Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Such as Figure 5 As shown, in the method for transporting and erecting prefabricated beams on the steep slope of the bridge-tunnel connecting section in the mountains and canyons of the present invention, the following processes are specifically included: beam field layout, prefabricated beam production, beam transportation road layout, special beam lifting machine layout, prefabricated beam transportation, and beam lifting Erection, erection machine assembly, prefabricated girder erection.

[0032] Among them, such as figure 1 and figure 2 As shown, the beam field 1 is arranged on a relatively gentle slope near the side of the prefabricated beam to be erected. Preferably, the beam field 1 is arranged near the outer side of the precast beam to be erected, leaving a certain distance from the bridge to meet the roa...

Abstract

The method for transporting and erecting prefabricated girders on the steep slope of the bridge-tunnel connecting section of the present invention specifically includes the following processes: beam field layout, prefabricated beam production, beam transportation road layout, special beam lifting machine layout, prefabricated beam transportation, beam lifting erection, erection Assembly of bridge cranes and erection of prefabricated girders. The method for transporting and erecting prefabricated beams on the steep slope of the bridge-tunnel connecting section in the mountains and canyons of the present invention sets special beam transport roads according to local conditions and uses beam lifting machines with asymmetrical feet for construction, slows down the longitudinal slope of the transport road, reduces safety risks, and is compactly arranged. It is convenient to build, saves temporary land use, shortens the transportation path, effectively improves work efficiency and reduces economic costs.

Description

technical field [0001] The invention belongs to the field of road and bridge construction, and relates to a method for transporting and erecting prefabricated girders on steep slopes in areas connected by bridges and tunnels in high mountains and canyons in highway projects. Background technique [0002] At present, in the field of highway construction, the superstructure of general highway bridges generally adopts the method of prefabricated beams. The prefabricated bridges are arranged in the beam yard in the line or at a relatively gentle position, and the prefabricated beams are completed by horizontal transportation in the line or a relatively gentle road transportation erection position. Erection. This method is unitary and economical, and can be better used in ordinary road and bridge construction. [0003] However, for highway bridges in high mountains and canyons, especially prefabricated beam yards arranged outside the line, transportation has become a relatively ...
