We would like to introduce our "Bridge Collapse Prevention System for Water Pipe Bridges." The pin-type bridge collapse prevention device "SE Limiter W" can resist seismic forces from level 2 earthquakes in two directions: along the bridge axis and perpendicular to the bridge axis, using a single device. It can be used not only for new water pipe bridges but also for seismic reinforcement of existing water pipe bridges. The small-capacity collapse prevention cable "F10TD" features a cable section coated with anti-rust oil on PC steel wire, and is covered with polyethylene, offering excellent water resistance and durability. Our company provides products that protect water pipe bridges, which are essential urban infrastructure and vital for daily life, from earthquake damage, contributing to the creation of a safe and secure society. 【Product Lineup】 ■ Pin-type bridge collapse prevention device "SE Limiter W" ■ Small-capacity collapse prevention cable "F10TD" *For more details, please refer to the PDF document or feel free to contact us.

The various structures that support modern society are becoming increasingly important year by year, requiring high durability, seismic resistance, and safety. Our company responds to the realization of "various structures" with our innovative ideas and technical skills cultivated through our past achievements. Production is carried out in our own factory, from can manufacturing to machining and surface treatment, ensuring the creation of high-precision, high-quality products. In recent years, due to the aging of equipment, the adoption of stainless steel has increased for its ease of maintenance from a durability perspective. We incorporate the experience gained from the production of stainless steel piping to create high-precision, high-quality products.

We would like to introduce our "Double Pipe Type Water Pipe Bridge." This structure incorporates a water pipe within a sheath pipe. In water pipe bridges (pipe beams with flange reinforcement), it becomes possible to accommodate spans that were traditionally not applicable for small-diameter water pipes. Additionally, in bridge-mounted pipes, it is used as an outer pipe when insulation is required. Since the water pipe is integrated within the sheath pipe, maintenance and management are not possible, making it crucial to ensure quality during the manufacturing of the water pipe. 【Lineup】 ■ Double Pipe Type Water Pipe Bridge ■ Double Pipe Type Mounted Pipe *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our company's "water pipe bridge" in the form of a road bridge attachment. This format involves supporting the water pipe with support materials attached to a road bridge (steel bridge or PC bridge), which can be broadly categorized into external and internal attachments based on the installation position. The structural concept corresponds to a pipe beam format with multi-span continuous support based on the support materials. Measures against the relative displacement of the road bridge and the water pipe's expansion and contraction during an earthquake (examination of the expansion performance of flexible expansion joints), as well as the consideration of accessories such as air valves and construction methods, are important. 【Lineup】 ■ External attachment (steel bridge) ■ Internal attachment (PC bridge) *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our company's four-string truss reinforcement type "water pipe bridge." It has greater horizontal rigidity compared to the triangular truss reinforcement type and is suitable for relatively long spans. It is primarily used as a lower chord member in cases with two water pipes, and it excels compared to the triangular truss reinforcement type when there are multiple attachments or when the span is long, especially as a dedicated attachment bridge. 【Lineup】 ■ Four-string truss reinforcement type ■ Four-string truss reinforcement type (dedicated attachment bridge) *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our company's triangular truss reinforced type "water pipe bridge." When there is one water pipe, an inverted triangular truss reinforcement type is used, and when there are two water pipes, a triangular truss reinforcement type is employed. The triangular truss reinforcement type is often used as a dedicated bridge for supporting water pipes. This water pipe bridge utilizes the water pipe as either the upper chord or the lower chord, effectively leveraging the characteristics of steel pipes as truss components, and is widely adopted for small to medium diameters. 【Lineup】 ■ Inverted triangular truss reinforcement type ■ Triangular truss reinforcement type *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our company's flange stiffening type "water pipe bridge." This stiffening method involves welding π-shaped or T-shaped stiffening beams to the upper or lower part of the water pipe, thereby increasing the cross-sectional rigidity of the water pipe. Depending on the span and diameter, it can be more economical than truss or arch stiffening, even if the steel weight is somewhat heavier. Flange stiffening can be broadly classified into two types: upper stiffening type (welding the stiffening beams above the steel pipe) and lower stiffening type (welding the stiffening beams below the steel pipe). 【Lineup】 ■ Upper stiffening type ■ Lower stiffening type *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our company's pipe beam type "water pipe bridge." It can be broadly classified into four types: simple support type, one end fixed and the other end free support type, both ends fixed type, and continuous support type. This design effectively utilizes the toughness of steel pipes, allowing the water pipe itself to act as a girder to support the applied loads, and it has a proven track record as a water pipe bridge. 【Lineup】 ■ Simple support type ■ One end fixed and the other end free support type *For more details, please refer to the PDF materials or feel free to contact us.
