Abstract

The invention discloses a watertight device of a heating machine for passing in and out a door opening. The watertight device is used for a working well which is provided with an enclosure structure, the enclosure structure is provided with the door opening, the watertight device comprises a freezing pipe for injecting a refrigerant, the freezing pipe is partially or fully wound around the inner wall of the door opening, and the enclosure structure is also provided with a grouting pipe communicated with the space encircled by the freezing pipe. The invention also discloses another watertight device of the heading machine for passing in and out an door opening, wherein the watertight device is used for a working well which is provided with an enclosure structure, a lining structure is arranged at the inner side of the enclosure structure and provided with the door opening, the watertight device comprises a freezing pipe for injecting a refrigerant, the freezing pipe is partially or fully wound around the inner wall of the door opening, and the lining structure is also provided with a grouting pipe communicated with the space encircled by the freezing pipe. On the premise of meeting watertight requirement on the heading machine for passing in and out the door opening, the invention fully utilizes the space of the enclosure structure or the lining structure to reduce or avoid the internal working well space occupied by the watertight device for passing in and out the door opening.
