Description
Technical field
The utility model belongs to construction of tunnel technical field, is specifically related to a kind of tunnel lining concrete grouting device.
Background technology
Concrete lining trolley is the nonstandard product that in constructing tunnel process, secondary lining is indispensable, mainly contains simple and easy lining trolley, all-hydraulic automatic walking lining trolley and netted lining trolley.
Tunnel lining is divided into (1), and monolithic mould builds concrete-liner; (2) precast lining; (3) shotcrete lining cutting; (4) composite lining; (5) open cut tunnel lining cutting.
Full-hydraulic lining trolley can be divided into again side and roof arch formula, whole-circle needle beam type, bed die needle beam type, wholecircle traveling type etc.Also generally use in Hydraulic Tunnel and bridge construction and promote sliding formwork, jacking sliding formwork and turn over mould etc.Whole-round lining trolley is usually used in Hydraulic Tunnel construction, does not allow tunnel to have concrete construction longitudinal seam, generally uses wholecircle traveling type when Hydraulic Tunnel span is larger; The application of side and roof arch formula lining trolley is the most general, is usually used in the concrete Second Lining Construction of highway, railway tunnel and underground chamber.
1. simple and easy lining trolley
Simple and easy lining trolley is generally designed to steel arch posture, and use standard combination steel form, can not establish automatic walking, adopt outer power to drag, de-shuttering is all manual operation, and labour intensity is large.Such lining trolley is generally used for short tunnel construction, and particularly change frequent, that technological requirement is strict tunnel concrete lining construction for plane and spatial geometric shape complexity, operation, its superiority is more obvious.As wide (state) favour (state) speedway little Jin mouth double-arched tunnel, long 200m, plane is in the circular curve change section of R=300m, in hole, horizontal wall inscription changes to+5% from i=± 2%, this tunnel is also on the vertical curve of R=3000m simultaneously, make Tunnel shape in " hyperbolic " state, and middle wall is stalk design, outlet 15m is faded to the horn structure of R=7.5m by R=5.5m, tunnel steel bar concrete two serves as a contrast and adopts the design of plain type bow member chassis, solve these problems well, engineering cost is lower simultaneously.During simple and easy chassis uses, major part adopts artificial concrete, and the simple and easy lining trolley of little Jin mouth adopts the perfusion of concrete transfer pump car, and therefore the rigidity of chassis should be strengthened especially.The simple and easy lining trolley had also adopts Overall Steel Formwork, but de-formwork erection still adopts screw mandrel very heavy, and without automatically walking, such chassis generally adopts concrete transfer pump car to pour into.Simple and easy lining trolley generally adopts combined steel formwork, and combined steel formwork is generally thin plate and makes, and should consider the rigidity of steel form in the design process, so the Pin spacing of steel arch-shelf is unsuitable excessive.If steel form length is 1.5m, then the Pin spacing of steel arch-shelf on average should be not more than 0.75m, and the landing edge of steel form should be located between Pin and Pin, so that installation form fastener and template hook.If use delivery pump perfusion, then rate of flooding is unsuitable too fast, otherwise combined steel formwork will be caused to be out of shape, and especially more should slow down rate of flooding when lining thickness is greater than more than 500mm.Should be doubly cautious when binding perfusion, noting the perfusion situation of concrete at any time, pour into concrete by force after preventing from filling, otherwise burst-mode or chassis deformed damaged will be caused.
2. all-hydraulic automatic walking lining trolley
Be mainly used in medium tunnel construction, higher to construction speed, concrete surface quality requirements.This type of design of tunnel lining trolley is Overall Steel Formwork, hydraulic jack takes off formwork erection, and by the very heavy support of screw mandrel in construction, electric reducer is walked automatically or oil cylinder step-by-step movement is walked automatically, all adopts the perfusion of concrete transfer pump car.Major part lining trolley is such chassis.When designing such lining trolley, when meeting by Clearance requirement, installation site, bearing diagonal bottom inside door frame should be considered, as far as possible near column bottom, make it stressed best.Door frame crossbeam should be enough high, and conventional railway tunnel is not less than 400mm, and highway tunnel is not less than 5500mm.Adjustment minimum range between template end face and door frame is not less than 250mm, otherwise lining cutting section in front and back will be caused to overlap difficulty.
