The present invention relates to a formwork for drainage pipes for curved reinforcement, which is an improved product of other structures to the applicants' applications Nos. 98-17709, 98-22637, and 2000-12938. According to the present invention, when the direction of the drainage pipe is bent according to the curved bar, a conventional elbow or a forced drainage pipe may be used. The present invention may be used by bending the drainage pipe itself. (15) in the center of the spiral winding circuit (14) by integrating the spiral tube circuit multiple times to provide a solidity to the unity and to bend the inner surface (13) by bending the inclined flexible frame (34) and the coupling table ( 14) is integrated to the outer surface 15 to reinforce the curvature, and both sides are used to form a joint portion 12 to join the drainage pipe 20, the topography of the construction site as shown in FIG. Bend according to As an embodiment of the present invention, as shown in FIGS. 3 and 4, the flexible groove 35 is formed at one side, and the inlet 16 is configured so that the shimnk mortar 17 is formed of the inner and outer surfaces 13 and 15. The invention is configured to be used by curing the interior space for a certain time.

6, 7, 8 (A) as shown in Figure 1 in order to reinforce the durability of the outer surface 15 in Figure 1 to integrally configure the socket portion 18 or the inner reinforcement reinforcing portion 19, Here, the flexible groove 35 or the flexible groove 36 is formed on the inner surface 13 for flexible reinforcement, and the outer wall surface 21 is configured here as necessary.

In the embodiment of Fig. 3, as shown in Fig. 8 (b) (c) (d) (e) (bar), the inclined flexible band on the inner side 13 and the reinforcing spiral 19 of the outer wall surface 21 34) form intermittently flexible reinforcement and integrate the soft waterproof sheet stand 30, but form the assembly holes 33, and the air contact shrinkable tube 31 or the heat shrink band 31 ' Insert along the spiral groove, tighten the connection part of the drainage pipe 20 assembled in the connection device of the present invention tightly soft waterproof sheet stand 30 to the tightening core 32, and hardened by shrinkage for a predetermined time. If the heat shrink tube 31 'is used, it is a product that tightens the soft waterproof sheet stand 30 with shrinkage by heating after tightening in an appropriate manner.

At this time, the protective wall 23 is integrally wrapped on the outer surface 15 of the connecting device 11 so as to reinforce the durability of the connecting device while maintaining flexibility.

Further, in the above φ 1200m / m large aperture in the invention must be maintained in the cross yiwonhyeong of the joint (12) a multiple tube 20, because the insertion operation is easy spiral reinforcement opening 19 on the outer surface (15) integrally wound In order to further reinforce this, the outer wall surface 21 is integrally wrapped on the outer surface of the reinforcement 19, and in order to facilitate the drainage pipe insertion process, as shown in FIGS. The joining stand 13 'is formed in both parts of (12).

And, when the cement mortar 17 in the product of the present invention, or in the case of the leakage or cement mortar 17 in the form of the mold that does not generally use the cement mortar 17 assembling with the inserted drainage pipe 20 of the joint 12 In order to block leakage between the gaps, as shown in FIGS. 9, 10 and 11, the belt 25 having the elastic bands 26 and 26 'is inserted.

And, in the first embodiment of the present invention, as shown in Fig. 12 (a) (b) in Figure 12 (b) in the spiral tube in which the reinforcing rod formed with the reinforcing tool 30 in the conventional KS standard product is spiral wound integrated spiral reinforcing tool 30 To increase the height (H) and width (P) of 1.5 times or more compared to the same standard of the prior art by forming a cement mortar filling reinforcement (30 ') by forming a cement mortar inlet 16 in the longitudinal direction on one side As the formwork for the drainage pipe, the height and width of each of the conventional reinforcing holes 30 are 1.5 times larger, respectively, and are used as the input space 30 'of the fine mortar 17, and the inner surface 13 is intermittently flexible. Forming the flexible groove 35 in the invention for providing flexibility to the formwork for the drainage pipe.
