Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a rapid prototyping tool for concrete pipe strips. Background Art

[0002] In the current drainage system, underground pipes generally use ductile iron pipes or prefabricated reinforced concrete pipes. To ensure the sealing of the pipe interfaces, not only rubber sealing rings need to be installed, but cement mortar tape must also be applied at the interfaces. There are two main methods in the prior art. One is that workers first install and connect the pipes in the trench, and then dig a working pit at the pipe interface. Due to the limitations of the working environment, workers need to drill into the bottom of the pit, carry mortar buckets, and manually apply mortar to the joints. However, since underground drainage pipes are usually installed in narrow pipe trenches, further digging the working pit makes the working environment worse. Workers working in such an environment not only have limited vision, but also the mortar is easy to fall before solidifying, resulting in the bottom of the pipe joint often not being completely covered by the mortar, thereby seriously affecting the sealing of the joint; the other is that workers use auxiliary tools for construction. For example, Chinese patent CN 216948636 U discloses a pipe interface mortar strip mold. In order to ensure the fluidity of the mortar, the mold often needs to be configured relatively thinly, but this will prolong the drying time of the mortar; on the contrary, if the mortar is configured too thickly to shorten the drying time, some parts may not be fully covered by the mortar.

[0003] Therefore, the existing solutions still cannot fully meet the actual needs of underground drainage pipe interface sealing and aesthetics. It is urgent to develop a concrete pipe strip rapid prototyping tool that is simple to operate, has good sealing performance and high structural strength. Summary of the Invention
