1. Kuyera uye kubatanidzwa
Nyatsotevedzera mamakisi ari mudhirowa yekuvaka yekumisikidza, zvinoenderana nebenchmark mapoinzi uye mareferensi ekukwirira anounzwa neanogara maneja injinjiniya, shandisa mwero kuburitsa, uye uipe kune anogara maneja injinjini kuti aongororwe.
2. Kuchera gomba renheyo
Gomba renheyo richacherwa zvakanyatsoenderana nekukwirira uye zviyero zvejometri zvinodiwa nekugadzirwa, uye chigadziko chichacheneswa uye chigadziriswe mushure mekuchera.
3. Kudira nheyo
(1) Nyatsotevedzera zvakatemwa zvemukati zvakatsanangurwa mudhizaini yedhizaini uye nzira yekusungira inotsanangurwa mune tekinoroji yakatarwa, ita kusungira uye kuisirwa masimbi ekutanga simbi, uye simbisa iyo neanogara anoona injiniya.
(2) Nheyo dzakaiswa zvikamu zvinofanirwa kunge zvichipisa-dip galvanized.
(3) Kudururwa kwekongiri kunofanirwa kunyatso mutswa zvakaenzana zvichienderana nechiyero chemidziyo, yakadururwa muzvidimbu zvakachinjika, uye ukobvu hwekudedera kusinga pfuure 45cm kudzivirira kupatsanurwa pakati pematanho maviri.
(4) Kongiri inodururwa kaviri, kudira kwekutanga kunenge 20cm pamusoro pechitsiko chesimbi, mushure mekunge kongiri yatanga kusimba, scum inobviswa, uye mabhoti akaiswa akanyatsogadziriswa, ipapo chikamu chakasara chekrete chinodururwa kuti chive nechokwadi chenheyo Iko kukanganisa kwekona kwekuiswa kweflange hakusi kupfuura 1%.
