Construction device and method for super-long immersed tube compaction pile
The invention discloses a construction device and method for a super-long immersed tube compaction pile, and relates to the technical field of construction methods for construction engineering foundation treatment. The main structure of the construction device comprises an outer tube, an inner tube, a power hammer, a main machine tower, a track and a pile driver main machine; and a pile tube adopts an inner tube and outer tube combination method to increase the hole forming depth, a movable steel ring is connected to a conical reducing position at the bottom end of an outer tube through a hinged shaft or a steel wire rope, the outer diameter of the ring is larger than that of the outer tube and accords with the designed hole forming diameter, the inner diameter of the ring is smaller than that of the outer tube, the resistance is greatly reduced during pipe sinking compaction hole forming and pile tube pulling, and the construction efficiency is greatly improved.
本发明公开一种超长沉管挤密桩的施工装置及方法，涉及建筑工程地基处理施工方法技术领域，主要结构包括外管、内管、动力锤、主机塔架及轨道和打桩机主机；桩管采用内外管组合方法增加成孔深度，而且在外管底端锥形变径处铰轴连接或钢丝绳连接一个活动的钢制圆环，其圆环外径大于外管外径并与设计成孔直径相符，圆环内径小于外管外直径，在沉管挤密成孔和起拔桩管时阻力大大减小，施工效率大大提高。
