[0002] At the construction site of a nuclear power plant, there will be a lot of construction wastewater, rainwater and other accumulated water discharge. High-density polyethylene (HDPE) wrapped reinforced pipes are needed to discharge the accumulated water. Such pipes generally use socket electric fusion connection. Thermal expansion and contraction will occur during hot-melt connection. Under natural conditions, the hot-melt pipe interface cannot be fully contacted, affecting the tightness of the drainage pipe interface and causing water seepage in the pipe.

[0003] A support device for preventing internal deformation of a pipe is disclosed in the Chinese utility model patent application with the specification CN216692708U. Although it can be applied to internal support of high-density polyethylene wrapped reinforced pipes or other non-metallic pipes, and the support strength is adjustable, thereby achieving a stable support effect inside the pipe, the range of the pipe supported during use is limited, and different support plates cannot be used according to different pipe sizes. At the same time, the support devices all have a single function and cannot be spliced ​​to support each other. Therefore, a support device for preventing internal deformation of a pipe is proposed.
