Assembled urban interchange system

Abstract

The invention provides an assembled urban interchange system. The assembled urban interchange system comprises a linear type bridge section, wherein the linear type bridge section comprises a shallow-buried steel frame foundation formed by steel cross girders through connection, a plurality of steel stand columns are vertically arranged on the shallow-buried steel frame foundation, a beam body formed by steel cross girders through connection is arranged at the top end of each stand column, and a bridge floor is paved on the beam body; the linear type bridge section also comprises a monitoring element; a bendable bridge section is combined with the linear type bridge section for use as required; the interchange system can be assembled on site, the occupied road space is small, less traffic interference is caused, after the interchange system is assembled and used, the traffic congestion can be solved, the occupied space is smaller than that of the reinforced concrete interchange system, the assembled urban interchange system can be rapidly constructed and dismounted and cannot permanently occupy the urban space, the scale of the assembled urban interchange system can be increased along with the local traffic flow, and the long-term planned reinforced concrete integrated interchange system can be constructed one time at mature time, and has a middle transition function of relieving the urban traffic pressure in a traffic volume increasing process.

Description

technical field [0001] The invention belongs to the technical field of urban infrastructure, and relates to a truss structure-based urban overpass system that can be assembled. The overpass system is equipped with displacement and internal force detection devices. Background technique [0002] Viaducts have the functions of alleviating urban road traffic congestion and improving urban traffic conditions. They are flourishing in major cities and changing with each passing day. So far, my country has built several large-scale urban viaducts, and small and medium-sized cities have also begun to build small-scale viaducts in urban downtown areas in recent years. [0003] The current urban overpass system is almost all reinforced concrete structures, which occupy a large area and have a great impact on adjacent buildings. The cost is high and the construction period is long. During the construction period, the already congested urban traffic system is even worse. The benefits ar...

Problems solved by technology

[0003] The current urban overpass system is almost all reinforced concrete structures, which occupy a large area and have a great impact on adjacent buildings. The cost is high and the construction period is long. During the construction period, the already congested urban traffic system is even worse. The benefits are not necessarily directly proportional, and there are mainly the following deficiencies: 1) With the development of the surrounding economy and culture, the traffic volume also increases, and the traffic volume of different landmarks and road sections is significantly different. At intersections, the ratio of the economic benefit to construction cost of building comprehensive interchanges is much greater than the ratio of small and medium-sized cities to build small interchanges, and some sections of these small and medium-sized cities have to build interchanges to relieve the increasing traffic pressure and compress the surrounding area. Buildings, when the traffic volume reaches a certain level in the future, will inevitably be overthrown and rebuilt within the life cycle of the existing overpass to meet the future traffic flow; 2) The existing overpass system occupies a large area in common characteristics, and the structural system is heavy, and it is difficult to coordinate with the surrounding environment. The above-ground and underground structures are permanently occupied, which is not conducive to long-term planning and development; 3) The existing reinforced concrete interchange system generally requires a construction period of 2 to 3 years , requires land acquisition and demolition, fence excavation, and traffic closure. These factors will prolong the construction period and have a great impact on the already congested traffic system; 4) The construction of an overpass system generally requires land acquisition and demolition around the original traffic roads. However, the permanent land occupation and permanent buildings formed may not meet the needs of long-term planning and long-term development, resulting in waste of investment; 5) The construction of urban transportation facilities is a gradual process, and in this development transition In the process, there is no transitional solution. We can only wait for the congestion to become unbearable and then carry out transportation infrastructure construction like a boat, which is extremely detrimental to the city's economic, cultural development and city image.

[0004] The above-mentioned deficiencies lead to low economic benefits, large construction investment, long construction period, and a lot of space occupied by the small and medium-sized reinforced concrete interchange system. It may even lead to waste of investment
