Problems solved by technology

However, the currently used parallel double-hole underground interchange has a large area and difficult site selection; multiple interchange tunnel constructions are required in a limited space, and the construction period is long, which has a great impact on the pipelines and buildings around the interchange; Influenced by construction, the linear index of the ramp is not easy to guarantee, etc.

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the drawings:

[0026] See figure 1 , The present invention includes a crossed east-west main tunnel 1, and a north-south main tunnel 2. The east-west main tunnel 1 passes through the north-south main tunnel 2, and has an east junction 3, a north junction 4, a west junction 5, and a south junction 6 There are two intersections, east-to-north right-turn ramp tunnel 7 is connected between east-junction 3 and north-junction 4, and north-to-east left ramp tunnel 8 is connected; north-to-west right-turn ramp 9-2 is connected between north junction 4 and west junction 5 , West-to-north turn left ramp 9-1, layered in the northwest connecting tunnel 9; West-to-south right-turn ramp tunnel 10 is connected between West-to-south intersection 5 and South intersection 6; south-to-west turn left ramp tunnel 11; South intersection 6 and Donglu Junction 3 are connected to the south-to-east right-turning ra...

Abstract

The invention discloses an underground interchange. The underground interchange comprises an east-west main tunnel and a north-south main tunnel which intersect with each other, wherein the east-west main tunnel is positioned on a lower side of the north-south main tunnel; two ends of the east-west main tunnel are taken as an east road junction and a west road junction respectively; two ends of the north-south main tunnel are taken as a south road junction and a north road junction; an east-to-west right-turn ramp and a north-to-east left-turn ramp are connected between the east road junction and the north road junction; a west-north connection tunnel is connected between the north road junction and the west road junction; a west-to-south right-turn ramp and a south-to-west left-turn ramp tunnel are connected between the west road junction and the south road junction; an east-west connection tunnel is connected between the south road junction and the east road junction. The underground interchange has the advantages of simple structure, need of small underground space area, short building period, low cost, easiness in ensuring a line index, prevention of traffic flow intersection, high vehicle passing efficiency, low energy consumption, and high security performance; the problem of interchange of underground tunnels can be solved well.

Description

Technical field [0001] The invention relates to the field of urban three-dimensional traffic, in particular to an underground interchange. Background technique [0002] Large-scale urbanization has led to a sharp decrease in the urban per capita road area, and ground transportation has become increasingly congested. Major cities have begun to build three-dimensional transportation. After a period of practice, the disadvantages of low environmental protection and landscape benefits of elevated roads have gradually become prominent, and major cities in the world have turned to the development of underground transportation systems. With the construction of urban underground highways, urban underground interchanges have emerged in large numbers. However, the currently used parallel double-hole underground interchange has a large area and is not easy to select a location; multiple interchange tunnel constructions are required in a limited space, and the construction period is long, w...
