Reinforcement device for expanded-base cast-in-place pile
The invention discloses a reinforcement device for an expanded-base cast-in-place pile. The reinforcement device comprises a movable inner stirrup, an elastic telescopic piece, a plurality of expanded-base section reinforcements and a limiting inner stirrup; one end of each expanded-base section reinforcement is movably connected with the movable inner stirrup, and the other end of each expanded-base section reinforcement is movably connected with the limiting inner stirrup; the two ends of the elastic telescopic piece are fixedly connected with the movable inner stirrup and the limiting innerstirrup respectively; each expanded-base section reinforcement at least comprises two sections, and when the elastic telescopic piece is in a free state, a certain included angle is formed between the two sections of each expanded-base section reinforcement; and when the elastic telescopic piece is in a tightened state, the two sections of each expanded-base section reinforcement are in a straight line. The reinforcement device provided can greatly improve the shear resistance and tensile strength of the manual digging type expanded-base cast-in-place pile of a power transmission line, so that the bearing capacity of the manual digging type expanded-base cast-in-place pile of the power transmission line is exerted to the maximum extent, and the compression resistance and pulling resistance bearing capacity of the manual digging type expanded-base cast-in-place pile of the power transmission line are further improved.
一种用于扩底灌注桩的配筋装置，配筋装置包括：活动内箍筋、弹性伸缩件、多个扩底段配筋和限位内箍筋；每根扩底段配筋的一端分别与活动内箍筋活动连接，每根扩底段配筋的另一端分别与限位内箍筋活动连接；弹性伸缩件的两端分别与所述活动内箍筋和所述限位内箍筋固定连接；每根扩底段配筋至少包括两段，当弹性伸缩件处于自由状态时，扩底段配筋的两段具有一定夹角；当所述弹性伸缩件处于绷紧状态时，扩底段配筋的两段为一条直线；本发明提供的配筋装置，能够极大地提高输电线路人工掏挖型扩底灌注桩的抗剪、抗拉强度，从而最大程度发挥输电线路人工掏挖型扩底灌注桩的承载能力，进而提高输电线路人工掏挖型扩底灌注桩的抗压和抗拔承载能力。
