Row excavates.The housing of the cylinder component is shield, plays a part of temporary support to the also unlined Tunnel Section excavated,
Water And Earth Pressures around are born, and completely cut off underground water.The operations such as excavation, casting, lining cutting are carried out under the supporting of shield.On ground
In the iron shield launching stage, shield machine lifting is transferred into end well after the completion of the structural sections construction of End Shaft at Underground Metro Station
In, and reaction frame is established in end well, the negative ring of the first ring support, shield machine are first set up between reaction frame and shield machine shield tail
When originating driving, the jack apical grafting in shield machine makes shield machine integrally move forward on the side that the first ring supports negative ring
Certain distance, the jack in shield machine main body are retracted, and then, check whether shield machine driving axis is deposited with Tunnel Design axis
,, be to the second ring when the first ring supports the front of negative ring to carry out the assembly of the negative ring of the second ring support if deviation be present in deviation
The axis of the negative ring of support is adjusted, and after the negative ring cyclization of the second ring support, the jack in shield machine main body stretches out again, apical grafting
On the side that the second ring supports negative ring, shield machine is integrally continued to move along certain distance, shield is corrected in moving process
The driving axis of structure machine, makes it be consistent with Tunnel Design axis, so repeatedly, until shield machine shield tail enters tunnel portal
It is interior, so as to complete adjustment and the structure that shield launching steel pipe sheet bears ring support system.In whole negative member ring systems structure, existing skill
The negative ring of art forms closed loop, in the adjustment structure of negative ring support system using armored concrete prefabricated pipe section in end well
During building, due to concrete pipe sheet limited strength, broken and damage easily occurs in adjustment process, directly results in negative annulate shaft
The Adjustment precision of line is low and adjustment is difficult, has influence in follow-up tunneling process, the assembled quality of positive ring and the control of tunnel axis
System.In addition, when negative ring meets dismounting condition, dismantling concrete bears ring support section of jurisdiction, and broken, damage ask also easily occurs
Topic, the cycling and reutilization of next time is had influence on.
The content of the invention
The utility model provides a kind of shield launching steel pipe sheet and bears ring support system, solves existing negative ring concrete
Section of jurisdiction limited strength, broken and damage technical problem easily occurs in the adjustment of negative ring support system and structure.
The utility model is that solve above technical problem by the following technical programs:
A kind of shield launching steel pipe sheet bears ring support system, including starting end head well, is fixed in the rear end of starting end head well
Reaction frame is provided with, diagonal brace is provided with the rear end face of reaction frame, the first semi-ring is provided with the front end face of reaction frame and is born
Endless tube piece, born in the first semi-ring and the negative endless tube piece of the second semi-ring is provided with the leading flank of endless tube piece, endless tube piece is born in the second semi-ring
Leading flank on be provided with the 3rd semi-ring and bear endless tube piece, set between the second semi-ring bears endless tube piece and the 3rd semi-ring bears endless tube piece
There is the semi-ring pose adjustment steel plate washer that the 3rd semi-ring bears endless tube piece.
The second semi-ring bear be disposed with front side of endless tube piece the 3rd semi-ring bears endless tube piece, the 4th semi-ring bears endless tube piece,
5th semi-ring bears endless tube piece and the 6th semi-ring bears endless tube piece, and the first full ring is provided with the leading flank of the negative endless tube piece of the 6th semi-ring and is born
Endless tube piece, born in the first full ring and the second full ring is provided with endless tube piece leading flank bears endless tube piece, the first full ring bear endless tube piece with
Second full ring is provided with the full ring pose adjustment steel plate washer that the second full ring bears endless tube piece between bearing endless tube piece, and ring is born in the first full ring
Split heads shape support frame is provided between the trailing flank upper end of section of jurisdiction and reaction frame.
The utility model utilizes pose adjustment steel plate washer, and pad is connected between two adjacent negative ring steel tunnel segments, can larger amplitude
Deviation caused by the negative endless tube piece axis of degree regulation and shield machine axis, realizes shield machine and shield is remained during reach
The structure machine driving axis steel tunnel segment lighter in weight consistent and hollow with negative endless tube piece axis, it is easy to hang assembly and disassembly, can follow
Ring repeatedly utilizes, and effectively reduces construction cost, improves efficiency of construction, reduces construction risk.
