Background technique
Currently, domestic metro shield section service channel passes through predominantly layer of sand, soft stratum etc., city underground shield area
The main construction procedure of room machine method service channel is as follows:
(1) the compound section of jurisdiction of assembly Mechanical Method service channel portal at service channel shield running tunnel；
(2) steel loop is welded in service channel shield section portal position；
(3) in service channel shield running tunnel, draw into trolley, inner support system be unfolded, to service channel shield section into
The pre- top of row；
(4) in portal steel loop position, connection originates steel bushing, installs shield reaction frame；
(5) it is punched in running tunnel pipe of concrete on piece, detecting water by pilot hole is carried out to service channel；
(6) it is punched in running tunnel pipe of concrete on piece, grouting and reinforcing is carried out to the soil body outside service channel；
(7) in service channel position, service channel shield machine is originated, and cuts portal position concrete.
For the main compound section of jurisdiction in tunnel connection channel position of shield, due to being ejected by shield in service channel digging process
The load of cutting portal section of jurisdiction influences and subsequent portal abolishes entirety stress system in section of jurisdiction at rear service channel and drastic change occurs,
So that compound tunnel segment structure load variation is greatly and complicated, the density of load is high.These are to the main tunnel connection channel position of shield
More stringent requirements are proposed for tunnel segment structure.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind can effectively enhance duct piece connector intensity and with the company on periphery
The compound tunnel segment structure of Mechanical Method service channel portal fringing connect.
The technical scheme of the invention to solve the technical problem is: a kind of Mechanical Method service channel portal fringing is multiple
Tunnel segment structure is closed, is provided with encased steel plate on the extrados of the compound section of jurisdiction, the back side of the encased steel plate is provided with filling
Hole is starched, section of jurisdiction steel rib is welded in the inside of the encased steel plate, and the inner cavity of the compound section of jurisdiction has poured concrete liner, institute
Joint section section of jurisdiction intrados between the connector outer rim of the section of jurisdiction steel rib and the compound section of jurisdiction stated is provided with steel fringing, described
Steel fringing one end and the adjacent section of jurisdiction steel rib between pass through welded connection, the other end of the steel fringing
Pass through welded connection with the steel fringing of the adjacent compound section of jurisdiction.
Between the encased steel plate and the concrete liner, the steel fringing and the concrete liner it
Between and the section of jurisdiction steel rib and the concrete liner between be fastenedly connected respectively by WELDING STUDS.Guarantee coagulation
It is closely connected between native liner and section of jurisdiction steel construction, prevents from cracking.
Build-in has and answers for connecting portal position machinable concrete segment with described in length and breadth in the joint section section of jurisdiction
Close the glass fiber-reinforced polymer of section of jurisdiction.Guarantee the intensity that section of jurisdiction is cut at service channel portal.
The connector of the compound section of jurisdiction is using concave-convex tenon structure, the inside setting of the rebate section of the compound section of jurisdiction
There is cracking resistance reinforcing rib.
The inside and outside edge of the compound section of jurisdiction is respectively disposed with reinforced mesh.
It is attached between the adjacent compound section of jurisdiction by curved bolt, the adjacent steel fringing is in seam position
It sets and is welded to connect.
Compared with the prior art, the advantages of the present invention are as follows: a kind of Mechanical Method service channel portal fringing of the present invention is compound
Tunnel segment structure, the compound section of jurisdiction extrados steel plated, joint section section of jurisdiction intrados Baogang fringing, so that at compound duct piece connector
Outer each steel plated, can effectively enhance duct piece connector intensity and the connection with periphery；Duct piece connector structure section is by concrete simultaneously
It pours, greatly reduces the difficulty of processing of duct piece connector mold and the modification to front mold is worked as；After the completion of pipe sheet assembling,
Steel fringing position is welded on the inside of compound segment joint, it is possible to provide the better force-transfer characteristic of duct piece connector and globality.
In conclusion a kind of compound tunnel segment structure of Mechanical Method service channel portal fringing of the invention, leads to compared to common
It stitches fashioned iron and mixes tunnel segment structure, the compound tunnel segment structure of service channel portal fringing can carry out preferably stress for section of jurisdiction and transmit, simultaneously
Rebate end is using concrete structure combination steel fringing and reinforces cracking resistance muscle substitution clean steel connector, can guarantee section of jurisdiction stress performance
On the basis of, the highly difficult processing technology of section of jurisdiction clean steel connector is avoided, service channel portal section of jurisdiction economy is effectively increased.
