Recyclable composite anchor rod and construction method thereof

Abstract

The invention relates to a recyclable composite anchor rod and a construction method thereof in the field of anchoring in geotechnical engineering. The recyclable composite anchor rod comprises a hot-melt force transmission belt (2), a steel bar or a steel strand (3), a hollow channel (4) and a cement anchored body (1), wherein the cement anchored body (1) is a part connected with a rock-soil body (5) to provide uplift-resistance bearing capacity; the transfer of the uplift-resistance bearing capacity of the anchor rod is realized through the holding function of the hot-melt force transmission belt (2); and the recycle of the anchor rod is realized through melting. The invention realizes the convenient recycle of the main stressed component of the anchor rod while enhancing the uplift-resistance bearing capacity of the anchor rod, has the advantages of high recycle rate, convenient recycle construction, low manufacturing cost and prominent environmental benefit, successfully solves the problem that the construction anchor rod exceeds the land use red line under the ground in the city, can be widely applied to the field of engineering such as bracing of foundation pit and the like, and can be popularized and used in the soft soil zones.

AI Technical Summary

Benefits of technology

This patented new type of material for anchors has improved their ability to withstand pulling forces without losing them permanently or causing damage from external factors like weathering over time. It also makes it easier to recover these materials by reducing the amount needed during maintenance work compared to traditional methods that require removal before they are recovered again. Additionally, this technology allows for easy replacement when necessary while maintaining good performance even at high temperatures. Overall, this innovation improves safety measures against buried constructions due to better support provided through tensioned rods installed on top of existing foundations.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the efficiency and effectiveness of recovering buried objects from excavation projects or rehabilitation facilities due to the difficulty involved with attaching conventional reinforcement materials to these structures without damaging them over an extended period of usage. Existing solutions involve complex processes involving connecting different parts together mechanically, making assembly more challenging than desired. Therefore there exists technical problem related to developing new types of retrieving bolt systems that overcome issues associated with traditional connections between components while also being able to reuse after they were installed.
