Highly locate positioned at 1/2 cone-shaped block；The thickness of cutting ring wall 22 is 2.7cm；It is described to cut native blade 23 as internal diameter 30cm, height
10.1cm, cone outer rim are 15 degree with interior diameter and arc surface vertical angle.
Specifically the process of fetching earth is：Fetch earth scene, earth pillar cylinder 14 is horizontal positioned, and one end is positioned over earth pillar upper end sleeve 12
Interior, the other end is placed in drilling pipe structure 2, rear rotation force cylinder 11, drilling pipe structure 2 and force application structure 1 is connected firmly, form one
It is overall, then cutting ring structure 3 is spun to the tail end of drilling pipe structure 2, assembly is completed, and single unit system is slowly upright, in gravity
Soil under action column casing 14 is slid be placed on supporting spring 20 downwards, and earth pillar upper end sleeve 12 is snapped down on bottom tray 13 with earth pillar cylinder 14.
Then, force handle 4 is pressed vertically downward, and now pressure is with force handle 4, holding force axle 6, holding force disk 7, connection rib 8, force cylinder
11st, drilling pipe 15, cutting ring structure 3 are transmitted downwards, are cut native blade 23 under pressure and are advanced to incision soil, when force column 10 rises
When being in close contact as force transmiting disk 9, continue to be pressed downward the handle 4 that exerts a force, after the bottom of drilling pipe structure 2 is buried, force handle 4 is pressed
Power is the thrust that turns clockwise, and rotates drilling pipe structure 2, and native advance is eaten in rotation, when more than drilling pipe ground remaining height in force application structure 1
Spend for 10cm when, stop drilling；Inverse time rotation force handle 4, drilling pipe 15, which is unearthed, above to be carried, and cutting ring structure 3 is lifted up therewith, when
When drilling pipe structure 2 is unearthed completely, device is manually carried away, is unscrewed, force application structure 1 and drilling pipe structure 2 are successively laid down, in cutting ring
Under the support of structure 3, earth pillar cylinder 14 is placed into design specified location.
For newly enclosing the extra large hydraulic reclamation strand barged-in fill of 2 years, internal diameter 30cm, depth 1.5m earth pillar cylinder 14, with tradition are gathered
" rammer ", " digging " method, single earth pillar need 4 it is artificial, work 4.5 hours, it is single by the 20 yuan of calculations of everyone hourly rate
Earth pillar fetches earth 360 yuan of cost；Using the quick drawing out soil equipment of the present invention, 3 i.e. collections in artificial 38 minutes are completed, and single earth pillar fetches earth
Cost is 38.0 yuan, and compared with conventional method, the quick drawing out soil equipment of soil column of the present invention used time of fetching earth saves
85.9%, but the cost that fetches earth is only the 10.6% of conventional method, it is quick, cost is cheap, significant effect.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
