Road normal length is big, and the length dimension of outer mould trolley is smaller, it is impossible to which primary concreting is complete, utilizes guide rail 13 and motor
14, it can be poured one by one along length of tunnel direction, while reducing the construction infection of cross-operation.According to the design needs with actually apply
Work experience, the travel speed of walking mechanism are designed as 6.7 meters per minute.Wherein, the spacing of two guide rails 13 is 8000 millimeters.
Using the construction of mould trolley outside above-mentioned slope open trench tunnel rectangular configuration lining cutting, wherein outer mould trolley is in place
It is as follows with fixed construction process:
1, walking mechanism is in place
Each two sets of external mold hydraulic jumbo principal and subordinate's walking mechanism, they are hinged on column framework 2.Main walking mechanism is by Y type
After motor 14 drives primary gear speed reducing, then slow down by two-stage chain, walking wheel diameter is Φ 350mm, trolley walking surface need
Hardening is smooth using the compacting of mud knot rubble, guarantees height error in 5cm, rail is that 43kg/m simple guide rail frame 13 is (convenient
It is mobile), sleeper is channel steel 20#, and for interorbital away from according to depending on tunnel cross-section size, motor 14 selects 7.5KW two.Trolley design
The speed of travel about 6.7m/min.
2, outer mould trolley is in place
Outer mould trolley is aligned, and outer mould trolley is first reached lower ring construction location, further according to the data that measurement is told somebody what one's real intentions are, is led to
It crosses and is supported on the horizontal direction oil cylinder of door frame side below the crossbeam pedestal to adjust the lining cutting center of template and the centering of tunnel center, it is left
Right range-adjustable 17cm；The vertical positioning of template is adjusted by the contraction for the door frame lift structure 4 being connected with avris column,
Upper and lower range-adjustable 300mm；Template is adjusted by the side mode top-pushing mechanism 5 that is mounted on door frame and side mode supporting device 7
Position.
3, outer mould trolley is reinforced
Side mode 3 is reinforced after contraposition is accurate, passes through door frame supporting device 6, side mode top-pushing mechanism 5, side mode supporting device 7
And reinforce 10 pairs of trolley formworks of support and reinforce, 3 bottom of side mode is fastened by anchor 8, the walking stringer of side mode 3
Locate the necessary firm support of support screw over the ground on ground.
Illustrate: outer mould trolley reaches in next operation section and outer mould trolley should be polished, and coating release agent.
The outer mould trolley of above-mentioned slope open trench tunnel rectangular configuration lining cutting and its construction scattered break decking with traditional
Compare with bowl buckle strutting system and its construction method, has the advantage that
1, rectangle external mold hydraulic lining trolley is high using overall steel modular system rigidity, stability is good, ensure that concrete knot
Structure globality and structure size meet design requirement, also ensure that concrete appearance is closely knit, beautiful.
2, outer mould trolley operating automation degree is high, and it is whole that the walking of rectangle external mold hydraulic lining trolley is all made of motor 14
Driving, cover half, demoulding are automatically controlled using hydraulic cylinder, and easy to operate, process is simple, and labor intensity is low, reduce it is artificial and
Lifting machine cost；Trolley the whole series are fixed automatically at mould, are reduced the materials such as temporary support in conventional method, have been saved and be constructed into
This, and be conducive to keep live civilization clean and tidy.
3, work efficiency is high, and rectangle external mold hydraulic lining trolley is to support large-scale steel structure mould with combined steel structure door frame
Plate system, using electric walking, speed of travel 6.7m/min, in place and reinforcing is fast and convenient, and formwork reinforcement is not required to construction and wears
