Uhlobo lwenqwaba yeshidi lentsimbi kunye nokusetyenziswa kwayo

Inqwaba yeshiti yentsimbiluhlobo lwentsimbi eluhlaza ephinda isetyenziswe enezibonelelo ezikhethekileyo zokuqina okuphezulu, ubunzima obulula, ukumisa amanzi kakuhle, ukuqina okuqinileyo, ukusebenza kakuhle kokwakha kunye nendawo encinci. Inkxaso yenqwaba yeshiti yentsimbi luhlobo lwendlela yokuxhasa esebenzisa oomatshini ukuqhuba iintlobo ezithile zeenqwaba zeshiti zentsimbi emhlabeni ukuze zenze udonga oluqhubekayo olungaphantsi komhlaba njengesakhiwo somngxuma wesiseko. Iinqwaba zeshiti zentsimbi ziimveliso ezenziwe kwangaphambili ezinokuthuthwa ngqo kwindawo ukuze zakhiwe ngoko nangoko, ezibonakaliswa yisantya sokwakha esikhawulezayo. Iinqwaba zeshiti zentsimbi zinokutsalwa kwaye zisetyenziswe kwakhona, zinokuphinda zisetyenziswe okuluhlaza.

iinqwaba zamaphephazahlulwe kakhulu zibe ziintlobo ezintandathu ngokweentlobo ezahlukeneyo zamacandelo:Iinqwaba zephepha lentsimbi yohlobo lwe-U, Iinqwaba zesinyithi zentsimbi zohlobo lwe-Z, iinqwaba zeeshiti zentsimbi ezithe tye, iinqwaba zeeshiti zentsimbi zohlobo lwe-H, iinqwaba zeeshiti zentsimbi zohlobo lwepayipi kunye neenqwaba zeeshiti zentsimbi zohlobo lwe-AS. Ngexesha lenkqubo yokwakha, kuyimfuneko ukukhetha iintlobo ezahlukeneyo zeenqwaba zeeshiti zentsimbi ngokweemeko zeprojekthi kunye neempawu zolawulo lweendleko.

 

Inqwaba yeSheet yeMilo ye-U
Inqwaba yeshiti yentsimbi yaseLarsenluhlobo oluqhelekileyo lwenqwaba yeshiti yentsimbi, imo yayo yecandelo ibonisa imilo "U", equlathe ipleyiti ende ebhityileyo kunye neepleyiti ezimbini ezilinganayo.

Iingenelo: Iinqwaba zesinyithi ezimile okwe-U ziyafumaneka kwiindidi ezahlukeneyo zeenkcukacha, ukuze kukhethwe icandelo elinqamlezileyo nelingabizi kakhulu ngokwemeko yokwenyani yeprojekthi ukuze kuphuculwe uyilo lobunjineli kwaye kuncitshiswe iindleko zokwakha; kwaye icandelo elinqamlezileyo elimile okwe-U lizinzile ngokwemilo, akukho lula ukulitshintsha, kwaye linomthamo onamandla wokuthwala umthwalo, onokumelana nemithwalo emikhulu ethe tye nethe nkqo, kwaye lifanelekile kwiiprojekthi zemigodi yesiseko esinzulu kunye ne-river cofferdams.

Okwangoku, ngenxa yemilo yalo ekhethekileyo, ulwakhiwo lolwandiso lwe-splicing lunzima kwaye ububanzi bokusetyenziswa kwalo buncinci.

Inqwaba yeSheet Z
Inqwaba ye-Z-Sheet lolunye uhlobo oluqhelekileyo lwenqwaba yeshiti yentsimbi. Icandelo layo likwimo ye-"Z", equlathe amaphepha amabini ahambelanayo kunye nephepha elinye elidibanisayo elide.

Iingenelo: Iingqumba zentsimbi zecandelo le-Z zinokwandiswa ngokuzidibanisa, ezifanelekileyo kwiiprojekthi ezifuna ubude obude; isakhiwo sincinci, sinokuqina kakuhle kwamanzi kunye nokumelana nokuvuza kwamanzi, kwaye sibonakala ngakumbi ekuxhathiseni ukugoba kunye nomthamo wokuthwala, ezifanelekileyo kwiiprojekthi ezinobunzulu obukhulu bokumba, iileya zomhlaba eziqinileyo, okanye iiprojekthi ezifuna ukumelana noxinzelelo olukhulu lwamanzi. Iingxaki: Umthamo wokuthwala wengqumba yentsimbi yecandelo le-Z ubuthathaka, kwaye kulula ukuwohloka xa udibana nemithwalo emikhulu. Njengoko iziqwenga zayo zisengozini yokuvuza kwamanzi, kufuneka unyango olongezelelweyo lokuqinisa.

Inqwaba yePhepha le-Engile yasekunene
Inqwaba yesinyithi ye-engile yasekunene luhlobo lwenqwaba yesinyithi yentsimbi enesakhiwo se-engile yasekunene kwicandelo. Idla ngokuba nomxube wecandelo ezimbini zohlobo lwe-L okanye uhlobo lwe-T, ezinokufikelela kubunzulu obukhulu bokumba kunye nokumelana okunamandla kokugoba kwiimeko ezithile ezikhethekileyo. Iingenelo: Iinqwaba zesinyithi zentsimbi ezinecandelo le-engile yasekunene zinokuxhathisa okunamandla kokugoba kwaye aziguquguquki lula xa zidibana nemithwalo emikhulu. Okwangoku, inokuqhekeka kwaye ihlanganiswe kwakhona izihlandlo ezininzi, nto leyo eguquguqukayo ngakumbi kwaye ilula kwinkqubo yokwakha, kwaye ifanelekile kubunjineli bolwandle, iidykes zaselwandle kunye nee-wharves.
