DETAILED DESCRIPTION

[0025] In order to make the purpose and advantages of the utility model more clear and apparent, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the specific protection scope requested by the utility model.

[0026] As Figures 1-7 shown, a mounting structure of waterproof plate for tunnel, including main body disc 1, the bottom of main body disc 1 is provided with sealing device 2, sealing device 2 includes threaded rod 21, the top of threaded rod 21 is fixedly connected on the bottom of main body disc 1, the bottom of threaded rod 21 is fixedly connected with stabilizing block 22, the side of stabilizing block 22 is fixedly connected with slide bar 23, the side of slide bar 23 away from stabilizing block 22 is fixedly connected with sealing frame 24, the circumferential surface of slide bar 23 is slidably connected with horizontal slider 25, the side of horizontal slider 25 is articulated with upper articulated rod 26, the screw surface of threaded rod 21 is threadedly connected with threaded block 27, the end of upper articulated rod 26 away from horizontal slider 25 is articulated on the side of threaded block 27, the top of threaded block 27 is fixedly connected with sealing disc 28, the circumferential surface of slide bar 23 is fixedly connected with limiting ring 29, the side of stabilizing block 22 is fixedly connected with limiting soft pad 210.

[0027] Main body disc 1 is located on the movement track of sealing disc 28, and the outer diameter of threaded rod 21 is equal to the inner diameter of sealing disc 28.

[0028] The outer diameter of main body disc 1 is equal to the outer diameter of sealing disc 28, and limiting soft pad 210 is located on the movement track of horizontal slider 25.

[0029] According to the above structure, rotating the main body disc 1, the main body disc 1 rotates to drive the threaded rod 21 to rotate, the threaded rod 21 rotates to drive the threaded block 27 to move upwards, the threaded block 27 moves upwards to make the horizontal sliding block 25 slide along the sliding rod 23 to the stable block 22 under the action of the upper hinge rod 26, and then the horizontal sliding block 25 slides to the position of the limiting soft pad 210 and contacts with it. Because the limiting soft pad 210 is made of high toughness material, the adhesion and fastening of the horizontal sliding block 25 can be enhanced, so that the durability of the sealing device 2 as a whole is significantly improved. At the same time, the upward movement of the threaded block 27 drives the sealing disc 28 to slide upwards, so that the sealing disc 28 is in close contact with the main body disc 1. Because the outer diameter of the main body disc 1 is equal to the outer diameter of the sealing disc 28, and the inner diameter of the threaded rod 21 is equal to the inner diameter of the sealing disc 28, the moisture outside the tunnel wall can be effectively isolated from the main body disc 1, ensuring dry connection between the main body disc 1 and the waterproof plate, avoiding leakage at the connection between the waterproof plate and the nail body in the later period, and prolonging the service life of the waterproof plate.

[0030] As shown in Figures 1-7 , the bottom of the stable block 22 is provided with a fixing device 3, the fixing device 3 includes an extension cone rod 31, the top of the extension cone rod 31 is fixedly connected to the bottom of the stable block 22, the side of the extension cone rod 31 is hingedly connected with a lower hinge rod 32, the end of the lower hinge rod 32 away from the extension cone rod 31 is hingedly connected to the side of the horizontal sliding block 25, the bottom of the sealing frame 24 is fixedly connected with a fixed frame 33, the bottom of the fixed frame 33 is fixedly connected with a bottom cone 34, a sliding ring 36 is fixedly connected through the circumferential surface of the fixed frame 33, a vertical rod 35 is fixedly connected to the circumferential surface of the sliding ring 36, the bottom of the vertical rod 35 is fixedly connected to the top of the bottom cone 34, a reinforcing nail 37 is slidingly connected to the inner wall of the sliding ring 36, the side of the reinforcing nail 37 is fixedly connected with a cone block 38, the side of the extension cone rod 31 is fixedly connected with a limiting clamping tooth 39, and the top of the bottom cone 34 is fixedly connected with a cone rod pad 310.

[0031] The side of the cone block 38 is provided with a tapered surface, and the bottom of the extension cone rod 31 is provided with a tapered surface.

[0032] The tapered surface of the cone block 38 is located on the movement track of the extension cone rod 31, and the cone rod pad 310 is located on the movement track of the extension cone rod 31.

[0033] According to the above structure, the horizontal slider 25 slides along the slide rod 23 under the action of the lower hinged rod 32, so that the telescopic taper rod 31 slides and extends downward, the taper surface of the telescopic taper rod 31 first contacts the inclined taper surface of the taper block 38, so that the taper block 38 is pushed away from the telescopic taper rod 31, the movement of the taper block 38 away from the telescopic taper rod 31 drives the reinforcing nail 37 to slide along the inner wall of the slide ring 36, so that the reinforcing nail 37 is embedded into the inner wall of the nail hole; the telescopic taper rod 31 slides and extends, driving the limiting tooth 39 to move downward, when the limiting tooth 39 moves past the taper block 38, the top surface of the limiting tooth 39 contacts the bottom surface of the taper block 38, the telescopic taper rod 31 continues to slide and extend downward until it contacts the taper rod pad 310, because the taper rod pad 310 is made of high-tough elastic material, so after the telescopic taper rod 31 contacts the taper rod pad 310, the taper rod pad 310 exerts a reverse pushing force on the telescopic taper rod 31, so that the limiting tooth 39 tightly engages with the taper block 38, thereby limiting the position of the telescopic taper rod 31, ensuring that the position of the reinforcing nail 37 will not retreat in the later stage, and the previous fixing method is a drilling-in fixing method, which can cause gaps in the tunnel body, so the drilling-in fixing method is changed to an insertion fixing method, which can ensure the durability and fixing ability of the nail body, and will not damage the stability of the tunnel body.

[0034] The above only describes preferred embodiments of the present application, and it should be pointed out that for ordinary skilled persons in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered within the scope of protection of the present application.
