Prefabricated foundation pile and construction method thereof
The invention discloses a prefabricated foundation pile and a construction method thereof. The prefabricated foundation pile comprises a prefabricated inner pile and a prefabricated outer pile, wherein at least one of the two ends of the prefabricated inner pile is of a tapered cone structure with a small end facing outwards, at least one of the two ends of the prefabricated outer pile is an openend, an inner passage which communicates with the open end and can accommodate the prefabricated inner pile is arranged in the prefabricated outer pile, at least two sets of soil mass implanters arranged at intervals in the length direction of the prefabricated outer pile are arranged on the prefabricated outer pile, each set of soil mass implanter comprises at least two outwardly movable insertion pins arranged circumferentially around the inner passage, and the inner ends of the insertion pins can make contact in the inner passage to form through holes adapted to the end of the cone structure. The prefabricated foundation pile can adopt a smaller pile foundation length to achieve high compression resistance and pullout resistance, can meet more usage scenes and has the advantage of goodapplicability.
本发明公开了一种预制根基桩及其施工方法，其中，预制根基桩包括预制内桩和预制外桩，预制内桩的两端至少有一端为呈锥形且小端朝外的锥体结构，预制外桩的两端至少有一端为开口端，预制外桩的内部具有与开口端相通且可容纳预制内桩的内通道，预制外桩上设置有至少两组沿预制外桩的长度方向间隔布置的土体植入器，每组土体植入器包括至少两个可向外活动的且环绕内通道周向布置的插销，其中，各个插销的内端可在内通道内相接触而形成与锥体结构的端部相适配的通孔。该预制根基桩可采用较短的桩基长度达到较强的抗压性能和抗拔性能，可满足更多的使用场景，具有适用性好的优点。
