Description

High pressure percussion TBM tunnel excavation device {TBM TUNNEL EXCAVATION DEVICE}

The present invention relates to a high-hydraulic percussion TBM tunnel excavation device, and more specifically, to a high-pressure percussion TBM tunnel excavation device that can perform excavation work using water pressure.

In general, with technological advancement, since the 1980s, technologically advanced countries such as Germany, Japan, and the United States have been developing mechanical tunnel excavation methods to increase tunnel excavation efficiency, promote safe construction, and shorten construction periods.

The conventional excavation method currently developed and used is the TBM (Tunnel Boring Matchine) tunnel excavation method, which opens or blocks the excavation equipment depending on the ground condition (soil layer, rock layer, fractured zone, etc.). In the TBM tunnel excavation method, a number of bits are attached to the front to crush the rock, and the rock is excavated as the TBM equipment is advanced into the rock by a jack. The excavated rock is mixed with mud and discharged to the ground by a high-pressure pump outside the tunnel, or if there is little groundwater, the excavated crushed rock is dropped to the bottom of the TBM chamber and transported by conveyor belt to the mine car, which is the excavated debris transport equipment within the tunnel. The transported rock is transported by mine car to the tunnel work area, lifted to the ground along with the mine car using a crane installed on the ground, and then unloaded at the dumping site. The unloaded rock is brought to a sand pit with a moisture content of 60 to 80%. Dispose of sand.

This conventional TBM tunnel excavation method is safer compared to conventional methods such as manual or explosive blasting methods, and the excavation efficiency has been greatly improved. However, if the rock condition of the excavation ground is formed of joints, fracture zones, quartz, and heterogeneous layers, the bit may be damaged. There is a problem that frequent maintenance is required due to damage or damage, and due to increased parts replacement time, work cannot be performed during the consumable replacement period, which reduces excavation efficiency.

Accordingly, the control unit 700 may include a device such as a computer, a microprocessor, an integrated circuit, or a processing device including a programmable logic device.

Hereinafter, the operation of the high-hydraulic hitting TBM tunnel excavation device 1 according to an embodiment of the present invention will be described.

Figure 5 is a cross-sectional view schematically showing the operating state of the high-hydraulic hitting TBM tunnel excavation device according to an embodiment of the present invention, and Figure 6 is a front view schematically showing the operating state of the excavation unit according to an embodiment of the present invention. Figure 7 is a cross-sectional view schematically showing the operating state of the excavation member and the vibration generator according to an embodiment of the present invention.

Referring to FIGS. 5 to 7 , the operator drives the first driving unit 200 with the main body 100 arranged so that the front of the excavating unit 300 faces the excavating surface 2.

As the first driving unit 200 is driven, the main body 100 advances toward the drilling surface 2 and brings the digging unit 300 into contact with the drilling surface 2. The first driving unit 200 continues to advance the main body 100 during the excavation operation so as to maintain contact with the excavation surface 2 as the excavation unit 300 excavates the excavation surface 2.

Thereafter, the vibration generating unit 500 generates vibration by high-pressure water and moves the excavating unit 300 back and forth in the forward and backward directions to excavate the excavation surface 2.

More specifically, the supply unit 510 receives high-pressure water through the supply pipe 511, maintains the pressure of the high-pressure water at a predetermined value through the pressure control unit 512, and maintains the pressure of the high-pressure water at a predetermined value through the branch pipe 513. High-pressure water is supplied to the control unit 520.

Thereafter, the control unit 520 repeatedly opens and closes the flow of high-pressure water so that the high-pressure water is sprayed toward the front inner surface of the excavation member 320 at a set frequency.

The high-pressure water sprayed from the control unit 520 slides and moves the excavation member 320 forward as it hits the front inner surface of the excavation member 320, and accordingly, the front surface of the excavation member 320 is the excavation surface ( 2) will be hit. Afterwards, the excavation member 320 slides backwards due to the repulsion force resulting from hitting the excavation surface 2 and the high-pressure water that is reflected from the front inner surface of the excavation member 320 and strikes the rear surface of the excavation member 320. do.

This process is repeated as the control unit 520 repeatedly sprays high-pressure water at a set frequency. Accordingly, the excavation member 320 can crush the excavation surface 2 by repeatedly hitting the excavation surface 2.

In this case, the vibration isolation unit 540 installed between the excavation member 320 and the excavation body 310 is elastically deformed as the excavation member 320 reciprocates, and the excavation member 320 excavates by the amount of elastic deformation. Vibration applied to the sub-body 310 is attenuated.

Meanwhile, a portion of the high-pressure water sprayed onto the front inner surface of the excavation member 320 is sprayed onto the excavation surface 2 through the discharge portion 530, and the excavation surface 2 is further crushed by the sprayed pressure. .

Simultaneously with the operation of the vibration generating unit 500 described above, the second driving unit 400 generates a rotational driving force to rotate the excavator body 310 clockwise or counterclockwise. In conjunction with this, the first excavation member 321, the second excavation member 322, and the third excavation member 323 of the excavation member 320 are also rotated, and the positions at which they hit the excavation surface 2 are continuously changed. Accordingly, the excavation member 320 can perform excavation work over the entire area of the excavation surface 2, as shown in FIG. 6.

In addition, throughout this operation process, the sensor unit 610 of the measuring unit 600 measures the pressure of the high-pressure water, and the exploration unit 620 measures the shape and material of the drilling surface 2 and provides the measured data. It is transmitted to the control unit 700. Afterwards, the control unit 700 compares the received high-pressure water and data on the excavation surface 2 with the previously input data, and based on the compared analysis results, the first driving unit 200, the second driving unit 300, and Controls whether or not the vibration generator 500 operates and its operating intensity.

According to the above-described information, the high-pressure striking TBM tunnel excavation device according to the present invention can greatly improve the crushing ability by replacing the crushing ability of the excavation surface with the impact and hitting method.

In addition, the high-hydraulic blowing TBM tunnel excavation device according to the present invention can perform uniform excavation work over the entire excavation surface as the excavation part reciprocates and rotates simultaneously.

In addition, the high-pressure striking TBM tunnel excavation device according to the present invention reduces the contact time with the excavation surface compared to the friction excavation method, thereby reducing costs and manpower due to frequent replacement of equipment due to friction.

In addition, the high-pressure hitting TBM tunnel excavation device according to the present invention can absorb vibration of the excavation section by means of a vibration isolation unit, thereby preventing damage to the equipment due to repetitive vibration.

In addition, the high-pressure blowing TBM tunnel excavation device according to the present invention can measure high-pressure water and information on the excavation surface in real time, thereby performing more accurate work and preventing safety accidents due to incorrect operation.

The present invention has been described with reference to an embodiment shown in the drawings, but this is merely illustrative, and various modifications and other equivalent embodiments can be made by those skilled in the art. You will understand.
