Abstract
The present invention is the geological drilling hollow boring bit suitably used in earth's surface broken ground; thin-wall tube-shaped drill main body is made up of plastics; its base opening is smooth cutting portion; ring main body circumference is arranged with water hole; the thread hollow drillstock and thin-wall tube-shaped drill main body same material; internal diameter is equal, and is integral with thin-wall tube-shaped drill main body.This hollow boring bit is integrally adopted made of plastic, appropriate toughness and rigidity are made it have in particular by atactic copolymerized polypropene, its effect is that cutting portion can be crept into earth's surface broken ground, and cutting portion smooth when metal or plastic lined piping and other underground installations are met in drilling process can not be crept into or itself is crushed, the damage of underground utilities, facility can be avoided.This hollow boring bit cost is relatively low, has the outstanding advantages for substantially reducing damage accident rate when being crept into earth's surface broken ground.
Description
Technical field
The invention belongs to drilling equipment, more particularly to a kind of geological drilling sky suitably used in earth's surface broken ground
Heart drill bit.
Background technology
Hollow boring bit is geological drilling common drill bit, it by thin-wall tube-shaped drill main body, be fixed on the blade of main body base opening
The thread hollow drillstock suitable for reading with main body is fixed on is formed, and thin-wall tube-shaped drill main body is provided with water hole, thin-wall tube-shaped drill bit master
The material of body and thread hollow drillstock is metal material, and its blade is usually spaced apart circumferential arrangement using hard alloy, gold
The cutting tooth that the materials such as hard rock are formed, hollow boring bit is connected with core barrel to carry out creeping into coring or drilling to stratum.
Because the cutting tooth hardness of the materials such as hard alloy, diamond composition is high, cutting power is very strong, in drilling process
Tend to occur to be arranged at earth's surface stratum underground utilities, the damage phenomenon of facility, operating personnel have just perceived hollow boring bit and have touched
Have little time to stop when contacting compared with hard objects to bore just generated damage sequence, especially natural gas line, high-tension cable pipeline,
Its damage sequence such as railway communication cable is often very serious.
The content of the invention
The purpose of the present invention in order to during overcoming existing geological drilling metal hollow drill bit easily to the ground on earth's surface stratum
Underground pipelines, facility etc. cause badly damaged technical problem, and disclose a kind of geology suitably used in earth's surface broken ground and bore
Spy hollow boring bit.
The present invention takes following technical scheme to achieve the above object；A kind of geology suitably used in earth's surface broken ground
Probing hollow boring bit, including thin-wall tube-shaped drill main body and thread hollow drillstock, are characterized in, thin-wall tube-shaped drill main body is by moulding
Material is formed, and its base opening is smooth cutting portion, and ring main body circumference is arranged with water hole, the thread hollow drillstock and thin wall cylinder
Shape drill main body same material, internal diameter is equal, and is integral with thin-wall tube-shaped drill main body.
The present invention can also take following technical measures：
The plastics for forming thin-wall tube-shaped drill main body and thread hollow drillstock are atactic copolymerized polypropenes.
The thin-wall tube-shaped drill main body wall thickness is 10-12mm, and its internal diameter is less than metal core bore 2-4mm.
The thread hollow drillstock wall thickness is 5-7mm.
The water hole is shaped as equilateral triangle, and its one side and thin-wall tube-shaped drill main body longitudinal axis are perpendicular, should
The distance of the thin-wall tube-shaped drill main body cutting portion bottom of back gauge is 4.5-5.5cm.
Advantages and advantages of the invention are：This hollow boring bit integrally adopt it is made of plastic, in particular by random
COPP makes it have appropriate toughness and rigidity, and its effect is that cutting portion can be crept into earth's surface broken ground,
And cutting portion smooth when metal or plastic lined piping and other underground installations are met in drilling process will be blocked from creeping into,
Operating personnel stop drilling depth by rig can just avoid underground utilities, sets it has been observed that now taking and proposing the measures such as brill
The damage applied.If operating personnel do not have found that rig stops drilling depth and applies larger machinery driving power in time, power passes
It will be crushed by being handed to this hollow boring bit, and operating personnel will be readily viewed and judge the failure of this hollow boring bit, can also be reached
Avoid underground utilities, the purpose of facility damage.The characteristics of this hollow boring bit is also conductive low, it can avoid or reduce underground
The accident that power network is short-circuited occurs.After the safety depth of no underground utilities and facility is drilled into using this hollow boring bit, you can change
Metal bit continues to drill.This hollow boring bit cost is relatively low, has substantially to reduce and damages thing when being crept into earth's surface broken ground
Therefore the outstanding advantages of incidence.
Brief description of the drawings
Fig. 1 is this hollow boring bit example structure schematic diagram.
Marked in figure：1 thin-wall tube-shaped drill main body, 2 cutting portions, 3 thread hollow drillstocks, 4 water holes.
Embodiment
The present invention is further illustrated with reference to embodiment and its accompanying drawing.
Embodiment as shown in the figure, a kind of geological drilling hollow boring bit suitably used in earth's surface broken ground, its thin-walled
Shell bit main body 1 is made up of atactic copolymerized polypropene (PPR) plastics, and wall thickness 10-12mm, its base opening is smooth cutting portion
2。
Water hole 4 in embodiment is equilateral triangle, and ring main body circumference is arranged with three, length of side 2cm, water hole
4 base and thin-wall tube-shaped drill main body longitudinal axis are perpendicular, the distance h of the thin-wall tube-shaped drill main body cutting portion bottom of the back gauge
For 4.5-5.5cm.
Thread hollow drillstock 3 in figure is identical with the thin-wall tube-shaped material of drill main body 1 to use atactic copolymerized polypropene
(PPR) plastics are formed, wall thickness 5-7mm, and are integral with the injection of thin-wall tube-shaped drill main body 1, and internal diameter is equal, thread hollow
Drillstock 3 and the internal diameter of thin-wall tube-shaped drill main body 1 are less than metal core bore 2-4mm.
Cutting portion 2 should keep smooth, and outer edge should keep smooth in the water hole 4 of triangle, can avoid drilling when pair
Thinner pipeline produces cutting damage.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention.
