<p>PURPOSE: An explosion volume expansion type rock bolt and a reinforcing construction method using the same are provided to obtain a sufficient fixing force of a foundation by increasing the fixing force of a metal pipe because a volume of the metal pipe can be expanded with an explosion force. CONSTITUTION: An explosion volume expansion type rock bolt (100) comprises an explosion unit (110), a metal pipe unit (120), a first sealing unit (130), and a second sealing unit (140). The explosion unit is exploded when power is applied, and an explosion material is filled in an inner space in order to generate an explosion force. An external diameter of a body is expanded in the inside of a bore hole in the explosion of the explosion unit inserted into an arrangement hole so that the volume of the metal pipe unit is expanded. A first drawing hole is formed by penetrating the first sealing unit, and the first sealing unit seals an inlet. A second drawing hole is formed by penetrating the second sealing unit, and the second sealing unit is assembled in an end in order to cover the first drawing hole.</p> |
