Bridge demolition using blasting. By toppling the tall bridge piers, we connect to a safe mechanical dismantling process on the ground.
A bridge spanning National Route 417 in Ibigawa Town, Ibi District, Gifu Prefecture. Following the collapse of the steel girder bridge in the superstructure, blasting methods were also adopted for the dismantling of the bridge piers in the substructure. - Structure: Reinforced concrete (thickness 40 cm, hollow section) - External dimensions: 9 m × 4 m × height 21.6 m By blasting and crushing the base of the bridge pier into a wedge shape, the pier is made to topple onto the work floor, facilitating a safe mechanical dismantling process on the ground. [Features] - No need for large heavy machinery with long booms - The shape after toppling is relatively stable, allowing for smooth subsequent mechanical dismantling - Improved safety, reduced construction time, and cost savings are expected - Cracks in the concrete occur due to the impact during toppling, aiding in the subsequent mechanical dismantling *For more details, please refer to the PDF document or feel free to contact us.

Company information
Since its establishment, our company has consistently contributed to various types of demolition and renovation work, primarily focusing on the dismantling of explosives. In the renovation of blast furnaces at steel mills, we efficiently dismantle extremely hard residual slag, which poses challenges due to high temperatures, using our unique blasting technology. We have received high praise from clients regarding the construction period and safety. Additionally, in urban areas, we are actively researching new explosive materials in collaboration with our affiliated company, China Chemical & Pharmaceutical Co., Ltd., to enable safe and effective blasting operations, and we are committed to their implementation and dissemination.
