Steel pipe pile sinking device
The invention provides a steel pipe pile sinking device. The steel pipe pile sinking device comprises a pile cap arranged at the top end of a steel pipe pile; the bottom end of the supporting cylinder is arranged on the pile cap; the pile hammer is arranged on the outer side of the supporting cylinder in a sleeving manner; the lifting mechanism is connected with the pile hammer and used for driving the pile hammer to move along the supporting cylinder; and the slewing mechanism is arranged on the pile hammer and the pile cap and used for enabling the pile hammer to impact the pile cap vertically and downwards or enabling the pile hammer to rotate relative to the pile cap and impact the pile cap. According to the method, the problem that the pile cannot be sunk to the designed depth due to the fact that a hammer is rejected in the pile sinking process due to soil plugs, hard strata and the like can be solved, the damage to soil layers around the pile and at the pile end is small, the bearing capacity loss of the pile is small, the equipment hoisting frequency is reduced, the application field of the steel pipe pile is greatly expanded, energy consumption is reduced, and the construction efficiency and safety are obviously improved.
本发明提供了一种钢管桩沉桩装置，包括：用于设置在钢管桩顶端的桩帽；支撑圆筒，其底端设置在桩帽上；桩锤，其套设在支撑圆筒的外侧；提升机构，其与桩锤连接，用于驱动桩锤沿支撑圆筒移动；回转机构，其设置在桩锤和桩帽上，用于使得桩锤垂直向下冲击桩帽，或者，用于使得桩锤相对桩帽转动并冲击桩帽。本发明可解决沉桩过程中因土塞、硬质地层等原因导致拒锤无法将桩沉入设计深度的问题，且对桩周及桩端土层破坏少，桩的承载力损失少，并减少设备吊装次数，极大扩展了钢管桩适用场地，降低能耗，明显的提高施工效率、安全性。
