Culvert and its manufacturing method {Cuvert And Production Method Therof}

The present invention relates to a culvert and a method for manufacturing the same, and more particularly, to a culvert having a plurality of culvert units that are continuously connected to form a tubular cavity.

Culverts are used to form waterways of stormwater, sewage and agricultural industry, or to create passageways such as sidewalks and driveways, while underground underground areas for laying telecommunications, hot and cold pipelines, and storage of agricultural and marine products. It is widely used for production.

Recently, prefabricated culverts have been used in which each part of the culvert is manufactured and assembled at the construction site in order to shorten the air and install the culvert in economical manner.

FIG. 6 is a perspective view of a conventional culvert unit, and FIG. 7 is an enlarged cross-sectional view taken along the line VII-VII of FIG. 6. As shown in these drawings, the conventional culvert unit for culverts has a bottom plate member 110 and an upper plate member 130 coupled to an upper portion of the bottom plate member 110 to form a cavity 120.

The bottom plate member 110 is formed with a flat bottom flat portion 111 and an upward side wall portion 113 extending upward from both side edges of the bottom flat portion 111 to form a side wall of the culvert, and the bottom plate member 110 formed therein. The upper plate member 130 which is butt-coupled to an upper portion of the upper plate member 130 is formed with a flat upper flat portion 131 and a downward side wall portion 133 extending downward from both side edges of the upper flat portion 131 to form a side wall of the culvert. . Fixing protrusions 115 and protrusion accommodation grooves 135 are formed at both ends of the upper side wall portion 113 and the lower side wall portion 131, and are engaged with each other in uneven engagement.

Then, the bottom plate member 110 is engaged with the engagement receiving groove 117 and the engagement receiving groove 117 formed in the front for the connection coupling with the bottom plate member 110 located in the rear, the interlocking projection is engaged with each other 119 is formed in the rear region of the bottom plate member 110.

By the way, in the conventional culvert unit for culverts, fixed projections and projection receiving grooves are formed at the end of each side wall portion, and are assembled together to assemble the top plate member and the bottom plate member. The butt coupling region and the upper plate member and the upper plate member have a structure in which the bonding force is relatively weak compared to other portions. As a result, when settlement and elevation of the ground occur, problems such as damage to the adjacent assembly parts of the culvert unit as well as the upper plate member and the lower plate member are caused. There is a problem that can leak.

In view of such a conventional problem, it is possible to increase the coupling force of the assembled coupling portion by providing bolts and nuts between the connected culvert units, or to secure the coupling between the culvert units and culvert units using a wire loop or the like. Then, the sealing material is embedded in the assembled coupling portions of the connected culvert units, thereby preventing leakage of the coupling portions.

However, in the case of assembling and combining the culvert units using bolts and nuts, however, since the thermal expansion coefficients of the culvert units made of concrete and the thermal expansion coefficients of the bolts and nuts are different, when a certain time elapses after installation of the culvert units, The coupling force of the coupling portion is reduced, whereby leakage may occur. In addition, in the case of using the wire loop and the fastening wire, if the wire loop and the connecting wire is repeated several times according to the weather and temperature, the tensile strength of the wire loop and the connecting wire is reduced, thereby reducing the coupling force of the culvert unit. Thus, leakage of the assembled portion may occur.

Accordingly, an object of the present invention relates to a culvert and a method of manufacturing the same, which can reinforce the bonding force between adjacent culvert units, and can easily prevent the occurrence of leakage in the assembled joint portion of the culvert unit.
