Ifishi ya Bollard

Gutesha imigabane ukurikije ishingiro ryibirundo, hanyuma ushushanye arc uruziga, hanyuma ucukure intoki kugirango ucukure umwobo, kugirango ugabanye umwanya wa crouse, kugirango ugabanye umwanya wa crouse, kugirango ikipe yapimwe ikapimwa kandi yatunguye. Ingingo zo hagati ni ihuriro, hamwe na horticaltity hamwe numwanya utambitse wa casing ugomba gukosorwa numurongo inyundo. Igipimo ntarengwa kigomba kurenza 1%, kandi gutandukana ntibigomba kurenza 50Muram. Mugihe ushyingura case, ahantu hazengurutse bigomba kubazwa nubutaka buhemutse, kandi bihujwe nibisanzwe mubice. Diameter yimbere ya casing igomba kuba imaze kugaruka. Igomba kuba 20-40cm nini kuruta dilemetero, kandi ubujyakuzimu rusange ni 200-400cm. Mugihe ushyingura case, ni 30cm hejuru yubutaka karemano, kandi hafungurwaga hejuru hejuru, humura umwobo. Mubihe byihariye, ubujyakuzimu bwa casing bushobora kwiyongera, kandi uburemere bwihariye bwicyondo birashobora kwiyongera (icyondo gishobora gusukwa mu ibumba), kandi ingaruka zirashobora gutinda. Muburyo bukwiye urwego rwamazi muri casing. Niba inkombe yumuyoboro urinda ihuye namazi, hashobora kuzura ibumba kugirango ushimangire umuyoboro urinda. Gutangirwa gukabije no kwimurwa bigomba gukorerwa no kongera kwirinda isasu; Niba urukuta rwumwobo rwakubiswe, rushobora gusubirwamo mu ibumba cyangwa icyatsi kibisi (ifu ya mud) kugirango tugabanye kugirango wongere umubare w'ibyondo; Ikamyo ishyinguwe, igomba gukoreshwa umurongo winyundo n'umutegetsi wibiti, bipima intera uhereye ku nkombe ya crouse ku cyerekezo cya cross mu cyerekezo cyambukiranya (cyangwa mu cyerekezo cyiza kandi butambitse. Gutandukana, gutandukana ntibigomba kuba birenze 5Mi. Abarinzi bashyingurwa hafi y'umunwa w'Abazamu (Yashyinguwe mu cyerekezo cyambukiranya kandi ibimenyetso bine), kugira ngo umukoresha ane ashushanyije), kugira ngo uyikoresha kandi umugenzuzi mwiza ushobora gukoresha uburyo bwambukiranya ikirundo.
