The invention discloses a manufacturing method of a pumping pipe pile, and belongs to the technical field of building materials. The method comprises the steps of adding nitrite and sulfate which account for 1-2% of the mass of cement into the pump concrete, wherein the mass ratio of nitrite to sulfate is (1-2.5): 1. Nitrite and sulfate are added into the pump concrete, so that the slump of the concrete can be quickly reduced after the concrete is stirred for about 10 minutes, pumping forming is completed through filling at the moment, and it can be guaranteed that the concrete is not obviously layered during high-speed centrifugation.
本发明公开了一种泵送管桩的制造方法，属于建筑材料技术领域。包括在泵送混凝土中加入1‑2％水泥质量的亚硝酸盐和硫酸盐；所述亚硝酸盐和硫酸盐的质量比为1‑2.5:1。本发明将亚硝酸盐和硫酸盐加入泵送混凝土中，从而在混凝土搅拌好约10分钟后能够快速降低其坍落度，此时灌装已经完成泵送成型，能够保证在高速离心时不明显分层。
