Abstract
The invention discloses a method for paving a bridge surface through four-machine linkage. The method comprises the following steps: (1), arranging a vibrating beam track: respectively and uniformly burying a plurality of track supporting bars on the inner side of the bridge surface along with an anti-collision guardrail base of the bridge surface, and paving the vibrating beam track on the track supporting bars; (2), pouring and paving concrete: transporting the concrete to the bridge surface by utilizing a concrete pump vehicle, firstly performing primary vibrating leveling, and then paving a vibrating beam, purifying syrup and performing fine leveling by utilizing a full-automatic roll shaft paver; (3), troweling the finished bridge surface: troweling the finished bridge surface by adopting a troweling machine after the initial set of the concrete until a top surface is smooth; (4), paving and maintaining the bridge surface: moisturizing and maintaining the troweled bridge surface by adopting an atomizer in an atomizing manner after the initial set of the concrete, and paving geotextile and performing water spraying maintenance after the concrete is troweled; (5), roughening the top surface of the paved bridge surface: after the strength of the concrete achieves 50-70%, removing epidermal laitance by adopting a milling machine, so that a rough surface is exposed. The method disclosed by the invention is high in mechanization level, the whole bridge surface pavement is formed at a time, the bridge surface is flawless, and the planeness is good.
Description
Technical field:
The invention belongs to a kind of architectural construction technology, particularly a kind of " four machine interlocks " deck paving method.
Background technology:
Deck paving is the important component part of bridge vehicle-driving, and it bears the pressure of wheel, impact and shear action, and its quality and useful life longevity are directly connected to the safety of driving, comfortableness and bridge durability.At present, unit in charge of construction generally adopts vibration fine strain of millet+manually wipe one's face+artificial hacking construction technology to carry out deck paving, and this technique often there will be that seam is many, poor flatness, bridge floor cracking and the common quality defect such as end face is smooth.
Summary of the invention:
Object of the present invention is just to overcome above-mentioned the deficiencies in the prior art, and provides a kind of " four machines interlocks " deck paving method, and the method mechanization degree is high, the one-shot forming of deck paving view picture and free from flaw, and planeness is good.
As above conceive, technical scheme of the present invention is: a kind of " four machine interlocks " deck paving method, is characterized in that: comprise the steps:
1. vibrating beam track is set: along bridge floor anticollision barrier base respectively to pre-buried laying even inside bridge floor many rail supported muscle, vibrating beam track laying is on track brace rod;
2. build concrete of mating formation: utilize concrete mixer by concrete conveyance to bridge floor, first by leveling of shaking at the beginning of vibrating beam, recycle full-automatic roll shaft paver paving vibrating beam, carry slurry, essence is flat;
3. face troweling is received: adopt the floating receipts face of finisher after concrete initial set, until end face is smooth;
4. deck paving maintenance: adopt nebulizer moisture-keeping maintaining after concrete initial set, concrete-face closure terminates rear laying geotextiles watering maintenance;
5. end face dabbing of mating formation process: after concrete arrives intensity 50-70%, adopts milling machine to remove epidermis laitance, exposes rough surface.
Above-mentioned concrete vibrating beam orbit elevation of top surface is the elevation control of deck paving concrete.
Above-mentioned concrete vibrating beam orbit adopts [10 reinforcing bars.
Above-mentioned along bridge floor anticollision barrier base respectively to inner side every 0.5 meter lay one rail supported muscle.
Above-mentioned rail supported muscle is made up of two that are embedded on bridge deck vertical Φ 16 reinforcing bars and horizontal Φ 16 reinforcement welding.
The present invention has following advantage and good effect:
1, the present invention is by vibrating beam, full-automatic roll shaft paver and the mutual combination acts synergistically of finisher, and mechanization degree is high, can save a large amount of labour, improves construction precision.And make the one-shot forming of deck paving view picture, without longitudinal constuction joint, good integrity.
2, the present invention adopts finisher to smear pressure receipts face, and pave-load layer top of concrete smears the real free from flaw of densification, and planeness is good.
3, vibrating beam track of the present invention repeatedly can have enough to meet the need use, and material is fully used.
Accompanying drawing illustrates:
Fig. 1 is process chart of the present invention.
Detailed description of the invention:
As shown in the figure: a kind of " four machine interlocks " deck paving method, comprises the steps:
One, concrete vibrating beam orbit 1 is set: along anticollision barrier base respectively to 0.5 meter of pre-buried laying rail supported muscle inside bridge floor 2, brace rod is by Φ 16 reinforcement fabrication, for ensureing that vibrating beam track has enough rigidity and stability, lay one brace rod for every 0.5 meter, one brace rod is made up of two that are embedded on bridge deck vertical Φ 16 reinforcing bars and horizontal Φ 16 reinforcement welding.After the pre-buried end of vertical reinforcement of brace rod, in strict accordance with the altitude data welding transverse reinforcement that measurement class provides.Concrete vibrating beam orbit is laid on the transverse reinforcement of a welding, and its elevation of top surface is the elevation control of deck paving concrete.
Described concrete vibrating beam orbit adopts [10 reinforcing bars.
Two, build concrete of mating formation: concrete mixer is by concrete conveyance to bridge floor, and hand fit evenly shakeouts, leveling of shaking at the beginning of first vibrating beam, more full-automatic roll shaft paver 4 spreads vibrating beam 3, carries slurry, essence is put down.
Three, receive face troweling: adopt the floating receipts face of driving finisher 5 after concrete initial set, first carry out longitudinal direction twice, then carry out that transverse direction twice is just flat just smears, while frontier inspection survey planeness of wiping one's face, planeness carries out careful wiping one's face until end face is smooth after meeting specification again.
Four, deck paving maintenance: adopt nebulizer moisture-keeping maintaining after concrete initial set, concrete-face closure terminates rear laying geotextiles watering maintenance, and curing time is no less than 7 days.
Five, end face dabbing of mating formation process: after concrete arrives intensity 70%, adopts milling machine 6 laterally to remove epidermis laitance, exposes rough surface.
