[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0024] The embodiments of this application provide a protection mechanism for a waterstop at the deformation joint of a box culvert, which solves the problem in the related art that during the construction of a box culvert project, the waterstop is vulnerable to external impact without external protection, resulting in damage to the waterstop.

[0025] See Figure 1 and Figure 2 As shown in and, the embodiments of this application provide a protection mechanism for a waterstop at the deformation joint of a box culvert, including a box culvert end formwork. The box culvert end formwork includes an outer formwork 21 and an inner formwork 22 that are arranged at intervals. A protection plate 4 for protecting the waterstop 3 is connected to the outer formwork 21 and the inner formwork 22.

[0026] In actual use, the box culvert end formwork is the basic structure of the protection mechanism and is composed of the outer formwork 21 and the inner formwork 22 that are arranged at intervals. These two parts of formwork cooperate closely to jointly define the two side boundaries of the deformation joint of the box culvert. The outer formwork 21 and the inner formwork 22 not only provide the necessary support for the pouring of the box culvert but also provide a basic platform for the subsequent protection of the waterstop 3. The protection plate 4 is connected to the outer formwork 21 and the inner formwork 22 and is used to cover and protect the waterstop 3. The protection mechanism of this application can wrap and protect the waterstop 3, avoiding the waterstop 3 from being impacted by external forces, thereby preventing the waterstop 3 from being damaged and affecting subsequent construction.

[0027] As Figure 1 shown, it is a schematic diagram of the box culvert body 1 with a waterstop 3 provided therein.

[0028] In some alternative embodiments, it further includes a fixing component. The fixing component is used to connect and fix the outer formwork 21 and the inner formwork 22. The fixing component includes a fixing frame 5 connected to the outer formwork 21 and the inner formwork 22.

[0029] In some alternative embodiments, the fixing component further includes a fixing rod 6 anchored to the wall or the ground, and the fixing frame 5 is connected to the fixing rod 6.

[0030] In the protection mechanism of the waterstop 3 at the deformation joint of the box culvert, the fixing component ensures the firm connection between the outer ring formwork 21 and the inner ring formwork 22, thus guaranteeing the stability and reliability of the entire protection mechanism. The fixing component enables these two formworks to form a stable whole at the deformation joint of the box culvert, providing a solid foundation for the subsequent protection of the waterstop 3. The fixing frame 5 is the core component of the fixing component. It is connected to the outer ring formwork 21 and the inner ring formwork 22, playing a role in strengthening and stabilizing the formwork structure.

[0031] To cope with box culvert deformation joints of different sizes, the fixing frame 5 can also be designed with an adjustable length structure. In this way, during the installation process, the length of the fixing frame 5 can be adjusted according to actual needs to ensure the firm connection of the formwork.

[0032] The fixing component firmly connects the outer ring formwork 21 and the inner ring formwork 22 together, forming an integral structure that can resist external force impacts and deformations. This provides a solid foundation for the subsequent installation and protection of the waterstop 3, ensuring the effectiveness and reliability of the waterstop 3 at the deformation joint of the box culvert. At the same time, the detachable design of the fixing component also facilitates the disassembly and reinstallation of the formwork during the construction and maintenance of the box culvert.

[0033] As Figure 2 shown, the function of the fixing rod 6 is to provide additional support and fixing points for the outer ring formwork 21, the inner ring formwork 22, and the fixing frame 5 between them. By anchoring to the walls or ground around the box culvert, the fixing rod 6 can effectively disperse and bear various forces and moments from the formwork, the waterstop 3, and the external environment, thus ensuring the stability and safety of the entire protection mechanism during long-term use. The connection method between the fixing frame 5 and the fixing rod 6 can adopt welding, bolt connection, snap connection, etc. The specific choice of which connection method depends on factors such as design requirements, construction conditions, and cost considerations.

[0034] As Figure 2 shown, in some alternative embodiments, both the outer ring formwork 21 and the inner ring formwork 22 are steel formworks. Both the outer ring formwork 21 and the inner ring formwork 22 adopt steel formworks. Steel formworks have the advantages of high strength, large stiffness, good corrosion resistance, etc., and can withstand various forces and moments during the pouring process of the box culvert, while ensuring the stability and safety of the formwork during long-term use.

[0035] In some alternative embodiments, the protection plate 4 is a steel plate. The protection plate 4 is made of a steel plate. The steel plate has good strength and corrosion resistance, and can effectively resist external impacts and corrosion, ensuring the integrity and functionality of the waterstop 3. In some alternative embodiments, the outer ring formwork 21 is welded and fixed to the protection plate 4, and the inner ring formwork 22 is welded and fixed to the protection plate 4.

[0036] The connection between the protection plate 4 and the outer ring template 21 and the inner ring template 22 is fixed by welding. Welding connection has the advantages of high connection strength and good sealing performance, which can ensure the close fit and stable connection between the protection plate 4 and the template. During the welding process, the weld quality should be ensured to meet the relevant standards to avoid defects such as cracks and pores.

[0037] In some alternative embodiments, such as Figure 2 shown, two adjacent protection plates 4 are rotatably connected, and a clamping space for fixing the water stop 3 is formed between the two adjacent protection plates 4.

[0038] In some alternative embodiments, a hinge 7 is connected between two adjacent protection plates 4.

[0039] The structure between two adjacent protection plates 4 is designed to be openable and closable through rotational connection. This design facilitates the clamping and protection of the water stop 3. Specifically, a hinge 7 or other similar rotational devices can be connected between the adjacent protection plates 4 to ensure that the protection plate 4 can be smoothly opened and closed. When it is necessary to install or inspect the water stop 3, the protection plate 4 can be opened to expose the position where the water stop 3 is located; while when no operation is required, the protection plate 4 can be closed to protect the water stop 3 from the external environment.

[0040] In addition, a clamping space for fixing the water stop 3 is formed between the adjacent protection plates 4. This clamping space ensures that the water stop 3 will not shift or fall off under external forces through the close fit of the protection plates 4 and possible fastening devices.

[0041] In some alternative embodiments, the fixing frame 5 is detachably connected to the outer ring template 21 and the inner ring template 22. Threaded holes are provided on the outer ring template 21 and the inner ring template 22, and threaded structures matching the threaded holes are provided at the ends of the fixing frame 5. To achieve detachable connection, threaded holes can be provided on the outer ring template 21 and the inner ring template 22, and threaded structures matching these threaded holes are provided at the ends of the fixing frame 5. The fixing frame 5 can be tightly connected to the template by rotating it. In addition, other detachable connection methods can also be adopted, such as bolt connection, snap connection and other conventional connection methods. The specific selection depends on factors such as design requirements, construction conditions and cost considerations.
