在翻造建筑物时,原则上要不影响周围环境,在较短时间内完工,且要达到经济、牢固的目的。对各种桩基反复慎重地作了研讨后,我们决定采用振动水冲碎石桩。振动水冲碎石桩是用ZQC-30振冲器,成孔时,由喷嘴射出3～5kgf/cm~2的水柱,破坏了上颗粒间的摩擦力和内聚力,使土质稀释饱合,在振冲器的自重(包括悬吊系统)的作用 When building a building, in principle, it will not affect the surrounding environment, and it will be completed in a relatively short period of time, and it must achieve economical and firm objectives. After repeated and cautious discussions on various pile foundations, we decided to use vibration water to break stone piles. The vibratory water-shocked stone pile is made of ZQC-30 vibrator, when the hole is formed, the nozzle ejects 3~5kgf/cm~2 water column, which breaks the friction and cohesion between the upper particles, so that the soil is diluted and saturated. The vibrator’s own weight (including the suspension system)
