Description
Technical field
The present invention relates to shield tunnel technical fields, and in particular to the new supporting structure of duct pieces of shield tunnel opening.
Background technology
Currently, being required for installation interim when the structure constructions such as accessory structure of shield tunnel such as service channel, waste water pump house
Shaped steel supporting construction after abolish assembled tunnel segment structure, then implement excavation construction in hole, to reduce section of jurisdiction opening construction
Interference to main tunnel piercing and ensure that the structure safety of section of jurisdiction opening and stabilization are in duct pieces of shield tunnel opening construction
Weight difficult point.General support pattern is typically to support section of jurisdiction using formed steel construction central shoring or portal frame, to ensure shield duct piece
Opening safety, but the pipelines such as the water and electricity supply of cleaning shield machine are needed before these measures construction, temporary track transport is interrupted, is influenced
The production scheduling that shield machine normally tunnels, or need after equal tunnel holing throughs can the construction period it is longer.It is managed in order to avoid reducing
Influence of the piece opening to shield tunnel construction, while ensuring section of jurisdiction hatch frame safety, shear connector supporting section of jurisdiction need to be used to be open
Support pattern.
Invention content
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of simple structure and reasonable design, make
The new supporting structure and its construction method being open with convenient duct pieces of shield tunnel.
To achieve the above object, the technical solution adopted by the present invention is：The new supporting structure of duct pieces of shield tunnel opening,
It includes shear connector, section of jurisdiction opening, water expandable waterstop, steel reinforcement cage；It is set at the segment joint of the section of jurisdiction open circumferential
There is the shear connector mutually suited, and drills at segment joint, installation water expandable waterstop and steel reinforcement cage in hole.
Preferably, pouring slightly expanded concrete in the hole.
The construction method of the new supporting structure of duct pieces of shield tunnel opening, it is comprised the following steps：
1, driving passes through tunnel duct piece open area, shield segment assembling；
2, drill at the segment joint of duct pieces of shield tunnel open circumferential, drill in installation water expandable waterstop, solid
Determine steel reinforcement cage, pours slightly expanded concrete；
3, section of jurisdiction is abolished, implements to excavate in hole.
The operation principle of the present invention is that：By drilling at the segment joint of duct pieces of shield tunnel open circumferential, drilling
Interior installation water expandable waterstop, the shear connector of pouring reinforcement concrete structure form rigid connection between segment joint, lead to
It crosses shear connector and bears section of jurisdiction opening and abolish the shearing generated behind section of jurisdiction, the internal force in open loop is transferred on adjacent ring, from
And ensure the stability of pipe-plate lining, additional supporting need not be used, transports and ensures in hole when not influencing constructing tunnel
Structure safety.
Using the above structure with after construction method, what the present invention generated has the beneficial effect that：
1, additional shape steel bracket supporting need not be used, section of jurisdiction can be directly abolished；
2, it is transported in hole when suspension device does not influence to influence constructing tunnel；
3, suspension device construction technology is simple, and construction investment is few.

Some embodiments of invention without having to pay creative labor, may be used also for those of ordinary skill in the art
With obtain other attached drawings according to these attached drawings.
Referring to such as Fig. 1 --- shown in Fig. 3, present embodiment adopts the following technical scheme that：Duct pieces of shield tunnel is open
New supporting structure, it include shear connector 1, section of jurisdiction opening 2, water expandable waterstop 3, steel reinforcement cage 4；The section of jurisdiction opening
It is equipped with the shear connector 1 mutually suited at the segment joint on 2 peripheries, and drills at segment joint, water-swellable sealing is installed in hole
Item 3 and steel reinforcement cage 4.
Preferably, pouring slightly expanded concrete in the hole.
The construction method of the new supporting structure of duct pieces of shield tunnel opening is as follows：
1, driving passes through tunnel duct piece open area, shield segment assembling；
2, drill at the segment joint of duct pieces of shield tunnel open circumferential, drill in installation water expandable waterstop, solid
Determine steel reinforcement cage, pours slightly expanded concrete；
3, section of jurisdiction is abolished, implements to excavate in hole.
Using the above structure with after construction method, what present embodiment generated has the beneficial effect that：
1, additional shape steel bracket supporting need not be used, section of jurisdiction can be directly abolished；
2, it is transported in hole when suspension device does not influence to influence constructing tunnel；
3, suspension device construction technology is simple, and construction investment is few.
The basic principles and main features and advantages of the present invention of the present invention have been shown and described above.The skill of the industry
Art personnel it should be appreciated that the present invention is not limited to the above embodiments, the above embodiments and description only describe
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these
