Bidirectional plate stressed longitudinal and transverse beam concrete superstructure of level crossing bridge

Abstract

The invention discloses a bidirectional plate stressed longitudinal and transverse beam concrete superstructure of a level crossing bridge. The superstructure comprises an edge beam structure system, which defines a space; a longitudinal and transverse beam structure system arranged in the space defined by the edge beam structure system and comprises a plurality of longitudinal beam components which extend in the longitudinal direction and are arranged at intervals in the transverse direction and a plurality of transverse beam components which extend in the transverse direction and are arranged at intervals in the longitudinal direction, so that a net-shaped structure with a plurality of gaps is formed in the edge beam structure system; and a top plate structure system which comprises a plurality of top plates, wherein each top plate covers the corresponding gap. As an upper beam body structure of a permanent intersection bridge, the bidirectional plate stressed longitudinal and transverse beam concrete superstructure can be applied to a level crossing of a regular multi-direction intersection at the center of a road, so that the problem that vehicles and pedestrians in different directions have intersection conflicts at the urban intersection is effectively solved, and the condition of traffic jam is relieved.

Description

technical field [0001] The invention relates to highway bridge technology, in particular to a longitudinal and horizontal beam concrete superstructure of a two-way slab of a level crossing bridge. Background technique [0002] With the rapid economic development of my country's big cities in recent years, urban traffic congestion is becoming more and more serious. Among them, for level intersections in urban roads (that is, the part where two or more roads intersect on the same level, referred to as level intersections), there are vehicles and pedestrians with different driving directions on the intersecting roads. It is prone to problems such as slowing down of driving speed and traffic congestion, which seriously affects the driving safety of urban roads. [0003] In order to alleviate traffic congestion at level intersections, methods such as widening intersections, increasing the number of driving lanes, establishing interchange bridges, and simple temporary bridge stru...

AI Technical Summary

Problems solved by technology

However, due to the completion of road layout in most of our cities, limited space for road widening, expensive land, short service life of temporary bridge structures at simple level crossings, temporary structures at simple level crossings that cannot cope with complex road conditions, and high cost of interchanges, etc. The reason is that the above method cannot be effectively applied and implemented, and it is difficult to solve the problem of crossing conflicts between vehicles and pedestrians in different driving directions on various intersecting roads at urban level intersections for a long time
