Sluice Gates Installation

Water Check Valves Installation Installation A great deal of care I taken during manufacturing and assembly to ensure accuracy in mating the focus of door and frame. It is essential therefore that the sluice gates be erected carefully, free from distortion and under no circumstances, the door, wedges, guide strips be dismantled for fixing. This will prevent damage to the faces and distortion. The following guidelines would help: Wall Mounting Sluice Gates (Spigot Back) With each size of sluice gate a drawing depicting block out details for foundation bolts, shall be given, well before delivery of equipment. Box out the leaving pockets in the wall. Make a rigid template marking at least 3 foundation bolt holes besides, one each on extension guide, spaced far apart, adjacent to the aperture. Timber template would do. Drill bolt holes, preferrably tapped holes. Mark horizontal and vertical center lines of the aperture, on the template, Also denote the wall side and frame side thereon. Fit foundation bolts in the three template holes, ensure bolt projections are square with the template face. Fill the 3 corresponding pockets with stuff non shrink grout. Now place the template with the 3 bolts fixed thereon, flush with the wall at the intended position, use plump line and the marked center line. Now press the foundation bolts into the grout. Burry as much as is essential leaving the rest protruding outside the template (to allow for thickness of frame, a washer and a nut plus a little extra). Re-check fro verticality of template vis-a-vis intended location, restrain template from moving until grout has cured. Fit remaining foundation bolts to the frame from the wall side and secure with a washer and nuts from the frame side. Remove template when the grout has cured. Insert steel packing pieces (washers////0 20 mm thick on the 3 locating bolts and the position the frame using these 3 bolts which are now stiff. The remaining bolts also get located inside pockets awaiting grout. Tighten nut (with a washer) on the 3 locating bolts without imparting undue strain to the frame. Check for plump and the mating seat faces with a 0.1 mm feeler gauge. Where the gap is more than 0.1 mm, drive a wedge or packing between the frame and the wall. Repeat checking and wedging frequently throughout the installation process and avoid excessive wedging/packing to prevent high contact areas. Proper setting with a gap no more than 0.1 mm Position remaining foundation bolts square in wall pockets with the underside of nut just touching the frame, shuttle up around the frame and spigot ensuring the seat and face setting are not disturbed. Pour or force the fluid grout with pump in stages if necessary, between wall and the frame until all pockets are filled. Care must be taken to ensure there are no gaps around the spigot and between the wall to prevent leakage through such crevices. The extension guide (left and right) wherever applicable, are to be aligned with the top of frame (to permit uninterrupted movement of door), bolted thereon. Tighten the nuts, to hold the extension guide alongside the vertical wall (use shims/packing where necessary) onto the foundation bolt, grouted in pockets earlier (follow 8 and 9). Allow the grout to cure (at least a week) before tightening each nut attending to opposite nuts in turn. Excessive tightening is not necessary. Clean the sluice gate thoroughly, open, fully, apply grease on the screw, wedging device, seat and faces. Close gently. Ensure there are no scratches or damage to the seat and faces otherwise the equipment cannot be expected to operate within the permissible limit of leakage. Follow the same procedure to set guide brackets in wall, the head stock on the floor above and the extension spindle, so that the entire assembly operates smoothly in true alignment, the erected sluice gate acting as the datum and location from which to strike centerline and levels. Follow guidelines including for size of grout bolts, provided along with block out details. Wall Thimble Mounted (Flanged Back) before proceeding to position the wall thimble in the opening in the wall, ensure all taped holes for stud bolts on its flange are plugged by plastic or timber pegs to preclude cement concrete getting lodged in these holes. Position the wall thimble against the opening in the wall (look for the top sign) and ease the collar (in the flange resting against the wall. Ensure verticality of the wall thimble flange face using a pump line vis-a-vis two distinct marks provided in the middle of the top and bottom member of the wall thimble flange. Serious operational problems may occur if this is not done properly. Prop up and restrain the wall thimble before pouring grout around it. Immediately clean any cement solution that inadvertently comes on the flange face. Allow the grout to cure (atleast a week.) Do not remove the sluice gate from its timber crate until the site is ready for erection. No attempt should be made to remove the door form the frame. These are factory set. Only extension guides are loose pieces, to be erected after the gate has been erected. Remove al plastic / wooden pegs from the stud bolt holes in the wall thimble. Select 3 of them, far apart, around the aperture and fix 3 stud bolts of appropriate length into these. Tighten fully.
