Description

Technical Field

[0001] The utility model relates to the technical field of building auxiliary equipment, in particular to a prefabricated culvert back-sticking waterstop. Background Art

[0002] Culverts, a crucial component of engineering construction, are prefabricated concrete structures commonly used in roads, railways, tunnels, and other projects to allow water to flow underneath while ensuring the safety of the building foundation. Culverts primarily consist of a tunnel body, foundation, end and wing walls, and play the vital role of rapidly draining surface water and ensuring the safety of the roadbed. As drainage channels, prefabricated culverts require crucial waterproofing. During use, they may be affected by various external forces, such as foundation settlement and temperature fluctuations, which can cause deformation. The waterproofing treatment of the joints between the concrete pipes used in culverts is directly related to the stability and safety of the entire project.

[0003] Due to its excellent waterproofing properties, back-attached waterstops are the preferred material for waterproofing joints between concrete pipes used in culverts. Back-attached waterstops are primarily made from natural rubber, EPDM, or various synthetic rubbers, with the addition of various additives and fillers, and are manufactured through processes such as plastication, mixing, and compression molding. They utilize rubber's high elasticity and compression properties to elastically deform under various loads, effectively tightening and sealing the culvert, preventing leakage and seepage. Back-attached waterstops exhibit excellent deformation adaptability, maintaining a tight seal even when the culvert deforms, preventing water infiltration.

[0004] However, the current structure of the back-attached waterstop is not suitable for use in prefabricated culverts. The ridges of the waterstop hinder on-site installation, preventing a close fit and achieving waterproofing. Specifically, due to the current construction process, the existing waterstop is left exposed, failing to meet waterproofing requirements. The current back-attached waterstop structure is connected to the mounting surface of the concrete pipe used in the culvert. The presence of the ridges leaves the waterproof surface of the waterstop exposed, thus compromising its waterproofing effectiveness. Utility Model Content

[0026] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] As described in the background art, the current structure in the prior art cannot meet the working conditions of applying the back-stick waterstop to the prefabricated culvert. The edges of the waterstop affect the on-site installation and cannot be closely attached to the surface to achieve waterproofing.

[0028] Based on this, the utility model provides a prefabricated culvert back-sticking waterstop, which adopts a settlement deformation adaptive structure and a waterproof stripe structure. The waterproof stripe structure is easier to compress and deform than the rubber flat plate structure. The better the deformation effect, the stronger the waterproof performance. It can also make the waterstop body fit completely with the prefabricated culvert, improving the waterproof performance while improving the disadvantages of the existing waterstop that cannot meet the current waterstop construction process, resulting in the waterstop edges being suspended and prone to leakage.

[0029] The following is combined with specific Figure 1-3 The structure of the prefabricated culvert back-sticking waterstop of the utility model is described in detail.

[0030] like Figure 1 As shown, the prefabricated culvert back-sticking waterstop includes a waterstop body 1, which is a rubber product with a certain width and thickness synthesized using natural rubber or EPDM rubber or various synthetic rubbers as main raw materials.

[0031] In this embodiment, a settlement deformation adaptive structure 11 is provided on one side surface of the waterstop body 1. The settlement deformation adaptive structure 11 is located in the middle position of the waterstop body 1. The bottom of the settlement deformation adaptive structure 11 is set to be U-shaped. At least one side of the settlement deformation adaptive structure 11 is provided with a settlement waterproof stripe structure 111. The settlement deformation adaptive structure 11 of this embodiment has a settlement waterproof stripe structure 111 on both sides. The settlement waterproof stripe structure 111 is preferably a bar tooth, more preferably a trapezoidal bar tooth. The settlement waterproof stripe structure 111 and the settlement deformation adaptive structure 11 are integrally formed.

[0032] A U-shaped settlement deformation adaptive structure 11 is used to adapt to the settlement deformation between culverts. When the U-shaped settlement deformation adaptive structure 11 is installed within the width of the culvert joint, the waterproof stripes are compressed and deformed, thereby forming a waterproof area at the anchoring position.

[0033] It should be noted that the subsidence waterproof stripe structure 111 is not limited to trapezoidal strip teeth, but can also be a tooth structure of other shapes. As long as the close anchoring effect can be achieved, the present invention does not limit the shape of the teeth of the subsidence waterproof stripe structure 111.

[0034] The settlement waterproof stripe structure 111 of this embodiment adopts an arc-shaped waterproof stripe structure. When the U-shaped structure is installed in the joint of the culvert, the waterproof stripe is compressed and deformed, thereby forming a waterproof area at the anchoring position. Compared with the trapezoidal structure, the arc-shaped structure makes it easier to install the U-shaped structure downward. The waterproof stripe has small resistance and is less likely to deform in the non-compression direction.

[0035] In addition, see Figure 1 As shown, a waterproof stripe structure is also provided on one side surface of the waterstop body 1. The waterproof stripe structure and the settlement deformation adaptive structure 11 are located on the same side of the waterstop body 1. The waterproof stripe structure is located on both sides of the settlement deformation adaptive structure 11 and extends to the end of the waterstop body 1. The settlement deformation adaptive structure 11 and the waterproof stripe structure are both integrally formed with the waterstop body 1.

