Abstract

The invention relates to a self-floating composite material bridge pressurized-water anti-collision device. The anti-collision device is characterized by comprising a shell part (12) and a water-spraying energy-consumption part (13), wherein the water-spraying energy-consumption part (13) is arranged by clinging to the bridge; the shell part (12) is arranged outside the water-spraying energy-consumption part (13); the shell part (12) consists of a composite material surface layer (1), a sandwich material layer (2) and a filling material body (3); the sandwich material layer (2) is clamped in the composite material surface layer (1) and forms a shell wall (14); the filling material body (3) is filled in space formed by the shell wall (14); the water-spraying energy-consumption part (13) consists of a canvas water bag (6) filled with water (10), a circle of transverse frameworks (8) which is arranged at a regular interval along the transverse direction of the canvas water bag (6) and longitudinal framework (9) which is arranged along the longitudinal direction of the water bag; the canvas water bag (6) is provided with draining holes (7) regularly; and the shell part (12) is also provided with a rail (11). The anti-collision device has the advantages of simple structure, convenient manufacture, installation and maintenance, low cost and environmental protection.

Description

[0001] The utility model patent was applied for on the same day as the invention date. technical field [0002] The invention relates to a bridge anti-collision device, in particular to a composite material bridge pressure-water anti-collision device with high strength, good energy consumption, corrosion resistance, self-floating and made of green environmental protection materials, specifically an applicable It is a self-floating composite material bridge pressure water anti-collision device for piers of various bridges, wharves, and water (ocean) buildings to reduce ship (floe ice) impact disasters. Background technique [0003] As we all know, ship collision accidents have been happening all over the world, and the frequency of ship collision accidents is much higher than we imagined. The loss of life, property damage, and environmental damage caused by ship-bridge accidents is staggering. Many ship collision accidents range from losses of tens of thousands of yuan to ca...
