Description

Technical Field

[0002] In construction projects, bored cast-in-place piles are a common foundation treatment method and are widely used in various foundation projects. The principle is to drill holes in the stratum and lower the steel cage, which is a structure used to support and protect the pile body. It is usually made of welded steel bars, and then the pile body is formed by pouring concrete or mortar in the hole. This type of pile can provide good bearing capacity and stability and is suitable for various geological conditions and engineering requirements.

[0003] For example, the Chinese patent number is: CN215888211U. The utility model relates to a bored pile, including a casing, a mounting seat is fixedly connected to the bottom end of the casing, a steel cage is connected inside the casing, the steel cage includes an outer connecting rod and a first reinforcing ring, the first reinforcing ring is equidistantly arranged on the inner side of the outer connecting rod, the outer connecting rod is annularly equidistantly arranged on the outer side of the first reinforcing ring, and the first reinforcing rod is fixedly connected between the outer connecting rods to increase the strength of the outer connecting rod and the first reinforcing ring, avoid deformation caused by pressure during pouring, and avoid deformation caused by the pressure of concrete solidification on the outer connecting rod and the first reinforcing ring during pouring.

[0004] In the event of deformation and fracture, the positioning rod can be effectively protected from deformation during the insertion and positioning process. During the installation of the casing, the casing can be quickly positioned inside the pile hole, which can further improve the stability of the assembly of the steel cage inside the casing.

[0005] The above patent still has certain defects. This patent can further improve the stability of the assembly of the steel cage inside the casing, and place the tubular reinforcement device end to end and place it inside the bored pile to reinforce the pile hole. Although this structure can reinforce the pile wall, it has poor stability and is easily affected by factors such as water flow, which may cause the pipe mouth to tilt. Once the pipe mouth tilts to the lower side, even if there is no deviation during the pouring process, the entire bored pile will eventually be crooked. Utility Model Content

[0037] See also Figure 3In order to connect the mounting plate 3, the connecting mechanism 4 in this embodiment includes two positioning blocks 401, two threaded rods 402, two movable plates 403, two rotating plates 404, two stoppers 405 and two fixed blocks 406.

[0040] The working principle of the above embodiment is:

[0041] (1) When the pipe mouth needs to be fixed by the stabilizing mechanism 2, the locking nut 202 is loosened so that the fixing bolt 211 can be rotated. Then, the fixing bolt 211 is rotated two circles to loosen the limit block 203, and the auxiliary plate 205 is rotated to make the drill rod 207 disengage from the fixing plate 206. Then, the fixing plate 206 is made to fit with the ground. Then, the drill rod 207 is inserted into the ground through the first threaded hole on the fixing plate 206 and the auxiliary plate 205 is rotated to allow the drill rod 207 to enter the ground. After the auxiliary plate 205 and the fixing plate 206 are fitted, the auxiliary plate 205 is stopped from being rotated. Then, The fixing bolt 211 is rotated so that the nut of the fixing bolt 211 fits with the stabilizing rod 209 to lock the limit block 203, and then the locking nut 202 is rotated to lock the fixing bolt 211 to prevent it from rotating. The stabilizing mechanism 2 supports the left and right sides of the pipe mouth through the cooperation of the first articulated frame 201, the second articulated frame 204, the auxiliary plate 205, the fixing plate 206, the drill rod 207, the support plate 208, the stabilizing rod 209 and the extension rod 210, so that the pipe mouth cannot move, thereby preventing the pipe mouth from being deviated and skewed under the impact of the water flow, thereby ensuring the quality of the cast-in-place pile after formation.

[0042] (2) After the concrete is poured into the casing 1 and the bored pile is formed, the two rotating plates 404 are rotated. While the rotating plates 404 rotate, the threaded rod 402 is driven to rotate together through the stopper 405. The movable plate 403 moves toward the outside of the mounting plate 3 as the threaded rod 402 rotates, and drives the fixing block 406 to gradually disengage from the fixing groove. When the fixing block 406 is completely out of the fixing groove, the mounting plate 3 is lifted upward, and the positioning block 401 can be driven to move upward together until it is out of the casing 1, thereby removing the stabilizing mechanism 2. The connecting mechanism 4 facilitates the staff to install or remove the mounting plate 3 through the cooperation of the positioning block 401, the threaded rod 402, the movable plate 403, the rotating plate 404, the stopper 405 and the fixing block 406, thereby fixing the stabilizing mechanism 2 or removing the stabilizing mechanism 2, so that the stabilizing mechanism 2 can be reused, thereby reducing the use cost and improving practicality.
