Device for bridge deck construction and construction method thereof

Technical Field

The application relates to the field of bridge construction equipment, in particular to a device for bridge deck construction and a construction method thereof.

Background

Bridge deck pavement refers to a process of paving a concrete protective layer on a bridge deck to prevent wheels from directly wearing a bridge deck plate and diffusing wheel loads, and also provides a smooth and anti-skid running surface for vehicles.

The utility model provides a three roller paves evener is also known as three roller vibration roof beam, a kind of concreting equipment that often uses in bridge deck pavement, as shown in fig. 1, a three roller vibration roof beam includes support body 1, support body 1 includes two fixed plates 11, first roller 2 has been arranged in proper order to the level between two fixed plates 11, second roller 3 and third roller 4, wherein first roller 2 alone drive rotation, first roller 2 is used for stirring the concrete surface of pouring, play the effect of carrying thick liquid, second roller 3 and the synchronous rotation of third roller 4, second roller 3 can produce the vibration, be responsible for with concrete leveling and compaction, third roller 4 provides the driving force and drives support body 1 forward.

At present, one construction mode mainly adopted for bridge deck pavement is that two concrete base bands 6 are respectively poured on two sides of a bridge deck in advance, and the two base bands 6 are equivalent to side dies for pouring concrete on the bridge deck and are used as moving tracks of vibration beams. After the base bands 6 are hardened, the vibration beam is erected between the two base bands 6, one end of each of the second roll shaft 3 and the third roll shaft 4 is erected on one base band 6, and the first roll shaft 2 is placed on one side of the advancing direction of the vibration beam. During construction, concrete is poured on the bridge deck, the vibrating beam is made to advance, the concrete which is lifted by the first roll shaft 2 is compacted by the second roll shaft 3 and is flush with the surface of the base band 6, and finally the base band 6 and the newly poured concrete form a pavement layer of the bridge deck.

When pouring concrete, constructors can generally pour the thickness of the concrete between the base bands to be thicker, so that the vibration beam can fully contact the newly poured concrete, and the concrete is compacted. However, in the construction site, the problem that the local part of the poured concrete is too thick or the slump of the concrete is small often occurs, the second roll shaft moves forwards and cannot quickly push down the concrete, the vibrating beam can be jacked up to move forwards, the concrete surface of the part cannot be flush with the surface of the base band, and therefore constructors need to retreat the vibrating beam for a certain distance, and after manually shoveling out a part of the concrete, the vibrating beam is driven to move forwards, so that a great amount of time is wasted, and the construction efficiency of pouring the concrete on the bridge deck is seriously reduced.
