Tunnel excavation complete equipment construction method based on cantilever heading machine
The invention provides a construction method of tunnel excavation complete equipment based on a cantilever heading machine. The construction method comprises the following steps: step (1), excavating a tunnel body; (2) primary supporting is conducted; (3) secondary lining construction of the tunnel is carried out; the tunnel secondary lining construction comprises tunnel inverted arch lining construction and tunnel arch wall lining construction; and (4) tunnel cable trough construction. The construction organization method is reasonable, the tunnel management effect is effectively improved, the construction operation environment is improved, sprayed concrete is mixed in advance in a concrete mixing station after a wet spraying manipulator is introduced in cooperation with a heading machine, and compared with previous dry spraying and wet spraying processes, the quality of the sprayed concrete is greatly improved, construction safety and quality are guaranteed, and the construction efficiency is improved. The construction progress is accelerated, and the method is worthy of vigorous popularization.
本发明提供一种基于悬臂掘进机的隧道开挖成套装备施工方法，包括以下步骤：步骤(1).洞身开挖；步骤(2).初期支护；步骤(3).隧道二次衬砌施工；隧道二次衬砌施工包括隧道仰拱衬砌施工和隧道拱墙衬砌施工；步骤(4).隧道电缆槽施工。本发明施工组织方法合理，有效提升了隧道管理效果，改善了施工作业环境，配合掘进机引进湿喷机械手后，喷射混凝土在混凝土拌合站提前拌好，相比于以前的干喷、潮喷工艺，大大改善喷射混凝土的品质，保证了施工安全和质量，提高了施工进度,值得大力推广。
