摘要
A system for constructing underwater impermeable protective sheathings of hydraulic structures (10) or parts of them. At least one reference line is provided on the surface area (11) to be protected and a protective sheathing is constructed underwater by positioning and stretching impermeable sheet materials (12) over the area (11), keeping one lateral edge of each sheet material (12) parallelly aligned to said reference line, and maintaining hydrostatic balanced conditions between the pressures on the front and rear faces of each sheet material (12); the sheets (12) are afterwards watertight connected along their edges and anchored to the surface (11) of the hydraulic structure (10) by mechanical anchorage devices (13, 20, 21, 24).
