Description

Spiral hole formation apparatus of spiral pipes

The present invention relates to a spiral tube forming apparatus tube of the spiral tube, and more particularly, the drill is moved to the spiral tube while the spiral tube is rotated while passing, so that the spiral hole is formed to have a long rectangular shape, so that the inflow hole of rainwater and groundwater is formed. The present invention relates to a spiral hole forming apparatus of a spiral tube that can be rapidly formed successively.

Generally, spiral pipes with inlet holes are used as underground installation drain pipes for general civil engineering, such as playgrounds, golf courses, ski resorts, etc. And it is used as the drainage pipe for rainwater and groundwater treatment of road and rail ground. Since the spiral tube is a one-piece rather than a bonded adhesive, it has excellent compressive and tensile strength to prevent damage to the pipe during transportation or embedding.

In addition, due to the light and flexible flexibility, bending piping is possible, and construction is excellent, allowing air shortening and cost reduction. And since the use of high-density polyethylene (HDPE) resin has the characteristics of excellent chemical resistance, corrosion resistance as well as cold resistance.

However, in the conventional spiral tube, since a plurality of circular inlet holes are formed along the outer circumferential surface of the spiral groove, drills must be moved forward and backward toward the spiral tube by the number of the inlet holes. In addition, since the inlet hole is formed in a circular shape when the spiral tube is kept stationary while the drill is advanced to drill the hole, productivity is reduced.

In addition, because the inflow hole is formed on the outer circumferential surface of the spiral groove in the up, down, left, and right directions, even if rainwater and groundwater flow in the upper, left, and right directions of the spiral groove, some rainwater and groundwater fall into the inflow hole at the lower side. There were disadvantages such as going out.

The present invention was developed in view of the conventional problems, and an object of the present invention is to move while rotating the spiral tube while drilling a hole in the spiral tube, so as to improve the processability of the spiral hole which is the excellent and groundwater inflow hole of the spiral tube. The present invention provides a spiral hole forming apparatus for a spiral tube.

According to the present invention, the inlet is formed in a long rectangular shape so that the rainwater and groundwater can be smoothly introduced, and the inlet hole is not formed at the lower side of the spiral tube so that the rainwater and groundwater introduced can not flow out. In providing a forming apparatus.
