Tubular pile and preparation method thereof
The invention discloses a preparation method of a tubular pile. The preparation method includes the following steps of mixing and stirring concrete materials to form pile body concrete, arranging the stirred pile body concrete in a mold for prestress tension, conducting centrifugation on the pile body concrete on which prestress tension is conducted till the tubular pile is formed, detaching the mold, and conducting natural curing to obtain the prestress high-strength concrete tubular pile. The concrete raw materials contain super high-early strength polycarboxylate superplasticizer which is the compound shown as the formula (1) or (2). The preparation method of the tubular pile has the advantages of being easy to operate, safe in production and low in cost. The prepared tubular pile is smooth in inner wall, thin in mortar layer and not prone to softening pulp, demolding can be conducted within 7-10 hours, and the tubular pile can reach the factory strength within 3-5 days.
