Ocean pore pressure static sounding continuous injection device and method for silt stratum
According to the ocean pore pressure static sounding continuous penetration device and method for the silt stratum, the small hydraulic jack system and the large hydraulic jack system can be matched; corresponding piston rods are respectively driven to descend the probe rod and the probe of the piezocone penetration test so as to realize continuous penetration of the probe into the silt stratum; after the inner side piston rod reaches the bottom, the outer side piston rod of the outer side hydraulic jack descends through switching to drive the probe rod and the pore pressure static sounding probe to penetrate, and meanwhile, the inner side piston rod of the inner side hydraulic jack ascends at the same time; after the outer piston rod reaches the bottom, the inner piston rod rises to the top at the same time, then the probe rod is circularly driven to penetrate again, the probe rod can be in a downward penetrating state all the time, the piezocone penetration probe can continuously penetrate into the stratum at the constant speed, and the problems that in traditional piezocone penetration operation, penetration is discontinuous, and the penetration efficiency is high are solved. And the situation of long-time interruption exists.
本发明提供一种用于粉土地层的海洋孔压静力触探连续贯入装置及方法，可以通过较小液压千斤顶系统与较大液压千斤顶系统两者之间进行配合，分别带动其对应的活塞杆以下降探杆和孔压静力触探的探头以实现探头连续贯入至粉土地层；当内侧活塞杆到达底部后，通过切换使得外侧液压千斤顶的外侧活塞杆下降带动探杆和孔压静力触探探头贯入，同时令内侧液压千斤顶的内侧活塞杆同时上升；在外侧活塞杆到达底部后，内侧活塞杆同时上升至顶部，进而再次循环带动探杆贯入，可以实现探杆始终处于往下贯入状态，实现了孔压静力触探探头以恒定速率连续贯入地层，突破了传统孔压静力触探作业时，贯入不连续，存在较长时间间断的情况。
