Problems solved by technology

However, when hard rocks are encountered during piling, if the normal piling machine is used to continue the operation, the working time may be increased and the machinery may be seriously damaged
At the same time, increasing the strength of mechanical piling can also easily cause loosening and damage to the rock and soil in the non-target crushing area, affecting the quality and efficiency of the project

Abstract

The in-hole directional stone breaking device comprises a device shell, a high-voltage electric pulse assembly, a wire replacing assembly, a liquid explosive liquid injection assembly and an insulating material are arranged on the device shell, an inner cavity of the device shell is filled with the insulating material, and a sealing rubber ring is embedded in the position, close to the outer side, of the middle of the device shell. Parts of parts on the high-voltage electric pulse assembly, the wire changing assembly and the liquid explosive injection assembly are arranged in the device shell in an offset mode. The liquid explosive injection assembly injects liquid composite explosives into the to-be-blasted hole, and the injected liquid composite explosives are located below the sealing rubber ring. The directional rock breaking device is compact in layout, simple in using method, reliable in performance and convenient to maintain, directional rock breaking is achieved through the fan-shaped lower portion modeling, the rock breaking effect is improved by blasting metal wires through high-voltage electric pulses and triggering secondary explosion of liquid composite explosives, the blasting energy can be accurately controlled by adjusting stored electric energy and the explosive injection amount, and the rock breaking efficiency is improved. And discharge blasting can be continuously implemented for multiple times.

Description

technical field [0001] The invention relates to the technical field of pile driving and rock breaking, in particular to an in-hole directional rock breaking device using high-voltage electric pulses and a construction method thereof. Background technique [0002] Pile driving widely exists in bridges, buildings and other fields, mainly to enable the foundation of ground buildings to go deep into the ground and ensure sufficient rock and soil strength to support the building pressure. However, when hard rocks are encountered during piling, if ordinary piling machines are used to continue the operation, the working hours may be increased and the machinery may be easily damaged. At the same time, increasing the strength of mechanical piling can also easily cause loosening and damage to the rock and soil in the non-target crushing area, affecting the quality and efficiency of the project. Contents of the invention [0003] The purpose of the present invention is to provide an...
