We would like to introduce a case study of our product, the temporary protective fence "QT Fence." ■ Temporary Protective Fence "QT Fence" This is a waiting-type temporary protective fence. Its simple structure and lightweight materials allow for quick installation and removal by hand. Based on the technical expertise cultivated through our past achievements, we will contribute to disaster prevention measures and the development of the industry through the development of construction methods and technologies.

- 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."
