[0002] With the rapid development of highways, the number of bridges is increasing day by day. In the process of bridge construction, pile foundation is the most common structural form in bridge structure. The stability of pile foundation determines the stability of bridge, and the accuracy of pile foundation location is particularly important.

[0003] In related technologies, to obtain a stable pile foundation, a pile foundation casing is usually placed at a designated location. The stable pile foundation is then constructed inside the casing. The location of the pile foundation is determined based on its center. The calibration of the pile foundation center of the casing requires first placing a steel protective mesh on top of the casing, then erecting an auxiliary wooden board on the mesh. Surveyors stand on the auxiliary wooden board and use GPS to lay out the design center of the casing, marking it on the board. Finally, the actual deviation of the casing is calculated by the distance from the edge of the casing to the marked point. Because the inner diameter of the casing is relatively long, the auxiliary wooden board lacks guardrails, and the site environment is complex, surveyors are prone to accidents while laying out the casing on the auxiliary wooden board.

[0004] Therefore, it is necessary to design a new pile foundation casing measurement and positioning device to overcome the above problems. Utility Model Content

[0026] In this embodiment, the four ends of the fixed cross 1 are inserted into the telescopic frame 3, making the fixed cross 1 and the four telescopic frames 3 form a whole. The two connecting rods 11 are perpendicularly cross-connected, making two adjacent telescopic frames 3 perpendicular to each other, which improves the overall connection strength of the pile foundation casing measurement and positioning device. The length can be adjusted according to the size of the pile foundation casing to adapt to pile foundations of different sizes, making it convenient to store and carry. The extension direction of one section of the connecting rod 11 is the same as the extension direction of the telescopic frame 3 inserted on it, and the scale spacing of one section of the connecting rod 11 is the same as the scale spacing of the telescopic frame 3 inserted on it.

[0027] In this embodiment, by inserting the telescopic frame 3 into the four ends of the fixed cross 1, the pile foundation casing measurement and positioning device can be placed on the pile foundation casing and adapted to pile foundations of different sizes, making it convenient to store and carry. By installing the GPS receiver 2 on the fixed cross 1, the actual deviation of the pile foundation casing is recorded using the scale of the GPS receiver 2, the connecting rod 11, and the telescopic frame 3. This avoids the need for surveyors to lay out measurements on the auxiliary wooden board, solving the technical problem in related technologies where the inner diameter of the pile foundation casing is long, the auxiliary wooden board has no guardrails, and the site environment is complex, making it easy for surveyors to be in danger when laying out measurements on the auxiliary wooden board.

The pile foundation casing measurement and positioning system can be quickly assembled and the pile foundation casing deviation correction can be performed quickly, reducing the pile foundation casing correction time and ensuring the safety of the surveyor.

[0041] First, insert the four telescopic frames 3 into the fixed cross 1 and align them with the alignment line 111. Then, use the fixing bolts to pass through the fixing holes to bolt the telescopic frames 3 to the connecting rod 11. After arriving at the work site, pass the fixing screw of the GPS receiver 2 through the GPS reserved hole 12 to fix the GPS receiver 2 to the fixed cross 1.
