That is, the assembly ribs formed at both ends of the connection sockets 26, which are tightened while being cut to both sides, at the connection portions of the spiral pipes 21 and 21 'which are to be used as underground drainage pipes in underground roads and civil works. In the conventional connecting socket, which is securely tightened by bolts and nuts 29 through the fitting holes 28, the connection part of the spiral pipes 21 and 21 'is connected to both sides. The connecting socket 26 is formed by bending the pressing groove 24 in the circumferential direction to both sides in a predetermined depth in the inner direction, and integrally assembles the pressing parking 30 at the inner end of the pressing groove 24.

In addition, since the connection socket 26 used in the present invention leaks at the assembly portion of the assembly rib 27, as a solution for this, the tightening jaw 22 is formed on both sides in accordance with the assembly rib 27, Assemble the crimping parking 31 on the tightening jaw 22, and tighten the crimping parking 30 assembled in the crimping recess 24, so as to perforate in accordance with the assembling hole 28 formed in the assembling rib 27. The invention is configured to tightly tighten using a bolt, nut 29 to the assembled assembly 28 '.

Here, the pressing parking (30) and 31 assembled in the pressing groove 24 and the tightening jaw 22 to be used when the assembly rib 27 of the connection socket 26 is tightened tightly with bolts, nuts (29) Tighten the outer surface of the connection portion of the spiral tube (21) (21 ') to provide a standard set to prevent leakage.

In addition, the connection socket 26 is made of synthetic resin and iron, and the compression parking 30 and the assembly parking 31 is used as a good rubber and synthetic resin while maintaining the hardness to prevent leakage.

In addition, the assembly parking 31 provided in the construction site under adverse conditions such as civil engineering and road construction, most of the assembly ribs 27 in the process of tightening the bolts, nuts 29 firmly in the assembly process of the connection socket 26. Since the crimping is completely tightened, it proceeds by hand depending on the manpower of the construction site, so as to provide a solution for this, as shown in Figures 3 to 5, the connection is assembled to the assembly unit 32 In the inner section of the crimping groove 24, which is formed in the socket 26, the tightening jaw 22 protrudes in the inward direction in accordance with the assembly section 26 ′, and the spiral tube 21, 21 ′ is also provided. In the section of the connection portion of the assembly, assembling the crimping parking 30 'in the section between the assembly ribs 27 on both sides of which the tightening jaw 22 protrudes, thereby assembling the connecting socket 26 of the present invention tightly 32 ), The tightening jaw 22 tightly tightens the crimp parking 30 'and the assembly section 26'. The invention is configured to completely solve the leak in the liver.

At this time, the parking 34 is inserted into the outer recess of the tightening jaw 22 formed at both side assembly sections 26 'of the connecting socket 26, and the assembly is coupled to the open side portions of the connecting socket 26. The bars 32 are fastened to each other with bolts and nuts 29. At this time, the outer recesses of the tightening jaw 22 are connected to each other so that the connection socket 26 is tightened.

In addition, since the crimping parking 30 to be assembled to the crimping groove 24 described above is difficult to assemble by applying with an adhesive or the like for assembling each other at the pore site, an embodiment for solving the problem is illustrated in FIGS. 6 to 7. As described above, the assembly hole 37 is formed at the inner end of the pressing recess 24, and the compression parking unit 30 is provided with a tightening table 36 inserted into the assembly hole 37 to be assembled with each other. Tighten as described above, the invention is provided to simply assemble the connection socket of the present invention at the construction site.

In addition, spiral pipes 21 and 21 'are often buried in accordance with the construction site, and materials of the spiral pipes 21 and 21' are made of synthetic resin, so they are buried underground. The connection socket 26 of the present invention has elasticity in order to prevent leakage at the connection portion of the spiral pipes 21 and 21 'continuously connected under the influence of shrinkage and expansion due to the temperature change of the discharged water. The invention is provided by forming a flexible portion 35 in the body.

In addition, the invention for preventing the perfect leak on the outer surface of the connection portion of the crimping groove 24 and the crimping parking 30 and the spiral pipe 21, 21 'to prevent the leakage described above, shown in FIG. Provided by forming the insertion table 40 in the inward direction on both side portions of the connection socket 26, where it is provided as a fusion between the connection socket 26 of the spiral tube (21) (21 ') by integration. To this end, as shown in FIG. 9, the fusion table 32 mounted with the heating heater 42 in the insertion groove 41 is fitted to the insertion table 40, and the assembly ribs 27 of the connecting socket 26 are provided. Tightly), and then heat the heater 42 through electric power to melt the fusion base 32 and thermally fusion the connection portions of the spiral pipes 21 and 21 'and the compression grooves of the connection sockets 26 ( 24) An invention in which the site is integrally fused and provided.

Here, the fusion base 32 used provides a product made of an adhesive resin having good heat melting and good adhesion.

In addition, the assembly hole 37 of the connecting socket 26 provided in the present invention protrudes in the outward direction of the connecting socket 26, as shown in Figure 10 to provide an assembly (37).

In addition, the connection socket 26 provided in the present invention is to form a crimping groove 24 and the insertion groove 41 in the inward direction by bending the plate-shaped socket, to carry out the assembly work on the transport site or the connection site in the construction site In this case, during transportation from the manufacturing plant to the construction site, flattening should be carried out to reduce the cost of transportation and at the same time, and to be easily bent at the construction site. This easy, but the provided connection socket 26 is a structure that is difficult to be bent to fit the work process, as an invention for providing a solution for this, as shown in Figures 11 to 13 connection socket 26 The invention is provided by intermittently forming the incision (33) in the bent portion of the crimping groove 24 bent inwardly from both sides of the), in the case of transporting the adhesive groove 24 The formed incision 33 is opened to open the connection socket 26 is formed in a flat shape, and to provide a product configured to be bent in a circular cross section in accordance with the connection portion of the spiral pipe 21, 21 'at the construction site In this case, the waterproof sheet 23 solves the problem of leaking into the incision 33 should be assembled by inserting between the pressing groove 24 and the pressing parking 30 as shown in FIG. .

Although the connection mechanism of the spiral pipe for water and sewage pipes used as underground drainage pipes in underground works, such as the conventional road construction of the present invention, has been used as a separate tightening mechanism or a fusion type, etc. Invented to provide leakage prevention for the fine linear spiral groove formed on the outer surface and easily solved its economical and field use, and to provide the leakage preventing effect on the outer wall surface of the connection part of the spiral pipe. Not only is it the only product that solves the leak problem at the construction site, but it is also a useful invention that provides the connecting device to be used while moving at the construction site
