Head, the solid screw bar wall other end are sequentially installed with stop grouting plug, backing plate and nut, the novel slurry filling anchor system from inside to outside
It further include mobile pressing plate and slip casting shell, the slip casting shell includes cylindrical steel tube, and the cylindrical steel tube coaxial spaced is set in solid
Outside screw rod, cylindrical steel tube tube wall is along multiple through-holes are axially arranged with, and cylindrical steel tube outer wall top, which is set with, is fixed with annulus, outside the annulus
Periphery is relatively fixed there are two foot-operated wing plate, and cylindrical steel tube inner wall edge is axially arranged with two bar shaped retention beads, two items
Shape retention bead is oppositely arranged, and the circular slab of threaded hole is equipped with centered on the mobile pressing plate, and mobile pressing plate periphery is opposite
If mobile pressing plate is screwed in solid screw by the threaded hole, while described two notches slide respectively there are two notch
It is fastened in two bar shaped retention beads of cylindrical steel tube.
Compared with prior art, the utility model has the beneficial effects that the utility model passes through outside anchoring rod and slip casting
The combination of shell not only can effectively be combined with rock stratum by way of slip casting and is not easily disconnected from, but also can avoid reducing using solid screw
Shear resistance, it is simple and practical in structure, and mobile pressing plate is added on anchoring rod, can slurries be played with pressurization, increased
Depth of penetration.
