Description
Technical Field
[0001] The utility model relates to the technical field of bridge engineering, and particularly relates to a positioning and protection device for the steel cage of a bridge bored cast-in-place pile. Background Technique
[0002] The positioning and protection device for the steel cage of a bridge bored cast-in-place pile is a tool or device specifically used for accurately positioning and effectively protecting the steel cage of a bored cast-in-place pile during bridge construction, ensuring that the steel cage is in the designed position in the bored cast-in-place pile hole and guaranteeing the accuracy of its verticality and horizontal position. For example, in the foundation construction of some large bridges, if the positioning of the steel cage is inaccurate, it may lead to uneven stress on the pile body, affecting the overall stability of the bridge.
[0003] Currently, in engineering, discarded steel bars are welded to control the thickness of the steel bar protection layer. Firstly, it is not convenient to erect the formwork, and secondly, the rust prevention treatment is inconvenient.
[0004] The existing patent (publication number: CN214575151U) discloses a steel bar protection device for bored cast-in-place piles, including a fixing strip and a device body. The fixing strip is inserted into the device body. The fixing strip is a steel bar strip, which can fix the position of the steel cage, effectively prevent the steel cage from sinking into the soft soil layer, ensure that the steel cage is always located at the center of the pile body, and the thickness of the protection layer is uniform.
[0005] In view of the above problems, the existing patent gives a solution. However, the existing positioning and protection device for the steel cage of a bridge bored cast-in-place pile is prone to positioning deviation during use. In areas with complex geological conditions, local deformation may occur in the pile hole, making it impossible for the positioning and protection device to accurately maintain the position of the steel cage. Moreover, most positioning and protection devices are not convenient for positioning adjustment work. In actual operation, the adjustment mechanism of some adjustable positioning and protection devices is prone to problems such as jamming and inflexibility, resulting in the inability to accurately adjust to the required position.
[0006] Therefore, a positioning and protection device for the steel cage of a bridge bored cast-in-place pile is proposed. Content of the Utility Model
