Problems solved by technology

[0004] When the slope is too large, the conventional beam body and track bed are adopted, and the track bed tends to slide downhill relative to the beam body, forming an unstable structure and affecting the safety of the upper structure

Embodiment Construction

[0028] The present invention will be described in detail below in combination with specific embodiments.

[0029] The invention relates to a toothed step surface beam structure under the condition of a large slope, the structure includes upright piers 1 at the upper and lower ends, and a longitudinal toothed step surface beam body 3 is carried above the two ends of the pier 1, and the toothed step surface A track bed 4 is arranged above the beam body 3 .

[0030] The surface of the tooth-shaped stepped beam body 3 is uniformly provided with a transverse strip-shaped tooth structure. The bar-shaped tooth structure on the surface of the tooth-shaped step surface beam body 3 is arranged horizontally or segmentally at intervals. The bar-shaped tooth structure on the surface of the toothed stepped surface beam body 3 has two contact surfaces, one contact surface is a horizontal surface, the other contact surface is a vertical surface, or both contact surfaces are inclined surfaces...

Abstract

The invention relates to a tooth-shaped step surface beam body structure under a large slope condition, which comprises vertical piers at the upper end and the lower end, a longitudinal tooth-shaped step surface beam body is borne above the piers at the two ends, and transverse strip-shaped tooth structures are uniformly arranged on the surface of the tooth-shaped step surface beam body. Under thecondition of large gradient, the motion trend of the upper structure can be eliminated, the stress relation can be effectively simplified, and the design and construction workload is reduced. The structural stability of the part above the beam body is improved.

Description

technical field [0001] The invention relates to the technical field of bridge structure construction, in particular to a toothed stepped surface beam structure under the condition of large slope. Background technique [0002] In recent years, the capacity of rail transit has been slightly surplus and needs to be transformed and upgraded. However, the rapid development of the tourism industry and the strong demand for transportation in scenic spots have led to the rapid development of tourist rail transit. Tourist rail transit is limited by terrain and line travel, and often adopts super large longitudinal slopes. Different from the previous rail transit, the tourist track is a combination of cable railway, cog railway, suspended monorail, straddle monorail, wheel rail and other different types of rail transit. [0003] When the rack railway is used, the longitudinal slope of the line can be close to 500‰, while the maximum slope of our conventional wheel-rail system railway...
