Ngoku izakhiwo eziphakamileyo zinyuka ukusuka emhlabeni, kodwa ngubani onokunikela ingqalelo ukuba ngubani osemva koku kuthula, umsebenzi uthatha umngcipheko omkhulu, ukuze kuqinisekiswe ukuba umzimba wabantu, uya kubona umnatha wentambo.

1. Umnatha wokhuseleko kufuneka uxhonywe ngaphantsi kwendawo yokusebenza ephezulu;Xa ubude besakhiwo bungaphezu kwe-4m, umnatha wokhuseleko kufuneka usekwe ngokuthe ngcembe unyuka eludongeni, emva koko kusekwe umnatha osisigxina rhoqo nge-4m; isakhelo sangaphandle, isakhelo sebhulorho, imingxuma ephezulu nasezantsi kufuneka imiselwe iminatha yokhuseleko. intonga exhasayo; Umsantsa phakathi komphetho ongaphakathi womnatha kunye nodonga ungaphantsi kwe-15cm; Umgama phakathi kweyona ndawo iphantsi yomnatha kunye nomphezulu wento engezantsi kufuneka ube mkhulu kune-3m. Ububanzi bentloko encinci Ipali yomthi mayingabi ngaphantsi kwe-7cm, ububanzi bentloko encinci yepali ye-bamboo abuyi kuba ngaphantsi kwe-8cm, kwaye isithuba seentonga zokuhombisa iintambo aziyi kuba nkulu kune-4m.

2.Hlola ukuba umnatha wokhuseleko udliwe kwaye wonakaliswe ngaphambi kokusetyenziswa.Ukwakha ukuqinisekisa ukuba umnatha wokhuseleko uphelele kwaye uyasebenza, ukuxhaswa okufanelekileyo, ukunyanzeliswa kweyunifomu, akukho zixhobo kwinethiwekhi.Umnatha wokhuseleko awusayi kuqhaqhwa okanye wonakaliswe ngexesha lokwakha.Iya kuchithwa kuphela xa umsebenzi uqhutywa ngaphandle kokuphakama.Xa umnatha wokhuseleko owenziweyo ufuna ukuchithwa okwethutyana ngenxa yolwakhiwo, iyunithi yokwakha kufuneka ikwazise kwaye icele imvume yeyunithi yokumisa phambi kokuqhawulwa.Emva kokugqiba. yokwakhiwa, iyunithi yokwakha kufuneka iqalise ngokukhawuleza umsebenzi ngokuhambelana nezibonelelo kwaye iphumelele ukuhlolwa kweyunithi yokwakhiwa ngaphambi kokuba isetyenziswe.

3. umnatha wentambo ukucoca rhoqo inkunkuma kumnatha, kumnatha ngaphezu kokuphunyezwa kwemisebenzi ye-welding, kufuneka ithathe amanyathelo asebenzayo okuthintela iintlantsi ze-welding ziwela kumnatha; Musa ukuba nexesha elide le-asidi enzulu kunye nomsi wealkali ngeenxa zonke. umnatha.
