Description

A kind of tunnel lining concrete grouting device
Technical field
The invention belongs to Tunnel Engineering technical field, and in particular to a kind of tunnel lining concrete grouting device.
Background technology
Concrete lining trolley is the nonstandard product that secondary lining is indispensable during constructing tunnel, mainly there is simple lining Platform building cart, all-hydraulic automatically walk lining trolley and netted lining trolley.
Tunnel-liner is divided into (1) monoblock type mould and builds concrete- liner;(2) precast lining;(3) shotcrete lining cutting;(4) combined type serves as a contrast Build;(5) open cut tunnel lining cutting
Full-hydraulic lining trolley can be divided into side and roof arch formula, whole-circle needle beam type, bed die needle beam type, wholecircle traveling type etc. again. Lifting sliding formwork, jacking sliding formwork and overmolded etc. are also generally used in Hydraulic Tunnel and bridge construction.Whole-round lining trolley is usually used in In Hydraulic Tunnel construction, do not allow tunnel to have concrete construction longitudinal seam, typically worn when Hydraulic Tunnel span is larger using wholecircle Line;Side and roof arch formula lining trolley application is the most universal, and the concrete secondary lining for being usually used in highway, railway tunnel and underground chamber is applied Work.
1. simple lining trolley
Simple lining trolley is typically designed as steel arch posture, using standard combination steel form, can not set automatically walk, uses Outer power dragging, takes off all manual operations of shuttering, labor intensity is big.Such lining trolley is generally used for short tunnel construction, Tunnel concrete lining construction frequent, that technological requirement is strict is changed especially for plane and spatial geometric shape complexity, process, its Superiority becomes apparent from.As wide (state) favour (state) highway little Jin mouth double-arched tunnels, long 200m, plane are in R=300m circle Curvilinear motion section, horizontal slope changes to+5% from i=± 2% in hole, while the tunnel is also on R=3000m vertical curve, makes Tunnel Shape is in " hyperbolic " state, and middle wall is stalk design, and outlet 15m is faded to R=7.5m horn structure, tunnel by R=5.5m The lining of reinforced concrete two is designed using plain type bow member chassis, solves these problems well, while engineering cost is relatively low.Simple platform Artificial concrete is largely used in car use, the simple lining trolley of little Jin mouths is irrigated using concrete transfer pump car, therefore chassis Rigidity should especially be strengthened.The simple lining trolley having also uses Overall Steel Formwork, but de- formwork erection is still very heavy using screw mandrel, without certainly Dynamic walking, such chassis are typically irrigated using concrete transfer pump car.Simple lining trolley generally uses combined steel formwork, combined steel Plate is generally thin plate making, is considered as the rigidity of steel form in the design process, so the Pin spacing of steel arch-shelf is unsuitable excessive.Such as Fruit steel form length is 1.5m, then the Pin spacing of steel arch-shelf should averagely be not more than 0.75m, and the landing edge of steel form should be located at Between Pin and Pin, in order to which installation form fastener and template are linked up with.If irrigated using delivery pump, rate of flooding should not mistake It hurry up, otherwise combined steel formwork will be caused to deform, especially should more slow down rate of flooding when lining thickness is more than more than 500mm. Binding should be doubly cautious when irrigating, and pay attention to the perfusion situation of concrete at any time, prevent from irrigating concrete after filling by force, otherwise will cause quick-fried mould Or chassis deformed damaged.
2. all-hydraulic automatically walk lining trolley
It is mainly used in medium tunnel construction, it is higher to construction speed, concrete surface quality requirements.Such design of tunnel lining trolley Formwork erection is taken off for Overall Steel Formwork, hydraulic jack, the very heavy support of screw mandrel, electric reducer automatically walk or oil cylinder stepping are leaned in construction Formula automatically walk, all irrigated using concrete transfer pump car.Most of lining trolley is such chassis.Design such lining trolley When, in the case where meeting to pass through Clearance requirement, bearing diagonal bottom installation site on the inside of door frame is considered as, as close to column Bottom, it is best to be allowed to stress.Door frame crossbeam is sufficiently high, and conventional railway tunnel is not less than 400mm, and vcehicular tunnel is not less than 5500mm.Adjustment minimum range between template end face and door frame is not less than 250mm, and front and rear lining cutting section overlap joint otherwise will be caused tired It is difficult.
