The invention discloses a simple and rapid anchoring method and apparatus of a distributive sensing optical cable. A large cylinder is nested in a
flange, and hollow circular truncated cones are fixed at two ends of the large cylinder; a spring is arranged in the large cylinder,
metal clamping pieces are fixed at two ends of the spring, the other end of each
metal clamping piece is connected with a small cylinder, and the
flange, the large cylinder, the spring, the
metal clamping pieces and the small cylinder are coaxial; and a loose-sleeve distributive sensing optical cable passes through a circular hole on the
peripheral edge of the
flange to play an effect of temperature compensation and alignment. According to the optical cable anchoring apparatus, the elastic force is controlled by virtue of a
stiffness coefficient of the spring, the stress on a cross section of the loose-sleeve distributive sensing optical cable is uniformly distributed, and the optical cable is firmly installed; and moreover, the simple and rapid anchoring apparatus is small in size, simple in production, easy to operate, rapid to install, low in cost, small in micro-
bend loss of an
optical path, reliable in anchoring effect, suitable for the distributive sensing cables of different sizes, structures and cladding materials, and can firmly fix the distributive sensing optical cable on concrete, inside a rock and earth
mass or on the surfaces of
steel structures and concrete structures.
