Description
Technical field
The utility model is related to applied in shield method Freezing Method for Cross-passage Construction with main tunnel connecting position at service channel
Steel pipe sheet.
Background technology
One kind is disclosed in the application for a patent for invention file that application publication number is CN106948833A, and " pin-connected panel contact is logical
Road structure and construction method ", shield method get in touch with can road construction in, for the service channel at main tunnel connecting position
Steel pipe sheet is using structure shape as shown in fig. 4 a, and every steel pipe sheet is the identical conventional cylindrical section steel pipe sheet 11 of structure, assembled
Complete cycle is in cylindrical tube afterwards, and Fig. 4 b show the connecting position in main tunnel 21 and service channel 22 using this cylindrical section steel pipe sheet
The structure type at place；In order to make the structure of service channel 22 not invade main tunnel boundary, after the completion of service channel 22 tunnels, need
The part service channel steel pipe sheet in main tunnel and service channel joint area is cut off in the radian in the hole tunnels Nei Anzhu 21, such as schemed
Cut-out 12 shown in 4b.But in site operation, since work surface is narrow, hole internal cutting process work efficiency is very low, operation wind
Danger is big, it is difficult to ensure construction quality.
Utility model content
The utility model is provided at a kind of and main tunnel connecting position to avoid above-mentioned deficiency of the prior art
Service channel combined steel section of jurisdiction and construction method ensure construction quality to improve construction efficiency.
The utility model is to solve technical problem to adopt the following technical scheme that：
The design feature of the utility model and the service channel combined steel section of jurisdiction at main tunnel connecting position：For with master
Service channel at tunnel connecting position uses combined steel section of jurisdiction, and the combined steel section of jurisdiction refers to by every steel pipe sheet by each
Two parts are set as from the radian fission in the main tunnel of place circumferential location, a part is to be located in service channel to fix section of jurisdiction
Section, another part are the interim section of jurisdiction sections for needing to remove；Straight bolt is utilized between the fixing pipe segment and interim section of jurisdiction section
Implement dismounting.
The utility model and the design feature of the service channel combined steel section of jurisdiction at main tunnel connecting position are lain also in：It will
Seam in the every steel pipe sheet between fixing pipe segment and interim section of jurisdiction section is set as straightway so that by each steel pipe sheet
Complete cycle after fixing pipe segment assembly is connected the polygonized structure to be formed with each straightway.
Compared with the prior art, the utility model has the beneficial effect that：
1, the utility model uses combined steel section of jurisdiction, real using straight bolt between fixing pipe segment and interim section of jurisdiction section
Apply dismounting, it is no longer necessary to be cut off at the scene, greatly improve site operation efficiency, also greatly be beneficial to ensure engineering
Quality.
2, the utility model largely facilitates adding for steel pipe sheet for every steel pipe sheet using straightway approximation circular arc
Work makes.

Specific implementation mode
Referring to Fig. 1, Fig. 2 and Fig. 3, in the present embodiment with the service channel combined steel section of jurisdiction at main tunnel connecting position
Structure type is：Combined steel section of jurisdiction, combined steel section of jurisdiction are used for the service channel 22 at 21 connecting position of main tunnel
Refer to setting every steel pipe sheet to two parts by the radian fission in the main tunnel of respective place circumferential location, a part is position
The fixing pipe segment 23 in service channel, another part are the interim section of jurisdiction sections 24 for needing to remove；Fixing pipe segment 23 with face
When section of jurisdiction section 24 between using straight bolt implement dismounting.
In specific implementation, the seam between fixing pipe segment 23 in every steel pipe sheet and interim section of jurisdiction section 24 is pressed into two-end-point
Position is set as straightway so that by the complete cycle after 23 assembly of fixing pipe segment in each steel pipe sheet is to connect to being formed with each straightway
Trisection line polygonized structure, using the circular arc in the close main tunnel of the polygon of proximal segment line, using trisection line compared with circular arc point
From design, can be very big simplified making work section, reduce cost of manufacture, the machining accuracy of conventional steel pipe piece can be met the requirements.
The utility model can greatly improve construction efficiency, reduce site operation amount, improve site operation environment, reduce
Operating risk.
In work progress, it is attached, is made using straight bolt first between fixing pipe segment 23 and interim section of jurisdiction section 24
Its entirety is rendered as conventional cylindrical section steel pipe sheet, and assembled, tunneling construction is carried out using usual manner for cylindrical section steel pipe sheet
When completion, portal interface implements closure and joint weld by construction requirement, completes entrance construction；Then, it is hung in tunnel top
Chain block tenses interim section of jurisdiction section 24 using chain block, removes the straight bolt in corresponding interim section of jurisdiction section 24, completion group
The dismounting of section of jurisdiction is closed, ensures that service channel section of jurisdiction does not invade shield tunnel limit.
