Technical Field
[0001] The utility model belongs to the field of building construction, and particularly relates to a simple device for spraying white lime lines on the edges of prefabricated pipe piles. Background Art
[0002] During the construction preparation of precast pipe piles, whether it is hammer-driven piles or static pile pressure, the center line and edge line of the precast pipe piles must be accurately located to ensure accurate positioning of the pile foundation, thereby ensuring that the allowable deviation of the pile position of the precast pipe piles meets the requirements of the specifications.
[0003] In the traditional layout process, the center point of the precast pipe pile is relatively easy to locate, but the white lime line of the precast pipe pile edge is difficult to sprinkle. The currently commonly used method of spraying with a round plastic bucket cover is difficult to ensure the center point is aligned, and the round plastic bucket cover is easy to deform and lose, and the spraying efficiency is low, which can easily cause large deviations.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and the best embodiment.
[0020] Figure 1-2 A simple device for spraying white lime lines on the edges of prefabricated pipe piles is shown, comprising an inner tube 1, a lower plate 4 connected to the inner tube, an outer tube 2, and an upper plate 3 connected to the outer tube; the inner tube 1 is rotatably connected to the outer tube 2; and openings 6 are provided on both the upper plate 3 and the lower plate 4.
[0021] The upper plate 3 is provided with a steel plate edge 5; as one embodiment, the height of the steel plate edge is 10 cm.
[0022] The opening position of the lower plate 4 is arranged corresponding to the outer edge position of the pipe pile.
[0023] The inner tube 1 and the outer tube 2 are rotatably connected via a bearing.
[0024] A conical positioning head 7 is provided at the bottom of the inner tube 1 .
[0025] Both the inner tube 1 and the outer tube 2 are provided with handles 8 .
[0026] The thickness of the upper plate 1 and the lower plate 2 is 10 mm.
[0027] There are 16 openings 4; the diameter of the openings is 10 mm.
[0028] As an implementation form of the present application, the utility model provides a simple device for spraying white lime lines on the edges of prefabricated pipe piles, which consists of two circular steel plates with multiple holes (upper plate and lower plate), a steel drill positioning head, an inner tube, an outer tube, a bearing connecting the inner tube and the outer tube, and two external handles.
[0029] The two circular steel plates (upper and lower plates) should be 10mm thick. The central opening of the upper plate is connected to the lower plate via an inner tube, and the inner tube is connected to the upper plate and the outer tube. The position of the openings on the edge of the lower plate is determined by the diameter of the prefabricated pipe pile. For example, if it is designed to be 400mm, the distance from the center point of the opening on the edge of the circular steel plate of the lower plate to the center point of the circular steel plate is 400mm. The diameter of the opening should be 10mm, and the number of openings should be 16, with the two steel plates connected vertically.
[0030] Before operation, the two steel plates are rotated to stagger the holes. A 10cm high steel plate edge is welded around the perimeter of the upper steel plate (upper plate) to store the lime. The locating head at the top of the outer pipe is welded to the center hole of the lower steel plate (lower plate) to align with the center point of the prefabricated pile.
[0031] The outer tube and the inner tube are both connected to the handle 8. When in use, first position the (steel chisel) positioning head on the center point of the prefabricated pipe pile, then rotate the handle connected to the outer tube to drive the upper steel plate (upper disk) to rotate. When the holes on the edges of the upper and lower steel plates (upper and lower disks) are aligned, the white ash on the upper steel plate (upper disk) is automatically sprayed onto the ground along the hole position, forming a white ash line on the edge of the prefabricated pipe pile.
[0032] In summary, ① the present invention's white lime line spraying device for prefabricated pipe pile edges has a simple structure, is easy and safe to operate, allows quick familiarization by workers, and achieves high construction efficiency. ② The present invention's white lime line spraying device for prefabricated pipe pile edges is easy and convenient to install and disassemble, and the materials used are convenient to rent, transport, and store, resulting in low investment costs and good economic benefits. ③ The present invention's white lime line spraying device for prefabricated pipe pile edges solves the technical problem of quickly and accurately spraying white lime lines on prefabricated pipe pile edges, ensuring the position deviation of prefabricated pipe piles.

For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
