Problems solved by technology

During on-site construction, there may be quality problems such as anchorage damage, fracture, and anchorage section displacement due to insufficient anchoring force of the anchor.
However, it is generally difficult to determine the anchorage quality, and it is necessary to measure the anchorage maximum load value of the anchor rod to verify the reliability of the support.

Abstract

The invention discloses an anchor rod (cable) drawing intelligent monitoring device, which comprises an anchor rod (cable), a hydraulic oil cylinder, a hollow hydraulic jack supported on the ground surface and a displacement sensor box body with a built-in laser wireless displacement sensor, the hydraulic jack is arranged in an inner cavity of the hydraulic oil cylinder, and clamps are arranged atthe upper end and the lower end of the hydraulic jack, a measuring rod is arranged on the displacement sensor box body, and a probe arranged at the top of the measuring rod is adsorbed to the lower portion of the hydraulic oil cylinder through a small powerful magnet. A traditional hydraulic mode is further improved, the intelligent wireless transmission technology is well combined, the stress condition and the relation between force and displacement in the anchor rod drawing process can be monitored in real time in the whole process, the anchoring quality and the maximum load value of the anchor rod are inspected, the supporting reliability is verified, and meanwhile, the quality problems of damage and breakage of the anchor rod, displacement of an anchoring section and the like possiblycaused by insufficient anchoring force of the anchor rod in field construction are solved.

Description

technical field [0001] The invention relates to the technical field of anchor rod (cable) pulling test technology, in particular to an intelligent monitoring device for anchor rod (cable) pulling. Background technique [0002] In engineering fields such as mines, railways, highways, tunnels, bridges, and slopes, bolt (cable) support, as an important support means, is the most commonly used and effective support method in construction. Therefore, it is necessary to measure the anchoring quality of the anchor rod to judge whether the support strength is up to standard and whether the support is reliable. During on-site construction, there may be quality problems such as damage, breakage and displacement of the anchorage section due to insufficient anchoring force of the anchor. However, it is generally difficult to determine the anchorage quality, and it is necessary to measure the maximum anchorage load value of the anchor rod to verify the reliability of the support. The b...
