Photovoltaic anti-cracking cement pipe pile and preparation method thereof

Abstract

The invention discloses a photovoltaic anti-cracking cement pipe pile and a preparation method thereof. The anti-cracking cement pipe pile is prepared from the following components: an aggregate, cement, an admixture, an additive, an anti-cracking component and water. The preparation method of the cement pipe pile comprises the steps of weighing the aggregate and the admixture, stirring, and uniformly mixing to obtain a first mixture; weighing the cement and the additive, adding water, stirring, and uniformly mixing to obtain a second mixture; adding the first mixture into the second mixture,stirring, and uniformly mixing to obtain concrete; putting the concrete into a mold, stretching and drawing, and centrifugally forming obtain a concrete pipe pile semi-finished product; maintaining the concrete pipe pile semi-finished product, demolding, and naturally maintaining to obtain a concrete pipe pile finished product. The experiment result shows that the prepared concrete pipe pile has an excellent anti-cracking ability.

Description

technical field [0001] The invention relates to the technical field of photovoltaics, in particular to a crack-resistant cement pipe pile for photovoltaics and a preparation method thereof. Background technique [0002] In recent years, the photovoltaic industry has developed rapidly. So far, my country's total installed photovoltaic capacity has exceeded 100GW. According to the development plan of my country's photovoltaic industry, it will still maintain a relatively rapid development speed in the future. The largest proportion of civil engineering in photovoltaic projects is photovoltaic support and foundation engineering. Common photovoltaic support foundations include reinforced concrete independent foundations, strip foundations, micro-cast-in-situ pile foundations, high-strength prestressed pipe pile foundations, and steel screw pile foundations. etc. At present, the most commonly used pile foundations for photovoltaic power stations in the market are high-strength p...

AI Technical Summary

Problems solved by technology

At present, the most commonly used photovoltaic power plant pipe pile foundations in the market are high-strength prestressed pipe pile foundations and steel screw pile foundations. Among them, high-strength prestressed pipe pile foundations have the advantage of good construction flexibility, but they have the disadvantage of concrete pouring and tamping. It is not dense and easy to crack, which leads to the problem of poor pile quality. The steel screw pile foundation has the advantages of light weight and convenient construction. However, the steel screw pile foundation has the problems of high cost and low bearing capacity. Therefore, it is necessary to develop a A concrete pipe pile with good crack resistance and good pile quality
