Abstract

A cylindrical spiral corrugated and perforated drain member having a cross intersection of a spiral line and a straight light generating turbulence is provided to make the water discharge flow velocity fast and to secure high water permeability by the turbulence generated in the cross intersection where a spiral line and a straight light cross each other. The cylindrical spiral corrugated and perforated drain member(8,11) has an upward cross intersection formed like an endless track by crossing a spiral line with the angle of 25~80 degrees and 2~8 split straight lines symmetrical to a circumference or asymmetrical straight lines across each other. A reinforcing groove is formed to prevent the shape deformation of the structure. The perforated drain member has strong resisting power against transverse and lateral pressure generated due to soil pressure after the perforated drain member is vertically buried under the ground.

The present invention relates to an asymmetric perforated corrugated spiral perforated pipe and a manufacturing apparatus thereof (patent application 10-2005-0063558) and a manufacturing method thereof having a shape deformation preventing molded part As for the spiral perforated pipe used in the vertical drainage method, an improved invention of the device,

 More specifically, perforation used as a vertical drainage method is a soft ground improvement method that discharges moisture in the ground to the ground in a short time when the soft ground composed of viscous soil layers such as coasts and lakes is ground to road industrial complexes and airports. The present invention relates to a drainage perforated pipe used for the purpose of burying a spiral or cylindrical corrugated pipe underground and dehydrating moisture in the ground within a short period of time, and a method of manufacturing the same. It prevents breakage of the drainage effect or degradation of the drainage effect caused by cutting, bending or bending of the perforated pipes, and the vertical and horizontal movement of water at the crossroads where the water discharged to the ground through the channel crosses the straight line and the spiral. Due to the generated vortex (swirl), the flow rate is remarkably It is fast, and relates to a high-performance hole drainage material having a strong resistance to external impact at the same time by strengthening the strength of each cross section forming part.

 In general, the vertical drainage method, which is a soft ground stabilization method for construction purposes such as roads, harbors, and large-scale housing projects, is included in soft ground such as landfills in which rivers, lakes, swamps, and shores are buried. Spiral or cylindrical corrugated perforated pipes with filtration nonwoven fabrics are used as drainage materials for the purpose of water dehydration, and the above drainage materials are inserted into the steel pipe casing, and the inserted corrugated drain pipes and steel pipe casings are fastened with the underground anchor plate. Buried underground.

However, most commonly used hole drainage materials are formed in a simple structure in a single direction such as spirals or symmetrical corrugations that form a hole tube, and thus, the water flowing into the hole can not be properly discharged to the ground. Due to the relatively late problem, it takes a long time to settle the ground, especially after the construction of long depth, especially the shape of the spiral or corrugated hole due to the strong earth pressure caused by the prolonged inflow of water changes, thus reducing the unidirectional water discharge channel. This causes problems such as inhibiting the discharge of moisture above the ground, affecting the dewatering of the long-term settlement ground, and also to increase the size of the drainage in order to reduce the shape change of the perforated drainage is also used in parallel, These methods are the ground immobility due to ground disturbance There is a settlement phenomenon, and after the completion of the construction of roads, harbors, etc., problems such as ground subsidence are always present.

 The plastic synthetic resin produced from the extruder is transferred into the caterpillar forming apparatus (Fig. 1) of the multi-dividing mold through the liquid resin inlet, and is formed and conveyed as the structure of the multi-dividing mold by vacuum suction on the transfer line. Cooling tank and filter nonwoven fabric fabric line installed on the top are made in a straight line process, and the spiral convex curved portion and the linear convex curved portion cross each other in 2 to 8 directions, so that the diameter is relatively smaller than the existing drainage material.
