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 c are shown using this cylindrical section steel pipe sheet in main tunnel 21 and the connecting position of service channel 22
The structure type at place；In order to make the structure of service channel 22 not invade main tunnel boundary, after the completion of the driving of service channel 22, need
The part service channel steel pipe sheet in main tunnel and service channel joint area is cut off in the radian in hole Nei Anzhu tunnels 21, is such as schemed
Cut-out 12 shown in 4c.But in site operation, since work surface is narrow and small, hole internal cutting process work efficiency is very low, operation wind
Danger is big, it is difficult to ensures construction quality.
The content of the invention
The present invention is to avoid the deficiency present in the above-mentioned prior art, there is provided a kind of connection with main tunnel connecting position
Network combination of channels formula steel pipe sheet and construction method, to improve construction efficiency, ensure construction quality.
The present invention adopts the following technical scheme that to solve technical problem：
The design feature of service channel combined steel section of jurisdiction of the invention with main tunnel connecting position：For with main tunnel
Service channel at connecting position uses combined steel section of jurisdiction, and the combined steel section of jurisdiction refers to every steel pipe sheet by respective institute
Radian split in the main tunnel of circumferential location is arranged to two parts, and a part is to be located at fixing pipe fragment in service channel,
Another part is the interim section of jurisdiction section for needing to remove；Implemented between the fixing pipe fragment and interim section of jurisdiction section using straight bolt
Dismounting.
The design feature of service channel combined steel section of jurisdiction of the invention with main tunnel connecting position is lain also in：By described in
Seam in every steel pipe sheet between fixing pipe fragment and interim section of jurisdiction section is arranged to straightway so that by fixed in each steel pipe sheet
Complete cycle after section of jurisdiction section is assembled is connected the polygonized structure to be formed with each straightway.
The characteristics of construction method of service channel combined steel section of jurisdiction of the invention with main tunnel connecting position is：Construction
During, it is fixedly connected first between the fixing pipe fragment and interim section of jurisdiction section using straight bolt, makes its entirety be in
It is now conventional cylindrical section steel pipe sheet, assembly is carried out using usual manner for cylindrical section steel pipe sheet, when tunneling construction is completed, hole
Door interface implements closure and joint weld by construction requirement, completes entrance construction；Then, chain block is hung in tunnel top,
Interim section of jurisdiction section is tensed using chain block, the straight bolt in corresponding interim section of jurisdiction section is removed, completes the dismounting of combination section of jurisdiction,
Ensure that service channel section of jurisdiction does not invade shield tunnel gauge.
Compared with the prior art, the present invention has the beneficial effect that：
1st, the present invention uses combined steel section of jurisdiction, implements to tear open using straight bolt between fixing pipe fragment and interim section of jurisdiction section
Dress, it is no longer necessary to cut off at the scene, drastically increase site operation efficiency, be also greatly beneficial to ensure engineering matter
Amount.
2nd, the present invention is for every steel pipe sheet, using straightway approximation circular arc, largely facilitates the processing system of steel pipe sheet
Make.

Embodiment
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 main 21 connecting position of tunnel
Refer to every steel pipe sheet being arranged to two parts by the radian split in the main tunnel of respective place circumferential location, a part is position
The fixing pipe fragment 23 in service channel, another part are the interim section of jurisdiction sections 24 for needing to remove；In fixing pipe fragment 23 with facing
When section of jurisdiction section 24 between using straight bolt implement dismounting.
In specific implementation, the seam between fixing pipe fragment 23 in every steel pipe sheet and interim section of jurisdiction section 24 is pressed into two-end-point
Position is arranged to straightway so that by the complete cycle after 23 assembly of fixing pipe fragment 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 than circular arc point
