Abstract

The invention discloses a plasma pulse rock breaking pile machine, and relates to the technical field of pile foundation construction. The plasma pulse rock breaking pile machine comprises a pulse discharging mechanism, a circulating mechanism and a drill bit connected with the pulse discharging mechanism, wherein the pulse discharging mechanism outputs high-voltage pulses to the drill bit to enable the drill bit to generate high-voltage arcs, and the circulating mechanism is used for conveying electrolyte to the drill bit and pumping mud generated by drilling out of a pile foundation. The plasma pulse rock breaking pile machine is based on a plasma rock breaking technology, rock breaking is achieved through arc energy through cooperation of the pulse discharging mechanism and the drill bit, and compared with mechanical rock breaking in the prior art, the plasma pulse rock breaking pile machine is simple in structure, capable of achieving the purpose of rapid pile driving and hole forming, and has the advantages of being small in mechanical abrasion, high in working efficiency, and adaptive to rock strata with different hardness.

Description

technical field

[0001] The invention relates to the technical field of pile foundation construction, in particular to a plasma pulse rock breaking pile machine. Background technique

[0002] Traditional pile foundation construction basically uses rotary drilling rigs, electro-hydraulic pile drivers, impact vibrating hammers, etc. for mechanical rock breaking or manual drilling. When drilling soft rock and medium-hard rock formations, rotary drill bits with cemented carbide cutters are usually used for drilling; when drilling medium-hard rock formations and above, milling tooth roller cone bits are usually used for drilling; When drilling into rock, diamond drill bits or steel grain drill bits are usually used for drilling; while for hard and brittle rock formations, hydraulic (pneumatic) in-hole impactors or insert drill bits are usually used for drilling.

[0003] The rock drilling equipment in the prior art has a complex mechanical structure, low working efficiency, and c...
