Munyika yemakungwa nenzizi, kune hupenyu hunowanzo furatirwa asi hwakakosha - thedredg hoseyakagadzirwa neZebung. Zvakafanana negamba rakanyarara, richitamba basa rakakura mukudhirowa mapurojekiti.
Dredg hose, sezita rinokurudzira, rinonyanya kushandiswa mukudhirowa mapurojekiti. Saka, chii chinonzi dredging engineering? Dredging engineering ipurojekiti yepasi pemvura yekuchera pasi inoitwa kuchera, kuwedzera, kana kudzika miviri yemvura yakaita senzizi nemadziva. Uye dredg hose chimwe chezvishandiso zvakakosha muchirongwa ichi.
Panyaya yekuchera chiteshi,dredg hosekuita basa rinokosha. Nekuenderera mberi kwekusimudzirwa kwekutengeserana kwenyika dzakawanda, kukosha kweindasitiri yekutumira iri kuwedzera kuve yakakurumbira. Nekudaro, nekuda kwezvinhu zvakasikwa uye zviitiko zvevanhu, nzira dzemvura dzinowanzosangana nejecha, izvo zvinokanganisa kuchengetedzeka uye kugona kwekufamba kwechikepe. Panguva ino, thedredg hoseakauya zvakanaka. Inogona kutakura zvakanaka marara akacherwa, silt uye zvimwe zvinhu kunzvimbo dzakatarwa, nekudaro kuchengetedza kutsetseka kwenzira yemvura.
Dredg hosevanoitawo basa rinokosha mukuvaka nekugadzirisa chiteshi. Chiteshi chakanaka chinoda kudzika kwemvura yakakwana uye mvura yakafara kusangana nekumisikidza uye kurodha / kuburitsa zvinodiwa zvemidziyo mikuru. Nokushandisadredg hose, iyo sediment iri pasi pechiteshi inogona kucheneswa kuti ione kuti kudzika kwemvura uye nzvimbo yechiteshi inosangana nezvinodiwa. Zvichakadaro, kudhirowa nguva dzose uye kugadzirisa zvakare kunogona kuwedzera hupenyu hwesevhisi yechiteshi uye kugadzirisa kushanda kwayo.
Pamusoro pe,dredg hosezvakare uve nemashandisirwo akanaka mukutonga kwenzizi uye kuchengetedza kwezvakatipoteredza. Kune dzimwe nzizi dzakasvibiswa, dredg hose inogona kuchenesa sediment yakasvibiswa pazasi perwizi, ichivandudza kunaka kwemvura uye nharaunda yerukova. Zvichakadaro, mumapurojekiti ekudzora mafashama,dredg hoseinogona kubatsira kukudza migero yenzizi, kuwedzera simba remafashamo, uye kuderedza njodzi yemafashamo.
Padanho rehunyanzvi,Zebung'sdredg hosevari kugara vachivandudza uye vachivandudza. Yakagadzirwa nepamusoro-simba uye inodzivirira marara, kuve nechokwadi chekushanda kwenguva refu yakagadzikana munzvimbo dzakaoma dzepasi pemvura. Panguva imwecheteyo, tekinoroji yekubatanidza yepamberi uye yekuisa chisimbiso kuita inogonesa dredg hose kumirisana nekumanikidza kwakanyanya uye kuyerera, kuvandudza dredging kunyatsoita.
Thedredg hoseyakagadzirwa neZebungrave chishandiso chakakosha mumapurojekiti epasirese ekuchera, kuita basa risingadzokerike munzvimbo dzakadai senzira yemvura, kuvaka chiteshi, kutonga kwenzizi, uye kuchengetedza kwezvakatipoteredza.
