Combined jacking pipe piece structure connecting system of large-span underground space and construction method
The invention provides a large-span underground space combined jacking pipe piece structure connecting system and a construction method.The connecting system comprises two jacking pipes, each jacking pipe is in a C shape, the two jacking pipes are horizontally and adjacently arranged, openings of the two jacking pipes are opposite, each jacking pipe is formed by longitudinally connecting a plurality of jacking pipe rings, and the jacking pipe rings are arranged in the C shape; each pipe jacking ring is composed of an L-shaped prefabricated pipe piece top plate, an L-shaped prefabricated pipe piece bottom plate and a linear prefabricated pipe piece outer side wall. The middle columns are used for connecting the top ends and the bottom ends of the openings of the two top pipes together; the reinforced concrete notched top beam is used for connecting the top joints of the two top pipes together; the reinforced concrete notched bottom beam is used for connecting the bottom joints of the two top pipes together; wherein the reinforced concrete notched top beam and the reinforced concrete notched bottom beam are both U-shaped notched beams. Construction can be simplified, and risks are reduced.
本发明提出一种大跨地下空间的组合顶管管片结构连接体系及施工方法，该连接体系包括：两条顶管，每条该顶管呈C形，该两条顶管水平紧邻排布、开口相对，每条顶管由若干顶管环纵向连接而成，每个顶管环由呈L形的预制管片顶板、呈L形的预制管片底板以及呈一字形的预制管片外侧墙构成；若干中柱，用于将该两条顶管的开口的顶底两端连接到一起；钢筋混凝土缺口顶梁，用于将该两条顶管的顶部接缝处连接到一起；以及钢筋混凝土缺口底梁，用于将该两条顶管的底部接缝处连接到一起；其中，该钢筋混凝土缺口顶梁和该钢筋混凝土缺口底梁均为U型缺口梁。能够简化施工，降低风险。