It should be noted that the laying discrepancy in elevation of both sides rail is not more than 1% during with such lining trolley, screw mandrel otherwise will be caused very heavy Deformed with jacking cylinder.When there is the tunnel inside lining in ramp, in order to adjust lining cutting absolute altitude, the height of chassis front and back end can be caused Difference, template end face and door frame end face are not parallel, will make to form very big horizontal component between template and door frame, cause template and door The very heavy dislocation of support screw between frame, cause very heavy, oil cylinder damage.Therefore in design, it should take into full account that the front and rear discrepancy in elevation is made Into the restraining structure or adjustment system of horizontal component.Rail meter must be installed when positioning formwork erection, screw that basic screw mandrel is very heavy, door Frame top very heavy and template top it is very heavy, also other measures can be used to reinforce lower mould arch springing position if necessary, make door frame stress It is as small as possible, prevent from running mould and door frame deformation.
3. netted lining trolley
Netted lining trolley has made larger change in structure compared with traditional lining trolley.Traditional lining trolley is being applied Chassis door frame is stressed member in work, and the lateral pressure that it is received is larger, is produced with the rigidity size of door frame and does not wait deformation, and should not had Directly worked in the tunnel of larger horizontal slope and longitudinal slope, it is higher to operating environment requirements, it otherwise will cause chassis overall deformation and damage It is bad.And netted lining trolley door frame in construction not stress part, the support member of its template for side mould arch springing top ground screw mandrel Very heavy, the door frame only ability stress in de- formwork erection, walking process, and suffered power is vertically downward, only need to be by chassis without lateral pressure The enough rigidity of deadweight design door frame would not deform.In the tunnel for have ramp construct or walk when, whether horizontal slope or Longitudinal slope, height regulation can be carried out by the jacking cylinder of door frame bottom, make chassis overall generally in horizontality, chassis Gone all out before being not present and roll force, ensure that the overall stationarity of chassis.It is very heavy that the screw mandrel of support has been fully phased out because of chassis, Chassis positioning is simple, can be adjusted to lining cutting geometric position very fast, save substantial amounts of manpower and materials, improve work efficiency, contracts Short dust cycle, has correspondingly saved engineering cost.
To ensure the rigidity and intensity of crown template, for top gantry designs into netted member structure, it is best to be allowed to stress, Template will not deform displacement during lining cutting.Most weak link is lower template and lower mould knighthead in whole chassis, Therefore the stress size of mould, widens arc plate width and thickness, knighthead as far as possible under should fully being calculated when designing lower template It must ensure that brace has enough rigidity and intensity by Calculation on Stability of Compressed Bar, be unlikely to the bending that deforms in use, lead Cause to run mould.Should be taken into full account in calculating process the lining thickness of concrete, the slump, rate of flooding, aggregate size and whether be The influence of the factors such as reinforced concrete.Lower mould arch springing top screw mandrel it is very heavy be main stressed member, whole template lining cutting center of circle center line with When lower, supported completely by it, therefore its structure type and rigidity size are considered as in design.In use, this is very heavy necessary Firmly hold out against in ground, be not allow for loose phenomenon, if necessary, can be reinforced with other, as Auxiliary support, prevented Run mould and chassis shifts downwards.It should be noted that as the rail meter of chassis longitudinal register and basic screw mandrel it is very heavy must tighten, The firm rail in card jail and top, particularly more should be noted that in lining cutting on ramp.Such lining trolley be mainly used in longspan tunnel and Cavity Construction.If using traditional type full-hydraulic lining trolley, gantry design is difficult to meet requirement, causes door frame Deformed damaged, it is door frame crossbeam torsional deformation first, ultimately results in race mould.If increasing crossbeam, increase it is vertical lean on, lower longeron, end Face bearing diagonal section, then unnecessary waste is caused, and using netted lining trolley the above can be overcome difficult.Due to such lining Platform building cart is large span construction, is considered as its operability during design, and its working stand and gangway should be able to conveniently reach each Individual operating position.
