Transfer gear, connecting pipe, back of pipeline is pulled at rig position, and complete pipeline lays work.
Advantages of the present invention
The invention provides a kind of ground consisting of hard rock for carrying out reaming in ground consisting of hard rock using positive motive force reaming construction technology
Positive motive force Counterboring apparatus, instead of traditional Counterboring apparatus and technique.Can realize that motor is folded with rig rotating speed, the effective of moment of torsion
Plus, it is to avoid drilling rod because caused by frictional resistance along journey loss of machine of torque so that in solving hard rock, the construction of long range horizontal directional drill
The reaming efficiency that causes due to being short of power is low, the disconnected de-, reaming bit of drilling rod falls the problems such as taking turns, and to improve reaming efficiency, reduces
Drill rod abrasion.Lithosphere reaming efficiency can be made to improve 3-5 times simultaneously, effective reduces cost shortens the construction period.

Specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in figure 1, the positive motive force Counterboring apparatus of ground consisting of hard rock of the invention include what is be sequentially connected along reaming direction
Horizontal directional drilling machine 21, drilling rod 22, helicoid hydraulic motor 24 and drill bit 25, wherein reaming direction (drill bit advancing direction) are fixed away from level
To rig.
The method for carrying out reaming by the positive motive force Counterboring apparatus of above-mentioned ground consisting of hard rock comprises the following steps：
The first step：It is oriented to construction
Guide instrument azimuth determination is carried out on ground, and instrument is arranged on inside non magnetic drill collar, often creep into a brill
Bar carries out data acquisition, and drill bit is grasped in real time in the position of underground, when disturbing larger, is carried out in surface deployment terrestrial beacon systems
Correction, until drilling is to unearthed point, is oriented to technique as shown in Figure 5；
Second step：Reaming is constructed
Pilot hole (for example using 216mm drill bits) prolongs drilling rod setting of casing to lithosphere after drilling through.Casing diameter is than last
Level counter bore diameter is big by 10%, extracts whole drilling rods out；
311mm or 393mm drill bits are installed according to formation hardness lithology, reaming is just pushed away.Drilling depth is observed in reaming procedure
Speed, propelling pressure and mud displacement pressure；
First order reaming is completed to install next stage reaming bit, and next stage reamer is selected according to upper level reaming data
It is differential.It is general differential no more than 200mm in line with the principle of small differential fast footage.
According to the increase in reaming aperture, the diameter of helicoid hydraulic motor also accordingly increases, general to match somebody with somebody with being combined into 172mm helicoid hydraulic motors
241mm and 311mm rock drill bits, 203mm helicoid hydraulic motors match somebody with somebody 393mm and 406mm rock drill bits, and 244mm helicoid hydraulic motors are matched somebody with somebody
445mm, 660mm and above rock drill bit.
3rd step：Pipeline returning
After the completion of reaming after unearthed point unloads helicoid hydraulic motor and drill bit, common reamer, transfer gear, connecting tube are installed
