Structure capable of realizing large-span V-shaped pier continuous rigid frame bridge and construction process thereof

Abstract

The invention discloses a structure capable of realizing a large-span V-shaped pier continuous rigid frame bridge. The structure at least comprises a beam body and a pier bottom bearing platform, wherein the beam body can be supported on the pier bottom bearing platform by a V-shaped pier bottom connection structure; the V-shaped pier bottom connection structure comprises a temporary longitudinal sliding support arranged between the beam body and the pier bottom bearing platform, and also comprises a pier bottom post-poured consolidation groove structure arranged on the pier bottom bearing platform and a pushing back structure arranged on the pier bottom bearing platform; and an opposite vertex device is arranged between the temporary longitudinal sliding support and the pushing back structure. The invention also discloses a construction process of the structure. By adopting the V-shaped pier bottom connection structure and the slidable variable solidification technical measure, the structure disclosed by the invention can realize the system transformation from the continuous beam change rigid frame in the stage of beam body closure, the structure is simple and convenient for construction, the harmful secondary interior force, of the V-shaped pier continuous rigid frame bridge, generated in the closure stage can be effectively solved, so that the span of the V-shaped pier continuous rigid frame bridge can break through the limit in the prior art, and the consumption of the midspan steel beam for closure can be reduced.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a construction technique for realizing the construction of a continuous rigid-frame bridge with V-shaped piers with a large span. Background technique [0002] Continuous rigid frame bridge with V-shaped piers is a hybrid structural system composed of multi-span continuous beams and rigid frames, which has the mechanical characteristics of both rigid frames and continuous beams. Since the oblique legs of the V-shaped piers reduce the span of the main beam to a certain extent, the peak values ​​of the maximum positive and negative bending moments of the main beam are significantly reduced, so that the building height of the beam can be significantly reduced, and the entire hybrid structure system has structural rigidity. Large, good overall advantages. [0003] However, if figure 1 As shown, when the span of a continuous rigid frame bridge with V-shaped piers is large, si...

Problems solved by technology

However, the V-shaped pier continuous rigid frame bridge with hanging holes not only adds a set of hanging hole construction facilities during construction, but also increases the expansion joints in the two main spans, which affects the structural integrity of the V-shaped pier continuous rigid frame bridge. , shock resistance are unfavorable, driving comfort is also reduced
