AI Technical Summary
Due to the empty structure of the prestressed pipe pile, it is impossible to directly use total station instruments, RTK and other measurement instruments to position it at the center of the pipe pile, resulting in inaccurate measurement of pile position and elevation.
An auxiliary tool was designed, including large hoops, small hoops, positioning steel plates, connecting steel bars and limit steel heads. These components are connected by welding to form a concentric circular structure, and overlap the center of the tool with the center of the pipe pile to achieve accurate positioning.
This tool can accurately locate the center of the prestressed pipe pile, improve the efficiency and accuracy of pile position and elevation measurement, and solve the problem of finding the center point on the pipe pile plane.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of building construction and is a tool suitable for measuring and locating the plane position and elevation of prestressed pipe piles at a construction site. Background Art
[0002] As an important form of building foundation, prestressed pipe piles are widely used in the fields of construction, bridges, etc. due to their energy conservation and environmental protection, strong bearing capacity, fast construction speed, standardized production, and conducive to ensuring project quality. Prestressed pipe piles are cylindrical in appearance due to their structural characteristics. Since the pile body is hollow, the center point of the pile top cannot be physically marked, and the center position of the pipe pile cannot be directly located when measuring with total station, RTK and other measuring instruments. Summary of the invention
[0003] The utility model provides an auxiliary tool for retesting and accepting the pile position and pile top elevation of a prestressed pipe pile.
[0004] A tool for measuring the pile position and pile top elevation of a prestressed pipe pile, which is characterized by comprising a large hoop, a small hoop, a positioning steel plate, connecting steel bars, and a limiting steel bar head. The large hoop and the small hoop are welded through the connecting steel bars and the large hoop and the small hoop are in concentric circles. The top of the small hoop is welded to the positioning steel plate, and the limiting steel bar head is welded to the bottom of the large hoop at an equal distance.
[0005] The utility model is placed on the top of the pipe pile, parallel to and fitted with the top surface of the pipe pile, and the center of the tool coincides with the center of the pipe pile to form a surveying and positioning circle center, thereby accurately locating the center of the pipe pile, which is convenient for re-measurement and collection of the coordinates and elevation of the pipe pile.
[0006] The utility model solves the problem of finding the center point of the pipe pile plane.
[0007] The utility model has the advantages of simple operation and convenient turnover, and greatly improves the efficiency and accuracy of pile position and elevation measurement. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1, Figure 2 As shown, a prestressed pipe pile position and pile top elevation measuring tool is composed of a positioning steel plate 3, a large hoop 1, a small hoop 2, a connecting steel bar 4, and a limiting steel bar head 5.
[0013] The diameter of the positioning steel plate 3 is 120 mm, and it is made of 3 mm thick steel plate. The diameter of the small hoop 2 is 100 mm, and it is made of round steel with a diameter of 10 mm. The large hoop 1 is made of round steel with a diameter of 10 mm. The connecting steel bar 4 and the limiting steel bar head 5 are both made of round steel with a diameter of 10 mm.
[0014] The positioning steel plate 3 is welded to the top of the small hoop 2. The large hoop 1 and the small hoop 2 are in the same horizontal plane and concentric circle positions, and the large hoop 1 and the small hoop 2 are welded into one with four connecting steel bars 4.
[0015] Four limiting steel bar heads 5 with a length of 30 mm are evenly arranged and welded to the bottom of the large hoop to play a clamping role.
[0016] The length of the connecting steel bars matches the diameter of the prestressed pipe piles.
[0017] The limiting steel bar head and the axis of the large hoop form an angle of 5 to 15 degrees.
