                 8) For tainter gates which run under high water
                   head with sudden expansion gate slots, the
                   maximum deviation of the distance between the
                   side track  s water stop seat base surface center
                   line and the sluice hole center line is ±2   0
                   mm; the maximum deviation of the side track  s
                   water stop seat base surface curvature radius is
                   ±3   0mm, and the deviation direction shall be
                   in accordance with the deviation direction of the

                   between the side track  s water stop seat base surface and gate leaf outer cambered
                   surface shall be no larger than ±1   5mm.
                 9) When the steel beam of the tainter gate hinge is installed independently, the max⁃
                   imum deviation of the steel beam center  s travel, elevation and the distance to the
                   center line of the sluice hole shall be ±1   5mm. The tilt of the hinge steel beam is
                   shown in Figure 4   1   2. The deviation of the horizontal projection size shall be
                   controlled to ensure that the deviation of L shall be no larger than1/ 1000 of L.
                 10) The maximum elevation deviation of the horizontal steel lining is ±1   5mm. The
                   maximum deviation of the distance between the lateral steel lining and the sluice

                   hole center line is  mm. The maximum surface flatness tolerance is 4   0mm.
                               -2   0
                   The maximum perpendicularity tolerance is 1/ 1000 of the height and shall be no
                   larger than 4   0mm. The staggered displacement of composite surfaces shall be no
                   larger than 2   0mm.
                 11) When embedded parts have been well adjusted, adjusting screws, anchor slabs
                   and bolts shall be welded firmly as per the requirements of the design drawings to
                   make sure that embedded parts have no deformation or displacement in the
                   process of second⁃stage concrete casting.
