Description

친환경 하수관거의 맨홀 구조{Manhole structure of eco-friendly sewer pipe}Manhole structure of eco-friendly sewer pipe}

본 발명은 하수 관거 기술 분야 중 친환경적인 하수관거의 맨홀 구조에 관한 것으로, 보다 상세하게는 하수관거에 연결 되도록 설치된 대형맨홀을 시공할 때 맨홀을 다수의 세그먼트로 분할하여 중량과 볼륨을 줄이고 이송 편의성을 향상시키며, 시공시 적층 접합하여 친환경적으로 맞춤식 조립함으로써 시공편의성도 향상시켜 안전사고의 위험을 친환경적으로 줄이고 시공 시간도 단축할 수 있도록 개선된 친환경 하수관거의 맨홀 구조에 관한 것이다. The present invention relates to an eco-friendly manhole structure of a sewer pipe in the field of sewer pipe technology. More specifically, when constructing a large manhole installed to connect to a sewer pipe, the manhole is divided into a number of segments to reduce weight and volume and improve transportation convenience. It is about an improved eco-friendly sewer pipe manhole structure that reduces the risk of safety accidents in an eco-friendly way and shortens construction time by improving construction convenience by laminating and bonding during construction and customizing and assembling in an eco-friendly manner.

일반적으로, 도로의 지하에는 상수관, 하수관, 전력 케이블, 통신 케이블 등의 각종 시설물이 많이 매설되어 있고, 이러한 각종 시설물 등은 필요에 따라 수시로 보수를 행하여야 한다. In general, many various facilities, such as water pipes, sewer pipes, power cables, and communication cables, are buried underground under roads, and these various facilities must be repaired from time to time as necessary.

따라서, 각종 시설물의 유지 보수를 위해 일정간격을 두고 맨홀이 시공되어 있다.Therefore, manholes are constructed at regular intervals for maintenance of various facilities.

그리고 맨홀 하부에는 하수 또는 우수를 하수처리장 또는 하천으로 이동시키는 이동로를 형성하는 수평관이 결합되어 연결된다.And at the bottom of the manhole, a horizontal pipe is connected to form a path for moving sewage or rainwater to a sewage treatment plant or river.

이때, 맨홀 및 수평관이 매설된 도로는 자동차의 주행 또는 사람의 통행에 따라 반복적인 하중이 작용하여 지반이 침하되고, 이와 같은 지반침하는 지면의 용도 및 상황에 따라 서로 다르게 발생되어 매우 불균일한 부등침하가 발생된다.At this time, on roads where manholes and horizontal pipes are buried, the ground subsides due to repetitive loads depending on the driving of cars or the passage of people, and this ground subsidence occurs differently depending on the use and situation of the ground and is very uneven. Differential settlement occurs.

이에 따라 맨홀과 수평관의 연결부위는 맨홀 구조물의 취약부분으로 작용하고, 수평관의 연결부위에서 균열 및 부분 파괴가 빈번히 발생된다.Accordingly, the connection area between the manhole and the horizontal pipe acts as a vulnerable part of the manhole structure, and cracks and partial destruction frequently occur at the connection area of the horizontal pipe.

나아가 수평관 연결부위의 파괴는, 해당 부분이 지반 내에 매립된다는 특성상, 하수나 우수의 유출이 심각하게 발생된 이후에나 이를 인지할 수 있으므로, 이로 인한 피해는 확대되는 경향이 있다.Furthermore, because the destruction of the horizontal pipe connection part can be recognized only after a serious outflow of sewage or rainwater has occurred due to the nature of the part being buried in the ground, the resulting damage tends to be expanded.

이에 따라 맨홀과 수평관이 견고히 결합되면서, 수밀성이 유지되며, 시공이 용이한 맨홀구조에 대한 필요성이 있어 하기한 [선행기술문헌]과 같은 개량형 맨홀 구조를 갖는 공개특허가 개시된 바 있다.Accordingly, there is a need for a manhole structure that firmly combines the manhole and the horizontal pipe, maintains watertightness, and is easy to construct, so a published patent has been disclosed having an improved manhole structure such as the [Prior Art Document] described below.

