Description

Technical Field

[0001] This utility model relates to the field of diversion tunnel template technology, specifically a diversion tunnel inlet template. Background Technology

[0002] Inlet formwork for diversion tunnels is a specialized formwork used in hydraulic engineering for the concrete pouring of the inlet section of diversion tunnels. Its main function is to provide forming support for the concrete structure at the inlet of the diversion tunnel, ensuring that the shape, size, and precision of the inlet section meet design requirements, while also guaranteeing stability and safety during the concrete pouring process.

[0003] Currently, the formwork for the inlet of diversion tunnels on the market has an integrated structure. The overall height of the integrated formwork cannot be adjusted, resulting in a limited range of applications. In addition, if the formwork is not well supported during concrete pouring, it may deform, thus affecting the formation of the tunnel. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a diversion tunnel inlet template, which has the advantages of strong practicality and resistance to deformation, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a diversion tunnel inlet template, comprising two first template mechanisms, each of the two first template mechanisms having a second template mechanism snapped onto its upper end face, each of the two second template mechanisms having a third template mechanism snapped onto its upper end face, and a first template snapped onto the upper end face of each of the two third template mechanisms. An adhesive sealing strip is bonded between the two first template mechanisms and the two second template mechanisms. A base is fixedly connected between the two first template mechanisms. Two second connecting plates are fixedly installed on the upper end face of the base. A second support mechanism is fixedly installed on the outer sides of each of the two second connecting plates. A first connecting plate is fixedly installed on the upper end face of the two second connecting plates. A first support mechanism is fixedly installed on the upper end face of the first connecting plate. A side template is fixedly installed on one side of one of the two first template mechanisms.

[0006] As a preferred technical solution of this utility model, the first template mechanism includes a second template, and a first snap-fit ​​hole is provided on the upper end face of the second template.

[0007] As a preferred embodiment of the present invention, the second template mechanism includes a third template, the upper end face of which is provided with a second snap-fit ​​hole, and the lower end face of which is fixedly installed with a first snap-fit ​​block.

[0008] As a preferred technical solution of this utility model, the third template mechanism includes a fourth template, and a second snap-fit ​​block is fixedly installed on the lower end face of the fourth template.

[0009] As a preferred embodiment of the present invention, the first support mechanism includes a hydraulic rod, and a support block is fixedly installed on the upper end face of the hydraulic rod.

[0010] As a preferred embodiment of the present invention, the second support mechanism includes a second hydraulic rod, and a second support block is fixedly installed on one side of the second hydraulic rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The diversion tunnel inlet template is composed of a first template mechanism, a second template mechanism, a third template mechanism, and a No. 1 template. The template mechanisms and templates are interlocked and fixed to form the whole diversion tunnel inlet template. When facing different diversion tunnels, the height of the tunnel template can be changed by interlocking an appropriate number of second template mechanisms with the first and third template mechanisms, so that the template fits the diversion tunnel better and increases the application range of the template.

[0013] 2. The inlet formwork of the diversion tunnel is equipped with a first support mechanism and a second support mechanism installed on the first and second connecting plates. Before pouring concrete, the first and second hydraulic rods are activated to make the first and second support blocks fit against the inner wall of the formwork, thereby increasing the overall compressive strength of the formwork and effectively preventing deformation during concrete pouring, which would affect the quality of tunnel formation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-7 A diversion tunnel inlet template includes two first template mechanisms 1, with a second template mechanism 2 snapped onto the upper surface of each of the two first template mechanisms 1, a third template mechanism 3 snapped onto the upper surface of each of the two second template mechanisms 2, a first template 4 snapped onto the upper surface of each of the two third template mechanisms 3, an adhesive sealing strip 10 bonded between the two first template mechanisms 1 and the two second template mechanisms 2, a base 8 fixedly connected between the two first template mechanisms 1, two second connecting plates 9 fixedly installed on the upper surface of the base 8, a second support mechanism 7 fixedly installed on the outer sides of each of the two second connecting plates 9, a first connecting plate 6 fixedly installed on the upper surface of the two second connecting plates 9, a first support mechanism 5 fixedly installed on the upper surface of the first connecting plate 6, and a side template 11 fixedly installed on one side of one of the two first template mechanisms 1.

[0024] In the above structure, the first template mechanism 1, the second template mechanism 2, the third template mechanism 3, the first template 4, and the side template 11 are interlocked to form the inlet template frame of the diversion tunnel. At the same time, the joint between the first template mechanism 1 and the second template mechanism 2 on the inner wall of the template is sealed and fixed by using an adhesive sealing strip 10. A base 8 is installed between the two first template mechanisms 1 to support the first support mechanism 5 and the second support mechanism 7. The first support mechanism 5 and the second support mechanism 7 are used to increase the compressive strength of the template to prevent the template from deforming during the concrete pouring process, thereby affecting the tunnel forming quality.

[0025] In a preferred embodiment, the first template mechanism 1 includes a second template 101, with a first snap-fit ​​hole 102 on the upper surface of the second template 101; the second template mechanism 2 includes a third template 201, with a second snap-fit ​​hole 202 on the upper surface of the third template 201, and a first snap-fit ​​block 203 fixedly installed on the lower surface of the third template 201; the third template mechanism 3 includes a fourth template 301, with a second snap-fit ​​block 302 fixedly installed on the lower surface of the fourth template 301.

[0026] In the above structure, the tunnel formwork is formed by interlocking the No. 1 snap-fit ​​hole 102 and the No. 1 snap-fit ​​block 203, and the No. 2 snap-fit ​​hole 202 and the No. 2 snap-fit ​​block 302. When dealing with tunnels of different heights, different numbers of second formwork mechanisms 2 can be installed between the first formwork mechanism 1 and the third formwork mechanism 3 to change the height of the tunnel formwork. This makes the tunnel formwork fit the tunnel better, which can increase the application range of the formwork and improve the quality of the concrete poured in the tunnel.

[0027] In a preferred embodiment, the first support mechanism 5 includes a first hydraulic rod 502, and a first support block 501 is fixedly installed on the upper end face of the first hydraulic rod 502; the second support mechanism 7 includes a second hydraulic rod 702, and a second support block 701 is fixedly installed on one side of the second hydraulic rod 702.

[0028] In the above structure, the extension and retraction of hydraulic rod 502 and hydraulic rod 702 cause support block 501 and support block 701 to fit against the inner wall of the template. The support blocks increase the compressive strength of the template, thereby preventing the template from deforming during concrete pouring and affecting the forming quality of the tunnel.

[0029] The working principle is as follows: based on the height of the tunnel, a suitable number of second template mechanisms 2 are snapped and installed between the first template mechanism 1 and the third template mechanism 3 to form the overall frame of the tunnel template. This also allows the template to fit the tunnel better, increasing the usability of the template. After the template is installed and before the concrete is poured, the expansion and contraction of the first hydraulic rod 502 and the second hydraulic rod 702 cause the first support block 501 and the second support block 701 to fit against the inner wall of the template, thereby increasing the compressive strength of the template and preventing the template from deforming during the concrete pouring process, which would affect the quality of the tunnel formation.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
