Abstract
The present invention relates to rig, particularly relate to a kind of drawing out soil equipment of hydraulic drill rig.The overall drawing out soil equipment of a kind of pilum stake dry type, it comprises a cylindrical shell, and this cylindrical shell is connected to drilling rod lower end, and it also comprises: a hydraulic jack, and its cylinder body end is fixedly connected on drilling rod inside, and its piston end passes in described cylindrical shell, and piston is slidably connected in cylindrical shell.The present invention can complete major diameter post pile hole construction fast, and ensures the dried and clean of job site.
Description
Technical field
The present invention relates to rig, particularly relate to a kind of drawing out soil equipment of hydraulic drill rig.
Background technology
Current, stanchion aperture is growing, and diameter has been very common in the hole of 400-1200mm.For large diameter hole like this, traditional approach is with drill hole of drilling machine, underground mud, rock layers is broken into block, and is filled with water formation mud, is discharged by mud by direct circulation system; Or rig rotary cutting, cuts into block earth, a general penetraction depth and equipment diameter ratio can not more than 1:1, and it is unearthed and throws away clod by swing equipment.
For the former mode, the mud of discharge can pollute construction plant, causes filthy job site; For the latter, rig inefficiency and equipment is easily impaired.
Summary of the invention
The present invention is intended to the above-mentioned defect overcoming prior art, provides a kind of pilum stake dry type overall drawing out soil equipment.The present invention can complete major diameter post pile hole construction fast, and ensures the dried and clean of job site.
The present invention is achieved in that the overall drawing out soil equipment of a kind of pilum stake dry type, and it comprises a cylindrical shell, and this cylindrical shell is connected to drilling rod lower end, it also comprises: a hydraulic jack, its cylinder body end is fixedly connected on drilling rod inside, and its piston end passes in described cylindrical shell, and piston is slidably connected in cylindrical shell; The draw ratio of described cylindrical shell is greater than 2:1.
The described overall drawing out soil equipment of subgrade stanchion hole dry type, described cylindrical shell is connected one end and is provided with six square joints with drilling rod, on it, cover has spring.
The described overall drawing out soil equipment of subgrade stanchion hole dry type, described cylindrical shell appearance is provided with thread groove.
The described overall drawing out soil equipment of subgrade stanchion hole dry type, described cylindrical shell bottom is provided with the drill bit that fetches earth.
The described overall drawing out soil equipment of subgrade stanchion hole dry type, described drilling rod is telescopic drill rod.
The described overall drawing out soil equipment of subgrade stanchion hole dry type, the cylinder body of described hydraulic jack is fixed in interior one deck drilling rod.
The described overall drawing out soil equipment of subgrade stanchion hole dry type, the two bottom sides of each section of drilling rod of described telescopic drill rod is equipped with the erection device of power conduit.
The present invention waits in use by getting core method, namely cylindrical shell is pressed into stratum, then mentions cylindrical shell, and dregs is lifted to more than ground in the lump with cylindrical shell, utilizes hydraulic jack dregs can be ejected.Because cylindrical shell height can reach several meters, therefore once can dig several meters down, greatly high jump drilling efficiency.Use of the present invention avoids water-filling, and the earthwork of digging out can directly be transported, or uses as backfill at the scene, avoids the phenomenon of job site mud crossing current, than conventional method more environmental protection.
