Abstract

The invention discloses a corrosion-resistant cement pipe pile for photovoltaics and a preparation method thereof. The preparation method comprises the following steps of: firstly preparing raw materials, and weighing the raw materials of each component according to a certain ratio; putting an admixture into a ball mill for ball milling, and sieving by using a 200-micrometer sieve to obtain admixture powder, wherein the ball milling time is 3 hours; then preparing preservative oil; afterwards, synthesizing a water-reducing composition, to be specific, firstly synthesizing first reaction liquid, then synthesizing second reaction liquid, and carrying out cold pressing sintering to obtain the water-reducing composition; and finally preparing the cement pipe pile, removing a mold, placing thecement pipe pile in the air, obtaining the finished product after standing for a period of time, and carrying out quality test. The corrosion-resistant cement pipe pile for photovoltaics and the preparation method thereof provided by the invention have the beneficial effects that the proportion and reaction time are reasonably controlled in the preparation process; the corrosion resistance and heat resistance of the prepared cement pipe pile are effectively improved, and meanwhile the improvement of the water-reducing composition also reduces the weight of cement; the cost is greatly saved; and the corrosion-resistant cement pipe pile has very high practicability.

Description

technical field [0001] The invention relates to the field of pipe pile manufacturing, in particular to a photovoltaic corrosion-resistant cement pipe pile and a preparation method thereof. Background technique [0002] Pipe piles are divided into post-tensioned prestressed pipe piles and pretensioned prestressed pipe piles, prestressed concrete pipe piles (PC pipe piles), prestressed concrete thin-walled pipe piles (PTC pipe piles) and high-strength prestressed pipe piles Stressed concrete pipe piles (PHC pipe piles) are mostly used in the market today to prepare concrete and manufacture pipe piles. [0003] Most of the prestressed concrete piles on the market today have the characteristics of high single pile bearing capacity, low price, good bending resistance, small settlement, stable and reliable quality, and fast construction speed. They have been widely used in industrial buildings, civil buildings and Basic engineering such as bridges and ports. [0004] However, wi...
