Therefore, the bag is used independently, and the bag is easily attached to or wound on the anchor rod body, so that the rod body and the cement paste grouting body lose or partially lose adhesion, the mechanical property of the anchor rod is influenced, and the bag has great side effect. In order to overcome the side effect, geotechnical cloth and plastic cloth which are large in thickness and not very soft are often used in engineering, but thicker cloth occupies larger anchor hole space and can only be used for anchor rods with larger anchor hole diameters. This application combines cage core and bag, the shortcoming and the side effect of bag exclusive use have been overcome completely, the attached or the winding body of rod of bag cloth has been avoided completely, can ensure that the body of rod bonds with grout fully, the beneficial effect and the effect of the fully reliable performance bag, and this application cage core and bag combine, can adopt thinner cloth preparation bag, occupation space is little can be used for the less stock of anchor eye diameter, the application range of bag stock has been expanded and the cost is low.
The cage core combines with the bag, and the cage core has effectively prevented that bag cloth from pasting and winding the body of rod, and the bag effectively prevents that earth mud from getting into the cage in-core, prevents that grout from being diluted by groundwater, and the grout that gets into the cage core is the controllable thick liquid of pure water-cement ratio and has avoided receiving anchor eye water, soil and mud sneak into and diluted to can ensure to form one and use the body of rod to use the cage core as the center to solidify the muscle grout slip casting body that forms by the controllable grout of pure water-cement ratio. As is known to all, the mechanical strength of reinforced concrete is generally several times higher than that of plain concrete, the mechanical strength of reinforced cement paste is also several times higher than that of plain cement paste, and the bonding strength of a rod body and the cement paste is also several times higher, so that the mechanical strength of the anchor rod can be greatly improved and the reliability is greatly improved by combining the cage core and the bag.
