トーカイスパイラル List of Products and Services

We have published over 1,000 projects that have adopted the TS stainless steel drainage system, showcasing not only the drainage systems but also various types of bridges. We hope you can use this for information gathering and idea searching, and sometimes even as a way to take a break.

• Bridge Construction

In the "Proposal and Case Study for Stainless Steel Drainage Systems for Bridges," we provide information on repair work for "stainless steel drainage manholes" and "high airtight stainless steel drainage pipes," along with their features and case examples. Our products offer a high degree of flexibility in terms of shape, size, and more, allowing for various proposals. We handle everything from proposals, drawings, and estimates to manufacturing, as well as inspections and construction of drainage pipes.

• Bridge Construction

This is a stainless steel drainage device that integrates a thin drainage pipe with a fully curved thin stainless steel plate, which has received positive feedback. NETIS Listed Product: CB-190003-A Main Features: - By covering existing pipes with a plate-integrated drainage pipe, it effectively prevents water leakage along the overhang and the underside of the floor slab, while also enhancing aesthetics. - Improved workability due to its lightweight design and cost reduction from material savings. The installation on the plate section reduces the need for support brackets. - Enhanced durability through the use of stainless steel materials. We also provide assistance with various comparison tables, proposals, drawings, and estimates. We look forward to your inquiries, whether related to design or on-site matters.

• Foundation construction

- Tokai Spiral's TS stainless steel drainage pits can be manufactured and proposed in various shapes. There are no mold costs, so please feel free to consult us for comparison tables, designs, drawings, estimates, etc., starting from just one unit. - Our products are made of thin stainless steel, achieving lightweight, long lifespan, and low cost. (For construction requiring wheel load support, we can accommodate with grating specifications.) - Especially in repair work, we can make proposals tailored to the site, and we have received positive feedback including design services.

• Bridge Construction

Ideally, drainage should be vertical. However, due to the structure of the bridge and other reasons, there may be cases where drainage is done using horizontal pipes buried in the ground. In such cases, it is often difficult to maintain the proper slope, which can lead to blockages. At Tokai Spiral, we offer products with shapes that facilitate easy cleaning to address the above issues.

• Bridge Construction

The cylindrical formwork of the Tokai Spiral is manufactured by winding strip steel in a spiral shape and "folding" both ends of the coil, and by adding three ribs between the folds, it ensures three times the strength without increasing the weight of the pipe, thereby enhancing reliability.
