Sand pile砂桩
█Casing pipe is correctly positioned.
█Casing pipe is driven into the ground using a vibro-hammer.
█When it reaches the required depth, the casing pipe is charged with a specified volume of sand.
█As the casing pipe is raised by a specified margin, the sand is discharged into the ground pressed air.
█The sand pile pacted and enlarged by driving the pipe back down into the sand
█The pipe-raising, sand discharge and re-driving procedure is repeated numerous times as the pipe is gradually removed, forming pacted sand pile
█套管处于正确的位置。
█用vibro-hammer驱动套管。
█充满砂子的套管到达所需要的深度。
█用压缩空气通过套管边缘将砂子吹入入地下。
█进入套管的砂子被不断的夯实和扩大。
█套管不断的提升,连续不断的砂子排放和震动过程形成一个完整的致密砂桩。
ration打入 wave pattem波形 filling material填料
1、Casing pipe is positioned and predetermined quantity of filling material is charged into the casing.
2、Casing is rotated and driven smoothly into the ground.
3、Casing is fully rated to the designated depth.
4、While casing is lifted by predetermined height, filling material is discharged from the casing.
5、Casing is re-driven pact discharged filling material and surrounding ground.
6、Steps 4 and 5 are repeated by using a wave pattern and casing is gradually lifted, consequently formation of an enlarged pile is achieved.
1、套管定位和预定的数量的充填材料冲进了套管。
2、套管回转和驱动平稳进入地层
3、套管到达设计深度
4、提升套管同时套管内的填充料下放
5、驱动套管并压缩填充材料和周围地层
6、用同样的方式重复4、5步,逐步提升套管,形成扩大的砂桩
