Lightweight and strong detachable water stop board for infrastructure.
Infrastructure equipment protection: Installation completed with a small number of people. High water-stopping power with two locks.
In infrastructure facilities, it is essential to protect critical equipment from flooding caused by typhoons, sudden heavy rain, and linear precipitation zones. Once flooding damage occurs, it can take a significant amount of time and cost to halt operations and carry out recovery work, potentially having a major impact on social infrastructure. Therefore, preemptive flood measures and rapid initial response are crucial. The removable flood barrier "Flood Stopper" is designed to be lightweight, weighing about 3 kg per meter of panel, allowing for quick installation by a small number of people. Its unique double-lock structure provides high flood prevention performance, and impact resistance tests simulating actual disasters have been conducted. It is also used in facilities that require high reliability, such as international airports and hangars. Additionally, by using the flood sensor "KAMEKER," flooding during late-night hours or holidays can be immediately notified via LINE or email, supporting rapid initial responses from relevant parties. 【Usage Scenarios】 - Critical facilities such as substations and power plants - Flood prevention for underground facilities and parking garages - Protection of equipment around rivers and waterways - Protection of electrical rooms, mechanical rooms, and power receiving and transforming equipment 【Implementation Effects】 - Reduction of flood damage - Decrease in the risk of equipment shutdown - Reduction of recovery time and costs - Strengthening of BCP measures
basic information
【Features】 - Lightweight design at approximately 2.8 kg per panel, reducing the burden of installation work. - A locking mechanism at two points, the top and front, achieves high water resistance (equivalent to JIS standard water immersion prevention performance grade WS-6). - The aluminum extrusion structure ensures strength while remaining lightweight. - The back support (diagonal material) effectively withstands water pressure and impact. - The maximum water resistance height is 2 meters, and by using intermediate columns (joint columns), even higher water resistance can be achieved. 【Our Strengths】 Asahi Construction Co., Ltd. has gained strong trust from public institutions such as the Tokyo Metropolitan Government, Edogawa Ward, Katsushika Ward, the Tokyo Metropolitan Police Department, the Kanto Finance Bureau, and the Tokyo Housing Supply Corporation, primarily focusing on public works.
