  • Patent number: 11225829
    Abstract: Structure of fillings for openings comprising a sheet material panel, a frame set, seals, a shock-dampening and absorption system, and insulation materials. With the filling structure for openings, the kinetic energy of a shock wave from an explosion is converted throughout the surface of the filling into a potential energy of the building, i.e. the kinetic energy of the shock wave is absorbed into the building.
    Type: Grant

  • Patent number: 10508464
    Abstract: Structure of a facility for demining, investigating and testing of an explosive device which comprises several structural elements connected to each other for processing an explosive device. The elements comprise a chamber for demining, investigation and testing, and for the initial suppression of the potential explosion shock wave and primary collection of the explosive residues, a chamber for secondary suppression and secondary collection of the explosion shock wave, a chamber for final suppression of the shock wave including filtration and the final collection of the explosive residue and the shock wave spreading space. The chambers have openings in front, where shock wave deflectors have been placed and behind the openings have been placed barrier walls. In the chamber walls and the ceiling have been placed cameras, lights, lighting tunnels and ventilation equipment. Between the chambers are automatic opening and closing doors, and the building is covered with a composite cover.

  • Patent number: 9228313
    Abstract: The method for the restoration and reinforcement of scarps and a resulting reinforced structure is provided. The method includes of clearing the scarp surface under restoration, and of creating a pit (an excavation). The bottom of the pit is filled with mineral soil and is compacted as a foundation of a retaining wall. A protective filter made from draining mineral soil is installed on the foothill of the scarp, where the protective filter is surrounded by draining geotextile. The geogrid is placed on the surface of the regressed scarp and then anchored to the soil of the scarp by tensile ropes. A rigid support, such as a crib (grillage), is created on the protective filter and batter piles are driven under the rigid support. Then the retaining wall is constructed, consisting of layers of compacted soil that are surrounded by draining geotextile. The retaining wall is covered by erosion control mats, anchored to the draining geotextile of the soil layers of the retaining wall.
