Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind to be based on I-shaped steel plate
Shield tunnel ruggedized construction and construction method.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of shield tunnel ruggedized construction based on I-shaped steel plate, which includes being bonded in in reinforcing area
I-shaped steel plate at shield duct piece intrados, the I-shaped steel plate unit that the I-shaped steel plate is arranged side by side by muti-piece are constituted, often
A I-shaped steel plate unit by the edge of a wing, top plate, web and bottom plate be integrally formed, adjacent I-shaped steel plate unit one-pass molding or
It is arranged around top plate by edge of a wing welding or connector connection molding, the edge of a wing, top plate, web and bottom plate are mutually perpendicular to
Setting constitutes closure square hole, and arranged direction is along tunnel circumferential direction.
Filling hole is preset on the bottom plate, is passed through filling hole in the closure square hole and is filled filler.
The edge of a wing is mutually bonded by binder with to the shield duct piece intrados in reinforcing area, and is opened thereon
If hole for the expansion bolt, the binder is no-solvent type modified epoxy class steel bonding potting compound or silica gel.
The filler is micro-expansion cement mortar or slightly expanded concrete.
The reinforcement form of the ruggedized construction includes rigidity reinforcement form and the tunneling borings such as connector local stiffening form, tunneling boring
Variation rigidity reinforcement form.
When section of jurisdiction ring integrality is without deformation, only when opening or cracking occur in local joint location, then connector office is selected
Portion's reinforcement form is arranged to the shield duct piece joint location in reinforcing area using monolithic or muti-piece I-shaped steel plate, and passed through
Expansion bolt on the edge of a wing is fixed.
When section of jurisdiction, there is overall deformation in ring, and the serious damages such as percolating water, leakage is husky, convergent deformation is larger occurs in section of jurisdiction ontology
When, then select reinforcement form for the rigidity reinforcement form such as tunneling boring, I-shaped steel plate is arranged along tunnel circumferential direction wholecircle, and passes through the edge of a wing
On expansion bolt be fixed.
When section of jurisdiction, there is overall deformation in ring, but damage concentrates at duct piece connector, when section of jurisdiction ring body is without obvious disease then
Select reinforcement form for tunneling boring variation rigidity reinforcement form, it is circumferentially disposed along tunnel using muti-piece I-shaped steel plate, adjacent two pieces
It is reinforced by way of steel bonding between I-shaped steel plate, to form tunnel circumferential direction wholecircle arrangement.
A kind of construction method of the shield tunnel ruggedized construction based on I-shaped steel plate, comprising the following steps:
Step 1: tunnel safety assessment is carried out according to the measurement result of shield tunnel deformation, specifically:
According to the cracking, faulting of slab ends, connector of duct pieces of shield tunnel opening, section of jurisdiction annular strain, seam percolating water and leakage silt
Situation carries out tunnel structure safety evaluation, obtains corresponding assessment section and belongs to local lesion or whole damage, is general
Slight damage or serious damage;
Step 2: according to safety evaluation as a result, selection shield tunnel Scheme of Strengthening, the Scheme of Strengthening include connector part
The rigidity such as Scheme of Strengthening, tunneling boring Scheme of Strengthening and tunneling boring variation rigidity Scheme of Strengthening, while determining and reinforcing rigidity;
Step 3: according to determining reinforcing rigidity, making I-shaped steel plate, and preset filling hole on I-shaped steel plate, by work shape
The web of steel plate is harmonious along tunnel circumferential direction spread, cambered surface and the duct pieces of shield tunnel intrados of I-shaped steel plate;
Step 4: the shield duct piece treated in reinforcing area is polished using angle grinder, is exposed fresh face and is removed surface
