Description

Reinforcement device for drainage pipe

The present invention is for reinforcement of external pressure and breakage strength of drainage pipe composed of synthetic resin spiral pipe.

Conventionally, various devices and various structures have been provided to reinforce the drainage pipe's durability, external pressure strength, etc., but the problems of damage due to point shock and durability external pressure strength are simple in structure and during transportation. there was.

In particular, the drainage pipes made of synthetic resin spiral pipes are deformed by external soil pressure when they are used underground for long periods of time due to the nature of the material. Have been pointed out

The present invention is to solve this problem, the external pressure strength in the spiral pipe is to be structurally solid on both sides of the reinforcement (2) (2 ') on both sides of the reinforcement (2) (2') The protruding reinforcing ribs 6, 6 'are used to structurally reinforce the bending stress between the side walls of the reinforcing parts 2, 2' and the inclined reinforcing bars 4, 4 '. It is required to have a product that increases the durability and external pressure reinforcement of the synthetic resin spiral tube by providing it to be integrated.

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

As shown in FIGS. 1 and 2, a reinforcing rib 6 is formed at an intermediate portion of both side wall surfaces of the reinforcing portion 2 formed of an upper side, an inner side, and both side walls for external pressure and durability reinforcement of the synthetic resin spiral tube. 6 ') is protruded in the spirally wound length direction, and the inclined reinforcing bar 4 integrally welded to the joint 3 with the fixing bar 5 at both sides of the upper side of the reinforcing part 2 is reinforced. 6) (6 ') supports and fixes the inclined reinforcing bar 4 so that the hollow reinforcing balls (a) (b) having a triangle and a cross section are symmetrically configured from side to side, thereby reinforcing parts ( 2) Both side walls of (2 ') provide a structure that reinforces bending stress with external soil pressure.

In addition, in the embodiment of the present invention, as shown in Figure 3, the inclined reinforcing bar (4) (4 ') protruding on both sides of the upper side of the reinforcing portion (2'), the hollow portion is removed to the fusion splicing (3) Reinforcement ribs 6 and 6 'protruding from the wall of the reinforcement part 2' to be integrated to form symmetrical reinforcement hollow tools (a) and (b) consisting of triangles and squares on the left and right sides. It is designed to provide a device to a drain pipe.

In addition, as an embodiment of the inner surface of the reinforcing portion 2 shown in Figure 2 as shown in Figure 4 (a) (b), the flexible groove 8 or the curved acceleration incision 9 in the inner surface of the drainage pipe ), It is easy to bend according to the terrain of the construction site, making the construction easier.

And as an embodiment for expanding the use range of Figures 1 and 2 as shown in Figure 5 is integrated into the upper side of the reinforcing part 2 is formed as an inclined reinforcing bar (4) while being fixed to the joining table (3) (5) is provided for the culvert drainage pipe by forming the drill holes 7 at regular intervals in the spiral winding direction.

At this time, as shown in Figure 6 in the case of a large diameter (Ø600m / m or more) product in the drainage pipe to the reinforcing ribs (6) protruding on both side walls of the reinforcing part 2 into a plurality of reinforcing ribs (6) (6 ') Protruding is to provide a product that further strengthens the external pressure reinforcement effect because it supports both side walls of the reinforcement portion (2) at a number of points.

In synthetic resin spiral pipes widely used as drainage pipes, the inclined reinforcement protruding from the upper side of the reinforcement part is supported by supporting ribs protruding from both side walls of the reinforcement part to structurally reinforce the bending stress of both side walls. It is a product to provide a drainage pipe that provides an excellent economic effect.
