Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a connector mechanism for a shield tunnel connecting passage. Background Technology

[0002] In shield tunnel engineering, connecting passages are often required between two main tunnels to meet the needs of personnel passage, equipment installation, pipeline laying, and emergency evacuation. The construction of these connecting passages usually involves complex construction procedures, especially when excavation and support are carried out inside or near existing tunnels. This not only makes construction difficult and time-consuming, but also poses potential risks to the stability of the main tunnel structure.

[0003] With the continuous development of tunnel engineering technology, higher requirements have been placed on the rapid, safe, and convenient construction of connecting passages. Currently, the construction of connecting passages mostly employs traditional techniques such as mining methods, freezing methods, or grouting reinforcement methods. These methods generally suffer from low construction efficiency, significant environmental impact, and high costs. Especially in projects with special geological conditions or strict construction schedule requirements, traditional methods of constructing connecting passages often fail to meet engineering needs.

[0004] Therefore, a shield tunnel connecting channel connector mechanism is needed to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a connector mechanism for a shield tunnel connecting passage to solve the problems mentioned in the background art.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model achieves rapid and convenient connection between channel structural units through the cooperation of upper and lower shells and a unique plug-in strip and plug-in groove structure. This avoids the complex on-site excavation, support and pouring procedures in traditional methods, greatly shortens the construction cycle of connecting channels, improves construction efficiency, and is especially suitable for engineering environments with tight schedules or limited space;

[0018] 2. This utility model, through the coordinated operation of the inner docking structure and the connecting structure, not only ensures the tight interlocking of the upper and lower shells, but also provides additional stable support.
