Demolition method "Mini Blasting Method"

basic information

【Application Range of Mini Blasting Method】 ■ In places where heavy machinery cannot be brought in ■ At sites where breakers cannot be used ■ In locations where regulations on construction nuisances such as noise, vibration, and dust are strict ■ For large structural components and structures that cannot be crushed by a crusher (including the processing of stones, etc.) ■ For partial demolition or renovation work on structures ■ As an alternative method to breaker methods, static crushing agent methods, core boring methods, cutter methods, wire saw methods, hydraulic rock splitting methods, etc. ■ For the demolition of underground installations (such as water tanks and septic tanks) ■ For crushing foundations and other structures on supporting ground that should not be damaged ■ At sites where structures that should not be damaged are adjacent ■ For partial demolition of structures such as columns, beams, walls, and floors in renovation work ■ At sites where there is a desire to reduce the burden on the surrounding environment ■ At sites where construction periods and conditions (noise, vibration, safety, etc.) are restricted ■ At sites where the direction of crushing and the size of crushed pieces need to be controlled ■ At sites where there is a desire to improve working environments that may pose health risks etc. *For more details, please download the PDF or contact us.

Detailed information

• 

  Crushing of column members using the mini blasting method By loading a small amount of mini blasting explosives at appropriate positions of RC members (columns, beams, slabs, walls, etc.), it is possible to finely control the crushing range.

• 

  Crushing of underground foundations using mini blasting methods By loading small explosives along the desired line for breaking and dividing the underground foundation, it is possible to split the foundation into block shapes and sequentially remove the block pieces with heavy machinery.

• 

  Crushing of underground foundations using blasting methods Underground foundations that have been crushed by blasting (typically using explosives) can be easily removed with a bucket. The dismantling and removal of the underground foundations can be completed without using any breakers.

• 

  Crushing of RC members using non-explosive demolition agents Non-explosive demolition agents do not require consumption permits from prefectures, unlike explosives, allowing for responsiveness to unexpected construction work.
