Description
Technical Field
The utility model relates to a liquid fills blasting arrangement structure based on pascal's law. Is applicable to the technical field of rock blasting.
Background
At present, blasting rock by explosives in the engineering field is usually carried out by firstly digging blast holes, putting the explosives in the blast holes, plugging orifices and detonating. The high temperature, high pressure gas generated by the explosive expands to cause the rock to break. However, due to the existence of gaps between the explosive and the blast hole, the actual energy utilization rate, the blasting efficiency and the blasting effect are poor, and the energy utilization rate of the broken rock of the explosive only accounts for about ten percent of the total energy of the explosive at present.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to solve the technical problem, the utility model provides an improve liquid filling blasting arrangement structure based on pascal's law of explosive energy utilization.
The utility model adopts the technical proposal that: a liquid-filled blasting arrangement based on pascal's law, characterized by: the explosive is arranged in the blast hole, force transmission liquid which is used for immersing the explosive and uniformly transmitting the impact force of the explosive to surrounding rock mass is poured, and the orifice of the blast hole is blocked. So, arrange the explosive in the big gun hole at the explosion in-process, evenly transmit the impact force that produces the explosive explosion for the rock mass around through biography power liquid, have better blasting effect.
The force transfer liquid is non-conductive and non-flammable liquid. So, can effectively avoid the spark that the blast hole produced because of the collision of lump stone and lead to the risk that the explosive explodes in advance, transformer oil burning consumed energy when also effectively avoiding the explosive to explode simultaneously increases the construction security among the rock mass blasting work progress.
The force transfer liquid is transformer oil or edible oil.
The force transmission liquid adopts non-Newtonian fluid. Thus, the force transmission property is better and the viscosity is higher.
And the force transmission liquid is filled in a closed space formed by the blocking plug in the blast hole. Therefore, the explosive is completely immersed in the force transfer liquid in the closed space, air is completely exhausted in the closed space, and the phenomenon that the inner wall of the blast hole is stressed unevenly due to the existence of bubbles during explosive explosion is avoided.
A rock blasting method applies the liquid filling blasting arrangement structure based on Pascal's law, and is characterized in that:
excavating and forming blast holes on the surface of a rock mass according to blasting design requirements;
arranging the explosive in the blast hole, and leading out a lead connected with the explosive to the outside of the blast hole;
arranging a rubber chuck on the inner wall of the blast hole between the opening of the blast hole and the explosive, and arranging the explosive in a closed space formed by plugging the rubber chuck;
opening a sealing element on the rubber chuck, filling the region between the chuck and the bottom of the blast hole with force transfer liquid through a liquid injection hole on the chuck, immersing explosive arranged in the blast hole, and closing the sealing element on the rubber chuck;
pouring concrete between the opening of the blast hole and the rubber chuck, and plugging the blast hole;
the explosive is detonated by a lead.
The utility model has the advantages that: because the liquid blasting stress transmissibility is better, the explosive consumption can be saved on the premise of ensuring the same blasting effect, thereby reducing the expensive explosive cost; the gap between the blast hole and the explosive is filled with liquid, so that energy consumption caused by compression of a part of explosive gas in the gap can be avoided, and the energy conversion efficiency is improved; the blasting acting force can be more uniformly transmitted to the rock, and the situation that after blasting is easily caused in the traditional blasting engineering, the size of broken rock is not uniform, and even secondary rock cracking is needed is avoided; because the acting force is more uniform, the controllability of blasting operation is higher, and unnecessary damage to surrounding buildings and rock masses is avoided; only one link for filling liquid is added, so that the construction is convenient, the efficiency is improved, and the construction period is not prolonged; the dosage of explosive is reduced, the environment is protected, and the influence on the surrounding environment is less.
