It relates to an economical method for controlling an unexcavated excavation system of an underground pipeline.

In general, as described as background art in Registration No. 10-1309774, in living infrastructures such as houses and roads, water and sewage pipes for drinking water supply and sewage treatment or pipes for the role of underground lines for electric power and communication cables are laid underground. plumbing work is performed.

And, in order to solve various problems of the open-cut piping construction, in recent years, the horizontal directional drilling method (HDD), which allows the construction of the above-mentioned underground line without opening the ground surface, is mainly being performed. am.

This steerable horizontal drilling method uses the existing open trench method for ground subsidence due to backfilling and backfilling as well as traffic congestion during ground surface excavation, as well as clogging construction and tracks in rivers, etc. right

It has the advantage of being able to overcome meeting problems at once.

The steerable horizontal drilling method is a method of starting underground using a small-diameter drill head and jetting pressure so as not to cause destruction or deformation of the upper structure during pipe line construction and underground installation construction. It has the advantage of being able to work directly from the ground at a desired angle and depth in a 360-degree direction, avoiding obstacles identified in advance, even in the construction of a small city, especially in complex urban construction. Bypassing water is possible and by adjusting the concentration by rotting a small amount of bentonite and water, there is no risk of subsidence.

As the equipment required in the steering-type horizontal drilling method, it consists of an engine, an excavation track, and a mounting device for a driving rod, and the driving rod is connected to a main device for providing rotational force and propulsion force, and the driving rod At the tip, a drill header and a reamer used during excavation and digging are selectively connected to each other.

The process of such a steering-type horizontal drilling method is briefly described as follows.

First, after the drill header is rotated forward to drill the conduit hole, the drill header is separated from the drive rod drawn out in the opposite direction of the conduit hole, and a reamer is connected instead, and then the reamer having rotational force is pulled By pulling and excavating the small-diameter pipe hole again, it is made into an expansion hole.

Here, during excavation and digging using the drill header and reamer, diluent mixed with bentonite in an appropriate ratio in water to increase the excavation efficiency and prevent the pore wall of the pipe hole from subsidence (泥水掖, "hereinafter Bentonite diluent) is injected at high pressure in the direction of excavation forward.

Finally, during the expansion of the pipe hole, the pipe body for underground burial is hung on the reamer to immediately bury it, or it can be buried by inserting it into the expansion hole separately later.

The steering-type horizontal drilling method for performing the work through the above steps has a problem in that the precision of the work is deteriorated because the driving rod is broken and cut due to the pressure in the ground during the drilling.

That is, when excessive pressure is generated during the reaming by the reamer, the work cannot be performed properly as the driving rod pulling the reamer is broken and lost, and there is a problem that the reconstruction must be performed in a different route.

And in order to solve this problem, in claim 1 of Registration No. 10-1309774, a starting port and an arrival port, which are working spaces, are formed at the starting and arrival positions for excavation of the underground pipeline, and a drill head is attached to the front end of the starting port.

The present invention further combines the drilling bit with the drilling bit at the arrival point after non-excavating the excavation section with the diamond drilling bit, connecting the pe pipe to the rear of the drilling bit, and pulling the drilling bit to the first excavation start position to drill will be.

In addition, the non-cutting excavation method is to replace and install the diamond drilling bit with a drilling bit at the destination after non-cutting the excavation section with a diamond drilling bit, connect the pe pipe to the rear of the drilling bit, and then pull it to the initial position.

The non-cutting excavation method is to excavate the excavation section using a bit combined with a diamond drilling bit and a drilling bit.

The non-excavation system of the underground pipeline of the present invention is to construct an underground pipeline for water supply in the ground with the tip and middle parts of the bit, and the coupling part of the rear.

The perforated bit can be configured to be used as an expansion bit, and the tip of the bit is formed with a rounded tip to prevent soil, etc. from being buried during rotation. And a cutting edge having a cutting function is coupled to the tip of the front end of the body. In particular, the three cutting edges are formed, and are formed radially to equalize the cutting force.

A cutting blade having a cutting function is coupled to the outer periphery of the front end of the body. And the front end of the body is formed in a cone shape to become narrower toward the front end, and the middle portion is formed to become wider toward the rear.

Protrusions are formed on the outer periphery of the middle part to expand the perforated hole.

In particular, a hole-formed spray protrusion is formed on the rear outer periphery of the middle part, and when the bit is reversed, the water introduced from the rear is discharged.

A check valve is installed in the coupling hole to prevent backflow of muddy water.

And the present invention constructs some rock sections in a non-interleaving manner using the bit of the present invention, and during shooting and drilling construction, fills the excavation hole with bentonite, etc. , and also prevents the surrounding environment from being polluted by foreign substances discharged after construction.

The tip is rounded like a cow's nose.

The construction method of the present invention has three methods as follows.

The first method is to further combine the drilling bit with the drilling bit at the arrival point after non-excavating the excavation section with a diamond drilling bit, connect the pe pipe to the rear of the drilling bit, and pull the drilling bit to the first excavation start position to drill will do

The second method is to replace the drill bit with a drill bit at the destination after non-excavation with a diamond drill bit, and then pull it to the initial position after connecting the pe pipe.

The third method is to combine the drilling bit and the drilling bit together for construction, and the rear drilling bit drills the hole drilled by the drilling bit.

And the general drill bit has a small number of blades and is not sharp, but the

The bit has many blades, is twisted in several directions, and is easy to propel rocks and other obstacles.

According to the first construction method, after excavation, the diamond bit drilling bit is replaced with the drilling bit, and the drilling is carried out.

In the present invention, the method of connecting the pipe to the bit in which the drill bit or the drill bit or the diamond drill bit and the drill bit is coupled together is connected to each other by the tow hook module.

