Detailed description of the invention
Below in conjunction with specific embodiment, the detachable deformation joint structure for tunnel in cold area described in the utility model is described further, but protection domain of the present utility model is not limited to this.
Embodiment 1
For a detachable deformation joint structure for tunnel in cold area, described detachable deformation joint structure is from comprising country rock 1, sprayed mortar 2, non-woven fabrics 3, splash guard 4, insulation layer 5, steel sheet 6 and secondary lining 8 from top to bottom; Deformation joint is carved with in described secondary lining 8; Described deformation joint is suitable for reading is provided with porous spring semicanal 7, and middle part is provided with rock-wool heat insulation plate 10, and end opening is provided with wave shaped steel plate 11; Described wave shaped steel plate 11 is fixed by the crab-bolt 9 of deformation joint both sides; The width of described deformation joint is 8cm; The thickness of described steel sheet 6 is 0.7mm; Described crab-bolt 9 is with a nut 31.
During enforcement, first construct on the left of deformation joint, in the early stage after supporting, inwardly non-woven fabrics 3, splash guard 4 successively, insulation layer 5, use spacer bars 21, template 21 and blocking plate 23 that steel sheet 6, porous spring semicanal 7 are fixed on relevant position with rock-wool heat insulation plate 10 combining structure, concreting in blocking plate 23 with template 22 and preliminary bracing Special composition; Then construct on the right side of deformation joint, lay non-woven fabrics 3 successively, welding splash guard 4, lay insulation layer, concreting in porous spring semicanal 7 with rock-wool heat insulation plate 10 combining structure and template 22 space, when concrete strength reaches requirement, then crab-bolt 9 of constructing, erection wave shaped steel plate 11 is also fixed in crab-bolt with nut.After deformation joint structure, in highway operation, frost heave occurs, deformation joint is destroyed by the gutter of country rock side, and lining cutting in summer behind water can be flowed out along deformation joint, affects traffic safety; During maintenance, deformation joint structure outboard nut 31 and wave shaped steel plate 11 can be unloaded, clean out the destruction residue of porous spring semicanal 7 and rock-wool heat insulation plate 10 in deformation joint, embed new porous spring semicanal 7 and rock-wool heat insulation plate 10 combining structure, wave shaped steel plate 11 is fixed in crab-bolt 9.
Compared with prior art, the detachable deformation joint structure building block standardization for tunnel in cold area described in the utility model, detachably, tunnel late maintaining is convenient; Adopt rock-wool heat insulation plate as packing material, there is fire prevention and heat insulation effect; Outer wave shaped steel plate rigidity is large, and can resist frost heave load in deformation joint in winter, prevent packing material from extruding, its ripple also has drainage, can by summer deformation joint a small amount of infiltration be discharged to both sides, tunnel and enter gutter.
