Example Embodiment
[0019] Example 1:
[0020] Produce A-type prestressed high-strength concrete pipe piles with an outer diameter of 400mm and a wall thickness of 95mm. The materials are configured according to the following weight ratio, (cement + ground river sand): sand: stone: naphthalene superplasticizer: water: ground river sand=1: 1.58: 2.69: 0.0065: 0.28: 0.25. The specific surface area of ground river sand is 380m 2 / kg, the stone is a continuous gradation with a particle size of 5-25mm, crushing index value ≤ 7%, mud content ≤ 0.5% of the crushed stone, spread 100% of the sand to the bottom of the forced concrete mixer, and then add 100% Cement and 100% ground river sand, dry mix for 15s, add 90% of the set amount of water, mix for 30-40s, then add 100% stones and stir, add water reducing agent within 10-20s, and then according to the mix For the actual water content, add the remaining water as appropriate, stir evenly, and the total time is not less than 3.5min. Then, in the order of...

[0021] Example 2:
[0022] Produce A-type prestressed high-strength concrete pipe piles with an outer diameter of 500mm and a wall thickness of 125mm. The materials are configured according to the following weight ratio, (cement + ground river sand): sand: stone: naphthalene superplasticizer: water: ground river sand=1:1.45:2.82:0.0066:0.29:0.30. The specific surface area of ground river sand is 400m 2 / kg, the stone is a continuous gradation with a particle size of 5-25mm, crushing index value ≤ 7%, mud content ≤ 0.5% of the broken pebbles, pave 100% sand to the bottom of the forced concrete mixer, and then add 100% Cement and 100% ground river sand, dry mix for 15s, add 90% of the set amount of water, mix for 30-40s, then add 100% stones and stir, add water reducing agent within 10-20s, and then according to the mix For the actual water content, add the remaining water as appropriate, stir evenly, and the total time is not less than 3.5min. Then, in the order of the middle,...

[0023] Example 3:
[0024] Production of AB type prestressed high-strength concrete pipe piles with an outer diameter of 500mm and a wall thickness of 100mm. The materials are configured according to the following weight ratio, (cement+ground river sand): sand: stone: naphthalene superplasticizer: water: ground river sand=1:1.54:2.73:0.0065:0.29:0.40. The specific surface area of ground river sand is 380m 2 / kg, the stone is a continuous gradation with a particle size of 5-25mm, crushing index value ≤ 7%, mud content ≤ 0.5% of the crushed stone, spread 100% of the sand to the bottom of the forced concrete mixer, and then add 100% Cement and 100% ground river sand, dry mix for 15s, add 90% of the set amount of water, mix for 30-40s, then add 100% stones and stir, add water reducing agent within 10-20s, and then according to the mix For the actual water content, add the remaining water as appropriate, stir evenly, and the total time is not less than 3.5min. Then, in the order o...