그런데, 맨홀이 소형이 아닌 대형인 경우 맨홀몸체를 거대 원통으로 만들어 설치하는데에는 많은 한계가 있다. 즉, 설치지점으로 이송하는데에 발생하는 문제점 뿐만 아니라, 이를 들어 올려 시공할 때 드는 난점과 중량물에 의한 안전사고는 심각한 인명손상을 초래하기도 한다.However, when the manhole is large rather than small, there are many limitations in installing the manhole body by making it a huge cylinder. In other words, not only are there problems arising in transporting it to the installation point, but also difficulties in lifting and constructing it and safety accidents caused by heavy objects can result in serious casualties.

따라서, 안전사고와 심각한 인명손상을 초래하지 아니하는 친환경적인 하수관거 맨홀에 관련된 기술의 개발 필요가 있다. Therefore, there is a need to develop technology related to environmentally friendly sewer manholes that do not cause safety accidents or serious casualties.

In the manhole structure; The first, second, and third semicircular watertight reinsertion grooves (102, 112, and 122) are recessed on surfaces where the first manhole segment (100), second manhole segment (110), and third manhole segment (120) are in contact with each other; The ring-shaped watertight material 130 is inserted into the first, second, and third watertight reinsertion grooves (102, 112, and 122) so that each segment engages with each other to seal the contact surfaces of the first, second, and third manhole segments (100, 110, and 120); Mortar anchor grooves 140 are formed at intervals from the first, second, and third watertight reinsertion grooves 102, 112, and 122, respectively; A mortar injection hole 150 communicating with the mortar anchor groove 140 is formed on a portion of the circumference of the first, second, and third manhole segments (100, 110, and 120), and the first, second, and third manhole segments (100, 110, and 120) are stacked. It provides a manhole structure for an eco-friendly sewer pipe, which is configured to inject mortar into the mortar injection hole 150 in one state so that the mortar is filled, hardened, and anchored in the mortar anchor groove 140 and the mortar injection hole 150.

이때, 상기 제3맨홀세그먼트(120)의 상부에는 뚜껑체(160)가 조립되되, 상기 뚜껑체(160)는 외경이 상기 제3맨홀세그먼트(120)의 외경보다 단차(T)만큼 작게 형성되어 맨홀 내부에서 발생되는 유해가스가 자동으로 배출될 수 있게 구성되며; 상기 뚜껑체(160)의 둘레에는 적어도 하나 이상의 반원형 방출홀(162)이 형성되고; 상기 반원형 방출홀(162)에는 뚜껑체(160)를 원중심방향으로 관통한 뒤 저면으로 수직 관통한 배출유로(164)가 연결된 것에도 그 특징이 있다.At this time, a lid 160 is assembled on the upper part of the third manhole segment 120, and the lid 160 has an outer diameter smaller than the outer diameter of the third manhole segment 120 by the step T. It is configured to automatically discharge harmful gases generated inside the manhole; At least one semicircular discharge hole 162 is formed around the lid 160; The semicircular discharge hole 162 is also characterized by being connected to a discharge passage 164 that penetrates the lid body 160 in the circular center direction and then vertically penetrates the bottom.

However, this is not intended to limit the embodiments according to the concept of the present invention to a specific disclosed form, and should be understood to include all changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.

본 발명에 따른 친환경 하수관거의 맨홀 구조는 대형맨홀의 시공시 활용된다.The manhole structure of the eco-friendly sewer pipe according to the present invention is utilized during the construction of large manholes.

즉, 대형맨홀을 다수의 세그먼트로 분할하여 상호 적층식으로 조립시공함으로써 이송편리성, 시공편의성, 안전사고의 위험감소 효과를 얻을 수 있도록 한 것이다.In other words, by dividing the large manhole into a number of segments and assembling them in a stacked manner, it is possible to obtain convenience in transportation, convenience in construction, and reduction in the risk of safety accidents.