[0036] Specifically, such as Figure 1 As shown, the waterproof stripe structure includes an anchoring portion waterproof stripe structure 12 and an arc-shaped waterproof reinforcement portion waterproof stripe structure 13. The arc-shaped waterproof reinforcement portion waterproof stripe structure 13 is located on both sides of the settlement deformation adaptive structure 11. The waterproof stripe structure 13 is arranged in a circular arc convex shape. The anchoring portion waterproof stripe structure 12 and the arc-shaped waterproof reinforcement portion waterproof stripe structure 13 are continuous. The anchoring portion waterproof stripe structure 12 is arranged near the end of the waterstop body 1.

[0037] In this embodiment, both the waterproof stripe structure 12 at the anchoring portion and the waterproof stripe structure 13 at the arc-shaped waterproof reinforcement portion are preferably strip-shaped teeth, more preferably trapezoidal strip-shaped teeth.

[0038] It should be noted that the waterproof stripe structure 12 at the anchoring part and the waterproof stripe structure 13 at the arc-shaped waterproof reinforcement part are not limited to trapezoidal strip teeth, but can also be tooth structures of other shapes. As long as the effect of close anchoring can be achieved, the utility model does not limit the shape of the teeth of the waterproof stripe structure 12 at the anchoring part and the waterproof stripe structure 13 at the arc-shaped waterproof reinforcement part.

[0039] The waterproof stripe structure 12 of the anchoring part of this embodiment adopts a trapezoidal waterproof stripe structure. When the anchoring assembly is firmly anchored, the waterproof stripe is compressed and deformed, thereby forming a waterproof area of ​​the anchoring part.

[0040] The curved waterproof reinforcement stripe structure 13 of this embodiment compresses and deforms the waterproof stripe structure when soil or concrete is filled onto the outside of the culvert. This creates a waterproof area within the curved waterproof reinforcement. The arc-shaped raised arrangement of the waterproof stripe structure 13 generates pressure from above, further compressing and deforming the waterproof stripe structure, thereby enhancing the waterproofing effect.

[0041] In order to form an extrusion on the waterstop body 1, an extrusion block 3 is provided on the opposite side of the waterproof stripe structure 12 at the anchoring part. The extrusion block 3 is annular, and the expansion bolt 2 passes through the extrusion block 3 and the waterstop body 1 at the same time. Since the extrusion block 3 fits tightly with the waterstop body 1 and receives the tightening force of the expansion bolt 2 at the same time, the waterstop body 1 can be extruded.

[0042] And continue to see Figure 1 As shown, in this embodiment, a V-shaped notch structure 112 is provided at the closed end of the U-shaped settlement deformation adaptive structure 11. The V-shaped notch structure 112 has a connection layer less than 5 mm, preferably 2 mm.

[0043] The V-shaped notch structure 112 plays a shaping role, isolating the filling material at the opening of the U-shaped settlement deformation adaptive structure 11 from entering the U-shaped cavity. When the culvert settles and deforms, the 2mm connecting layer tears to form a U-shaped water guide groove, which diverts the water outside the waterstop to the bottom of the culvert.

[0044] like Figure 2 and Figure 3 The figure shows the structure of the prefabricated culvert back-stick waterstop before and after settlement. When settlement deformation occurs, the connecting layer of the V-shaped notch structure 112 is broken and torn, and the U-shaped settlement deformation adaptive structure 11 forms a water guide channel to divert the water outside the waterstop to the bottom of the culvert. At the same time, the U-shaped settlement deformation adaptive structure 11 adapts to the settlement between culverts, avoiding the disadvantage of the waterstop being elongated and thinned due to settlement, which reduces the waterproof effect.

[0045] As a more preferred embodiment, Figure 1 As shown, in this embodiment, both ends of the waterstop body 1 are provided with anti-slip structures 14, and the anti-slip structures 14 are preferably trapezoidal protrusion structures.

[0046] The trapezoidal raised structure reduces the risk of the waterstop slipping off from the anchoring assembly and strengthens the anchoring ability of the waterstop.

[0047] like Figure 1-3As shown, the prefabricated culvert back-attached waterstop is fixed to both sides of the culvert by expansion bolts 2, and the trapezoidal anti-slip structure 14 is provided at both ends of the waterstop, which not only increases the anchoring capacity of the anchor assembly, but also provides positioning for the waterstop installation anchor assembly. When the waterstop is installed in place, the waterproof stripes of the waterstop take effect. When the culvert settles, the 2mm V-shaped notch structure 112 at the opening of the U-shaped settlement deformation adaptive structure 11 tears, and the U-shaped settlement deformation adaptive structure 11 takes effect. The width and thickness of the waterstop before and after settlement will not be deformed, so the waterproof effect will not be reduced.
