摘要： A multiple trepan boring device for producing substantially large cuts in large works, such as concrete dams, comprises a drilling shaft adapted to be translationally displaced along its longitudinal axis and carrying a series of spaced apart cylindrical rotatable trepans each having a peripheral cutting surface and an annular cutting surface, the latter extending in plane perpendicular to the axis of the shaft and radially between the shaft and the peripheral cutting surface. Weights apply continuous downwards forces on the shaft and thus on the trepans. With the trepans resting on the top of the work to be cut, the trepans are rotated in place, and under the aforementioned forces the peripheral cutting surface of each trepan bores a hole until the shaft rests on the top of the work. Then the shaft is displaced translationally while the trepans continue to rotate thereby causing the annular cutting surfaces to remove a layer of the work extending between the shaft and the peripheral cutting surface. This procedure is repeated so as to produce a cut of a width corresponding to the outside diameter of the trepans by successive removal of crescent-shaped layers from the work. After the removal of each layer, the shaft is lowered along a distance corresponding to the difference in radii between the drilling shaft and the trepans.

摘要： A method for installing expansion joints in concrete dams using a sealing device includes the steps of boring a hole in the dam intended for receiving the sealing device at a distance from water retained by the dam, installing the sealing device in the hole, and completing the expansion joint by cutting the dam on each side of the hole such that the hole communicates with the downstream side of the dam and with the water on the upstream side thereof. The cut is also made to communicate with the hole and thus with the sealing device. Second and third holes are bored before installing the sealing device in the first hole with the second and third holes overlapping on each side of the first hole. The sealing device comprises a tubular and elastic cell adapted to be inserted and installed in the first hole and includes reinforcements spaced from each other. The sealing device is first positioned in the first hole with its reinforcements located opposite the second and third holes, and is then filled under required pressure with an appropriate fluid.

摘要： A sealing device for sealing an expansion joint cut in a concrete dam comprises a tubular cell made of an elastic material and provided at its upper and lower ends respectively with a rigid upper ferrule and a rigid and rounded lower ferrule. Cables are mounted between the upper and lower ferrules for preventing the longitudinal stretching of the cell. The cell includes two longitudinal reinforcements spaced one from another and disposed opposite the cut for preventing the radial deformation of the cell in the cut. A continuous peripheral space is defined on the cell between the lower ends of the reinforcements and the upper end of the lower ferrule to allow the cell to form a continuous peripheral seal against the walls of a hole bored along the expansion joint. A method for the installation of the expansion joint in the concrete dam using the sealing device is also proposed, wherein the sealing device is installed in a hole bored on the expansion joint, the reinforcements being positioned in the direction of the water flow. The cell is then filled and pressurized with appropriate fluids. The expansion joint is obtained by the completion of the cut.
