Bridge floor anti-wave anti-collision guardrail for sea-crossing bridge

Abstract

The invention provides a bridge floor anti-wave anti-collision guardrail for a sea-crossing bridge. The bridge floor anti-wave anti-collision guardrail for the sea-crossing bridge comprises vertical column bases, vertical columns, upper cross beams, anti-collision cross beams, anti-wave baffle plate bases and anti-wave baffle plates. The column bases and the anti-wave baffle plate bases are installed in a curb of the bridge floor for fixing the bottom portions of the vertical columns and the anti-wave baffle plates. The vertical columns are vertically arranged on the top of the vertical columnbases. Opposite column surfaces, in the bridge direction, of the vertical columns are provided with first connecting pieces. The column surfaces, facing to the side of a vehicle, of transverse bridges, are provided with second connecting pieces. The upper cross beams are fixed between the vertical columns by the first connecting pieces. The anti-collision cross beams are vertically fixed on the vertical columns by the second connecting pieces. The anti-wave baffle plates are fixedly embedded between the vertical columns, the upper cross beams and the anti-wave baffle plate bases, Z-shape-distributed optical fiber sensors are arranged in interlayers of the anti-wave baffle plates, and ''water drop '' shape damping and energy dissipation cushions are arranged on the circumferential circlesof the anti-wave baffle plates. According to the bridge floor anti-wave anti-collision guardrail for the sea-crossing bridge, the water resistance and collision avoidance are achieved at the same time, and the wave force of the overtopping waves can be tested; the landscape effect is good, the effects of damping and energy dissipation are good, the durability is good, and the driving environment of the bridge floor can be significantly improved.

Description

technical field [0001] The invention relates to the technical field of sea-crossing bridge engineering, in particular to a bridge deck anti-wave and anti-collision guardrail of a sea-crossing bridge. Background technique [0002] The process of global regional economic integration has prompted countries all over the world to accelerate the planning and research of more ambitious cross-sea channel projects. Looking forward to the future, there is a huge demand for the construction of super-large cross-sea bridges. For example, cross-sea channel projects across the Qiongzhou Strait, Bohai Strait, Sunda Strait, and Gibraltar Strait are being planned and studied. Sea-crossing bridge projects are faced with challenges in marine environments such as deep water, strong winds, and huge waves. For the island-bridge joints of sea-crossing bridge projects and other parts of the bridge deck with low design elevations, there are hidden dangers of waves on the bridge deck. Driving safety...
