Problems solved by technology

The swivel method requires a large construction site and an open space. During construction, buildings within the radius of rotation need to be demolished. At the same time, all engineering loads are concentrated on one spherical fulcrum during the swivel process. The overall stability of the project is poor and risks high
The jacking method is more suitable for steel structures with variable cross-section beams, but it is difficult to adapt to variable cross-section prestressed reinforced concrete beams.

Embodiment Construction

[0031] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0032] Such as Figure 1 to Figure 5 As shown, a bridge with double piers joint foundation and variable cross-section girders is moved and closed synchronously. The skateboard foundation 1 on the top, the push back beam 4 arranged on the push side of the skateboard foundation 1, the sliding layer 2 arranged on the skateboard foundation 1, and the pier beam layer arranged on the sliding layer 2;

[0033] The pile base includes pier bored piles 7, a temporary pipe pile foundation 3 arranged between the bridge pier bored piles 7 for foundation reinforcement, and a slide base 1 is arranged on the temporary pipe pile foundation 3 and the pier bored piles 7. A prestressed steel strand bundle 6 is arranged in the foundation 1 and the back beam 4 for pushing;

[0034] The pier beam layer includes a joint foundation and a variable cross-section beam body 11. T...

Abstract

The invention discloses an overpass bridge design construction method applicable to incremental launching method construction and belongs to the technical field of variable cross-section girder body design construction. Main construction operation can be away from a spanned space, it is guaranteed that an existing railway, highway or city road is not interfered by construction, and underbridge safety is ensured, and the overpass bridge design construction method is an alternative scheme when rotation construction is not suitable. The design construction method comprises the steps that temporary tubular pile foundation treatment is conducted, and sliding plate foundations, sliding layers and incremental launching back girders jointed with bridge pier foundations enable a jointed foundation composed of foundation connection girders, bridge bearing table foundations and bridge girders to drive a variable cross-section girder body to conduct simultaneous incremental launching to further achieve being folded with an overline on the other side. The method is suitable for an overpass bridge which spans the railway, the highway or the city road and located in a narrow site with dense city buildings and without rotation construction conditions.

Description

technical field [0001] The invention relates to a method for designing and constructing a flyover bridge suitable for construction by the jacking method, and belongs to the technical field of design and construction of beams with variable cross-sections. Background technique [0002] In the construction of reinforced concrete continuous beams across railways, highways or urban roads, in order to reduce the interference and influence on the spanning space of variable cross-section beams and ensure the safety of driving on existing railways, highways or urban roads, the hanging basket method was generally used in the past Sectional cantilevered concrete. With the improvement of safety awareness, currently more secure methods of turning and pushing are adopted, but both methods have limitations. The swivel method requires a large construction site and an open space. During construction, buildings within the radius of rotation need to be demolished. At the same time, all engine...
