Ingabe izibani zasemgwaqweni zelanga zidinga ukuvikelwa kombani okwengeziwe?

Ehlobo lapho umbani uvame kakhulu, njengesisetshenziswa sangaphandle, ingabe izibani zasemgwaqweni zelanga zidinga ukwengeza izisetshenziswa zokuvikela umbani?Imboni yokukhanya komgwaqo i-Tianxiangikholelwa ukuthi uhlelo oluhle lokubeka phansi impahla lungadlala indima ethile ekuvikelweni kombani.

Ukuvikela umbani izindlela zokumisa izibani zasemgwaqweni zelanga

Ukukhetha izinhlobo ezahlukene zemishini yokubeka phansi kuyisinyathelo sokuqala sokuvikela umbani wezibani zasemgwaqweni zelanga. Imishini evamile yokubeka phansi ihlanganisa i-steel bar grounding, igridi yamandla ephansi, kanye negridi ephansi. Izinyathelo ezithile zokuqalisa zimi kanje:

1. Indlela yokumisa ibha yensimbi

Bamba umgodi ojulile ongu-0.5m ngaphansi kwesisekelo sokukhanya komgwaqo welanga, beka ibha yensimbi ende engu-2m, bese uxhuma isisekelo sokukhanya komgwaqo welanga kubha yensimbi, futhi ekugcineni ugcwalise umgodi.

2. Indlela yokumisa igridi yamandla

Xhuma izintambo zokukhanya komgwaqo welanga esigxotsheni segridi yamandla eseduze ukuze uxhume umjikelezo wesibani somgwaqo welanga kugridi yaphansi.

3. Indlela yokumisa igridi ephansi

Bamba umgodi ojulile ongu-1m ngaphansi kwesibani somgwaqo welanga, sebenzisa intambo emise okwendandatho ukuze uxhume ukukhanya komgwaqo welanga ngesigxobo sensimbi kanye negridi yensimbi yensimbi ngaphansi komhlaba, bese ugcwalisa umgodi ngokhonkolo.

Izinyathelo zokuphepha zokuvikela umbani phansi kwezibani zasemgwaqweni zelanga

1. Umshini ophansi kufanele uthintane kahle nelambu lomgwaqo lelanga ngokwalo.

2. Khetha ukujula kwesisekelo esifanele. Akufanele kube nokujula kakhulu, njengoba kungase kwandise ukumelana komhlabathi; akufanele ijule kakhulu, ngoba ingase ibangele inhlabathi ukuba ibe nomswakama kakhulu, inciphise ukumelana nokuphansi futhi ithinte uhlelo lonke lokubeka phansi.

3. Njalo hlola imigqa yaphansi kanye nokumelana nesisekelo ukuze uqinisekise ubuqotho besistimu yokubeka phansi.

Izibani zasemgwaqweni zelanga ze-Tianxiangzonke zifakwe amakheji aphansi, enziwe ngezinsimbi zensimbi futhi kakade adlala indima ethile ekuvikelweni kombani.

Okwesibili, umbani uvame ukushaya izakhiwo ezinde noma izinhlaka zensimbi, kunokuba uhlasele ngokungahleliwe noma iyiphi into. Phela, izakhiwo ezingokomzimba zikhawulela isimiso sayo sokukhiqiza. Ama-solar ethu awabukhali futhi awande kakhulu, ngakho-ke amathuba okushaywa umbani mancane kakhulu.

Okwesithathu, singabhekisela ezintweni zokucwaninga zombani ezinegunya. Nansi amazwi acashuniwe: “Ngokwezibalo, unyaka ngamunye emhlabeni wonke abantu abashaywa umbani bangaphezu kuka-4 000. Uma inani labantu emhlabeni liyizigidi eziyizinkulungwane ezingu-7, isilinganiso samathuba okuthi umuntu ngamunye ashaywe umbani angaba munye ezigidini ezingu-1,75.” Ngokwe-Federal Emergency Management Agency yase-United States, isilinganiso samathuba okuba umuntu waseMelika ashaywe umbani acishe abe yizigidi ezingu-60.” Amathuba esethi eyodwa kweziyi-1,000 zamalambu elanga ashaywa umbani unyaka ngamunye angu-1,000 * 1/600,000 = 1.6‰, okusho ukuthi kuzothatha iminyaka engu-2,500 ukuthi isethi eyodwa ishaywe kumasethi ayi-1,000.

Kunesinye isizathu esingeziwe. Kungani izinto eziningi zikagesi zasedolobheni zinezinyathelo zokuvikela umbani? Kungenxa yokuthi amandla kagesi edolobha axhunywe ngokuhambisana nochungechunge, futhi uma isibani esisodwa sishaywa umbani, singalimaza inqwaba yezibani eziseduze. Kodwa-ke, izibani zasemgwaqweni zelanga azidingi ukuxhunywa komunye nomunye futhi azinalo uchungechunge noma ukuxhumana okuhambisanayo.

Sengiphetha, sikholelwa ukuthi izibani zasemgwaqweni zelanga azidingi izinyathelo ezengeziwe zokuvikela umbani. Nansi eminye yesipiliyoni sethu:

1. Uma ubude bokukhanya komgwaqo welanga buphansi futhi kunezakhiwo ezinde noma izihlahla eduze ukuze zihehe umbani, amathuba okushaywa umbani ngokuqondile aphansi.

2. Amaphaneli elanga esimanje awawona amakhondaktha abukhali futhi ngokuvamile asebenzisa amafreyimu angewona ezensimbi, okuwenza mancane amathuba okuheha umbani.

3. Ezindaweni ezinomsebenzi wombani ophezulu, uhlelo oluphelele lokuvikela umbani (i-grounding + SPD + induku yombani) kufanele ifakwe.
