    摘要: Um ein aus dem Erdreich oder Bauwerk ausbaubares Zugglied (1) herzustellen, wird dessen Zentralglied (2) vollständig durchgetrennt. Wenn das Zugglied (1) weiter geschwächt werden soll, wird nebst dem Zentralglied (2) noch mindestens ein Aussenglied (3) vollständig durch­getrennt. Entweder um die Trennstelle (4) des Zentral­gliedes (2) herum oder um die beiden Trennstel­len (4, 6) des Zentralgliedes (2) sowie des Aussenglie­des (3) wird an das Zugglied (1) ein Stützelement (5) angebracht. Durch Anwendung einer Last wird das Zug­glied (1) im Bereich der Trennstelle (4) des Zentral­gliedes (2) bzw. im Bereich der beiden Trennstel­len (4, 6) des Zentralgliedes (2) sowie des Aussenglie­des (3) abgerissen, so dass das Zugglied aus dem Erd­reich bzw. Bauwerk grösstenteils herausgezogen und ge­gebenenfalls wieder verwendet werden kann.

    摘要: An injection unit (10) for injecting consolidating fluid mixtures under pressure into the soil (T), comprising:
    - an outer cylindrical body (11);
    - at least one outlet lateral nozzle (12) defining an injection hole (12a) substantially perpendicular to the axis of the central longitudinal outer cylindrical body (11) and
    - a conduit (13), for connecting the upper inlet (11a) to the outlet nozzle (12);
    wherein the conduit (13) has along its axial extent a section progressively decreasing from the upper entrance to the nozzle, so that the fluid mixture (M) which flows along the conduit (13) acquires a progressively increasing speed, and
    wherein the conduit (13) and the injection hole (12a) of the outlet lateral nozzle (12) have one or more stabiliser ridges or fins (14) which are formed and extend along their surface, from the area of the upper entrance to the outlet of the injection hole, and have the function of stabilising and making laminar the flow of the fluid mixture (M) to enable a high efficiency to the injection head (10) and a high power to the jet emitted by the outlet lateral nozzle (12).

    摘要: The invention relates to anchorage assembly (20), comprising a tendon (10) made of strands (12), a first part (C) with the strands (12) passed through individual perforations of an anchor head (30), a second part (B) with an intermediate portion of the tendon (10) placed within a first tubular member (24) able to receive a removable protective product (38). The strands (12) have said end portion passed through on one hand an opening (27) formed in a bearing plate (26) disposed within the structure (42), and on the other hand said individual perforations of said anchor head (30) which is placed outside of the front face (40) of the structure (42), wherein the anchor head (30) has an outside diameter (D5) smaller than the diameter (D4) of said opening (27) of the bearing plate (26), wherein it further comprises a removable locking system (32) interposed between said anchor head (30) and said bearing plate (26), the presence of the locking system (32) preventing thereby the anchor head (30) to enter said opening (27) and said second tubular member (24) outlet.
