Abstract

The present invention relates to an anchoring method, and is characterized by that under the anchor hole in which an anchor bar can be placed an anchor enlarged hole is cut, and in the anchor enlarged hole an anchor head which and rock-soil can produce end resistance between them is placed, and after the anchor head and anchor bar are connected, the concrete can be grouted. Said invention provides the condition required for anchor bar and anchor head structure. Said invented end load-bearing anchor bar includes anchor bar, its lower portion is equipped with lower sliding bar and forced pulling bar which can be opened, and also includes upper sliding bar, lower support bar and supporting plate, etc. It can fully utilize end resistance of rock-soil to greatly raise anchoring force.

Description

Technical field: [0001] The invention relates to the field of building foundations, in particular to the design improvement of an anchoring method and an anchoring piece. Background technique: [0002] At present, the design and construction methods of bolts at home and abroad are carried out according to the force form of pure friction (side resistance), and the side resistance of the rock and soil is what provides the reaction force for the bolt. According to this traditional design method and theory, the bolt material consumption is huge, the engineering cost is high, but the anchoring force is very small; if the required anchoring force is large, the length of the anchoring rod is very long, and the anchoring force is unstable. and loss over time. Invention content: [0003] The technical problem to be solved by this invention is how to increase the contact area between the anchor rod and the rock and soil, so that the anchor rod can not only be affected by the side r...
