A light-duty truss bridge integrated layer full-width construction device and its construction method

Abstract

The invention relates to an integrated layer whole-width construction device for a light truss type bridge and a construction method of the construction device. The integrated layer whole-width construction device comprises a vibration beam for vibrating on a bridge deck base layer to form an integrated layer, wherein a moving wheel is arranged between the vibration beam and the bridge deck base layer; a vibration grout extracting roll shaft is arranged at the bottom of the vibration beam; and the length of the vibration grout extracting roll shaft is equal to or smaller than the width of the integrated layer. According to the integrated layer whole-width construction device disclosed by the invention, with the adoption of the structure, the situation in the prior art that the bottom roll shaft can cover the structure of a part of the integrated layer on the bridge deck base layer only is avoided, and as the length of the roll shaft is larger than or equal to the width of the integrated layer on the bridge deck base layer, the vibration beam carries out single stroke only in the length direction of the bridge deck base layer so as to realize whole-width construction, and the integrated layer whole-width construction device has the beneficial effect of high construction efficiency and ensures better smoothness and tidiness of the integrated layer formed on the bridge deck base layer.

Description

technical field [0001] The invention relates to the field of bridge deck construction devices, in particular to a light-duty truss bridge integrated layer full-width construction device and a construction method thereof. Background technique [0002] The concrete pavement of the integrated layer of the bridge deck adopts the method of vertically dividing into sections, dividing the left and right sides with the center of the bridge as the boundary in the horizontal direction of the bridge, and the method of single-width integral pouring. Transported to the vicinity of the pavement, the concrete pump truck will distribute the material evenly, and the vibrating rod combined with the light vibrating beam will vibrate the construction method. Among them, the three degrees of bridge deck pavement (thickness, strength, flatness) and cracks are the bridge deck pavement construction methods. The control key, especially the control of flatness, will directly affect the construction q...

AI Technical Summary

Problems solved by technology

At present, the three-roller shaft used in the ordinary construction of bridge deck pavement is relatively heavy. It is easily deformed and deflected by manual dragging. The flatness is generally not well controlled, labor-intensive and time-consuming. The construction of the integrated layer of the bridge deck is usually divided into two sections on the left and right. There are several disadvantages in such a construction device:

[0003] 1. Due to the use of framed construction, the control of flatness is poor;

[0004] 2. Poor control over cleanliness: Due to the use of framed construction, personnel, vehicles, mechanical equipment, etc. can easily cause pollution on the bridge deck, and the pollution caused by the leakage of grout in the framed pouring side formwork is usually difficult to clean up these secondary pollutions , and it takes time and labor to clean up

[0005] 3. The control of cracks is poor: the thickness of the integral layer is thin, and cracks are easy to appear due to improper construction control. Specifically, the framed construction joints sometimes form cracks due to reasons such as the difference in age of concrete on both sides, and, framed It is difficult to timely construct the cutting seam at the top of the pier, which may easily cause cracks at the top of the pier

[0006] 4. The control of napping is poor: due to the use of framing construction, workers generally stand on both sides for napping, and the control of the line shape and depth of napping is poor, and it is difficult to do it properly
