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 engagement 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 facility that can easily cope with external forces acting on the culvert assembly, and can continuously maintain the airtightness of the joint areas therebetween.

The object is, according to the present invention, in the prefabricated culvert installation is coupled to form a cavity therein with at least one engaging end to engage with each other, protruding along the inner wall surface of any one of the corresponding engaging ends mutually An inner rib; An outer rib protruding along the other outer wall surface; The inner ribs and the outer ribs are achieved by a prefabricated culvert facility, characterized in that it forms a receiving space for grouting in the wall thickness direction.

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 side wall portion of the cavity, wherein the engaging end is effectively formed on the contact surface of the upper member and the lower member.

It is preferable that a water jetting groove for accommodating the water jetting agent is formed on an end face of at least one of the inner ribs and the outer ribs.

In addition, it is more effective to further include a grouting injection hole communicating the grouting receiving space and the outside for the injection of grouting.

Hereinafter, with reference to the accompanying drawings will be described in detail 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 unit (1) which are continuously coupled to each other along the longitudinal direction to form a cavity inside. 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. An outer rib 17 protruding along the outer surfaces of the upper plate portion 11 and the upper side wall portion 13 is formed to form the accommodating space G for grouting in the wall thickness direction. At the lower ends of both upper side wall portions 13, downward outer ribs 19 protruding along the outer wall surface are formed, 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.

3 is a cross-sectional view taken along line III-III of the assembled state of the prefabricated culvert installation of FIG. As shown, a grouting receiving space G is formed between the outer rib 17 and the inner rib 15 of the upper member 10, and the outer rib 17 has a grouting injection hole for injection of grouting. 41 is penetrated. Grouting accommodation space G is also formed between the inner rib 35 and the outer rib 37 of the lower member 30, and the inner rib 35 has a grouting injection hole 41 for injection of grouting. It is. At the ends of each of the outer ribs 17 and 37 and the inner ribs 15 and 35 of the upper member 10 and the lower member 30, the water-retaining agent recessed from the end surface for receiving the water-repellent agent (not shown) Grooves 43 are formed respectively.
