Free membership registrationThe removal of aging bridges (superstructures, piers, abutments) is always accompanied by many challenges, such as the difficulty of mechanical demolition. The blasting technology that our company has refined over more than half a century allows us to use the minimum amount of explosives through meticulous blasting design, enabling the bridge to collapse and fall from a structurally stable state, thus facilitating a safe mechanical demolition process on the ground. In addition to blasting, we offer many demolition methods that can respond to various situations at each site. Bridges that have long contributed to regional development and people's interactions. Please entrust us with the final moments of a bridge filled with many memories. 【Features】 ■ No need for large-scale scaffolding, leading to shortened construction periods and cost reductions. ■ Significant reduction in high-altitude work that poses risks of falling or collapsing. ■ Reduction of approaches to bridges that are aging or at risk of collapse. ■ Reduction of load stress acting on the bridge during demolition work. ■ Significant improvement in safety. ■ Capable of accommodating various bridge structures. *For more details, please refer to the PDF materials or feel free to contact us.

Free membership registrationA bridge spanning National Route 417 in Ibi River Town, Ibi District, Gifu Prefecture. With the opening of a bypass due to the construction of new tunnels and bridges, the Shinkawajiri Bridge (the old bridge), built in 1961, has completed its 60-year service and was dismantled using blasting techniques. - Structure: Steel Langer Bridge - Bridge Length: 136.7 m - Width: 5.5 m - Weight: 223 tons On both sides of the bridge, steel components were cut using a V-shaped blasting line and dropped directly onto a work platform created on the riverbed of the Ibi River, facilitating a safe mechanical dismantling process on the ground. [Features] - Elimination of the need for large scaffolding, leading to reduced construction time and cost savings - Significant reduction in the risks associated with high-altitude work, including falls - Major reduction in the hazardous task of rigging heavy objects - No special equipment required due to the drop from its own weight - The form after the drop is relatively stable, allowing for smooth subsequent mechanical dismantling *For more details, please refer to the PDF document or feel free to contact us.*

Free membership registrationA 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 pier in the substructure. - Structure: Reinforced concrete (thickness 40 cm, hollow cross-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 anticipated - 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.

Free membership registrationThe "V-shaped shaped charge (Linear Shaped Charge)" is an explosive device for metal cutting that utilizes the Neumann effect (also known as the Monroe effect). It consists of a high-performance explosive filled within a metal sheath made of materials such as copper or lead, shaped into an inverted V cross-section. When detonated, the inverted V part of the metal sheath (the liner) transforms into a high-temperature, high-pressure, high-velocity jet due to the Neumann effect, instantly cutting through the target. In the dismantling of steel structures, it can effectively cut major columns and beams (steel materials), allowing for safe and efficient demolition work by causing them to topple and fall. 【Features】 ■ Simultaneous and instantaneous cutting at multiple locations ■ High cutting surface precision ■ Safe cutting operations through remote control ■ Expected labor savings, reduced construction time, and cost reduction ■ Reduction of CO₂ emissions by minimizing heavy machinery operation *For more details, please refer to the PDF document or feel free to contact us.

Free membership registrationThe "Super Bigger Method" is a technique for breaking and crushing hard rock and concrete structures with low vibration and low noise. It is particularly effective for construction near safety-related properties, as it poses minimal risk of flying debris. The crushing pressure can reach 3,400 tons, allowing for reliable fragmentation of hard rock. Additionally, it can be operated with a 0.8m³ class power shovel, enabling rotation during movement and setup, making it highly versatile even in narrow spaces. If a separate hydraulic power source is provided, it can also be suspended and operated with a crane. 【Features】 ■ Can crush with low vibration and low noise ■ Suitable for breaking medium to hard rock ■ Mounted on a general-purpose shovel (0.7m³), adaptable from narrow to wide spaces ■ Continuous operation possible with small bench cut method *For more details, please refer to the PDF document or feel free to contact us.

Free membership registrationThe "Mini Blasting Method" refers to a blasting technique that uses small-diameter, low-quantity high-performance explosives to achieve localized and small-scale destruction. Our company quickly recognized the effectiveness of this method, which had been used in Scandinavia, and has repeatedly conducted experiments aimed at practical application. As a result, we have realized a faster, cheaper, and safer blasting solution using small yet powerful explosives. This enables efficient and economical destruction in various scenarios at demolition sites. 【Features】 ■ Uses special protective sheets to effectively prevent flying debris ■ Reduces blasting noise and vibration by using low-quantity explosives ■ Effective for cases where "only this part needs to be destroyed" due to the ability for localized blasting ■ Does not cause damage to areas outside the planned destruction zone ■ Small-diameter blast holes allow for quick drilling operations *For more details, please refer to the PDF materials or feel free to contact us.
