Beam transporting method for building of double-deck bridges

Abstract

The invention provides a beam transporting method for building of double-deck bridges. The beam transporting method includes the steps of firstly, supporting one end of a main beam (3) on an upper deck (2) and supporting the other end of the main beam (3) on a bridge pier (4); secondly, transporting a lower-deck U-beam (8) to the position of a tip (9) of the lower deck through a beam transporting vehicle (7); thirdly, lifting the lower-deck U-beam (8) to move to a lower-deck falling position (10); fourthly, paving a lower-deck rail (6) on the lower-deck U-beam (8), transporting an upper-deck U-beam (11) to the lower-deck rail (6) through a beam transporting vehicle (5), and lifting the upper-deck U-beam (11) and moving it to an upper-deck falling position (12). By the beam transporting method for building of double-deck bridges, the lower-beck U-beam needed to be transported can be transported to the position right above the lower-deck falling position conveniently rapidly, and the upper-deck U-beam for the upper deck can be transported by the aid of the lower-deck rail conveniently rapidly.

Description

technical field [0001] The invention belongs to the technical field of bridge construction technology, and more specifically relates to a beam transporting method for double-deck bridge construction. Background technique [0002] In the bridge construction industry, especially in the construction of double-deck bridges, for some places, due to the obstruction of objects, the lower U-beams that need to be transported cannot be directly transported to the drop beam position by the beam transporter, but can only be transported to the drop beam near the lower layer. position, and then transfer by means of equipment lifting or laying of conveying channels, which leads to low transfer efficiency of the lower U-beam, increases the labor intensity of construction personnel, and there are safety hazards in the transfer. At the same time, when the prior art is building a double-deck bridge, the upper deck and the lower deck interfere with each other. To transport the upper U-beam, it ...

Problems solved by technology

[0002] In the bridge construction industry, especially in the construction of double-deck bridges, for some places, due to the obstruction of objects, the lower U-beams that need to be transported cannot be directly transported to the drop beam position by the beam transporter, but can only be transported to the drop beam near the lower layer. position, and then transfer by means of equipment lifting or laying conveying channels, which leads to low transfer efficiency of the lower U-beam and increases the labor intensity of construction personnel, and there are still potential safety hazards in the transfer

At the same time, when the prior art is building a double-deck bridge, the upper deck and the lower deck interfere with each other. To transport the upper U-beam, it is necessary to lay a delivery track, then transport the upper U-beam through the delivery track, and then remove the delivery track, which not only increases the workload, resulting in increased labor intensity and affecting construction efficiency
