Problems solved by technology

The layout of traditional steel temporary bridges is difficult to meet the requirements, which affects the actual cross-section of the river, followed by unavoidable noise
If a permanent concrete bridge structure is adopted, the investment cost is high, the construction speed is slow, and the demolition cost is high

Embodiment 1

[0028] Such as image 3 , Figure 4 and Figure 5 Shown, a kind of temporary temporary bridge device, the simple and easy bridge that is used for temporary erection, comprises the Bailey beam 8 that spans the space under the bridge that the longitudinal space of a plurality of vertical traffic lanes arranges, and the space under the bridge may be a road or a river, described The Bailey beam 8 laterally includes multiple groups of sub-beam frames connected to each other through Bailey pins 17, such as Figure 5 As shown, each sub-beam frame is composed of three Bailey frames arranged in parallel, and the three Bailey frames are connected by cross-connectors 20; the upper and lower chords of the 8 Bailey beams are connected by Bailey pins 17, and the Bailey pins are used specifically. Lightning frame, three pieces in one group, 2X45cm apart, and 90cm apart in the longitudinal direction. Bailey beams are arranged vertically to the carriageway, and the carriageway is arranged a...

Abstract

The invention discloses a temporary bridge device used for a temporarily-erected simple bridge. The temporary bridge device comprises multiple Bailey beams (8) perpendicular to a carriageway and longitudinally arranged at intervals, wherein pavement distribution beams (9) made from I-steel are laid on the Bailey beams (8), bamboo plywoods (10) are laid on the pavement distribution beams (9), and concrete bridge deck slabs (11) are cast on the bamboo plywoods (10) on site to form a pavement. U-shaped bolts (16) connected with the Bailey beams (8) are embedded into the concrete bridge deck slabs (11). End bridge piles are arranged at two ends of each of the Bailey beams (8), middle bridge piles are arranged in the middles, and the end bridge piles and the middle bridge piles support the Bailey beams (8). The whole carriageway is arranged above a riverway, an arrangement form in the bridge direction is reasonable compared with traditional girders, the space above the riverway is fully utilized, a large amount of land acquisition is avoided, and greened both sides are effectively protected. In addition, the number of pile foundations in a river is deceased by arranging a transverse riverway, the construction difficulty is reduced, and meanwhile the water blocking area can be effectively decreased.

Description

technical field [0001] The invention relates to the technical fields of mechanical structure and traffic engineering, in particular to a temporary temporary bridge device. Background technique [0002] Temporary temporary bridge is a simple bridge erected temporarily. The bridge erected for the convenience of construction is for the smooth and convenient passage of construction machinery. Sometimes in order to construct large-scale projects such as subway stations, it is necessary to divert the main road to divert traffic. In particular, there may not be enough space in cities to build temporary access roads, and the construction of temporary access bridge structures on rivers is used to guide traffic, and the general construction requirements are tight. There are many lanes on the main road in the city, and the traffic flow is heavy. How to achieve economical, safe and convenient construction is an important issue that needs to be considered when designing temporary acces...
