the cover is equipped with pipe 4 on the stock 1 on ring 2 right side, 1 axis horizontal slip is followed to pipe 4, and pipe 4 can be with the shutoff of round hole 3 when being located the right-hand member, be equipped with multiunit connecting rod 5 between ring 2 and the pipe 4, every group connecting rod 5 comprises two mutual articulated connecting rods 5, and the other end of two connecting rods 5 in the same group respectively with ring 2, pipe 4 is articulated, 4 can make the one end of two connecting rods 5 mutual articulations remove to the direction of keeping away from stock 1 axis when moving left of pipe.

4 inside walls of pipe on open and to have a plurality of recesses 6, the right-hand member of every recess 6 all runs through to 4 right-hand members of pipe, all be fixed with a curved dog 7 on the stock 1 on the right side of every round hole 3, when pipe 4 is located the rightmost end of self removal orbit, every round hole 3 all is located one of them recess 6, and dog 7 on round hole 3 right side enables round

hole

3 and 6 right-hand members of recess and keep apart, when pouring concrete slurry into stock 1 in, slurry gets into the cavity between dog 7 and the recess 6 from round hole 3, last slip casting in-process, the mud pressure between recess 6 and the dog 7 crescent, pipe 4 remove left, and then make connecting rod 5 outwards strut.

Every recess 6 in all be equipped with a curved shell fragment 8, shell fragment 8 one end is fixed with 6 inside walls of recess, the other end is crooked to 1 axis direction of stock, when pipe 4 is located the rightmost end of self movement orbit, shell fragment 8 is located between 6 inside walls of recess and the 7 lateral walls of dog, shell fragment 8 also moves left along with pipe 4 is synchronous when pipe 4 moves left, until recess 6 and 7 separation backs of dog, the free end of shell fragment 8 contacts with 1 lateral wall of stock under the effect of self elasticity again, distance between 8 free ends of shell fragment and 1 axis of stock is less than the distance between 7 lateral walls of dog and 1 axis of stock promptly, and then prevent 4 automatic right resets of pipe.

The anchor rod 1 outer fringe face between ring 2 and pipe 4 on be fixed with packing ring 9, packing ring 9 is coaxial with anchor rod 1, packing ring 9 enables the mutual articulated one end of two connecting rods 5 and is greater than the distance between connecting rod 5 and the articulated one end of ring 2 apart from anchor rod 1 axis apart from the distance between the anchor rod 1 axis, the card is dead when preventing that two connecting rods 5 outwards strut.

The right end of the anchor rod 1 is fixed with a hollow cylindrical block, the inner diameter of the cylindrical block is equal to that of the anchor rod 1, the outer diameter of the cylindrical block is equal to that of the inner thread at the left end of the anchor rod 1, the outer thread is located on the outer edge surface of the cylindrical block, and the plurality of anchor rods 1 can be fixed with the outer thread through the inner thread when being connected in a left-right mode.

When the device is used, a drill bit is fixed to the left end of the anchor rod 1, the right end of the anchor rod 1 is connected with a drilling machine, the drilling machine drives the drill bit to drill at a positioning point through the anchor rod 1, an operator can connect and fix a plurality of anchor rods 1 through internal and external threads at two ends of each anchor rod 1 in the drilling process, so that the drilling depth of the drill bit reaches the design requirement, and in the continuous drilling process, as the anchor rods 1 are longer and longer, the anchor rods 1 inevitably bend and deform under the torque of the drilling machine, so that the aperture of the position where the deformed part passes is larger than the diameter of the drill bit;

after drilling is completed, a drilling machine is dismounted from the right end of an anchor rod 1, concrete slurry is injected, the inner diameter of a formed hole is larger than the diameter of a drill bit due to the bending of the anchor rod 1, so the inner diameter of the formed hole is also larger than the diameter of the anchor rod 1, the anchor rod 1 can still be in a bending state under the influence of gravity or installation accuracy, namely, the outer wall of the anchor rod 1 is in contact with the inner wall of the formed hole, at the moment, if direct grouting is carried out, no concrete slurry exists on one side of the anchor rod 1 in contact with the inner wall of the formed hole, the bonding effect of the anchor rod 1 and the surrounding soil layers is influenced, so the circular hole 3 for slurry to flow out of the circular hole is sealed by the circular tube 4 and the stopper 7 when the device is used for grouting, only needs to ensure that the leakage speed between the stopper 7 and the groove 6 is smaller than the grouting speed, the pressure in a cavity between the stopper 7 and the groove 6 can be increased continuously, the circular tube 4 is pushed leftwards, because the gasket 9 is fixed on the anchor rod 1 between the circular tube 2 and the circular tube 4, two connecting rods 5 can not clamp the circular tube 4 when the circular tube 4 moves leftwards, the circular tube 4 smoothly pushes the connecting rod 5 outwards, until the stopper 7 is separated from the groove 6, the stopper 7 and the groove, the slurry flows out, meanwhile, the slurry flows out, the circular tube 8, the full-contact of the circular hole can be prevented from the left end of the circular hole, the anchor rod 1, the circular hole, the full-free-supporting rod 5, the full-supporting effect of the anchor rod 1, and the circular hole can be improved, and the effect of the anchor rod 5, and the full-contact of the anchor rod can be improved, and the full-hole, and the full-of the full-free-hole, and the full-hole can be prevented, and the full-slurry flowing of the full-hole of the anchor rod 5, and the full-supporting effect of the full-hole can be prevented, and the full-slurry.

The utility model has the advantages of it is following showing:

1. the utility model discloses a connecting rod 5 laminates with stock 1 when drilling, even at the drilling in-process because stock 1's crooked ring 2, connecting rod 5 and pipe 4 can make the internal diameter grow of pore-forming, but connecting rod 5 can take lead outside strut earlier when slip casting, make stock 1 keep away from the pore-forming inner wall, guarantee that concrete mud can wrap up stock 1 completely, compare the fixed unchangeable support piece of shape among the prior art, this device is after the slip casting is accomplished, connecting rod 5 can support the axis department that stock 1 is located the pore-forming, improve the bonding effect of mud, and 5 support modes of connecting rod of this device obviously can be applicable to the pore-forming of more sizes.

2. The utility model discloses a connecting rod 5 is strutting the back, and inside two connecting rod 5 mutual articulated one ends also can be inserted to the soil layer, improve the anchor rod 1 and to the fixed effect on soil layer, can effectively avoid anchor rod 1 to deviate from in the soil layer.
