상단조임 타입 프리캐스트 콘크리트 암거유닛{UPPER ESTABLISHING TYPE PRECAST CONCRET DRAIN CULVERT UNIT}UPPER ESTABLISHING TYPE PRECAST CONCRET DRAIN CULVERT UNIT}

본 발명은 상단조임 타입 프리캐스트 콘크리트 암거유닛에 관한 것으로, 더욱 상세하게는 프리캐스트 콘크리트 암거유닛을 서로 연결하기 위해서 형성하는 장착홈 중에서 종래에 내부상단에 형성된 것을 외부상단에 형성하여, 설치작업이 쉽고 빠르게 이루어질 수 있도록 하고, 뒤틀림방지턱과 뒤틀림방지홈을 형성하여 지반의 침하 등으로 인해서 발생할 수 있는 뒤틀림응력에 잘 견딜 수 있도록 형성된 상단조임 타입 프리캐스트 콘크리트 암거유닛에 관한 것이다.The present invention relates to a top tightening type precast concrete culvert unit, and more particularly, in the mounting grooves formed to connect the precast concrete culvert units to each other, which is conventionally formed at the inner top at the outer top, The present invention relates to a pre-tightening type precast concrete culvert unit formed to be able to easily and quickly be formed, and to withstand torsional stress caused by settlement of the ground by forming a torsion prevention jaw and a torsion prevention groove.

일반적인 프리캐스트 콘크리트 암거유닛(이하, '암거유닛'이라 함)은 상하수도, 전력구, 통시구, 공동구 등으로 사용하기 위해서 땅속에 묻는 것으로, 다수개를 서로 연결하여 형성한다.A general precast concrete culvert unit (hereinafter referred to as `` culvert unit '') is buried in the ground for use as water and sewage, electric power, telecommunications, community, etc., is formed by connecting a plurality of each other.

종래의 암거유닛은 전후방이 개방되고, 후방에 수돌출부가 형성되며, 전방에 암돌출부가 형성되고, 각각의 모서리에는 강선이 길이방향으로 삽입될 수 있도록 강선삽입홀이 형성되며, 내벽의 각 모서리에는 이웃하는 암거유닛을 연결하기 위한 장착홈이 각각 형성된다.Conventional culvert unit is open front and rear, the water projection is formed in the rear, the female projection is formed in the front, the steel wire insertion hole is formed in each corner so that the steel wire can be inserted in the longitudinal direction, each corner of the inner wall In each of the mounting grooves for connecting the neighboring culvert unit is formed.

상기 암거유닛을 서로 연결하기 위해서, 도 6과 같이 강선을 강선삽입홀에 삽입하고, 장착홈에서 삼각고정구에 강선의 일측끝단을 삽입하여 고정구에 고정하고, 이웃하는 암거유닛의 장착홈에서 강선의 타측을 인장기로 인장하면서 삼각고정구와 함께 고정구에 고정하여 연결한다.In order to connect the culvert units with each other, as shown in Figure 6, the steel wire is inserted into the steel wire insertion hole, and one end of the steel wire is inserted into the triangular fixture in the mounting groove and fixed to the fixture, and the steel wire in the mounting groove of the neighboring culvert unit. The other side is tensioned with a tensioner and connected to the fixture with a triangular fixture.

상기 암거유닛에 관한 기술은 대한민국 특허청 등록특허공보 제0952206호, 제0931949호 등에 개시된바 있다.Description of the culvert unit has been disclosed in the Republic of Korea Patent Publication No. 0952206, 0931949 and the like.

그러나, 종래의 암거유닛은 다음과 같은 문제점이 있었다. However, the conventional culvert unit has the following problems.

(1) 뒤틀림응력에 관하여는 강선의 인장력 만으로는 견딜 수 없어서, 지반이 부분적으로 침하되어 뒤틀림이 발생하면 누수가 발생하거나, 쉽게 파손된다. (1) The warpage stress cannot be tolerated by the tensile force of the steel wire alone. If the ground partially collapses and the warpage occurs, water leakage or breakage occurs easily.

