Activities related to the dissemination of road slope disaster prevention technologies and methods in the Kingdom of Bhutan.
Our company implemented the "Dissemination, Demonstration, and Business Development Project for Road Slope Disaster Countermeasures Technology and Methods in Bhutan" under the Japan International Cooperation Agency (JICA) from August 2019 to June 2023. The Kingdom of Bhutan has about 70% of its land in mountainous areas, exposing it to risks of falling rocks and landslides, with slope disasters frequently occurring on its main infrastructure, the roads. This not only causes human casualties and creates isolated areas, but also significantly impacts local industries due to road disruptions. Furthermore, the lack of specialized engineers for rockfall and landslide countermeasures in the country, as well as the absence of companies capable of designing and constructing countermeasure facilities, poses a major challenge. In response, our company has worked on local demonstrations of products to stabilize road traffic and support steady economic development. Specifically, we installed two products, "Geo-Lock Wall" and "Macro Net," on-site. These efforts contribute to reducing human casualties from slope disasters, improving logistics efficiency, and fostering regional economic growth through industrial development. Moving forward, we will continue our activities to promote slope disaster countermeasure technologies and methods on roads in Bhutan and surrounding South Asian countries, contributing to economic development.

Optimal driftwood capture work for measures in the cleaning flow section.
- Erosion control works
A new product has been released to strengthen measures against driftwood in sediment control facilities.
- Measures to enhance the log capture function installed on an impermeable type sediment control dam - Protech Engineering Co., Ltd. (Headquarters: Seiro Town, Kitakambara District, Niigata Prefecture; President: Shoichi Inoue) has developed a new log capture device called "RB (R.B.) Catcher" aimed at reducing log damage caused by the increasing heavy rain disasters in recent years, and has begun sales. The RB Catcher is directly installed in the upstream section of an impermeable type sediment control dam to improve log capture functionality. It can be flexibly adapted without large-scale construction, regardless of whether it is newly installed or existing. In wide river sections, when using the conventional straight arrangement, capturing logs can cause the openings to become clogged. This results in water flow concentrating in the side sections, reducing the water passage capacity, which can lead to damming and the risk of logs overflowing downstream. In the case of this product, the arrangement structure creates gaps between units, allowing for a water passage that prevents blockage by logs. It effectively suppresses damming and ensures that subsequent logs are captured without overflowing. Through the provision of this product, we will contribute to strengthening disaster prevention and mitigation measures. Furthermore, we will continue to focus on product development based on the concept of "basin flood control."
