Abstract
The invention provides a device and a method for blocking a connecting place between pipes of a shield tunneling machine. The device comprises a blocker and a hydraulic cylinder which is concentrically arranged with the blocker, wherein the size of the periphery of the blocker is matched with a primary pipe; the blocker comprises a high-pressure air pipe joint, sealing brushes, a sealing air bag and sealing rubber; the sealing brushes are distributed at the two ends of the blocker; the sealing air bag is positioned in the middle position of the blocker; the sealing rubber is positioned between the sealing brushes and the sealing air bag; and the high-pressure air pipe joint is connected to the pipe and provides high-pressure air for the sealing air bag by an air hole. When the pipe, a prolonging pipe or other pipes required to be opened are required to be replaced to repair, the blocker equipment is conveyed to the connection place of the pipe through pushing force of the hydraulic cylinder, and outward pushing force generated by a residual liquid loop in the pipe is compensated by the friction force between the air bag expanded under pressure and the pipe wall, so that the pipes are sealed.
