Description

신축형 유공관{A PERFORATED-PIPE}Newly built Yugong Hall {A PERFORATED-PIPE}

본 발명은 신축형 유공관에 관한 것으로, 특히 나선형으로 감아서 스파이럴관 형태로 형성시킬 수 있으며, 다수의 통공이 천공된 타공부의 상측에서 덮개부를 슬라이딩 이동시켜 길이방향으로 신축동작이 가능하도록 함과 아울러, 타공부의 폭 간격을 크게 하여 신장동작시 배수성을 향상시킬 수 있으며, 덮개부와 타공부의 측단 테두리에 제1,2절곡부를 서로 상반되는 방향으로 절곡 형성시켜 길이방향 신축 간격을 조절할 수 있고, 유공관의 외측에 편조된 구조의 커버부재를 배치시켜 유공관의 시공작업시 부직포를 생략시킬 수 있으며 외부의 흙에 의해 통공의 막힘 현상을 예방할 수 있도록 그 구조가 개선된 신축형 유공관에 관한 것이다.The present invention relates to a telescopic type perforated tube, in particular, it can be spirally wound to form a spiral tube, and a plurality of through holes are slidably moved from the upper side of the perforated part to allow a telescopic operation in the longitudinal direction. In addition, it is possible to increase the width of the perforated portion to improve drainage during the stretching operation, and to form the first and second bent portions in the opposite directions to each other on the side edges of the cover portion and the perforated portion to adjust the lengthwise stretching interval. It relates to a telescopic tube having an improved structure so that a nonwoven fabric may be omitted during construction work of the perforated tube by arranging a cover member having a braided structure on the outer side of the perforated tube and to prevent clogging of the through hole by external soil. .

일반적으로, 유공관은 농지, 암반도로나 터널 또는 하천 유역 등의 매립지 또는 쓰레기 매립지의 침출수 이송관로로 사용되는데, 주로 외주면에 부직포가 덧씌워져 집수 및 배수 효과를 증대시키고 토사의 유입을 막아 관로의 막힘이 방지되도록 하며, 아스팔트도로 하부에 설치하여 아스팔트도로의 지표수 이송관으로 사용한다.In general, perforated pipes are used as leachate transfer pipes for landfills such as farmland, rock roads, tunnels or river basins, or waste landfills. Mainly, non-woven fabrics are covered on the outer circumferential surface to increase the effect of collecting and draining and blocking the inflow of sediment and blocking the pipelines. This is to be prevented and installed below the asphalt road to be used as a surface water transfer pipe for the asphalt road.

또한, 유공관은 높은 개공율과 뛰어난 내화학성을 지니고 있기 때문에 부식 및 전식에 강하여 반영구적인 사용이 가능하며 외압강도의 우수성으로 인하여 쓰레기 매립장의 침출수 및 가스 포집관의 용도로 적합하다.In addition, since the perforated pipe has a high porosity and excellent chemical resistance, it is resistant to corrosion and corrosion and can be used semi-permanently. Due to its superior external pressure strength, it is suitable for use in leachate and gas collection pipes in landfills.

이와 같은 종래의 유공관은 대부분이 합성수지관으로 형성되어 있는 것으로서, 내구성이 약하고, 열에 약하며 압축강도가 낮아 매설된 유공관이 쉽게 파손되는 문제점이 있었다.Most of these conventional perforated pipes are formed of synthetic resin pipes, and thus have a problem in that the buried perforated pipes are easily damaged due to low durability, weak heat, and low compressive strength.

이와 같이 파손된 유공관을 교체해주어야 하나 유공관을 교체하기 위한 유지보수비용과 시간이 많이 소요되는 문제점이 있어, 파손된 유공관의 유지보수가 잘 이루지지 않고 있는 실정이다.Although the damaged perforated pipe should be replaced as described above, there is a problem that maintenance and cost for replacing the perforated pipe take a lot of time, and the maintenance of the broken perforated pipe is not well performed.

