Strong Drainage Preloading
1、 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.
