Description

High strength spiral pipe for drainage pipe

The present invention is for reinforcement of breakage strength, earth pressure, and rolling pressure of drainage pipe composed of high-strength spiral pipe.

Generally, it is a product that directly integrates both side walls of spirally wound hollow spheres and reinforces them with outer walls to reinforce the earth pressure and lubricity of drainage pipes. The site was vulnerable to damage in the cross-sectional direction depending on soil pressure.

In order to solve this problem, a corrugated support product is provided in the space between the joints between the reinforcing support parts without the hollow sphere according to my own application, but it is possible to provide a perfect reinforcing spiral pipe that is more effective and practical and reconsidered in practical use. It is a reality required.

The present invention distributes external impacts such as earth pressure and rotation pressure in the middle of the groove of the joint table 33 between the thick reinforcement support portions 31 in which the hollow sphere 21 of the conventional reinforcement hollow portion 22 is omitted. Corrugated support 34 is formed integrally with the groove section of the spirally wound joint 33 in order to meet the demand for forming the structure, and the corrugated support 34 is formed at the upper layer of the reinforcement support 31. ) Is designed to provide a reinforced spiral tube by integrating the joint table 33 to the fragility of a portion composed of the inner wall surface and the outer wall surface 25 on which the hollow sphere 21 of the conventional reinforcing hollow portion 22 is formed. It is to provide products with good durability and durability by dispersing damaged stresses, as well as earth pressure and rotation pressure, as well as impact or pressure applied in any part of the ground.

When explaining the present invention in detail based on the drawings

As shown in FIGS. 2 and 3, in the case of a conventional spiral tube spirally wound and integrated with the reinforcing hollow portion 22 and the joining table 23, it is necessary to use the ground for a long time, so that the load is concentrated depending on the region. In the present invention, the weakness of the hollow hole 21 of the reinforcing hollow part 22 formed in the circumferential direction of the vulnerability is exposed to the present invention for its solution by providing a simple and high-strength product in the product of the present invention As a product designed for reinforcement of external soil, which is considered to be a weak point, the reinforcing support part 31, which omits the hollow sphere 21 from the conventional reinforcing hollow part 22, is fixed to the joint table 33 by a spiral winding process. Both convex portions of the lower convex portion of the corrugated support portion 34 and the lower side of the reinforcement support portion 31 which are externally fixed to the fusion base 38 from both upper surface portions of the reinforcement support portion 31 for reinforcement of the joint portion 33. Reinforcement support part 31 integrates outer wall surface 35 with pitch width which is a certain interval of the reinforcement support part 31 which is rotated in the spiral winding direction and is integrated in the fusion part 36 in the groove portion 33 in the direction. As a product formed by integrating the convex portion of the corrugated support 34 into the convex portion 37 by fusion to the upper side, the hollow hollow 50 is omitted and the corrugated support as shown in FIGS. 4 and 5. At 34, the concave portion formed continuously and repeatedly in the spiral length direction is fixed to the fusion point 36, and the product is constructed by externally circumscribing the fusion support 38 on the wall surface of the reinforcing support portion 31.

In addition, as an embodiment of the present invention as shown in Figure 6 and Figure 7 is a product that is mainly applied to the medium size of Φ600m / m or more in the drainage pipe spiral consisting of the inner wall surface and the outer wall surface 35 is formed with a joint 33 Since the medium size between the pipes is about 5 to 10cm in thickness, and therefore, it is necessary to reinforce the external pressure strength according to the thickness structure. The hanger is formed on both sides, but the corrugated support 44 and the reinforcement support 31 are formed at a portion below the middle height of the reinforcement support 31 while externally circulating with the fusion support 49 along the wall from the upper layer surface of the reinforcement support 31. The fixing stand 31 'positioned at the middle height is integrated with the fusion table 48, and the convex portions protruding upward and downward of the corrugated support 44 are fused to the upper wall surface of the reinforcing support part 31 in the spiral winding direction. While the support belt 45 is externally fixed, it is fixed to the joint table 33 and the support belt 45 by the fusion bars 46 and 47, and in a separate process, according to the wall surface at the upper side of the reinforcement support section 31. While fixing the lower convex portion of the corrugated support 34 to the support belt 45 by the welding point 36 while fixing the outer convex portion externally with the fusion base 48, the upper convex portion reinforces the support portion 31 of the outer wall surface 35. It is a product that is integrated with the melting point 37 while being integral to the upper side of the).

At this time, the reference numeral 51 shown in Figure 6 is a production process auxiliary tool formed in the middle and lower portions of the reinforcement support part 31 to facilitate the work process of the reinforcement support part 31 when manufacturing the reinforcement support part 31 in a large diameter. .

In addition, the description of the embodiment of the corrugated support 34 of the product shown in Figure 4 of the present invention, as shown in Figures 8 and 9 waveforms circumscribed from the upper surface 41 of the reinforcement support 31 An alternating waveform in which the support 34 is integral to the left and right side portions of the reinforcement support 31, but the upper and lower convex portions of the corrugated support 34 are welded to the alternating fusion point 56 in the alternating direction to the left and right sides. The product of the embodiment of the present invention is provided even though the reinforcing bar 54 is formed but fixed to the alternating wave holder 54 while being integral with the upper side of the reinforcing support part 31 by a separate outer wall surface 35.

In this case, as illustrated in FIG. 6, the description of the embodiment of the fusion points 36 and 46 of the convex portions formed on the corrugated supports 34 and 44 and the corrugated supports 34 and 44 is shown below. As shown in the figure, instead of the corrugated supports 34 and 44 circumscribed from the upper side of the reinforcing support part 31, the joints 33 and the support belt 45 are alternately left and right in the longitudinal direction. It is designed to provide an alternating waveform support (54, 54 ') formed by the alternating fusion point (57') is formed.

The present invention omits the hollow sphere of reinforcing hollow part, which is considered to be a weak point when underground subsidence or local unbalanced load is applied to the conventional spiral pipe, and externally welds to the left and right parts of the reinforcing support part for reinforcement of the joint. By fixing the support belt of various structures as well as the fusion point, and as compared with the conventional products, not only the durability and robustness of the hollow sphere part is reinforced, but also economical and productive effect is provided.
