The utility model provides an immersed tube method tunnel tube festival installation axis regulating cover, includes roof and curb plate two parts, the outer contact surface of roof is the sphere, and has smooth finish, and the fillet is polished into to the outer contact surface periphery of roof, the annular structure of curb plate for having height and thickness, its thickness can be based on, and the heavy actual measurement axis misalignment of putting the tube coupling adjusts, adopt single groove to weld between roof and the curb plate and weld into whole, weld grinding to with curb plate surface parallel and level. The utility model discloses can be based on the actual axis misalignment who has installed the tube coupling has corresponding adjustment regulating cover curb plate thickness, simultaneously, because the adjustment effect that regulating cover produced be the whole dislocation adjustment of tube coupling, therefore the atress of butt joint GINA rubber waterstop does not exert an influence, can avoid the influence to engineering main part structural durability, regulating cover simple structure, with low costs, the construction degree of difficulty is little.
