Abstract

The present invention relates to a culvert drainage pipe that is buried underground in civil engineering, such as construction and road used to remove leachate from the ground while the external pressure is reinforced in civil engineering, such as road and construction.

In general, the culvert drainage pipe used by underground laying in civil engineering is mainly provided with a function of removing leachate and groundwater, which leak through the ground where soft ground or leachate seeps into the ground, but the present invention is particularly useful for vehicles on the road. In the case of passing through, when the leachate is discharged from the hole formed in the culvert drainage pipe in an area where the leachate is excessively formed by the action of soil pressure and rotational pressure, and the vibration of the soil, the surrounding soil is discharged into the culvert drainage like the leachate. As it flows into the inner space of the pipe and accumulates, it exposes the result that obstructs the role of drainage. As a solution to this problem, there is a difficult point of laying underground culverts by winding the culvert drainage pipe with a non-woven fabric. There was a lot of restrictions depending on the conditions of underground burial with one strength.

Therefore, in the present invention, as an invention for providing external pressure reinforcement while resolving the phenomenon that the surrounding soil flows into the inner space of the culvert drainage pipe as leachate into the interior space while reinforcing the external soil, the hollow structure which is the structure of the conventional culvert drainage pipe In order to prevent external pressure reinforcement and soil inflow in the culvert drainage pipe in which the drainage port 27 is formed in the joint table 26 integrated between the spheres 21, the hollow ball is first lowered to two times the conventional height. On the upper side 22 of 21, the outer wall 32 is formed by protruding the side wall 31 at a bisecting height of the conventional hollow sphere 21, but the drain hole 27 of the joining table 26 is provided. The drainage holes 35 are formed at the same position as the above to form a drainage hole having a two-layer structure, and the soil flows into the inner space of the culvert drainage pipe of the present invention. To prevent it from passing through (35). The invention is configured so that the invention for the embodiment thereof.

The present invention relates to a culvert drainage pipe buried underground in construction and civil engineering, such as roads, which are suitably used as drainage pipes buried in the ground in construction and civil engineering such as roads.

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 external soil pressure by the length constituting the height of the side wall surface 42 to form a), the reality is required to provide a structure that can be further reinforced.

In addition, it is designed for efficient drainage work by preventing the surrounding soil from flowing into drains during drainage in places where groundwater and drainage are accumulated in civil engineering, etc., and culverts having 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.

In other words, while reinforcing the external pressure of the culvert drainage pipe buried in the ground, 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. It is an invention for providing a culvert drainage pipe for underground laying in civil works to be solved.

The present invention is a product for reinforcement of external soil pressure while preventing the phenomenon that the surrounding soil flows from the discharge port and accumulates in the inner space while the effect of drainage is reinforced to the product formed with a plurality of drains in the culvert drainage pipe, Dividing the height of both side walls of the hollow sphere into two parts at the height, and drilling the drainage hole in the splicing rod, and forming the side wall in the outward direction integrally with the fusion rod on the upper side of the hollow sphere. The invention for providing a culvert drainage pipe is configured, as an invention according to the embodiment accordingly,

Hereinafter, described in detail based on the accompanying drawings.
