Super-long prefabricated large tubular pile, and preparation method and application of super-long prefabricated large tubular pile
The invention belongs to the technical field of concrete steel pipe piles, and particularly provides an ultra-long prefabricated large pipe pile, a preparation method of the ultra-long prefabricated large pipe pile and application of the ultra-long prefabricated large pipe pile. The ultra-long prefabricated large pipe pile comprises pipe joint raw materials which comprise C70 dry hard concrete and a reinforcement cage; the C70 dry hard concrete comprises water, cement, sand, aggregate and an additive, according to the grouting material in pipe joint splicing, the grouting material comprises cement, an additive, an expanding agent and water, and the grouting material is an M50 grouting material. In the invention, the original C60 grade concrete and M40 grouting material are respectively improved to C70 grade concrete and M50 grouting material, so that the comprehensive performances such as the hammering resistance and the bending resistance of the prefabricated large pipe pile are improved.
本发明属于混凝土钢管桩技术领域，具体提供了超长预制大管桩、超长预制大管桩的制备方法及应用本发明中，超长预制大管桩，包括以下原料：管节原料，所述管节原料包括C70干硬性混凝土和钢筋笼，所述C70干硬性混凝土包括水、水泥、砂、骨料以及外加剂；管节拼接中的灌浆料，所述灌浆料包括水泥、外加剂、膨胀剂以及水，所述灌浆料为M50灌浆料。本发明中，将原C60等级混凝土和M40灌浆料分别提高到C70等级混凝土和M50灌浆料，以提高预制大管桩的抗锤击性能和大管桩的抗弯能力等综合性能。
