설계일반지침 시공일반지침 유량설계 (Hydrometric design) 터파기 (Trench Construction and Terminology) 1. 유량계산 (Hydrometric equation) 한국 PEM PIPE 의유량계산은 HazenWilliams 공식을사용하여산출한다. HazenWilliams' formula is used to measure quantity of discharge. PEM PIPE 는지상에서긴길이로맞대기융착 (UTT FUSION) 할수있으므로굴토폭을줄여설치비용을절감할수있다. 또한터파기시현장여건및토질의상태를고려한후굴토폭을최소한좁게한다. ecause PEM Korea pipes can be butt fused above ground in long lengths, narrow trench widths can be used to save on installation costs. It necessitates a minimum width of open trench after due consideration of the condition of soil. Q =.V V = 0.935CR = 3.1D 2 Q = 0.53 CD 0.3 0.5 I 0.3 0.5 I 2. 손실수두계산 (oss of head by abrasion) 여기서, Q : 유량 [quantity of discharge] ( m3 /sec) : 관의단면적 [area passed by flow] ( m2 ) V : 유속 [the velocity of flow] (m/sec) C : 유속계수 [the velocity of flow factor] (PEM=1) R : 경심 [hydraulic radius] ( 원형관D/)(m) I : 동수구배 (h/) D : 관의내경 [diameter of a pipe] (m) 한국 PEM PIPE 는부식되지않고, 녹이나 Scale 이형성되지않으므로유속계수 "C" 값은경과년수에관계없이일정한값을유지한다. PEM Korea pipes do not erode and scale, and are not rusted. Therefore, the velocity of flow factor "C" is fixed. 마찰손실수두외의손실은관로의연장이길어지면매우적어지므로무시해도좋다. 마찰손실수두의계산은다음식에의한다. When extension of pipeline is getting longer, loss except friction head loss can be ignored because it becomes smaller. The friction head loss of PEM Korea pipe is determined by the following equation. 1. 굴토폭 굴토폭은파이프주위에적절히흙을채울수있어야하며, 파이프외경보다 cm정도넓은것이적당하다. 보통굴착된재료는암석이없고, 굴착기로쉽게부수어지면기초재료로서적합하게쓰여진다. Proper excavated trench width is cm wider than ouside diameter. It can be the proper foundation when there is no rocks in excavated material or excavated material can be broken by the excavator. 2. 굴토바닥 굴토바닥은단단하지않으며, 암석이없어야한다. 파이프에하중을가할수있는바위, 표석이나커다란돌들은제거되어야하며, 파이프및이음관의위아래주위에모래등의기초재료를메워놓아야한다. The trench bottom should be smooth and dry. It should also be free of any clumps of earth, large rocks or foreign materials. The foundation like sand must fill around pipes and fittings. 2 V hf = f, 133.7 f = 0.17 1.5 D 2g D C V 0.15 내압설계 (Hydrostatic design) 1. 설계압력 (Design Presssure) 여기서, hf : 마찰손실수두 [friction head loss] (m) f : 관의마찰계수 [friction factor] g : 중력가속도 [gravity acceleration] (m/sec2) c : 유속계수 [the velocity of flow factor] 관기초 PEM PIPE 는유연성이뛰어나강성관에비해다소부등침하가있는연약지반에설치하여도탄력적으로반응하여파괴되거나이탈될염려는없으나, 연약지반의경우모래또는쇄석등으로치환한후설치한다. 보통의경우관기초는다음과같이한다. PEM Korea pipes are buried utilizing flexible pipe/soil system design practices. The pipe actually gains strength from the surrounding soil allowing it to support additional loads. PEM PIPE 의설계압력은다음공식에의거산출한다. The design pressures for PEM Korea pipe are determined by the following equation. P = = 2σ t D t 2σ (SDR 1) 여기서, P : 설계압력 [design pressure] ( kg / cm2 ) σ : 설계원추응력 ( kg / cm2 ) t : 관의두께 [thickness] ( cm ) D : 관의외경 [outside diameter] ( cm ) SDR : D/t Trench Cross Section (15~cm) 되메움토 최종되메우기 ( 다짐 % 이상 ) 2. 압력에따른파이프의사용년한 (Pipe Pressure Rating) 관외경 1 차되메우기 ( 다짐 5% 이상 ) 구분 PIPE PRESSURE RTING PEM PIPE(at ) SDR 11 SDR 13.5 SDR 15.5 SDR 2 모래기초 (15cm 이상 ) GUIDEINES 2 ong Term Strength( kg / cm2 ) Safety Factor Hydrostatic Design Stress Design ife(min, years) Pressure Rating( kg / cm2 ) 설계수명 Design ife 1 개월 (one month) 1 년 (a year) 년 ( years) 1 2.0 5 11.2 1 2.0 5.9 흡입관경이큰 Siphon 배관등에있어서는진공압에대하여고려해야한다. 다음표는관종별로설계수명에따른사용가능한진공압을나타낸것이다.

