Abstract

The invention discloses a sectional and modular combined anchor rod capable of resisting large deformation and impact and an assembling method of the combined anchor rod. An outer anchor module of the combined anchor rod comprises an outer anchor end, anchor tubes and anchorage piers serving as connecting parts of the anchor tubes, wherein an anchoring agent is used for bonding the outer anchor module and a drill hole wall, and the function of a total-length bonding type anchor rod is realized; an inner anchor module comprises an outer anchor end, anchorage piers, springs and screw rods, the screw rods compress the inner anchor springs under the traction of the outer anchor end, anchorage force dispersely acts on each anchorage pier, the anchorage piers transfer the acting force to the anchoring agent in a pressure form, and the function of a pressure dispersing type anchor rod is realized; the inner anchor module and the outer anchor module are in parallel before breakage of the anchor tubes, the auxiliary anchoring function on surrounding rock is realized, and buffer yield and timely secondary high-strength supporting on the surrounding rock are realized after breakage of the anchor tubes.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering support, in particular to the support technology for rock mass engineering with high stress and large deformation or impact tendency. Background technique [0002] Bolt support is an important means of stability control in geotechnical engineering such as mines, tunnels, and slopes. During the research and application of bolt support, relevant scientific and technical personnel have developed a large number of various bolts and successfully solved a large number of engineering support problems. However, most of the existing bolts are difficult to adapt to rock mass engineering with high stress, large deformation and impact tendency. According to the stress and deformation characteristics of this type of rock mass engineering, the more effective bolt form is a high-strength bolt with yield characteristics. Its basic requirement is not only to have sufficient deformation capacity ...
