螺杆桩是建筑桩基础中的一种新型节能减排桩,是非排土桩。它具有承载力高、成本低、无泥浆护壁以及无振动的特点,是国家一级工法桩。它的施工对设备的同步控制技术要求很高。提升和加压卷扬机是同步控制技术的关键部件,由原来的双卷筒卷扬机改为大径单排绳、正反双出绳的单卷筒卷扬机,简化了同步控程序,提高了同步控制精度和施工效率。
Screw pile is a new type of energy-saving pile in the construction of pile foundation, is a non-earth-drain pile. It has a high carrying capacity, low cost, non-slippery wall and no vibration characteristics, is a national level method pile. Its construction equipment synchronization control technology is very demanding. The hoisting and pressurizing hoist is a key component of synchronous control technology. It changed from double-drum hoist to large-diameter single-row ropes and double-winded single-drum winches, which simplifies the synchronous control procedure and improves the synchronous control accuracy And construction efficiency.
