Secondary normal-pressure steam-cured tubular pile concrete and tubular pile production process
The invention discloses secondary normal-pressure steam-cured pipe pile concrete and a pipe pile production process. The concrete is prepared from the following components in parts by mass: 1320 to 1450 parts of gravel, 650 to 780 parts of sand, 360 to 480 parts of cement, 60 to 100 parts of microbead powder, 30 to 100 parts of water and 10 to 16 parts of a water reducing agent. The tubular pile is hoisted to a steam curing pool for first-time normal-pressure steam curing after centrifugal dewatering forming, demolding is conducted after first-time normal-pressure steam curing is conducted, and then the tubular pile is hoisted to the steam curing pool for second-time normal-pressure steam curing after demolding is conducted. According to the invention, the microsphere powder and the water reducing agent are doped, and a secondary normal-pressure steam curing process is improved in combination with concrete optimization design, so that high-pressure curing after demolding in a conventional process can be avoided, energy consumption can be reduced, equipment cost can be reduced, and safety accidents during production can also be reduced.
本发明本发明公开了一种二次常压蒸养管桩混凝土及管桩生产工艺，所述混凝土包括以下质量份的组份：碎石1320～1450份、砂650～780份、水泥360～480份、微珠粉60～100份、水30～100份、减水剂10～16份。管桩在离心脱水成型后吊到蒸养池进行第一次常压蒸养，第一次常压蒸养后进行脱模，脱模后再吊到蒸养池进行第二次常压蒸养。本发明通过掺入微珠粉和减水剂，同时结合混凝土优化设计改善二次常压蒸养工艺，能够免除常规工艺脱模后的高压养护，降低能源的消耗，降低设备成本，而且，还能减少生产时的安全事故的发生。
