Problems solved by technology

It can be seen from this that the water stop device for the entry and exit of the tunneling machine does not make reasonable and effective use of the width of the enclosure structure or lining structure, and occupies a lot of internal space in the working well, so that other construction operations are affected, and even need to be enlarged. work wells, thereby increasing the cost

Embodiment 1

[0048] see figure 1 with figure 2 The utility model relates to a water stop device for entering and exiting holes of a boring machine, and the water stop device is used for working wells. The working well is provided with a protective structure, and the protective structure has a door opening. The water stop device includes a freezing pipe 12 for injecting refrigerant, and part or all of the freezing pipe 12 is placed around the opening of the door. On the inner wall, the enclosure structure is also provided with a grouting pipe communicating with the space enclosed by the freezing pipe.

[0049] The working well is divided into an originating well and a receiving well. In this embodiment, the working well is an originating well. The outer end of the enclosure structure 2 is provided with a reinforced foundation 10 .

[0050] In this embodiment, a ring 11 for positioning the boring machine is fixed inside the door opening, and the inner wall of the door opening is the inner ...

Embodiment 2

[0072] The difference between this embodiment and embodiment 2 is that please refer to Figure 6-8 , the working well is a receiving well. The entry and exit hole water stop device of the boring machine is a water stop device for the entry and exit of the boring machine, and the side of the freezing pipe 12 away from the enclosure structure 2 is provided with a sealing door 4 . The door closure 4 is fixed at the door opening of the enclosure structure 2 through the door sealing support structure 5 for blocking the door opening. Image 6 Shown is a structural schematic diagram of the situation where the freezing pipe 12 is arranged at the rear of the inner wall of the door opening of the enclosure structure 2 . Figure 7 Shown is a structural schematic diagram of the situation where part of the freezing pipe 12 is arranged in the door opening of the enclosure structure 2 . Figure 8 Shown is a structural schematic diagram of the case where the longitudinal width of the freezi...

Embodiment 3

[0074] Please refer to Figure 6-Figure 8 , this kind of water-stopping device for the entry and exit of the excavating machine, the water-stopping device is used for the working well, the working well is provided with an enclosure structure 2, the inner side of the enclosure structure 2 is provided with a lining structure 3, and the inner The lining structure 3 has a door opening, the water stop device 1 includes a freezing pipe 12 for injecting refrigerant, part or all of the freezing pipe 12 is placed around the inner wall of the door opening, and the lining structure 3 is also provided with A grouting pipe 14 communicating with the space enclosed by the freezing pipe 12 .

[0075] In this embodiment, the working well is a receiving well. The entry and exit hole water stop device of the boring machine is a water stop device for the entry and exit of the boring machine, and the side of the freezing pipe 12 away from the enclosure structure 2 is provided with a sealing door ...

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 meetingwatertight 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 theinternal working well space occupied by the watertight device for passing in and out the door opening.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a water-stopping device for tunnel entry and exit. Background technique [0002] There are two key procedures in existing pipe jacking and tunnel construction: going out of the starting shaft and entering the receiving shaft. These two key processes all involve the setting of the water stop device. [0003] Existing water-stop devices for tunnel entry and exit, such as patent application No. 200910055382.7 with an application date of July 24, 2009, discloses a water-stop device for tunnel entry and exit, including at least one water-stop for front and rear openings A casing, the water-stop casing is arranged at the periphery of the door opening of the enclosure structure, and the water-stop casing is sealed and fixedly connected with the enclosure structure, and the water-stop casing includes: a casing with front and rear openings The casing and the freezing pipe for inject...
