Ukuphonononga ubuChwephesha boLwakhiwo lweConcrete eNgenelelayo: UbuGcisa bokudala imiphezulu yeDolophu eZinzileyo

Kwiphulo lophuhliso oluzinzileyo lwedolophu, ukusetyenziswa kwekhonkrithi egxunyekwayo kufumene umfutho obonakalayo. Esi sixhobo sivelisa izinto ezintsha, esihlala sibizwa ngokuba "yi-concrete edityanisiweyo evunyiweyo," inika umdibaniso okhethekileyo wobuhle kunye nokusebenza, nto leyo eyenze ukuba ibe lolona khetho lukhethwayo lokudala imiphezulu yedolophu enokungeneka. Kule bhlog, siphengulula kubuchule bolwakhiwo lwekhonkrithi evunyiweyo edibeneyo kwaye siphonononge amandla ayo osetyenziso olubanzi.

Ukwakhiwa kwekhonkrithi ye-permeable aggregate iqala ngokukhethwa kwee-aggregates ezifanelekileyo. Ezi ngqungquthela, ezenza umphezulu oveziweyo wekhonkrithi egqityiweyo, zikhethwa ngokusekelwe ekomeleleni kwazo, amandla kunye nokubonakala kwazo. Nje ukuba iiaggregates zikhethiwe, zixutywa kunye nomxube okhethekileyo wekhonkrithi ovunyelekayo oquka isamente, amanzi, kunye nezinye izongezo ukwenza i-matrix evulekileyo kodwa eyomeleleyo.

Isinyathelo esilandelayo sibandakanya ukufakwa kwekhonkrithi ye-permeable aggregate. Umgangatho ongaphantsi kufuneka ulungiswe ngokufanelekileyo, uqinisekise ukuba uhlangene kwaye awunayo inkunkuma. Ikhosi yesiseko ye-aggregate evumelekileyo okanye igrabile iye ibekwe phantsi ukubonelela ngesiseko esizinzileyo sekhonkrithi. Umxube wekhonkrithi ovunyelekayo ugalelwa kwisiseko, usasazwe ngokulinganayo, kwaye uhlanganiswe kusetyenziswa izixhobo ezikhethekileyo.

Emva kokuba ikhonkrithi ibekwe, umphezulu uvunyelwe ukunyanga ixesha elithile. Ngethuba le nkqubo yokuphilisa, umphezulu uqala ukuqina, kwaye i-aggregates ngaphakathi komxube ngokuthe ngcembe ibonakaliswe. Oku kudala ugqibo oludityanisiweyo olulodwa oluluphawu lwekonkrithi evunyelekayo.

Inyathelo lokugqibela kwinkqubo yolwakhiwo kukugcinwa kunye nokunyamekelwa komphezulu wekhonkrithi we-permeable aggregate. Ukucoca rhoqo kunye nokugcinwa kubalulekile ukuqinisekisa ukusebenza kwexesha elide kunye nokuqina kwezinto eziphathekayo. Ukongezelela, ukuhlolwa kwamaxesha athile kunye nokulungiswa kunokuba yimfuneko ukulungisa nayiphi na imiba okanye umonakalo onokuthi wenzeke ekuhambeni kwexesha.

Ukusetyenziswa kwekhonkrithi edibeneyo evunyiweyo ayiphuculi nje ukungeneka komphezulu wedolophu, kodwa ikwabonelela ngeenzuzo ezininzi zokusingqongileyo. Ngokuvumela amanzi emvula ukuba agqobhoze ngekhonkrithi kwaye azalise amanqanaba amanzi aphantsi komhlaba, kunciphisa umngcipheko wezikhukhula kunye nokunciphisa umthwalo kwiinkqubo zokuhambisa amanzi ezidolophini. Ngaphaya koko, ubume bayo obunemingxuma buxhasa ukukhula kohlaza kwaye bunegalelo ekudalweni kwenkqubo yendalo ephilileyo yasezidolophini.

Xa kujongwe ngaphaya kweenzuzo zangoku zekonkrithi edibeneyo evunyiweyo, ukusetyenziswa kwayo kuyilo lwedolophu kunye nocwangciso lunamandla okuguqula izixeko zethu. Ngokudibanisa le mathiriyeli kwizitrato zethu, iipavumente, kunye neendawo zikawonke-wonke, sinokwenza iindawo ezinokungena nezizinzileyo zedolophu. Oku ke, kunokuba negalelo ekuphuculeni umgangatho womoya, ukunciphisa ungcoliseko lwengxolo, kunye nemekobume yedolophu etofotofo.

Ukuqukumbela, i-aggregate yekonkrithi evunyiweyo imele inyathelo elibalulekileyo kuphuhliso lwedolophu oluzinzileyo. Ubuchwephesha bayo obukhethekileyo bokwakha kunye neenzuzo zokusingqongileyo zenza ukuba ibe yongezelelo oluxabisekileyo kumhlaba wethu wedolophu. Njengoko siqhubeka nokuphonononga ukubanakho kwesi sixhobo sivelisa izinto ezintsha, kusenokwenzeka ukuba siza kubona usetyenziso oluxhaphakileyo kwixesha elizayo, siguqula izixeko zethu zibe ziindawo ezihlaza nezinokuhlalwa ngakumbi.
