In the present invention, a drainage hole drilling device and a drilling method of a composite drain are formed by drilling a plurality of drainage holes in a composite drain in which a cylindrical drain and a plate drain are integrally combined to facilitate a dehydration action. It is about a method.

In order to build various buildings or structures such as houses, factories, roads, and embankments on soft grounds such as rivers, lakes and swamps, the construction of reinforcing the strength of soft grounds by discharging moisture contained in the soft grounds to the ground must be preceded. By doing so, it is possible to ensure the stability of the buildings or structures that are erected afterwards. When the construction method is carried out for the construction work on a land containing a considerable amount of water such as soft ground, same.

The oldest water removal method is to excavate the ground to make a cylindrical drill hole, and then fill the inside with sand with excellent absorbency, so that the water contained in the ground is discharged by capillary action along the sand column. For example, since the efficiency is very low, it is rarely used in recent years, and nowadays, it is common to use a plate drain or a cylindrical drain formed in the pipe wall through a plurality of through holes penetrating the inner and outer circumferential surfaces.

In general, the plate drain is formed in each of the sides of the plate having a rectangular shape, a plurality of valleys, that is, drainage grooves are formed along the length direction, compared to the width, such as a plurality of ribs or flanges parallel to each other from the upper end to the lower end of the plate It is a structure in which a plurality of plate-shaped protrusions of relatively long length are erected upright, and the outer surface is embedded in the soil while being wrapped with a filter material such as nonwoven fabric.

Therefore, when the plate drain is vertically embedded in the soil, only the water contained in the soil passes through the filtering member and moves to the plate body, and this water is discharged along the drain groove formed between the protrusions by capillary action. After rising, it is discharged to the ground surface through the upper end of the plate drain.

However, as the moisture contained in the soil is discharged, the ground sinks, and the sinking ground strongly presses both sides of the plate drain, so that the filtration member is indented to the projection and each flat surface side of the plate, and between the projections. The drain groove of the extremely small, or in severe cases, there is a problem that almost disappears.

Meanwhile, the cylindrical drain, which is another drain member, was developed to solve various problems of the plate-shaped drain board as described above. The spiral drain is formed in the pipe wall instead of a flat straight tube along the axial direction. At the same time, a hole tube through which a plurality of through holes penetrate the inner and outer peripheral surfaces thereof is used.

In addition, the cylindrical drain is also buried in a soft ground in a state in which the filtration member is wrapped on its outer circumferential surface. Unlike the plate drain, since the rigidity is large, the hollow of the perforated pipe serving as the drainage groove is not blocked, and the time is There is an advantage that the drainage performance is not degraded over time.

However, the plate drain has an advantage that the soil contact area is twice as large as the soil contact area of the cylindrical drain, which is advantageous in the dehydration conversion cross-sectional area, while the cylindrical drain has different advantages of excellent rigidity and constant drainage performance. .

Therefore, a composite drain that can have the advantages of a cylindrical drain and a plate drain has been developed. In Korean Patent Laid-Open No. 1999-78935, "Wrinkle pleat drainage pipe having a large dehydration conversion cross-sectional area" is disclosed and registered in Korea. Utility Model No. 376585 discloses an uneven wing corrugated drainage pipe having a large dehydration conversion cross-sectional area.

The patent discloses a structure in which plate-shaped corrugated wings are integrally coupled along the axial direction on both sides of the outer circumferential surface of the cylindrical drain, and the filter cloth is wrapped around the outer surface thereof, although the contact area with the soil increases, In close contact with the outer surface of the pleated wing, there is a disadvantage that it is difficult to improve the sufficient drainage performance because a certain drainage groove is not formed between the inner surface of the filter cloth and the outer surface of the pleated wing.

The utility model has a structure in which a plurality of concave-convex drainage guide grooves parallel to the longitudinal direction are formed on both sides of the corrugated wing constituting the disclosed patent, wherein the corrugated wing with the drain groove is integrated with the perforated pipe. Bar, although the drainage capacity can be improved compared to the above-described patent, in the case of the wrinkled wing, the wrinkled wing may not play its role as the uneven drainage guide groove is reduced or closed over time.

Therefore, in order to improve the above problems, a composite drain in which plate-like drains are integrally coupled to both outer peripheral surfaces of the cylindrical drain has been developed.

