[0002] In modern water resource allocation projects, after pipeline installation, pressure testing, joint sealing, and internal wall repair are carried out. Taking the water lifting section of the Guangxi Water Resource Allocation Project in the Beibu Gulf as an example, the entire line is 3.3 kilometers long. The outlet pipe from the pumping station uses two 2.4-meter diameter steel pipes. After crossing Provincial Highway S312, two 2.4-meter diameter PCCP pipes are used, which are 1.808 km long. The end line crosses the Zhaiwei Fault Zone and is connected by two 2.4-meter diameter steel pipes. The standard section of the PCCP pipe is 6 meters long, and the standard section of the steel pipe is 12 meters long. After the pipeline installation, pressure testing, joint sealing, and internal wall repair are carried out. Due to the large pipe diameter, a construction platform needs to be erected to ensure that personnel can work safely and conveniently inside the 2.4-meter diameter pipe. In actual construction, it was found that the existing construction platform has poor stability inside the pipeline, and the platform height is inconvenient to adjust, which reduces the safety and efficiency of construction inside the circular pipeline.
[0003] Therefore, there is a need for a platform device that facilitates construction inside circular pipes, enhances the stability of the construction platform, and allows for easy adjustment of the platform's height, thereby improving the safety and efficiency of construction inside circular pipes.
