[0017] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.
[0018] Example:
[0019] like Figure 1-Figure 3As shown, this embodiment provides a buried waterstop installation device in a tunnel, including a back plate 1, a lower top plate 2 and an upper pressure plate 3. The back plate 1 is connected to the end formwork to ensure the stability of the back plate 1. The lower top plate 2 and the upper pressure plate 3 are both installed on the side of the back plate 1 away from the end formwork to ensure the stability of the lower top plate 2 and the upper pressure plate 3, and the upper pressure plate 3 is located above the lower top plate 2; a waterstop installation groove is formed between the lower top plate 2 and the back plate 1 to ensure that there is enough space to install the waterstop 4, and then the lower part of the waterstop 4 is passed through the waterstop installation groove; one side of the upper pressure plate 3 is rotatably connected to the back plate 1 to ensure stability, and the other side of the upper pressure plate 3 presses the upper part of the waterstop 4 onto the lower top plate 2, and supports the upper part of the waterstop 4 through the upper part of the lower top plate 2, ensuring the stability of the waterstop 4 and ensuring that the waterstop is installed in the correct position 4. At the same time, combined with the upper pressure plate 3, a better protection effect is formed, which can effectively prevent the waterstop 4 from being damaged.
[0020] The utility model is installed on the end template through the back plate 1 to ensure the overall stability, and then the back plate 1 is cooperated with the lower part of the lower top plate 2 to form a waterstop installation groove, and the lower part of the waterstop 4 can be installed, and the upper part of the waterstop 4 is supported on the upper end of the lower top plate 2 to ensure that the waterstop is installed in the correct position 4, and then it is pressed and formed through the upper pressure plate 3 to form an upper protection, which can effectively prevent the waterstop 4 from being damaged.
[0021] As a preferred implementation scheme in this embodiment, it needs to be further explained that the upper part of the lower top plate 2 is an arc-shaped support portion extending toward the side away from the back plate 1. The arc-shaped support portion can better support the waterstop 4, so that the waterstop 4 maintains the correct installation method. The other side of the upper pressure plate 3 presses the upper part of the waterstop 4 against the arc-shaped support portion of the lower top plate 2, thereby forming a better protective effect.
[0022] As a preferred implementation scheme in this embodiment, it needs to be further explained that the lower end of the lower top plate 2 is a connecting portion connected to the back plate 1 to ensure the stability of the lower top plate 2, and the middle part of the lower top plate 2 between the connecting portion and the arc-shaped support portion is provided with a limiting portion parallel to the back plate 1, and the limiting portion cooperates with the back plate 1 to form the waterstop installation groove to ensure the quick installation of the waterstop 4.
[0023] As a preferred implementation scheme in this embodiment, it needs to be further explained that at least one pressure plate screw 5 is arranged above the upper pressure plate 3, and the lower end of the pressure plate screw 5 is movably connected to the other side of the upper pressure plate 3. An avoidance groove or avoidance hole is provided on the back plate 1 corresponding to the upper part of the pressure plate screw 5, and the upper part of the pressure plate screw 5 is arranged in the avoidance groove or avoidance hole. The avoidance groove or avoidance hole is relatively large and does not affect the rotation and swing of the pressure plate screw 5, and the pressure plate screws 5 on both sides of the avoidance groove or avoidance hole are threadedly connected with limiting nuts 6, and then the relative position of the pressure plate screw 5 and the avoidance groove or avoidance hole can be limited by the two limiting nuts 6, thereby adjusting the swing angle of the other side of the upper pressure plate 3.
[0024] As a preferred implementation scheme in this embodiment, it needs to be further explained that a movable ball 7 is embedded in the upper end of the other side of the upper pressure plate 3, and the lower end of each pressure plate screw 5 is threadedly connected to a movable ball 7, which does not affect the rolling of the movable ball 7. In this way, the angle of the other side of the upper pressure plate 3 can be adjusted by the pressure plate screw 5.
[0025] As a preferred implementation scheme in this embodiment, it needs to be further explained that there are two pressure plate screws 5, and the two pressure plate screws 5 are respectively arranged on both sides above the upper pressure plate 3. By dispersing gravity through the two pressure plate screws 5, the upper pressure plate 3 can be subjected to force more evenly, thereby ensuring its service life.
[0026] As a preferred technical solution in the present invention, the upper and lower parts of the back plate 1 are provided with connection holes 8 for convenient connection with the end template through bolts, thereby making the back plate 1 more stably connected to the end template.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