보다 구체적으로, 도 1 내지 도 2에 도시된 바와 같이, 본 발명에 따른 맨홀은 제1맨홀세그먼트(100), 제2맨홀세그먼트(110), 제3맨홀세그먼트(120)로 이루어질 수 있다.More specifically, as shown in FIGS. 1 and 2, the manhole according to the present invention may be composed of a first manhole segment 100, a second manhole segment 110, and a third manhole segment 120.

이 경우, 본 발명에서는 3개의 세그먼트를 예시적으로 설명하였으나 대형맨홀의 크기가 더 크고 더 길 경우에는 더 많은 세그먼트로 나눌수도 있음은 물론이다.In this case, in the present invention, three segments have been described as an example, but of course, if the large manhole is larger and longer, it can be divided into more segments.

특히, 본 발명에 따른 제1,2,3맨홀세그먼트(100,110,120)들은 서로 고정하기 위해 외부에 별도의 고정부재, 이를테면 볼트나 혹은 앵커 혹은 클램프 등을 사용하지 않는 것이 특징이다.In particular, the first, second, and third manhole segments 100, 110, and 120 according to the present invention are characterized in that they do not use separate external fixing members, such as bolts, anchors, or clamps, to fix them to each other.

이들을 사용할 경우, 각 세그먼트들을 적층한 후에 다시 서로 결속하는 작업을 수행해야 하는데 이것은 또하나의 작업꺼리가 되고 고소작업에 따른 안전사고의 위험을 초래하며, 작업중 세그먼트들의 전도 위험도 있다.When using these, after stacking each segment, the work of binding them together must be performed again, which is another task and causes the risk of safety accidents due to working at heights, and there is also a risk of the segments falling over during work.

이에, 본 발명에서는 단순히 적층하는 것만으로 작업이 마무리되며, 그라운팅 방식으로 몰탈을 주입하여 자동으로 앵커링되게 하는 고정방식을 사용한다.Accordingly, in the present invention, the work is completed simply by stacking, and a fixing method is used in which mortar is injected through a grounding method and automatically anchored.

이를 위해, 상기 제1맨홀세그먼트(100), 제2맨홀세그먼트(110), 제3맨홀세그먼트(120)들이 서로 접하는 면에 각각 반원형상의 제1,2,3수밀재삽입홈(102,112,122)이 요입 형성된다.For this purpose, semicircular first, second, and third watertight reinsertion grooves 102, 112, and 122 are recessed on the surfaces where the first manhole segment 100, second manhole segment 110, and third manhole segment 120 are in contact with each other, respectively. is formed

이때, 상기 제1,2,3수밀재삽입홈(102,112,122)에는 링형상의 수밀재(130)가 각 세그먼트들이 서로 맞물도록 삽입되어 제1,2,3맨홀세그먼트(100,110,120)들의 접촉면을 완전히 씰링하게 된다.At this time, the ring-shaped watertight material 130 is inserted into the first, second, and third watertight reinsertion grooves (102, 112, and 122) so that each segment engages with each other to completely seal the contact surfaces of the first, second, and third manhole segments (100, 110, and 120). I do it.

여기에서, 상기 수밀재(130)는 BWS(Bentonite Water Stop)를 사용함이 바람직한데, 상기 BWS는 물과 접촉하였을 때 체적의 16배에 달하는 고팽창성을 지닌 소디움 벤토나이트를 압축 성형한 후 그 둘레면을 그물망사로 막아 일정치수가 되게 가공한 것이다.Here, it is preferable to use BWS (Bentonite Water Stop) as the watertight material 130, which is formed by compression molding sodium bentonite, which has a high expansion property of up to 16 times the volume when in contact with water, and then forming the surrounding surface. It is processed to a certain size by blocking it with mesh.

또한, 상기 제1,2,3수밀재삽입홈(102,112,122)과 간격을 두고 몰탈앵커홈(140)이 각각 형성된다.In addition, mortar anchor grooves 140 are formed at intervals from the first, second, and third watertight reinsertion grooves 102, 112, and 122, respectively.

