Description

Road culvert drainage pipes {omitted}

The present invention relates to a culvert drainage pipe for roads that are suitably used as drainage pipes buried underground in roads and civil works.

In general, a product having a plurality of holes continuously formed in the outer wall of the hollow sphere and the junction between the hollow spheres of the culvert drainage pipes formed by spiral winding made of synthetic resin has been used. In the case of long-term use of underground buried soil or foreign matter flows through the lifespan and accumulated in the inner space of the culvert drainage pipe, the problem of blocking the role of drainage is often exposed. It has been used by forming a life preserver on the outer wall surface or the inner wall surface which is used by winding or forming a hollow sphere.

In addition, when the underground burying in the culvert drainage pipe used for a long time, the high pressure of earth load, lubrication pressure, etc. due to the movement of the vehicle in the road, such as the cylindrical cross-section is deformed into the elliptical shape often causes a problem. The external pressure reinforcement is formed by the bending stress of both side wall surfaces 42 forming the hollow sphere 21 in the hollow sphere 21 and the joining plate 26 forming the culvert drainage pipe, and the hollow sphere 21 By reinforcing the earth pressure by the length constituting the height of both side wall surface 42 to form a), the reality is required to provide a structure that can be further reinforced for this.

In addition, it is designed for efficient drainage work by discharging the surrounding soil to drains while draining in places where groundwater and drainages are accumulated in civil engineering, etc., and culverts with multiple drains formed in the body of the culvert drainage pipe. As a drainage pipe, a conventional product is provided with a culvert drainage pipe in which a drainage hole is formed only at the junction 26 between the hollow spheres, so that the drainage pipe cannot be efficiently drained.

That is, while reinforcing the external pressure of the culvert drainage pipe buried underground, while promoting the drainage at the outlet, the soil around the culvert drainage pipe flows through the outlet and accumulates in the inner space of the culvert drainage pipe to block the drainage space.

The present invention is to prevent the phenomenon that the surrounding soil flows from the discharge port 27 to accumulate in the inner space while reinforcing the effect of the drainage to the product formed with a plurality of drains (4) formed in the culvert drainage pipe (21) for the external pressure reinforcement As a product, the height of both side wall surface 42 of the hollow sphere at the height of the conventional culvert drainage pipe is divided into two, but the upper surface 22 of the hollow sphere 21 while drilling the drain hole 27 in the joining table 26 The invention for providing a culvert drainage pipe which is formed by perforating the drainage hole 35 to the same position as the outlet 27 on the outer wall 32 formed by forming the side wall 31 in the outward direction integrally with the fusion zone 38 In accordance with the present invention,

Hereinafter, described in detail based on the accompanying drawings.

As shown in FIG. 2, a culvert drainage pipe which is conventionally provided and used, is joined between a hollow wall 21 formed of both side wall surfaces 42 and an upper surface 22 and an inner surface 25. The culvert drainage pipe in which the drain hole 27 was perforated at regular intervals was used in the synthetic resin spiral pipe formed by the joint pipe 26. However, in the case of using it underground for a long time, the surrounding area to be buried through the drain hole 27 The soil is soaked in with the drainage water and accumulated in the inner space 23 of the culvert drainage pipe to block the drainage space, and it also destroys the stiffness at the time of laying the soil by the outflow through the sewer drain 27. As a result, the phenomenon of lowering the strength of the culvert drainage pipe used in the conventional earth pressure.

In addition, as shown in Figure 3 to form the hollow sphere 21 while drilling the drain hole 27 in the upper layer surface 22 of the hollow sphere 21 in order to prevent the inflow of soil in the above-described drain hole 27 The culvert drainage pipe which provides a drainage hole 27 having a two-layer structure by drilling the drainage hole 27 on the inner side surface 25 is first filtered through the earth and sand from the drainage hole 27 formed on the upper layer surface 22. In order to solve the problem that the soil is accumulated in the inner space 23 of the culvert drainage pipe in the long term by filtering the soil in the secondary drain 27 formed in the side 25, which is the external pressure strength and hollow sphere ( 21) Because there is no reinforcement structure against degradation in the robustness, it is a product with many problems for long-term use due to construction in the ground.

Therefore, the present invention is to provide a product for reinforcing the sedimentability and external soil pressure of the soil in the above-mentioned drain hole 27, as shown in Figures 4 and 5 hollow hole 21 of the culvert drainage pipe provided In order to reduce the height of the two-sided wall 42 in two halves, the outer wall 32 is formed in the outer side in the bisected outward direction of the height of the hollow sphere 21 on the quasi-lateral side 22, while the side wall 31 is formed. As an invention for providing a culvert drainage pipe which is integrated with the upper side 22 by the fusion base 38 and perforated with the drainage hole 35 on the outer wall 32 in accordance with the drainage hole 27 of the joining point 26, The product for this embodiment is a cross section protruding from the upper side 22 and the inner side 25 and both side wall surface 42 constituting the hollow sphere 21, in order to provide a product for external pressure reinforcement In the invention to form and provide 41, the earthenware hook in the role of the drain hole 27, 35 of the two-layer structure As to the reinforcing property, while providing the outer reinforcement to the earth pressure bisecting the coupling structure of the both side walls 42 and the side wall 31 Buried invention is to provide a stiffness if used for an extended period of time.

In addition, in the culvert drainage pipe which has been conventionally used in the present invention, the description of the first embodiment of the present invention using the recessed portion of the joint table 26 between the hollow spheres 21 is shown in Figs. 6 and 7 (a). As shown in FIG. 1, the integrally formed at the upper surface 22 of the hollow sphere 21 formed as a spiral winding and integrally formed as a fusion point 37 formed by bending at a predetermined interval in the direction of the junction 26 where the drain hole 27 is perforated. A culvert drainage pipe is formed by forming a convex portion 36 to perforate the drainage hole 40 in the convex portion 36, and the culvert drainage pipe provided at this time is perforated in the joining table 26 forming the inner surface 25. The structure of the two-layer structure of the drainage opening 27 and the drainage opening 40 perforated in the convex portion 36 is integrated at the upper side 22 while reinforcing the dustiness of the soil, which is the object of the present invention, and the fusion point 37 It is an invention for providing a product that provides external pressure reinforcement in the structure of the convex portion 40 formed by the).

Here, as shown in FIG. 7 (b), in order to reconsider the drainage capacity of the culvert drainage pipe, the opening rate must be increased, and the long drainage port 27 'and the convex part 36 are spiraled to the joint 26. The invention is provided by forming a long drainage drain 40 'which extends the space of the drainage while being formed long in this direction.
