Ash scattering device for positioning and marking PHC pipe pile body

Abstract

The invention discloses an ash scattering device for positioning and marking a PHC pipe pile body. The ash scattering device for positioning and marking the PHC pipe pile body is characterized in that the ash scattering device comprises an ash containing box filled with lime, a middle connecting rod is coaxially arranged in the ash containing box, the lower part of the middle connecting rod penetrates through the bottom surface of the ash containing box and vertically extends downwards, the part, located in the ash containing box, of the middle connecting rod is a hollow pipe, and the part, located below the bottom face of the ash containing box, of the middle connecting rod is a solid rod; a piston control rod is arranged in the hollow pipe in a matched mode, a plurality of ash inlet holes are distributed in the side wall face of the middle of the hollow pipe at intervals, a circle of ash outlet holes are formed in the side wall face, located below the bottom face of the ash containing box, of the hollow pipe, each ash outlet hole communicates with an ash outlet guide pipe, and each ash outlet guide pipe is fixed to the outer side face of a variable-diameter disc frame. The ash scattering device has the advantages that the ash scattering device is simple in structure, pipe pile positioning marking operation construction is convenient and fast, and the working condition requirements of different pipe pile diameters are met.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to an ash spreading device used for positioning marks of PHC pipe piles. Background technique [0002] The pile foundation technology of prestressed high-strength concrete (PHC) pipe piles is widely used in wharf hydraulic engineering, railway bridges, factory and mine projects, especially in the construction of long-span railway bridges. Before the pile driving construction of the pipe pile, it is necessary to mark the location circle of the pipe pile according to the diameter of the pipe pile at the location point according to the location of the pile foundation along the line. At present, in the construction of pipe pile foundation positioning marks, a circular discus tool with the diameter of the pipe pile is often used to sprinkle ash along the outer edge of the discus at the positioning position of the pipe pile, thereby marking the size of the pipe pile posit...

AI Technical Summary

Problems solved by technology

However, according to different application purposes and different bearing capacities of pipe piles, the diameters of pipe piles vary, and the discus tools currently used are seriously insufficient in adaptability to working conditions; and the convenience of operation of the currently used pipe pile positioning marks is also insufficient. It is not conducive to the marking construction of pile groups
