【摘要】：隨著人民群眾對鐵路運(yùn)輸“高速度、高舒適性、高安全性”的要求不斷提高,鐵路橋梁特別是大跨度橋梁的保養(yǎng)及維護(hù)難度也在不斷增大。為打造養(yǎng)護(hù)一大批精品橋梁,實(shí)現(xiàn)“一流的技術(shù)標(biāo)準(zhǔn)、一流的設(shè)備質(zhì)量、一流的管理水平、一流的隊伍素質(zhì)、一流的生產(chǎn)環(huán)境”等目標(biāo),需要我們對橋梁日常養(yǎng)護(hù)保養(yǎng)體系進(jìn)行不斷的探索和研究。天興洲大橋是我國第一座四線鐵路公鐵兩用斜拉橋,橋梁上使用的多項(xiàng)關(guān)鍵技術(shù)設(shè)備達(dá)到世界先進(jìn)水平。本文以該橋?yàn)楣こ瘫尘?首先介紹了天興洲長江大橋的基本情況和設(shè)計參數(shù),研究探討了大橋日常管理養(yǎng)護(hù)維修的方案,重點(diǎn)介紹了天興洲大橋上裝備的ZLA-1040大位移梁端伸縮裝置、滑板式鉸軸支座、400kN磁流變液阻尼器系統(tǒng)、鋼軌伸縮調(diào)節(jié)器及橋梁斜拉索體系等多項(xiàng)新技術(shù)設(shè)備的工作原理和正常工作狀態(tài)、易損情況,探討了這些設(shè)備的日常養(yǎng)護(hù)規(guī)則及要求,在此基礎(chǔ)上形成了高速鐵路線上大跨度公鐵兩用斜拉橋養(yǎng)護(hù)維修體系。
[Abstract]:With the requirement of "high speed, high comfort and high safety" for railway transportation, the maintenance and maintenance of railway bridges, especially long-span bridges, is becoming more and more difficult. In order to build a large number of excellent bridges and achieve the goals of "first-class technical standard, first-class equipment quality, first-class management level, first-class team quality, first-class production environment" and so on, Need us to the bridge daily maintenance system for continuous exploration and research. Tianxingzhou Bridge is the first four-line railway and road-rail cable-stayed bridge in China. Many key technical equipments used on the bridge reach the advanced level in the world. Taking the bridge as the engineering background, this paper first introduces the basic situation and design parameters of Tianxingzhou Yangtze River Bridge, and studies and discusses the scheme of daily maintenance and maintenance of the bridge. The paper mainly introduces the ZLA-1040 large displacement beam end telescopic device and the 400kN magnetorheological fluid damper system on the Tianxingzhou Bridge. The working principle, normal working state and vulnerability of many new technical equipments, such as rail expansion regulator and bridge cable system, are discussed. The daily maintenance rules and requirements of these equipment are discussed. On this basis, the maintenance and repair system of long span highway-iron cable-stayed bridge on high-speed railway line is formed.
