Description

Multi-pipe manufacturing method and multi-pipe manufacturing facility {MANUFACTURING METHOD AND MANUFACTURING EQUIPEMENT FOR MULTI-PLASTIC PIPE}

The present invention relates to a bundle pipe manufacturing method and a bundle pipe manufacturing facility, and more particularly, it is possible to mass-produce bundle pipes used for various civil works, land improvement works, or all-round construction without defects, thereby improving productivity and economy. It relates to a bundle pipe manufacturing method and a bundle pipe manufacturing facility that can be made.

In general, cutouts refer to a portion in which the edge of the road is formed to be inclined as a road is constructed by cutting a part of a mountain in order to construct a road, and most cutouts are formed adjacent to both sides of the road.

Therefore, when rainwater falls to the incision site, part of it flows down along the surface of the incision site, but the rest penetrates into the ground of the incision site and collapses the slope of the incision site due to erosion, causing landslides.

In this way, when the slope of the incision site collapses due to heavy rains, road traffic is blocked, and accidents such as buried or overturned vehicles occur, resulting in not only economic losses, but also life-threatening accidents.

Therefore, in order to prevent the collapse of the incision, plants are vegetated on the surface of the incision, but most of the incisions are made of rocks or soil, so that plants can grow due to biological weathering of the soil after about 5 to 10 years. Because it is changed to, it takes a lot of time to stabilize the surface of the incision after the incision is formed for reasons such as road work.

In addition, the biggest cause of the collapse of the incision site is that the underground penetration water that has penetrated into the ground in the incision area is caused by erosion by the water that rises to the surface of the incision area during rain. To prevent the collapse of the incision area by such water. A horizontal drainage hole is installed at the incision.

1 is a cross-sectional view showing a reinforcing member according to the prior art, the reinforcing member 10 is formed in a tube shape so as to apply pressure to the inside of the reinforcing member 10 is expanded as the pressure is applied As possible, a hinge portion 14 is formed on one side and a cutout portion 16 is formed on the other side. In addition, a plurality of protrusions 10a are formed around the outer surface of the reinforcing member 10 so that the protrusion 10a is in close contact with the perforated hole as the reinforcing member 10 is expanded.

However, since the reinforcing member 10 as described above has a structure in which the protrusion 10a is in close contact with the perforated hole when the reinforcing member 10 is expanded within the perforated hole, there is a difference between the inner diameter of the perforated hole and the outer diameter of the reinforcing member 10. There is a gap.

When water flows through the gap formed in the inner diameter of the perforated hole and the outer diameter of the reinforcing member 10, the water is not drained to the designated place by the reinforcing member 10, but flows along the perforated hole. The incision is made more unstable, causing the ground of the incision to collapse. That is, when water flows along the inside of the reinforcing member 10 and is not drained, and flows between the reinforcing member 10 and the perforated hole, erosion occurs by the water, and the diameter of the perforated hole gradually expands, and the expansion of the perforated hole eventually ends. The ground is unstable by weakening the gripping force between the reinforcing member 10 and the perforated hole.

In particular, if water does not flow along the inside of the reinforcing member 10 but flows through the gap between the perforated hole and the reinforcing member 10, not only part of the water penetrates into the ground through cracks formed in the perforated hole and erodes the ground. There is a problem of collapsing the incision by accelerating the crack of the ground as the water in the drilling hole and the water seeping into the ground from the drilling hole freezes in a situation where the temperature decreases, such as in winter.

In order to improve the above problems, drainage pipes in the shape of “S” have been recently developed and used, but productivity is low to individually manufacture multiple pipes, so there is a limit that cannot be matched to the order quantity of the contractor individually, and labor costs are also increased. There was a problem.

Accordingly, as a part of solving this problem, in order to manufacture individual bundle pipes at once, a plurality of individual molds are configured in front of the extruder from which each bundle pipe is extruded, and when drawing by holding a roller, bundle pipes drawn out to each individual mold When pulling with each roller, there is a problem in that a defect occurs due to a difference in speed of each bundle pipe drawn out.

Accordingly, the molded product that has undergone the molding step (S200) is molded into a plate-shaped integral bundle tube having a continuous S-shaped cross-section connected by the connection extrusion molding tool 112 and is drawn out.

In addition, the mold apparatus may be formed of a plurality of units or individual mold blocks each having the same extrusion mold as shown in FIG. 3.

Here, it is preferable that each of the unit mold blocks or individual mold blocks is formed so that the width of the extrusion molding tool decreases as it goes in the extrusion direction.

Next, the sizing step (S300) is determined as the final design size by passing the molded product of a somewhat flexible integrated bundle tube (a slightly soft integrated bundle tube because it is before cooling) formed in the molding step (S200) through a sizing bracket. Then, it is cooled through the cooling step (S400).

Alternatively, cutting may be performed by the cutter 300 as a cutting machine on the upstream side of the process.

Specifically, the cutting step (S710 or S720) is the connection extrusion of the integral bundle pipe from the downstream side of the drawer 200 on the line drawn by the drawer (drawer) 200 in the drawing step (S500) It can be cut by a cutter (blade) 300 installed to be able to cut the molding tool.

In addition, the cutting step (S710 or S720) is an example of the upstream side of the drawer, which is installed to cut the connection extrusion mold of the integral bundle tube on the path that is sized by the sizing bracket in the sizing step (S200). It can be cut by a cutter (blade) (300).

Accordingly, the cutting step (S710 or 720) does not require a separate driving source (driving force), and in the drawing step (S500), the integrated bundle tube that is moved by the drawing drive of the drawing machine (or drawing device) 200 is As it is drawn and passed, it is possible to automatically cut by a cutter (blade) 300.
