Grouting adhesion prestressing force yielding anchor rod and construction method thereof
The invention discloses a grouting adhesion prestressing force yielding anchor rod and a construction method thereof, and relates to the technical field of rock-soil anchoring and engineering supporting. The yielding anchor rod comprises an anchor head, a rod body, a yielding sleeve and a bearing cushion plate, wherein a corrugated casing pipe is inserted in the front part of the yielding sleeve;the outer part of the rear part of the yielding sleeve is cooperated with the bearing cushion plate, and the inner part of the rear part of the yielding sleeve is provided with an inner slider; the rod body penetrates through the inner slider, the yielding sleeve and the corrugated casing pipe in sequence to be connected with the anchor head; the rod body and the inner slider are in force transferring cooperation; a cooperation surface of the inner slider and the yielding sleeve is provided with a plurality of annular through holes; and the annular through holes independently communicate withthe yielding sleeve and the corrugated casing pipe. The anchor rod disclosed by the invention has the functions of releasing energy, yielding, carrying out prestressing force, carrying out whole-length adhesion and the like, and is used for realizing permanent engineering supporting.
本发明公开了一种注浆粘结可预应力让压锚杆及其施工方法，涉及岩土锚固和工程支护技术领域，其中，让压锚杆包括锚头、杆体、让压套筒和支承垫板，所述让压套筒的前部内插有波纹套管；让压套筒后部的外部与支承垫板配合，内部设有内滑件；所述杆体依次穿过内滑件、让压套筒、波纹套管后与锚头连接，所述杆体和内滑件之间传力配合；所述的内滑件与让压套筒的配合面上设有多个环向通孔；所述环向通孔分别与让压套筒和波纹套管连通。本发明的锚杆具备释能让压、预应力、全长粘结等功能，用于永久工程支护。
