[0028] The utility model discloses the application of fixed block 3, clamping screw 4, adjusting disc 5, thread sleeve 6, drive rod 7 and extrusion plate 8, effectively clamp the two sides of reinforcement cage through side clamping mechanism, can limit reinforcement cage, prevent its from appearing when concrete perfusion and floating.

[0029] Embodiment two:

[0030] On the basis of embodiment one, the utility model as shown in Figure 1 And Figure 3 Disclose that the bottom fixedly connected with fixed disc 15 of injection hole cover 1 surface, the both sides of fixed disc 15 surface are all set up and are equipped with mounting hole, the top of both sides of injection hole cover 1 is fixedly connected with fixed plate 16, and the surface of fixed plate 16 is set up and is equipped with stringing hole, and the surface of adjusting disc 5 is set up and is equipped with through -hole, and both sides of counterweight cylinder 2 top are all set up and are equipped with insertion hole.

[0031] Adopt the above technical scheme, mainly is to realize the installation fixed injection hole cover 1, the purpose of convenient lifting injection hole cover 1 and fixed adjusting disc 5, will install long bolt and continue to spin into ground mounting seat and be equipped with mounting hole on the surface of fixed disc 15, reach the purpose of fixed injection hole cover 1, the end of lifting rope is passed through stringing hole and is tied, the other end of lifting rope is fixed on lifting equipment, through lifting equipment lift injection hole cover 1 and counterweight cylinder 2, the bolt is passed through the through -hole on the surface of adjusting disc 5, and continue to insert the bottom of bolt into the insertion hole in the top of counterweight cylinder 2, to this fixed adjusting disc 5, prevent its from appearing rotation because of external force.

[0032] Embodiment three:

[0033] Based on Embodiment 2, this utility model is as follows: Figures 1-2 As shown, a positioning bolt is movably connected to one side of the adjusting frame 13 and the top of the pressing plate 14. One end of the positioning bolt passes through a threaded hole on one side of the extrusion plate 8. A flange is fixedly connected to the bottom of the surface of the counterweight cylinder 2, and a counterweight ring 17 is fixedly connected to the top of the flange. An anti-slip pad is fixedly connected to the bottom of the pressing plate 14, and the bottom of the anti-slip pad is provided with anti-slip texture. An anti-slip pad is fixedly connected to the edge of the bottom of the fixed plate 15, and the bottom of the anti-slip pad is provided with anti-slip protrusions. A limit groove is opened on one side of the inner cavity of the adjusting frame 13, and a limit block is movably connected to the inner cavity of the limit groove. One side of the limit block is fixedly connected to the surface of the extrusion plate 8. An anti-slip sleeve is fitted on the edge of the surface of the adjusting plate 5. The anti-slip sleeve is made of synthetic rubber.

[0034] The above technical solution is mainly used to fix the adjustment frame 13, increase the weight of the counterweight cylinder 2, and increase the friction of the bottom of the pressure plate 14. Tightening the positioning bolt until one end is screwed into the threaded hole on one side of the extrusion plate 8 can fix the adjustment frame 13 to the surface of the extrusion plate 8, so that it will not easily loosen. The counterweight ring 17 has a large self-weight, which can further increase the weight of the counterweight cylinder 2, thereby improving the effect of preventing the steel cage from floating. The bottom of the anti-slip pad has a good anti-slip effect, which allows the pressure plate 14 to press the top of the steel cage more firmly. The anti-slip pad contacts the ground as the fixed plate 15 moves down. The anti-slip protrusions at the bottom of the anti-slip pad insert into the soil, making the fixed plate 15 more stable. The limiting block moves with the extrusion plate 8 in the limiting groove, which can improve the movement stability of the extrusion plate 8. The anti-slip sleeve can increase the friction of the surface of the adjustment plate 5 and prevent the hand from slipping when the adjustment plate 5 is turned by hand.

[0035] The working principle of this utility model is as follows: First, the injection sleeve 1 and its top counterweight cylinder 2 are installed and fixed above the pile hole, and the inner cavities of the injection sleeve 1 and the counterweight cylinder 2 are aligned with the pile hole. Then, the steel cage is placed into the inner cavity of the counterweight cylinder 2 and the injection sleeve 1, and continues to be lowered into the pile hole. The clamping screw 4 is rotated, and the clamping screw 4 drives the threaded sleeve 6 on its surface to move downward. The threaded sleeve 6 drives one end of the drive rod 7 to move downward, and the other end of the drive rod 7 drives the extrusion plate 8 to move. The two extrusion plates 8 move closer to each other to clamp the two sides of the steel cage. After the extrusion mechanism on both sides fixes the steel cage, the adjusting screw 12 is rotated by hand. When the adjusting screw 12 rotates in the threaded groove on the top of the extrusion plate 8, it will slowly move into the depth of the threaded groove. The adjusting screw 12 extrudes the adjusting frame 13 downward through the fixed sleeve on its surface. The adjusting frame 13 drives the pressing plate 14 on one side to move downward to extrude and restrict the top of the steel cage.
