Description

조립식 암거 {Precast culvert}Prefab Culvert {Precast culvert}

본 발명은 하수구, 전력구, 통신구, 공동구 등을 형성하는 조립식 암거에 관한 것이다.The present invention relates to a prefabricated culvert forming a sewer, an electric power tool, a communication tool, a cavity.

일반적으로, 도시의 지하 공간에는 배출되는 하수를 하수종말처리장으로 유도하거나 가정으로 전력 및 통신 서비스를 제공하는 케이블을 부설하기 위한 하수구, 전력구, 통신구, 공동구 등이 설치되는데, 도로 등을 파서 매설로를 형성하고, 일정한 장소에서 제작된 프리캐스트 콘크리트인 조립식 단위 암거를 서로 연결하여 하수구, 전력구, 통신구 공동구 등을 설치한다.In general, in the underground space of the city, sewers, electric power stations, communication districts, joint districts, etc. are installed to induce discharged sewage to sewage treatment plants or to lay cables providing electric power and communication services to homes. A buried road is formed, and the prefabricated unit culverts, which are manufactured in a certain place, are connected to each other to install sewers, power ports, and communication wards.

이와 같이 하수구, 전력구, 통신구, 공동구 등의 설치에 사용되는 단위 암거는 통상 사각형으로 형성되는데, 내측에 형성된 공간은 케이블 부설이나 하수를 처리하기 위한 수로로 사용된다. 또한, 단위 암거의 양측 단부면에는 돌출부와 이에대응하는 요홈이 형성되어 있으며, 모서리에는 각각의 단위 암거를 결합하는 강선이 삽입되는 관통홀이 형성되어 있다.As such, the unit culverts used for installation of sewers, power ports, communication ports, and cavity ports are generally formed in a rectangular shape, and the space formed inside is used as a channel for treating cable laying or sewage. In addition, protrusions and corresponding grooves are formed on both end surfaces of the unit culverts, and through holes are formed in the corners through which steel wires joining the unit culverts are inserted.

따라서, 도로 등에 형성된 매설로에 일측 단위 암거를 안착시키고, 이 단위 암거의 일측 단면부에 형성된 요홈에 타측 단위 암거의 단면부에 형성된 돌출부를 삽입하는 방식으로 다수의 단위 암거를 연결하고, 각각의 단위 암거의 모서리에 형성된 관통홀에 강선을 삽입하여 단위 암거를 서로 결합한 뒤, 누수를 방지하기 위하여 단위 암거의 결합부위에 지수재를 도포하면 하수구, 전력구, 통신구, 공동구 등이 설치 완료된다.Therefore, a plurality of unit culverts are connected by placing one unit culvert on a buried road formed in a road or the like, and inserting protrusions formed in the end portion of the other unit culvert into grooves formed in one end surface of the unit culvert. Insert the steel wires into the through-holes formed at the corners of the unit culverts, and then combine the unit culverts with each other, and apply the water repellent to the joints of the unit culverts to prevent leakage. .

그러나, 이와 같이 강선을 통해 각각의 단위 암거를 서로 결합하여 하수구, 전력구, 통신구, 공동구 등을 형성하는 종래의 조립식 암거는 시간의 경과에 따라 강선이 인장되면 단위 암거간의 결합력이 저하된다는 문제점이 있다. 즉, 결합력의 저하로 단위 암거간에 툼새가 형성되어 누수가 발생할 수 있다는 문제점이 있다.However, in the conventional prefabricated culvert that combines the unit culverts with each other through steel wires to form sewers, electric power holes, communication ports, and cavity holes, when the steel wire is tensioned over time, the coupling force between the unit culverts decreases. There is this. That is, there is a problem in that the tombs are formed between the unit culverts due to the decrease in the bonding force, which can cause leakage.

또한, 단위 암거를 서로 연결하기 위해서는 단면부에 형성된 요홈과 돌출부를 일치시켜야 하는데, 일반적으로 단위 암거는 통공에 작업자가 들어가 작업을 수행할 수 있을 정도로 그 크기가 크고, 무거우므로 요홈에 돌출부를 일치시키는 작업이 용이하지 못하다는 문제점이 있다.In addition, in order to connect the unit culverts with each other, the grooves and protrusions formed in the cross-sections must be matched. Generally, the unit culverts are large and heavy enough to allow a worker to enter a through hole and perform a work. There is a problem that the matching operation is not easy.

