Recyclable sand-consolidated anchor head prestressed anchor, anchorage jack and its application method

Abstract

The invention discloses a retrievable sand consolidation anchor head prestressed anchor rod, an anchoring jack and an application method thereof, and belongs to the technical field of geotechnical engineering. The retrievable sand-consolidated anchor head pre-stressed anchor includes a bolt body, a rigid frame, a load member, a sand column, a pressure receiving member, a cut-off member, and an anchor pier. The anchoring jack includes a force transmitting frame, a first guiding plate, a second guiding plate, and a housing. The application method includes an anchoring method using the retrievable sand-consolidated anchor head prestressed anchor rod and a method of recovering the retrievable sand-consolidated anchor head pre-stressed anchor rod. After the anchoring of the reclaimed sand-consolidated anchor head pre-stressed anchor rod, the bolt body can be recovered and reused, and the operation is simpler and more environmentally friendly.
