Problems solved by technology

[0005] The purpose of the present invention is to design a bridge cap anti-collision buffer bag with better elasticity and energy dissipation capacity for the existing bridge cap anti-collision device, which is complex in structure, high in cost and unable to effectively protect ships. The anti-collision buffer bag is connected in series and installed around the bridge cap to achieve effective protection, which can protect the cap from damage and effectively protect the ship from damage

example 1

[0031] In the anti-collision buffer bag for bridge caps of the present invention, the outer diameter of the glass fiber / unsaturated polyester resin composite circular tube 1 formed by winding is 0.6m, the wall thickness is 0.02m, and the length is 5m, and the circular tube is tightly filled and vertically arranged. The moso bamboo 2 is made of composite material circular tubes as the axis, and the rubber tires are stacked sequentially. There is no filling inside the tires to form a 5m-high tire buffer column. Teflon canvas is placed on the periphery of the tire column to form a buffer bag. Fix the buffer bags at intervals around the pier caps.

example 2

[0033] In the bridge cap anti-collision buffer bag of the present invention, the outer diameter of the basalt fiber / vinyl resin composite material circular tube 1 formed by pultrusion is 0.5m, the wall thickness is 0.01m, and the length is 6m, and the polyurethane foam 2 is filled in the circular tube. Composite material round tubes are used as shafts, and rubber tires are stacked sequentially. The interior of the tires is filled with thin water bamboos bent in the circumferential direction to form a 6m-high tire buffer column. PVC canvas is placed on the periphery of the tire column to form a buffer bag. The line secures the cushion bag to the shore of the dock.

example 3

[0035] In the bridge cap anti-collision buffer bag of the present invention, the outer diameter of the carbon fiber / epoxy resin composite circular tube 1 formed by winding is 0.3m, the wall thickness is 0.005m, and the length is 3m, and the circular tube is filled with foamed aluminum 2. The round tube is used as the axis, and the rubber tires are stacked in sequence. The tires are filled with polyurethane foam to form a 3m-high tire buffer column. The PVDF canvas is placed around the tire column to form a buffer bag, and the buffer bag is fixed in the ocean with steel strands. Around the oil production platform.

[0036] The manufacture method of anti-collision buffer bag of the present invention is:

[0037] a. Prepare a set of cylindrical steel moulds. After determining the parameters such as winding angle, wall thickness, length, and diameter according to the force calculation, prepare glass fiber / vinyl resin composite material round pipe 1 by winding process on the steel ...

Abstract

An anti-collision cushioning bag for a bridge bearing platform is characterized in that it includes a round tube shaft (6), an automobile outer tire (3) and a canvas bag (4), and the round tube shaft (6) is made of a composite material round tube ( 1) and filling material (2), the outer car tires (3) are sequentially set and laminated on the circular tube shaft (6), and the inside of each car outer tire (3) is filled with elastic material filler, and the round tube shaft (6) and automobile outer tire (3) are all set in the canvas bag (4). The invention can effectively prolong the impact time, reduce part of the impact force, protect the concrete pier cap from local damage, and effectively protect ships.

Description

[0001] The invention applied for a utility model patent on the same day. technical field [0002] The invention relates to an anti-collision product for a bridge cap, especially a bridge cap anti-collision product mainly made of green recycled materials, specifically a bridge cap that can be connected in series and installed around the bridge cap Anti-collision buffer bag. Background technique [0003] As we all know, the caps of bridges generally meet the anti-collision requirements in structural design, but at low navigable water levels, in order to protect ships, especially when the underwater spherical head collides with the caps, due to the steel plate and concrete bearing Taiwan is a "head-to-head", and ships are prone to serious damage. At present, steel structure casings are mostly used around the caps, such as: Hangzhou Bay Bridge. When a ship hits the anti-collision device of the steel casing, the outer structural steel plate of the anti-collision structure underg...
