The present invention is provided to connect the spiral pipe (1) (1 ') for each underground drain pipe, especially, in the large size spiral pipe has a large cross-sectional area surrounding the connecting portion cylindrical waterproof sheet (3) Since it is difficult to use most of the waterproof sheet (3) of the planar type, as designed to provide a perfect leak prevention, the connection portion of the spiral pipe (1) (1 ') by adhering the inclined surface (3') Shrinkage consists of a heat-shrink table (4) or a heat-shrink table (4) and a guard (5), or wrap the tightening waterproof sheet (3) or by inserting the shrink table (4) in the protective tube (5 ') In the belt 20 or the contraction tube 20 ', the hot air is blown to the contraction belt 20 or the contraction tube 20' with a heating device such as a gas burner to tighten the waterproof sheet 3 by heating and contracting. small It relates to a drainage pipe connection fastening device configured by pressing the inclined surface (3 ') to the crimping groove (9) of (6), and also described in detail based on the accompanying drawings as a design for the embodiment thereof.

1 is a partially cut perspective view of the main part of the present invention, Figures 2a, b is a partial perspective view of the main part in the present invention, Figure 3a is a perspective view of the main part exploded in Figure 1, Figure 3b is a line AA in Figure 1 It is a cross section.

That is, in the connection part of the spiral pipe (1) (1 ') which is to be used as a drainage pipe under the ground, it is overlapped with the adhesive adhesive bar (3') which is inclined while being cut to both sides and applied with an adhesive, firmly Wind up the connecting part of the spiral tube (1) (1 ').

Here, the outer surface of the spiral tube (1) (1 ') to be connected is used a smooth product, and the waterproof sheet (3) is used as a soft resin or rubber with good flexibility and elasticity.

In addition, the connection socket 6 is used to form a tightening jaw (7) on both sides on one side, but to tighten the fastener 17 with a plurality of bolts (8) and nuts.

In addition, the constriction belt 20, which is the main part of the present invention, is a belt configured to tighten in the form of a space in the middle of the connection portion of the spiral tube 1, 1 ', and the material used is polyester fiber and nylon fiber having good heat shrinkability. Using a shrinkage band (4) made of synthetic fibers or the like formed or externally provided with a soft guard (5), the heating temperature is 90 to 120 degrees Celsius is used at an appropriate temperature, so the thermometer and Use steamer etc.

In addition, in the embodiment of the above-mentioned shrink belt 20, the shrinkage table 4 is used as the cord-shaped shrink tube 20 'formed by inserting the protective tube 5'.

Therefore, the present invention is formed in the connecting portion of the helical pipe (1 ') inclined to both sides in the connection portion of the spiral tube (1) (1') to be connected as shown in Figures 1, 2a, b and 3a, b The shrinking belt 20 or the shrinking tube 20 ', which is the main part of the present invention, is wound on the intermediate portion of the connecting portion of each of the spiral pipes 1 and 1' that connects the waterproof sheet 3 to each other by using an adhesive or the like. ) Tightening by rotating several times, as shown in Figure 2a, as shown in Figure 2a tighten tightly with wires and strings, such as fasteners 25, or tie them together, and then evenly heated with a hot air blower, such as a known gas burner, synthetic fibers It is designed to provide a complete leakage prevention by tightly tightening the wound shrink belt and the tube portion of the spiral tube (1) (1 ') by tightly tightening the waterproof sheet (3) while the shrinkage band (4) formed by heat shrink.

At this time, in order to reinforce the disadvantage that the waterproof sheet (3) is leaked to the adhesive zone (3 ') of the spiral pipe connected to each other in the circumferential direction of the spiral pipe against the pressure of the drain flowing into the drainage pipe. As can be seen, the cow is formed from a sheet of stainless steel or a hard sheet of synthetic resin Forming the crimping recess 9 in the longitudinal direction on one side of 6, assembling it to the adhesive 3 'part of the waterproof sheet 3, The clamping stand 7 formed in (6) is tightened with the bolts 8 to the tightening hole 17 so that the crimping recess 9 tightly presses the bonding table 3 'so that the portion of the bonding table 3' described above is secured. It is devised to provide a complete solution to the leak problem.

Where the connection element used The description of the embodiment of (6) is as shown in FIGS. 4 and 5. Forming a crimping rod 9 'on one side of the 6', but the compacting table 8 'is formed One side of the 6 'is formed with a support 11 connected to the feldspar 12 and a hook 11' formed at the other side. 6 ', and the use process thereof is performed by fitting the crimping stand 9' to the bonding table 3 'of the waterproof sheet 3 as described above. While assembling to the hanger 11 'formed on the other side of 6', tighten the bolt 8 to the assembly opening 10 to fix the connecting portion of the spiral pipes 1 and 1 '.

In addition, as a description of the embodiment of the shrink tube 20 as the main part of the present invention, as shown in Figs. 6 and 7 is formed by inserting the rare wire 13 integrally to the above-described shrink belt 20 In order to provide the contraction belt 20, as described above, if the waterproof sheet 3 wound around the connection portion of the spiral tube 1, 1 'through electric power with the electric wire 14, the rare wire 13 ) Is designed to solve the perfect leakage prevention in the connecting device for the intended purpose by the heat shrinkage of the shrinkage table (4) by heating.

At this time, the heating temperature is about 90 to 120 degrees Celsius is used as the appropriate temperature, so use a thermometer and steamer not described in the drawings.

In addition, as a design for the use case for the adverse conditions of the site of the shrink belt 20, the protector 5 is externally protected to the provided shrinkage table 4, the gas burner used in the prior art is a large standard in the field use The temperature is evenly distributed over the entire length of the shrinking belt 20 or the shrinking tube 20 'wound around a certain interval in the waterproof sheet 3 surrounding the connecting portion of the spiral tube 1, 1'. It must be heated by heating to evenly shrink all over the circumference of the spiral pipe connection to provide uniform leakage prevention effect. In the construction site buried in the ground, manual heating with gas burner by manpower is a problem for even heating. As this occurs, as a design provided for reinforcement therein, as shown in FIG. Intermittently forming a plurality of outlets 24, one end is assembled to each other by the assembly stand 16, such as a hinge to maintain a circular shape, the other end is formed by forming the assembly 10 (10 ') heating mold (15) As shown in FIGS. 9 to 11, the constriction belt 20 wound around the waterproof sheet 3 wrapped around the connection portion of the spiral tube 1, 1 ′ to be connected is connected to the groove portion 17. The heating mold 15 is assembled to the assembly stage 16 and the assembly opening 10 'so as to be positioned at the middle portion of the heating assembly, and is supplied to the distribution port 24 of the convex portion to a hot air blower 21 such as a gas varner. When the hot air is supplied, the shrinkage bar 4 is configured to tighten the waterproof sheet 3 by the heat shrink action by the hot air, so that the shrink belt 20 or the shrink tube 20 'evenly performs the heat shrink action even under adverse conditions at the construction site. It is designed to provide, where the heat mold after the completion of the heating mold (15) and then Small formed crimping groove 9 is described (6) is devised to provide a secure fixing of the waterproof sheet (3) of the connection portion.

Although the connection mechanism of the drain pipe (1) (1 ') for drainage pipes used as underground drainage pipes in civil works, such as the conventional road construction of the present invention, has been used as a separate tightening device or a fusion type, Due to the nature of the manufacturing process, it is made of spiral winding, so it is designed to provide leakage prevention for the fine linear spiral groove formed on the outer surface and to solve its economic and field use easily. Not only is it the only product that solves the leak problem in the construction site by using this design, but also it is a useful design that provides the connecting device to be used while moving on the construction site.
