Embodiment
[0021] Example: such as Figure 1-7 As shown, the automatic anchoring device of the present invention includes: a memory alloy rod 1 and a sleeve 2 . The memory alloy rod 1 is processed into a shorter cylinder with a diameter greater than the middle part of the rod body at both ends. Sleeve 2 The overall shape of the sleeve is symmetrical at both ends, and the wall in the middle of the sleeve is cut equidistantly along the direction of the generatrix to form strips with the same width and length, and the two ends of each strip-shaped wall are still in line with the front and rear The uncut barrel walls are well connected. There is a horizontal tooth pattern 201 outside the middle of the strip-shaped tube wall, and there are horizontal concave grooves 202 outside the two ends of each strip-shaped tube wall. The concave engraving 203. The two ends of the sleeve 2 are internally threaded, and there is an opening whose diameter matches the diameter of the memory alloy rod 1 mid...

The invention belongs to the technical field of geotechnical engineering, and particularly relates to an automatic anchor device which consists of a memory alloy rod and a sleeve. Compared with the anchor method of the traditional anchor bolt, the automatic anchor device can use the shape memory effect and self-sensing characteristic of memory alloy, a driving force of the memory alloy is used for anchor, the problem that an anchor force of the traditional anchor bolt is reduced due to the fact that the combining between an anchor part and a rock drill hole loses effectiveness is solved; and the anchor force of the automatic anchor device in the rock drill hole is not reduced due to the deformation and breakage of the rock drill hole, so that the anchor supporting is stable, the anchor force is large, and the automatic anchor device has a wider application prospect in the field of the geotechnical engineering.
Description
technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to an automatic anchoring device. Background technique [0002] With the development of civil engineering, civil engineering is becoming more and more intelligent, and the use of intelligent materials has received more and more attention. Among them, memory alloy is an important and widely used intelligent material, which is different from traditional Compared with civil engineering materials, it has self-sensing characteristics and shape memory effect, and has excellent mechanical properties, high strength and light weight. In the anchor support widely used in geotechnical engineering, the decrease of the anchor force of the support over time is an important role in the failure of the anchor support structure, especially in the dynamic surrounding rock environment, the traditional bonded anchor and mechanical When the type anchorage is used in such com...
