Background

In-line pipelines for transporting oil, gas and water supply lamps are generally made of plastic, steel or ball-milled cast iron, and such pipelines are generally buried underground. In the laying process of pipelines, the traditional underground pipeline construction method needs to excavate the ground for laying, and the influence on the environment is great. Pipeline laying is currently commonly performed using trenchless underground pipeline construction techniques. The trenchless underground pipeline construction technology is a construction technology for laying, repairing and replacing underground pipelines and cables under the condition that a groove is not dug in the ground, does not damage the environment, does not block traffic, does not disturb residents, and is high in construction speed. However, due to the weak foundation or the corrosion of the lamp, the pipeline is easily damaged by aging, cracks and the like, and needs to be repaired in time.

For example, chinese patent with publication number CN207438023U discloses a local repair tool for trenchless pipelines, which includes a cylinder made of elastic material, wherein two ends of the cylinder are respectively connected with end caps in a sealing manner, and the cylinder and the end caps at the two ends together enclose a tensioning cavity; one end cover is provided with a pressurizing joint communicated with the tensioning cavity; at least three guide rails which are uniformly distributed in an annular shape are distributed on the end face of each end cover, the guide rails are arranged along the radial direction of the end cover, walking wheels are connected on the guide rails in a sliding mode, clamping devices are arranged at the joints, and the outmost sides of the walking wheels extend out of the edges of the end covers. The structure can conveniently repair the corresponding position of the prefabricated pipeline repairing lining in the pipeline and repair the pipeline. However, because the end covers at the two ends of the tensioning cavity are fixed in size, when the end covers are much smaller than the pipeline to be repaired, when the tensioning cavity is supported, the middle part is most bulged, and the phenomenon that only the middle part of the pipeline repairing lining in the tensioning cavity is compressed, and other parts cannot compress the repairing lining well easily occurs.
