Yiziphi izidingo ezijwayelekile zokwakhiwa kwama-cofferdam wenqwaba yamashidi ensimbi ngaphansi kwamabhuloho asemadolobheni?

Uyazi ukuthi hlobo luni lwenqwaba yamashidi ensimbi? Inqwaba yeshidi lensimbi iwuhlobo lwensimbi olunomlomo okhiyekayo, futhi ingxenye yalo ephambanayo ihlanganisa ipuleti eliqondile, umsele, kanye nokwakheka kuka-Z, ezinosayizi abahlukahlukene namafomu ahlanganayo. Uhlobo oluvamile yinqwaba yeshidi lensimbi yesitayela se-Larson, okuyinqwaba yeshidi lensimbi yesakhiwo evame ukusetshenziswa embonini yezokwakha. Izinzuzo zayo yilezi: amandla aphezulu, kulula ukushayela ezingqimbeni zenhlabathi eqinile; Ukwakhiwa kungenziwa emanzini ajulile, futhi uma kunesidingo, izisekelo ze-diagonal zingafakwa ukuze zenze ikheji. Ukusebenza okuhle okungangeni manzi; Ingenza izimo ezihlukahlukene zama-cofferdam njengoba kudingeka futhi ingasetshenziswa kabusha izikhathi eziningi, iyenze isetshenziswe kabanzi. Okulandelayo, ngizokwethula izidingo ezijwayelekile zokwakhiwa kwama-cofferdam wenqwaba yamashidi ensimbi ngaphansi kwamabhuloho asemadolobheni?

Izidingo zokwakha:

1. Inqwaba yamashidi ensimbi i-cofferdam ayilungele umbhede womfula onamatshe amakhulu namatshe aqinile.

2. Izakhiwo zemishini kanye nobukhulu bezinqwaba zamashidi ensimbi kufanele zihlangabezane nezidingo ezicacisiwe.

Ngaphambi kokushayela izinqwaba zamashidi ensimbi, izindawo zokulinganisa nokubuka kufanele zimiswe phezulu, ezansi nomfula, futhi nhlangothi zombili ze-cofferdam ukuze kulawulwe ukuma kwezinhlangothi ezinde nezifushane ze-cofferdam. Lapho ushayela, izinto zokuqondisa kufanele zilungiswe ukuze kuqinisekiswe indawo efanele yenqwaba yeshidi lensimbi.

Ngaphambi kokushayela, izinto ezingangeni manzi kufanele zisetshenziselwe ukusonta ama-seams we-steel sheet lock lock ukuvimbela ukuvuza kwamanzi.

5. Uhlelo lwesicelo ukuhlanganisa ukusuka phezulu kuya phansi komfula.

6. Izinqwaba zamashidi ensimbi zingacwiliswa kusetshenziswa izindlela ezinjengokushaya ngesando, ukudlidliza, nokutshuza kwamanzi, kodwa ukutshuza kwamanzi akufanelekile ukucwila obumba.

7. Ngemuva kokulungiswa noma ukushiswa, inqwaba yeshidi lensimbi kufanele ihlolwe ngokukhiya nokuhlolwa kusetshenziswa uhlobo olufanayo lwenqwaba yeshidi lensimbi. Ukuma okuhlanganyelwe kwezinqwaba zamashidi ensimbi amabili aseduze kwenqwaba yeshidi lensimbi enwetshiwe kufanele kudiyazele phezulu naphansi.

Ngesikhathi sokushayela, indawo yenqwaba kufanele ihlolwe ngaso sonke isikhathi ukuze kuqinisekiswe ukuthi ilungile futhi umzimba wenqwaba umile. Uma kungenjalo, kufanele ilungiswe ngokushesha noma ikhishwe futhi iqhutshwe futhi.
