In addition, the caterpillar 20 is installed on the left and right of the dredger 10 is landed on the left and right sides of the circular pipe (2) and moved, the upper and lower shaft 23 of the caterpillar wheel on which the caterpillar 20 is mounted will be described later The bracket 25 for the support arm 13 is installed and the frame 26 connecting the front and rear brackets 25 is supported by the piston rod 15b of the plurality of cylinders 15a installed in the dredger 10 so as to support the caterpillar ( 20 is configured to be adjustable in the left and right width direction of the circular pipe, the vertical support arm 13, the roller 14 is installed at the front and rear of the boss of the caterpillar wheel 21 and the upper and lower centers of the dredger 10. ) Is installed.

The support arm 13 is composed of a cylinder 13a and a piston rod 13b thereof. It is preferable that a spherical roller freely rotated 360 degrees is provided as the roller 14 at the front end of each piston rod 13b. .

The caterpillar 20 is driven by the front or rear of the caterpillar fan 21 is rotated by a drive means including a motor (not shown), the motor is installed on the left and right or one motor and belt or Power transmission means such as a chain may be provided (not shown).

In addition, the perspective camera 61 is protrudingly mounted in front of the boss of the excavation / introduction means 30. When the perspective camera is photographed, the operation of the dredger is controlled to stop.

On the other hand, as shown in Figure 6, the inside of the conveying pipe 53, the air compressor (when generating the vortex by the compressed air) or high pressure installed on the ground to generate the vortex to prevent the sediment of deposit in the tube It is preferable that a high pressure hose 55 is connected to the water pump and provided with the injection nozzles 55a at predetermined intervals.

The injection nozzle 55a may be formed only in a predetermined region in which the transfer pipe 53 is horizontally disposed.

Further, in the boring and dredging method of the circular pipe according to the present invention, the dredging device 1 is introduced into the circular pipe through the manhole, and the sediment dewatering device 5 is installed on the ground, and the boring and dredging device 1 is provided. Block the back of the manhole section into which water is injected (low point where water flows), and then proceed with work filled with water, and the water discharged through the boring and dredging device is connected to the ground sediment dewatering device and the recovery pipe (7). Through the transfer back to the upper manhole (high point where the water flows) is made continuous circulation use (see Figure 7).

An operation state according to the present invention having such a configuration will be described with reference to FIG. 7.

First, since the inflow of sewage is not much, the barrier film 6 is installed to prevent the water from escaping from the rear of the manhole section of the sewage circular pipe 2 to which sediments are fixed.

And the radius is adjusted and set using the cylinder 36a and the piston 36b of the said excavation / introduction means 30 in accordance with the radius of the circular pipe 2 before the circular pipe of the apparatus.

Afterwards, the sediment is called by filling the water to facilitate the dredging work in the section of the circular pipe (2) blocked the rear. In this case, when there is enough water in the circular pipe, the water filling process is omitted, as well as the need for installing a barrier film.

In the apparatus 1 according to the present invention entering the circular pipe 2 of the sewage pipe or water pipe, the caterpillar 20 on both the left and right sides is moved in close contact with the circular pipe. At this time, by advancing and retracting the cylinder piston rod 15b supporting the frame 26 according to the radial width of the circular pipe, it is closely supported.

And the vertical height of the upper and lower support arms 13 is adjusted to firmly support the upper and lower portions of the circular pipe by adjusting the piston rod 13b of each cylinder 13a.

In this way, the excavation / introduction means 30 is driven with appropriate clearance in the state where the top, bottom, left and right of the dredger 10 is firmly supported in the circular pipe.

When the excavation / introduction means 30 is rotated, sediments, garbage, vinyl, and the like accumulated on the bottom of the circular pipe flow into the inlet 11 of the dredger by the impeller wing 31, and at the front of the impeller wing The cutting blade 32a is primarily used to cut vinyl or tree branches, and the cutting blade 32b attached to the rear of the blade is crushed on the cutter net 12 to pass through the eyes of the cutter net 12. Only crushed enough to be introduced into the dredger. And deposits (solids) that do not pass through the cutter network 12 falls to the bottom side of the circular pipe (2) through the upper chamfer 16 of the inlet (11). The solid deposit thus separated is collected in a subsequent process which is carried out after the operation by the apparatus 1 of the present invention.

In addition, by the plurality of excavation bites 37 mounted on the circumferential front and the outer circumferential surface of the outer wheel 35 of the excavation and introduction means 30, the recessed portion of the circular pipe or the branch pipe protruding into the circular pipe, etc. The cut is excavated to restore the original cross-sectional area with a circular tube. And the damage occurs, such as cracks through the fluoroscopy camera 61 to record the repair work of the circular pipe in the subsequent process.

The sediment introduced into the inlet of the dredger 10 is discharged and treated together with water to the sludge dewatering device 5 installed on the ground by the transfer pump 51 by the transfer pump 51 and the water separated from the sediment is recovered. It is conveyed to the upper part of the manhole (to a high point) through the tube 7 and continuously circulated.

In the dredged conveying pipe 53, if the water flow rate is slow or the amount of water is small, the dredged water sinks. To prevent this, the nozzle 55a installed at a predetermined interval in the high pressure hose 55 inside the dredged conveying pipe. High pressure water (or compressed air) is injected through the vortex to prevent the sediment from sinking in the transfer pipe, thereby smoothly transporting.

In addition, when the caterpillar moves, a roller 14 rotatable 360 degrees is installed at the front end of the support arm 13 to smoothly move and maintain strong support.

As described above, the present invention can actively cope with the change in diameter of the circular pipe (for example, the depression) by adjusting the width of the left and right caterpillars and the length of the support arms according to the size of the circular pipe of the sewage pipe, and the dredger 10. While the up, down, left, and right sides of the support are firmly supported, the excavation and introduction means 30 is driven, so that the apparatus is operated stably.

In the above, preferred embodiments of the present invention have been described with reference to the accompanying drawings. Here, the terms or words used in the present specification and claims should not be construed as being limited to the common or dictionary meanings, but should be interpreted as meanings and concepts corresponding to the technical spirit of the present invention.
