Munyika yekuvaka iri kuramba ichichinja-chinja, zvinhu zvatinosarudza zvinoita basa guru mukugadzira kwete runako rwechivako chete, asiwo mashandiro acho uye kugadzikana kwacho. Chimwe chezvinhu zvakadaro chave chichifarirwa mukuvaka kwemazuva ano isimbi yakagadzirwa nesimbi yakasungirirwa yakagadzirwa nechando. Nzira iyi itsva yekuvaka simbi inopa mabhenefiti akawanda anoita kuti ive sarudzo yakanaka kumapurojekiti ekuvaka emazuva ano.
Simbi yakagadzirwa nesimbi yakanyungudutswa yakagadzirwa nechando inozivikanwa nemaitiro ayo akasiyana ekugadzira, ayo anosanganisira kugadzira simbi patembiricha yemumba uye wozoibatanidza kuti igadzire chikamu chakasimba chechivakwa. Nzira iyi inowedzera simba rechinhu ichi uku ichibvumira magadzirirwo akaomarara anoenderana nezvinodiwa zvemagadzirirwo emazuva ano. Kushandiswa kwesimbi iyi kunonyanya kuoneka muzvivakwa zvirefu, mabhiriji uye zvivakwa zvemaindasitiri uko kusimba nekugara kwenguva refu zvakakosha.
Chimwe chezvinhu zvakanakisisa muchikamu chino ndecheduchivakwa chakasungirirwa chakaumbwa nechandoMapaipi egasi akagadzirwa nesimbi yeA252 Grade 1. Chigadzirwa ichi chinogadzirwa uchishandisa nzira yekuwedera arc ine arc mbiri, iyo inoita kuti kupenya kwepamusoro-soro uye kusimba kwakanaka. Mapaipi edu esimbi anotevedzera mwero weASTM A252 wakagadzwa neAmerican Society for Testing and Materials (ASTM), uyo unovimbisa kuvimbika kwawo uye kushanda kwawo mumabasa akasiyana-siyana. Mapaipi aya anogona kushandiswa zvakasiyana-siyana uye anoshandiswa mumabasa akasiyana-siyana, kubva kumasisitimu ekugovera gasi kusvika pakutsigira zvivakwa.
Zvakanakira kushandisa simbi yakasungirirwa yakagadzirwa nechando muzvivakwa zvemazuva ano zvinopfuura simba rayo. Hunhu hwakareruka hwezvinhu izvi hunobvumira vagadziri vezvivakwa kugadzira zvivakwa zvine hunyanzvi pasina kukanganisa kuchengetedzeka. Izvi zvakakosha zvikuru munzvimbo dzemaguta uko nzvimbo iri pamutengo wakaderera. Pamusoro pezvo, kunyatsogadzirwa kwemaitiro ekugadzira kunoreva kuti zvikamu zvinogona kugadzirwa zvinoenderana nezvinodiwa chaizvo, zvichideredza marara uye zvichiwedzera kushanda zvakanaka kwekuvaka.
Pamusoro pezvo, kugona kwekugadzira simbi yakagadzirwa nesimbi yakasungirirwa hakugoni kufuratirwa. Vagadziri vezvivakwa vari kuwedzera kukwezvwa nechimiro chakanaka, cheindasitiri chinopihwa nechinhu ichi. Chinogona kusiiwa chakavhurika kuti chiite sechisina kugadzirwa, chemazuva ano kana kupedzwa nenzira dzakasiyana-siyana kuti chiwedzere zvimwe zvinhu zvekugadzira. Kuchinjika uku kunobvumira kuratidzwa kwekugadzira uku uchichengetedza chimiro chechivako.
Kambani iyi iri muCangzhou, Hebei Province, uye yave iri pamberi muindasitiri yekugadzira simbi kubvira payakavambwa muna 1993. Kambani iyi ine nzvimbo inosvika 350,000 square metres uye yakadyara mari yakawanda nehupfumi hwese hweRMB 680 miriyoni. Kambani iyi ine vashandi 680 uye yakazvipira kugadzira zvigadzirwa zvesimbi zvemhando yepamusoro zvinosangana nezvinodiwa zvekuvaka kwemazuva ano.
Tichitarisa mberi, kushandiswa kwesimbi yakagadzirwa nesimbi yakasungirirwa yakagadzirwa nechando mukuvaka kucharamba kuchikura. Nekunyanya kutarisisa kuchengetedza nguva uye kushanda zvakanaka, chinhu ichi chinopa vagadziri vezvivakwa nevavaki mhinduro inogutsa. Nekusarudza zvigadzirwa zvakaita sesimbi yedu yakagadzirwa nesimbi yakasungirirwa yakagadzirwa nechandomapaipi egasi, nyanzvi dzeindasitiri dzinogona kuve nechokwadi chekuti mapurojekiti avo haana kungogadzirwa zvakanaka chete, asiwo akagadzirwa zvakanaka uye ane hushamwari kune nharaunda.
Muchidimbu, kuiswa kwesimbi yakagadzirwa nesimbi yakasungirirwa muzvivakwa zvemazuva ano kunomiririra kufambira mberi kukuru mukuvaka. Simba rayo, kushanduka-shanduka, uye runako rwayo zvinoita kuti ive chinhu chakakosha kune vanogadzira mapurani kuti vapfuure miganhu yekugadzira uku vachitevedzera mitemo yekuchengetedza nekuchengetedza. Sezvatinoramba tichigadzira zvinhu zvitsva nekuvandudza zvigadzirwa zvedu, tinoramba takazvipira kutsigira nharaunda yekuvaka nezvinhu zvemhando yepamusoro.
