Water area bridge flexible anti-collision wall and construction method thereof

Abstract

The invention relates to a water area bridge flexible anti-collision wall which comprises a steel plate pile cofferdam, a pier bearing platform, a support, a concrete bottoming, expansion bolts, a light high-strength filler, anti-collision steel structures and anti-collision marks; the anti-collision steel structures, each of which is mainly formed by a single frame, a coupling beam and an anti-collision ring beam, are fixed at the periphery of the pier bearing platform; the single frames are fixed on the pier bearing platform through the expansion bolts respectively; the anti-collision ring beams are fixed on the outer side of the single frames respectively; and the adjacent single frames, each of which is formed by a connecting plate, a cross rod, a vertical rod, an intermediate inclinedrod and a bottom inclined rod, are connected through the corresponding coupling beam. The water area bridge flexible anti-collision wall has the beneficial effects that the water area bridge flexibleanti-collision wall is suitable for construction of anti-collision walls of pier bearing platforms in the rivers, lakes and sea and is formed by the steel plate pile cofferdam, the anti-collision steel structures and the light high-strength filler; and in addition, with arrangement of the steel plate pile cofferdam, a temporary support and auxiliary trestles are not required to be temporarily erected around a pier, an additional construction loading is not caused to bearing stress of the pier, and the technical benefit is obvious.

Description

technical field [0001] The invention relates to a flexible anti-collision wall, in particular to a flexible anti-collision wall for a bridge in a water area navigable environment and a construction method thereof. Background technique [0002] With the rapid development of the national economy, more and more long-span bridges are being built in rivers, lakes and seas; for the protection of pier caps when bridges are open to navigation, integral anti-collision steel casings are usually used. The lowering of the steel box is conventionally carried out with a large floating crane, and the construction cost is high, and the larger the tonnage of the anti-collision steel box, the larger the large floating crane ship required, which will further increase the cost. [0003] During the construction of the traditional anti-collision steel box, the support system and auxiliary trestle need to be built around the pier cap in advance, which will not only increase the construction cost, ...

AI Technical Summary

Problems solved by technology

[0007] The present invention mainly aims at the problems of high construction cost and large construction load in the construction of the anti-collision wall, and provides a flexible anti-collision wall for bridges in water areas and its construction method, which can reduce the self-weight of the anti-collision wall and reduce the excessive impact on the bridge pier cap. Large load or negative friction resistance, while achieving recycling of building materials, reducing construction difficulty, achieving technological progress, and realizing cost advantages
