Izinzuzo Zesakhiwo Esihlanganisiwe Esibunjiwe Esibandayo

Izinzuzo Zesakhiwo Esihlanganisiwe Esihlanganisiwe Esibunjiwe Esibandayo

Incazelo emfushane:

Lapho wakha izakhiwo nezakhiwo, ukukhetha izinto zokwakha kudlala indima ebalulekile ekuqinisekiseni ukuqina nokuqina komkhiqizo wokugcina. Enye yezinto ezidumile embonini yokwakha insimbi yesakhiwo ehlanganisiwe eyenziwe ngobumba obubandayo. Le nto entsha inikeza izinzuzo eziningi, okwenza kube ukukhetha kokuqala kwamaphrojekthi amaningi okwakha.

Sithumelele i-imeyili

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Insimbi eyakhiwe ngokubandayo ikhiqizwa ngokugoba nokwenza amashidi ensimbi noma amakhoyili ekushiseni kwegumbi ngaphandle kokusebenzisa ukushisa. Le nqubo ikhiqiza izinto eziqinile nezihlala isikhathi eside kunensimbi eyakhiwe ngokushisayo. Le nsimbi eyakhiwe ngokubandayo inikeza izinzuzo eziningana ezibalulekile uma ihlanganiswa ndawonye ukuze yakhe izingxenye zesakhiwo.

Enye yezinzuzo eziyinhloko ze-umkhuhlane isakhiwo esihlanganisiwe esakhiwe insimbi iyisilinganiso sayo samandla aphezulu nesisindo. Lokhu kusho ukuthi inikeza amandla aphezulu ngenkathi ilula kakhulu, okwenza kube lula ukuyiphatha nokuyithutha ngesikhathi sokwakha. Ngaphezu kwalokho, amandla aphezulu ensimbi eyakhiwe ngokubandayo enza imiklamo yesakhiwo emincane nephumelelayo ekhulisa isikhala futhi inciphise ukusetshenziswa kwezinto.

Enye inzuzo ebalulekile yensimbi eyakhiwe ngokushintshwa eyakhiwe ngokubandayo ukufana kwayo kanye nokuvumelana kwayo. Inqubo yokwakha okubandayo iqinisekisa ukuthi insimbi igcina izakhiwo ezihambisanayo zomshini kuyo yonke impahla, okuholela ekusebenzeni okubikezelwayo nokuthembekile. Lokhu kuvumelana kubalulekile ekuqinisekiseni ubuqotho besakhiwo kanye nokuphepha kokwakhiwa kokugcina.

Ngaphezu kwamandla nokungaguquguquki, insimbi yokwakha ehlanganisiwe ebandayo inikeza ukunemba okuhle kakhulu kobukhulu kanye nokunemba. Inqubo yokwakha ebandayo ivumela ukubekezelelana okuqinile kanye nokubumba okunembile, okuqinisekisa ukuthi izingxenye zesakhiwo zihlangana kahle ngesikhathi sokuhlanganiswa. Leli zinga lokunemba libalulekile ekufinyeleleni umkhiqizo oqediwe osezingeni eliphezulu, okhangayo ngokubonakalayo.

Ngaphezu kwalokho, insimbi yokwakha eyenziwe nge-Welded ebandayo iyakwazi ukushintshashintsha futhi ingenziwa ngokwezifiso ukuze ihlangabezane nezidingo ezithile zephrojekthi. Ingakhiwa kalula futhi yenziwe ibe yizinhlobonhlobo zemidwebo kanye nokucushwa, okuvumela ukudalwa kwemiklamo yezakhiwo eyinkimbinkimbi. Lokhu kuguquguquka kwenza ifaneleke ezinhlobonhlobo zezicelo kusukela ekwakhiweni kwezindlu kuya ezakhiweni zezimboni.

Ukusetshenziswa kwensimbi yokwakha ebandayo eyenziwe nge-Welded nayo inegalelo emikhubeni yokwakha esimeme. Ukukhanya kwayo kunciphisa umthwalo ophelele esakhiweni sesisekelo kanye nesisekelo, okuholela ekongeni izindleko ezingaba khona kanye nezinzuzo zemvelo. Ngaphezu kwalokho, ukuphindeka kwensimbi kuyenza ibe ukukhetha okunobungani nemvelo kumaphrojekthi okwakha.

Ngamafuphi, insimbi yokwakha ehlanganisiwe ebandayo inikeza izinzuzo eziningi ezenza kube ukukhetha okukhangayo kumaphrojekthi okwakha. Isilinganiso sayo samandla aphezulu kuya kwesisindo, ukuhambisana, ukunemba, ukuguquguquka kanye nokusimama kwenza kube yinto ebalulekile yokwakha izakhiwo eziqinile nezisebenzayo. Njengoba imboni yokwakha iqhubeka nokukhula, insimbi yokwakha ehlanganisiwe ebandayo izodlala indima ebalulekile ekwakheni izakhiwo kanye nengqalasizinda yesikhathi esizayo.
