Problems solved by technology

[0003] The traditional shield communication channel is constructed after two tunnels or one tunnel are penetrated. Usually, the well-shaped steel support is used for stability. After the well-shaped steel support, it is inconvenient for construction personnel and materials to enter and exit the tunnel, which prolongs the construction period. At the same time, This kind of steel support structure is mostly welded and installed, the installation efficiency is low, and it is difficult to dismantle after the tunnel construction is completed, which further prolongs the construction period

Embodiment 1

[0041] Such as figure 1 , figure 2 and image 3 As shown, a segment support structure for the connecting channel of a shield interval tunnel includes a segment ring assembled from six segments 1 and a ring-shaped steel support structure circumferentially surrounding the inner side of the segment ring, wherein, The six segments 1 consist of three standard blocks, two connecting blocks and one capping block;

[0042] The inner middle part of the segment 1 has an assembly screw hole 6, and corresponding to the assembly screw hole 6, an assembly bolt 3 threaded therewith is provided;

[0043] The ring-shaped steel support structure includes arched steel support pieces 2 having the same number as the segments 1, and the adjacent arched steel support pieces 2 are detachably connected;

[0044] The middle part of each arched steel support piece 2 is provided with a via hole corresponding to the assembly bolt 3, and the arched steel support piece 2 is screwed into the correspondin...

Embodiment 2

[0056] The difference with embodiment 1 is:

[0057] Such as Figure 4 and Figure 5 As shown, the telescoping mechanism includes a rubber airbag 11, and the outer side of the arched steel support piece 2 and the end of the through hole close to the tube piece 1 are provided with a counterbore 10, and the arched steel support piece The inner side wall of 2 is provided with a through hole 12 communicating with the receiving counterbore 10, and a gas pipe is provided through the through hole 12, one end of the gas pipe is connected to the rubber air bag 11, and the other end can be connected to an external gas source.

[0058] Preferably, two rubber airbags 11 are provided, and are respectively located on opposite sides of the accommodating counterbore 10, and two through-holes 12 are correspondingly opened on the inner wall of the arched steel support sheet 2. .

[0059] The assembly and disassembly method of the present invention: during installation, after using the assemb...

Abstract

The invention discloses a shield interval tunnel connection channel segment supporting structure. The shield interval tunnel connection channel segment supporting structure comprises a segment ring formed by splicing a plurality of segments and an annular steel supporting structure connected around the inner side of the segment ring in the circumferential direction. Splicing screw holes are formedin the middles of the inner sides of the segments, and splicing bolts in threaded fit with the splicing screw holes are arranged corresponding to the splicing screw holes. The annular steel supporting structure comprises arched steel supporting pieces with the number consistent with that of the segments, and every two adjacent arched steel supporting pieces are detachably connected. Via holes areformed in the positions, corresponding to the splicing bolts, of the middles of the arched steel supporting pieces, and the arched steel supporting pieces penetrate through the via holes through thesplicing bolts to be screwed into the corresponding splicing screw holes to be detachably connected with the corresponding segments. Telescopic mechanisms are arranged between the arched steel supporting pieces and the corresponding segments. The shield interval tunnel connection channel segment supporting structure is simple in structure and convenient and fast to assemble and disassemble, constructors and materials can enter and exit conveniently, and the construction period of a shield connection channel is effectively shortened.

Description

technical field [0001] The invention relates to the technical field of tunnel shielding, in particular to a segment support structure of a tunnel connecting channel in a shield section. Background technique [0002] The shield connection channel is generally set in the middle of two tunnels, and becomes a channel set between the two tunnels, which plays the roles of communication, drainage and fire prevention. If there is a problem with one tunnel as a whole, pedestrians / constructors can transfer to another tunnel through the connecting passage, and the safety factor of pedestrians / constructors will also be greatly increased, so it is called "escape channel". It is also convenient that when a problem occurs in a tunnel, rescuers can reach the communication channel from another tunnel, and then enter the place that needs rescue (the tunnel where the accident occurred) through the communication channel, so as to achieve the purpose of quick rescue. [0003] The traditional sh...
