Description

Technical Field

[0001] The utility model relates to the technical field of guide rails, in particular to an adjustable support guide rail. Background Technique

[0002] The pipe jacking construction technology is a non-excavation pipe-laying construction technology used for municipal construction. Its advantages are that it has little or no impact on the surrounding environment, requires a small construction site, produces little noise, and can operate deep underground, which is an incomparable advantage of the excavation and buried pipe method. In pipe jacking construction, in order to ensure that the pipe jacking pipe joints can be jacked in according to the designed elevation, axial direction and slope, it is necessary to install support guide rails at the bottom of the working pit for placing and guiding the pipes. Through the accurately installed guide rails, construction workers can ensure that the pipes do not deviate from the predetermined path during the jacking process, thereby ensuring the construction quality of the pipe jacking project. The guide rails also undertake the important task of supporting the pipe sections that have not entered the soil. During the jacking process, the front end of the pipe needs to be stably supported to prevent deformation or damage caused by uneven stress. The stability of the guide rails is of great significance for maintaining the straightness of the pipes and reducing the jacking resistance. Therefore, the existing support guide rails for pipe jacking construction generally adopt a fixed structure and need to be disassembled and repositioned according to the construction progress. Frequent disassembly operations will take up a lot of working time. For this reason, we propose an adjustable support guide rail. Content of the Utility Model
