Description

Technical Field

[0001] The utility model relates to the technical field of culvert waterproofing, in particular to an assembled culvert splicing waterproofing device. Background Art

[0002] A culvert refers to a drainage channel (water passage) built under the roadbed and below the road surface during highway construction in order to allow the highway to pass through the canal smoothly without hindering traffic. This structure allows water to flow under the highway.

[0003] It is used to drain flood water across natural valleys and depressions, or to cross roads of all sizes as a traffic thoroughfare for people, livestock and vehicles, or as a canal for farmland irrigation.

[0004] As an important water conservancy facility, culverts are mainly used for drainage, irrigation and other purposes. During the construction and use of culverts, the joints of culverts need to be put back. For assembled culverts, the joints are the key parts of waterproofing. Since there may be gaps at the joints, which can easily lead to water penetration, waterproof membranes, sealing strips, etc. should be used to waterproof the joints.

[0005] The culvert joint refers to the connection between two or more sections of culvert pipes in a prefabricated culvert.

[0006] During the construction of prefabricated culverts, in order to facilitate transportation and installation, the culvert is usually divided into several sections, and then these sections are spliced ​​together at the construction site to form a complete culvert.

[0007] Therefore, the culvert joint is an important component of the prefabricated culvert, and its performance directly affects the overall quality and service life of the culvert.

[0008] At present, when the culverts of adjacent culverts are extended, they are mostly in the form of splicing. In order to ensure a certain waterproof effect, the joints are fixed by welding. However, the welding points are easily corroded by the moisture in the soil and other environments for a long time, and are prone to cracking and damage. This can easily cause water seepage at the joints of the culverts. Therefore, it is necessary to waterproof and reinforce the joints of adjacent culverts to improve the safety of culvert use.
