Background
With the development of urbanization, underground spaces such as urban underground traffic, urban pipe corridors and the like are increasingly developed. Wherein shield tunnel obtains extensive application in underground space construction, and shield tunnel is by the assembled structure that section of jurisdiction and connecting bolt constitute, therefore there are transversal joint and longitudinal joint in the shaping pipe ring, when section of jurisdiction seam emergence infiltration, causes very big threat to the security of tunnel segment structure.
At present, a shield tunnel segment seam waterproof system mainly comprises two aspects: 1. a single-channel or double-channel sealing gasket waterproof system, and a segment caulking waterproof system. Wherein, sealed waterproof system of filling up mainly comprises seal groove and sealed the pad, and sealed waterproof ability is mainly greater than outside design water pressure through waterproof sealing pad compressive contact stress and judges, and when the section of jurisdiction seam takes place to open wrong platform or sealed ageing to lead to sealed pad contact stress can't satisfy design water pressure, then sealed waterproof system of filling up became invalid. The segment caulking waterproof system consists of a segment caulking groove and a sealing material, wherein the segment caulking groove is a notch formed in the inner edge of the segment, and the sealing material, such as unformed building sealant or a formed ethylene propylene diene monomer synthetic sealing element and the like, is filled in the notch, so that the water stopping and draining effects of the segment caulking are realized.
Above-mentioned shield tunnel waterproof system lacks the design to section of jurisdiction seam bolt hole stagnant water, and when section of jurisdiction seam sealed pad waterproof system became invalid, the infiltration leads to the tunnel to take place the infiltration problem along section of jurisdiction seam face inflow bolt hole to according to the statistics of the phenomenon of seeping water during tunnel operation, the discovery bolt hole position has the route of seeping water. Therefore, the engineering field needs to solve the problem of water seepage of the bolt holes of the shield tunnel segment.

Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
The invention will now be further elucidated with reference to the drawings described above.
The invention discloses a waterproof sealing method for a shield tunnel bolt hole, which comprises the following steps:
(1) slotting the position of the bolt 3 of the shield segment 5, and roughening the inner wall of the sealing groove 2;
(2) coating the gasket thread 11 surface on the outer side wall of the bolt hole sealing gasket 1 with a sealing glue, and leading the sealing glue into the sealing groove 2 and buckling the sealing groove 2;
(3) bolts 3 penetrate through the inner wall surfaces of the bolt hole sealing gaskets 1 on two sides between the shield segments 5;
(4) and (5) tightly jacking the end face of the bolt hole of the shield segment by using a nut 4.
As shown in fig. 1, when the bolt hole sealing gasket 1 is used in the present invention, the waterproof system for the joint of the tunnel segment 5 includes a gasket waterproof system mainly including a gasket 6, a bolt hole waterproof system mainly including the bolt hole sealing gasket 1, and a caulking waterproof system mainly including a caulking 7. Wherein novel shield tunnel bolt hole waterproof sealing device mainly comprises bolt hole seal ring 1 and seal groove 2, bolt hole seal ring 1 pastes on seal groove 2 surface at sealed gluey brute force, and when section of jurisdiction hand hole department construction bolt, bolt 3 passes the gasket hole 10 of bolt hole waterproof system, is fastening through nut 4 and realizes the connection between the section of jurisdiction. The design size of the bolt hole sealing washer 1 corresponds to the diameter of the bolt, so that the design size is not limited to the case, and the size suitable for actual project engineering can be determined according to actual engineering and construction site conditions.
As shown in figures 2 and 4, the bolt hole sealing washer 1 in the novel waterproof sealing device for the shield tunnel bolt hole is composed of water-swelling rubber 8 and ethylene propylene diene monomer 9, the water-swelling rubber 8 and the ethylene propylene diene monomer 9 are extruded and formed through a microwave vulcanization technology, a washer hole 10 is reserved in the middle of the bolt hole sealing washer 1, and the size of the washer hole 10 corresponds to the diameter of the bolt 3. Bolt hole seal ring 1 thickness is a little higher than 2 heights of seal groove, and bolt hole seal ring 1 compression is in seal groove 2 after tunnel segment 5 is assembled, helps strengthening bolt hole local rigidity on the one hand, and on the other hand is of value to the waterproof ability who proposes bolt hole seal ring 1 contact surface. When the sealing gasket 6 is in water-proof failure, seepage water flows through the gasket hole 10, and the water-swelling rubber 8 expands to increase the contact stress with the wall surface of the bolt 3, so that the water-proof effect is achieved.
The outside of the bolt hole sealing washer 1 is distributed with washer threads 11, such as the side view of the bolt hole sealing washer 1 shown in fig. 2, the gluing area of the side wall of the bolt hole sealing washer 1 and the sealing groove 2 is mainly increased by increasing the washer threads 11, the bolt hole sealing washer 1 is separated when the bolt 3 is not installed, and in addition, the water seepage of the outside contact surface of the bolt hole sealing washer 1 is prevented.
