在海中进行静力触探时,由于海水具有很大的腐蚀作用,所以对探头除了要求有较高的灵敏、稳定和防水密封性能外,还必须要求能够对探头内部的浸水部分进行彻底的清洗保养,以防止海水对探头零件活动部位的配合间隙和传感器变形间隙的腐蚀生锈而失灵。目前的双桥探头,其压力杆和摩擦传感器的变形间隙一般都是无法清洗的死角。 During the static penetration test in the sea, due to the great corrosive effect of seawater, in addition to requiring high sensitivity, stability and waterproof sealing performance, the probe must also be able to thoroughly clean the water-immersed part inside the probe. Maintenance, to prevent the sea water from rusting and rusting due to the fitting clearance of the active part of the probe part and the deformation gap of the sensor. At present, the double-bridge probe, the deformation gap of the pressure rod and the friction sensor is generally a blind spot that cannot be cleaned.
