Liliphi Ixesha Elifanelekileyo Lokusebenzisa Itrowel Yamandla Ekhonkrithi?
Itrowel yamandla ekhonkrithi ingenza ukugqitywa komgangatho kube ngokukhawuleza, kube tyaba kwaye kuhambelane ngakumbi, kodwa kuphela xa ingena kwislab ngexesha elifanelekileyo. Ukuba umatshini uqala kwangethuba kakhulu, ipani okanye iiblayidi zinokuphazamisa ikhonkrithi ethambileyo. Ukuba iqala kade kakhulu, umphezulu uba nzima ukuvala kwaye umqhubi kufuneka asebenze ngokungathi uzama ukupolisha ilitye.
Kwabakhi, abaphathi bendawo kunye nabathengi bezixhobo, ixesha letrowel libaluleke ngokufanayo namandla enjini, ububanzi bokusebenza okanye uhlobo lweblade. Umatshini olungileyo awunakunceda ukuba ixesha lingabi lihle, kodwa ixesha elifanelekileyo linokunceda umatshini usebenze kakuhle.
Kutheni Kubalulekile Ukuba nexesha Elifanelekileyo Ekugqibeni Umgangatho Wekhonkrithi
Ukugqitywa kwekhonkrithi akulawulwa yiwotshi yodwa. Ilawulwa ngokubeka isantya, uyilo lomxube, ubukhulu beslabhu, imozulu, umoya, ubushushu, ukufuma kunye nobungakanani bamanzi aphumayo kumphezulu. Iislabhu ezimbini ezigalelwe ngosuku olunye zinokulunga ngamaxesha ahlukeneyo, ngakumbi ukuba enye iselangeni ngqo kwaye enye iphantsi komthunzi. Yiyo loo nto abaqhubi abanamava bejonga ikhonkrithi ngaphezu kokubukela iifowuni zabo.
Ukuqala umatshini wetrowel yamandla Ingawuvala umphezulu ngaphambi kokuba umoya namanzi aphumayo aphume. Umbutho weSizwe weReady Mixed Concrete Association ichaza ukuba ukuqhekeka kungenzeka xa umphezulu uvalwe ngokugqitywa kwangaphambi kwexesha ngelixa umoya okanye amanzi aphumayo ehlala engaphantsi. Ngolwimi olulula, umphezulu ungabonakala ugqityiwe, kodwa ngaphantsi kwawo kusazama ukuphefumla.
Indawo esekelwe kubungqina: ukucofa itrowelling kwangethuba akusiyompazamo nje encinci yobuhle. Inethiwekhi yekhonkrithi ichaza ukuba xa ukugqitywa kuqala kwangethuba kakhulu kwaye kuvala umphezulu ngaphambi kokuba ukopha kugqitywe, umoya okanye amanzi anokubanjwa ngaphantsi komaleko ongaphezulu oxineneyo, nto leyo edala izithuba ezibuthathaka kumphezulu.
