Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation construction, in particular to an auxiliary positioning device for lowering a reinforcement cage in pile foundation construction. Background Art

[0002] With the increasing number of bridge engineering projects, the demands on construction technology are becoming increasingly demanding. In areas with particularly complex geological conditions, particularly karst regions, bridge pile foundation construction places high demands on pile quality. The presence of karst caves in these special strata significantly increases the difficulty and complexity of drilling. Frequent mechanical drilling often leads to unstable borehole walls, resulting in collapse and irregular shapes, which in turn poses a significant challenge to the verticality of the subsequent lowering of the rebar cage. Traditionally, cage cover spacers have been added to the rebar cage to stabilize the position of the rebar, ensure the required cover thickness, and prevent damage. However, in practice, relying solely on cover spacers is still difficult to control the verticality of the cage lowering process. This is especially true for the lowering of the rebar cage in ultra-deep pile foundations, where multiple bolt connections are required throughout the entire process, significantly impacting the cage's lowering. The verticality of the cage's lowering directly affects the overall quality and safety of the pile foundation. Therefore, exploring more efficient and accurate auxiliary positioning technologies is crucial. Utility Model Content

In addition, the fixed frame 1 provided can be used to fix the steel cage, facilitate the steel cage connection work, and have better stability.

[0026] In this embodiment, please refer to Figure 1 A limit adjustment assembly is provided between the mounting platform 2 and the casing 6. The limit adjustment assembly includes a limit support 4 and a limit adjustment screw 5. The limit support 4 is fixedly mounted on the bottom of the mounting platform 2, and the limit adjustment screw 5 is mounted on the limit support 4. By rotating the limit adjustment screw 5, the position of the mounting platform 2 can be adjusted to ensure that the entire device and the steel casing 6 are in a concentric circle position. This can ensure that the steel cage is aligned with the center line of the pile hole when lowered, thereby ensuring the verticality and positioning accuracy of the steel cage.

[0027] In this embodiment, please refer to Figure 1 The number of the limit adjustment components is multiple, and each limit adjustment component is evenly spaced between the mounting platform 2 and the casing 6. Optionally, the number of the limit adjustment components is three, and the three limit adjustment components are distributed at an angle of 120 degrees, which is used for limit fixed adjustment, thereby increasing construction stability and positioning accuracy, and making construction operation more convenient.

[0028] In this embodiment, please refer to Figure 1 and Figure 2The position adjustment assembly 8 includes a position adjustment fixed support 3, a position adjustment drive 10, a position adjustment mounting frame 12 and a position adjustment rod 11; the position adjustment fixed support 3 is installed on the mounting platform 2, the position adjustment drive 10 and the position adjustment mounting frame 12 are installed on the position adjustment fixed support 3, the position adjustment rod 11 is installed on the position adjustment mounting frame 12, one end of the position adjustment rod 11 is transmission-connected to the position adjustment drive 10, and the other end of the position adjustment rod 11 is connected to the positioning plate 7.

Optionally, the position adjustment drive member 10 is provided with an adjustment switch 9 for starting and stopping the position adjustment drive member 10 .

[0029] In this embodiment, the position adjustment driving member 10 is a driving motor, and the position adjustment rod 11 is a telescopic adjustment rod.

[0030] In this embodiment, the position adjustment driving member 10 may also be a hydraulic cylinder, and the position adjustment rod 11 is a push rod.

[0031] In this embodiment, please refer to Figure 2 The position adjustment rod 11 is provided with scale lines along its length. Providing scale lines on the position adjustment rod 11 can firstly achieve precise positioning. Through the scale lines, construction personnel can intuitively understand the adjustment length of the position adjustment rod 11, thereby accurately controlling the distance between the positioning plates 7, ensuring that steel cages of different diameters can be accurately positioned and assisted, thereby improving construction accuracy.

Thirdly, it can facilitate recording and adjustment. During the construction process, the scales of the position adjustment rod 11 corresponding to steel cages of different diameters can be recorded, which is convenient for reference and adjustment in subsequent construction.

[0032] In this embodiment, please refer to Figure 1The positioning plate 7 is an arc-shaped annular plate structure. The purpose of the positioning plate 7 being set as an arc-shaped annular plate structure is, firstly, to reduce the friction with the steel cage, making it easier to slide, thereby guiding the steel cage to be lowered more smoothly. This is particularly important for ultra-deep pile foundation construction, and can effectively reduce the construction difficulty and labor intensity; secondly, it can effectively prevent the steel cage from deforming. The annular design can avoid direct contact between the steel cage and the positioning plate 7 during the vertical lowering process, reducing collision and friction, thereby preventing the steel cage from deforming or being damaged; finally, the arc surface design of the positioning plate 7 can increase the force-bearing area of ​​the positioning plate 7 in contact with the steel cage, disperse the pressure, reduce single-point force, and thus improve safety performance.

[0033] In this embodiment, the positioning plate 7 is made of steel plate. The selection of steel plate not only has high strength, capable of withstanding gravity and impact during the lowering of the steel cage, ensuring the stability and safety of the device, but also has high wear resistance, which can resist friction and collision during the lowering of the steel cage, thereby extending the service life of the device.

[0034] In this embodiment, please refer to Figure 1 The adjustment modules are evenly distributed around the mounting platform 2, and the spacing angles and distances between the modules are evenly distributed. The even spacing of the adjustment modules effectively improves the stability and adjustment range between the positioning plates 7, reduces stress concentration, ensures the stability and reliability of the device, and thus improves the efficiency and safety of pile foundation construction.

[0035] In this embodiment, please refer to Figure 1 , the fixed frame 1 includes a plurality of fixed rods, and each of the fixed rods overlaps and cooperates with each other. The fixed frame 1 set up has the following advantages. First, the fixed frame 1 formed by the combination of multiple fixed rods can provide a larger support area, enhance the stability of the device, and avoid shaking or tilting during the lowering of the steel cage. This is particularly important for ultra-deep pile foundation construction, and can effectively ensure the verticality of the steel cage and improve the quality of the pile foundation. Secondly, the fixed frame 1 formed by the combination of multiple fixed rods can provide more connection points, which is convenient for construction personnel to connect the steel cage and ensure that the connection is firm and reliable. This can effectively improve construction efficiency and reduce safety hazards. Secondly, the fixed frame 1 can be adjusted according to the diameter of the steel cage to adapt to steel cages of different sizes, thereby improving the applicability and flexibility of the device. This can be adjusted according to actual construction needs, avoiding frequent replacement of the device and improving construction efficiency. Finally, the fixed frame 1 formed by the combination of multiple fixed rods can increase the force-bearing area in contact with the steel cage, disperse the pressure, reduce single-point force, and thus improve safety performance.
