PURPOSE:To enhance the working efficiency by providing a large diameter section to the tip of a double pipe and, at the same time, providing a nozzle provided with a spouting-port of a crushing agent to make hydration reaction and an air suction-port to fill successively the crushing agent having a specific particle size from the bottom of the crushing hole. CONSTITUTION:A large diameter section 14 is provided to the tip of a double pipe 12 and, at the same time, a nozzle C provided with a spouting port 5 spouting a crushing agent having a particle size of 0.1-20mm of crude lime, etc., and an air suction-port 6 is provided. A required number of crushing holes 16 are bored in a crushed matter 15 such as concrete or rock, etc. After that, the nozzle C is inserted into the crushing hole 16, the hole 16 is blockaded with the large diameter section 14, the crushing agent 17 is successively filled from the bottom of the hole 16 through the spouting port 5 and, at the same time, air in the hole 16 is absorbed by the suction port 6. It is reacted to water to make cracks in the crushed matter 15. According to the constitution, work can be efficiently carried out.
