The New Taipei City Tourism and Tourism Bureau issued a news on the 26th, stating that the Shen-ao Tunnel has a long history, coupled with frequent earthquakes and a humid environment, and cracks appear in the wall. Ride a rail bike in the tunnel.
The Tourism Bureau said that this time, for different crack conditions, corresponding repair methods were adopted: the cracks that do not affect the safety of the structure are filled with non-shrinking cement. Because the tunnel is old and affected by earthquakes, the wall is partially surrounded by cracks. Concrete blocks , Use double-layer carbon fiber patch to repair to prevent the concrete block from peeling off; in more serious places, it is reinforced with annular steel plate to stabilize irregular oblique cracks, which is also the largest and most difficult project in the project.
Supervisor Wu Yingjie said that the biggest difficulty in the repair project is that the tunnel wall is curved and the structure is uneven. Therefore, repeated revisions are required when installing steel plates so that there are no gaps between the steel plates.
In addition, due to the limited space in the tunnel, large-scale equipment cannot be used, and only manual cranes and manpower can be used to hoist and install steel plates.
