Description
Technical field
The utility model belongs to shield duct piece technical field, more particularly to a kind of repairing and reinforcement structure of shield duct piece.
Background technology
At present, method for tunnel construction has cut and cover method, subsurface excavation method etc., wherein, the shield method in subsurface excavation method is a kind of full machinery
Change construction method, because shield method has the advantages that to excavate facility that is safe, not influenceing ground, be widely used in tunnel and build
If such as：Railway tunnel, vcehicular tunnel, subaqueous tunnel, underground railway etc., following is a brief introduction of the structure of shield machine and
The process of shield-tunneling construction：Shield machine includes main frame and rear three supporting vehicle frames, and the front end of main frame is cutterhead, is installed on cutterhead
There is different cutters, motor drives the rotation of cutterhead, and some groups of hydraulic jacks promote cutterhead to advance, so as to realize to soil layer
Chip, by pipeline by the dregs transportation after chip to tunnel outer, after cutterhead pushes ahead a certain distance, hydraulic jack
Top bounces back to the direction of cutterhead temporarily, and duct piece assembling machine slings shield segment assembling to the hydraulic jack to have bounced back with having installed
Between good shield duct piece, then the rear end of hydraulic jack and the front end of shield duct piece compress, and last several pipe sheet assemblings are
Annulus, assembled rear jack top elongation is completed, continues to push ahead cutterhead.
Shield duct piece is typically manufactured using armored concrete, and intensity is higher, but toughness is poor, by some vibrations or punching
When hitting, buffer capacity is limited, if regular is given a shock, is such as arranged in subway tunnel, it will cause shield duct piece
The appearance for the problems such as sealing or bulk strength progressively decline, or even the blocking breakage in section of jurisdiction can be caused.When shield duct piece occurs
After breakage, if changed to section of jurisdiction, difficulty it is larger, it is necessary to equipment it is more, if directly repaired to section of jurisdiction, mesh
It is preceding also to be realized without preferable technological means.
Therefore, the repairing and reinforcement structure for inventing a kind of shield duct piece seems very necessary.
The content of the invention
The utility model in order to solve shield duct piece occur it is damaged after, to section of jurisdiction change that difficulty is big, cost is high asks
A kind of topic, there is provided the repairing and reinforcement structure of shield duct piece.
The utility model is achieved by the following technical solution：A kind of repairing and reinforcement structure of shield duct piece, including shield
Structure section of jurisdiction, the reinforcing position to be repaired of shield duct piece are provided with groove, and groove includes the transverse concave groove that square crossing sets and vertical
Groove, bottom portion of groove are provided with waterproof matrix, be provided with groove with its structure identical reinforced mesh, reinforced mesh include by
Tie up fixed silk and orthogonal transverse steel and longitudinal reinforcement, transverse steel are arranged in transverse concave groove, longitudinal reinforcement is set
In vertical groove, mounting hole is symmetrically provided with the shield duct piece on the outside of groove, concrete has been poured in groove, has been set on the outside of groove
Baffle plate is equipped with, baffle plate radian and shield duct piece radian identical, baffle plate are fixed on shield duct piece by screw and mounting hole.Gear
Plate be provided with section of jurisdiction identical radian, be advantageous to baffle plate and be preferably bonded with section of jurisdiction, avoid the concrete in groove come off and
The loosening of reinforced mesh, it ensure that the consolidation effect of shield duct piece.
The groove domestic demand casting concrete of repairing and reinforcement structure, the depth of groove determine the thickness of concrete, newly poured
Concrete is excessively thin easily to come off, blocked up waste of materials, increases cost.To ensure that groove inner concrete and being bonded for shield duct piece are steady
Gu preferably, the depth bounds of groove is 6-8 centimetres, and the concrete grade poured in groove is than shield duct piece concrete
The high grade of label.
Bed course is provided between baffle plate and shield duct piece, bed course is located at the external margin of groove, and is set around groove, bed course
Using paper -based asphalt felt.Paper -based asphalt felt can effectively prevent the stream of its internal moisture after concreting
Lose, ensure the pouring quality of concrete, improve the durability of shield duct piece repairing and reinforcement structure.
Waterproof matrix is to smear to form using cement-base infiltration crystallization.Cementitious capillary waterproofing material is that one kind contains
The powdery water-repellent paint of active compound, under the conditions of having existing for water, reactive compound permeates to inside concrete, in hole
A large amount of long chain crystallizations not soluble in water, plug capillary channel of filling in a form are formed in gap and crack, so that concrete is fine and close, waterproof,
It is applicable to the surfaces externally and internally of various concrete structures or the waterproof of body and the repairerment of permanent waterproof.
The utility model has the advantage that compared with prior art is with caused effect：
It is simple in construction, reasonable in design, by laying equal stress on needing the shield duct piece of repairing and reinforcement progress cover type to open up groove
Transverse concave groove and vertical groove combining structure new to apply reinforced concrete structure, that groove is set using square crossing, greatly
The stability for repairing structure is enhanced, cement-base infiltration crystallization is scribbled in groove, can fast and effectively play waterproof action, is repaired
The baffle plate being fixed with shield piece identical radian measure itself is reinforced on the outside of position, avoids lacking for impression quality difference after the completion of reinforcing
Fall into.
