The "Lattice Gutter" is a tunnel reinforcement rebar support used as a hollow retaining material for reinforcing rebar in standard lining sections and water-tight lining sections of road tunnels. Compared to H-shaped rebar supports, it is lighter in weight and has better concrete fillability. Since it is directly attached to the main body of the lattice gutter, the installation accuracy of the reinforcing rebar is improved. 【Features】 ■ Allows installation of reinforcing rebar without penetrating the waterproof sheet with hanging fixtures, etc. ■ Lighter in weight compared to H-shaped rebar supports ■ Better concrete fillability compared to H-shaped rebar supports ■ Improved installation accuracy of reinforcing rebar due to direct attachment to the main body of the lattice gutter *For more details, please refer to the PDF document or feel free to contact us.

Introducing the "Reinforced Steel Hanging Fittings for Tunnels." In tunnel lining, reinforced steel hanging fittings suitable for the thickness of the tunnel lining are installed, allowing for the securement of staging bars. This enables the assembly of rebar in the correct positions. 【Construction Flow】 1. Install the base 2. Install the waterproof sheet 3. Apply butyl tape 4. Install the round seat 5. Install the high nut 6. Install the single-thread bolt 7. Install the staging bars *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "Soundproof Doors for Tunnels." "Soundproof Doors" were developed as a measure to suppress vibrations and noise during tunnel blasting operations. Depending on the customer's site conditions and applications, you can select from the following soundproof doors and place an order. 【Types of Soundproof Doors】 ■ Underground Type Soundproof Door (Fixed) ■ Portal Type Soundproof Door (Fixed) ■ Portal Mounted Type Soundproof Door (Fixed) ■ Sled Type Soundproof Door (Mobile) *For more details, please refer to the PDF document or feel free to contact us.

This machine is a device that mechanically and uniformly applies curing agents during the initial curing of concrete pavement. It is expected to improve economic efficiency by reducing labor costs and material loss, as well as enhancing quality, safety, and workability. Traditionally, workers performed the task manually using a sprayer. Compared to manual application, the automatic curing agent dispensing machine is expected to maintain a consistent amount of curing agent without increasing the workforce. As a result, it helps maintain the appropriate moisture level and ensures sufficient curing, contributing to the durability of the concrete! ■ Automatic Curing Agent Dispensing Machine <NETIS Registration Number: CB-240009> The machine can be easily operated by one operator using an electric control panel for both main operation and dispensing. After work is completed, it only requires rinsing the pump with water, making daily maintenance less burdensome. It was registered with NETIS in 2024! ■ Manual Curing Agent Dispensing Machine Dispensing is done by workers pushing the dispensing machine on the workbench, moving it left and right while applying the curing agent.

■About the laser machine introduced by our company ★Recently, a remarkable technological innovation: "fiber" laser machines! ★Specialized in processing medium plates (thickness less than 3-6mm) and thick plates (6mm or more)! ★Achieves high-speed piercing (drilling) processing and high-quality, precise cutting! ★The maximum processing size is 1.5×3.0m, focusing on the most requested mid-range steel processing! ★Enhanced automation peripheral devices and utilization of IoT to achieve high productivity!

★Newly registered in NETIS in November 2024★ *Vibration barriers serve to reduce construction vibrations simply by being installed on the ground surface; they are a technology for addressing vibration propagation pathways. *Unlike traditional measures for addressing propagation pathways, they do not require large-scale temporary facilities or construction, making them a highly effective technology in terms of workability and safety. *There are two types of vibration barriers: "mass bodies" and "vibration systems," and by arranging them according to their purpose, they demonstrate a high reduction effect.

The rough surface finish greatly influences the quality of concrete pavement. The product we have developed this time is the specialized broom for rough surface finishing (broom finish) called 'SOMENDER'. Previously, we received feedback about the brooms we handled, such as "the bristles come out easily," "the broom body and handle tend to bend easily," and "they deteriorate significantly with continued use on-site." To address these issues, we have completed 'SOMENDER,' which has the following features: ★ The main body is made of recycled plastic material, and the upper attachment part is made of aluminum pipe material, significantly improving durability! ★ Lightweight and enhanced water resistance! ★ Bristles are less likely to come out! Please feel free to contact us if you have any requests.

<Newly Developed Products for Concrete Pavement> 【Rough Surface Finishing Broom 'SOMENDER'】 This is a broom specifically designed for rough surface finishing (broom texture finishing) that addresses concerns such as "bristles easily fall out" and "the broom body and handle easily bend." In September 2024, the specifications were renewed to make it more user-friendly and durable! 【Protective Cap with Screw-Type Tie Bar Protrusion 'NONSEARCHER'】 This protective cap is designed to be attached to the female connection hole of screw-type tie bars at vertical joints on continuous reinforced concrete pavement (slipform method) sites. The protruding plate from the concrete makes it easier to confirm the position of the tie bar, contributing to improved efficiency and labor-saving in the work process! ★Registered with NETIS in September 2024【CB-240025-A】 【Automatic Curing Agent Spraying Machine for Concrete Pavement】 The spraying of curing agents, which was previously done manually by workers, has been automated. This machine sprays the curing agent in a uniform and appropriate amount, not only improving the quality of the pavement but also reducing the number of personnel required for the curing process, achieving labor savings! ★Registered with NETIS in May 2024【CB-240009-A】 *For more details, please download the catalog or contact us directly.
