【摘要】：近年來,由于人口數(shù)量的增加和用地的限制,逐漸地出現(xiàn)了道路立體化即多條線路立體交叉,那么城市道路的立體化必然是未來的發(fā)展趨勢(shì)。橋梁轉(zhuǎn)體施工就是在跨過既有線、山谷、河流的一個(gè)很好的應(yīng)用。橋梁轉(zhuǎn)體施工有平轉(zhuǎn)法和豎轉(zhuǎn)法,經(jīng)過多年的發(fā)展,這兩種方法已經(jīng)發(fā)展的相當(dāng)成熟。修建跨過既有線的橋梁,在不影響既有線路的情況下,橋梁轉(zhuǎn)體施工無疑是最好的方法。然而,交通干線工況復(fù)雜,往往不具備線下拼裝條件,且對(duì)配重有較高的要求,因此,復(fù)雜工況下的高位拼裝成了廣大研究者需要解決的難題。本文以春申特大橋跨越滬昆鐵路的簡(jiǎn)支梁轉(zhuǎn)體施工為工程背景,全面的介紹了橋梁轉(zhuǎn)體施工的準(zhǔn)備工作、施工工藝流程以及在施工過程中的一些驗(yàn)算。滬昆鐵路是電氣化鐵路,要想把對(duì)其影響的程度降到最低,所遇到的技術(shù)難題可想而知,在研究探討了本次轉(zhuǎn)體施工過程中所遇到的技術(shù)難題后,根據(jù)現(xiàn)場(chǎng)的條件,我們制定出了高位拼裝、無平衡重轉(zhuǎn)體的方案,這是本工程的亮點(diǎn)。在施工過程中轉(zhuǎn)動(dòng)裝置做了改進(jìn),并且設(shè)計(jì)了走行滑道梁,最后對(duì)本次轉(zhuǎn)體施工進(jìn)行了總結(jié)。
[Abstract]:In recent years, due to the increase of population and the limitation of land use, the three-dimensional road is gradually appeared, that is, the intersection of many lines, so the three-dimensional road of the city is bound to be the development trend in the future. Bridge turnaround construction is a good application across existing lines, valleys, and rivers. There are horizontal and vertical methods for bridge rotation construction. After years of development, these two methods have been developed quite mature. It is the best way to build the bridge over the existing line without affecting the existing line. However, the traffic trunk is complex in working condition, it often does not have the offline assembling condition, and has the higher requirement to the counterweight, therefore, the high position assembly under the complex working condition has become the difficult problem which the majority of researchers need to solve. Based on the engineering background of simply supported beam rotation construction of Chunshen Super Bridge across the Shanghai-Kunming Railway, this paper comprehensively introduces the preparation work, construction technological process and some checking calculation in the construction process. The Hu-Kun Railway is an electrified railway. If we want to minimize the impact on it, we can imagine the technical difficulties encountered. After studying and discussing the technical difficulties encountered in the course of this rotary construction, according to the conditions of the site, We have worked out a high-level assembly, non-balanced weight of the program, which is the highlight of the project. In the process of construction, the rotary device is improved, and the sliding beam is designed. Finally, the author summarizes the rotary construction.
