Abstract

The invention relates to the field of building construction, in particular to a grouting anchor rod structure. The grouting anchor rod structure comprises an anchor rod body, a grouting channel is formed in the anchor rod body, a plurality of grouting holes communicating with the grouting channel are formed in the anchor rod body, and the anchor rod body is connected with a reserved hole formed in the ground in an inserted mode. A connecting hole communicating with the grouting channel is inwards formed in the outer wall of the anchor rod body, an abutting rod is slidably inserted into the connecting hole, and the abutting rod is connected with an abutting assembly which enables the end, away from the grouting channel, of the abutting rod to be inserted into soil. The invention further discloses a using method of the grouting anchor rod. The grouting anchor rod structure has the effect of improving the stability when the anchor rod body is fixed.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a grouting anchor structure and an application method thereof. Background technique [0002] Grouting anchor is a common tool in tunnel engineering, slope treatment engineering, and coal mine roadway engineering, and is used to support the rock surface for the first excavation. [0003] Such as figure 1 As shown, an existing grouting anchor includes an anchor body 1, the interior of the anchor body 1 is hollow, and the space inside the anchor body 1 is a grouting channel 11, and the grouting channel 11 runs through the top of the anchor body 1. On the surface, the outer surface of the bolt body 1 is provided with a plurality of grouting holes 12 , and the grouting holes 12 are communicated with the grouting channel 11 . The ground 2 is provided with a reserved hole 21 downwards, insert the bolt body 1 vertically downwards into the reserved hole 21, and then inject...
