waterproof plate body 2.
