Description

{Hanging loop-type reinforcing fillers Corrugated}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hook-and-loop type corrugated pipe which is buried in the ground during a water supply and drainage system, and in particular, a rolled steel plate in which corrugated corrugations are repeatedly formed in a spiral shape, The reinforcing member and the hook portion are connected to each other to obtain a corrugated tube reinforced by a filling material.

As is well known, a corrugated pipe is buried in the ground for the purpose of water supply and drainage, and there are various types of corrugated pipes. However, for the convenience of manufacture and assembly, the corrugated iron plate, Hooked type corrugated pipes are often used.

However, since such a conventional hook-and-loop type corrugated tube has no structure in which both side ends of the thin metal plate to be embedded in the plate body are firmly connected to each other, a concentrated load is applied to a portion where the thin metal plate is connected in a state buried in the ground , There was a defect that the connection portion of the thin metal plate was liable to be broken.

In order to solve such a problem, in Korean Patent No. 10-0102764, "hook-and-loop type spiral tube and its manufacturing method ", referring to Fig. 1, an adhesive synthetic resin is integrally coated on both surfaces, When the coated metal plate 100 is spirally wound around the other end of the metal plate 120 so that the retaining ring 130 is formed in the longitudinal direction of the retaining ring 120, The hook has a structure in which the hook synthetic ring 200 is filled in the support groove 121 formed by the inner surface of the support ring 120 and then the hook ring 130 is simply inserted And has a structure of the fill hook 140 formed by fitting. The hooked-wire spiral tube is a hooked hook 140 in which both end portions of the coated metal plate 100 are helically wound and the molten synthetic resin 200 is filled between the hooked hook portion 120 and the hooked hook portion 130, Structure, it is possible not only to improve the resistance to accidental concentrated loads, but also to maintain the airtightness and to prevent the leakage of water.

Since the filling hooks 140 of the hook-and-loop type helical tube have a characteristic of maintaining the binding force and air tightness between the support ring part 120 and the engagement ring part 130 which are simply inserted depending on the molten synthetic resin 200, When the filled hook 140 receives a concentrated load due to the earth pressure, the molten synthetic resin 200 loses its own binding force so that the retainer ring 120 and the retainer ring 130 are relaxed There is a problem that the hooking hook 140 is easily broken. The molten resin 200 is shrunk and hardened after a lapse of time since it is filled in the support ring part 120 and the engagement ring part 130 so that a gap is formed between the support ring part 120 and the engagement ring part 130 So that there is a problem that leakage occurs in the hook 140.

In order to solve the above problems, the inventor of the present application has disclosed a Korean patent application No. 10-0675214 entitled " a hook-and-loop type corrugated pipe and a manufacturing apparatus thereof ", in which a plurality of bending corrugations 11 are formed in the width direction The coated steel plate 10 is spirally wound around the one side ring 12 and the other side by using the coated steel plate 10 having the one side ring 12 and the other side ring 13 which are bent at symmetrical sides on both sides, And a clip type packing 30 having both side exponential protrusions 32 formed at both ends of the intermediate exponential protrusion 31 is inserted and held so as to be positioned between the rings 13, And the ring 13 is formed by pressing the connecting joint part 20 so as to form a tubular body having a continuous wave shape.

According to the above-described hook-and-loop type corrugated pipe, the coated steel plate spirally wound is pressed against the one side ring 12 and the other side ring 13 with the clip-like packing 30 sandwiched therebetween to thereby exhibit excellent binding force and water- It is possible to prevent the ring 20 from being damaged even if the concentrated load due to the earth pressure is received in the state of being buried in the ground so that the service life is largely extended and a gap is formed in the ring 20 It is possible to prevent water from being generated and maintain the watertightness continuously.

However, such a hook-type corrugated pipe may be bent or broken due to the pressure of the earth pressure when the ring 20 is compressed or buried under the ground, There is a problem that flooding phenomenon occurs in a gap.

In addition, when the clip-type packing is made of a synthetic resin material, the intermediate exponent protrusion 31 and the exponent protrusions 32, as well as the bending connection strip 33, are damaged, and the entire hooking portion is damaged.

In addition, it is possible to improve the dimensionality by pressing the middle exponent protrusion 31 and the exponential protrusion 32. However, when the pressure is applied in various directions while using for a long period of time, There is a problem that the life is shortened due to breakage or the water and / or wastewater flowing inside is leaked.
