상기와 같이 구성된 암거유닛(10)을 공동구(14)가 연통되도록 길이방향으로 결합하기 위해서, 먼저 소정의 위치에 암거유닛(10)을 설치하고 상기 암거유닛(10)의 소켓부(15)에 조립하고자 하는 암거유닛(10)의 플러그부(16)가 끼워지도록 하고 날개부(20)가 최대한 밀착되도록 결합한다. 이때 상기 날개부(20)에 형성된 체결공(21)이 인접하는 날개부(20)의 체결공(21)과 연통되도록 밀착시켜 놓는다.In order to couple the culvert unit 10 configured as described above in the longitudinal direction such that the cavity sphere 14 communicates, the culvert unit 10 is first installed at a predetermined position and the socket part 15 of the culvert unit 10 is installed. The plug portion 16 of the culvert unit 10 to be assembled is fitted and coupled so that the wing portion 20 is as close as possible. At this time, the fastening hole 21 formed in the wing 20 is in close contact with the fastening hole 21 of the adjacent wing 20.
상기와 같이 상호 끼워진 암거유닛(10)을 고정하기 위하여 상기 날개부(20)의 최상단의 체결공(21)과 최하단의 체결공(21)을 통해 강선(10)을 삽입하여 인접하는 암거유닛(10)의 날개부(20)의 체결공(21)으로 강선(10)이 돌출되도록 한 후 상기 강선(10)의 양단부에 정착구(31)를 결합하고, 상기 정착구(31)가 날개부(20)에 형성된 설치홈(22)에 정착되도록 한 후 나머지 체결공(21)을 통해 볼트(40)를 삽입하여 이 볼트(40)가 인접하는 암거유닛(10)의 체결공(21)으로 돌출되도록 한 다음 상기 볼트(30)의 양단부에 너트(41)를 끼워 고정한다.In order to fix the culvert units 10 fitted as described above, the culvert unit is inserted by inserting the steel wire 10 through the fastening hole 21 of the uppermost end of the wing portion 20 and the fastening hole 21 of the lower end thereof ( After the steel wire 10 is protruded into the fastening hole 21 of the wing portion 20 of the 10, the fixing unit 31 is coupled to both ends of the steel wire 10, the fixing unit 31 is wing 20 After being fixed to the installation groove 22 formed in the) and inserting the bolt 40 through the remaining fastening hole 21 so that the bolt 40 is protruded into the fastening hole 21 of the adjacent culvert unit (10) Then, the nut 41 is fixed to both ends of the bolt 30.
한편 상기 볼트(30)와 너트(41)의 결합이나 정착구(31)의 결합시 와셔(42)를 추가적으로 설치하여 보다 견고히 조여지도록 한다.Meanwhile, when the bolt 30 and the nut 41 are coupled or the fixing unit 31 is coupled, the washer 42 is additionally installed to be tightened more firmly.
상기와 같이 볼트(30)와 너트(41) 및 강선(30)에 의해 암거유닛(10)과 인접하는 암거유닛(10)이 결합되면, 강선인장기(도시없음)로 상기 강선(30)을 긴장시켜 강선(30)에 프리스트레스 힘을 도입하여 암거유닛(10)을 최대한 밀착시킨다. 이때 암거유닛(10)이 최대한 밀착된 상태에서 상기 너트(41)를 최대한 더 조여 암거유닛(10)이 완전히 접합되도록 한 후 강선인장기의 인장상태를 해제하면 암거유닛(10)이 연결된다.When the culvert unit 10 adjacent to the culvert unit 10 is coupled by the bolt 30, the nut 41 and the steel wire 30 as described above, the steel wire 30 by a wire tensioner (not shown) Tension is introduced to the pre-stress force to the steel wire 30 to close the culvert unit 10 as close as possible. At this time, when the culvert unit 10 is as close as possible, tighten the nut 41 as much as possible so that the culvert unit 10 is completely bonded, and then release the tension state of the steel wire tensioner culvert unit 10 is connected.
