Embodiment 1

[0033] Such as Figure 6 As shown, a honeycomb lattice-reinforced double-tube structure of composite material, the double-tube structure is composed of 4 straight tube units 5 with equal cross-section and 4 curved tube units 6, and mortise and tenon joints are used between the straight tube units 5 and curved tube units 6 The joint 7 and the latch rod 17 are connected as a whole and arranged around the bridge tower column. In order to realize the anti-collision system floating with the water level, a polytetrafluoroethylene plate is installed between the anti-collision system and the pier as a mobile device 8 . The straight cylinder unit 5 and the curved cylinder unit 6 are mainly composed of an outer cylinder 1, an inner cylinder 2, a honeycomb lattice reinforcement 3 woven between the inner cylinder 1 and the outer cylinder 2, and a filling material body 4 filled in the inner cylinder 2. During specific molding, glass fibers are laid in the mold, and the polyurethane foam w...

Embodiment 2

[0035] Such as Figure 7 As shown, a honeycomb lattice-reinforced double-tube structure of composite material, the anti-collision structure is composed of 6 straight tube units 5 with equal cross-section, 4 straight tube units 5 with variable cross-section and 8 curved tube units 6, and the adjacent straight tube units 5 Between them or between the straight cylinder unit 5 and the curved cylinder unit 6, they are connected as a whole by mortise and tenon joints 7 and latch rods 17, and are arranged around the bridge cap. In order to realize the anti-collision system floating with the water level, a honeycomb lattice reinforced column is installed between the anti-collision system and the bridge pier as a mobile device 8, and the honeycomb lattice reinforced column is formed by vacuum introduction of glass fiber and paulownia wood. Considering the different risks of ship collision on each side of the pier, a large-diameter double-tube structure is set on the collision side, and...

Embodiment 3

[0037] Such as Figure 8 As shown, a honeycomb lattice-reinforced double-tube structure of composite material, the anti-collision structure is composed of 10 straight tube units 5 of equal cross-section and 6 curved tube units 6, between adjacent straight tube units 5 or straight tube units 5 and curved tube units The cylinder units 6 are connected as a whole by mortise and tenon joints 7 and latch rods 17, and are arranged around the bridge pier body. In order to realize the anti-collision system floating with the water level, a plastic slide plate is installed between the anti-collision system and the pier as the mobile device 8 . In order to effectively shift away from the ship's driving direction, the anti-collision section on the collision side is set as a sharp point, so as to ensure that the ship will not directly hit the pier. The straight cylinder unit 5 and the curved cylinder unit 6 are mainly composed of an outer cylinder 1, an inner cylinder 2, a honeycomb lattic...

Abstract

The invention discloses a honeycomb lattice enhanced type composite material double-cylinder structure and an anti-collision system using the same. The double-cylinder structure comprises an outer cylinder (1) and an inner cylinder (2), wherein a honeycomb lattice enhanced body (3) is arranged between the outer cylinder (1) and the inner cylinder (2); and a filling material body (4) is filled into the inner cylinder (2). The anti-collision system comprises the honeycomb lattice enhanced type composite material double-cylinder structure, wherein the double-cylinder structure comprises straight cylinder units (5) and bent cylinder units (6); adjacent and mutually connected straight cylinder units (5), the straight cylinder units (5) and the bent cylinder units (6), or the bent cylinder units (6) are connected together through mortise and tenon joints (7) and bolts bars (16) so as to form a strip-shaped or annual anti-collision system; and a moving device (8) is arranged on the inner side of the anti-collision system. The double-cylinder structure is integrally formed in a weaving mode, and the filling material body has higher rigidity, so that the deformation degree can be limited without crack, and the double-cylinder structure is long in service life, low in cost and easy to maintain.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to an anti-collision facility applicable to various types of bridge piers, wharves, water structures, ocean platforms, etc. to reduce the impact disasters of ships, vehicles, and ice floes, and a light-weight and high-strength vertical structure. Specifically, it is a honeycomb lattice-reinforced composite double-tube structure with strong designability, low cost and corrosion resistance made of composite materials and an anti-collision system using it. 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 m...
