Embodiment Construction

[0048] A grout stopper 3 as shown in FIG. 1 and FIG. 2 is composed of a flexible outer ring 4 , a hard inner ring 5 with a grouting hole 53 , and a locking member 6 with a longitudinal groove 63 . The flexible outer ring 4 is sleeved on the hard inner ring 5, and the locking part 6 is closely attached to the bell mouth of the hard inner ring 5, so that the grout stopper 3 formed in this way passes through the inner hole 62 of the locking part 6 It is threadedly connected with the surface of the anchor rod body 10 . The longitudinal groove 65 of the locking member 6 communicates with the inner cavity 50 of the hard inner ring 5 and the grouting hole 53 to form a grouting channel.

[0049] The flexible outer ring 4 is an inverted trumpet body with a cavity and the front and rear ends are connected. The front end 42 is small and thin, and the rear end 43 is large and thick. Its front end 42 is a high-elastic thin-layer ring, and the inner surface of the cavity is smooth, and can...

Abstract

The present invention discloses a slurry-stopping plug. It is formed from hard internal ring, flexible external lantern ring and retaining member. Said invention also provides the concrete structure of the above-mentioned every component. Besides, said invention also provides the slurry-injection joint matched with the slurry-stopping plug.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering anchoring and supporting, and relates to a multifunctional grout stopper device for anchor rods and a special grouting joint thereof. The device of the invention is suitable for bolt support of stratum structures in underground engineering, mining engineering, foundation pit and slope engineering and the like. Background technique [0002] In the process of underground engineering, mining engineering, foundation pit and slope engineering involved in geotechnical engineering, in order to prevent the formation from deforming, collapsing or destabilizing and endangering safety, a main support technology for strengthening the formation is to use bolts. The formation is reinforced through the high-strength tensile capacity of the bolt installed in the formation and the dense combination between the bolt and the grouting body around the bolt and the formation to improve the integrity of...
