Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in figs 1-9, filling an embodiment of stake device for a kind of pile pore-forming for soil-slope model test of the present invention, internal structure schematic diagram and use principle figure in figure are all at the schematic diagram eliminating 1 one sides of sleeve, including:
Sleeve 1, framework 2 and cutter 3.Sleeve 1 is traditionally arranged to be retaining wall molding formula, upper and lower perforate, all round closure, and framework 2 can be inserted internal structure by top perforate, both as the retaining wall cutting soil excavation, again as filling stake molding shell, simple and practical.
It is internal that framework 2 is located at sleeve 1, matches with the interior shape of sleeve 1, it is possible to be close to sleeve 1 inwall, and can slide axially along sleeve 1, framework 2 top edges is sized larger than sleeve 1 medial wall size, for the relative position of fixed frame 2 with sleeve 1, prevent framework 2 from excessively gliding, and convenient taking-up.
Cutter 3 is located at bottom framework 2, by articulated elements 4 and framework 2 bottom-hinged, elastic recoil device it is additionally provided with between cutter 3 and framework 2, each blade 5 in cutter 3 upwards can only be rotated from the position vertical with framework 2 side along jointed shaft in framework 2 inside to the parallel position of framework 2 side, cutter 3 side is vertical with framework 2 sidewall in a free state, and each blade 5 in cutter 3 can cover the bottom surface of framework 2, and the soil of top can be mentioned.After completing the cutting soil body, in lift process, the cutter 3 spring return initial angle by elastic recoil device, and then the bottom surface of closed frame 2, by beyond cutting soil body lift to sleeve 1, soil excavation can be completed, it is prevented that collapse hole.
Preferably, sleeve 1 is four-prism shape sleeve, and its practicality is the most extensive.
Match with above-mentioned sleeve 1 structure, framework 2 is also four-prism shape, and including the fixing plate 8 in chassis body 6, ribs 7 and the end, ribs 7 is located at chassis body 6 top surrounding uniformly, two ends connect top margin and the side of chassis body 6 respectively, for stiffening frame main body 6.The surrounding of lower end, chassis body 6 side is located at by fixing plate 8 at the rectangular end, and its major axis is parallel with the base of chassis body 6, to playing reinforcement effect bottom chassis body 6, and provides connecting platform for cutter 3.The size being sized larger than sleeve 1 inwall of chassis body 6 top margin, it is prevented that framework 2 excessively glides, and convenient taking-up.
With said frame 2 respective outer side edges, cutter 3 includes four blades 5 being equilateral triangle, blade 5 is equilateral triangle near the part of chassis body 6 axis, the end of near, the part of fixing plate 8 is rectangle, the long limit of rectangular segment is consistent with the base length of equilateral triangle part, spacing after the bond length of rectangular segment is parallel with framework 2 sidewall with blade 5 is consistent, will not mutually stop between blade 5 when upset, ensure that blade 5 can be turned to parallel with framework 2 side, so will certainly leave a blank to some extent on the coverage rate of blade 5, this leaves a blank and is distributed in the corner of blade 5 coverage rate, but when upwards band soil, these are left a blank under the effect of soil pressure substantially without native to falling, therefore, leave a blank and the soil process that carries of cutter 3 will not be impacted.The base of blade 5 is hinged by articulated elements 4 with the fixing plate 8 in the end, and is additionally provided with elastic recoil device between the two, and the shape that four blades 5 form after merging to chassis body 6 axis is consistent with chassis body 6 bottom shape.Cutter can cut the soil body when device moves down, it is also possible to moving on the frame 2 is provide for the soil body in framework 2 to support platform, facilitates outside soil body output device.
Preferably, elastic recoil device is some equally distributed torsionsprings 9, and its simple in construction is easy to use, it is possible to change torsionspring 9 according to different user demands, reduces use cost.The spring supporting of torsionspring 9 is connected with the fixing plate 8 of blade 5 and the end corresponding with blade 5 respectively, and the spring body of the torsionspring 9 being positioned on together is coaxially disposed with articulated elements 4, is conducive to the rotational action of blade 5.
Further, torsionspring 9 is spaced apart with articulated elements 4, and blade 5 uniform force, stability in use is good, and intensity is higher.
Use procedure:
A, by the framework 2 with cutter 3 from sleeve 1 sleeve 1 inserted above, complete the assembly of whole device.
When B, excavation, by device as design earth's surface, stake position, apply pressure, making cutter 3 stress, blade 5 therein overturns, and is parallel to the sidewall of framework 2, the soil body is all had shear action by the base of blade 5 and sleeve 1, whole device is pressed into soil layer to designing buried depth, stops pressurization.
C, subsequently, keeps sleeve 1 motionless, is upwards lifted by framework 2, slowly extracts out beyond sleeve 1, makes blade 5 be flipped back to original position by torsionspring 9 elastic force, closes bottom surface, and the cutting soil body leaks to beyond sleeve 1 from the side of framework 2 along with lift.
Surflaes in D, cleaning eye, fills stake in hole, after filling stake and reaching some strength, extracts sleeve 1, densification surrounding soil out, completes pore-forming and fills stake operation.
E, cleaning sleeve 1 and cutter 3, re-assembly, continue aforesaid operations borehole.
After adopting technique scheme, the simple to operate easy left-hand seat of device, smart structural design, possess excavation pore-forming and fill two functions of stake with molding；The structure of nested type ensure that internal borehole is unearthed, and outside retaining wall molding effectively prevents periphery soil body collapse hole, it is to avoid cause the destruction of periphery soil body stability, substantially increase test accuracy；Structure is easily assembled, separable, it is simple to slagging-off and cleaning, can be repeated utilizing, improve test efficiency.
