Driftwood Catching Tool "RB Catcher"

- 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."

We have newly added the "RB Catcher," a log capture device installed on impermeable sediment control dams in flow sections, to our product lineup and have started sales. The RB Catcher is directly attached to the upstream part of the impermeable sediment control dam to enhance log capture functionality. Unlike the conventional straight arrangement, it features a structural layout that creates gaps between units, ensuring that water flow is maintained without causing blockages after capturing logs. This allows for the reliable capture of subsequent logs without overflow, preventing damage downstream. By adding this new log capture device to our lineup, we will flexibly respond to various needs in the field.
