摘要： The device consists of first and second load receiving members 10, 14, a breakable member 20 (Figure 2) and a part-spherical washer 18 received in a seat 32 in the second load-receiving member. In use, a load is applied by way.of a rod or bar passing centrally through the load-receiving members 10,14 and the breakable member positioned therebetween, the rod or bar also passing through a central bore 34 in the washer 18 and being angularly movable because of the support provided by the seat 32. When a predetermined load is achieved, annular cutting surfaces 26, 40 on the load-receiving member cut the breakable member with a predominantly shearing action to indicate that the load has been achieved. Fractured parts of fingers 50 of the bearing member are retained between surfaces 24, 38 to be visible at the periphery of the device.

摘要： A constant-resistance and large deformation anchor cable and a constant-resistance device are provided. The constant-resistance and large deformation anchor cable comprises cables (7), an anchoring device (13), a loading plate (12) and clipping sheets (4). The upper end of cables (7) is fixed on the anchoring device (13) and the loading plate (12) by clipping sheets (4). The constant-resistance and large deformation anchor cable also comprises a constant-resistance device, and the constant-resistance device comprises a sleeve (8) and a constant-resistance body (5). The sleeve (8) is a straight tube. The constant-resistance body is conical, and the diameter of the lower end of the constant-resistance body is bigger than the diameter of the upper end of the constant-resistance body. The inner diameter of the sleeve (8) is smaller than the diameter of the lower end of the constant-resistance body. A cuneiform part is arranged on inner wall of the lower end of the sleeve (8), and the constant-resistance body (5) is arranged on the cuneiform part. The strength of constant-resistance body (5) is higher than the strength of the sleeve (8), thus the sleeve (8) generates plastic deforming and the shape of the constant-resistance body (5) is not changed, when the constant-resistance body (5) moves in the sleeve (8). The lower end of the cables (7) is fixed on the constant-resistance body (5). The constant-resistance and large deformation anchor cable and the constant-resistance device have the properties of constant-resistance and preventing fracture, and can detect and early warn the all process of the activity of the landslides and the causative fault.

摘要： This invention discloses an underground rock anchoring system comprising a rock bolt having a bolt shaft operatively locatable in an elongate rectilinear hole drilled into a hanging wall such that an end portion of the bolt shaft protrudes from the hole, the bolt shaft having a side wall defining a hollow internal chamber extending along at least part of the length of the bolt shaft, a bearing plate adapted to be fitted over the protruding end portion of the bolt shaft for bearing against a rock surface of the hanging wall; and fastening means for pulling the bearing plate taut against the rock surface of the hanging wall. The invention also extends to a rock anchoring method in which such system is used.
