Abstract

The utility model provides a three-layer flyover. The three-layer flyover comprises a base-layer road surface, a middle-layer bridge surface and an upper-layer bridge surface, wherein slope surfaces of the middle-layer bridge surface and the upper-layer bridge surface are both connected to the base-layer road surface; the joint of the middle-layer bridge surface and the base-layer road surface is below the upper-layer bridge surface; the upper-layer bridge surface and the middle-layer bridge surface are overlapped in vertical projection; the base-layer road surface is wider than the middle-layer bridge surface and the upper-layer bridge surface. By adopting a three-layer overlapped structure, the three-layer flyover has the advantages of effectively utilizing a three-dimensional space, greatly preventing traffic congestion and alleviating traffic pressure.

Description

A kind of three layers of overpass bridge

Technical field

The utility model relates to a kind of three layers of overpass bridge.

Background technology

The Chinese utility model patent that is CN200920319252.5 as application number discloses a kind of multilevel intersection system of crossroad, and the multilevel intersection system of this crossroad, by three layer construction, can be alleviated traffic pressure to a great extent.But in the design of the multilevel intersection system of this crossroad, laterally take up an area still larger, for vertically to solid space under-utilized, therefore for the very large fork in the road of traffic pressure, still cannot well guarantee not block up.

Utility model content

For solving the problems of the technologies described above, the utility model provides a kind of three layers of overpass bridge, and these three layers of overpass bridges, by three ply structures, effectively utilize solid space, avoid greatly traffic congestion, slow down traffic pressure.

The utility model is achieved by the following technical programs.

A kind of three layers of overpass bridge that the utility model provides, comprise basic unit road surface, intermediate deck and upper deck of bridge; The domatic basic unit road surface that is all connected to of described intermediate deck and upper deck of bridge; The junction on described intermediate deck and basic unit road surface is positioned at upper deck of bridge below; Described upper deck of bridge and intermediate deck overlap in upright projection; Described basic unit width of roadway is greater than the width of intermediate deck and upper deck of bridge.

Height between described intermediate deck and upper deck of bridge is greater than 4 meters.

Height maximum value between described basic unit road surface and intermediate deck is greater than 4 meters.

The width of described intermediate deck and upper deck of bridge is greater than 5 meters.

Described basic unit road surface is at least wide 5 meters than upper deck of bridge or intermediate deck.

The beneficial effects of the utility model are: by three ply structures, effectively utilize solid space, avoid greatly traffic congestion, slow down traffic pressure.

The specific embodiment

Further describe the technical solution of the utility model below, but described in claimed scope is not limited to.

A kind of three layers of overpass bridge as shown in Figures 1 to 4, comprise basic unit road surface 1, intermediate deck 2 and upper deck of bridge 3; The domatic basic unit road surface 1 that is all connected to of described intermediate deck 2 and upper deck of bridge 3; Described intermediate deck 2 is positioned at upper deck of bridge 3 belows with the junction on basic unit road surface 1; Described upper deck of bridge 3 and intermediate deck 2 overlap in upright projection; Described basic unit road surface 1 width is greater than the width of intermediate deck 2 and upper deck of bridge 3.

Height between described intermediate deck 2 and upper deck of bridge 3 is greater than 4 meters.

Height maximum value between described basic unit road surface 1 and intermediate deck 2 is greater than 4 meters.

The width of described intermediate deck 2 and upper deck of bridge 3 is greater than 5 meters.

Described basic unit road surface 1 is at least wide 5 meters than upper deck of bridge 3 or intermediate deck 2.

Be the first embodiment of the present utility model as shown in Figure 1 and Figure 2, as above-mentioned setting, and overpass bridge is T font.This embodiment is applicable to the junction of three roads that meets arbitrarily width.

Be the second embodiment of the present utility model as shown in Figure 3, Figure 4, as above-mentioned setting, and overpass bridge is cross.This embodiment is applicable to the crossroad that meets arbitrarily width.

In the utility model, intermediate deck 2 and upper deck of bridge 3 can design any track quantity, be generally 2 tracks or 4 tracks, basic unit road surface 1 goes out two tracks with respect to intermediate deck 2, upper deck of bridge 3 are at least wide, smooth and easy to guarantee driving, and every lane width is at least 2.5 meters, so basic unit road surface 1 is at least wide 5 meters than upper deck of bridge 3 or intermediate deck 2.

During use, take the second embodiment as example, through vehicles can pass through from intermediate deck 2, keep to the right in right-hand rotation vehicle Ze Ke basic unit road surface 1, left turning vehicle can be kept to the left to upper deck of bridge 3, can Vehicle Driving Cycle space, fork in the road be realized better and being utilized thus, further alleviate traffic pressure.

For the setting on sidewalk, can be by prior art, the mode by underground passage or pedestrian overcrossing realizes easily, to guarantee the effective utilization to space.