The backfill offers bearing power that is strong and maintained, and economics usually dictate maximum reuse of the excavated material. The best initial backfill material is sand. The primary backfill zone should normally extend to a height equal to % of the pipe diameter. The secondary backfill should normally be 15 cm to cm above the crown of the pipe. If the pipe is below vehicular traffic, compaction should be to % to 95% Standard Proctor density, and over 5% Standard Proctor density for the others. GUIDEINES

2 GUIDEINES GUIDEINES 시공일반지침 매몰배관 (uried Pipelines) 지상배관 (Overland Pipelines) 가볍고유연성이좋은한국 PEM 관은타관과같이터파기안에서연결하는경우도있지만, 터파기의폭을줄이기위하여지면위에서길이만큼융착을하여부설할수있어설치시비용을절감할수있다. 또한최소한의굴곡반경이확보되면이음관을사용치않고도얼마든지곡선배관이가능하다. ecause PEM Korea pipes can be butt fused above ground in long lengths, narrow trench widths can be used to save on installation costs. With PEM Korea pipe, fewer fittings are required at the minimum bent radius. R = 15 x D 최소굴곡반경 R = x D 최소굴곡반경 매몰배관시하절기에는배관자체를사행식으로부설하고동절기에는될수있는한직선배관을하는것이온도변화에따른응력을제거할수있다. 융착및부설할때파이프표면이손상되지않게주의하여야한다. 지표면에서파이프에적용할수있는최대인취력은다음공식에의하여산출한다. In the summer season, it will want to "snake" for installation and "straight" in the winter season because stress as environmental temperature changes can be reduced. Care should be taken to prevent damage of the pipe when fusing or laying. The maximum tensile force is determined by the following equation. 연결부분 임시적인배관슬러리 (Slurry) 나광석의찌꺼기수송용, 매립준설용과같이유지관리가빈번히일어나는배관등노출배관을할필요가있다. 파이프를지상에노출시켜배관할경우가장중요하게고려되야할부분은내부온도와외부환경에대한파이프의적절한설계이다. 한국 PEM PIPE 는자외선으로부터보호받을수있도록자외선안정제 (UVStabilizer) 인카본블랙 (Carbon lack) 이함께콤파운딩 (Compounding) 된원료를사용하여만든파이프이므로장시간자외선을받는다해도파이프표면의산화등부식이일어나지않으며그수명또한반영구적으로설계되어있다. 그러므로노출배관시에는기타청색 (lue), 노란색 (Yellow) 관보다는검정색 (lack) 관을사용하는것이파이프의수명을연장하는데유리하다. 하지만, 이런검정색관은자외선에대한관의손상은피할수있지만태양열에의한파이프표면온도변화를심하게일으킬수있다. 태양열에의한파이프표면온도변화는내부가비어있는파이프일때최대 ~ 까지의변화를갖는다. 또한, 파이프가지표면에닿는부분과태양의직사광선을받는부분의온도변화가다르므로장시간노출시배관의비틀림을일으킬수있다. 이러한비틀림을방지하기위하여노출배관시에는반드시일정한간격을두고엥카링 (nchoring) 을해야하고, 보온덮게 (Cover) 또는흙을 cm정도덮어주는것이효과적인방법이다. 또는온도변화에의한팽창과수축으로인한파이프의변형이발생되는것을방지하기위하여배관시일정한간격을두고엥카링을해야만한다. 즉, 엥카 (nchor) 사이에관을적당히굽고만곡부분을주어수축이일어날경우는파이프가긴장되고, 팽창이일어날경우에는파이프가좀더굽을수있게설계하여배관해야한다. 이때만곡길이는아래식으로계산할수있다. Overland pipelines will be needed for slurry transport in many industries or dredge lines. The most important thing of overland pipeline is the design about internaltemperature and outsideenvironment. PEM Korea pipes have been made from compound materials including Carbon lack(uvstabilizer), so pipe does not erode and designed semipermanently. Thus, lack pipe is better than lue or Yellow pipe for long life in case of overland pipelines. lack pipe has the natural ability to withstand ultraviolet radiation, but surface temperature change may occur due to the sun's heat. Surface temperature may change to when pipe is empty. Pipeline also may twist because temperature change is different between point that pipes reach to earth's surface and point that pipes reach to sunlight. In order to prevent the twist, anchor