Abstract
The new supporting structure of duct pieces of shield tunnel opening, it is related to shield tunnel technical field；It includes shear connector, section of jurisdiction opening, water expandable waterstop, steel reinforcement cage；It is equipped with the shear connector mutually suited at the segment joint of the section of jurisdiction open circumferential, and drills at segment joint, installation water expandable waterstop and steel reinforcement cage in hole.What the utility model generated has the beneficial effect that：Additional shape steel bracket supporting need not be used, section of jurisdiction can be directly abolished；It is transported in hole when suspension device does not influence to influence constructing tunnel；Suspension device construction technology is simple, and construction investment is few.
Description
Technical field
The utility model is related to shield tunnel technical fields, and in particular to the New Supporting knot of duct pieces of shield tunnel opening
Structure.
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.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of simple in structure, design conjunction is provided
The new supporting structure of reason, duct pieces of shield tunnel easy to use opening.
To achieve the above object, the technical solution adopted in the utility model is：It includes shear connector, section of jurisdiction opening, meets water
Expansion sealing strip, steel reinforcement cage；The shear connector mutually suited is equipped at the segment joint of the section of jurisdiction open circumferential, and section of jurisdiction connects
It drills at seam, installation water expandable waterstop and steel reinforcement cage in hole.
Preferably, pouring slightly expanded concrete in the hole.
The operation principle of the utility model is：By drilling at the segment joint of duct pieces of shield tunnel open circumferential,
Water expandable waterstop is installed, the shear connector of pouring reinforcement concrete structure forms rigid connect between segment joint in drilling
It connects, section of jurisdiction opening is born by shear connector and abolishes the shearing generated behind section of jurisdiction, the internal force in open loop is transferred to adjacent ring
On, to ensure the stability of pipe-plate lining, additional supporting need not be used, in hole when not influencing constructing tunnel transport and
Ensure structure safety.
With the above structure, what the utility model 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.

Fig. 2 is the local drawing that the utility model is mounted in shield tunnel；
Fig. 3 is the usage state diagram that the utility model is mounted in shield tunnel.
Reference sign：
Shear connector 1, section of jurisdiction opening 2, water expandable waterstop 3, steel reinforcement cage 4.
Specific implementation mode
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings.
Referring to such as Fig. 1 --- shown in Fig. 3, present embodiment adopts the following technical scheme that：It includes shear connector 1, pipe
Piece opening 2, water expandable waterstop 3, steel reinforcement cage 4；The section of jurisdiction, which is open to be equipped at the segment joint on 2 peripheries, mutually to be suited
Shear connector 1, and drill at segment joint, installation water expandable waterstop 3 and steel reinforcement cage 4 in hole.
Preferably, pouring slightly expanded concrete in the hole.
The construction method of present embodiment 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.
With the above structure, 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 advantages of basic principles and main features and the utility model of the utility model have been shown and described above.This
The technical staff of industry is retouched in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
That states only illustrates the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model
It will also have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.This practicality is new
Type is claimed range and is defined by the appending claims and its equivalent thereof.
