Rigidity-adjustable uplift pile
The invention relates to a rigidity-adjustable uplift pile which comprises an uplift pile body, a rigidity-adjustable connecting piece is arranged on a pile head of the uplift pile body, and the rigidity-adjustable connecting piece comprises a transfer connecting piece, a connecting piece, a connecting piece and a connecting piece, and the transfer connecting piece is fixedly connected to the pile head of the uplift pile body and provided with an inner cavity; the bottom end of the anchoring part is inserted into the inner cavity of the transfer connecting part, and the anchoring part can freely move up and down in the inner cavity and cannot be separated from the inner cavity; the compressible space is arranged between the top of the transfer connecting piece and the anti-floating bottom plate; and the sliding material is arranged on the contact surface of the peripheral side wall of the uplift pile head and the anti-floating bottom plate and the peripheral side wall of the transfer connecting piece and the anti-floating bottom plate. The rigidity-adjustable uplift pile provided by the invention can only provide tensile bearing capacity, and the compression bearing capacity is zero or can be controlled as required. When the underground water level is high, the uplift piles bear pulling force, and the normal uplift resisting effect is achieved; when the underground water level is low, jacking resistance cannot be generated on the anti-floating bottom plate, upper and lower face bidirectional bending moments do not need to be considered for bottom plate reinforcement, and therefore the plane arrangement of the piles is flexible, and the anti-floating efficiency is high.
本发明涉及一种可调刚度抗拔桩，包括抗拔桩，抗拔桩的桩头设置有可调刚度连接件，该可调刚度连接件包括：中转连接件，连接固定在抗拔桩桩头，其具有内腔；锚固件，锚固件的底端插入中转连接件的内腔中，并能够在内腔中上下自由移动且不会脱离；可压缩空间，设置在中转连接件的顶部与抗浮底板之间；滑动材料，设置在抗拔桩桩头周圈侧壁和中转连接件周圈侧壁与抗浮底板接触面处。本发明提出的可调刚度抗拔桩可只提供抗拉承载力，抗压承载力为0或根据需要可控。当地下水位较高时，抗拔桩承受拉力，起到正常的抗拔作用；当地下水位较低时，不会对抗浮底板产生顶托抗力，底板配筋不必考虑上下面双向弯矩，从而桩的平面布置灵活，抗浮效率高。
