Prefabricated foundation pile body capable of reducing negative friction
The prefabricated foundation pile body capable of reducing the negative friction resistance solves the problem that the negative friction resistance borne by an existing pile body is reduced in a limited mode and comprises a soil layer, a containing hole is formed in the soil layer, the pile body is installed in the soil layer in a matched mode, a protection cylinder is installed on the side wall of the pile body in a matched mode, and a telescopic rod is rotatably installed on the side wall of the protection cylinder; first springs are fixedly mounted on the bottom wall and the top wall in the telescopic rod, fixing plates slidably mounted on the side wall of the protective barrel are rotatably mounted on the side, away from the protective barrel, of the telescopic rod, a right-angle plate is slidably mounted between every two adjacent fixing plates, and a telescopic groove plate is fixedly mounted at the bottom of the placement hole. When the protection barrel is installed, the fixing plate extrudes a surrounding soil layer to enable the soil layer to be extruded, sealing of soil around the pile is improved, settlement of the soil around the pile can be prevented, the protection barrel is matched with the bearing platform through extrusion of the telescopic rod to reduce load of the pile body, and when the soil around the pile settles, the sliding plate is matched with air in the telescopic plate to enable settlement force to become upward force provided for the pile body and the bearing platform. And the negative friction is effectively reduced.
本发明涉及一种可降低负摩阻力的预制地基桩体，该装置解决了现有桩体受到负摩阻力降低有限的问题，包括土层，土层内部开设放置孔且土层内部配合安装有桩体，桩体侧壁配合安装有防护筒且防护筒侧壁转动安装有伸缩杆，伸缩杆内部底壁与顶壁固定安装有第一弹簧且伸缩杆远离防护筒一侧转动安装有滑动安装于防护筒侧壁的固定板，两相邻固定板之间滑动安装有直角板，放置孔底部固定安装有伸缩槽板；防护筒安装时，固定板挤压周围土层使其受挤压，提高桩周土的密封，可预防桩周土沉降，通过伸缩杆挤压使防护筒配合承台使桩体减少负荷，桩周土沉降时，滑动板配合伸缩板内部空气，使沉降力变成对桩体以及承台提供向上的力，有效的降低负摩阻力。
