[0002] In the pipe pile production process, demoulding is a very key link. The pipe pile is usually made in a special mould through a series of processes such as pouring concrete and centrifugal forming. When the pipe pile is preliminarily formed in the mould and reaches a certain strength, demoulding operation needs to be carried out, and whether the demoulding is successful or not directly affects the quality and production efficiency of the pipe pile. If the demoulding is improper, cracks and pitted surface defects may occur on the surface of the pipe pile, and the structural strength and durability thereof are reduced.

[0003] However, the traditional process has significant defects. First, the function of removing dust and impurities on the inner wall of the pipe pile mould before spraying the demoulding agent is lacking, which leads to uneven adhesion of the demoulding agent, insufficient adhesion, reduced demoulding efficiency and pipe pile surface quality. In addition, the spraying automation is insufficient, and the fixed spray head or handheld operation cannot fully cover the inner wall of the mould, which is prone to uneven spraying or omission. Manual operation has high labor intensity, cannot meet the needs of mass production, and leads to low efficiency and high cost. SUMMARY
