Description
Technical field
The present invention relates to a kind of Pipeline Crossing by Horizontal Directional Drilling construction technologies, specifically, be related to production that a kind of time is towed the head and
Application method.
Background technique
Commonly used with Pipeline Crossing by Horizontal Directional Drilling construction technology, pipeline returning is crucial work during crossing construction
One of sequence, pipeline returning it is smooth whether, affect construction quality, the even success or failure of engineering.
When the river for passing through some large sizes is constructed, since traverse distance is long, passes through that caliber is big, geological stratification is hard, cause
Return that frictional resistance between hauling pipe road and pilot hole is big, and corresponding pipeline back drag force is also big, return insulating layer during dragging be damaged it is several
Rate is also big, so frictional resistance caused by reducing because of various aspects factor, is the key that pipeline returning, and returns the production towed the head and makes
With one of the factor for being reducing friction resistance, thus, how to make it is reasonable return tow the head it is most important.
Summary of the invention
Technical problem solved by the invention is to provide the production and application method that a kind of time is towed the head, and efficiently solves
Over long distances, big-diameter pipeline passes through back the problem dragged in hard geological stratification.
Technical solution is as follows:
A kind of time production method to tow the head, comprising:
Ring protection is covered and is connect at the flaring of transiting arc plate；
Make circular arc plate, and by the flaring of circular arc plate be connected at the closing in of transiting arc plate；
Ear is drawn in connection at the closing in of circular arc plate, draws ear to be provided with connecting hole, connection hole is equipped with U-shaped ring；
Ring protection set, transiting arc plate, circular arc plate inner wall on connection reinforcement gusset, stiffener plate top connection
On drawing ear.
Further, transiting arc plate is taper type cyclic structure, the horizontal sextant angle of the outer wall of transiting arc plate is 0-30 °.
Further, circular arc plate will be spliced by multiple trapezoidal plates after sidewall weld.
Further, returning hauling pipe road cut-space using one section goes out trapezoid slit, material in trapezoid slit is removed, is then adopted
With after annular-heating by trapezoid slit between trapezoidal plate bending, will at gap weld after formed circular arc plate.
Further, circular arc plate is connected at the trapezoid-shaped openings for drawing ear, plug is welded at the closing in of circular arc plate.
Further, the top of stiffener plate is connected on the inner wall for the trapezoid-shaped openings for drawing ear, the rear end of stiffener plate is located at
Ring protection set inside, 2 pieces of stiffener plates are arranged in cruciform shape.
It is polished using sanding machine weld further, molding time will be made and towed the head, the transition that guarantees back to tow the head is flat
It is sliding, no recess, corrugationless, without welding slag.
A kind of time application method to tow the head, comprising:
The insulating layer of pipe end is dragged to remove by returning, annular protective case is inserted into the end for going back to hauling pipe road, then will return hauling pipe
Road welds together with ring protection set；
The U-shaped ring for returning connection hole installation on the drawing ear to tow the head is connect with the universal joint of reamer rear end；
Drilling rod pulls reamer to advance in turn hole, and the water hole of reamer sprays mud lubrication, return the circular arc plate to tow the head,
Transiting arc plate successively opens mud, and ring protection set drives back hauling pipe road to advance, and drills out turn hole until going back to hauling pipe road.
It is preferred: ring protection being covered by the gap between insulating layer using polyurethane heat insulation material and is filled.
Preferred: confirmation is clean in hole after the completion of pre- reaming procedure, starts go back to hauling pipe road；Ring protection set encases back
The end in hauling pipe road can prevent insulating layer from damaging during advance.
The technology of the present invention effect includes:
Hauling pipe road is gone back to present invention efficiently solves long range, Large Diameter Pipeline, and the problem dragged is passed through back in hard geological stratification.Energy
Enough reduces go back to hauling pipe road time drags resistance, improve back the success rate for dragging pipeline returning, and effective protection insulating layer ensure that conscientiously
Construction quality, construction benefit improve significant.
Using the present invention, when pipeline returning, insulating layer is not easily susceptible to destroy, and guarantees that pipeline smoothly returns and drags.Avoid pipeline
End erosion resistant coating is destroyed because frictional resistance acts on, and uses polyurethane heat insulation material by ring protection set and pipe insulation
It is filled between layer, because of squeezing action anticorrosion insulating layer is destroyed when effectively preventing pipeline returning.
Returning in pipeline returning drags resistance small, draws the steel plate corner of ear at arc-shaped, reduces and draws nose and guiding hole wall
Frictional resistance because steel plate thickness be 30mm, have very high intensity, it is sufficient to carry back the pulling force and stress generated when dragging.
Circular arc plate and transiting arc plate stress surface are smooth, at streamlined, reduce the flow resistance of mud and between guiding hole wall
Frictional resistance.
