By adjusting the type of explosives used, the amount of charge, and the blasting pattern, it is possible to fragment according to the scale suited to the site conditions.
■The technology that utilizes the explosive energy of explosives has been widely used in mining and civil engineering for a long time, and can be considered an economical and efficient method. By effectively utilizing the powerful explosive energy of explosives, significant effects can be achieved. ■Since it is possible to eliminate the use of breakers, the noise and vibration burden on the surrounding area can be reduced. ■When applying blasting methods as an auxiliary to breakers and crushers, it is possible to select the type of explosives used and adjust the blasting pattern, allowing for a reduction in the workload of breakers and crushers by any desired ratio. ■Compared to traditional demolition work using heavy machinery, it becomes possible to reduce the operating time of heavy machinery, thereby decreasing fuel consumption. This makes it possible to reduce CO2 emissions generated during construction.

Detailed information
-
The RC building foundation will be shattered into pieces. The bucket alone can handle the debris. ■Water-containing explosives will be used.
-
Localized crushing of the RC structure (columns, beams, slabs, walls, stairs) will be performed. ■ Using small-diameter water-containing explosives.
-
We crush ripple concrete made of reinforced concrete into block shapes. We can divide it into sizes according to the capacity of heavy machinery. ■ Using high-performance devices (with the setting of electronic delay detonators (EDD), it is possible to control the detonation time in units of 1 millisecond (1/1,000 seconds) according to the site conditions, which allows for the reduction of noise and vibration through wave separation and interference.)
-
If permission to use explosives cannot be obtained, or if it is not possible to wait for permission to use explosives due to urgent construction, it is possible to respond quickly by using non-explosive demolition agents that are not subject to the Explosives Control Law. ■ Use of non-explosive demolition agents
-
In remote islands where there is no distribution of explosives, it is possible to efficiently break rock and concrete using non-explosive demolition agents. ■Use of non-explosive demolition agents
-
We will crush fallen rocks and rolling stones that are obstructing the way. Since it is possible to transport materials manually, it can be applied in places where vehicles cannot pass (such as mountainous areas). It can also be utilized to secure routes during large-scale disasters such as earthquakes. ■Using small-diameter water-containing explosives.

Company information
Sagamiko Corporation plans, designs, constructs, and manages various types of demolition work, including the removal and disposal of asbestos-containing building materials. Additionally, by controlling the powerful destructive energy of explosives, we have adopted blasting methods for demolition work, particularly the mini blasting method, which actively reduces environmental impact on the surrounding area. The mini blasting method minimizes the use of heavy machinery, reduces fuel consumption, improves worker safety, shortens construction time, lowers costs, and significantly contributes to environmental improvements. Sagamiko Corporation will continue to meet customer needs based on the know-how and network developed through our accumulated experience.