That is, the drainage action occurs in the plate drain side of the composite drain through the drain hole, and the drained water is collected into a cylindrical drain connected integrally, and drained together with the drained water through the drain hole formed outside the cylindrical drain. As a result, the soil contact area is increased, which is advantageous in dehydration conversion cross-sectional area, and has all the advantages of excellent rigidity and constant drainage performance.

At this time, the technology for processing the drain hole on the outer surface of the cylindrical drain was developed, "open hole drilling device" is disclosed in Korean Patent Laid-Open No. 2003-64570, looking at it as follows.

Drilling a hole for drainage in the cylindrical hole, the punched knife bundle is placed inside the corrugated pipe is formed and cooled through a mold, and by transferring the cylindrical continuous pipe, the punched blade coupled to the punched knife bundle The hole for drainage is processed by cutting the protrusion which protruded and formed in the inner side of a cylindrical hole tube.

However, according to the above technique, in order to process the drain hole for the composite drain in which the plate drain is integrally coupled to both sides of the outer circumferential surface of the cylindrical drain, the drain hole is first processed in the cylindrical drain, and then the plate type is formed by using a separate process. There is a problem that the process is added by processing the drain hole on the surface of the drain.

In addition, if the apparatus for processing the drain hole in the plate-drain is continuously formed at the rear end of the mechanical device for processing the drain hole for the cylindrical drain, the size of the mechanical device as a whole becomes large, and the price of the mechanical device may increase rapidly. There was no choice but to use space.

In addition, when the cutting projection is formed to protrude on the outer surface of the composite drain, there is no suitable drain hole processing method, there is a problem that the productivity is reduced due to the inefficiency of the drain hole processing.

The present invention has been made in view of the above problems, and at the same time, since a plurality of drainage holes are drilled on the surface of the cylindrical drain side and the surface of the plate-shaped drain side, it is an object to improve the working speed and to improve productivity.

In addition, since a drainage hole is drilled on the surface of the cylindrical drain side and the surface of the plate-shaped drain side in one mechanical device, the drain hole is always uniformly processed, and another object is to reduce defects.

The above object of the present invention is achieved by a perforated blade which can be brought into contact with the outer surface of a composite drain having circular and straight cross sections, and at the same time, drills a drainage hole on the outer surface of the composite drain conveyed by a conveying roller.

In order to achieve the above object, the present invention provides a drainage hole drilling apparatus for a composite drain, in which a plate drain is integrally coupled to both sides of an outer circumferential surface of a cylindrical drain, and a plurality of cutting protrusions protrude and are formed on the outer surface. A feed roller, comprising: a conveying roller for conveying a complex drain; A frame provided at the front of the conveying roller and provided with upper and lower cylinders which can be reciprocated up and down and face each other; A drilling block coupled to each of lower and upper ends of the upper and lower cylinders; Coupled to each of the blocks are spaced or contacted to the upper and lower surfaces of the composite drain in accordance with the movement of each cylinder, each surface contacting the upper surface and the bottom of the composite drain is combined with each surface of the composite drain It has technical features in that it comprises a lower perforated blade.

The present invention also provides a method for drilling a drain hole of a composite drain, the method comprising: transferring the composite drain to a frame; Simultaneously lowering and raising the upper and lower cylinders in the frame to bring upper and lower perforated blades into contact with upper and lower front ends of the transferred composite drain; Advancing the composite drain in a state where the upper and lower punching blades are in contact with each other so that the drain hole is drilled; And repositioning the upper and lower cylinders after the rear end of the composite drain passes the upper and lower cutting perforation blades.

That is, the drilling device of the present invention is a drilling block in which a plurality of drilling blades 4 are coupled to both side surfaces of the composite drain 5 so as to drill a plurality of drain holes on the surface of the hybrid drain 5. The core 10 is provided in separate processes, and in order to smoothly proceed the process by the plurality of punching blades 4 and the process after the end of drilling, the draining blades 4 are combined with the drain type 5. It is a structure in which the punching block cylinder 8 which is reciprocated to be in contact with or spaced apart from the surface of the () is coupled.

Therefore, in the process of drilling the drainage hole, the multiple drain 5 is transported by the transfer roller 1, and then a plurality of drillings are coupled to the drilling block 10 interlocked with the drilling block cylinder 8. The blade 4 is brought into close proximity to the composite drain 5, and a drainage hole is formed by the compression of the drilled blade 4 moved in such a manner, and when the composite drain 5 is transferred to the final position, the drainage hole is formed.
