Description
Technical field
This utility model relates to shield tunnel, falls block leakage muscle particularly to a kind of tunneling shield segment damage and repairs structure.
Background technology
Shield Tunneling, when section of jurisdiction transport, lifting or shield attitude are abnormal, all may cause section of jurisdiction to go out
Block is fallen in existing breakage, occurs leakage muscle phenomenon under serious conditions.Section of jurisdiction occurs that block leakage muscle is fallen in breakage, can give shield duct piece structure durability
Impacting, repairing treatment is not in place simultaneously brings potential safety hazard to operation.
Occurring that to section of jurisdiction the process of block leakage muscle is fallen in breakage, conventional processing method is first breakage to be fallen block leakage muscle position float
Slurry is removed, and carries out dust cleaning, moistens with water, then uses the polymer slurries of mixing to carry out smearing slurry and repairs, finally supports
Protect.Owing to, during operation, dynamic load is relatively big, runs process for a long time, easily occurs again to fall block phenomenon, to train operation safety
Cause dangerous, and the useful life longevity of section of jurisdiction is caused certain impact.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of tunneling shield segment damage and falls the benefit knot of block leakage muscle
Structure, falls block position repairing in time shield duct piece breakage, is effectively improved the useful life of section of jurisdiction, it is ensured that operation safety in period and
The durability that section of jurisdiction uses.
The technical scheme that the above-mentioned technical problem of this utility model solution is taked is as follows:
Tunneling shield segment damage of the present utility model falls block leakage muscle and repairs structure, it is characterized in that it includes: fixing component,
In shield duct piece breakage leakage muscle position, interval is arranged, and its underpart vertically penetrates this connection internal and fixed thereto of shield duct piece；
Metal mesh sheet, fixes with each fixing component in breakage leakage muscle position and is connected；Patching material packed layer, layering filling is fixed on brokenly
Damage in leakage muscle position, until shield duct piece face, between orlop material packed layer with damaged leakage muscle position inner surface and adjacent two
Bonding interface agent is coated between material packed layer.
The beneficial effects of the utility model are, use the process mould of " (crab-bolt) bar planting+linked network+Polymer-Modified Mortar "
Formula, does not affect construction speed, safe operation process, efficiently, simple, put into personnel few, difficult drop-off after repairing, service life is relatively
Long, on section of jurisdiction durability substantially without impact, meet operation functional requirements, it is ensured that operation security.
This utility model can also be used for segment damage and falls block without leaking the repairing at muscle position.
Accompanying drawing explanation
This specification includes following two width accompanying drawings:
Fig. 1 is the plane graph that this utility model tunneling shield segment damage falls the repairing structure of block leakage muscle；
Fig. 2 is the elevation that this utility model tunneling shield segment damage falls the repairing structure of block leakage muscle.
Component name shown in figure and corresponding labelling: shield duct piece 1, damaged leakage muscle position 2, fixing component 3, metal
Mesh sheet 4, pipe sheet assembling seam 5, thin elastic plate material 6, patching material packed layer 7.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
Seeing figures.1.and.2, tunneling shield segment damage of the present utility model falls block leakage muscle repairing structure and includes: fixing structure
Part 3, in shield duct piece 1 damaged leakage muscle position 2, interval is arranged, and it is internal and solid therewith that its underpart vertically penetrates shield duct piece 1
Fixed connection；Metal mesh sheet 4, fixes with each fixing component 3 in breakage leakage muscle position 2 and is connected；Patching material packed layer 7, layering
Filling is fixed in damaged leakage muscle position 2, until shield duct piece 1 surface, orlop material packed layer 7 and damaged leakage muscle position 2
Bonding interface agent is coated between inner surface and between adjacent two material packed layers 7.Material packed layer 7 generally can use polymer to change
Property mortar, described metal mesh sheet 4 is adopted as reinforced mesh or steel fabric sheet.
This utility model use " (crab-bolt) bar planting+linked network+Polymer-Modified Mortar " tupe, do not affect construct into
Degree, safe operation process, efficiently, simple, put into personnel few, difficult drop-off after repairing, service life is longer, to section of jurisdiction durability
Substantially without impact, operation functional requirements is met, it is ensured that operation security.
The thickness of described patching material packed layer 7 should be less than 20mm, smears bonding interface agent between layers, before smearing
Need to keep being dried of interface with Hairdryer.
Seeing figures.1.and.2, tunneling shield segment damage of the present utility model falls the benefit structure of block leakage muscle, as follows
The reparation at block position is fallen for tunneling shield segment damage:
1, damaged leakage muscle position 2 (including hollowing part or rift portion) of shield duct piece 1 is thoroughly dug out；
2, rinse well with pressure clean water, and be sufficiently humidified so as to repair position, be allowed to be in the dry saturation state of saturation plane；
3, in breakage leakage muscle position 2, fixing component 3 is installed；
4, after breakage leakage muscle position 2 inner surface is anhydrous, bonding interface agent is coated；
5, in breakage leakage muscle position 2, metal mesh sheet 4 is fixedly mounted on fixing component 3；
6, insertion thin elastic plate material 6 at 5 is stitched at pipe sheet assembling；
7, by premixing through the satisfactory patching material of trial, it is layered repeatedly dense packing effect breakage leakage muscle position 2 until shield
Surface, structure section of jurisdiction 1, forms multilayer repair material packed layer 7 in breakage leakage muscle position 2；
8, moisture-keeping maintaining or cover film maintenance；
9, after material packed layer 7 to be repaired is stiff, extract out thin elastic plate material 6, with polisher flattened surface and polishing corner angle,
It is allowed to smooth out with other positions of shield duct piece 1.
The above this utility model tunneling shield segment damage that simply explains through diagrams falls block leakage muscle and repairs structure
Some principles, are not intended to be confined to by this utility model in shown and described concrete structure and the scope of application, therefore every institute
The corresponding amendment being likely utilized and equivalent, belong to the apllied the scope of the claims of this utility model.
