Izinyathelo zokuqapha ukwakhiwa kwekholvethi kathayela esimweni sezulu esihlukile nezimo zezulu

Ezimweni zezulu ezahlukeneinsimbi kathayelaizinyathelo zokwakha azifani, ebusika nasehlobo, izinga lokushisa eliphezulu nokushisa okuphansi, imvelo ihlukile izinyathelo zokwakha nazo zihlukile.

 

1.Izinga lokushisa eliphezulu lezinyathelo zokwakha amakholethi kathayela

Ø Uma ukhonkolo wakhiwe ngesikhathi esishisayo, amanzi okuxutshwa kufanele asetshenziselwe ukuthatha izinyathelo zokupholisa ukulawula izinga lokushisa likakhonkolo elingaphansi kuka-30℃, kanye nomthelela wokushisa okuphezulu ekulahlekeni kokuwa kukakhonkolo kufanele kubhekwe. Ukhonkolo akufanele uhlanganiswe namanzi ngesikhathi sokuthutha. 

Ø Uma izimo zikhona, kufanele zimbozwe futhi zivikeleke elangeni ukuze kuncishiswe izinga lokushisa le-formwork kanye nokuqiniswa; amanzi angabuye afafazwe ku-formwork kanye nokuqiniswa ukuze kuncishiswe izinga lokushisa, kodwa akufanele kube namanzi amile noma abambelele ku-formwork ngesikhathi sokuthululwa kukakhonkolo.

Ø Amaloli athutha ukhonkolo kufanele abe nezinto zokuxuba, futhi amathange avikelwe elangeni. Ø Ukhonkolo kufanele uxutshwe kancane futhi ungaphazanyiswa ngesikhathi sokuthutha futhi isikhathi sokuthutha kufanele sincishiswe.

Ø I-formwork kufanele ihlakazwe lapho izinga lokushisa liphansi phakathi nosuku futhi indawo ekhonkolo kufanele imanziswe futhi yelaphe isikhathi esingekho ngaphansi kwezinsuku eziyi-7 ngemuva kokudilizwa kwefomu.

 

2.Izinyathelo zokwakhaipayipi likathayela le-culvertngesikhathi sezimvula

Ø Ukwakhiwa ngesikhathi semvula kufanele kuhlelwe kusenesikhathi, zama ukuhlela ukuqeda ngaphambi kwemvula, izindawo ezingangeni emanzini ezizungeze umgodi ukuvimbela amanzi azungezile ukuthi angagelezi emgodini.

Ø Khulisa imvamisa yokuhlolwa kokuqukethwe kwamanzi esihlabathini nasezintweni zamatshe, lungisa isilinganiso sikakhonkolo ngesikhathi ukuze uqinisekise izinga lokuxutshwa kukakhonkolo.

Ø Amapayipi kathayela kathayela kufanele aqiniswe ukuze agweme ukugqwala. Ø Uma uxhuma amapayipi kathayela wensimbi, kufanele kumiswe umpheme wesikhashana ukuze kuvinjwe ukuguguleka kwamanzi emvula.

Ø Kufanele kuqashelwe ngokukhethekile ukuvikelwa kwezintambo zikagesi, ibhokisi likagesi lempahla esebenza ngogesi esendaweni kufanele limbozwe futhi kuthathwe izinyathelo zokuvikela umswakama, futhi izintambo zikagesi kufanele zivalwe kahle ukuze kuvinjwe ukuvuza kanye nezingozi zogesi.

 

3.Izinyathelo zokwakhiwa kukathayelaipayipi lensimbi ye-culvertebusika

Ø Izinga lokushisa elizungezile ngesikhathi sokushisela akumele libe ngaphansi kuka -20℃, futhi kufanele kuthathwe izinyathelo zokuvimbela iqhwa, umoya nezinye izinyathelo zokunciphisa umehluko wokushisa wamajoyinti ashiselwe. Amalunga ngemva kokushisela anqatshelwe ngokuphelele ukuthintana neqhwa neqhwa ngokushesha.

Ø Isilinganiso sokuxuba kanye nokuwa kukakhonkolo kufanele kulawulwe ngokuqinile lapho kuhlanganiswa ukhonkolo ebusika, futhi ukuhlanganisa akufanele kube neqhwa neqhwa nezigaxa eziqandisiwe. Ngaphambi kokuphakela, amanzi ashisayo noma isitimu kufanele kusetshenziselwe ukugeza ipani lokuxuba noma isigubhu somshini wokuhlanganisa. Ukuhleleka kokwengeza izinto kufanele kube okuhlanganisiwe namanzi kuqala, bese wengeza usimende ngemva kokuxuba okuncane, futhi isikhathi sokuxuba kufanele sibe ngu-50% ubude kunaleso ekamelweni lokushisa.

Ø Ukuthululwa kukakhonkolo kufanele kukhethe usuku olunelanga futhi kuqinisekise ukuthi kuqedwa ngaphambi kokupholisa phansi, futhi ngesikhathi esifanayo, kufanele kufakwe intuba futhi kugcinwe, futhi akufanele kuqandiswe ngaphambi kokuba amandla kakhonkolo afinyelele izidingo zokuklama.

Ø Ukhonkolo ophuma emshinini wokushisa akufanele ube ngaphansi kuka-10 ℃, imishini yayo yokuthutha kufanele ibe nezinyathelo zokuhlukanisa, futhi kufanele ikhulise ukufinyezwa kwesikhathi sokuthutha, izinga lokushisa lingene esikhunjini akufanele libe ngaphansi kuka-5 ℃.

Ø Izimoto zokuhamba zikakhonkolo kufanele zibe nezinyathelo zokulondoloza ukushisa, futhi zinciphise isikhathi sokuhamba sikakhonkolo.
