Background
As cities develop, urban ground traffic pressure is increasing. All major cities are dedicated to developing underground rail transit, and shield tunneling is mostly adopted to construct underground tunnels in the cities. The main cause of water leakage occurs at the joints and bolt holes as the shield tunnels penetrate water-bearing formations. When the condition of water leakage appears in the seam, a water seepage channel is formed in the gap between the bolt hole and the bolt, and great hidden danger exists for the structural safety. At present, a segment bolt gasket is mostly adopted for interface waterproofing, a bolt rubber gasket is additionally arranged at an interface, and water in a gap between a bolt hole and a bolt is prevented from leaking to the inside of a tunnel. The conventional bolt washer only plays a role in preventing leakage water from entering the interior of the tunnel, but neglects the fact that the bolt is exposed in water in the water seepage channel, and does not effectively prevent the corrosion of the leakage water to the bolt body. If can guarantee that the bolt obtains omnidirectional waterproof protection in the bolt hole. Even if groundwater leaks into the bolt hole from the joint, the bolt is not brought into direct contact with water to increase the risk of rusting the bolt.
