Roller pile for eliminating negative friction resistance and construction method thereof
The invention is used for the technical field of pile foundation engineering, and particularly discloses a roller pile for eliminating negative friction resistance and a construction method thereof.The roller pile comprises a lower pile body, the main body of the lower pile body is cylindrical, the lower end of the lower pile body is of a conical structure, and the upper surface of the lower pile body is fixedly connected with a connecting pile body; an upper pile body is fixedly connected to the upper surface of the connecting pile body, and the lower pile body, the upper pile body and the connecting pile body form a complete pile body structure. According to the roller pile capable of eliminating the negative friction resistance and the construction method thereof, the eight sliding grooves are annularly formed in the outer surface of the upper pile body, the rollers are arranged in the sliding grooves and arranged on the outer surface of the steel bar iron ring in a sleeving mode through the bearings, and through cooperation of the rollers and the sliding grooves, when soil around the pile is settled and the outer surface of the steel sleeve is subjected to downward pulling force, namely the negative friction resistance, the negative friction resistance is eliminated; the steel sleeve can slide downwards, negative friction is effectively eliminated, reduction of the bearing capacity of the pile foundation is avoided, and the bearing capacity of the pile foundation is improved.
本发明用于桩基工程技术领域，具体公开了一种消除负摩阻力的滚轮桩及其施工方法，包括下桩体，所述下桩体的主体为圆柱形，且下桩体的下端为圆锥形结构，且下桩体的上表面固定连接有连接桩体，所述连接桩体的上表面固定连接有上桩体，所述下桩体、上桩体以及连接桩体构成了完整的桩体结构。该消除负摩阻力的滚轮桩及其施工方法，本发明中在上桩体的外表面环形设置8个滑槽，滑槽内设置滚轮，滚轮通过轴承套设在钢筋铁圈外表面，通过滚轮与滑槽的配合，桩周土体沉降，钢套筒外表面受到下拉力即负摩阻力时，钢套筒可以向下滑动，有效消除负摩阻力，避免桩基承载力的下降，提高桩基的承载能力。
