[0032] Reference drawings Figure 1-3 The anchor base 100 includes an anti-pullout anchor 110, a panel 120 and a clamp 130. The panel 120 is provided with an arc groove 121, and the arc grooves 121 on several panels 120 are assembled into a grouting hole 400; the clamp 130 is located at the splicing position of the panel 120 and is used to fix adjacent panels 120; the anti-pullout anchor 110 is fixedly connected to the panel 120, and its bottom end is provided with an anchor cone 111 and an anti-pullout cone 112. The anti-pullout cone 112 is evenly distributed around the circumference of the anchor cone 111. The tip of the anchor cone 111 faces downward and can fix the panel 120 when it is inserted into the foundation. The tip of the anti-pullout cone 112 faces horizontally or obliquely upward and is used to resist the floating phenomenon of the anti-floating anchor rod during the pile hole pouring, thereby preventing the anchor base 100 from loosening and moving upward, thereby causing the anti-floating anchor rod to be dislocated.
[0033] The number of panels 120 and the shape of the arcuate grooves 121 can be configured according to specific needs. For example, in this embodiment, to facilitate installation and disassembly, two panels 120 are constructed, and semicircular arcuate grooves 121 are excavated on opposite sides of the two panels 120. The two semicircular arcuate grooves 121 are combined to form a circular grouting hole 400 for grouting the pile hole. The clamp 130 is constructed to include a C-shaped block 131 and a locking bolt 132. The joint of the two panels 120 extends into the C-shaped block 131. The locking bolt 132 vertically penetrates the top plate of the C-shaped block 131, the panel 120, and the bottom plate of the C-shaped block 131, and then locks. To ensure connection stability, at least one locking bolt 132 is provided on each side of the joint between the two panels 120.
[0034] Reference Attachment Figure 4-6 The anti-pullout anchor 110 also includes an outer sleeve 113, an operating rod 114, a limiting support block 115, a limiting pressure block 116 and a mounting block 117. The operating rod 114 is movably inserted into the outer sleeve 113 and is threadedly connected to the internal threaded sleeve 119 at the top of the outer sleeve 113; the limiting support block 115 is fixedly arranged at the bottom end of the operating rod 114; the mounting block 117 is located above the limiting support block 115 and movably sleeved on the operating rod 114; the limiting pressure block 116 is located above the mounting block 117 and is fixedly connected to the operating rod 114; a retracting hole 113a is opened on the side wall of the outer sleeve 113, and a horizontal rotating shaft 118 is provided on the mounting block 117. The blunt end of the anti-pullout cone 112 is rotatably connected to the horizontal rotating shaft 118, and the tip of the anti-pullout cone 112 at least partially extends out of the retracting hole 113a. The anchor cone 111 is arranged at the bottom of the outer sleeve 113 and can be welded or integrally formed with the outer sleeve 113. The anchor cone 111 can be completely solid, or the blunt end (i.e., the top) is partially hollow and connected to the inner cavity of the outer sleeve 113, and the retracting hole 113a is adaptively constructed on the side wall of the hollow part of the top of the anchor cone 111. It can be constructed according to actual needs and no more specific restrictions are given here.
[0035] When the operating rod 114 is rotated to lift the limiting support block 115, the mounting block 117 moves upward. Due to the pressure from the top wall of the retracting hole 113a and the lifting force from the mounting block 117, the blunt end of the anti-extraction cone 112 rotates around the horizontal rotation axis 118, and its tip also gradually rotates and slides further outside the retracting hole 113a, producing an anti-extraction effect; when installing or removing the anti-extraction anchor 110 in the foundation, the operating rod 114 is rotated in the opposite direction to lower the limiting support block 115, and the limiting pressure block 116 moves downward accordingly, generating downward pressure on the mounting block 117, driving the mounting block 117 to move downward, and the blunt end of the anti-extraction cone 112 rotates in the opposite direction around the horizontal rotation axis 118, and its tip also gradually rotates in the opposite direction and retracts more into the retracting hole 113a, making the outer wall of the outer sleeve 113 gradually smooth, making it easier to penetrate into or be extracted from the foundation.

The flange nuts 210 at both ends of the anchor rod mounting hole 500 are sleeved on the anti-floating anchor rod, and the second panel 220 and the anti-floating anchor rod are fixed by the pressing action with the top and bottom surfaces of the second panel 220. This can not only improve the installation efficiency, but also ensure the locking effect and the elevation accuracy of the anti-floating anchor rod.
[0037] The number of the above-mentioned panels 220 and the shape of the arc-shaped grooves 221 can be configured according to specific needs. For example, in this embodiment, to facilitate installation and disassembly, two panels 220 are constructed, and semicircular arc-shaped grooves 221 are dug on the opposite sides of the two panels 220. The two semicircular arc-shaped grooves 221 are combined to form a circular anchor rod installation hole 500 for installing an anti-floating anchor rod. The clamp 230 is constructed to include a C-shaped block 231 and a locking bolt 232. The joint of the two panels 220 extends into the C-shaped block 231. The locking bolt 232 vertically penetrates the top plate of the C-shaped block 231, the panel 220, and the bottom plate of the C-shaped block 231, and then locks. To ensure the stability of the connection, at least one locking bolt 232 is provided on each side of the joint between the two panels 220.

The evenly distributed adjustment arms 300 ensure the coaxiality of the grouting hole 400 and the anchor rod mounting hole 500. The length of the turnbuckles is adjustable. By adjusting the length of each turnbuckle, the height of the anchor rod mounting plate 200 and the anti-floating anchor rod can be changed to meet construction requirements. If necessary, a spirit level can be placed on the second puzzle piece 220. When changing the length of each adjustment arm 300, the verticality of the anti-floating anchor rod can be judged by observing the spirit level.
[0039] Adaptively, a plurality of vertical ear plates 600 corresponding to the adjusting arm 300 may be provided on the top surface of the anchor base 100, and a plurality of horizontal ear plates 700 corresponding to the adjusting arm 300 may be provided on the side of the anchor rod mounting plate 200.

[0040] Compared with existing technologies, the present invention has the following advantages: not only can the device accurately adjust the anti-floating anchor rod to a preset elevation before pouring the pile hole, but it can also fix the anti-floating anchor rod during the pouring and curing process to prevent it from floating or shifting. This ensures the accuracy of the actual elevation of the anti-floating anchor rod after construction, reducing the problems of traditional technologies such as the need for secondary processing and the purchase of special extension screws and matching sleeves due to inconsistent elevations of the anti-floating anchor rod after construction. This improves construction efficiency and quality, and reduces construction costs. Furthermore, the present device can be repeatedly installed and disassembled and used in a turnover manner, improving construction economics.
