Description

{DRILLING MACHINE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a four-hole perforator, and more particularly, to a four-hole perforator capable of simultaneously perforating four holes by using two perforations.

Generally, perforator is a device that is needed to precede the construction of the civil engineering work for the crushing of the rock for crushing rock, the drilling of the quarry, the reinforcement work of the road slope, and the buried underground measurement. In addition, it is for perforating the hole in the floor of the road and fixing the fixture in order to install the handrail, the street lamp, the soundproof wall,

Another hole has a perforation in which the same hole is to be drilled in a bridge or a bridge pier such as a reinforced concrete or a steel bridge, and an auxiliary device must be installed.

Perforation should depend on the visual sense of the driver's manipulation or the guide attached to the perforator. If there is a change in the angle of the perforated slope, the driver must perforate the slope considering the angle of the slope, and thus it is difficult to maintain a constant perforation operation. In the case of a fixture which has a linear shape like a rail or a soundproof wall, or a combination of several of which is formed by a single purpose, the gap between the one landscape fixture and the next landscape fixture or the direction of the line is fixed. Therefore, constant spacing and position are important. In the case of bridges and bridge piers, there are many narrow parts, and in such a case, there is a problem that a general perforator machine having a length of 1 m or more can not be drilled.

If the perforated ground is a heterogeneous layer, the perforation angle may change if a certain depth is drilled and then changed to hard ground. However, since it is difficult to visually recognize the change of the perforation angle, the perforation angle is drilled at the modified perforation angle and the quality of the perforation is lowered.

Korean Patent Laid-Open Publication No. 10-2008-0006320 discloses a perforator capable of refracting in general and having only a structure for adjusting a perforation angle at various angles, a structure for maintaining a perforation angle constantly, The configuration is not described. Especially, the piers at the lower part of the bridge are reinforced concrete, so reinforced concrete and concrete are combined. It is difficult for the complex strength ground to be punctured uniformly in such a narrow place.

Also, this prior art has had a problem in that it takes too much effort and time to prepare or work for drilling a hole.

Therefore, a technique for solving the above-described problems is required.

Further, the installation which is intended to be attached to the lower part of the specific structure needs to be drilled from the bottom to the bottom. In the case of four pieces of equally spaced four holes in the lower part such as railings, traffic lights and traffic signs, It is possible to install the installation so that the installation is at an angle with respect to the ground, and when the same product forms a linear shape, the same interval must be maintained so that each landscape can be installed in harmony with the whole.

On the other hand, the background art described above is technical information acquired by the inventor for the derivation of the present invention or obtained in the derivation process of the present invention, and can not necessarily be a known technology disclosed to the general public before the application of the present invention .

An embodiment of the present invention has an object to enable four-hole drilling at the same time by using two drill holes.

Further, according to one embodiment of the present invention, since four holes can be formed in a narrow space, an operation time can be minimized and an operation speed can be improved.

Further, one embodiment of the present invention is capable of adjusting the left and right spacing and the height at the same time when perforating the perforated object, so that the object of the present invention is to reduce the construction cost as well as the fast construction.

In addition, one embodiment of the present invention has an object to improve workability and work efficiency by rapidly working four holes having a certain size and spacing in a perforated object.

According to a first aspect of the present invention, there is provided, as a technical means for achieving the above-mentioned technical object, a floor having a square shape with an open upper part and formed with one or more drain holes on a floor surface contacting with the ground, The piezoelectric device according to claim 1, further comprising: a piezoelectric part which is stacked on the upper part and has a rectangular shape which is recessed and opened at an upper part thereof and which has a piezoelectric part for accommodating one or more piezoelectric elements stacked in a plate, And a pressure plate which is formed in a rectangular plate shape and which is formed on the upper portion of the heat generating portion and protrudes upward and is formed at a position corresponding to the piezoelectric element As shown in Fig.

According to any one of the above-mentioned objects of the present invention, it is possible to perform four-hole drilling at the same time using two drill holes.

Further, according to any one of the means for solving the problems of the present invention, since four holes can be formed in a narrow space, the working time can be minimized and the working speed can also be improved.

Further, according to any one of the means for solving the problems of the present invention, it is possible to simultaneously adjust the left and right spacing and the height when perforating the perforated object, thereby reducing the construction cost as well as the construction time.

Further, according to any one of the means for solving the problems of the present invention, it is possible to improve the workability and work efficiency by rapidly working four holes having a predetermined size and spacing in the perforated object.
