New crack measurement system [Dam measurement]
New crack measurement system for dam measurement
It is possible to measure the width, position, and length of cracks with high precision from a distance. This is a groundbreaking measurement system that breaks conventional wisdom.
Concrete structures such as bridges, tunnels, and building exteriors require a tremendous amount of cost and time for crack inspections. With 'KUMONOS', cracks can be measured from a distance, eliminating the need for scaffolding or aerial work platforms during exterior inspections, allowing for safe evaluations. It is a groundbreaking measurement system that breaks the conventional wisdom of crack inspections. 'KUMONOS' has won the 11th National Land Technology Development Award and received the Minister of Education, Culture, Sports, Science and Technology Award for Scientific and Technological Achievement (Development Category).

Detailed information
-
Dam Field work: 14 personnel Quantity: 6,700 square meters (embankment 4,600 square meters, diversion wall 1,220 square meters, spillway 480 square meters, guardrail section 400 square meters) KUMONOS is effective for measuring dams where it is difficult to set up scaffolding. Measurements were taken from a distance of approximately 100 meters, not only for cracks but also for the shape of deterioration areas such as spalling, free lime, and exposed aggregates.
Company information
Our company was founded in 1995 with the aim of supporting the recovery from the Great Hanshin-Awaji Earthquake. The company name is derived from our unique measurement device "KUMONOS," which can quickly and accurately measure 0.2mm cracks from a distance of 100 meters. In 1998, we were the first in Japan to introduce a 3D laser scanner, and since then, we have developed 3D measurement and equipment introduction businesses to promote 3D laser scanner technology. Over the past 25 years, we have accumulated over 2,500 measurement achievements and approximately 300 equipment introductions, establishing ourselves as a leading company in 3D laser scanning in Japan. Our technology has received numerous ministerial awards from the Ministry of Land, Infrastructure, Transport and Tourism, the Ministry of Economy, Trade and Industry, and the Ministry of Education, Culture, Sports, Science and Technology, including the Japan Manufacturing Award. Additionally, our technology was introduced to world leaders at the G20 Osaka Summit, receiving high praise both domestically and internationally. Moving forward, we will continue to implement cutting-edge technology backed by our high technical capabilities and provide DX solutions across various fields.
