Pile feeder suitable for prestressed pipe pile construction of stiff composite pile
The invention relates to the technical field of pile feeders, and discloses a pile feeder suitable for prestressed pipe pile construction of stiff composite piles, which comprises a pipe body, a clamp is fixedly connected to the bottom of the pipe body, a columnar large-diameter section is formed at the upper part of the clamp, a columnar small-diameter section is formed at the lower part of the clamp, and a plurality of hydraulic cylinders are arranged in the small-diameter section. A hydraulic rod is arranged at the front end of the hydraulic cylinder, the outer end of the hydraulic rod is exposed on the outer side of the small-diameter section and connected with a clamping piece, and the outer end face of the clamping piece forms an abutting face; the bottom of the large-diameter section is provided with an annular bottom face, a plurality of rail grooves are formed in the bottom face, and sliding blocks are arranged at the tops of the clamping pieces and embedded into the rail grooves. A center hole is formed in the middle of the large-diameter section, a hydraulic oil pipe penetrates through the center hole, the bottom of the hydraulic oil pipe is connected with a hydraulic cylinder, the small-diameter section is embedded into the prestressed pipe pile, the hydraulic cylinder drives the hydraulic rod to move outwards, and the sliding block moves outwards in the extending direction of the rail groove till the abutting faces of the clamping pieces abut against the prestressed pipe pile.
本发明涉及送桩器的技术领域，公开了适用于劲性复合桩的预应力管桩施工的送桩器，包括管体，管体的底部固定连接有夹具，夹具的上部形成柱状的大径段，夹具的下部形成柱状的小径段，小径段中具有多个液压缸，液压缸的前端具有液压杆，液压杆的外端显露在小径段的外侧与夹片相连接，夹片的外端面形成抵接面；大径段的底部具有环形的底部面，底部面上形成有多个轨槽，夹片的顶部设有滑块，滑块嵌入至轨槽中；大径段的中部设有中心孔，中心孔穿入有液压油管，液压油管的底部与液压缸相连接，将小径段嵌入至预应力管桩中，通过液压缸驱动液压杆朝外移动，滑块沿着轨槽的延伸方向朝外移动，直至多个夹片的抵接面抵紧在预应力管桩上。
