High-pressure plunger pump vibration liquefied hardened sand layer auxiliary steel pipe pile anti-drag driving device
The invention discloses a high-pressure plunger pump vibration liquefied hardened sand layer auxiliary steel pipe pile anti-drag driving device which comprises a steel pipe pile, a water jetting mechanism is arranged in the steel pipe pile and comprises a water storage cavity, a high-pressure plunger pump is arranged in the water storage cavity, the bottom of the high-pressure plunger pump is fixedly connected with a water jetting pipe, and the water jetting pipe is fixedly connected with the bottom of the high-pressure plunger pump. The bottom of the water jet pipe is fixedly connected with a water jet nozzle, the top of the water storage cavity is fixedly connected with a water inlet, and the outer portion of the water inlet is in threaded connection with a water inlet cover. Through cooperation of the high-pressure plunger pumps, the water jet pipes and the water jet nozzles, the water pressure is increased through the high-pressure plunger pumps, hardened sand layer jet water vibrates and is liquefied to form a high-pressure water curtain around the steel pipe pile, friction between the steel pipe pile and the hardened sand layer is reduced, the construction difficulty of inserting the steel pipe pile into the ground is reduced, and the construction efficiency is improved.
本发明公开了一种高压柱塞泵振动液化板结砂层辅助钢管桩减阻打设装置，包括钢管桩，所述钢管桩的内部设置有射水机构，所述射水机构包括有储水腔，所述储水腔的内部设置有高压柱塞泵，所述高压柱塞泵的底部固定连接有射水管，所述射水管的底部固定连接有射水喷头，所述储水腔的顶部固定连接有进水口，所述进水口的外部螺纹连接有进水盖。本发明通过通过采用高压柱塞泵、射水管、射水喷头的配合，通过高压柱塞泵增加水的压力，使板结砂层射水振动液化在钢管桩的四周形成高压水幕，减少钢管桩与板结砂层之间摩擦，降低钢管桩插入地面的施工难度，提高了施工效率。
