According to the present invention, a plurality of cutting protrusions protrudingly formed on the outer surface of the complex drain can be easily cut in order to penetrate the drain hole in the complex drain in which the plate drain is integrally coupled to both sides of the outer surface of the cylindrical drain. The present invention relates to a drain hole cutting device and a cutting method for a composite drain having improved productivity of the composite drain.

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 is embedded in the soil with its outer surface wrapped with a filtering member such as a 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 does not decrease 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-type 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 was created in view of the above problems, and therefore, since a plurality of drain holes are simultaneously processed on the surface of the cylindrical drain side and the surface of the plate-shaped drain side, an object of the present invention is to improve the working speed and to improve productivity.

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

The above object of the present invention is a cutting blade that can be brought into contact with the outer surface of the composite drain having a circular and straight cross section, and at the same time, cuts the cutting projections protruding and formed on the outer surface of the composite drain conveyed by the conveying roller. It is achieved by a cutting knife having.

An apparatus for cutting a drain hole of a composite drain according to the present invention for achieving the above object includes a transfer roller for transferring a composite drain; A frame provided at the front of the conveying roller and provided with upper and lower cylinders which can be reciprocated with each other; Blocks respectively coupled to lower and upper ends of the upper and lower cylinders; It is detachably coupled to each block so as to be spaced or contacted with the top and bottom of the composite drain according to the movement of each cylinder, and each side contacting the top and bottom surfaces of the composite drain is combined with each side of the composite drain. There is a technical feature in that it comprises an upper and lower cutting knife.

The present invention also provides a method for cutting a drain hole of a composite drain, the method comprising: transferring a composite drain having a cutting protrusion protruding to a frame; Bringing the upper and lower cutting knife into contact with the upper and lower end surfaces of the front end of the composite drain which has been transported by simultaneously lowering and raising the upper and lower cylinders in the frame; Advancing the composite drain while the cutting knife is in contact with the cutting knife to cut the cutting protrusion; There is a technical feature in that it comprises a step of returning the upper and lower cylinders after the rear end of the composite drain passes through the upper and lower cutting knife.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, exemplary embodiments of a drain hole cutting device and a cutting method according to the present invention will be described with reference to the accompanying drawings.

Therefore, in the method of cutting the drain hole of the composite drain of the present invention, a plurality of cutting protrusions formed on the surface of the composite drain 5 by the cutting knife 4 in the step of transferring the composite drain 5 ( 3) is to configure the process to be cut.

2 is a view showing in detail the structure of the drain hole cutting device of the composite drain of the present invention.

Referring to FIG. 2, the cutting device of the present invention is placed side by side with the outer surface of the composite drain 5 to cut the cutting protrusions 3 in the feeding direction by the transfer operation of the composite drain 5. A plurality of cutting knives 4 are coupled to the block 8 and the block 8 and the cutting block 8 is adjacent to or separated from the composite drain 5 in the process of transporting the composite drain 5. And a cylinder 14 reciprocating.

That is, the cutting device of the present invention, in order to cut a plurality of cutting protrusions 3 integrally formed on the surface of the composite drain 5 in the longitudinal direction, the outer surface of the composite drain 5, that is, the traveling direction and It is based on having a plurality of cutting knives (4) placed side by side, combined with a cutting knife (4) to smoothly proceed the cutting operation and the process after the end of the cutting by the plurality of cutting knives (4) It is a structure including a cylinder 14 reciprocating to be in contact with or spaced from the surface of the mold drain (5).

Here, when the drain hole is processed, the plurality of cutting knives (4) coupled to the block (8) interlocked with the composite drain (5) by the transfer roller 1, the cylinder 14 is The cutting protrusion 3 is brought close enough to be cut, and the cutting protrusion 3 is cut by the cutting blade of the cutting knife 4 which is moved in close proximity, and the composite drain 5 is transferred to the final position. When the drain hole processing is finished.

It is a figure which shows that a drain hole is processed by a cutting knife.

Referring to FIG. 3, the composite drain 5 is transferred by the conveying roller 1, and then the cutting knife 4 is moved to the bottom surface of the cutting protrusion 3, where V of the cutting knife 4 is used. When the cutting projection 3 is obliquely cut by the cutting blade formed in the groove of the ruler or inverted V shape, and the cutting knife 3 completes cutting to the last end of the cutting projection 3, the drain hole 15 As a result, the resulting cutting chip 13 is generated.

At this time, the V-shaped or inverted V-shaped cutting blade is formed on the inner side of the cutting knife 4 in the direction in which the shear stress generated while cutting the cutting projection 3 is perpendicular to the conveying direction.
