Description

说明书 筒状复合材料桥梁防撞装置 技术领域  Manual tubular composite bridge anti-collision device
本发明涉及一种桥梁或码头防撞装置,尤其是一种利用复合材料制造的成本低、弹性 大、 耐腐蚀的防撞装置, 具体地说是一种适用于各类桥梁的桥墩以及码头、 水上 (海洋) 建筑如采油平台等用以减轻船舶 (浮冰) 撞击灾害的筒状复合材料桥梁防撞装置。 背景技术  The invention relates to a bridge or dock anti-collision device, in particular to a low cost, high elasticity and corrosion resistant anti-collision device manufactured by using composite material, in particular to a pier and a pier suitable for various bridges, Water (marine) buildings such as oil production platforms and other tubular composite bridge anti-collision devices used to mitigate ship (floe) impact disasters. Background technique
船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。  Ship collisions 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 hit the bridge and lost tens of thousands of yuan. In addition, the casualties and losses are in the millions, tens of millions or even billions of dollars. A large number of indirect losses are even more difficult to calculate.
许多事实表明, 桥梁事故的发生主要是由于桥梁下部结构的破坏, 因此, 需要提高桥 墩的抗撞性能, 具体可以分为两个方面, 即主动抗撞和被动抗撞。主动抗撞是通过桥梁结 构设计来提高桥墩自身的抗撞击能力, 往往需要将桥墩设计的硕大无比, 既不经济美观, 也影响了航道的通航能力; 被动抗撞是通过设置防撞保护系统来提高桥墩的抗撞击能力, 由于其灵活性比较大,可以根据实际情况采用多种方案综合比较,是应用比较广泛的防撞 手段。  Many facts show that the occurrence of bridge accidents is mainly due to the damage of the lower structure of the bridge. Therefore, it is necessary to improve the anti-collision performance of the bridge pier. It can be divided into two aspects, namely active collision and passive collision. Active anti-collision is to improve the anti-collision ability of the pier itself through the design of the bridge structure. It is often necessary to design the bridge pier to be huge, neither economical nor beautiful, but also affect the navigation capacity of the channel. Passive anti-collision is through the installation of anti-collision protection system. Improve the anti-impact ability of the pier, because it is relatively flexible, it can be comprehensively compared according to the actual situation, it is a widely used anti-collision means.
经过多年的研究应用, 国内外出现了多种类型的桥墩防撞设施,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。但目前常用的桩群 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, 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。而钢结构套箱消 能设施利用钢材塑性变形破损消能, 但其通常承受单次撞击, 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, 鉴于目前常用防撞设施 存在的诸多弊端, 本专利拟将纤维增强复合材料结构的耐撞性能引入到桥梁防撞领域中。 发明内容 本发明的目的是针对现有的桥梁防撞装置存在的防撞效果差、成本高、修复难度大等 问题, 提供一种成本低、 弹性大、 耐腐蚀并能充分吸收撞击能量、 延缓撞击时间、 能承受 多次撞击的筒状复合材料桥梁防撞装置。 After years of research and application, various types of pier anti-collision facilities have appeared at home and abroad, but the basic principle is designed based on energy absorption and momentum buffering. Each type of anti-collision facility has its characteristics and conditions of use. However, the commonly used pile group method, thin shell sand coffering method, artificial island method, etc. are generally applicable to occasions with shallow water and good geological conditions. Although once and for all, it will affect the navigation channel, and often because the cost is too high or the condition Give up without giving. The steel structure box energy dissipation facility utilizes the plastic deformation of the steel to break the energy, but it usually bears a single impact. 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 higher. High, in view of the many drawbacks of the current common anti-collision facilities, this patent intends to introduce the crashworthiness of the fiber reinforced composite structure into the field of bridge collision avoidance. Summary of the invention The object of the invention is to provide a low cost, high elasticity, corrosion resistance and sufficient absorption of impact energy and delay of impact time in the existing bridge anti-collision device, such as poor anti-collision effect, high cost and high repair difficulty. A tubular composite bridge anti-collision device capable of withstanding multiple impacts.
