U-shaped turnabout culvert road for realizing micro interchange at level crossing of urban built-up area

Abstract

The invention discloses a U-shaped turnabout culvert road for realizing micro interchange at a level crossing of an urban built-up area. The U-shaped turnabout culvert road comprises a major road at a cross-shaped or T-shaped level crossing and a pair of U-shaped turnabout culverts symmetrically arranged on the two sides of the major road. Guide culverts are arranged on the two side edges of a U-shaped opening of each U-shaped turnabout culvert, are positioned in the major road respectively, are symmetrical with the forward and backward directions of the major road, and are obliquely built in parallel with the major road. Circular-arc street crossing culverts are arranged at the bottoms of the U shapes of the U-shaped turnabout culverts. The guide culverts are slowly inclined downwards, and are integrated with the street crossing culverts to form the integrated three-dimensional U-shaped turnabout culverts. According to the U-shaped turnabout culvert road, the problem of traffic congestion, which cannot be solved in the prior art, in the urban built-up area can be solved; and in addition, the U-shaped turnabout culvert road has the positive effects of simple facility structure, low construction cost, freeness from the limitation of spatial conditions, and the like.

Description

technical field [0001] The invention discloses a U-shaped turning culvert road for realizing micro-interchanges of level crossings in urban built-up areas, which is an improvement on cross or T-shaped level crossings that have been completed in existing urban streets and buildings along the street and difficult to be transformed into overpasses. The utility model belongs to the technical field of road, bridge and culvert traffic facilities. Background technique [0002] my country's large cities generally have a history of hundreds of years or even longer, and today's huge traffic flow was not considered during most of the urban construction period. With the continuous increase of urban vehicles and increasingly busy road traffic, it is difficult to make adaptive changes in urban built-up areas because the streets and buildings along the streets have been completed. Traffic congestion has become a major problem in urban operation. Especially road intersections in urban buil...

Problems solved by technology

[0005] The invention provides a U-shaped turning culvert road that realizes micro-overpasses at level crossings in urban built-up areas, and solves the problem of traffic congestion at intersections in urban built-up areas

It cannot be used in urban built-up areas due to its large occupation, and at the same time overcomes the shortcomings of high construction costs and long construction periods
