     The present invention is a spiral corrugated perforated tube which is perforated to be used as a moisture dehydration promotion method contained in the ground layer in the foundation of the ground to road industrial complex, airport, etc. This is a spiral hole hole pipe used as a vertical hole drainage material for the purpose of burying water in the ground and dehydrating water in a short period of time, and a manufacturing method thereof. A pulling phenomenon caused by tensile force and earth pressure generated during construction using a spiral hole hole pipe. In addition, the perforated pipe is maintained without bending or deformation, and the angle and size of the outer curved portion and the inner curved portion are mutually asymmetrical structures to enhance the water permeability of the spiral perforated drainage, and thus the strength of the perforated drainage is maximized and the water permeability is maximized.

     In general, the purpose of dehydration of water contained in the ground in the ground during reinforcement works for the purpose of construction of roads, harbors, large-scale housing construction, etc. in soft grounds such as rivers, lakes, swamps, shores, etc. It penetrates a certain portion of the concave bent portion of the spiral pleated perforated tube or the pleated perforated tube with the filtration nonwoven fabric on the soft ground to absorb the moisture into the perforated portion, and discharges the moisture to the ground through the spiral or wrinkled channel formed inside the perforated tube. Used as drainage.

    In general, when the above-mentioned hole drain pipe is inserted into the steel pipe casing and the inserted corrugated drain pipe and the steel pipe casing are fastened to various underground anchor anchor plates and buried underground, especially in the case of the long construction, the small impact caused by the casing Deformation occurs in the shape of the perforated pipe made of plastic material with low strength.

In particular, when storing hot air pipes in hot summer days, due to the heat of direct sunlight, the air pipes are loose when the casing and anchor plate are assembled due to changes in specifications at the time of molding. There are many difficulties and problems and side effects such as poor construction due to problems such as twisting and bending of the air pipes even in the slightest impact.

    In addition, the spiral shape does not form properly even in the case of small and minute changes such as the rotational speed, the take-up speed of the take-up machine, the temperature of the liquid resin injected from the extrusion die, and the temperature of the cooling water when forming the conventional spiral perforated pipe. In addition, there are inefficient problems in economic aspects, such as being relatively slow and affecting the unit price of the product.

Even in the generated transverse and lateral pressures, the water in the strata flows along the inner channel consisting of asymmetrical spirals embedded vertically without cutting or bending. In order to be discharged in a large amount, the liquid resin introduced from the existing extrusion dies can not be formed precisely the spiral and shape preventing groove structure formed precisely by the forming method by rotating the mandrel and vacuum adsorption (Fig. 10). Since there are disadvantages, dozens of molds in which the shape preventing grooves are formed in the asymmetric spiral and the convex convex curve are divided and assembled in a semi-circular asymmetrical manner to form a single axis, and the shaft is adhered to the mold at a constant speed. The liquid resin is adsorbed to the outer wall of the multi-division mold by vacuum suction (Fig. 2) in the rectangular cylindrical dividing mold to form the molding structure, so that the molding can be formed stepwise into the shape of the mold (with grooves of various shapes). To form a cooling through the cooling tank, the cold-formed asymmetric spiral hole drainage By feeding the slide external cutting cutter bundle (Fig. 8) with a straight feed taker and cutting a certain protruding part of the concave bent from the outside, it is possible to form a water inflow hole, thereby preventing deformation of the shape and asymmetric spiral channel. Accordingly, an object of the present invention is to provide an asymmetric spiral hole drainage material and a manufacturing method having a shape preventing groove that can maximize the passage area.
