Description

Prefabricated culvert

The present invention relates to a prefabricated culvert installation, and more particularly, to a prefabricated culvert installation is coupled to form a cavity therein with at least one engaging end to be engaged with each other.

In general, culverts are used to form waterways such as stormwater, sewage and agricultural industrial water, or to create passageways such as sidewalks and driveways, while underground underground areas for laying telecommunications, hot and cold pipelines, and storage warehouses for agricultural and marine products. It is used for various purposes such as production.

Such culverts are prefabricated box culvert units in which the hollow spheres are formed inside the factory in large quantities, and prefabricated culverts that form a predetermined passage by butt-contacting the culvert units to communicate with each other as needed in the field are widely used. It is used.

By the way, in such a conventional box-type culvert, when a simple joint using the mortar or the like without a separate forced coupling means, if the rise and / or settlement of the ground occurs, the joint region is easily cracked There is a problem that it is difficult to maintain the confidentiality between the inside and outside.

In addition, when the size of the culvert unit is increased, such a box-type culvert is provided with a partition wall therein to form a cavity or 2 or 3, the volume and weight of the culvert unit are relatively increased, making transportation and installation difficult. There is a problem. In addition, the joint end faces are brought into butt-butting contact with each other, and the cracks are easily generated in the joint area due to the external force in the vertical direction and the horizontal force acting from the side due to the elevation and / or settlement of the ground. The problem is that it cannot be kept confidential.

Accordingly, it is an object of the present invention to provide a prefabricated culvert device that can easily cope with external forces acting in the horizontal and vertical directions and can improve the airtightness of the coupling area.

Here, it comprises a plurality of culvert units are continuously coupled along the longitudinal direction of the cavity, wherein the engaging end is preferably to be formed on the contact surface between adjacent culvert units.

Each of the culvert units is erected on both side edges of the bottom plate portion and the bottom plate portion, and has a first member side wall portion which is formed on both side edges of the bottom plate portion to form a partial side wall of the cavity. And an upper member having a second partial side wall portion in contact with the first partial side wall portion to form a sidewall portion of the cavity, wherein the engaging end is effectively formed on the contact surface of the upper member and the lower member.

In addition, it is preferable to further include a grouting injection hole in communication with the receiving space for the injection of grouting.

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

1 is an exploded perspective view of a prefabricated culvert equipment according to the present invention. As shown, the prefabricated culvert installation according to the present invention has a plurality of culvert units (1) which are continuously coupled to each other along the longitudinal direction to form a cavity therein. Each culvert unit 1 has a bottom member 30, a lower member 30 having both lower side wall portions 33 formed to stand along both side edges of the bottom plate portion 31, an upper plate portion 11 and an upper plate portion ( 11 is formed along both side edges and includes an upper member 10 having an upper side wall portion 13 coupled to the lower side wall portion 33.

At one end of the upper member 10 is formed an inner rib 15 protruding along the inner wall of the upper plate portion 11 and both upper side wall portions 13, and the inner end of the other upper member 10 at the other end portion. The outer ribs 17 protruding along the outer surfaces of the upper plate portion 11 and the upper side wall portion 13 are formed to engage with each other with (15). At the lower ends of both upper side wall portions 13, downward outer ribs 19 protruding along the outer wall surface are formed, respectively. The contact side wall surfaces of these inner ribs 15, the outer ribs 17, and the downward outer ribs 19 are formed to be inclined to facilitate coupling, and the respective inclined walls face to mutually cooperate to receive grouting when contacted with each other. The grouting accommodating portions 42 are recessed to form the space G, respectively.

FIG. 2 is an enlarged perspective view of the lower member of FIG. 1. As shown, bottom flanges 36 extending outwardly along the plate surface direction of the bottom plate portion 31 are formed in the bottom region of the lower member 30, respectively. At one end of the lower member 30 is formed a chamfer 32 recessed in the longitudinal direction and cut upward in the thickness direction from the bottom surface, the other end opposite to the chamfer of the other lower member 30 A bleed extension 34 is formed which protrudes along the longitudinal direction so as to be able to engage with (32).

In addition, an inner rib 35 protruding along the inner walls of the bottom plate portion 31 and both lower side wall portions 33 is formed at the end portion of the lower jaw side of the lower member 30, and another lower member is formed at the end portion of the lower portion 30. Outer ribs protruding along the outer wall surfaces of the bottom plate portion 31 and both lower side wall portions 33 so as to form a receiving space G for grouting in the wall thickness direction between the inner ribs 35 of 30. 37) is formed. On the upper ends of both lower side wall portions 33, upwardly inner ribs 39 protruded upward along the wall surface of the cavity. The contact side wall surfaces of these inner ribs 35, the outer ribs 37, and the upper inner ribs 39 are formed to be inclined to facilitate coupling, and the respective inclined walls face to accommodate grouting when mutually contacted. The grouting accommodating part 42 recessed from each inclined wall surface is formed so that the space G may be formed.

3 is an enlarged cross-sectional view taken along line III-III in the assembled state of the prefabricated culvert installation of FIG. As shown, the grouting receiving space 42 is formed between the outer rib 17 and the inner rib 15 of the upper member 10 by the grouting accommodating portions 42 recessed from the respective wall surfaces. The rib 17 has a grouting injection hole 41 for injection of grouting therethrough. The grouting receiving space 42 is formed between the inner ribs 35 and the outer ribs 37 of the lower member 30 by the grouting accommodating portion 42, and the inner ribs 35 are provided for the injection of grouting. The grouting injection hole 41 is formed.
