| titleOfInvention | Injection apparatus of expansion type crushing material and rock excavation method using expansion type crushing material and crusher |
| abstract | The present invention relates to an intumescent crusher injection device and a rock excavation method using an intumescent crusher and a crusher, and the fluid crusher can be easily injected into the crushing material filling hole, and the intumescent crusher and the crusher are used in combination during rock excavation By doing so, the purpose is to make it possible to crush the rock with almost no vibration and noise. The crushing material injection device of the present invention for achieving the above object, the mixer 40 for mixing the crushing material in the powder state and water, and a cylindrical rubber cap inserted into the inlet of the crushing material filling hole (h) (10), a crushing material injection gun 20 coupled to the inner circumferential surface of the cylindrical rubber cap 10, and a crushing material inserted into the crushing material injection gun 20 to supply a fluid crushing material A tube pump 50 provided in the transfer pipe 30 and the crushing material conveying pipe 30 line for injecting crushing material, and an excess crushing material after filling the crushing material filling hole (h) with the crushing material It is characterized in that it is configured to include a crushing material circulation transfer pipe (30a) for circulation to the mixer (40). |
