Description

Technical Field

[0001] The utility model relates to the technical field of shield tunnel construction, in particular to an emergency plugging device for water leakage caused by damaged corners of a formed pipe segment. Background Art

[0002] Generally speaking, water and sand gushing caused by corner loss and damage of formed tunnel segments need to be filled and sealed with cotton yarn and wooden wedges, and then polyurethane or double liquid slurry is injected at the two rings after the damage. After there is no water leakage, the segment repair and other subsequent treatments are carried out.

[0003] In coastal areas, under the geological conditions of soft soil and rich water, if the pipe segments are severely damaged and affected by pressurized water, cotton yarn and wooden wedges cannot effectively seal them, resulting in large amounts of soil and water loss behind the wall in a short period of time and uneven stress on the pipe segments. In severe cases, accidents such as ground collapse and tunnel flooding may occur. Utility Model Content

[0007] Bolts are inserted into the bolt holes, and the bolts are connected to the formed tube segments so as to press the curved panels against the damaged areas;

[0008] Injection and discharge pipe, the arc-shaped panel is provided with a perforation, the end of the perforation away from the formed tube sheet is connected to the injection and discharge pipe, and the injection and discharge pipe is installed with a ball valve.

[0009] Furthermore, the number of the bolt holes is four, and the four bolt holes are respectively arranged at the four corners of the curved panel.

[0010] Furthermore, the perforation is arranged at the plane center of the curved panel.

[0011] Furthermore, an elastic sealing strip is bonded to the outer curved surface of the curved panel. The elastic sealing strip is arranged in a circle along the circumferential direction of the curved panel. The elastic sealing strip is pressed against the inner wall of the formed tube segment.
