Description
说明书 一种缓冲吸能型腹板增强复合材料防撞装置 技术领域 Description: A buffering energy absorption type web reinforced composite material anti-collision device
本发明涉及一种桥梁或码头防撞结构,尤其是一种利用复合材料制造的低成本绿色防 撞装置, 具体地说是一种适用于各类桥梁的桥墩、 桥塔、 承台、 码头、 水上建筑、 海洋建 筑以及航船用以减轻船舶、浮冰或车辆等撞击灾害的缓冲吸能型腹板增强复合材料防撞装 置。 背景技术 The invention relates to a bridge or dock anti-collision structure, in particular to a low-cost green anti-collision device manufactured by using composite materials, in particular to a pier, a pylon, a cap, a pier, and the like, which are suitable for various bridges. Water-absorbing buildings, marine buildings, and cushioning energy-absorbing web reinforced composite anti-collision devices for reducing impact damage such as ships, ice floes or vehicles. Background technique
众所周知, 船(车)撞桥事故在世界各地一直在不断地发生, 船撞桥事故的频率远比 我们想象的更高。 由船撞桥事故所导致的人员伤亡、财产损失以及环境破坏是惊人的。很 多船撞桥事故轻则损失数万元,重则人员伤亡、损失以数百万、数千万甚至数十亿美元计, 大量的间接损失更是难以计算。 因此对桥梁采取防撞措施尤为必要, 其根本目的是: 防止 桥梁因船舶 (车辆) 撞击力而发生结构毁坏, 同时尽可能地保护船舶 (车辆), 将损失减 小到最低程度。 As we all know, ship (vehicle) bridge accidents have been happening all over the world, and the frequency of ship collisions is much higher than we think. The casualties, property damage and environmental damage caused by the ship’s collision with the bridge were amazing. Many ships have lost tens of thousands of yuan in accidents, and heavy casualties and losses are in the form of millions, tens of millions or even billions of dollars. A large number of indirect losses are even more difficult to calculate. Therefore, it is especially necessary to take anti-collision measures for the bridge. The basic purpose is to prevent the bridge from being damaged due to the impact of the ship (vehicle) and to protect the ship (vehicle) as much as possible to minimize the loss.
经过多年的研究应用, 国内外出现了多种针对船桥碰撞的桥墩防撞设施,但其基本原 理是基于能量吸收、动量缓冲而设计的, 每种防撞设施都有其特点和使用条件。具体来说 防撞设施可分为两大类: 一为间接式, 其特点为: 在桥墩之外另设防撞设施, 桥墩不直接 受力, 让桥墩彻底回避船舶撞击的问题。 如: 桩群方式、 薄壳筑沙围堰方式、 人工岛方式 等, 一般适用于水浅、地质情况较好的场合。 间接式防撞方法虽然一劳永逸, 但会影响航 道, 且常常因为造价太高或者条件不具备而放弃。 二为直接式, 其特点为: 力经过缓冲后 直接作用在桥墩上, 如护弦方式、绳索变形方式、 缓冲材料设施方式、 缓冲设施工程方式 及固定或浮式套箱防撞设施等。一般使用在航道较窄、水较深的场合,通常建造费用较省, 土建工程量不大。如: 珠江特大桥、 上海长江大桥采用钢箱型防撞装置, 该消能设施利用 钢材塑性变形破损消能, 当船舶撞击钢套箱防撞装置时, 防撞结构外层非连续 (间断的) 结构钢板发生大的变形, 吸收了部分碰撞能量, 并且延长了接触时间, 使撞击力峰值得以 降低, 同时由于结构变形和相互作用, 从而拨动船头方向, 减少了船舶与结构间的能量交
换。但钢套箱通常承受单次撞击, 撞损后维修较困难; 同时碰撞时船体易受损伤; 另外钢 材常年在水中易锈蚀, 维护费用较高, 故采用新材料设计开发新型防撞系统迫在眉睫。 发明内容 After years of research and application, various anti-collision facilities for bridge pier collisions have appeared at home and abroad, but the basic principle is designed based on energy absorption and momentum buffering. Each type of anti-collision facilities has its characteristics and conditions of use. Specifically, anti-collision facilities can be divided into two categories: one is indirect, and its characteristics are: There is another anti-collision facility outside the pier, the pier is not directly stressed, so that the pier completely avoids the problem of ship impact. Such as: pile group method, thin shell sand reclamation method, artificial island method, etc., generally suitable for occasions with shallow water and good geological conditions. The indirect collision avoidance method, once and for all, affects the navigation channel and is often abandoned because the cost is too high or the conditions are not. The second is direct type, which is characterized by: The force acts directly on the pier after buffering, such as the string protection mode, the rope deformation mode, the buffer material installation mode, the buffer facility engineering mode and the fixed or floating box anti-collision facilities. Generally used in places where the channel is narrow and the water is deep, the construction cost is usually less, and the amount of civil works is not large. Such as: Zhujiang Bridge and Shanghai Yangtze River Bridge adopt steel box type anti-collision device. The energy dissipating facility uses plastic deformation of steel to break and dissipate energy. When the ship hits the steel box anti-collision device, the outer layer of the anti-collision structure is discontinuous (intermittent The structural steel plate undergoes large deformation, absorbs part of the collision energy, and prolongs the contact time, which reduces the peak impact force. At the same time, due to structural deformation and interaction, the direction of the bow is shifted, and the energy between the ship and the structure is reduced. Pay Change. However, the steel box usually bears a single impact, and it is difficult to repair after the damage. At the same time, the hull is vulnerable to damage during the collision. In addition, the steel is easy to rust in water all year round, and the maintenance cost is high. Therefore, it is extremely urgent to design and develop a new collision avoidance system with new materials. Summary of the invention
