본 고안은 제작이 용이하고, 특히 양생시 균열을 최소화하면서 경량화 할 수 있는 콘크리트 맨홀에 관한 것이다.The present invention is easy to manufacture, and particularly relates to a concrete manhole that can be lightweight while minimizing cracks during curing.

종래 맨홀은 다양한 종류의 것이 널리 사용되어 왔으나, 이들은 단순히 시공할 장소에서 땅을 파고 그 안에 거푸집을 제작하여 그 공간에 콘크리트 혼합물을 주입하여 타설하는 것이므로 거푸집 자재와 콘크리트 믹서등의 장비를 일일이 시공 장소까지 운반해야 하며 타설후 거푸집 제거 작업이 필연적으로 수반되는 등 시공이 매우 번거로울뿐 아니라, 이들 장비가 도로등을 점유함에 따라 교통체증을 심화시키게 되며, 균질의 맨홀 시공이 곤란하게 되는등 많은 폐단이 있었다.Conventionally, manholes have been widely used in various types, but they are simply digging the ground in the place to be constructed, and making the formwork therein and injecting the concrete mixture into the space so that equipment such as formwork materials and concrete mixers are installed one by one. The construction is very cumbersome, as it is necessary to remove the formwork after pouring, and this increases the traffic congestion as these equipment occupy the roads, and makes it difficult to install homogeneous manholes. there was.

또한 원통형 또는 사각통형으로 제작하여 시공시에는 매설 작업만을 행하는 방법도 사용되고 있으나, 이 경우에도 맨홀의 벽면이 균일한 두께로 되어 있기 때문에 양생후 미세한 클랙이 형성하게 되고, 소정의 강도 유지를 위해 그 두께가 필연적으로 두껍게 되어 콘크리트 자재의 소요량이 많아지고, 중량화되어 운반 및 취급이 곤란하게 되며, 이에 따라 시공이 난이하게되고, 맨홀 하부 양측에 하수도관을 연결함에 있어서는 단순히 맨홀 벽면에 천공된 연결공에 하수도관을 일치시키고 시멘트 몰타르로써 접합하는 것이므로 하수도관 접속부의 강도가 약하게 되어 시공후 그 접속부가 이완되거나 결렬되어 하수의 누수 염려가 있었다.In addition, a method of manufacturing a cylindrical or rectangular cylinder and performing only buried work is also used. However, even in this case, since the wall of the manhole has a uniform thickness, fine cracks are formed after curing, so as to maintain a predetermined strength. The thickness is inevitably thick, which increases the amount of concrete required, increases weight, making transportation and handling difficult, thus making construction difficult and simply connecting the sewer pipes to both sides of the lower manhole. Since the sewage pipes were matched to the ball and joined with cement mortar, the strength of the sewer pipe connection was weakened.

따라서 본고안은 이러한 종래의 제반 폐단을 해소하기 위하여 소정의 강도를 유지하면서도 양생에서 클랙의 형성을 방지하고, 경향화 할 수있으며, 원심력에 의한 제작이 가능하여 그 제작이 매우 용이하게 되고, 하수도관을 견고하면서도 그 상대 각도를 임의의 각도로 연결할수 있는 콘크리트맨홀을 제공하려는 것으로 이를 첨부도면에 따라서 상세히 설명하면 다음과 같다.Therefore, this paper can prevent and tend to form cracks in curing while maintaining a certain strength in order to solve such conventional waste ends, and it is possible to manufacture by centrifugal force, making the production very easy, and It is intended to provide a concrete manhole that can be connected to the relative angle at an arbitrary angle while the pipe is solid, which will be described in detail according to the accompanying drawings.

도시한 바와같이, 상단부에는 맨홀 뚜껑(2)이 끼워지는 걸림단턱(3)이 형성된 원통형 맨홀본체(1)의 주벽에 다수의 요홈(4)을 형성하며, 하단부 양측에는 외측으로 확개되는 테이퍼상의 하수도관 삽입공(6)을 보유하는 하수도관 연결관부(5)를 일체로 형성하고, 연결관부(5)의 내부 중간에는 정지돌기(7)를 돌출 형성하여서 된것이다.As shown in the figure, a plurality of grooves 4 are formed in the circumferential wall of the cylindrical manhole body 1 in which the mandrel step 3 into which the manhole cover 2 is fitted is formed on the upper end, and both sides of the lower end are tapered. The sewer pipe connection pipe part 5 having the sewer pipe insertion hole 6 is integrally formed, and the stop protrusion 7 is protruded in the middle of the inside of the connection pipe part 5.

