Usetyenziso lweSamente eyoNgezelelweyo eKhawulezayo yokuSeta i-Concrete Admixture Accelerator ye-Tunnel Spraying Construction

Usetyenziso lweSithako seConcrete: Iseti ekhawulezayo yeConcrete Admixture Accelerator yeTonnel yokutshiza iSakhiwo kunye noKwakha

Kutheni Usebenzisa i-accelerator yokuSeta ngokukhawuleza kwiiToneli?

Ukwakhiwa kwepaseji kufuna uncedo olukhawulezayo nolunamandla. Abasebenzi batshiza ikhonkrithi kwiindonga zepaseji ukuze babambe umhlaba. Le ndlela ibizwa ngokuba yi-shotcreting. Ngaphandle koncedo, ikhonkrithi eqhelekileyo ithatha ixesha elide ukuqina. Oko kunciphisa umsebenzi kwaye kusongela ukhuseleko. I-accelerator ye-concrete yokudibanisa ekhawulezayo ilungisa le ngxaki.

Esi songezo senza ikhonkrithi ibekwe kwimizuzu, hayi iiyure. Isebenza kakuhle kwi-shotcreting yomxube omanzi okanye owomileyo. Isiphumo kukufumana amandla kwangoko, ukunamathela ngcono kakhulu, kunye ne-rebound encinci (imveliso elahliweyo etsibayo isuka kwindawo ephezulu). Ezi nzuzo zigcina imisebenzi kwishedyuli kwaye zinciphisa iindleko.

Ukusetyenziswa kweQhinga kwiiProjekthi zokwenyani

Kwiitonela zeentaba, imigodi engaphantsi komhlaba, okanye iinkqubo zemetro, ixesha libalulekile. I-accelerator ivumela amaqela ukuba afake iileya ngokukhawuleza ngaphandle kokulinda. Ikwanceda xa usebenza kwimozulu ebandayo. Ukubanda kuyacothisa ukuseta okuqhelekileyo– kodwa i-admixture igcina impendulo iqhubeka.

Abasebenzi baxhomekeke kuyo ngomsebenzi wokulungisa imeko engxamisekileyo nabo. Ukuba umphezulu wodonga lwetonela uyaqhekeka okanye utshintshe, bafuna uncedo olukhawulezileyo. Umxube wokumisa ngokukhawuleza uzalise izithuba kwaye uzinzise indawo ngokukhawuleza. Ukhuseleko kunye nokhuseleko luyaphucula njengoko isakhiwo sibambe ngokuqinileyo ngokukhawuleza.

Imveliso idibanisa ngokufanelekileyo kunye nekhonkrithi kunye namanzi. Iyanelisa imigangatho yamazwe ngamazwe yokuqina nokusebenza. Akukho sixhobo esisodwa esifunekayo– yongeza ngokulula idosi efanelekileyo ngexesha lokudibanisa. Ukusetyenziswa ngokugqithisileyo kunokubangela iseti yeflash, ngoko landela imiyalelo ngononophelo.

Ukusebenza kakuhle Unokuxhomekeka

Uvavanyo lwengingqi lubonisa iziphumo ezithe gqolo kuzo zonke iingxaki ezahlukeneyo. Iibhondi zekhonkrithi ngokukhuselekileyo kwi-rock kunye ne-mesh yentsimbi. Ukucutheka kuhlala kuncitshisiwe, oku kuthetha ukuba iifractures zincinci kamva. Ukumpompa kunye nokutshiza kuhlala kugudile, nangona i-accelerator ifakiwe.

Iingcali zikhetha le ngxubevange ngenxa yokuba ibonelela ngesantya ngaphandle kokuncama umgangatho ophezulu. Ixhasa iindlela zangoku zetonela ezifuna impumelelo, ukhuseleko, kunye nokuthembeka suku ngalunye.