regular distance and cover or cover soil cm. In order to prevent pipe's change due to thermal expansion/contraction, anchor regular distance. Design and install pipe deflection to relax and settle when contraction and expansion occur. ateral deflection is determined by the following equation. F = S 여기서, F : 최대인취력 [max. tensile force] ( kg ) S : 최대혀용압력 [max. application pressure] (70~105kg/ cm2적용 ) : 파이프벽의단면 [pipe wall crosssectional area] ( cm2 ) PEM 관은온도에대한수축, 팽창계수가철관이나콘크리트관보다 10 배정도크지만, 폴리에틸렌재료는점탄성이라는특성을가지고있으므로온도변화에의해발생하는응력은시간의경과에따라자연적으로이완되고조정된다. 또한, 매설관에있어서는마찰력과차단력으로온도의변화에따른파이프의이동을억제시킬수있다. PEM 관을매설시가장중요한작업은되메우기이다. 이는되메움흙의종류및상태에따라서 PIPE 의외압강도가변하기때문이다. 같은조건에서흙다짐의차이를보면잘다져진파이프와그렇치않은파이프는매우큰외압강도의차이를나타낸다. 되메움시에파이프에국부적인집중응력이발생하는것을막기위해되메움재는암석을피하고입자의크기가균일한양질토사를사용한다. 특히파이프저면에암석등이있을경우에는필히모래또는양질의토사로치환한후파이프를부설해야한다. ( 만일, 치환을실시하지않으면파이프에국부적인손상이발생하여파이프의파손을불러일으킬수도있다.) Coef.of thermal expansion/contraction as temperature changes of PEM pipe is almost 10times of iron pipe or concrete pipe, but the stress as temperature changes will relax and settle naturally because PE is viscoelastic. Movement of pipe as temperature changes can be controled by friction for buried pipelines. The most important work is backfill when PEM Korea pipe is installed because type or condition of soil can have an effect on earth pressure. There are a lot of differences between wellbackfilled and the other for earth pressure. ackfill material should be free of any clumps of earth, large rocks or foreign materials. If there are rocks below the pipe, rocks should be exchanged to sand or soil of good quality. (Pipe can be damaged by rocks.) 여기서, ΔY : 측면만곡길이 [ateral deflection] ( cm ) : nchor 간의길이 [ength of pipe between anchors] ( cm ) α: PIPE 의선팽창계수 [Coef.of thermal expansion] ( cm / cm ) ΔT : 온도변화량 [Change in temperature] ( ) 예 ) 직관상태 m 간격으로엥카 (nchor) 을설치한배관에서온도변화가 라면 ΔY 는다음과같다. ex.) If is m and ΔT is, ΔY will be as follow.

In installing, if anchor 77.5 cm, pipe may not be damaged by temperature change. ength of pipe between anchors is determined by the following equation. ε 는파이프의비틀림정도를말하며 1% 에서 5% 를적용하는데 1% 의비틀림이일어나는곳에는엥카 (nchor) 간의거리가길어지고 5% 의비틀림이생기는곳에는엥카 (nchor) 간의길이가가까워진다. 실제로 1% 이하의값을적용하기도하지만보통의경우 1% 정도의값을적용하고있다. ε is strain and usually apply 1% to 5%. In case of 1% strain, length of pipe between anchors is getting longer, and in case of 5% strain, the length is getting closer. Sometimes apply under 1% strain, but usually apply almost 1% strain. nchor 방법및종류 여기서, D : 파이프의외경 [outside diameter] ( cm ) ε: 파이프의비틀림 [strain] ( cm / cm또는 %) PIPE 관경 (Inches) PIPE 관경 (Inches) 52 0 3 2 2 1 0 2 2 1 1 1 10 2 0 SDR.5 5 C 52 C 3 C C 10 0 0 70 0 1 1 10 1 지지간격 (Inches) SDR 15.5 5 C 52 C 3 C C 10 0 0 70 0 1 1 10 1 지지간격 (Inches) PIPE 관경 (Inches) PIPE 관경 (Inches) 52 0 3 2 2 1 0 2 2 1 1 1 10 2 0 SDR 2 5 C 52 C 3 C C 10 0 0 0 1 1 10 1 10 170 지지간격 (Inches) SDR 11 5 C 52 C 3 C C 10 0 0 70 0 1 1 10 1 지지간격 (Inches) PIPE 관경 (Inches) 52 0 3 2 2 1 0 SDR 9 5 C 52 C 3 C C 5 10 15 35 0 5 55 0 5 70 지지간격 (Inches)
