High friction uplift-resistant concrete tubular pile and preparation method thereof
The present invention discloses a high friction uplift-resistant concrete tubular pile. According to the present invention, with doping of the ethoxylated rubber, the internal pore structure of concrete can be effectively improved and a large number of closed pores are formed, such that the capillary pores can be prevented from formation of the continuous and penetrating network structure system, the anti-carbonation zone can be formed, and the further enhancement effect is provided for the inhibition of the intrusion of carbon dioxide; and the contents of the harmful pores and the defects in the concrete structure can be effectively reduced, the alkality of the hydration product is reduced, and the conversion of the low strength hydration product to the high strength hydration product is promoted.
