Method of protection of pile foundation of bearing support against soil frost heave forces Method of protection of a pile foundation of a bearing support against soil frost heave forces includes drilling of wells along the circumferential perimeter for the depth exceeding the depth of seasonal soil freezing, installation of one anchor element in each well in the form of a pipe with the length exceeding the depth of the well for the length of surface ends, and connection of the surface ends of anchor elements with the pile foundation of the bearing support. The anchor elements in the form of a pipe are made of a polymer material, which preserves high elasticity under winter soil temperatures, there are perforations at the deepened end sections of the anchor elements, through which via pipelines inserted into the tubular anchor elements they inject a hardening composition to form volume counterweights on the bottom of the wells as a result of an expanded area of interaction and engagement of the hardening composition with the soil, anchor elements and with the pile foundation. Connection of the surface ends of the anchor elements in the form of pipes with the pile foundation of the bearing support is carried out by the formation of a solid connection platform from a hardening mass, partially deepened into the surface soil. |

Method of soil reinforcement includes submersion in soil of a tubular injector, having outlet holes and two outlet channels, and supply of a hardening solution under pressure through the first channel of the tubular injector at 200-300 atmospheres with the rotation of the injector, providing for the damage of the soil structure and formation of the reinforced area in the soil. As the injected solution they use a polymer hardening solution, through the second channel a stabiliser is supplied, which, when mixed with the injected solution, provides for its quick setting and non-washing under the action of ground waters, the produced columns transmit load from the structure weight to the bearing layers of the foundation. |

Excavator working tools contain a boom with head blocks and saddle bearing, handle comprising a beam and head, installed in the saddle bearing; bucket comprising side, front, rare walls and bottom; bucket suspension blocks. The handle head is made in form of the truncated pyramid, its faucets are top, bottom and side walls. The pyramid rectangular bases are located at angle over 25° to each other. The smaller base is equal to the handle beam cross-section. The larger base is equal to rare wall of the bucket, and is rigidly secured on it. Top and bottom parts of the side walls of the bucket have shoulders locked in symmetrical slots on sides of the head. The bucket bottom is hingedly installed in brackets on the bottom wall of the head. In the head cavity the pair of brackets of the bucket suspension is installed. |

Construction kit of quickly erectable collapsible frames of wave-shaped translational shells Construction kit of collapsible frames of wave-shaped translational shells comprises bearing elements (ribs) and connection assemblies (connectors), with the help of which they assemble unified frame modules in the form of adjacent spatial isosceles right triangles, hypotenuses of which are identical arched ribs, and legs are made rectilinear or arched. The surface of the shell is formed by the method of translation - reciprocal movement of the flat wave-shaped generatrix along its perpendicular wave-shaped guide; as the generatrix and guide translational shell they use mutually perpendicular curves made of alternating convex and concave identical arched hypotenuses. Connection joints of the frame ribs are made of two types of connectors. |

Construction kit of quickly erectable collapsible frames of wave-shaped rotational shells comprises bearing elements (ribs) and connection assemblies (connectors), with the help of which they assemble unified frame modules in the form of adjacent spatial isosceles right triangles, hypotenuses of which are identical arched ribs, and legs are made rectilinear or arched. The surface of the shell is formed by the method of rotation of a flat wave-shaped generatrix around the axis located together with it in a single plane; as the generatrix of the rotational shell they use a continuous curve, consisting of alternating convex and concave identical arched hypotenuses. Connection joints of the frame ribs are made of two types of connectors. |

This invention relates to flameproof steel structures with at least one flameproof panel covering a steel structure. The panel includes a perforated metal plate (14), an inner expanding flameproof layer (12) of certain thickness (t1) on the inner side of the perforated metal plate (14) and an outer expanding flameproof layer (13) of certain thickness (t2) at the outer side of the perforated metal plate (14). The flameproof layer stretches via the perforated metal plate (14). A detachable mechanical fixture is used for detachable connection of at least one flameproof panel to the steel structure. Besides, the invention relates to a panel for steel structure protection. |

Clutch, in particular for anchor rods connection Group of inventions relates to clutches to connect links with male thread, to clutch systems, to injection drilling anchors, and to methods of connection of two carrying links. The clutch contains mandrel-type clutch coupling with holes at two opposite sides having female thread for screwing in, at that between both female threads of holes for screwing in on the internal side of the clutch coupling the looking radially inside installation shoulder is formed; at that between the installation shoulder and female threads the appropriate radial recess is made, it borders with runout of the adjacent female thread; at that in both recesses the elastic strained O-ring is installed, and at that in unloaded state of O-rings their outside diameter is larger then internal diameter of the installation shoulder and/or larger or equal to internal diameter of female thread. Engagement has pressure ring, its outside diameter is below or equal to internal diameter of the installation shoulder. O-rings have binding face that passes to abutment to one of both side surfaces of pressure ring in radius interval, that in case of the O-rings orientation concentric to the pressure ring partially crosses the radius interval of the side surfaces of the pressure ring. |
