Description
Technical field
The utility model relates to a kind of tunnel double-lining concrete blinding trolley, specifically a kind of tunnel double-lining concrete construction
Without door frame formwork jumbo, belong 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.
Utility model content
The utility model aim is the current tunnel double-lining concrete blinding trolley defect present in construction of solution, thus
A kind of tunnel double-lining concrete construction is disclosed without door frame formwork jumbo.
The technical solution of the utility model is as follows:
Two tracks are placed on the ground of tunnel longitudinal direction, two traveling wheels are placed on every track, on each traveling wheel
Fixed lifting traveller respectively, in lifting sliding slot, lifting sliding slot perforation is embedded on bottom beam lifting slide rod sleeve, is gone up and down on traveller
End is fixed on lifting cylinder telescopic end, and lifting cylinder fixing end is fixed on bottom beam, is set a side between three foundation beams respectively and is pushed away
Sliding slot is connected with each other between bottom beam and side sliding slot by attachment beam, and oil in a tune is respectively inlayed in each side sliding slot both ends
Cylinder, oil cylinder telescopic end fixes a side sliding column respectively in tune, and sliding column sleeve in side is in side sliding slot, fixer on attachment beam
Case is pressed, step of getting on the bus is respectively set in setting driving platform on bottom beam, driving platform both ends, and guardrail is arranged in driving platform two sides, even
Beam side installation elevating screw is connect, lead screw is reinforced in installation between bottom beam and side arc template, and upper arc template and side arc template pass through hinge
Even pin is hinged, and upper arc template sets several transverse beams below, and instrument in adjusting, every transverse beam and upper arc are installed in the middle part of the transverse beam of front end
A plurality of uprights are fixed between template, and a cantilever beam and two operation platforms, side arc oil cylinder are fixed in every piece of side arc template
Fixing end is fixed in transverse beam, and arc oil cylinder 7 telescopic end in side is hinged on a cantilever beam.
The utility model design structure is reasonable, and stable mechanical performance is easy to operate, and centering uses infrared ray adjustment dress
It sets, fast and accurate for positioning, whole trolley surrounding and bottom form closed structure, and stability is good, and integral mold plate rigid is high,
Deflection is small, and channel available space is big, and Construction traffic operation is smooth, and ventilation strip can pass through, the more advantageous tunnel of channel large space
The flue dust of road front end face is discharged, and improves the construction environment in tunnel, so reaching one meets quality safety requirement
Tunnel double-lining concrete construction is without door frame formwork jumbo.
Detailed description of the invention
Attached drawing 1 is the schematic view of the front view of the utility model.
Attached drawing 2 be the utility model attached drawing 1 along A-A to left view the schematic diagram of the section structure.
The reference numerals are as follows: upper arc template 1, side arc template 2, hinge pin 3, column 4, transverse beam 5, cantilever beam 6, side