이에 본 발명은 상기와 같은 문제점을 해소하기 위한 것으로, 단위 암거를 서로 용이하게 결합할 수 있으며, 아울러 결합재의 접착 강도가 뛰어나 단위 암거간에 형성되는 틈새로 인한 누수를 방지할 수 있는 조립식 암거에 대한 제조 및 연결 기술의 제공을 목적으로 한다.Accordingly, the present invention is to solve the above problems, the unit culvert can be easily combined with each other, and also the adhesive strength of the binder is excellent for the prefabricated culvert that can prevent leakage due to the gap formed between the unit culvert The purpose is to provide manufacturing and connection technology.

이 경우에는 돌출부가 요부에 삽입된 다음 단위 암거의 하중에 의하여 결합되지 않는 단부가 수직으로 기울어지는 것과, 이로 인하여 틈새가 벌어지는 일이 없도록 결합핀 홈(12,12')에 결합핀(P)를 삽입 고정할 수 있다.In this case, the protrusions are inserted into the recesses, and then the end portions which are not joined by the load of the unit culverts are inclined vertically, and thus the coupling pins P are inserted into the coupling pin grooves 12 and 12 'so that there is no gap therebetween. Can be inserted and fixed.

도 3는 단위 암거가 결합된 상태를 나타내는 단면도로, 돌출부가 요부에 삽입된 단위 암거(10,10')의 결합핀 홈(12,12')에 결합핀(P)이 삽입 고정되어 있다.3 is a cross-sectional view showing a state in which the unit culvert is coupled, the coupling pin (P) is inserted into the coupling pin grooves (12, 12 ') of the unit culvert (10, 10') in which the protrusion is inserted into the recess.

또한, 요부 상면 단부는 돌출부 양측 면의 외벽에 형성한 단차는 점선으로 표시된 홈(13,14)에 연결되어 있어, 요부 상면의 단부에 양생 기간이 짧고 접착 강도 및 방수 성능이 우수한 폴리머 몰타르나 페이스트를 타설하면, 요부에 삽입된 돌출부 양측 면의 외벽에 수직 방향으로 형성된 홈(13,14)을 따라 몰타르나 페이스트가 삽입되어 상면과 측면의 틈새가 완전히 밀봉이 된다.In addition, a step formed in the outer wall of the both sides of the protrusion is connected to the grooves 13 and 14 indicated by the dotted lines, so that the upper end of the recess is short in the curing period and has excellent adhesive strength and waterproof performance. When pouring, the mortar or paste is inserted along the grooves 13 and 14 formed in the vertical direction on the outer walls of both sides of the protrusions inserted into the recesses, so that the gap between the upper surface and the side is completely sealed.

한편, 돌출부 저면 단부의 단차(15)에 의해 요부와의 접촉면에 생성된 홈도 상기 폴리머 몰타르나 페이스트를 타설함에 의해, 접촉면의 틈새가 밀봉된다.On the other hand, the groove | channel created in the contact surface with the recessed part by the step | step 15 of the bottom part of a protrusion part also places the said polymer mortar and paste, and the clearance gap of a contact surface is sealed.

상기와 같이 본 발명은, 각각의 단위 암거의 돌출부와 요부를 테이퍼지게 형성하고, 돌출부와 요부의 모든 접합면에 폴리머 몰타르나 페이스트를 타설할 수 있는 홈을 설치함으로써, 단위 암거를 서로 용이하게 결합할 수 있으며, 아울러 단위암거 간에 형성된 틈새로 인한 누수를 방지할 수 있다.As described above, in the present invention, the protrusions and the recesses of the respective unit culverts are formed to be tapered, and the unit culverts are easily coupled to each other by providing grooves for pouring polymer mortar or paste into all the joint surfaces of the protrusions and the recesses.
