Description

Technical Field

[0001] The utility model relates to the technical field of engineering blasting, and is a pre-splitting blasting energy-gathering tube device. Background Art

[0002] When the explosive explodes in the blasthole, it will generate a strong shock wave and high-pressure gas and violently impact the rock mass around the blasthole wall, causing the surrounding rock mass to break and crack. When excavation blasting is carried out within a limited contour range, such as excavation of open-pit mines, building foundation pits, road cuttings and trenches, tunnels and underground building excavation, on the one hand, it is required that the boundary of the blasting excavation should be consistent with the designed contour line as much as possible, and over-excavation and under-excavation should not occur; at the same time, it is also required that the rock mass on the excavation boundary can be kept as intact and stable as possible. Pre-splitting (smooth surface) blasting is a blasting technology used to achieve the above purpose.

[0003] However, due to the single variety of finished small-diameter cords in my country and the lack of ready-made explosives that can be directly used for pre-splitting blasting and smooth blasting, the blasting devices commonly used for pre-splitting and smooth blasting near the edge of the embankment in China are primitive blasting devices in which workers bundle small-diameter cords and detonating cords on bamboo strips. It takes a lot of time for workers to load such blasting devices, and the bamboo strips are prone to move and tilt in the blasthole, resulting in unsatisfactory blasting effects. Summary of the invention

[0004] The utility model provides a pre-splitting blasting energy-gathering tube device, which overcomes the above-mentioned deficiencies of the prior art and can effectively solve the problems of inconvenient charge loading and unsatisfactory blasting effect in the prior pre-splitting blasting device.

[0005] The technical solution of the utility model is achieved through the following measures: a pre-splitting blasting energy-gathering tube device, comprising a tray and an energy-gathering tube, a rectangular plug is fixedly installed at the center of the upper part of the tray, a left-right through-card slot is arranged at the lower end of the energy-gathering tube, the card slot is rectangular, the width of the plug is consistent with the width of the card slot, the plug is arranged in the card slot, a front-to-back through-opening is opened at the front end of the energy-gathering tube, the length of the opening is consistent with the length of the energy-gathering tube, and a plurality of front-to-back through-energy-gathering holes are arranged at intervals at the upper and lower parts of the rear part of the energy-gathering tube.

[0006] The following are further optimizations and / or improvements to the above utility model technical solution:

[0007] The above may also include a top plate, a circular hole penetrating from top to bottom is opened in the center of the top plate, and the upper end of the energy-gathering tube is fixedly installed inside the circular hole.

[0008] A positioning groove may be provided at the upper end of the top plate, and the positioning groove is in the shape of an isosceles triangle.

[0009] The energy-gathering tube, tray and top plate can all be made of PVC material.

[0010] The diameter of the energy-gathering holes may be 10 mm to 15 mm, and the hole spacing between adjacent energy-gathering holes may be 20 mm to 25 mm.

[0011] The utility model has a reasonable and compact structure and is easy to use. A plug and a slot are provided, and the width of the plug is consistent with that of the slot. When installing, the plug on the upper part of the tray is arranged in the slot, so that the energy-gathering tube can be fixed at the center of the tray to prevent the energy-gathering tube from shifting. When charging, a detonating cord is laid on one side of the energy-gathering tube near the energy-gathering hole, and then a charge is inserted from the upper end of the energy-gathering tube, so that the charge can be installed conveniently and quickly. A front-to-back through-opening is provided at the front end of the energy-gathering tube, and a plurality of front-to-back through-energy-gathering holes are provided at intervals at the upper and lower parts of the rear part of the energy-gathering tube, so that an energy-gathering effect can be generated during blasting, and the blasting effect in the axial direction of the hole when the explosive explodes can be enhanced, and the problems of inconvenient charging and unsatisfactory blasting effect existing in the existing pre-splitting blasting device can be effectively solved.
