The utility model provides a technical scheme that its technical problem adopted is: the energy-gathering pipe comprises an energy-gathering pipe, a buckle cover, a buffer layer, emulsion explosive and a detonating cord, wherein energy-gathering grooves are respectively arranged on the left side, the right side and the lower side of the energy-gathering pipe, the upper opening of the energy-gathering pipe is provided with the buckle cover, the emulsion explosive is arranged in the energy-gathering pipe, the buffer layer is arranged between the emulsion explosive and the buckle cover, and the detonating cord is arranged in the emulsion explosive.
The left end and the right end of the lower portion of the buckle cover are respectively provided with a buckle, the left side and the right side of the upper portion of the energy collecting pipe are respectively provided with a clamping groove, and the buckle of the buckle cover is clamped in the clamping groove in the upper portion of the energy collecting pipe.
The buffer layer is made of resin materials.
The size opening angles of the energy gathering grooves on the left side, the right side and the lower side of the energy gathering pipe are consistent.
The wall thickness of the energy collecting pipe is 1-2 mm.
The length of the energy gathering pipe is 3-5 cm.
The detonating cord is positioned in the center of the emulsion explosive.
The utility model discloses a tunnel is gathered can water pressure special three-dimensional of smooth surface blasting and is gathered can charging means compares with prior art, has following outstanding beneficial effect: the energy-collecting pipe can directionally explode and protect the tunnel surrounding rock through the energy-collecting grooves and the buffer layer, and the traditional assertion that the IV-grade surrounding rock and the V-grade surrounding rock cannot be subjected to smooth blasting is broken. Through setting up the buffer layer, guarantee that this energy-gathering pipe can combine the soft or hard and broken degree of country rock to carry out the adjustment of in good time charge, be applicable to different grades of country rock. Compared with conventional blasting, the energy-accumulating hydraulic pressure smooth blasting saves the explosive, reduces the dust concentration, shortens the blasting distance, improves the utilization rate of blast holes, and obtains good economic and social benefits.
