Field striking covering works construction method and its covering works device null

摘要

PURPOSE:To reduce a construction period by promoting execution efficiency and safety and to make it possible to have a wider working space. CONSTITUTION:After the deformation of an internal form 5 is prevented by deformation preventing rings 7, a shield machine 2 is driven by applying reaction force to beam members 16 buried in the existing linings 9 and, at the same time, after lining members are pressed by a plurality of press jacks 11 for specific hours through press rings 10, the press rings 10 are moved to a facing side by the press jacks 11 to assemble lining reinforced member 18. After that, a lining member injection space 21 for the following process is formed by sliding the whole internal form 5 to the facing side for a specific distance in conjunction with the deformation preventing rings 7, pushing jacks 3 and tension jacks 4.
