One-step forming excavation drill bit for shallow square foundation pit

Abstract

The invention discloses an one-step forming excavation drill bit for a shallow square foundation pit. The shallow square foundation pit one-time forming excavation drill bit comprises a drill bit body, wherein a steel pipe is arranged on the outer side of the drill bit body, and a drill rod is arranged in the steel pipe; the drill bit body is provided with a connecting mechanism, a vibrating mechanism, a hydraulic device and a drill bit mechanism from top to bottom, the drill bit mechanism comprises a steel pipe, a lower end of the steel pipe is connected with a box body, reinforcing structures are arranged on the periphery of the connecting position of the box body and the steel pipe, a cavity is formed in the box body and the steel pipe, and a drill rod, an auger blade and a drill rod support are arranged in the cavity; an alloy blade is installed at the arc shape, air holes are formed in four corners of the box body, metal blocking pieces are arranged at lower ends of the air holes, and a quick connector is arranged at an upper end of the drill bit mechanism. The equipment can be applied to a series of fields such as street lamps, rain and sewage vertical shafts, greening nursery stocks, traffic lights, solar power generation panels, traffic signs, fence columns and the like in which shallow-layer square, circular and special-shaped foundation pits need to be excavated. The one-step forming excavation drill bit has advantages of one-time forming, no need of supporting a template, time saving, labor saving and material saving.

Description

technical field [0001] The invention relates to the field of engineering machinery and building foundation construction, in particular to a one-time forming excavation drill bit for a shallow square foundation pit. Background technique [0002] Traditional excavation drills cut soil and rock layers, and finally remove these cuttings through mud circulation or manual soil removal. The existing technology lacks targets for: street lamps, rainwater shafts, green seedlings, traffic lights , solar power generation panels, traffic signs, retaining columns and a series of technologies and equipment that need to excavate shallow square, circular and special-shaped foundation pits. Contents of the invention [0003] The technical problem to be solved by the present invention is that the prior art is short of aiming at: a series of excavated shallow square, circular, Special-shaped foundation pit technology and equipment. [0004] In order to solve the above technical problems, th...
