Embodiment 1

[0033] The tubular composite material bridge anti-collision device of the present invention, as figure 1 (a) shown. The cylinder 2 of the anti-collision unit 1 is composed of an outer cylinder 10, an inner cylinder 11 and two layers of intermediate cylinders 12. Each part of the cylinder 2 is made of glass fiber and unsaturated polyester resin. The impact member 4 is prepared by winding process, and the curved cylindrical anti-collision member 5 is prepared by hand lay-up process; polyurethane foam is poured between the outer cylinder 10 and the inner cylinder 11 as a buffer energy-dissipating material 15 between the two, so that the cylinder 2 are bonded as a whole; after the anti-collision device is installed around the pier, ceramsite is filled into the inner cylinder 11 through the filling hole 7 as a buffer energy-dissipating material 15; bolts 8 are used to connect the inner cylinder 11 outside The flange 7 and the flange 7 on the inside of the outer cylinder 10 are bon...

Embodiment 2

[0035] The tubular composite material bridge anti-collision device of the present invention, as figure 1 (b) shown. The cylinder body 2 of the anti-collision unit 1 is composed of an outer cylinder body 10 and an inner cylinder body 11. Each part of the cylinder body 2 is made of glass fiber and vinyl resin. The cylindrical anti-collision member 5 is prepared by cutting and assembling the straight cylindrical anti-collision member 4 according to the angle and then through the hand lay-up process; between the outer cylinder 10 and the inner cylinder 11, coal gangue powder mixed with polyurethane foam material is poured as a buffer energy-dissipating material 15; the inner cylinder 3 is pre-filled with a mixture of sand and ceramsite as a buffer energy-dissipating material 15; bolts 8 are used to connect the flange 7 on the outer side of the inner cylinder 11, and an annular ferrule is set at the joint of the outer cylinder 10 13. Paste the contact between both sides of the fer...

Embodiment 3

[0037] The tubular composite material bridge anti-collision device of the present invention, as Figure 4 (a) shown. The cylinder 2 of the single-layer straight cylindrical anti-collision member 4 is made of basalt fiber cloth and vinyl ester resin through a winding process to form a composite material tube. The hollow ball is used as a hollow device 16, and recycled rubber particles are tightly filled between the outer cylinder body 10 and the hollow device 16 as a buffer energy-dissipating material 15, and then several straight cylindrical anti-collision members 4 made of composite materials are connected in series through connecting rods 6 to form a horizontal Anti-collision body, especially suitable for dock anti-collision needs, etc.

Abstract

The invention discloses a cylindrical composite material bridge anti-collision device which comprises an anti-collision unit (1), wherein the anti-collision unit (1) is composed of a cylindrical body (2) and a filling material body (3) filled in the cylindrical body (2); the anti-collision unit (1) comprises straight cylinder shaped anti-collision members (4) and bended cylinder shaped anti-collision members (5); nonadjacent straight cylinder shaped anti-collision members are connected in series or in parallel through connecting rods (6) to form a strip-shaped anti-collision device; adjacent and mutually connected straight cylinder shaped anti-collision members (4), the straight cylinder shaped anti-collision members (4) and the bended cylinder shaped anti-collision members (5), or the bended cylinder shaped anti-collision members (5) are fixedly connected by adopting bolts (8) through a flange (7) arranged on the cylindrical body (2) to form a cyclic or C-shaped anti-collision structure; and a moving device (9) is arranged at the inner side of the anti-collision unit (1). The cylindrical composite material bridge anti-collision device, disclosed by the invention, has the advantages of a simple structure, low cost, easy installation and maintenance, strong self-floating capability, good buffering performance and low modulus of elasticity.

Description

technical field [0001] The invention relates to a bridge or wharf anti-collision device, especially a low-cost, high-elasticity, corrosion-resistant anti-collision device made of composite materials, specifically a bridge pier and wharf suitable for various types of bridges, Anti-collision devices for bridges made of tubular composite materials used for water (ocean) structures such as oil production platforms to reduce ship (ice floes) impact disasters. Background technique [0002] Ship crashes into bridges have been happening all over the world, and the frequency of ship crashes into bridges 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 casualties, losses in millions, tens of millions or even billions of dollars, and a large number of indirect losses are even more difficult to calculate. [0003] M...
