Abstract
The utility model relates to a double layer circular tunnel with deformation control device belonging to the field of tunnel. The tunnel is made up of pipe pieces by through seam assembling and is disposed of pull bars on suitable positions to control the deformation of tunnel. The tunnel has small structural inner force since applying the pipe piece assembling structure, reduces cost and controls the tunnel deformation effectively.
Description
Technical field
The utility model relates to tunnel-like, relates to a kind of double-layer structure circular tunnel with controlled deformation device concretely.
Background technology
(D＞10m) normally improves the integral rigidity in tunnel, controlled deformation by the staggered joint erection section of jurisdiction at common major diameter circular tunnel.Generally speaking, under the equal conditions operating mode, the tunnel structure distortion of through seam assembling section of jurisdiction is greater than the staggered joint erection section of jurisdiction, though and the tunnel malformation of adopting staggered joint erection to construct is less, but because the characteristics of its staggered joint erection, adjacent ring produces the internal force transmission because of compatibility of deformation, cause structural internal force to increase, the section of jurisdiction steel content generally will exceed the section of jurisdiction 25%～35% of through seam assembling of the same type, and for double-deck circular tunnel, normally by arranging the supporting construction of bracket structure as the upper deck guidance tape, because the staggered joint erection of section of jurisdiction, the position, section of jurisdiction is uncertain, need dispose many cover punching blocks for increasing bracket structure, the construction of section of jurisdiction and design difficulty strengthen, and increase construction costs greatly.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of double-layer structure circular tunnel with controlled deformation device is provided, the through seam assembling that the pipe sheet assembling in this tunnel adopts, and pull bar control tunnel deformation is set by appropriate location in the tunnel.
The utility model purpose realizes being finished by following technical scheme:
A kind of double-layer structure circular tunnel with controlled deformation device, comprise double-layer structure circular tunnel, be provided with upper deck guidance tape and flyunder plate in the tunnel, what it is characterized in that the pipe sheet assembling of described circular tunnel adopts is through seam assembling, and is provided with pull bar in circular tunnel.
Draw rod positions can be set in place near upper deck guidance tape place circular tunnel diameter.
The upper deck guidance tape can be precast construction, its with tunnel duct piece between be connected the welding that is by section of jurisdiction and lane plate reserved steel bar and after water to handle and realize.
The flyunder plate also can be prefabricated units.
Pull bar can be installed in as upper/lower positions: the upper deck guidance tape is supported by supporting base, and supporting base and section of jurisdiction are structure as a whole, and on the supporting base surface steel box is set, and reserving hole is installed pull bar on the steel box, and passes through nut screwing clamping in the steel box.Also can be installed in as upper/lower positions: both sides embedded nut or reinforcing bar connector, are middlely tightened with the connection of double end screwed pipe at the both sides correspondence position pull bar of plugging into as connector in the circular tunnel section of jurisdiction.
The utility model has the advantages that, tunnel duct piece adopts through seam assembling, structural internal force is little, the steel content of section of jurisdiction is little, and cost is low, and by in the appropriate location, tunnel pull bar being set, controlled tunnel deformation effectively, as calculated, under the equal conditions situation, the tunnel deformation that adds pull bar is generally less than the staggered joint erection tunnel.
Summary of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is embodiment 1 structural representation;
Accompanying drawing 3 is embodiment 2 structural representations;
Concrete technical scheme
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Figure 1-3, label 1-13 represents respectively: tunnel duct piece 1, upper deck guidance tape 2, flyunder plate 3, bracket structure 4, pull bar 5, steel box 6, reserving hole 7, nut 8, nut 9, hand hole 10, double end screwed pipe 11, concrete second pouring section 12, fill out husky 13.
Embodiment 1: the double-layer structure circular tunnel with controlled deformation device that present embodiment relates to, be provided with upper deck guidance tape 2 and flyunder plate 3 in the tunnel, what tunnel duct piece 1 assembly unit was wherein adopted is through seam assembling, and, be provided with pull bar 5 being positioned at circular tunnel diameter vicinity, upper deck guidance tape 2 place.
Upper deck guidance tape 2 is a precast construction, its with tunnel duct piece 1 between be connected by section of jurisdiction 1 and the welding of lane plate 2 reserved steel bars and after water to handle and realize.
Flyunder plate 3 is the prefabricated units that are shaped as " ∏ " type.
Embodiment 2: the difference of present embodiment and the foregoing description only is the installation site of pull bar 5, pull bar when mounted, both sides embedded nut 9 or reinforcing bar connector be as connector in circular tunnel section of jurisdiction 1, at the two routine correspondence positions pull bar 5 of plugging into, middlely tightens with the connection of double end screwed pipe.
As previously mentioned, the position of pull bar 5 is positioned near upper deck guidance tape 2 place's circular tunnel diameters, more helps the control structure distortion.Obviously pull bar 5 positions determine can suit measures to local conditions, flexible arrangement, as long as can satisfy structural calculation, vehicle, equipment current, gauge is installed.
Owing to use pull bar to make the section of jurisdiction through seam assembling become possibility, therefore can be easily in the tunnel section of jurisdiction of two waists arrange the supporting construction of bracket structure as the upper deck guidance tape, in the double-deck tunnel of prior art is the staggered joint erection tunnel, the position, section of jurisdiction is uncertain, need increase the punching block tricks for increasing bracket structure, and present embodiment adopts the through seam assembling form to need punching block quantity few, convenient construction and section of jurisdiction design, for example at present embodiment if adopt prior art, its double-deck tunnel is the staggered joint erection tunnel, the position, section of jurisdiction is uncertain, need dispose about 6 cover punching blocks for increasing bracket structure, and present embodiment adopts the through seam assembling form only to need 2 cover punching blocks.Certainly punching block quantity has difference at the tricks that different engineerings may need.
For ease of 2 rapid constructions of upper deck guidance tape, upper deck guidance tape 2 is designed to precast construction, construction stage is the freely supported structure that is held on the bracket structure, operational phase is according to the span situation, for reducing mid span moment, can water processing after the welding also by section of jurisdiction and lane plate reserved steel bar, make lane plate and circular tunnel structure form rigid joint, reduce span centre internal force, save construction investment.
For ease of the rapid construction of upper deck guidance tape, flyunder plate 3 also is designed to prefabricated units, and according to the principle of saving engineering quantity to greatest extent, this precast construction part is " ∏ " type, and the space back-up sand is handled under the road slab structure of both sides.
