Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1-4, a novel shield segment joint waterproof sealing pad comprises a waterproof pad 1, wherein an annular groove 2 is formed in the side wall of the waterproof pad 1, an annular strip 3 is embedded in the annular groove 2, the annular strip 3 consists of an annular waterproof strip 302 and an annular expansion strip 301, a small hole 7 communicated with the annular groove 2 is formed in the side wall of the waterproof pad 1, a diaphragm 11 is fixedly connected to the inner wall of the small hole 7, a positioning hole 4 is formed in the side wall of the waterproof pad 1, and an air blowing mechanism for blowing air to the small hole 7 is arranged in the positioning hole 4. It should be noted that, the annular waterproof strip 302 and the annular expansion strip 301 may be spliced together by adopting a thermal welding manner, and the annular waterproof strip 302 is made of a soft rubber material, so that not only can the inner annular expansion strip 301 be protected from water vapor, but also good elasticity is achieved, and when the annular expansion strip 301 swells with water, the annular waterproof strip 302 can also bulge outwards to deform when the annular expansion strip 301 swells outwards. Further, the annular expansion strip 301 can be made of a water-swelling layer material in a novel waterproof gasket for a segment joint of an ultra-high water pressure shield tunnel, which is disclosed in the patent publication No. CN213654872U, and can swell when meeting water.
The air blowing mechanism comprises a pressing plate 5 which is connected in the positioning hole 4 in a sealing sliding manner, the pressing plate 5 is connected to the inner wall of the positioning hole 4 through a spring 6, and the positioning hole 4 is communicated with the small hole 7 through an air guide groove 12. Two connecting gaskets 8 are fixedly connected to the side wall of the waterproof pad 1, and mounting holes 9 are formed in the side wall of the connecting gaskets 8. By arranging the connection pad 8, the connection pad 8 and the connection member of the duct piece can be fixed by mounting, specifically, the connection member of the duct piece and the connection member of the duct piece can be fixed by passing the bolt through the mounting hole 9.
The lateral wall of clamp plate 5 has seted up block groove 13, and block groove 13 interpolation is equipped with locking lever 10. One end of the locking lever 10, which is far away from the engagement groove 13, penetrates through the sidewall of the waterproof pad 1. Specifically, the locking rod 10 and the clamping groove 13 have certain friction resistance, so that the locking rod 10 can be prevented from falling off automatically, the position of the pressing plate 5 is fixed by using the locking rod 10, and the diaphragm 11 is prevented from being broken due to the fact that the pressing plate 5 is touched by mistake in advance.
The diaphragm 11, the annular waterproof strip 302 and the inner wall of the annular groove 2 in the small hole 7 can isolate and protect the annular expansion strip 301 before being arranged in the duct piece, so that the annular expansion strip 301 inside is prevented from being damped and expanded.
