Abstract

A kind of novel land pebble specific drilling tool, be applicable to the drilling and forming hole in land pebble, it comprises drilling rod, helical blade, one end of drilling rod is provided with the buckle for being connected with rig, the other end of drilling rod is cone point, drilling rod is provided with helical blade, it is characterized in that rotating vane is provided with oval gyro cone.The utility model drilling tool can repeatedly use, cost-saving, and construction efficiency is high, saves the engineering time.

Description

A kind of novel land pebble specific drilling tool
Technical field
The utility model is applicable to the drilling and forming hole in land pebble, is specifically related to a kind of specific drilling tool of novel land pebble.It can also be applied to the cobble soil layer construction in the engineering field building grounds such as building construction, municipal administration, water conservancy and hydropower, petroleum and petrochemical industry, road and rail, processes the drilling tool in land pebble pore-forming and clear hole specifically in the basement process equipment of present stage.
Background technology
In land pebble filling pile construction, land pebble specific drilling tool is a kind of by flight with revolve head extrude cobble in land pebble, extracts cobble soil layer, the method for pore-forming in land pebble simple to operate.
Existing land pebble hole forming method adopts percussive drill impact holing, adopts mud off.The easy collapse hole of the method, borehole enlargement, waste a large amount of concrete, speed of application is slow.
Summary of the invention
In order to solve in land pebble not under retaining wall condition, form the hole of castinplace pile, ensure the problem of the construction of pore-forming in land pebble, the utility model provides a kind of construction drilling tool of land pebble.
The utility model is made up of buckle, drilling rod, helical blade, gyro cone, cone point, one end of drilling rod is provided with the buckle for being connected with rig, the other end of drilling rod is cone point, drilling rod is provided with helical blade, it is characterized in that rotating vane is provided with oval gyro cone, by gyro cone, cobble disturbance is also loosened, then by rotating vane, cobble is screwed out ground.
The cylinder of gyro cone for having 30 degree ~ 45 degree of cone points, cylindrical diameter is 4 ~ 5cm.
Described drilling rod bar footpath is 80 ~ 200mm, and flight diameter is 600 ~ 1000mm.
Operating principle of the present utility model: after boring reaches land pebble, front end of the present utility model is put in boring, by the torque of machinery, land pebble is unscrewed, in the densification function of being bored by gyro by side soil layer densification, recycling flight takes loosening land pebble out of ground by turning effort, thus hole is formed in land pebble, finally device is taken out in boring.
The utility model drilling tool can repeatedly use, cost-saving, and construction efficiency is high, saves the engineering time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, buckle, 2, drilling rod, 3, helical blade, 4, gyro cone, 5, cone point.
Detailed description of the invention
Shown in Fig. 1, the utility model is made up of buckle 1, drilling rod 2, helical blade 3, gyro cone 4, cone point 5, one end of drilling rod 2 is provided with the buckle 1 for being connected with rig, the other end of drilling rod 2 is cone point 5, drilling rod 2 is evenly equipped with helical blade 3, close on the foremost of cone point 5 two circle rotating vanes edge on weld oval gyro cone 4.
Described gyro cone 4 is for having the cylinder of 30 ~ 45 degree of cone points.Cylindrical diameter is 4 ~ 5cm.
Described drilling rod bar footpath is 80 ~ 200mm, and flight diameter is 600 ~ 1000mm.
