High-strength prefabricated reinforced concrete hollow square pile
The invention discloses a high-strength prefabricated reinforced concrete hollow square pile comprising an upper-segment pile and a lower-segment pile, and a grouting hole is formed in the center of each of the upper-segment pile and the lower-segment pile; the hollow square pile is characterized in that the upper-segment pile and the lower-segment pile each comprise the following raw materials in parts by weight: 3 parts of basalt fibers, 2 parts of steel fibers, 4 parts of glass fibers, 100 parts of cement, 90 parts of fly ash, 900 parts of gravels with the particle size of 10-15 mm, 200 parts of gravels with the particle size of 15-20 mm, 800 parts of sand, 130 parts of water, 1.5 parts of an amino-sulfonate high-efficiency water-reducing agent, 10 parts of bentonite, 0.5 part of a super plasticizer, 1 part of an air entraining agent, 0.1 part of a defoaming agent, 0.2 part of a rosin soap, 0.05 part of a tackifier, and 0.3 part of calcium stearate. The high-strength prefabricated reinforced concrete hollow square pile has higher single-pile bearing capacity, and has the strength improved by 50% or more compared with concrete of the prior art.