Usually, one traction ring is connected in the prior art, but the present invention is constructed by connecting two PE pipes at a time by a traction ring module composed of a traction ring and a pair of connecting rings. Shortly, by connecting the diamond drilling bit to the tow hook module, the working time is cut in half, and in particular, the non-excavation of the pipe becomes quick and easy by using the diamond drilling bit in the rocky area.

And, in general, the conventional tow hook, which is a metal ring attached to one end of the cylindrical body, is heavy and has a complicated internal socket, so it is difficult to connect a pipe in the field and the efficiency is low. Although a ring is installed, it plays a role of tightening after inserting the pipe, and the rubber ring may come off while tightening, and in this case, there is a disadvantage that the pipe is separated during operation.

In contrast, the traction ring module of the present invention can be customized for each pipe size by a pair of connecting rings, and is made of a plastic material.

The product itself is light, easy to install, and has the advantage of no pipe separation.

It is symmetrically coupled to the tow ring with a disc in between.

A double linkage, that is, a twin linkage, is a traction ring coupled to the upper surface of the disk and two hooks coupled side by side on the lower surface of the disk.

The traction ring into which the existing pipe and pe pipe are inserted is made of iron, but the connecting ring of the present invention is made of plastic, especially pe material.

The advantage is that the structure itself is simple, and it is light and easy to carry.

In addition, since several connecting rings are manufactured for each size of the pe pipe, it is easy to work by connecting the connecting rings of the tow hook module suitable for the size in the field. Existing commercial products have a rubber packing inside the tow ring, so when it is removed, the pe pipe also falls out. Therefore, it is tightened by the elastic force, so there is no risk of deviated from the pipeline during operation.

The traction hook module is manufactured inexpensively by injection. In particular, when the tube diameter is large, the traction ring and the disc can be manufactured by cutting iron and integrally formed with the connecting ring by insert injection. Therefore, connecting rings of various sizes can be mounted on a tow hook of a certain size. If necessary, the size of the two connecting rings can be different for convenient use.

When describing the pipe housing connection configuration of the present invention, the pipe to which the diamond drilling bit of the present invention is connected is inserted into the housing and the pipe is inserted into the housing.

The present invention is usually excavated in one direction over the entire excavation section and drilled to the other side. However, if the excavation section is long, the technique of excavating only some sections and excavating from the other side may be used. Therefore, the operator can meet accurately without error in using the monitor.

To this end, a bit body controller housing is installed inside the rear pipe connected to the underground excavation bit, and a communication module is mounted inside the bit body controller housing to communicate wirelessly with the ground controller. Or take it out through an excavation hole by wire and use it by connecting it to a controller on the ground. A GPS module is installed in the bit body controller housing to accurately determine the location. 8 is a picture of the controller of the present invention, FIG. 9 is a picture of the state in which the depth of the bit is displayed on the display of the present invention, FIG. 10 is a picture of the state in which the direction of the bit is displayed on the display of the controller of the present invention, FIG. This is a picture of the body controller.

The terrestrial controller that wirelessly communicates with the bit body controller of the drill bit consists of a storage unit for storing data, an input unit, an output unit, a transmitter, a receiver, and a control unit. The control unit allows the received data to be displayed on a display (monitor) through the output unit to be confirmed. The input unit uses a touch panel and a touch screen, and in this case, the output unit can be used together. The control signal input through the input unit is transmitted to the bit body controller through the transmitting unit to control the excavation bit. And the controller is equipped with a display to check the position of the bit inside the excavation hole.

The drilling holes excavated from opposite sides can take the horizontal direction and are designed and controlled in the height direction as well. And it is possible to simultaneously control the deviation in the horizontal direction and the deviation in the height direction depending on the bedrock.

The controller of the present invention installed on the ground is in the form of a control panel, which is a control panel, and it can be seen that when the directions displayed on the underground excavation bit body and the ground controller display on the monitor coincide, the same direction becomes the same. As an example, as shown in the drawing, the 9:30 direction display is equally displayed. Therefore, it can be seen that the excavation bit is excavated precisely in the direction indicated by the controller.

As described above, the current direction of the underground excavation bit is displayed on the display of the ground controller, and the excavation depth in the ground, the pipe position, the water spray temperature, and the like are displayed.

The details of the monitor display of the underground main body bit body controller monitor and the ground controller equipped with the pipeline detection function are described in detail with reference to the drawings as follows.

The angle (height) of the bit body controller housing, battery, housing temperature, pressure, etc. are displayed on the bit body controller monitor, and the direction, angle, frequency, temperature, etc. are displayed on the connected controller monitor on the ground.

After inserting the pipe with the housing into the basement, the ground controller monitor first searches for the location of the pipeline with the frequency sent from the underground bit body controller. And the operator who is operating the underground excavation bit body checks the direction.

When the pipe direction is the same as the direction transmitted from the underground excavation bit body matches the detected pipe position displayed on the ground controller's monitor, the same direction is displayed.

In addition, the temperature is controlled by the temperature of the housing pipe of the bit body controller connected to the excavation bit. If the housing temperature is over 40 degrees during the operation of the excavator, damage to the excavation bit may occur. In order to limit the temperature to less than 40 degrees, The ground controller controls the excavation speed and water injection amount.

According to the drawing, it can be seen that the direction indicator on the bit body controller of the excavation bit also indicates the direction in time at 9:30, 10 o’clock, etc., and check whether the direction of the excavation bit is going well as set in the connected controller monitor on the ground. And if the direction goes in the direction indicated, it can be seen that the same value appears (Example: 9:30 minutes photo)
