Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an outdoor buried prefabricated concrete water supply and drainage ditch. Background Art

[0002] During the water supply and drainage construction process, the drainage main and water supply main need to be arranged below the ground. The drainage main is used to collect multiple building drainage outlet pipes, and the water supply main is used to collect multiple water supply branches or risers in a single building.

[0003] For example, the utility model with application number 202321794885.8 discloses a prefabricated finished concrete water supply and drainage trench for outdoor burial, which has the advantages of reducing the number of inspection wells for discharge pipes, improving the efficiency of external network construction, and the centralized pipe gallery form is conducive to later operation and maintenance. The water supply and drainage trench is a small trench, and the external network water supply and drainage pipelines are centrally installed, which can reduce the external network construction work and modularly integrate some external network pipelines. Drainage pipes and water supply pipes are laid in the trench, and the drainage pipes and water supply pipes are fixed by side pipe fixings and bottom pipe fixings. The drainage pipes in the trench are used to collect multiple building drainage outlet pipes, and the water supply pipes in the trench are used to collect multiple water supply branches or risers in a single building. When the trench is buried outdoors, drainage inspection wells and valve wells may not be set, and factory prefabrication can be achieved, which can meet the needs of rapid construction and facilitate later maintenance and repair. The use of prefabricated trenches effectively improves the construction period of outdoor water supply and drainage pipelines, and is suitable for various types of construction projects.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This kind of prefabricated finished concrete water supply and drainage trench used for outdoor burial needs to be coated with a layer of mud at the connection position when it is spliced ​​and installed to improve the fixing effect of the connection position and the waterproof sealing effect. However, the connection surface coated with only a layer of mud at the connection is weak, and not only the fixing effect is poor but also the sealing is poor.

[0006] For this purpose, an outdoor buried precast concrete water supply and drainage trench is designed to optimize the above-mentioned problems. Utility Model Content
