Description

Pile foundation construction resumes location frock and system Technical Field The utility model relates to the technical field of bridge building engineering, in particular to a pile foundation construction restoration positioning tool and system. Background Pile foundations are the most common foundation forms in bridge, building and other projects, and the construction quality directly influences the stability and safety of the integral structure. The bored pile is widely used because of the characteristics of strong adaptability, high bearing capacity and the like, and the pile position deviation is used as one of key quality indexes and needs to be strictly controlled within a design allowable range. In the construction process, a mode of arranging riding piles at the periphery of a pile position is generally adopted, and the center position of the pile is recovered and rechecked through the crossed positioning of stay wires. However, the prior art suffers from the following significant drawbacks: The precision is not enough, the traditional riding pile relies on manual stay wire positioning, positioning errors are accumulated easily due to inaccurate perpendicularity adjustment and stay wire height deviation, and the high-precision construction requirement is difficult to meet. Poor stability, in which the riding pile is easy to displace or incline due to mechanical vibration, soil disturbance and the like of a construction site, and the state change of the device cannot be monitored in real time, so that the pile position recovery reliability is reduced. The fixing mode is single (for example, the fixing mode is only fixed through steel nails), the installation stability is not enough under the condition of different fields such as soft soil, concrete and the like, and the leveling and fine tuning functions are not convenient and fast. The problems not only affect the construction efficiency, but also may cause reworking, cost increase and even potential safety hazard. Therefore, a novel pile foundation construction restoration positioning tool is needed to solve the defects in the prior art and improve construction quality and efficiency. Disclosure of utility model The utility model provides a pile foundation construction restoration positioning tool and a system, which adopt the following technical scheme that the pile foundation construction restoration positioning tool comprises: The chassis is in a triangular structure, the edge of the chassis is provided with a fixing lug, and the fixing lug is provided with a round hole for fixing a steel nail or an expansion screw; The top plate is a triangular steel plate and is connected with the chassis through a vertical rod, and a fine-adjustment stroke space hole is formed in the top plate; The lower ends of the three vertical rods are welded at the triangular vertex position of the chassis, and the upper ends of the three vertical rods are provided with screws and fixedly connected with the top plate through nuts and locking nuts; The inclined strut is welded between the adjacent vertical rods; the positioning rod is vertically arranged on the fine adjustment stroke space hole of the top disc through a positioning rod nut and a positioning rod lock nut. Furthermore, the recovery positioning tool is also provided with two level bars which are mutually perpendicular to the surface of the top disc. Further, the included angle between the inclined stay bar and the vertical rod is 30-60 degrees, and the inclined stay bar and the vertical rod are welded and connected to form a triangular supporting structure.
