Bearing type anti-liquefaction drainage pile
The invention provides a bearing type anti-liquefaction drainage pile, and belongs to the technical field of geotechnical engineering. The bearing type anti-liquefaction drainage pile comprises a pilebody, a force bearing disc and a pile root, wherein longitudinal grooves are evenly formed in the periphery of the surface of the pile body; certain distances are reserved between the grooves and thetop and the bottom of the pile body; a water permeable net plate and a stainless steel buckle plate are arranged at the outer portion of each groove; a cavity is formed among the outer side of each groove, the corresponding water permeable net plate and the corresponding stainless steel buckle plate; the water permeable net plates and the stainless steel buckle plates are alternately arranged; water permeable holes are formed in the water permeable net plates; drainage holes communicating with the grooves are formed in the positions, above the corresponding positions of the grooves, of the top of the pile body; the pile body, the force bearing disc and the pile root are integrally poured into the drainage pile; and longitudinal steel bars are arranged in the drainage pile. According to the bearing type anti-liquefaction drainage pile, the load and stress action of an upper building and a foundation is borne, ultra-gap water generated by a liquefiable soil layer due to cyclic loads isdrained in time, and the liquefaction phenomenon is prevented.
一种承载式抗液化排水桩，属于岩土工程技术领域，包括桩体、托力盘、桩根，所述桩体表面一周均匀设有纵向的凹槽，所述凹槽与桩体顶部、底部留有一定距离，每个凹槽的外部设有透水网板、不锈钢扣板，所述凹槽外侧与透水网板、不锈钢扣板之间形成空腔，所述透水网板、不锈钢扣板交替设置，所述透水网板上设有透水孔，所述桩体顶部于凹槽对应位置上方设有与凹槽相连通的排水孔，所述桩体、托力盘、桩根一体浇筑成排水桩，所述排水桩内设有纵向钢筋。本发明实现承载上部建筑和基础的荷载和应力作用，又及时将可液化土层因循环荷载产生的超空隙水排出，防止液化现象发生的桩基结构。
