Dense-column narrow-span high-lower-layer type city-crossing overhead road

Abstract

The invention discloses a dense-column narrow-span high-lower-layer type city-crossing overhead road.The dense-column narrow-span high-lower-layer type city-crossing overhead road is a high-lower-layer overhead road constructed in the mode that narrow-span road slab beams are supported by densely-arranged stand columns.High-lower-layer small-car special channels are expanded between the stand columns below the road surface, safety rails and steps or ramps for upward and downward passing are arranged on the boundaries of the two sides of the overhead road, the road surface is connected with all intersecting ground roads through communication slopes, and a new traffic dispersion mode that the original traffic function is undertaken by the road surface, and car-type small vehicles pass through the urban area through high-lower-layer small-car special channels is formed.The dense-column narrow-span high-lower-layer type city-crossing overhead road is novel in structure, reasonable in arrangement and simple and rapid in construction, cost is saved, various construction modes and various roadway configurations can exist, the high-lower-layer small-car special channels can be located on the ground, buried in the ground in a half mode, shallowly buried in the ground or deeply buried into the underground, and two-layer or more-layer parallel or intersected arranging can be conducted.The dense-column narrow-span high-lower-layer type city-crossing overhead road is suitable for reconstruction and application of vehicle saturated roads, can be additionally constructed on existing common roads, and can also be constructed on a lower layer or an upper layer of an existing overhead road.

Description

technical field [0001] The invention belongs to the improvement of urban roads, in particular to a kind of urban crossing elevated road with dense columns, narrow spans, low floors and high heights. technical background [0002] The development of science and technology has made cars a necessity in people's lives. However, extremes of things will lead to opposites. Excessive car ownership has caused the saturation of modern urban roads and serious congestion, forming a common urban problem that is difficult to solve in the 21st century. In the existing technology, in addition to widening the roads, the improvement of urban traffic efficiency generally uses elevated roads and tunnels through the city to guide the traffic flow. The former is to develop into the air, and the air passage is elevated to guide the traffic to take shortcuts, but it is expensive and affects the city. environment and landscape; the latter diverts vehicles by drilling and building underground traffic ...

Problems solved by technology

In the existing technology, in addition to widening the roads, the improvement of urban traffic efficiency generally uses elevated roads and tunnels through the city to guide the traffic flow. The former is to develop into the air, and the air passage is elevated to guide the traffic to take shortcuts, but it is expensive and affects the city. The environment and landscape; the latter diverts vehicles by drilling and building underground traffic pipelines, which requires high technical requirements and huge construction costs, which is beyond the reach of ordinary cities
