Description

Technical Field

[0001] The utility model relates to the field of large-diameter bored cast-in-place pile construction, and particularly includes a standardized guide frame for steel casing sinking. Background Art

[0002] Steel casing guide frames play an important role in underground engineering, bridge construction, tunnel construction, oil drilling and other projects. These projects usually have extremely high requirements for the stability and safety of structures. The design of the steel casing guide frame enables the steel casing to maintain a stable posture and accurate verticality during the insertion process, thus avoiding the deviations and repeated adjustments that may occur in traditional insertion methods, and then ensuring the smooth progress and final quality of the project.

[0003] However, the currently used guide frame bodies are generally relatively simple. For the steel casings of large-diameter bored cast-in-place piles, it is difficult to ensure the stability of the frame body itself during the sinking process, and it is easy to tip over laterally. Moreover, there are few devices on the current guide frame for adjusting the plane position of the steel casing, and it is difficult to accurately adjust the position of the steel casing in a short time.

[0004] In view of this, in view of a series of problems existing in the use of guide frames in the current steel casing sinking construction of large-diameter bored cast-in-place piles, it is urgent to invent a simple and effective standardized guide frame for steel casing sinking to effectively control the insertion position and verticality of the steel casing, thereby improving construction efficiency, ensuring project quality and reducing construction costs.

The upper unit of the guide frame and the lower unit of the guide frame are fixedly connected through upper and lower unit connecting steel sections, and the open-front truss is installed on the open side of the guide frame;

[0007] The steel casing vertically penetrates the space enclosed by the open-front truss and the arc-shaped cross beam. Adjusting jacks are provided inside both the open-front truss and the arc-shaped cross beam for propping up the steel casing.

[0008] Preferably, the steel casing is placed at the central position of the guide frame. Guide frame columns are respectively arranged at both ends of the open side of the guide frame.
