Construction method of semi-sunken self-balancing fusiform double-arch fabricated overpass

Abstract

The invention discloses a construction method of a semi-sunken self-balancing fusiform double-arch fabricated overpass, which belongs to the technical field of roads and bridges, and is arranged at a crossroad. The method comprises the following steps that A, site preparation is performed; B, the lower arch prefabricated parts are hoisted to the designated position, and then the lower arch prefabricated parts are connected to form a second arch bridge; C, the supporting column is hoisted to the designated position and connected with the lower arch prefabricated part; and D, the upper arch prefabricated part is hoisted to a designated position, then the upper arch prefabricated part is connected with the supporting columns to form a first arch bridge, and the prefabricated parts at the two ends of the first arch bridge and the second arch bridge are connected through mortise and tenon joint structures. By adopting a double-arch form, passing of vehicles and pedestrians in all directions cannot be affected at the crossroad, an existing traffic light system can be omitted, and rapid passing of the vehicles and the pedestrians is achieved; and the second arch bridge is a sunken structure, the first arch bridge can be prevented from being too high, the bridge floor is prefabricated in a factory and installed on site, and rapid construction can be achieved.

Description

technical field [0001] The invention belongs to the technical field of roads and bridges, and in particular relates to a construction method for a semi-submerged self-balancing shuttle-shaped double-arch assembled overpass. Background technique [0002] With the rapid development of the city, more and more people flow into the city, and with the continuous improvement of people's living standards, the number of cars is also increasing rapidly, which will bring great pressure to urban traffic. Pass through the streets, and the vehicles can drive in an orderly manner. Most of the traffic lights in modern cities are managed by traffic lights. Generally speaking, the traffic lights play a very good role in helping the orderly driving of vehicles. When encountering a large traffic flow, if the timing of the alternation of traffic lights is not well grasped, it will not help the driving of vehicles much, and it will still cause congestion. [0003] The invention patent with the a...

Problems solved by technology

[0002] With the rapid development of the city, more and more people flow into the city, and with the continuous improvement of people's living standards, the number of cars is also increasing rapidly, which will bring great pressure to urban traffic. Through the streets, and vehicles can drive in an orderly manner, most of the modern urban traffic relies on traffic lights to achieve management. Generally speaking, traffic lights play a very good role in helping vehicles drive in an orderly manner. When encountering a large traffic flow, if the timing of the alternation of traffic lights is not well grasped, it will not help the driving of vehicles much, and it will still cause congestion

[0003] The invention patent with the application number 201520037027.8 discloses a cross-street bridge and a double-arch bridge at a crossroad. Bicycles and pedestrians use the pedestrian bridge hole to quickly pass through the street in parallel. There is no intersection, but when it is applied to the intersection of traffic lights that are prone to congestion, the structure of the overpass will be complicated, the cost will be high, and the practicability will be poor