상기 몰탈앵커홈(140)도 상기 제1,2,3맨홀세그먼트(100,110,120)가 원통형이므로 원주를 따라 형성된다.The mortar anchor groove 140 is also formed along the circumference because the first, second, and third manhole segments 100, 110, and 120 are cylindrical.

그리고, 상기 제1,2,3맨홀세그먼트(100,110,120)의 원둘레 일부에는 상기 몰탈앵커홈(140)과 연통되는 몰탈주입홀(150)이 형성된다.In addition, a mortar injection hole 150 communicating with the mortar anchor groove 140 is formed on a portion of the circumference of the first, second, and third manhole segments 100, 110, and 120.

따라서, 상기 제1,2,3맨홀세그먼트(100,110,120)를 적층배치한 상태에서 몰탈을 몰탈주입홀(150)에 주입시키면 몰탈이 몰탈앵커홈(140)과 몰탈주입홀(150)에 충진되고, 나중에 경화되어 굳게 되면 이것이 곧 앵커가 되어 상기 제1,2,3맨홀세그먼트(100,110,120)들을 견고하게 결속하는 효과를 갖게 된다.Therefore, when mortar is injected into the mortar injection hole 150 in a state in which the first, second, and third manhole segments 100, 110, and 120 are stacked, the mortar is filled into the mortar anchor groove 140 and the mortar injection hole 150, When it hardens later, it becomes an anchor and has the effect of firmly binding the first, second, and third manhole segments (100, 110, and 120).

이때, 앵커링 효과를 극대화시키기 위해 상기 몰탈주입홀(150)과 몰탈앵커홈(140)에 철근을 몇가닥 넣은 후에 몰탈을 부으면 더욱 좋다.At this time, in order to maximize the anchoring effect, it is better to pour mortar after inserting a few reinforcing bars into the mortar injection hole 150 and the mortar anchor groove 140.

아울러, 상기 몰탈은 단순한 시멘트-모래 혼합물이 아니라, 혼화성과 시멘트 중성화 방지 효과를 가져 장수명화가 가능하고, 물에 대한 저항성이 높은 특수 성분으로 구현된다.In addition, the mortar is not a simple cement-sand mixture, but is made of a special ingredient that has miscibility and cement neutralization prevention effects, enables long life, and has high resistance to water.

이를 위해, 본 발명에 따른 몰탈은 물 100중량부에 포틀랜드 시멘트 35중량부, 모래 25중량부, 편백유 5.5중량부, 키실렌설폰산나트륨 5중량부, 산화세륨 분말 4.5중량부, 디메틸아크릴아마이드 8.5중량부, 2-페닐이미다졸 2.5중량부, 수용성 아크릴수지 3.5중량부, 나트륨-시트레이트(Na3C6H5O7)와 황산제1철(FeSO4.7H2O)이 2:1의 중량비로 혼합된 혼합물 8.5중량부를 혼합사용한다.For this purpose, the mortar according to the present invention contains 35 parts by weight of Portland cement, 25 parts by weight of sand, 5.5 parts by weight of cypress oil, 5 parts by weight of sodium xylene sulfonate, 4.5 parts by weight of cerium oxide powder, and dimethyl acrylamide for 100 parts by weight of water. 8.5 parts by weight, 2.5 parts by weight of 2-phenylimidazole, 3.5 parts by weight of water-soluble acrylic resin, sodium-citrate (Na 3 C 6 H 5 O 7 ) and ferrous sulfate (FeSO 4.7H 2 O). : Use 8.5 parts by weight of the mixture mixed at a weight ratio of 1.

이때, 포틀랜드 시멘트는 속경성을 위해 사용된다.At this time, Portland cement is used for rapid hardening.

이 경우, 편백유는 편백나무에서 추출한 오일로 몰탈의 흐름성을 좋게 하여 깊숙이까지 침투하는 특성을 강화시킨다.In this case, cypress oil is an oil extracted from the cypress tree that improves the flowability of the mortar and enhances its ability to penetrate deep.

