Description
Technical field
The present invention relates to a kind of tunnel double-lining concrete blinding trolley, specifically a kind of tunnel double-lining concrete construction is without door
Frame formwork jumbo belongs to road and bridge construction field.
Background technique
With the fast development that national basis is built, more strict requirements are proposed to construction quality and safety.
Especially the construction quality of Railway Tunnel concrete is required more to standardize, tunnel double-lining concreting generally uses 12
Rice formwork jumbo segmentation successively pours, and inevitably there are construction joints between every section, by every section of construction joint of job specfication requirement
It should be smooth smooth.And code requirement is extremely difficult in practice of construction, especially ground face upward 2 meters or so seam crossing most
It is easy to appear concrete height faulting of slab ends, and faulting of slab ends degree is larger, generally taken to eliminate faulting of slab ends in faulting of slab ends position erection construction
The concrete being higher by is polished flat on platform with sanding machine suitable by platform, construction personnel；There are also be exactly small abutment wall and lower arc template
Lower part lap-joint is also easy to appear faulting of slab ends, and main cause is that the bottom of formwork jumbo lower part camber template is added with screw rod and ground
Gu the angle of two fulcrums is generally acute angle, the pressure of concrete casting and the impact force of concrete vibrating are easy template
Now float shrink or tension and relaxation and there is faulting of slab ends, if screw rod to reinforce it is not firm, it is possible that spillage and run mould, go out concrete
It now sheds tears line, voids and pits, serious influence concrete solid quality；Due to the particularity of constructing tunnel, two lining concrete moulds
Pallet vehicle must assure that Construction traffic is passed through from trolley door frame, so the door frame bottom of formwork jumbo cannot achieve rigidity branch
Support, the pressure when being poured concrete can make two sides door frame to central reduction, also be easy that concrete seam is made faulting of slab ends occur.Separately
The reinforcing screw rod of outer this formwork jumbo is especially more, has lower arc template to the reinforcing screw rod of door frame, has lower arc template to ground
Screw rod is reinforced, screw rod is exactly to require construction personnel to reinforce rotation to hold out against reinforcings, more than recruitment and large labor intensity, simultaneously because area
Face, which is excavated, mostly uses big machinery to carry out excavation construction, so flue dust is larger in tunnel, since two lining formwork jumbos are there are door frame,
Oil smoke is not easy that tunnel is discharged, and seriously affects construction.There is presently no a kind of rigidity, and strong, environmentally friendly and structurally reasonable tunnel double-lining mixes
Solidifying soil construction formwork trolley.
Summary of the invention
Object of the present invention is to solve current tunnel double-lining concrete blinding trolley defect present in construction, thus open
A kind of tunnel double-lining concrete construction is without door frame formwork jumbo.
Technical scheme is as follows：
Two tracks are placed on the ground of tunnel longitudinal direction, place two traveling wheels on every track, on each traveling wheel respectively
Fixed lifting traveller, lifting slide rod sleeve is in lifting sliding slot, and lifting sliding slot perforation is embedded on bottom beam, and lifting traveller upper end is solid
It is scheduled on lifting cylinder telescopic end, lifting cylinder fixing end is fixed on bottom beam, a side sliding slot is set between three foundation beams respectively,
It is connected with each other between bottom beam and side sliding slot by attachment beam, oil cylinder in a tune is respectively inlayed in each side sliding slot both ends, is adjusted
Middle oil cylinder telescopic end fixes a side sliding column respectively, and sliding column sleeve in side is in side sliding slot, fixed hydraulic case on attachment beam,
Step of getting on the bus is respectively set in setting driving platform on bottom beam, driving platform both ends, and guardrail, attachment beam side is arranged in driving platform two sides
Elevating screw is installed in portion, and lead screw is reinforced in installation between bottom beam and side arc template, and upper arc template and side arc template pass through the pin hinge that is hinged
Even, upper arc template sets several transverse beams below, in the middle part of the transverse beam of front end installation adjust in instrument, every transverse beam and upper arc template it
Between fix a plurality of uprights, a cantilever beam and two operation platforms, side arc oil cylinder fixing end are fixed in every piece of side arc template
It is fixed in transverse beam, arc oil cylinder 7 telescopic end in side is hinged on a cantilever beam.
Design structure of the present invention is reasonable, and stable mechanical performance is easy to operate, and centering uses infrared line adjusting device, fixed
Quick and precisely, whole trolley surrounding and bottom form closed structure, and stability is good for position, and integral mold plate rigid is high, deformation
Measure small, channel available space is big, and Construction traffic operation is smooth, and ventilation strip can pass through, before the more advantageous tunnel of channel large space
The flue dust discharge for holding face, improves the construction environment in tunnel, so reaching the tunnel for meeting quality safety requirement
Two lining concrete constructions are without door frame formwork jumbo.
Detailed description of the invention
Attached drawing 1 is schematic view of the front view of the invention.
Attached drawing 2 be attached drawing 1 of the present invention along A-A to left view the schematic diagram of the section structure.
