Benefits of technology
This patented technology improves upon existing methods used during construction projects when attaching cables or ropes onto rocks underground. It includes a special structure called a shell system attached to one part of each anchor cord's terminal ends. When pulling up these wires from their original positions they pass through holes formed within them until reaching the bottom of the water level at which point they fall downwardly towards the ground below. These connections allow the anchor wire to stay secure even if there were any differences between different locations along its route. By doing this, the technical effects include improved stability over long periods without requiring expensive equipment such as grout pumps or other temporary support measures.
Problems solved by technology
This patented technical problem addressed by the present patents relates to improving strength against damage caused during construction or maintenance operations on rockside surfaces such as tunnels. Traditional steel ropes have limitations when trying to protect these areas due to their low resistance towards cracks formed through impact from surrounding soil particles. To address this issue, researchers developed new techniques called fiber composites (FRC) technology, specifically using fibers made up of strong materials like glass strands embedded within resin matrix layers. These FRC technologies offer improved durability compared to older types of cables. However, they also require longer periods before being able to perform effectively.

The invention discloses a reinforcing device and method for a rock slope containing a weak interlayer, and relates to the technical field of slope reinforcing. The reinforcing device comprises a shell mechanism, wherein a drawing reinforcing mechanism is arranged in the shell mechanism in a lifting mode, a rod piece in the drawing reinforcing mechanism drives a reinforcing body to be opened with the rod piece as the center in the rising process, and four guiding mechanisms are fixedly arranged at the top of the inner side of the shell mechanism. According to the reinforcing device and method for the rock slope containing the weak interlayer, a concrete column after anchor cable grouting forming is reinforced, the local strength performance is enhanced to achieve the effect of good internal reinforcing of the rock slope containing the weak interlayer in a mining area, then the situation that shearing damage occurs to the vertical plane of the intersection of the rock slope and the weak interlayer due to uneven stress is avoided, and the shearing force direction of the sliding surface is beneficial to the change of the slope; and meanwhile, the reinforcing device is easy to manufacture, the actual length of the device is conveniently determined according to the depth of the weak interlayer, in addition, after short-term reinforcing, the reinforcing device can be recycled, and the using efficiency is improved.
