Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
As shown in figs 1-9, it is one of a kind of pile pore-forming filling stake device for soil-slope model test of the present invention
Internal structure schematic diagram and use principle figure in embodiment, figure are to eliminate the schematic diagram of 1 one sides of sleeve, bag
Include：
Sleeve 1, framework 2 and cutter 3.Sleeve 1 is traditionally arranged to be retaining wall molding formula, up and down perforate, all round closure, framework 2
Internal structure can be inserted by top perforate, it is simple and practical again as stake molding shell is filled both as the retaining wall for cutting soil excavation.
Framework 2 is engaged with the interior shape of sleeve 1 inside sleeve 1, can be close to the inwall of sleeve 1, and being capable of edge
Sleeve 1 slides axially, and the top edges size of framework 2 is more than the madial wall size of sleeve 1, relative with sleeve 1 for fixed frame 2
Position, prevents the excessively downslide of framework 2, and convenient taking-up.
Cutter 3 is located at the bottom of framework 2, is hinged, is additionally provided between cutter 3 and framework 2 with the bottom of framework 2 by articulated elements 4
Elastic recoil device so that each blade 5 in cutter 3 can only along jointed shaft inside framework 2 from vertical with the side of framework 2
Position is arrived rotated between the side parallel position of framework 2 upwards, and the side of cutter 3 is vertical with the side wall of framework 2 in a free state, and
Each blade 5 in cutter 3 is capable of the bottom surface of covering framework 2, and can lift the soil of top.Complete after the cutting soil body, carrying
During drawing, cutter 3 is by the spring return initial angle of elastic recoil device, and then the bottom surface of closed frame 2, will can cut
The soil body is lifted to beyond sleeve 1, is completed soil excavation, is prevented collapse hole.
It is preferred that, sleeve 1 is four-prism shape sleeve, and its practicality is most extensive.
It is engaged with the above-mentioned structure of sleeve 1, framework 2 is also four-prism shape, including chassis body 6, ribs 7 and bottom
Fixed plate 8, ribs 7 are uniformly located at the top surrounding of chassis body 6, the two ends respectively top margin of connection framework main body 6 and side
Side, for stiffening frame main body 6.Rectangular bottom fixed plate 8 is located at the surrounding of the side lower end of chassis body 6, its major axis and frame
The base of frame body 6 is parallel, reinforcement effect is played to the bottom of chassis body 6, and provide connecting platform for cutter 3.Framework master
The size of the top margin of body 6 is more than the size of the inwall of sleeve 1, prevents the excessively downslide of framework 2, and convenient taking-up.
With the respective outer side edges of said frame 2, cutter 3 includes the blade 5 that four are equilateral triangle, and blade 5 is close to frame
The part of the axis of frame body 6 is equilateral triangle, is rectangle close to the part of bottom fixed plate 8, the long side of rectangular segment with
The base length of equilateral triangle part is consistent, after the bond length of rectangular segment is parallel with the side wall of framework 2 with blade 5 between
It away from consistent, will not mutually stop between blade 5 in upset, ensure that blade 5 can be turned to parallel with the side of framework 2, this
Sample will certainly leave a blank on the coverage rate of blade 5, and this, which leaves a blank, is distributed in the corner of the coverage rate of blade 5, but in upward band soil
When, these are left a blank substantially will not be to the soil that falls in the presence of soil pressure, and therefore, native process will not be put forward to cutter 3 by leaving a blank
Impact.The base of blade 5 is hinged with bottom fixed plate 8 by articulated elements 4, and is additionally provided with elastic recoil device between the two,
The shape that four blades 5 are constituted after merging to the axis of chassis body 6 is consistent with the bottom shape of chassis body 6.Cutter can be in dress
Put and the soil body is cut when moving down, it is to provide support platform for the soil body in framework 2 that can also move on the frame 2, facilitates the soil body to export
Outside device.
It is preferred that, elastic recoil device is some equally distributed torsionsprings 9, and its is simple in construction, easy to use, can be with
Torsionspring 9 is changed according to different use demands, use cost is reduced.The spring supporting of torsionspring 9 respectively with blade 5
And the bottom fixed plate 8 corresponding with blade 5 is connected, the spring body and articulated elements 4 of the torsionspring 9 on same one side are coaxial
Set, be conducive to the rotational action of blade 5.
Further, torsionspring 9 is spaced apart with articulated elements 4, and the uniform force of blade 5, stability in use is good, and intensity is more
It is high.
Use process：
A, by the framework 2 with cutter 3 from the top insertion sleeve 1 of sleeve 1, complete the assembly of whole device.
When B, excavation, by device as design stake position earth's surface, apply pressure, make the stress of cutter 3, blade 5 therein is overturn,
Parallel to the side wall of framework 2, there is shear action on the base of blade 5 and sleeve 1 to the soil body, and whole device is pressed into soil layer to setting
Buried depth is counted, stops pressurization.
C, then, keeps sleeve 1 motionless, framework 2 is lifted upwards, slow to extract out beyond sleeve 1, passes through torsionspring 9
Elastic force makes blade 5 be flipped back to original position, closes bottom surface, and the cutting soil body is leaked to beyond sleeve 1 with lifting from the side of framework 2.
Surflaes in D, cleaning eye, stake is filled into hole, after filling stake and reaching some strength, extracts soil around sleeve 1, densification out
Body, completes pore-forming and fills stake operation.
E, cleaning sleeve 1 and cutter 3, are re-assemblied, and continue aforesaid operations borehole.
After adopting the above technical scheme, the easy to get started simple to operate of device, smart structural design, possess excavation pore-forming and system
Mould fills two functions of stake；The structure of nested type ensure that internal borehole is unearthed, and outside retaining wall molding effectively prevents the periphery soil body from collapsing
Hole, it is to avoid cause the destruction of periphery soil body stability, substantially increase test accuracy；Structure is easily assembled, separates, and is easy to slagging-off
It with cleaning, can be reused, improve test efficiency.
