1. A stabilized soil structure, comprising a fill, reinforcement strips extending through a reinforced zone of the fill situated behind a front face of the structure, and a facing placed along said front face, the reinforcement strips being anchored to the facing in respective anchoring regions, wherein the facing incorporates, in at least one anchoring region, a path formed for a reinforcement strip between two points of emergence situated on a rear face of the facing adjacent to the fill, and wherein said path includes two rectilinear portions respectively adjacent to the two points of emergence and each arranged to position the strip in a common plane of emergence perpendicular to said rear face, two curved portions respectively continuing the two rectilinear portions and arranged to deviate the strip from the plane of emergence, and a connection portion joining the two curved portions to one another and having at least one loop situated outside the plane of emergence wherein the facing has, in the anchoring region, a protective sheath receiving the reinforcement strip along said path and the protective sheath comprises two halves on both sides of the reinforcement strip, the two halves being sealingly assembled together.
2. The structure of claim 1, wherein the facing is made from elements in the form of panels, and wherein the rectilinear portions of said path each extend in the plane of emergence by at least half the thickness of a panel-shaped facing element.
3. The structure of claim 1, wherein the reinforcement strip has a width at most equal to half a thickness of the facing.
4. The structure of claim 1, wherein the facing is made from elements in the form of panels of cast material each having at least one protective sheath embedded therein.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A carbon dioxide laser machining method of a multilayer material, comprising:
applying carbon dioxide laser light to a machined part of a multilayer material having an insulation layer, and a first conductor layer and a second conductor layer deposited with the insulation layer in between; and
removing the first conductor layer and the insulation layer of the machined part to form one of a blind hole and a groove to a depth of the second conductor layer, such that a portion of the second conductor layer is not removed,
wherein the laser light is applied to the machined part in the form of pulses at an energy density of 25 Jcm2 or more with a beam ON time in the range of 1 \u03bcs to 10 \u03bcs, and
wherein the first conductor layer is removed with the laser light.
2. The method according to claim 1, wherein said energy density is greater than 40 Jcm2.
3. A carbon dioxide laser machining method of a multilayer material of applying carbon dioxide laser light to a machined part of a multilayer material having an insulation layer and a first conductor layer and a second conductor layer deposited with the insulation layer between and removing the first conductor layer and the insulation layer of the machined part to form a blind hole or a groove arriving at the second conductor layer, characterized in that the laser light is applied to the machined part in the form of pulses at an energy density of 25 Jcm2 or more with a beam ON time in the range of 1 \u03bcs to 10 \u03bcs,
wherein when the first conductor layer of the machined part is removed by applying a plurality of pulses, the application beam diameter of later applied pulses is made larger than that of earlier applied pulses.