그리고, 키실렌설폰산나트륨은 성분간 혼화성을 높여 바인딩 안정성을 강화시키고 앵커링 능력을 향상시키며 플러핑을 방지한다. In addition, sodium xylene sulfonate increases the miscibility between components, strengthens binding stability, improves anchoring ability, and prevents fluffing.

또한, 산화세륨 분말은 금속산화물로서 마찰저항을 높여 계면간 층분리 억제력을 증진시키고, 앵커링성을 강화시킨다.In addition, cerium oxide powder is a metal oxide that increases frictional resistance, improves interfacial layer separation inhibition, and strengthens anchoring properties.

뿐만 아니라, 디메틸아크릴아마이드는 몰탈의 유동성과 흐름성을 증대시키면서 수축방지를 통해 균열을 억제하며, 지수 저항성이 크다.In addition, dimethylacrylamide increases the fluidity and flowability of mortar, suppresses cracking by preventing shrinkage, and has high water resistance.

또한, 2-페닐이미다졸은 몰탈의 건조수축률을 적게 하여 앵커의 변형을 막고 내크랙성을 증대시킨다. In addition, 2-phenylimidazole reduces the drying shrinkage rate of the mortar, prevents deformation of the anchor, and increases crack resistance.

아울러, 수용성 아크릴수지는 교합성을 높여 성분들의 앵커링 효과를 강화시키며 혼화성을 높이고 점성을 증대시켜 흐름성을 증대시키기 위해 첨가된다.In addition, water-soluble acrylic resin is added to increase occlusion, strengthen the anchoring effect of ingredients, increase miscibility, and increase viscosity to increase flowability.

마지막으로, 나트륨-시트레이트(Na3C6H5O7)는 방수 착체 형성을 위해 첨가되고, 황산제1철(FeSO4.7H2O)은 별도로 pH조절제를 첨가하지 않고도 철-시트레이트 킬레이트 화합물을 생성하여 콘크리트의 중성화을 막을 수 있다.Lastly, sodium-citrate (Na 3 C 6 H 5 O 7 ) is added to form a waterproof complex, and ferrous sulfate (FeSO 4.7H 2 O) is added to iron-citrate without adding a separate pH adjuster. Neutralization of concrete can be prevented by creating chelating compounds.

한편, 상기 제3맨홀세그먼트(120)의 상부에는 뚜껑체(160)가 조립되는데, 상기 뚜껑체(160)는 외경이 상기 제3맨홀세그먼트(120)의 외경보다 단차(T)만큼 작게 형성되어 맨홀 내부에서 발생되는 유해가스가 자동으로 배출될 수 있게 구성되어 작업자가 투입될 때 가스중독을 일으키지 않도록 구성된다.Meanwhile, a lid 160 is assembled on the upper part of the third manhole segment 120, and the lid 160 has an outer diameter smaller than the outer diameter of the third manhole segment 120 by the step T. It is configured so that harmful gases generated inside the manhole can be automatically discharged to prevent gas poisoning when workers enter the system.

이를 위해, 상기 뚜껑체(160)의 둘레에는 적어도 하나 이상의 반원형 방출홀(162)이 형성되고, 상기 반원형 방출홀(162)에는 뚜껑체(160)를 원중심방향으로 관통한 뒤 저면으로 수직 관통한 배출유로(164)가 연결된다.For this purpose, at least one semicircular discharge hole 162 is formed around the lid 160, and the semicircular discharge hole 162 penetrates the lid 160 in the direction of the circle center and then penetrates vertically to the bottom. One discharge passage 164 is connected.

따라서, 뚜껑체(160)를 닫아도 이 배출유로(164)를 통해 유해가스가 방출홀(162)로 배출되는데 무리가 없다.Therefore, even if the lid 160 is closed, there is no problem in discharging the harmful gas into the discharge hole 162 through the discharge passage 164.

이렇게 함으로써 안전사고도 예방할 수 있다.By doing this, safety accidents can also be prevented.
