Fireproof protection system suitable for cable-stayed bridge
The invention provides a fireproof protection system suitable for a cable-stayed bridge. The fireproof protection system comprises a protection sleeve system, a communicating pipeline and a connecting fitting, wherein the protective sleeve system covers the outer part of a cable to be protected, so as to form a'protective coat '; the protective sleeve system is composed of a plurality of protective sleeve units, each protective sleeve unit is of a hollow double-layer structure and is a closed cavity, water or other appropriate fluid is injected into a space defined by the inner wall and the outer wall of a protective sleeve body, the protective sleeves are mutually connected through communicating pipelines on the lower portions, and the fluid flows among the different protective sleeves. According to the invention, the temperature of the steel cable can be always kept at a relatively low level by utilizing the physical characteristics of water; the principle of communicating vessels is fully utilized, and it is guaranteed that water sources at all positions can flow mutually and automatically flow to needed positions; durability is good, daily maintenance is little, and the automatic working capacity is high; installation is flexible, the shape is customized according to a specific bridge, and steel cables of different bridges can be well attached.
本发明提供了一种适用于拉索桥的防火保护系统，包括保护套筒系统、连通管道和连接配件；其中，保护套筒系统包覆在待保护的缆索外部，形成“保护外衣”；保护套筒系统，由众多的保护套筒单元构成，各个保护套筒单元为中空双层构造，为密闭腔体，保护套筒主体内外壁围成的空间内注入水或其他合适的流体，各保护套筒通过下部的连通管道相互连接，流体在不同保护套筒间流动。本发明利用水的物理特性，能将钢索温度始终保持在一个相对较低的水平；并充分利用了连通器的原理，保证各处的水源能够相互流动并自动流向需要的位置；耐久性好，日常维护少，自动化工作能力强；安装灵活，且形状根据具体桥梁定制，能够很好的贴合不同桥梁的钢索。
