Description

Technical Field

[0001] The utility model relates to the technical field of waterproofing for shield machine construction, in particular to a waterproofing device for a shield machine exit hole. Background Art

[0002] A shield machine is a tunnel boring machine that uses the shield method. Shield machines are widely used in underground engineering operations. The shield construction method is that the tunnel boring machine constructs (lays) the "shield" (referring to the supporting segments) of the tunnel while excavating. It is different from the open construction method. Waterproofing of the shield machine entering the hole has always been a focus issue.

[0003] Folding pressure plates and rubber curtains have been widely used in the waterproofing of shield machine exit holes, but folding pressure plates are generally fixed to the structural wall with bolts. When the shield machine exits the hole, there is a general posture deviation problem. In order to achieve good water-stopping measures, it is necessary to manually adjust the position of each folding pressure plate, which consumes a lot of manpower and reduces construction efficiency.

[0006] Preferably, pin sleeves are installed on both the fixed plate and the flap, and a pin shaft is installed between the pin sleeve of the fixed plate and the pin sleeve of the flap.

[0007] Preferably, a movable hole is opened on the surface of the movable plate, and the inner wall of the movable hole is connected to the surface of the steel strand.

[0008] Preferably, the diameter of the movable hole is larger than the diameter of the steel strand.

[0009] Preferably, the movable plate and the flap are both made of steel plates, and the movable plate is welded to the surface of the flap.

[0010] Preferably, one end of the steel strand is fixedly mounted on a steel cable fastener, and the other end of the steel strand passes through a tensioning hole in the steel cable fastener.

[0011] Preferably, the fixed guide rail seat of the guide rail is installed on a circular ring plate, and the fixed plate is installed on a sliding member of the guide rail.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The shield machine tunnel exit waterproof device is provided with steel strands, steel cable fasteners, guide slide rails and movable plates. The fixed plate is connected to the circular ring plate through the guide slide rails so that the fixed plate can slide. The fixed plate is connected to the flap through the cooperation of a pin sleeve and a pin shaft. The flap is rotatably connected to the fixed plate. The steel strands pass through the movable holes of the movable plate. The steel strands apply annular pressure to the flap so that the flap is kept in close contact with the window cloth rubber plate, thereby ensuring the sealing effect between the window cloth rubber plate and the shield segment, avoiding continuous adjustment of the position of each folding pressure plate, and improving construction efficiency.
