Abstract

The invention discloses a mounting method of a concrete hollow anchor rod tool. When used for inverted mounting of a hollow anchor rod, the mounting method comprises the following steps: 1, a hole isformed and cleared, specifically, the straight hole (28) is drilled in rock or concrete (27) through a drilling rig, then the hole is broached through broaching equipment, and then the hole is clearedthrough a hole clearing device; 2, mounting is conducted, specifically, hollow self-bottom-expanding anchor bolts are assembled firstly, a rubber sleeve (30) sleeves a rod body (1) and is located ona middle rod (22) part, then the rubber sleeve (30) is glued to the rod body (1) through glue, and then the assembled hollow self-bottom-expanding anchor bolts are inserted into the straight hole (28); and 3, grouting is conducted, specifically, through an injector, a grouting material sequentially passes through a rod body inner hole (9) and a wedge block inner hole (24) and then is injected intothe hole bottom of the straight hole (28), after the grouting material overflows from an air guiding pipe (32) on a large scale, grouting is stopped, an anchor rod cap (29) is mounted at the exposedend (6) to block the rod body inner hole (9) to prevent the grouting material from flowing out, and after the grouting material is solidified, the hollow self-bottom-expanding anchor bolts are mounted.

Description

technical field [0001] The invention relates to a bolt tooling, more specifically relates to a method for installing a concrete hollow bolt tooling, and belongs to the technical field of anchoring. Background technique [0002] There are usually two anchoring methods for anchor rods: cemented anchoring and mechanical anchoring. The cemented anchorage is consolidated by the poured cement and then provides the anchoring force. For example, the planting bar technology, the planting bar glue can provide large anchoring force and high reliability because of its high strength; however, the planting bar glue is not resistant to temperature and moisture. And aging problems, can not meet the engineering needs of some special environments. [0003] Mechanical anchoring mainly relies on the frictional resistance generated by the extrusion between the expansion head and the wall of the anchor hole to provide anchoring force; however, due to the limited depth of engagement between the a...
