Ultrasonic vibration drainage plate for vacuum preloading reinforcement of ultra-soft soil foundation

The utility model relates to an ultrasonic vibration drainage plate for vacuum preloading reinforcement of an ultra-soft soil foundation, which is used for a vacuum preloading test system with a drainage plate and is characterized in that the drainage plate comprises an ultrasonic transducer fixed on the drainage plate. The vacuum preloading drainage consolidation device can effectively prevent the drainage plate from being blocked, improve the vacuum preloading drainage consolidation rate, accelerate pore water pressure dissipation and improve the soil body consolidation effect. 本实用新型涉及一种用于真空预压加固超软土地基的超声波振动排水板，用于带有排水板的真空预压试验系统，其特征在于，所述的排水板包括固定在其上的超声波换能器。本实用新型能够有效防止排水板淤堵，提高真空预压排水固结速率，加快孔隙水压力消散，改善土体加固效果。
