Description

Corrugated Steel Pipe with Reinforcement Pile Combined {CORRUGATED STEEL PIPE JOINING REINFORCEMENT PILE}

The present invention relates to a corrugated steel pipe in which a reinforcement file is combined, and more specifically, by combining a reinforcement file in which an "Y" shaped reinforcement band is integrally formed with an inner bone of the corrugated steel pipe, the flow of fluid flowing into the corrugated steel pipe is reduced. The present invention relates to a corrugated steel pipe combined with a reinforcement file to smoothly and minimize the risk of damage by dynamically distributing loads, impacts, and earth pressures applied from the outside.

In general, corrugated steel pipes (spiral pipes) that are buried in the ground during installation of water and sewage facilities that can withstand large loads and earth pressures are widely used.

Such a corrugated steel pipe (spiral pipe) is made of a structure in which the uneven waveform is repeated, and the load, impact, and earth pressure applied from the outside are mechanically dispersed, so there is a small risk of breakage, while the inside flows due to the wave structure There was a problem that water and sewage could not flow smoothly, and waste, which may be contained in sewage, was caught in the uneven wave shape, interfering with the flow of sewage, and sometimes damaging corrugated steel pipes (spiral pipes).

Due to this problem, recently, a double-helix corrugated steel pipe having a cylindrical inner wall on the inner surface of the corrugated steel pipe has been widely used.

However, the double-spiral corrugated steel pipe has an outer wall with a corrugated cross-section and an inner wall with a smooth surface, so the outer wall conforms to the force when excessive tensile and shrinkage forces are applied to the double-helical corrugated steel pipe due to load, earth pressure, and temperature changes. Thus, the tension and contraction, but the inner wall of the smooth type does not conform to the force, but rather receives the tensile force and contraction force from the joined outer wall, and eventually there is a problem of rupture or damage to the portion joined to the inner wall.

To improve these problems, "Double Wall Spiral Tube (Republic of Korea Utility Model No. 1998-059207)" has been released.

However, the double-walled spiral tube has a variable expansion and contraction portion of the inner wall that is joined to the inside of the outer wall, but the variable expansion and contraction portion has a problem in that wrinkles are formed to interfere with fluid flow.

In addition, a double-walled spiral tube having an internal reinforcement is disclosed in Patent No. 1515226 registered by the applicant.

However, such a double-walled spiral tube has a problem in that the shape of a reinforcement body adhered to the inside of the spiral tube is composed of a triangular shape, and thus, when manufacturing the double-walled spiral tube, the reinforcement body may be damaged.

In addition, the conventional reinforcing body was provided with a reinforcing bar therein to further increase the reinforcing, but the reinforcing body having such a reinforcing bar has a problem in that stiffness increases in the vertical direction, but still does not reinforce reinforcement in the side direction.

In addition, since the double-walled spiral tube is formed by combining a separate tube body (smooth strip) at the bottom of the reinforcement body, there is a problem in that the production cost is very high.

The corrugated steel pipe 100 to which the reinforcing pile of the present invention is combined is largely composed of two parts, which is composed of the corrugated steel pipe 10 and the reinforcing pile 20.

The corrugated steel pipe 10 is buried in the ground and used to transport fluid, and has a cross section in which waveforms made of acid 11 and valley 12 are repeated.

The corrugated steel pipe 10 may be made of one material selected from synthetic resins, metals, and resin coated metals, and may be formed by configuring multiple materials in multiple layers according to design conditions.

For example, when the corrugated steel pipe 10 is composed of multiple layers of a plurality of materials, a synthetic resin having elasticity may be coated on the inner and outer surfaces using a steel sheet as a core material.

The reinforcing pile 20 is adhesively coupled to conform to the inner valley 12 of the corrugated steel pipe 10 to function to reinforce the corrugated steel pipe 10.

The reinforcing pile 20 functions to reinforce the corrugated steel pipe 10 so as to prevent damage due to external impact, and also serves to prevent fluid from being interrupted by the flow of internal corrugated steel pipes.

The reinforcing pile 20 is composed of a triangular cross-section consisting of a hollow surface 21 in which the inside is hollow and in close contact with the inner bone 12 of the corrugated steel pipe 10, and a bottom surface 22 closing the entrance of the bone 12. do.

The reinforcing pile 20 is a configuration in which the reinforcing bar 23 of the "Y" shape is integrated on the hollow to increase the rigidity.

The above-mentioned reinforcing bar 23 has a primary function and a corrugated steel pipe that can reinforce the inner wall surface of the bone 12 of the corrugated steel pipe 10 by supporting the bevel surface 21 and the bottom surface 22 of the reinforcement pile 20 When an external impact is applied to (10), the branch stand 232 receives this and serves as a secondary function to spray the impact in the biaxial direction.

On the other hand, the bevel surface 21 of the reinforcing pile 20 is coated with an adhesive 30 to be fixed to the bone 12 of the corrugated steel pipe 10. At this time, the bevel surface 21 has an inside of the corrugated steel pipe 10. Of course, a plurality of hemispherical depressions (not shown) in which the adhesive material 30 is impregnated may be further formed to increase the adhesive area with the bone 12.

As described above, the reinforcing pile 20 of the present invention integrates the "Y" type reinforcing bar 23, thereby solving the problem of the risk of damage of the conventional reinforcing file (inner hollow or inner hollow "I" type reinforcing bar). It can be solved.

In addition, the reinforcing pile 20 of the present invention can prevent the freezing of fluid flowing into the corrugated steel pipe 10 in the winter due to the increase in the thermal insulation effect through the formation of a plurality of air layers through the "Y" type reinforcement 23. .

It is a curved shape corresponding to the radius, and an adhesive portion 221b extending up and down is formed.

The above-described adhesive portion 221b is to increase the adhesive area, and provides a structure that can be adhesively fixed to the curved surface of the valley 12 through the applied adhesive material 30.

In addition, the curvature portion 221a adhered to the acid 11 may be further formed because it extends to the adjacent valley 12 through the acid 11 in the corrugated steel pipe 10.

Unlike the first embodiment, the second embodiment is provided with a structure capable of minimizing unnecessary use of the reinforcing pile 20 to minimize construction cost and construction time.

In addition, the corrugated steel pipe 10 having the reinforcement pile 20 of the second embodiment has a separate inner wall for smoothing the flow of fluid because the smooth table 221 of the reinforcement pile 20 closes the adjacent bone 12. No coffin is required.
