Izinyathelo zokuqapha ukwakhiwa kwe-culvert ehlanganisiwe yensimbi ezimweni zezulu nezimo zezulu ezahlukene

Ezimweni zezulu ezahlukenei-culvert ehlanganisiwe yensimbiIzinyathelo zokuphepha zokwakha azifani, ubusika nehlobo, izinga lokushisa eliphezulu kanye nezinga lokushisa eliphansi, imvelo ihlukile izindlela zokwakha nazo zihlukile.

 

1.Izindlela zokwakha i-corrugated culvert enesimo sezulu esishisayo esiphezulu

Ø Uma ukhonkolo wakhiwa ngesikhathi sokushisa, amanzi okuxuba kufanele asetshenziswe ukuthatha izinyathelo zokupholisa ukulawula izinga lokushisa lokugcwalisa ukhonkolo elingaphansi kuka-30℃, futhi kufanele kucatshangelwe ukuthi izinga lokushisa eliphezulu lingathinta kanjani ukulahlekelwa ukubhidlika kokhonkolo. Ukhonkolo akufanele uxutshwe namanzi ngesikhathi sokuthuthwa. 

Ø Uma izimo zitholakala, kufanele zimbozwe futhi zivikelwe elangeni ukuze kuncishiswe izinga lokushisa lefomu kanye nokuqinisa; amanzi angafafazwa futhi kufomu kanye nokuqinisa ukuze kuncishiswe izinga lokushisa, kodwa akufanele kube namanzi amile noma anamathelayo kufomu ngesikhathi kuthululwa ukhonkolo.

Ø Amaloli okuthutha ekhonkrithi kufanele abe namadivayisi okuxuba, futhi amathangi kufanele avikelwe elangeni. Ø Ikhonkrithi kufanele ixutshwe kancane futhi ngaphandle kokuphazamiseka ngesikhathi sokuthuthwa futhi isikhathi sokuthuthwa kufanele sincishiswe.

Ø Ifomu kufanele liqaqwe lapho izinga lokushisa liphansi emini futhi ubuso bekhonkrithi kufanele bufakwe umswakama futhi bulungiswe okungenani izinsuku eziyi-7 ngemuva kokuqaqa ifomu.

 

2.Izinyathelo zokwakhaipayipi le-culvert lensimbi eboshiwengesikhathi semvula

Ø Ukwakhiwa ngesikhathi semvula kufanele kuhlelwe kusenesikhathi, zama ukuhlela ukuqedela ngaphambi kokuba imvula ifike, izindawo ezingangeni manzi ezizungeze umgodi ukuvimbela amanzi azungezile ukuthi angangeni emgodini.

Ø Khulisa imvamisa yokuhlolwa kokuqukethwe kwamanzi kwezinto zesihlabathi namatshe, lungisa isilinganiso sekhonkrithi ngesikhathi ukuqinisekisa ikhwalithi yokuxuba ikhonkrithi.

Ø Amapayipi e-culvert ahlanganisiwe ensimbi kufanele aqiniswe ukuze kuvinjelwe ukugqwala. Ø Uma kuhlanganiswa amapayipi e-culvert ahlanganisiwe ensimbi, kufanele kubekwe indawo yokuvikela imvula yesikhashana ukuze kuvinjelwe ukuguguleka kwamanzi emvula.

Ø Kufanele kuqashelwe ngokukhethekile ukuvikelwa kwezintambo zikagesi, ibhokisi likagesi lemishini kagesi esendaweni kufanele limbozwe futhi kuthathwe izinyathelo zokuvikela umswakama, futhi izintambo zikagesi kufanele zifakwe kahle ukuze kuvinjelwe ukuvuza kanye nezingozi zokushayiswa ugesi.

 

3. Izindlela zokwakha i-corrugatedipayipi lensimbi yokudonsa amanziebusika

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

Ø Isilinganiso sokuxuba kanye nokuwa kwekhonkrithi kufanele kulawulwe ngokuqinile lapho kuhlanganiswa ikhonkrithi ebusika, futhi i-aggregate akufanele ibe neqhwa neqhwa kanye nezigaxa eziqandisiwe. Ngaphambi kokuphakela, amanzi ashisayo noma umusi kufanele kusetshenziswe ukuhlanza ipani lokuxuba noma isigubhu somshini wokuxuba. Uhlelo lokufaka izinto kufanele lube yi-aggregate bese unisela kuqala, bese ufaka usimende ngemva kokuxuba kancane, futhi isikhathi sokuxuba kufanele sibe isikhathi eside ngo-50% kunaleso esisezingeni lokushisa legumbi.

Ø Ukuthulula ukhonkolo kufanele kukhethe usuku olunelanga futhi kuqinisekiswe ukuthi kuqediwe ngaphambi kokuba kuphole, futhi ngesikhathi esifanayo, kufanele kufakwe umswakama futhi kugcinwe kusesimweni esihle, futhi akufanele kuqandiswe ngaphambi kokuba amandla ekhonkolo afinyelele izidingo zomklamo.

Ø Izinga lokushisa likakhonkolo eliphuma emshinini akufanele libe ngaphansi kuka-10 ℃, imishini yayo yokuthutha kufanele ibe nezindlela zokuvimbela ukushisa, futhi kufanele inciphise isikhathi sokuthutha, izinga lokushisa eliya esikhumbeni akufanele libe ngaphansi kuka-5 ℃.

Ø Izimoto zokuthutha ezenziwe ngokhonkolo kufanele zibe nezindlela zokugcina ukushisa, futhi zinciphise isikhathi sokuthutha esenziwe ngokhonkolo.
