System for covering and protecting buried pipes or cables

A system for covering and protecting buried pipes or cables, comprising:

• a plurality of covering and protection plates, each covering and protection plate having a first face and a second face opposite to the respective first face, and including a first end portion and a second end portion opposite to the respective first end portion, each covering and protection plate including at least one first assembly through-opening disposed on the first end portion of the respective covering and protection plate and opening respectively into the first and second faces of the respective covering and protection plate, and a second assembly through-opening disposed on the second end portion of the respective covering and protection plate and opening respectively into the first and second faces of the respective covering and protection plate, and
• a plurality of assembly devices adapted to allow the assembly of adjacent covering and protection plates at cover areas, each assembly device comprising:
• a first assembly member including a first bearing portion having a first bearing surface configured to bear against the first face of a covering and protection plate, and a first assembly portion configured to extend through a second assembly through-opening provided in a covering and protection plate,
• a second assembly member including a second bearing portion having a second bearing surface configured to bear against the second face of a covering and protection plate, and a second assembly portion configured to extend through a first assembly through-opening provided in a covering and protection plate, the second assembly portion of the second assembly member being configured to cooperate with the first assembly portion of the respective first assembly member so as to assemble, in use, two adjacent covering and protection plates at a covering area,
• a blocking member configured to cooperate with at least one of the first and second assembly portions of the respective first and second assembly members so as to block the first and second assembly portions in a relative assembly position.