미설명부호 8은 맨홀본체(1)를 구성하는 콘크리트내에 매설된 철근이고, 9는 연결관부(5)에 연결되는 하수도관이다.Reference numeral 8 is a reinforcing bar embedded in the concrete constituting the manhole body (1), 9 is a sewer pipe connected to the connecting pipe portion (5).

연결관부(5)는 어느 일측을 약간 높게 하여 시공시 높은쪽이 하수유입측으로 연결되게 한다.The connecting pipe part 5 is to raise one side slightly higher so that the high side is connected to the sewage inflow side during construction.

맨홀본체(1)는 원심력에 의한 제작이 가능하여 제작이 매우 용이하게되며, 저면은 개방된 것으로 하며 시공시 바닥콘크리트(10)로 폐쇄하는 것이다.Manhole body (1) can be manufactured by centrifugal force is very easy to manufacture, the bottom is to be opened and closed by the bottom concrete 10 during construction.

시공에 있어서는, 시공위치에 땅을 파고, 바닥에 바닥콘크리트(11)를 붓고 그 위에 맨홀본체(1)를 올려 놓아서 본체(1)하단부가 바닥콘크리트(11)에 매설되게 하고, 하수도관(9)을 연결관부(5)의 삽입공(6)에 삽입한 다음 시멘트몰타르(미도시)로써 접합하는 것이다.In construction, dig the ground at the construction site, pour the bottom concrete 11 on the floor, and put the manhole body 1 on it so that the lower end of the main body 1 is embedded in the bottom concrete 11, and the sewer pipe 9 ) Is inserted into the insertion hole 6 of the connecting pipe portion 5 and then bonded with cement mortar (not shown).

여기서 맨홀본체(1)는 그주벽에 다수의 요홈(4)이 형성되어 있으므로 종래 균일 된 두께로 맨홀에 비해 강도면에서 저하되는 일이 없으면서 그 중량이 크게 경량화되어 운반 및 취급이 매우 용이하게 되는 것이다.Here, the manhole body 1 has a plurality of grooves 4 formed on the circumferential wall thereof, so that its weight is greatly reduced in weight compared to the manhole in the conventional uniform thickness, so that the weight and weight are very easy to carry and handle. will be.

즉, 요홈(4)을 균일 두께의 맨홀에서와 동등한 단면 계수를 갖도록 형성함으로써 강도면에서 저하되지 않으며, 양생시 벽면두께에 대한 온도차로 인한 미세한 클랙이 방지되면서도, 중량면에서는 그 요홈(4)에 의해 감소되는 콘 크리트 혼합물의 량만큼 경량화되는바, 실험에 따르면 1,000㎏짜리 종래 균일 두께의 맨홀과 동등한 강도를 갖도록 할 경우 250㎏까지 경량화 할수 있었다.That is, by forming the groove 4 to have a cross-sectional coefficient equivalent to that of a manhole of uniform thickness, the groove is not deteriorated in strength, and while the fine crack is prevented due to the temperature difference with respect to the wall thickness during curing, the groove 4 in terms of weight. It is reduced by the amount of concrete mixture reduced by the bar, according to the experiment was able to reduce the weight up to 250kg to have the same strength as the manhole of 1,000kg conventional uniform thickness.

하수도관(9)을 연결함에 있어서는 연결관부(5)의 삽입공(6)에 하수도관(9)을 끼우고, 시멘트몰타르(미도시)로 접합하는 것이므로 그 연결부가 견고하게 되며, 삽입공(6)이 테이퍼상이므로 제3도와 같이 좌우 상하로 기울어진 하수도관(9)도 용이하고 견고하게 연결할 수 있고, 또한 그내부에 정지돌기(7)가 돌출되어 있어 하수도관(9)의 선단이 걸리므로 확실하고 더욱 견고하게 연결되는 것이다.In connecting the sewer pipe (9), the sewer pipe (9) is inserted into the insertion hole (6) of the connecting pipe part (5), and the connection is secured by inserting the cement mortar (not shown), the insertion hole ( 6) is tapered, so that the sewer pipe 9 inclined to the left and right and up and down as shown in FIG. 3 can be easily and firmly connected, and the stop protrusion 7 protrudes therein, so that the tip of the sewer pipe 9 is It's a secure, more solid connection.

이상과 같이 본 고안에 의하면 원심력에 의해 매우 용이하게 제작할수 있으며, 강도의 저하를 수반하는 일없이 대폭적으로 경량화되어 운반 및 취급, 시공이 용이하고, 좌우 상하로 기울어진 하수도관도 견고하고 정확하게 연결할수 있는 효과가 있다.As described above, according to the present invention, it can be manufactured very easily by centrifugal force, and it is greatly reduced in weight without accompanying a decrease in strength, so that it is easy to transport, handle and construct, and the sewer pipes inclined left and right can be firmly and correctly connected It has an effect.
