Hollow grouting anchor manufacturer Huizhixin

Hollow grouting anchor assembly structure
The barbs on the hollow grouting anchor head can position the anchor in the drilled hole and ensure that the rod body is well centered.

The most important component of the hollow grouting anchor body assembly plays a major role in anchoring and support.

The grout stopper maintains the grouting pressure during the grouting process so that the grout can fully fill the gaps in the surrounding rock.

The backing plate bears greater stress on the surrounding rock.

The nut concentrates the stress of the surrounding rock on the backing plate.

The main technical performance parameters of hollow grouting anchors

The technical performance parameters of the series of high-strength and lightweight hollow grouting anchors are as follows. If the user has special requirements, our company can redesign it To be met

Construction technology

Use a drilling rig to drill holes according to the designed aperture and depth and clean up the gravel in the space. .

Connect the anchor head to one end of the rod body and insert it into the drilled hole. Hang the barb on the anchor head at the bottom of the hole.

Install the stopper plug, backing plate and nuts. And tighten the nut.
