北京南站工程综合施工新技术

北京南站工程是集国有铁路、地铁、市郊铁路和公交、出租汽车等市政交通设施为一体的大型综合交通枢纽,也是我国建成通车的第一条高速铁路始发车站。施工中克服了工程体量庞大,工期紧,站房地下结构形式复杂独特,钢结构安装难度大等难点,采用了大直径旋挖钻孔灌注桩技术、轨道层高支模技术、大体积混凝土技术、钢管自密实混凝土技术、轨道层动荷载下钢筋连接技术、空间钢结构安装技术、既有线安全施工防护、群塔作业防碰撞技术、绿色新能源等应用技术。"北京南站综合技术成果"通过专家组鉴定,该课题整体施工技术达到国内领先水平,其中大跨度空间钢结构施工技术达到国际先进水平。

NEW INTEGRATED CONSTRUCTION TECHNIQUE OF BEIJING SOUTH RAILWAY STATION

Beijing South Railway Station is a large traffic hub of state-owned railway, subway, suburb railway, bus and taxi. etc. It is also the first express railway origin stop. During construction, many difficulties are overcome, such as large project scale, tight construction period, complex and special underground structure, difficult installation of steel structure, etc. Many measures and new techniques are adopted, such as large- diameter rotary-dig drilling perfusion pile technique, track layer highly-supported formwork technique, massive concrete technique, steel pipe self-compacting concrete technique, track layer steel joint technique under dynamic load, space steel structure intonation technique, safe construction and protection of existing line, group- tower operation anti-collision technique, new green energy application and so on. ＂Achievements of Beijing South Railway Station Integrated Technique＂ have been appraised by experts. Its integral construction technology has reached the advanced level in China and large-span space steel construction technique has reached the internationally advanced level.
