Significant reduction in on-site construction period is possible! This is a construction method that achieves improved workability and construction accuracy.
The "Kekomu Segment Method" uses a full-circle rotating press-in machine to underwater press-in excavate a concrete composite pipe covered with outer steel plates, constructing a vertical shaft to a specified depth. Unlike conventional methods, after construction, it remains as a manhole structure with part of it left intact, allowing for the omission of on-site pouring work. Additionally, the connection of the segments is designed to be flexible, accommodating seismic level 2. 【Features】 ■ Work inside the vertical shaft to construct the manhole can be omitted by building an inner frame ■ Process time reduced to one-third ■ Complies with seismic level 2 ■ Improved environmental performance, constructability, and construction accuracy *For more details, please download the PDF or feel free to contact us.
