Description

Technical Field

[0001] This utility model relates to the field of tunnel construction equipment technology, and in particular to a locking anchor pipe positioning device. Background Technology

[0002] Anchor pipes are temporary or permanent reinforcement components used in tunnel, foundation pit support, or slope engineering to enhance structural stability. They are usually used in conjunction with steel arches, shotcrete, etc. Their main function is to prevent slippage, settlement, or deformation of the support structure's foot, thus ensuring construction safety.

[0003] To adapt to different construction conditions, the angle requirements for anchor pipes vary. To achieve adjustable angle flexibility, positioning devices for anchor pipes have emerged. For example, patent CN220302162U describes an anchor pipe positioning device for tunnel construction. This device can change the insertion angle according to actual conditions, improving its applicability and making it more suitable for different scenarios. However, in actual construction applications, the use of a loose-tight connection makes the anchor pipe and positioning device prone to loosening, leading to stress transfer failure. Therefore, a stable anchor pipe positioning device that can meet various on-site requirements is needed. Utility Model Content
