Description

Technical Field

[0001] The utility model relates to the technical field of culvert construction, in particular to a concrete pipe culvert joint. Background Art

[0002] Concrete culvert is one of the most common structures in highway engineering. It mainly plays the role of highway drainage. Compared with slab culvert and box culvert, it is easy to construct and low in cost, so it is widely used.

[0003] Concrete pipe culverts can be constructed by on-site prefabrication or by purchasing finished pipes. Since on-site prefabrication is affected by the prefabrication site and construction level, at present, for small and medium-sized projects, most of them adopt the method of purchasing finished pipe culverts and splicing them on-site for construction.

[0004] Since pipe culverts are generally designed as flat pipes, the construction quality of the pipe culvert joints is particularly important. If the construction is improper, it will cause water seepage at the interface and affect the quality of the entire project. Conventional joints are prefabricated concrete sleeves on the outside of the pipe culvert, but in actual construction, prefabricated concrete sleeves are often difficult to construct and uneconomical, and pipe culvert manufacturers are often unwilling to produce them because they need to customize the template and the quantity is small.
