Anchor pile often is arranged in locations such as tunnel portal, barrel biass, such as Jiangxi Jiu Jingqu project thunder tor No.1 tunnel in battalion's safety
Shallow Section is because landform bias is seriously arranged 6 anchor piles, and new No. 2 tunnel portals of furnace are because landform bias is arranged 2 anchor piles, and tunnel
The construction speed of road anchor pile decides the speed of tunnel and the duration of constructing tunnel.For unit in charge of construction progress,
Duration is equal to benefit and cost.And consuming time is long for traditional bursting work anchoring pile constructing process, construction risk is high, often
Restrict the construction of tunnel main body.Even individual work points can not further be reduced because of the restriction of blasting environment using bursting work
Construction efficiency, increases construction cost, if furnace new No. 2 hole anchor piles are because close to provincial highway and passenger station, blasting environment is complicated,
It needs to carry out road closed and passenger station evacuating personnel if using blast working, otherwise can not carry out blast working, Jin Jindao
Road block and this expense of evacuating personnel cause cost wholesale to increase, the exactly almost impossible receiving of unit in charge of construction.
Utility model content
Purpose of the utility model is to solve the above-mentioned problems of the prior art, provide a kind of big section rectangle anchor
Gu pile rotary drilling rig rectangle die cut drill bit.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of big section rectangle anchor pile churning driven
Machine rectangle die cut drill bit, including rotary digging drill bit, rotary digging drill bit bottom are provided with rectangular box, and rectangular box includes rectangular top surface
With four rectangle sides, rectangular top surface is welded and fixed with four rectangle sides, and rotary digging drill bit lower surface is welded on rectangular box
Each rectangle sides bottom at the center of upper surface, rectangular box is provided with heel teeth.
Rectangular box is internally provided with reinforcing stull.
Diagonal brace is vertically arranged between the side of rotary digging drill bit and the upper surface of rectangular box.
At least provided with two heel teeths, heel teeth is welded on rectangle sides bottom using steel spring plate for each rectangle sides bottom
Portion.
There are two the reinforcing stulls at least, reinforces stull using A3 steel plate and is welded on box house.
There are four the diagonal braces, and diagonal brace is triangular steel plate diagonal brace, and a right-angle side of triangular steel plate diagonal brace is welded on
On rotary digging drill bit outer wall, on the diagonal line for the rectangular top surface that another right-angle side is welded on cabinet.
The utility model has the beneficial effects that: conjunction of the utility model using rotary drilling rig large torque cooperation different model
Golden drill bit efficient pore-forming can be met by the acquisition that repeatedly drills and be set using the combination of different model drill bit in the higher rock stratum of intensity
Desired anchor pile section and depth are counted, to evade artificial lower opening instead of traditional anchor pile human-generated explosives operation and apply
The security risk of work, while reducing panelling construction process, the construction efficiency of anchor pile pore-forming is substantially increased, anchoring is reduced
Pile driving construction cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the bottom substance schematic diagram of Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Embodiment 1
As depicted in figs. 1 and 2, the present embodiment provides a kind of big section rectangles to anchor pile rotary drilling rig rectangle die cut drill bit,
Including rotary digging drill bit 1,1 bottom of rotary digging drill bit is provided with rectangular box 2, and rectangular box 2 includes rectangular top surface and four rectangles

Center, each rectangle sides bottom of rectangular box 2 are respectively provided with there are three heel teeth 3, and heel teeth 3 is welded on rectangle using steel spring plate
Side bottom is uniformly arranged inside rectangular box 2 there are two stull 4 is reinforced, and is reinforced stull 4 using A3 steel plate and is welded on rectangular box
Inside body 2, it is vertically arranged between the side of rotary digging drill bit 1 and the upper surface of rectangular box 2 there are four diagonal brace 5, diagonal brace 5 is triangle
One right-angle side of shape steel plate diagonal brace, triangular steel plate diagonal brace is welded on 1 outer wall of rotary digging drill bit, and another right-angle side is welded on
On the diagonal line of the rectangular top surface of rectangular box 2.
Embodiment 2
The present embodiment provides a kind of big section rectangles to anchor pile rotary drilling rig rectangle die cut drill bit, including rotary digging drill bit 1, rotation
Dig 1 bottom of drill bit and be provided with rectangular box 2, rectangular box 2 includes rectangular top surface and four rectangle sides, rectangular top surface with
Four rectangle sides are welded and fixed, and 1 lower surface of rotary digging drill bit is welded on the center of 2 upper surface of rectangular box, the ruler of rectangular box 2