상기와 같은 과정을 여러번 반복하여 다수개의 암거유닛(10)을 결합시키고, 강선(30)의 정착작업과 볼트결합이 완료되면 상기 설치홈(22)에 콘크리트 모르타르를 채워 정착구(31) 및 볼트(40)와 너트(41)의 결합부분이 풀려지지 않고 부식이 방지되도록 마감한다.By repeating the above process several times to combine a plurality of culvert unit 10, when the fixing operation and bolting of the steel wire 30 is completed, fill the concrete mortar in the installation groove 22, the fixing unit 31 and the bolt ( 40) and the coupling portion of the nut 41 is finished to prevent loosening and corrosion.
또한 상기 날개부(20)의 그라우팅수용부(23)에 콘크리트 모르타르를 채워 넣어 암거유닛(10)이 접합되도록 한다.In addition, the grouting unit 23 of the wing portion 20 is filled with concrete mortar so that the culvert unit 10 is joined.
상기와 같은 본 발명은 암거유닛(10)의 측면으로 돌출 형성된 날개부(20)를 통해 암거유닛(10)이 결합되기 때문에 설치홈(22)을 통해 공동구(14)의 내부로 발생되는 누수가 억제된다. 즉 암거유닛(10) 구조체의 외부에서 결합이 이루어져 결합면이나 정착구(31)가 정착되는 설치홈(22)을 통해 물이 스며드는 것을 방지할 뿐만 아니라, 암거유닛(10) 외부결합에 의한 볼트결합 및 강선(30)의 인장이 간편하여 시공속도가 상승된다.In the present invention as described above, because the culvert unit 10 is coupled through the wing portion 20 protruding to the side of the culvert unit 10 is leaked into the cavity 14 through the installation groove 22 Suppressed. That is, the coupling is made from the outside of the culvert unit 10 structure to prevent water from penetrating through the installation groove 22 in which the mating surface or the fixing unit 31 is fixed, as well as the bolt coupling by the culvert unit 10 external coupling. And the tension of the steel wire 30 is easy to increase the construction speed.
또한 프리스트레스가 도입되는 강선(30) 및 볼트(40)와 너트(41)의 결합에 의해 암거유닛(10)이 결합되기 때문에 결합되는 암거유닛(10)간의 접합력이 상승되어 부등침하에 의한 저항력이 상승된다. In addition, since the culvert unit 10 is coupled by the combination of the steel wire 30 and the bolt 40 and the nut 41 into which the prestress is introduced, the bonding force between the culvert units 10 to be coupled is increased, so that the resistance due to uneven settlement is increased. Is raised.
또한 암거유닛(10)의 측벽(13) 외부에 날개부(20)가 형성되어 있어, 상기 날개부가 되메우기 토사에 대한 종방향으로의 전단키 역할을 하여 토사의 교란에도 저항할 수 있다.In addition, the wing portion 20 is formed outside the side wall 13 of the culvert unit 10, the wing portion can act as a shear key in the longitudinal direction to the backfilling soil, it can also resist soil disturbance.
본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
상기와 같은 구성 및 작용에 의해 기대할 수 있는 본 발명의 효과는, 암거유닛를 강선을 이용한 프리스트레스의 도입과 동시에 볼트결합을 해줌에 따라 암거유닛간의 접합력이 매우 상승되어 부등침하에 대한 저항력이 증가하고, 날개부에 의해 암거유닛의 외부에서 결합되는 구조로서 긴장력도입 및 볼트결합이 간편하여 시공이 용이하며 접합재료의 손실량이 감소되어 경제성이 우수하며, 날개부가 전단키 작용을 하여 토사의 교란에도 저항할 수 있는 매우 유용한 발명이다.The effect of the present invention can be expected by the configuration and action as described above, as the coupling of the culvert unit and the bolt at the same time as the introduction of the pre-stress using a steel wire, the bonding force between the culvert unit is very increased, the resistance to inequality is increased, It is a structure that is coupled from the outside of the culvert unit by the wing part, so it is easy to install due to the easy introduction of tension force and bolting, and the loss amount of bonding material is reduced, and the economic efficiency is excellent. That is a very useful invention.
