grout curtain in dam

This grout curtain may be constructed by drilling and grouting from a gallery within the dam, from the top of a specified thickness of concrete, or from the top of foundation rock. If a gallery is provided, then a series of drain holes will be drilled from the gallery and

An entire curtain wall of grout can be constructed in an earthen dam when the leaks might be corrected at considerably lower cost by identifying the problem area. With cracked concrete dams the location is typically quite obvious.

Grout curtains are thin, vertical, grout walls installed in the ground. They are constructed by pressure-injecting grout directly into the soil at closely spaced intervals. The spacing is selected so that each “pillar” of grout intersects the next, thus forming a continuous wall or curtain.

1. The grout curtain was made under conditions of a head on the damp up to 12.5 m under the protection of a temporary blanket placed on natural alluvium; the blanket reduced the gradients of the head in the zone of grouting and provided normal conditions of conducting it. 2. The combined method of grouting used made it possible to save materials and reduce the estimated cost of the curtain by
