Amanyathelo okwakha i-culvert erhabaxa yentsimbi kwiimeko ezahlukeneyo zemozulu nemozulu

Kwimozulu eyahlukileyoi-culvert yentsimbi erhabaxaamanyathelo okhuseleko lokwakha awafani, ubusika nehlobo, ubushushu obuphezulu kunye nobushushu obuphantsi, okusingqongileyo kwahlukile amanyathelo okwakha nawo ahlukile.

 

1.Amanyathelo okwakha i-corrugated culvert yemozulu eshushu kakhulu

Ø Xa ikhonkrithi yakhiwe ngexesha lobushushu, amanzi okuxuba kufuneka asetyenziswe ukuthatha amanyathelo okupholisa ukulawula ubushushu bokuzalisa ikhonkrithi obungaphantsi kwama-30℃, kwaye kufuneka kuqwalaselwe impembelelo yobushushu obuphezulu ekulahlekelweni kokuwa kwekhonkrithi. Ikhonkrithi ayifanelanga ixutywe namanzi ngexesha lokuthuthwa. 

Ø Ukuba iimeko zikhona, kufuneka igqunywe kwaye ikhuselwe elangeni ukuze kuncitshiswe ubushushu befomwork kunye nokuqinisa; amanzi angafafazwa nakwifomwork kunye nokuqinisa ukuze kuncitshiswe ubushushu, kodwa akufuneki kubekho manzi amileyo okanye anamathelayo kwifomwork ngexesha lokugalela ikhonkrithi.

Ø Iilori zokuthutha zekhonkrithi mazibe nezixhobo zokuxuba, kwaye iitanki mazikhuselwe elangeni. Ø Ikhonkrithi mayixutywe kancinci kwaye ingaphazanyiswa ngexesha lokuthuthwa kwaye ixesha lokuthuthwa malincitshiswe.

Ø Ifomyula kufuneka iqhaqhwe xa ubushushu buphantsi emini kwaye umphezulu wekhonkrithi kufuneka ufume kwaye unyangwe ubuncinane iintsuku ezisi-7 emva kokuqhaqha ifomyula.

 

2.Amanyathelo okwakhaumbhobho we-culvert yentsimbi erhabaxangexesha lemvula

Ø Ukwakhiwa ngexesha lemvula kufuneka kulungiselelwe kwangethuba, zama ukulungiselela ukugqitywa ngaphambi kokuba imvula ifike, izixhobo ezingangeni manzi ezijikeleze umngxuma ukuthintela amanzi angqongileyo ukuba angangeni emngxunyeni.

Ø Yandisa ukuphindaphinda kovavanyo lwamanzi kwizinto zesanti kunye namatye, lungisa umlinganiselo wekhonkrithi ngexesha ukuqinisekisa umgangatho wokuxuba ikhonkrithi.

Ø Imibhobho yentsimbi eqhotsiweyo kufuneka iqiniswe ukuze kuthintelwe ukugqwala. Ø Xa kudityaniswa imibhobho yentsimbi eqhotsiweyo, kufuneka kubekwe indawo yokukhusela imvula yexeshana ukuze kuthintelwe ukukhukuliseka ngamanzi emvula.

Ø Ingqwalasela ekhethekileyo mayinikwe ekukhuseleni imigca yombane, ibhokisi yombane yezixhobo ze-electromechanical ezikwindawo kufuneka igqunywe kwaye kuthathwe amanyathelo okumelana nokufuma, kwaye iingcingo zombane mazigqunywe kakuhle ukuze kuthintelwe ukuvuza kunye neengozi zombane.

 

3. Amanyathelo okwakha i-corrugatedumbhobho we-culvert yentsimbiebusika

Ø Ubushushu obuphakathi ngexesha lokuwelda akufuneki bube ngaphantsi kwe -20℃, kwaye kufuneka kuthathwe amanyathelo okuthintela ikhephu, umoya kunye nezinye iindlela zokunciphisa umahluko kubushushu kwiindawo eziweldayo. Iindawo eziweldayo emva kokuwelda azivumelekanga ukuba zinxibelelane nomkhenkce nekhephu ngoko nangoko.

Ø Umlinganiselo wokuxuba kunye nokuwa kwekhonkrithi kufuneka kulawulwe ngokungqongqo xa kuxutywa ikhonkrithi ebusika, kwaye i-aggregate akufuneki ibe nomkhenkce nekhephu kunye namaqhuma aqandisiweyo. Ngaphambi kokutyisa, amanzi ashushu okanye umphunga kufuneka kusetyenziswe ukuhlamba ipani yokuxuba okanye idrama yomatshini wokuxuba. Umyalelo wokongeza izinto kufuneka ube yi-aggregate kunye ne-water kuqala, uze wongeze isamente emva kokuxuba kancinci, kwaye ixesha lokuxuba kufuneka libe lide ngama-50% kunelo kubushushu begumbi.

Ø Ukugalela ikhonkrithi kufuneka kukhethe usuku olunelanga kwaye kuqinisekiswe ukuba igqityiwe ngaphambi kokuba iphole, kwaye kwangaxeshanye, kufuneka igqunywe kwaye igcinwe ikwimo entle, kwaye akufuneki iqandiswe ngaphambi kokuba amandla ekhonkrithi afikelele kwiimfuno zoyilo.

Ø Ubushushu bekhonkrithi ephuma kumatshini akufuneki bube ngaphantsi kwe-10 ℃, izixhobo zayo zokuthutha kufuneka zibe neendlela zokuthintela ukufudumeza, kwaye kufuneka zinciphise ixesha lokuthutha, ubushushu obungena kwisikhunta akufuneki bube ngaphantsi kwe-5 ℃.

Ø Izithuthi zothutho lwesamente mazibe neendlela zokugcina ubushushu, kwaye zinciphise ixesha lokuthuthwa kwesamente.
