Description
Technical field
The utility model relates to shield structure applied technical field, especially a kind of shield lining seam construction.
Background technology
In order to effect a radical cure the city common faults such as overstaffed congested in traffic environment pollution, many cities just at design and construction underground railway, cross-river tunnel, underground water pipeline, communication, electricity cable, heat supply, gas flue and other Deep underground space exploitation engineering.In urban tunnel construction, the application of shield construction method is comparatively extensive.Compared with cut and cover method, pipe jacking method, immersed tunnelling method, Mining Method, shield method tunnel construction has, the unique advantage such as environmental impact contamination light little to life of urban resident interference.Up to now, shield construction has the history of more than 100 year, and in mutually more unexpectedly striving with the various tunneling method be not mutually exclusive, shield construction is very important a kind of mode, but there is the bad and weak problem of impermeability of corrosion resistance in some shield technique now.
Prior art can not meet the needs of people, and for making up prior art deficiency, the utility model aims to provide one can improve corrosion resistance, the shield lining seam construction structure that impermeability is strong.
For achieving the above object, the utility model is by the following technical solutions: a kind of shield lining seam construction, at least comprises stripper plate, semilune jack, excavation face jack, weight lifting arm jack, shield machine seal, shield structure jack, front eaves jack, radial hobboing cutter, slip jack, underplate concrete, track, template, secondary lining and once lining; Described stripper plate is arranged on shield structure left upper end; Shield structure upper end is provided with semilune jack, shield structure middle part is provided with excavation face jack; Described weight lifting arm jack is arranged on shield structure upper right side, and the right-hand member of shield structure is provided with shield machine seal; Described radial hobboing cutter to be arranged on below excavation face jack and with shield structure soffit compact siro spinning technology; Described shield structure jack is arranged on the upper right side of front eaves jack; Secondary lining is provided with and compact siro spinning technology at ring-type once lining inner surface; Secondary lining inner surface is provided with template, and template and intersection, secondary lining lower end are provided with track.
As optimisation technique scheme of the present utility model: described secondary lining formwork erection waters the concrete of the left and right two waist sidewall smashing 240 °; Paste flexible polyurethane foam at the back side, section of jurisdiction, then inject water glass or cement swell soil by the injected hole after the ring of section of jurisdiction; Be coated with last layer bituminous epoxy paint or brushing chlorosulfonated polyethylene outside described section of jurisdiction and add silica flour in concrete.
Compared with prior art, the beneficial effects of the utility model are: this structure has better globality and water proofing property, it can save a large amount of vertical, circumferential weld waterproofing materials and connecting bolt, speed of application is faster than pipe sheet assembling lining cutting, and can continuous mechanized operation, this slip steel form extruded concrete inner surface of tunnel is bright and clean, uses the comparable prefbricated tunnel lining of cast-in-situ concrete to reduce cost.Concrete remains homeostasis pressure before not solidifying, be close to stratum, thus play supporting role timely, stratum is difficult to produce loose and sink, pass through Lyons, France subway line one section in the running tunnel in Rhone and Sohne two rivers, adopt extruded concrete lining structure construction land subsidence close to zero.Suffered strata pressure is quite even, and thus in structure, axle power increases and moment of flexure minimizing, and to structure stress advantageously, the strong impermeability of resistance to corrosion of this structure is strong, and seam is closely connected, practical, is easy to promote the use of.