With noticing during such lining trolley that the laying discrepancy in elevation of both sides rail is not more than 1%, otherwise the distortion of screw mandrel very heavy and jacking cylinder will be caused.When the tunnel inside lining having ramp, in order to adjust lining cutting absolute altitude, the discrepancy in elevation of chassis front and back end, template end face and door frame end face can be caused not parallel, very large horizontal component is formed between template and door frame by making, cause the very heavy dislocation of the support screw between template and door frame, cause very heavy, oil cylinder damage.Therefore, when designing, should take into full account that the front and back discrepancy in elevation causes restraining structure or the adjustment System of horizontal component.Rail meter must be installed when locating formwork erection, screw that basic screw mandrel is very heavy, ground, door frame top is very heavy and ground, template top is very heavy, other measure also can be adopted if necessary to reinforce counterdie arch springing position, make door frame stressed little as far as possible, prevent from running mould and door frame distortion.
3. netted lining trolley
Netted lining trolley has structurally been compared to larger change mutually with traditional lining trolley.Tradition lining trolley chassis door frame in construction is stressed member, the lateral pressure that it is subject to is comparatively large, and the rigidity size with door frame produces and do not wait distortion, and should not on-line operation in the tunnel having larger horizontal wall inscription and longitudinal gradient, higher to operating environment requirements, otherwise chassis bulk deformation and damage will be caused.And netted lining trolley door frame in construction for not stressing part, the support member of its template is that ground, the top screw mandrel of limit mould arch springing is very heavy, door frame is only just stressed in de-formwork erection, walking process, and suffered power vertically downward, there is no lateral pressure, only would not need be out of shape by the rigidity that chassis deadweight design door frame is enough.In the tunnel having ramp when construction or walking, no matter be horizontal wall inscription or longitudinal gradient, height can be carried out by the jacking cylinder of door frame bottom and regulate, make chassis entirety be in level, go all out and roll force before chassis global non-existence, ensure that the overall stationarity of chassis.The screw mandrel having fully phased out support because of chassis is very heavy, and chassis location is simple, can adjust to lining cutting geometric position very fast, save a large amount of manpower and materials, improve work efficiency, shorten dust cycle, correspondingly saved engineering cost.
For ensureing the Rigidity and strength of crown template, top gantry designs becomes netted member structure, makes it stressed best, and template can not be out of shape displacement in lining cutting process.In whole chassis, the weakest link is lower bolster and counterdie knighthead, therefore the stressed size of counterdie fully should be calculated when designing lower bolster, widen arc plate width and thickness as far as possible, knighthead must pass through Calculation on Stability of Compressed Bar, ensure that brace has enough Rigidity and strengths, be unlikely in use to deform bending, cause running mould.The lining thickness of concrete, the slump, rate of flooding, aggregate size should be taken into full account and be whether the impact of the factors such as steel bar concrete in computational process.Ground, counterdie arch springing top screw mandrel is very heavy is main stressed member, when whole template is below the center line of the lining cutting center of circle, supporting by it completely, therefore should consider its form of structure and rigidity size when designing.In use, this is very heavy must firmly hold out against in ground, and do not allowed loosening phenomenon, if necessary, other part available is reinforced, and as supplemental support, prevents from running mould and chassis is shifted downwards.It should be noted, very heavyly must to tighten as the rail meter of chassis longitudinal register and basic screw mandrel, to block jail and push up firm rail, particularly more should note during lining cutting on ramp.Such lining trolley is mainly used in longspan tunnel and Cavity Construction.If adopt traditional type full-hydraulic lining trolley, then gantry design is difficult to meet instructions for use, causes door frame deformed damaged, is first door frame crossbeam torsional deformation, finally causes running mould.If increase crossbeam, strengthen vertical to lean on, lower longeron, end face bearing diagonal cross section, then cause unnecessary waste, and adopt netted lining trolley can overcome above difficulty.Because such lining trolley is large span construction, should consider its operability during design, its working stand and gangway should be able to conveniently arrive each operating position.
