In the underground construction of various pipelines, most of the installation methods have been carried out by digging out the ground from the ground, connecting the pipelines, and then rebuilding them.

However, when laying the pipeline by the open construction method in the downtown area, the road or ground cannot be used during the construction period. Therefore, it is necessary to open a bypass road at the construction location and to control the traffic. There was a problem that the work is very difficult due to loss and various complaints.

Therefore, the pipeline construction by the non-opening method rather than the existing opening method occupies the market.

Here, if you look briefly at the construction process of the pipeline by the non-settling method, the starting point and the reaching point to bury the pipeline in the underground are drilled in the vertical direction to form the propulsion base and the reaching base, and the direction of excavation of the underground from the propulsion base is determined. Towards the pipeline, the pipeline is formed to form a pipeline, and then the structure inside the pipeline is press-fitted and buried using a propulsion device.

As a prior art disclosed in relation to the pipe propulsion device of the non-adhesive method as described above, Korean Patent Publication No. 231188 (1999.08.27.) Is the first in the main device of the underground buried pipeline, the medium pressure propulsion device Propulsion means provided to be buried in the ground; An actuating means installed in the propulsion means by a fixed bracket to propel the propulsion means when the earth pressure is over a predetermined level in the pipeline; The incision piece is cut in the longitudinal direction so that the lower end has an arc of 30 ° with the origin as the center, and the inner circumferential surface is fixed to the inner circumferential surface of the front and rear of the pipe to which a plurality of brackets are welded at right angles to each other at the same position as the operation means. It is known to include a variable means for varying the inner diameter of the propulsion apparatus of the underground buried pipeline that can reduce the construction cost while reducing the embedding time.

In addition, Korean Patent Publication No. 814711 (February 13, 2008) has a forward base installed on the ground to be installed, and a footboard of a semi-hexahedral cube installed at the bottom in the forward base and having an inner space, and installed on the top of the foothold. A rail, a small high-performance hydraulic motor and a rod rotation speed converter placed on an upper portion of the rail, a hydraulic hose attachment port provided at an upper side of the small high-performance hydraulic motor, and a rod fixing device installed on the other side of the scaffold. In the ultra-small diameter propulsion device, characterized in that configured in, the rod fixing device is inserted into the through hole formed in the center, the rod fixing bearing installed in the through hole, the rod fixing bearing and the upper, left, right side of the hole It is possible to save the cost of propulsion construction by including the adjusting screw for adjusting the direction of engagement in three directions. The micro-caliber propulsion unit is known.

However, in the case of the above-mentioned conventional propulsion device, all of the above-mentioned propulsion devices only propagate in a horizontal straight direction at a certain depth toward the ground. Due to the inevitable delay of work due to the preparation process, the air is long, and there is a problem that there is a limit in the type of work because it can be pushed only in the horizontal direction.

In addition, there is a problem in that there is a problem in that the pipeline can be newly established only by the simple excavation work in the ground, and it is difficult to connect the pipes already installed such as sewer pipes or existing artificial ones.
