Embodiment 1

[0033] The tubular composite material bridge anti-collision device of the present invention, as Figure 4 (a) shown. The 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, both ends of which are spherical, and the shell 2 is filled with countless PE hollow spheres with a small diameter as the hollow device 12, the shell The space between the body 2 and the hollow device 12 is tightly filled with recycled rubber particles as a buffer energy-dissipating material 11, and then several straight cylindrical anti-collision members 4 made of composite materials are connected in series through the connecting rod 6 to form a horizontal anti-collision body, which is especially suitable for wharf anti-collision Hitting needs to wait.

Embodiment 2

[0035]The tubular composite material bridge anti-collision device of the present invention, as Figure 5 (a) shown. The straight cylindrical anti-collision member 4 is prepared by winding process of glass fiber and unsaturated polyester resin, and the curved cylindrical anti-collision member 5 is prepared by hand lay-up process; both the straight cylindrical anti-collision member 4 and the curved cylindrical anti-collision member 5 are filled with Polystyrene foam mortar is used as a buffer energy-dissipating material 11; the straight cylindrical anti-collision member 4 and the curved cylindrical anti-collision member 5 are connected into a complete rectangular ring device with equal cross-section by using socket flange 7 and bolt 8; Nylon rollers are installed on the contact side of the shaped anti-collision member 4 and the bridge pier as a rolling device 9, and a polytetrafluoroethylene slide plate is installed on the contact side of the socket flange 7 and the bridge pier ...

Embodiment 3

[0037] The tubular composite material bridge anti-collision device of the present invention, as Figure 5 (b) shown. Straight cylindrical anti-collision member 4 is made of glass fiber cloth, emery cloth and unsaturated polyester resin through winding process to form a composite sand-filled pipe, and curved cylindrical anti-collision member 5 is also prepared by winding process; the filling diameter of shell 2 is relatively large 1. Composite winding pipe with both ends closed as hollow device 12, medium coarse sand is tightly filled between hollow device 12 and shell 2 as buffer energy-dissipating material 11, using socket-type flange 7 and bolt 8 to connect the straight tube with variable cross-section The shaped anti-collision member 4 and the curved cylindrical anti-collision member 5 are connected to form a complete rectangular ring structure with variable cross-section.

Abstract

The invention discloses a cylindrical composite bridge anticollision device which comprises an anticollision unit (1), wherein the anticollision unit (1) is composed of a shell (2) and a packing body (3) filled in the shell (2); the anticollision unit (1) comprises straight cylindrical anticollision members (4) and bent cylindrical anticollision members (5); the straight cylindrical anticollision members (4) which are not mutually adjacent are connected in series or in parallel so as to form a strip anticollision device; the straight cylindrical anticollision members (4) which are mutually adjacent and connected, or, one straight cylindrical anticollision member (4) and one bent cylindrical anticollision member (5), or, the bent cylindrical anticollision members (5) are connected by virtue of a socket flange (7) and bolts (8) so as to form a circular or C-shaped anticollision device; and the inside of each straight cylindrical anticollision member (4) is provided with a rolling device (9), and the inside of the socket flange (7) is provided with a slide device (10). The device disclosed by the invention is low in cost, large in elastic deformation and good in anticollision performance.

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, A tubular composite bridge anti-collision device for water (ocean) buildings to reduce ship (floe ice) impact disasters. Background technique [0002] With the rapid development of the transportation industry, the number of large bridges spanning navigable rivers, port areas and straits recently built in my country has gradually increased, and the number of ships on the waterway has also continued to increase and the ship types tend to be large, making the distance between bridges and passing ships The contradiction between the two is becoming more and more prominent, so the accidents of ships colliding with bridge piers are also increasing. Ship collision is one of the main reasons for the collapse of ...
