Description

Technical Field

[0001] The utility model relates to the technical field of cable protection structures for drilling and over-the-counter construction, in particular to a cable protection structure for drilling and over-the-counter construction. Background Art

[0002] The cable protection structure of drilling and crossing construction is mainly to ensure that the cables are not damaged during the construction process and to ensure their long-term stable operation. The cable protection structure of drilling and crossing construction is an important aspect of power line construction, especially when it involves drilling and crossing complex environments such as railways, roads or rivers. The protection of cables is particularly critical. Appropriate protection structures can effectively alleviate these risks and ensure the integrity of cables. Through reasonable design and strict construction management, cables can be effectively protected to ensure the safe and stable operation of the power system. This is not only related to the reliability of power supply, but also to the quality of life of the majority of users and the normal progress of economic activities.

[0003] In the existing technology, when protecting cables, it is necessary to install a protective tube on the outside of the cable. However, during the drilling construction process, passing the outer protective tube through the steel pipe will cause damage to the protective tube. There will be huge friction when the outer protective tube passes through the inside of the steel pipe, causing the outside to be worn, resulting in shaking after installation, and instability between adjacent pipes, affecting the normal use of the cable in the future.

[0004] Therefore, this patent proposes a cable protection structure for drilling and through-hole construction in which the outer protective tube can be retracted into the steel pipe and reduce wear during the entry process, to solve such problems. Utility Model Content