(2) 암거유닛을 서로 연결할 때 강선의 끝단을 고정하기 위한 장착홈이 모두 내벽의 모서리에 각각 형성되어 있으므로, 내부하단 모서리에 형성된 장착홈에서 작업을 할 때에는 비교적 간단히 작업할 수 있으나, 내부상단 모서리에 형성된 장착홈에서 작업을 하기 위해서는 작업자가 고개를 들고 작업을 해야하기 때문에 작업이 힘들고, 설치시간이 많이 소요된다.(2) When connecting the culvert units to each other, all of the mounting grooves for fixing the ends of the steel wire are formed at the corners of the inner wall, so when working in the mounting grooves formed at the inner lower corner, it is relatively simple to work, but the inner upper In order to work in the mounting groove formed at the corner, the worker has to lift his head and work is difficult, and it takes a lot of installation time.

(3) 강선삽입홀로 물이 유입되어 강선에 녹이 발생하므로 설치강도가 떨어지게 된다.(3) The installation strength decreases because water flows into the steel wire insertion hole and rust occurs in the steel wire.

상기한 문제점을 해결하기 위해서, 본 발명은 전후방이 개방되고, 후방에는 돌출된 수돌출부가 형성되며, 전방에는 수돌출부의 돌출높이 만큼 파진 암돌출부가 형성되고, 각각의 모서리에는 강선이 길이방향으로 삽입될 수 있도록 강선삽입홀이 형성되며, 내벽의 각 모서리에는 이웃하는 암거유닛을 연결하기 위한 장착홈이 각각 형성된 일반적인 프리캐스트 콘크리트 암거유닛에 있어서,In order to solve the above problems, the present invention is open to the front and rear, the rear is formed with a protruding water projection, the front is formed with a crushed rock protruding by the height of the projection of the water projection, the respective steel wires in the longitudinal direction In the general precast concrete culvert unit is formed with a steel wire insertion hole to be inserted, each of the corners of the inner wall is formed with a mounting groove for connecting the adjacent culvert unit,

상기 장착홈은 내부하단에 2개가 형성되고, 외부상단에 2개가 형성되며, Two mounting grooves are formed at the inner lower end, two are formed at the outer upper end,

상기 수돌출부의 네변의 주연부에는 수돌출부보다 적게 돌출되는 뒤틀림방지턱이 각각 형성되고, 상기 암돌출부의 네변의 주연부에는 암돌출부보다 적게 파인 뒤틀림방지홈이 각각 형성되며, 상기 암돌출부의 표면에는 패킹홈이 형성되되, At the periphery of the four sides of the water projecting portion, each of the anti-twist projections protruding less than the water projecting portion is formed, each of the four sides of the female protrusion is formed in the anti-twisting grooves less than the female protrusions, respectively, the packing groove on the surface of the female protrusion Is formed,

상기 패킹홈은 네 모서리에서 강선삽입홀을 완전히 감쌀 수 있도록 형성된 것을 특징으로 한다. The packing groove is characterized in that it is formed to completely wrap the steel wire insertion hole in the four corners.

본 발명의 상단조임타입 프리캐스트 콘크리트 암거유닛에 의하면 다음과 같은 효과가 발생한다.According to the upper tightening type precast concrete culvert unit of the present invention the following effects occur.

(1) 수돌출부와 암돌출부의 주연부에 형성된 뒤틀림방지턱과 뒤틀림방지홈에 의해서 뒤틀림응력에도 매우 잘 견딘다.(1) It is very resistant to torsional stress by torsion prevention jaw and torsion prevention groove formed at the periphery of water projection and female projection.

(2) 장착홈이 내부상단이 아닌 외부상단에 형성되므로, 작업자가 암거유닛의 외부 상단에 올라서 쉽게 작업할 수 있고, 설치시간이 줄어든다.(2) Since the mounting groove is formed at the outer upper part instead of the inner upper part, the worker can easily work on the outer upper part of the culvert unit, and the installation time is reduced.

(3) 강선삽입홀의 주연부를 전체를 감싸면서 패킹홈이 형성되어, 패킹홈에 패킹이 삽입되므로 강선삽입홀에는 물이 잘 스며들지 않아서 강선이 쉽게 녹슬지 않는다. (3) The packing groove is formed around the entire periphery of the steel wire insertion hole, and the packing is inserted into the packing groove so that the steel wire does not rust easily because water does not penetrate the steel wire insertion hole.
