Problems solved by technology

In order to improve the durability and bearing capacity of concrete pipe piles, most of the traditional concrete pipe piles increase the amount of steel and increase the thickness of pipe piles to improve their load resistance and impermeability. This technical measure makes the pipe piles very heavy , and uneconomical, the construction cost is very high, and the more critical pipe pile has little effect on resisting high cold, high alkali and high sulfate, the maintenance cost is high during project operation, and the durability is poor

Abstract

The invention discloses a high-durability and high-bearing-capacity concrete pipe pile, which is characterized by comprising the following raw material in part by mass: 685 to 760 parts of common silicate cement, 170 to 200 parts of silicon powder with an average particle size of 0.30 mu m and a SiO2 content of more than or equal to 92 percent, 1,100 to 1,190 parts of quartz sand with a particle size between 0.16 to 1.25mm, 13 to 15 parts of superplasticizer, 165 to 190 parts of water, and 90 to 150 parts of copper-plated steel fibers with a diameter between 0.18 and 0.25mm and a length between 11 and 15mm. The preparation process of the pipe pile is to uniformly stir the steel fiber and fine quartz sand and the concrete, silicon powder, water and superplasticizer in turn to obtain a mixture, fill the mixture into a mold, form with vibrating, cure in a steam environment with a temperature between 75 and 95 DEG C and a humidity of not less than 95 percent for 36 to 48 hours and demold. The pipe pile has the advantages of high antifatigue performance and corrosion-resistance performance and small cross section thickness.

Description

technical field [0001] The invention relates to a concrete pipe pile with high durability and high bearing capacity applied to tunnels and subways and a preparation method for the pipe pile. Background technique [0002] With the rapid development of my country's economy, the construction of railways, road tunnels, and urban subways has increased rapidly, and the demand for concrete pipe piles suitable for the construction of railways, road tunnels, and urban subways has also increased. In order to improve the durability and bearing capacity of concrete pipe piles, most of the traditional concrete pipe piles increase the amount of steel and increase the thickness of pipe piles to improve their load resistance and impermeability. This technical measure makes the pipe piles very heavy , It is not economical, and the construction cost is very high. The more critical pipe pile has little effect on resisting high cold, high alkali and high sulfate, and the maintenance cost is hig...
