Automatic drainage liquefaction resistance rigid pile with flow velocity controllability
The invention discloses an automatic drainage liquefaction resistance rigid pile with flow velocity controllability. The automatic drainage liquefaction resistance rigid pile with the flow velocity controllability comprises a precast pile. A groove is formed in the side face of the precast pile, a steel plate is fixedly arranged on the opening side of the groove, and multiple water permeating holes are formed in the surface of the steel plate. A communication device is arranged in the groove and comprises a piece of insulating plastic. The insulating plastic is fixed to the side wall of the interior of the groove, a dynamic pore water pressure sensor is arranged in the insulating plastic, and a metal conductor is arranged on the protruding portion of the insulating plastic. The metal conductor and the dynamic pore water pressure sensor are connected with a control circuit, the control circuit is connected with a water suction pump, and the water suction pump is connected with a water pumping pipe in the groove. By the adoption of the automatic drainage liquefaction resistance rigid pile with the flow velocity controllability, the pore water which flows into a drainage body from a soil body can be quickly pumped out, and the dissipation speed of the excess pore water pressure in the soil body is increased. In addition, the pump is driven by a storage battery, is automatically started and stopped to pump the water, the manual start and stop and the maintenance are avoided, the workload is reduced, the power of the pump changes along with the change of the pore water pressure,and the utilization of energy is more reasonable.
本发明公开了一种可控流速的自动排水抗液化刚性桩，包括预制桩，预制桩的侧面设有凹槽，凹槽的开口侧固定有钢板，钢板表面设有若干透水孔，凹槽内设有联通装置，所述的联通装置包括绝缘塑料，所述的绝缘塑料固定在凹槽内部侧壁上，绝缘塑料内置有动态孔隙水压力传感器，绝缘塑料的突起处设有金属导体，所述金属导体及动态孔隙水压力传感器分别与控制电路连接，所述控制电路与抽水泵连接，所述的抽水泵与凹槽内的抽水管连接。本发明能够使土体涌入排水体中的孔隙水快速被抽出，加快土体中超孔隙水压力消散速率，且泵机以蓄电池驱动，自动启动、关闭抽水，免去人工开关与维护，减轻了工作负担，泵机功率随孔隙水压力变化而变化，利用能源更加合理。
