a new type of bridge

Abstract

The invention discloses a novel bridge which comprises three arc-shaped main arches, inhaul cables, an annular main bridge and approach bridges. The arc-shaped main arches incline to each other and are drawn close to each other to form a stress whole. Inhaul cable anchors are arranged along the surfaces of the main arches, and each inhaul cable anchor is connected with one inhaul cable. The otherend of each inhaul cable is connected with the surface of the annular main bridge. The approach bridges communicate with the edge of the outer ring of the main bridge, and two or more approach bridgesare arranged according to the terrain and the bridge erection position. The novel bridge has the beneficial effects that the three oblique arc-shaped main arches are used for obliquely pulling a bridge structure of the annular main bridge, only three arch supports land, the bridge easily strides over the water surface of a three-river confluence, no column pier stands in water, and meanwhile, theannular main bridge is used for connecting multiple points. In an urban intersection, no column pier stands on a pavement, traffic is released, and meanwhile, multiple connecting approach bridges canbe arranged according to the terrain and the bridge erection position.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a novel bridge. Background technique [0002] The existing pedestrian bridges used to connect urban traffic intersections generally use straight lines to connect two points, and adopt a multi-column structure, which has a certain hindering effect on traffic. It is difficult to use a single bridge to realize multi-point traffic without affecting traffic. connect. [0003] Existing bridges used for the confluence of the three rivers or crossing multiple waters have too many piers in the waters, which affects the passage capacity of the waters, especially in ecological protection areas, the construction of piers in the water will have a certain impact on the ecology. Contents of the invention [0004] Aiming at the defects of the prior art, the present invention provides a novel bridge, which can effectively solve the above-mentioned problems in the prior art. [0005] In order ...
