Strong Drainage Preloading
1、 Sunzo invent patent;
2、Greater than 80Kpa negative pressure can be add to soft soil depth, vacuum transmit almost lossless;
3、Reducing effect of water resistance and well resistance which bad for drainage consolidation, eliminating the dead zone of traditional vacuum preloading drain channel;
4、Solving the problem of siltation in vertical drain channel, flow rate fastly ,MUD consolidate quickly, water content under 55%;
5、Adequate quality, shorten construction period, high performance cost ratio.
