Characteristics of the product:1.Combined the functions of anchoring bolt and slip casting tube into one. It functions as slip casting tube during slip casting, then it functions as bolt after slip casting and no need pulling it out.2.Hollow design makes the anchoring bolt achieve the slip casting tube function, that prevent loss and erosion of the mortar when the slip casting tube is extracted in traditional installation.3.Full slip casting, pressure slip casting is available, that can improve the quality of the work..4.All kinds of accessories offers good mediate property to the anchoring bolt. The mortar can cover the whole length of the bolt, and that avoid its rustiness, long term supporting can be achieved. 5.Easily installation. Packing plate and nut can be installed conveniently without processing threads on site. Features and Advantages: - Particulary suitable difficult ground conditions - A high rate of installation since drilling,placing and grouting can be performed in one single operation. - Self drilling system eliminates the requirement for a cased borehole
