Air bag type sealing structure for deformation joint of open trench tunnel
The invention discloses an air bag type sealing structure for a deformation joint of an open trench tunnel. A groove along the whole circle of the inner wall of the tunnel in the circumferential direction is formed in the position, with the deformation joint, of the inner wall of the tunnel; the deformation joint is filled with filling materials; the open end of the groove is provided with a baffle fixed to the inner wall of the tunnel, and an air bag type waterstop is arranged in the groove; and the air bag type waterstop is provided with an inflation valve penetrating out of the baffle. Because the back-loading type waterstop is adopted, the air bag type sealing structure is not limited by the conditions on a construction site, high-standard protection on the site is not needed, and meanwhile, the air bag type sealing structure for the deformation joint is also applicable to fault rectification of an existing tunnel; the air bag type waterstop can be replaced without influencing the use functions, and the request for durability is met; and a uniform air pressure monitoring system and an automatic inflation system can be built to form an intelligent waterproof system with an automatic maintenance function.
