Construction examples of small cross-section tunnels.

It is possible to carry out the necessary amount of work at the site in a short time when needed! We are currently providing case materials for repairs of existing water supply tunnels and existing railway tunnels.

The "Disaster Recovery Tunnel Repair Spraying Construction System" achieves low dust and low rebound through the synergistic effect of liquid quick-setting agents and Denka PF mortar. Denka PF mortar has high compressive and flexural strength, and its toughness is also improved. It has good adhesion and can be sprayed even in areas with water inflow. With the push of a button, automatic spraying is possible, making operation and cleaning simple, and it can be constructed using only the compact M-PAC (spraying system). 【Features】 ■ Low dust and low rebound ■ High strength ■ Easy operation ■ Compact ■ Pre-mixed *For more details, please refer to the PDF materials or feel free to contact us.

The "CCS2" is a ceiling-mounted vehicle counting sensor that employs an infrared reflection method. It can detect vehicles in both directions with a single unit, accurately counting vehicles even during traffic jams or when vehicles pass each other. Additionally, this product can be used not only for vehicle counting but also as a sensor for departure warnings. Furthermore, by using a separately sold dedicated remote control, it is easy to reset the sensor alone, switch the counting direction, and change the patterns of the departure warning timer. 【Features】 ■ Angle adjustment up to ±5° ■ Can be installed in locations with high ceilings up to 4m ■ Detection area consists of 40 spots, allowing for extensive detection ■ The display LEDs are color-coded by direction, making operation confirmation easy.

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. We have many implementation examples available, so please take a look at the case study page.

We have added site photos of the Danjiang Bridge, currently under construction in Tamsui District, New Taipei City, Taiwan (taken on August 19, 2025), to our company website (Projects). The main tower will reach a height of 200 meters above the water surface. According to the plan, the main tower will be constructed in 53 floors, with each floor featuring a complex variation in shape. As of the end of August 2025, the construction of up to the 52nd floor has been completed. The construction of the main tower has now entered its final stage. Please check our company website (Projects) for more information. ■ Project Name: "Danjiang Bridge Project" If completed, the Danjiang Bridge, designed by the late Zaha Hadid, will be the longest single-tower, asymmetrical cable-stayed bridge in the world. The construction of this reinforced concrete main tower utilizes the Perry System (SCS+VARIO and ACS+VARIO). Additionally, this project has been awarded as an all-Perry project, receiving support from the Perry Group's project and technical teams through Perry Japan as the point of contact.