기존 유공관과 관련된 종래 선행기술로는 한국 등록실용신안공보 제20-0376282호 "원통형 유공관"(등록일자 : 2005.02.07)에 개시된 바와 같이, 유체의 배출능력을 향상시키도록, 일정한 간격으로 나열된 다수개의 가로줄과 상기 가로줄의 둘레를 따라 나선형 링이 일체로 형성됨으로써, 상기 가로줄과 나선형 링이 교차하지 않는 부분에 다수개의 통공이 형성되는 것이다.Conventional prior art related to the existing perforated pipes, as disclosed in Korean Registered Utility Model Publication No. 20-0376282 "cylindrical perforated pipes" (registration date: 2005.02.07), are listed at regular intervals to improve the discharge capacity of the fluid. The horizontal line and the spiral ring are integrally formed along the circumference of the horizontal line, so that a plurality of through holes are formed in a portion where the horizontal line and the spiral ring do not intersect.

동출원인이 선출원한 바 있는 종래 선행기술로는 한국 등록특허공보 제10-978007호 "스테인리스 유공관"(등록일자 : 2010.08.19)에 개시된 바와 같이, 돌출부와 집수공이 천공된 천공부를 교호로 형성하여 플렉시블하며 시공이 용이하고, 집수공을 통해 효과적으로 지표수를 수집되게 하며, 재질을 스테인리스로 형성하여 열에 강하고 압축강도를 높게 형성시킨 스테인리스 유공관에 관한 것이다.As a conventional prior art previously filed by the same applicant, as disclosed in Korean Registered Patent Publication No. 10-978007 "Stainless Steel Perforated Pipe" (Registration Date: 2010.08.19), alternately a perforated portion in which a protrusion and a collecting hole are perforated. It relates to a stainless steel perforated tube that is flexible by forming, easy to construct, and effectively collects surface water through a collecting hole, and formed of a material made of stainless steel, resistant to heat and high in compressive strength.

그런데, 기존 유공관의 경우에는 다수의 통공이 타공된 타공부위의 간격이 고정된 간격으로 형성되어 있으므로, 운반 이송시 운반 부피가 커지게 되고, 운반 중 발생되는 외부 충격에 의해 변형될 우려가 있으며, 길이방향 신축성이 미비하여 시공성이 불량한 단점이 있다.However, in the case of the existing perforated pipe, since the gap between the perforated portions where a plurality of perforations are perforated is formed at a fixed interval, the transport volume becomes large during transport and may be deformed by an external impact generated during transport. There is a disadvantage in that workability is poor due to insufficient stretch in the longitudinal direction.

또한, 기존 유공관의 경우에는 타공부위의 간격이 좁게 형성되어 있으므로, 배수성이 원활하지 못한 단점이 있다.In addition, in the case of the existing perforated pipe, since the gap between the perforated portions is narrow, the drainage is not smooth.

또, 기존 유공관의 경우에는 입자가 고은 흙이 통공을 막아버릴 우려가 있으므로, 상기 유공관의 외주를 따라 부직포를 감싼 후에 자갈과 흙으로 덮어서 다지는 시공방법을 채택하고 있으며, 상기 부직포를 유공관의 외주에 여러번 감아야 하는 제약이 있고, 유공관에 감겨진 부직포가 풀릴 경우 입자가 고운 흙이 통공을 막아버리게 되어 유공관의 기능을 상실하게 되는 단점이 있다.In addition, in the case of the existing perforated pipe, there is a fear that the fine-grained soil may block the perforation, and thus the construction method of wrapping the nonwoven fabric with the gravel and soil after wrapping the nonwoven fabric along the periphery of the perforated pipe is adopted, and the nonwoven fabric is applied to the periphery of the perforated pipe There is a limitation in that it has to be wound several times, and when the nonwoven fabric wound around the perforated tube is released, the fine soil of the particle blocks the perforation, thereby losing the function of the perforated tube.
