Features

No impact on surroundings

- Ensuring safety without influence on neighboring structures or surrounding ground
- Requiring no soil improvement and having no influence on groundwater
- Little vibration noise

Excellent installability

- Securing high vertical precision
- Securing high water resistance
- Allowing safe construction as no workers need to work inside the shaft when setting the caisson
- Reducing work period by continuous operation with effective use of space
- Easy-to-handle segmented members

Can be used under constraints

With a setting device that can be flexibly raised and lowered, it can be used in narrow construction yards.
Can be used in places with height restrictions (under elevated tracks/indoors).
Supporting construction in a temporarily occupied zone (under road lining), which allows for opening the road

Can be used for a wide range of applications

- Profile: circular/oval
- Outer diameter: 3 m or more
- Depth: up to about 70 m
- Soil: soft silt, clay, sand, gravel, soft rock, medium hard rock
