Rapid and silent rock breaking method

Abstract

The invention relates to a rapid and silent rock breaking method. The rapid and silent rock breaking method comprises the steps that 1), the range needing to be broken is drawn firstly, and then the drilling positions are marked; 2), drilling is performed; 3), heating cables are put into holes and are connected in series, and then the heating cables are sequentially connected with a temperature controller, a switch and a power source; 4), a mixed breaking agent is poured into the outermost row of holes, and the holes are covered with linen bags after pouring is completed; 5), the heating cables are electrified, and the breaking agent reaches the optimum reaction temperature stated in the specification; 6), the rock surface crack change condition is observed and recorded according to the set time period; 7), when rocks are broken to a certain degree and no longer change, the heating cables are closed, and rocks start to be cleaned; and 8), and the steps mentioned above are carried out till all the rocks are broken. According to the rapid and silent rock breaking method, the purpose of increasing the temperature in the holes through auxiliary heating and control of the temperature controller is achieved, the breaking agent is promoted to accelerate a hydration reaction, and therefore the purposes of rapid expansion and breaking are achieved, and the construction process is accelerated.

Description

Technical field [0001] The invention belongs to the technical field of building construction, and specifically relates to a method for rapid and silent rock breaking. Background technique [0002] At present, in the construction of engineering buildings, most of the underground rock formations are excavated by traditional large-scale machinery or explosives for blasting construction. This method causes great safety hazards to the surrounding environment and personnel. As a new type of demolition method, silent crushing agent is widely used because it does not produce vibration, noise, flying rocks, dust and toxic gas when crushing rocks. It is a pollution-free and environmentally friendly product, not a flammable or explosive material. The transportation and storage are safe and reliable, and easy to use. The crushing effect of this product is stable. Generally, the rock can be broken within 12 hours. It is mainly used for concrete projects and rock projects that need to be de...

Problems solved by technology

However, when encountering a low temperature environment, if the breaking agent is poured directly, the reaction of the breaking agent will be insufficient, the breaking time will be too long, and the effect will be poor due to reasons such as too low temperature in the hole.

When the desired effect is achieved, it is necessary to re-drill the hole and refill the breaking agent, the construction progress is delayed, and the work efficiency is low
