Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a half arm unit having an extension connector,

The present invention relates to a chimney unit inserted into a perforation hole to generate cracks in the surrounding ground. More specifically, when a tunnel is excavated, the depth of the perforation hole is increased and the perimeter unit is inserted over a longer area, The present invention relates to a chalcogenide unit equipped with a connector so that it can be carried out.

Generally, in order to excavate a solid ground, a method of generating a crack by forming a perforation hole in a section to be excavated and then inserting a chimney unit into the perforation hole to press the inner surface of the perforation hole through the chimney unit is widely practiced.

The ground motions of the ground through the serpent unit are widely used for drilling or excavating a manual hole on a flat ground, and in particular, for constructing a structure for forming a road or a railway passing through a hillside such as a tunnel.

Conventionally, a blasting method in which a blast hole is formed on a free surface to charge a charge and blasting is performed. A blast hole is formed by forming a perforation hole in a free surface and a perforation hole in a perforation hole to generate a crack in the periphery. And the Vibeilam construction method is being carried out in various ways.

In the case of a location where it is difficult to utilize the construction method where noise and vibration are generated as much as blasting, when the ground is vertically drilled or excavation is performed in a horizontal direction to excavate a tunnel, Is relatively unlikely to occur.

As an excavation of a tunnel, for example, a method of drilling a tunnel by a method of forming a perforation hole on a free surface on which a tunnel is to be excavated and expanding and pressing an inner surface of the perforation hole by inserting a hypolayer unit into the perforation hole is widely practiced, The chimney unit has a disadvantage in that the weight of the chimney unit is increased because the chimney unit is made of a material having sufficient rigidity to generate cracks in the periphery of the perforation hole by utilizing a method of protruding the pressurizing body to the outside of the housing through hydraulic pressure, There is a problem in that the length of the inner space is not made long because the high pressure state due to the hydraulic pressure is repeatedly formed.

Therefore, the depth at which cracks can be formed by inserting the chimney unit into the perforation hole in one step is limited to the length of the chimney unit itself, and the pumping speed that can be pushed when the tunnel is excavated depends on the self length of the chimney unit It was decided.

It is necessary to develop a chimney unit that can generate cracks over a long section by inserting a deep-hole unit at a deeper depth in a single process in excavation of a tunnel that generates cracks around the perforation hole using the chimney unit Has come.
