The four-sided earth retention is completed quickly! The lightweight design makes installation and removal easy. Suitable for small to large-scale construction projects.
The "Tsupariman" is a four-sided integrated support material that can be easily installed at excavation sites. It is lightweight, utilizing aluminum materials for its main components, making installation and removal easy. Compared to methods that combine belly braces and cutting beams, it can shorten construction time. Connection is as simple as securing the jacks at the four corners with pins. Depending on the site environment, it can be assembled and installed or removed within the excavation, making it usable even in narrow construction environments such as bridge piers. Additionally, it features a gear mechanism that is resistant to failure, preventing freezing and water leakage. Using dedicated working rods, dimensions can be adjusted to match the excavation width. 【Features】 ■ NETIS registration number: QS-190027-A ■ No need for intermediate beams, ensuring a wide working space ■ Pins can be removed within the excavation site, allowing for disassembly and removal ■ Available for large-scale excavation work (Model 1515B) and small to medium-scale excavation work (Model 1210D) ■ Compliant with the soil retention pre-construction method recommended by the Ministry of Health, Labour and Welfare *For more details, please refer to the materials.
