Background technique
Drilling project is during construction drill, when encountering the 4th system, incompetent bed or rock engineering features as poor geologic condition
Phenomena such as location needs to install additional seamless steel pipe as orifice tube, just can guarantee the smooth construction of drilling, is not so easy to appear collapse hole,
Cause to drill useless hole or drilling equipment is nuzzled in drilling, to cause the loss of property and equipment；In the construction process, hole
Mouth pipe is all often that disposably, cannot extract recycling, and such case has resulted in wasting, one in the market
The orifice tube price of 108mm bore is 80 yuan/m.
When the thickness for encountering some the 4th systems, incompetent bed or rock engineering features as poor geologic condition stratum is deeper, construction
Required inbuilt orifice tube is with regard to long, and (length of general single factory orifice tube is when the biggish orifice tube of built-in length
9m), it needs to weld together more orifice tubes, is just able to satisfy the length requirement of construction, in this case, inbuilt orifice tube
It is disposable, and it is easy to appear fractures during drilling operation for orifice tube welding position, cause orifice tube to waste, very
To needing to do over again, to bring economic loss to construction party.
Utility model content
The purpose of this utility model is to provide the centres of a kind of drill hole pipe of recoverable and connection orifice tube
Connector, to solve the problems, such as that it is low with structural strength that existing orifice tube can not be reused.
To achieve the above object, the utility model provides a kind of drill hole pipe of recoverable, the recyclable benefit
Drill hole pipe includes aperture tube body, the aperture tube body in tubular construction, aperture tube body both ends it is interior
Edge is respectively arranged with interior screw thread.
Preferably, the aperture tube body is seamless steel pipe.
Preferably, the wall thickness of the aperture tube body is 7-8mm.
Preferably, protective paint has been respectively coated in the inner surface and the outer surface of the aperture tube body.
Preferably, the depth of the interior screw thread is uniform from deep to shallow during the port of joint body thereto portion's extension
Gradual change.
Preferably, the depth of the interior screw thread is 3-4mm.
Corresponding, the utility model also provides a kind of transition joint for connecting orifice tube, in the connection orifice tube
Between connector include joint body, in tubular construction, the outer edge at the joint body both ends is respectively arranged with the joint body
Male thread, from the port of joint body, portion extends uniform gradual change from deep to shallow in the process to the depth of the male thread thereto.
Preferably, the depth of the male thread is 3-4mm.
The utility model has the advantages that the drill hole pipe of the recoverable of the utility model is increasing wall thickness
Meanwhile interior screw thread is respectively set by the inward flange at aperture tube body both ends, to realize detachably connecting between orifice tube
It connects, to meet biggish 4th system of thickness, incompetent bed or the construction requirement on rock engineering features as poor geologic condition stratum.Using finishing
Afterwards, using the connector screwed connection of the interior screw thread of first order orifice tube and probing lifting means, by drilling lifting means for hole
Mouth pipe is promoted to ground, then is dismantled one by one, to realize the recycling of orifice tube, while reducing construction cost, also
Reduce hole risk of giving up present in construction.
Detailed description of the invention
Fig. 1 is the side elevational cross-section structural schematic diagram of the drill hole pipe of the utility model recoverable.
Fig. 2 is the side elevational cross-section structural schematic diagram for the transition joint that the utility model connects orifice tube.
Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
As shown in Figure 1, the drill hole pipe of recoverable includes aperture tube body 1, aperture tube body 1 is tied in a tubular form
Structure, aperture tube body 1 are seamless steel pipe, it is ensured that aperture tube body 1 has higher structural strength, prevents to deform or break
It splits.The wall thickness of traditional orifice tube is 3-4mm, and 1 wall thickness of aperture tube body of the utility model is thickeied, and reaches its wall thickness
To 7-8mm, the structural strength of aperture tube body 1 is further increased.Further, the inner surface and the outer surface of aperture tube body 1
Protective paint is respectively coated, protective paint can effectively prevent corrosion of the underground water to aperture tube body 1, extend aperture tube body 1
Service life, to further decrease construction cost.The inward flange at 1 both ends of aperture tube body is respectively arranged with interior screw thread 11, interior
The depth of screw thread 11 is 3-4mm, and from the port of joint body, portion extends in the process from deep to shallow the depth of interior screw thread 11 thereto
Uniform gradual change, it is such to design when can guarantee aperture tube body 1 with transition joint screwed connection, can more on it is tighter, to prevent
The generation of 1 case accident of aperture tube body occurs.
As shown in Fig. 2, the utility model also provides a kind of transition joint for connecting orifice tube, connect in orifice tube indirectly
Head includes joint body 2, and in tubular construction, the outer edge at 2 both ends of joint body is respectively arranged with male thread 21 to joint body 2,
From the port of joint body 2, portion extends uniform gradual change from deep to shallow in the process to the depth of male thread 21 thereto.Male thread 21
The button-type of button-type and interior screw thread 11 matches, and the depth of male thread 21 is 3-4mm.Further, joint body 2 is similarly seamless
Steel pipe, to ensure it with enough structural strengths.
Application method: when burying orifice tube during drilling operation, afterbody orifice tube, afterbody aperture are first descended
One end of pipe is equipped with interior screw thread 11, and the other end can not set interior screw thread 11, upward by one end equipped with interior screw thread 11, complete last under
When level-one orifice tube, one end of afterbody orifice tube is fixed with pipe wrench, in indirectly by one end of afterbody orifice tube
One end connection of head, fixes transition joint with pipe wrench after connection, connects next stage aperture in the other end of transition joint
Pipe continues embedded next stage orifice tube, reconnects next transition joint after connection, and so on, until first order hole
Mouthful pipe bury, then starts drilling operation, after drilling operation, screw thread 11 in first order orifice tube is set with promotion is drilled
Orifice tube is promoted to ground by probing lifting means, then is dismantled one by one by standby connector screwed connection, to realize hole
The recycling of mouth pipe while reducing construction cost, also reduces hole risk of giving up present in construction.
Although being above described in detail with generality explanation and specific embodiment to the utility model,
On the basis of the utility model, it can be modified or is improved, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
