Abstract

The invention relates to an integral multifunctional lifting structure of a steel-structured overpass, which is combined with patent applications of ' urban intersection module assembly integral lifting ramp door-opening type steel-structured overpass ' and ' well foundation lifting column door-opening type lifting ramp ' for the integral lifting overpass '. The overpass has the multi-functional lift effect and lies in: the height of the main span bridge foundation can be set in an ultra-low limit mode (based on the passing of buses), the ramp configuration can be greatly shortened through the ultra-low main span bridge, and the short-distance ramp is more beneficial to the simple realization of a door-opening type lifting structure while the road occupation is reduced. The main span bridge body rises to reach the national bridge standard, if the whole body rises as keeping the normal state (or taking descending as the normal state), a ceiling without great obstruction is formed, the normal traffic of the vehicles at the original ultrahigh crossing is recovered, and the vehicle flow peak can be descended at any time to adjust the three-dimensional traffic of the traffic flow peak. The multifunctional sectional lifting further increases the flexibility of adjusting the traffic flow of the longitudinal and latitudinal roads and keeping the normal state. The invention relates to an optimal and effective scheme for solving the vehicle congestion at urban level crossings.

Description

Multifunctional sectional lifting structure arrangement of urban road junction integral lifting steel-constructed overpass

Technical Field

The invention relates to urban three-dimensional traffic, in particular to a multifunctional sectional lifting structure arrangement of an urban road junction integral lifting steel-structured overpass.

Background

The vehicle congestion condition at the modern urban traffic crossing is a bottleneck problem which can not be solved for a long time and is also a serious civil subject to be solved urgently by urban traffic. This congestion will become increasingly severe as civilian vehicles continue to increase. The effective method for solving the difficult problem is that the traffic road junction is provided with a three-dimensional traffic facility, most urban road junctions do not have the necessary condition for constructing a large-scale overpass measure, and if a plurality of small bridges are constructed, the urban overall landscape is influenced and not only becomes a barrier for the ultrahigh overweight vehicles to pass, but also is directly influenced by the factors for making a decision on municipal construction. In the modern science and technology era, people expect that the travel difficulty of the people can be solved by means of modern science and technology.

Disclosure of Invention

The invention provides a sectional lifting structure arrangement of an integral lifting steel-structured overpass at an urban level crossing, which is an effective scheme for solving the problems. And the multifunctional lifting structure for solving the vehicle jam of the steel structure overpass at the urban level crossing is formed by the technology of assembling an integral lifting ramp door-opening type steel structure overpass with a patent number 2020109921163 (for a publication document) and an urban intersection module of an applicant, and a technology of 2021102426973 (for a publication document) and a well-based lifting column door-opening type lifting ramp for the integral lifting overpass, so that the superiority and the advancement of the integral flexible adjustment and multifunctional use of the technology are increased.

The technical scheme of the invention comprises the following steps: the two ends of the main span bridge body are provided with conical buckle tooth joints with self-locking inserting fixing bolts which are buckled with the tooth pit hinge movable joint heads, the lower parts of the two buckled joints are provided with folding connection limiting plates, and the tooth pit hinge movable joint heads are connected with the ramp door-opening bridge body in a chained mode to form a bridge deck integral structure. The lifting pier combination portal frame duplex lifting column or the duplex lifting pier arranged below the main span bridge body forms an independent lifting structure of the main span bridge body. The well foundation displacement movable joint lifting column and the well foundation displacement linear lifting column are arranged in the well foundation of the lifting column below the ramp and combined with the portal frame double-connection lifting column or the double-connection lifting pier to form a ramp door-opening type lifting and main span bridge integral lifting structure. And meanwhile, a multifunctional application structure mode that the independent lifting main span bridge body is combined with a fixed ramp is set (the multifunctional application structure mode is used for a wide road surface without lifting the ramp bridge body). The multifunctional lifting flyover mainly has the following functions: the height of the main span bridge foundation can be set in an ultra-low limit mode (based on the passing of buses), the ramp configuration can be greatly shortened through the ultra-low main span bridge, and the short-distance ramp is more beneficial to simple realization of a ramp door-opening type lifting structure while road occupation is reduced. The main span bridge body can reach the national bridge height standard after rising, if the whole rising is taken as keeping the normal state, a ceiling without great obstruction is formed, the normal traffic of the super-high and overweight vehicles at the original road junction is recovered, or the falling is taken as keeping the normal state, and the whole or sectional rising at fixed time or limited time (at night) is taken as a flexible form for regulating the traffic flow.

In a word, the bold advanced innovation idea of the invention changes the traditional solidified bridge into the multifunctional living overpass with higher technical content and wide application, has novel and unique structure, advanced and reasonable technology and obvious use effect, is a breakthrough innovation of the steel-structure overpass technology, is an optimal effective scheme for solving the traffic jam at the road junction, and is an indispensable traffic facility of the future smart city.
