Abstract

The invention relates to an energy-dissipating and collision-preventing combined device of a floating composite pier, which is characterized by at least comprising an internal layer corrosion-preventing ring (16) arranged along the pier, wherein the internal layer corrosion-preventing ring (16) comprises a plurality of composite lattice pouring jackets (17) arranged around the pier, the composite lattice pouring jackets (17) are connected to form an integrated structure through longitudinal composite presstressed reinforcing steels (6) and transverse composite presstressed reinforcing steels (7), the side of each composite lattice pouring jacket (17) is provided with an anchor head (10), the upper surface and the lower surface of each composite lattice pouring jacket (17) are both embedded with embedding pieces (11) connected with the adjacent composite lattice pouring jackets (17); part or all of the composite lattice pouring jackets (17) forming the internal layer corrosion-avoiding ring (16) are connected with pulleys (13); the joint of the adjacent composite lattice pouring jackets (17) is provided with a sealing body; and one surface of each composite lattice pouring jacket (17) contacting with water is provided with a wave-dissipating hole (15). Compared with the traditional steel pouring jacket, the invention has better shock resistance and durability, light weight, and convenient installation and repair, can save materials, and shorten the construction period.

Description

technical field [0001] The invention relates to an infrastructure, especially a protective structure of bridges in water, in particular to a floating composite material pier energy dissipation and anti-collision combination device. Background technique [0002] As we all know, with the continuous development of transportation, a large number of bridges across the sea and across the river are constantly being built. For bridges spanning waterways, it is inevitable to bear the risk of ship collision. Such incidents often cause loss of bridge structure, service life, safety and earthquake resistance, and even cause catastrophic consequences such as bridge destruction and death. The cost of rebuilding bridges and dredging waterways is also very alarming. The existing anti-collision devices for navigable bridges mostly use steel casings on the periphery of the bridge piers. The main function of the anti-collision steel casings is to dissipate energy when the facilities are damag...
