The reinforcing resin 30 is inserted into the groove 23 to form the support 8 for forming the both side wall surfaces 12 of the hollow spheres 7 and 7 'formed on the lower side. The invention provides a structure for reinforcing the two side walls 26, and the embodiment accordingly.

Description

Sewage reinforcement spiral pipe for civil engineering and road construction

The present invention relates to a structural reinforcement spiral pipe for reinforcement of the breakage strength of the drainage pipe, sewage pipe, external pressure, rotation pressure, and the like.

In general, in order to reinforce the earth pressure and lubrication pressure of drainage pipes used in underground works in civil engineering and road construction, products that directly integrate both side walls of the hollow part spirally wound and reinforce them with both side walls, etc. Although a spiral tube was provided, there was a weak point that the reinforcing heavy tool area wound in the spiral wound was damaged in the circumferential cross section depending on the earth pressure.

Therefore, as a description of the product for this, as shown in Figs. 6 to 8, the hollow spheres forming the two side wall surfaces are spirally wound at regular intervals to be buried in a spiral tube which is integrally formed with a joint and used for long-term use. Spiral tubes provided by reinforcing the reinforcing bars integrated on the upper side from the middle of both side wall surfaces forming the hollow spheres or by reinforcing the outer wall surfaces integrated on the upper side of the hollow spheres were provided.

However, according to the condition of the construction site of the spiral pipe, in the region where the soft ground and the high load are applied, it is insufficient to provide the perfect solution to the external pressure reinforcement as the product provided above.

Therefore, in order to solve this problem, it is required to provide a perfect reinforcing spiral tube that is more economically light and has a good applicability according to construction conditions, and is more effective for practical use and reconstructs durability and economy.

Spiral pipes for drainage pipes that are used for a long time by laying in the ground are provided while maintaining a constant thickness for external pressure reinforcement, wherein the spiral pipes formed by integrally fusion of both side walls of the reinforcing hollow part 26 where the hollow sphere 7 is formed It is a reality that the hollow sphere (7), which is a weak section in the spiral tube, breaks in the spiral direction due to concentrated load or depression during long-term use.

Further, both side wall surfaces of the hollow portion 23 constituting the hollow sphere 7 are reinforced to provide the support 8 and the recess 23 at the same time as the hollow spheres 7 and 7 'on the upper and lower sides. This is to provide a high economical task with good external pressure and robustness.

The present invention provides a hollow tube (7) in a spiral tube formed by integrating a hollow sphere (7) formed of both side wall surfaces (26), which are conventionally used, into a spiral wound circuit with a joining table (22) at a predetermined interval. The recess 23 is integrally formed with the support 8 so as to form the upper and lower hollow balls 7 and 7 'by separating the middle part of the hollow sphere 7 from the middle part of both side wall surfaces 26. It is to provide a spiral tube that reinforces the two side wall surface 26 of the related art.

Therefore, the present invention will be described in detail with reference to the drawings.

As shown in Figs. 2 (a) and 6, the spirals formed by unifying the spiral wound circuit junction 22 integrally while maintaining a predetermined distance from both side wall surfaces 26 forming the hollow sphere 7 in the conventional spiral tube. In the case of long-term use in underground pipes, in order to reinforce both side walls 26, which is the structure of external pressure reinforcement, the middle portions of both side walls 26 are bent symmetrically to each other so that the hollow spheres 7 and 7 ' Both sides of the wall surface 12 is formed on the upper and lower sides to form a) and is provided by forming the support 8 and the recess 23.

Therefore, the provided structural reinforcing spiral tube is provided with structural reinforcement by forming the support (8) to form the groove portion 23 between the two side wall surface 12 is formed in the upper and lower side when the underground buried long-term use It is to provide a product reinforced with external pressure reinforcement and robustness than the conventional spiral tube.

In addition, as shown in FIG. 2 (b), the auxiliary hollow sphere 17 is formed while the support wall 13 is integrally formed with the upper and lower side wall surfaces 12 in the recess 23. Provide structural reinforcement spirals for the service.

At this time, when the drilling tool 18 is drilled at regular intervals according to the joining table 22, the invention is provided for the culvert drainage pipe.

In addition, as the invention for providing a reinforcing structure for external pressure reinforcement in the spiral pipe provided in the present invention as shown in Figure 3 is provided with a support (8) between the upper and lower side wall surface 12 provided above As the invention for providing a spiral tube provided by inserting the reinforcement resin stand 30 into the space of the recess 23, the same reinforcement as the support stand 8 between the hollow spheres 7 and 7 'formed on the upper and lower sides. It is an invention that structurally reinforces the conventional both side wall surfaces 26 by providing the resin bag 30.

In addition, as an embodiment of the present invention as shown in Figure 4 by integrally fixing the support 24 inserted into the space of the groove portion 23 between the upper and lower hollow spheres (7) (7 ') described above. As the invention to provide, provided in the spiral tube of the present invention than the spiral tube provided as a support 24 integral to the middle and upper portions of both side wall surface 26 and integrally at the upper side of the conventionally provided hollow sphere (7). It is an invention that reinforces the integrated reinforcement strength economically because it is provided by inserting and fixing the support 24 deeply into the groove 23 to be integrated.

In addition, in the structural reinforcement spiral pipe of the present invention provided in particular, when the size of the spiral pipe used as a drainage pipe is medium, large (spiral pipe (Φ600m / m or more for medium and large specifications) to thicken the thickness of the product used In order to provide a reinforcing product for this, as shown in FIG. 5, the hollow spheres 7 and 7 'are divided into about three divisions, and thus, the supports 8, 8' and recesses ( 23) (23 ') in a multi-layered structure in which both sides are integrally formed with the support (24, 24') inserted into the groove portion (23) (23 '), wherein the outer wall surface as needed The invention provides an integrally formed part 25 on the upper surface of the hollow sphere 7.

The present invention is a product provided by reinforcing the support and the groove while separating the side wall surface of the hollow sphere, which is highlighted as a weak point when the underground settlement or the unbalanced load of the region is applied to the conventional spiral tube, according to the embodiment accordingly As an invention, it is a product that reinforces the hollow wall both side walls of the conventional hollow sphere up and down and reinforces it with the grooves other than the support unit which are integrated under the ground when it is used in the construction site for a long time. Not only is the durability and robustness reinforced, but it is also effective in providing economical and productive products.
