Fully-fabricated threaded steel pipe UHPC (Ultra High Performance Concrete) combined pile foundation and construction method thereof
The invention discloses a full-fabricated threaded steel pipe UHPC combined pile foundation and a construction method thereof, and relates to the technical field of pile foundations, the full-fabricated threaded steel pipe UHPC combined pile foundation comprises a supporting bearing platform and a plurality of pile foundation single bodies, the supporting bearing platform is provided with a plurality of mounting grooves, and the upper ends of the pile foundation single bodies extend into the mounting grooves; each pile foundation single body comprises a deformed steel bar pipe pilot pile and a plurality of deformed steel bar pipe extension piles, the plurality of deformed steel bar pipe extension piles are sequentially connected from top to bottom, and the upper end of the deformed steel bar pipe pilot pile can be connected with the lower end of the deformed steel bar pipe extension pile located at the lowermost end; pilot prefabricated filling piles are arranged in the threaded steel pipe pilot piles, extension prefabricated filling piles are arranged in the threaded steel pipe extension piles, and the pilot prefabricated filling piles and the extension prefabricated filling piles are made of UHPC. The problems that a traditional grouting deformed steel bar pipe pile is complex in construction procedure, long in construction period and insufficient in bearing capacity, and environmental pollution is caused during on-site grouting can be effectively solved.
本发明公开了一种全装配式螺纹钢管UHPC组合桩基及其施工方法，涉及桩基技术领域，其中装置包括支撑承台和多个桩基单体，支撑承台上设有多个安装凹槽，桩基单体的上端伸入到安装凹槽内；桩基单体包括一个螺纹钢管先导桩和若干个螺纹钢管延长桩，若干个螺纹钢管延长桩从上至下依次连接，螺纹钢管先导桩的上端能够与位于最下端的螺纹钢管延长桩的下端相连接；螺纹钢管先导桩的内部设有先导预制填充桩，每个螺纹钢管延长桩的内部设有延长预制填充桩，先导预制填充桩和延长预制填充桩的材质均为UHPC。本发明可以有效解决传统注浆螺纹钢管桩施工工序复杂、施工周期长、承载能力不足以及现场注浆时带来的环境污染等问题。
