ISINGENISO SOKUQHAWULA KAKHULU: Isixazululo sesisekelo esizinzile
Esikhathini lapho ukuqina kubaluleke kakhulu, izixazululo zokwakha ezintsha njengezikulufa zomhlaba zithola ukugcwala okukhulu. Izikulufo zomhlabathi, ezaziwa nangokuthi izinqwaba zesikulufa noma izinhlayiya ze-helical, ziyizinhlaka zensimbi ezifakwe emhlabathini ukuze zinikeze izisekelo ezinzile zezakhiwo ezahlukahlukene, kubandakanya izakhiwo, izibonakaliso, uthango kanye namapulazi elanga. Lezi zikulungisa zenziwa ngensimbi yamandla aphezulu futhi ziza ngosayizi nobukhulu obuhlukile ngokuya ngomthwalo abakudinga ukusekela kanye nezimo zenhlabathi ezizohlangabezana nazo. Idizayini yabo ivumela ukuphazamiseka okuncane ngesikhathi sokufakwa endaweni ezungezile, kubenza babe ngenye indlela enobungane bemvelo yezisekelo zokhonkolo zendabuko. Ngokungafani nezindlela ezijwayelekile, izikulufo ezinomhlabathi zisusa isidingo sokumba okunciphisa ukukhiqizwa imfucuza kanye nokukhishwa kwekhabhoni okuhambisana nemisebenzi yokwakha. Ukuguquguquka okuhlukahlukene kanye nokufakwa kalula kwenza izikulufa zomhlabathi zilungele amaphrojekthi asukela ekusetshenzisweni okuncane kokuhlala ezindaweni ezinkulu zezentengiso. Zibonisa ukuthi zilusizo ikakhulukazi ezindaweni ezinezimo zenhlabathi eziyinselele noma indawo engazinzile lapho izisekelo ezijwayelekile zingahle zehluleke noma zibize kakhulu.
