Zinthu zomwe zikufunika kusamaliridwa pakupanga ng’anjo yopangira ng’anjo (ramming material)

Pali masitepe ambiri panjira yonse yopangira ng’anjo yowotchera (ramming material), ndipo knotting ndi zina mwazinthu zofunika kwambiri. Ndipo ndondomeko ya knotting ingakhudzenso moyo wautumiki wa ng’anjo.

Luoyang Songdao amatanthauzira zomwe zikuyenera kutsatiridwa popanga zida zopangira ng’anjo (ramming material) kuti zitsimikizire kuti sizikhudza moyo wautumiki wa ng’anjo?

1. Sanjani momwe ntchito imagwirira ntchito, koma kuwonjezera apo, pali zodzitetezera zambiri pakapangidwe kazinthu zopangira ramming.

Mwachitsanzo, musanayambe kumanga mfundo, kuonetsetsa kuti magetsi akugwiritsidwa ntchito komanso kusintha kwa kayendedwe ka madzi, m’pofunikanso kukonzekera pasadakhale kudzera mwa antchito a polojekiti iliyonse. Zoonadi, zimaphatikizansopo kuti ogwira ntchito saloledwa kubweretsa zinthu zoyaka moto ndi zophulika pamalo ogwirira ntchito, kuphatikizapo mafoni a m’manja, makiyi ndi zinthu zina.

2. Kuonjezera mchenga powonjezera ng’anjo yopangira ng’anjo (ramming material) ndi njira yokhala ndi zofunikira kwambiri. Mwachitsanzo, mchenga uyenera kuwonjezeredwa nthawi imodzi, ndipo suyenera kuwonjezeredwa mumagulu. Inde, powonjezera mchenga, onetsetsani kuti mchenga ukufalikira Pansi pa ng’anjo sayenera kuwunjidwa mulu, mwinamwake tinthu tating’ono ta mchenga tidzalekanitsidwa.

3. Chikumbutso chapadera cha ng’anjo yolowera m’ng’anjo (za ramming): Pomanga mfundo, iyenera kuyendetsedwa molingana ndi njira yogwedeza kaye kenako ndikugwedezeka. Ndipo tcherani khutu ku njira yowonetsetsa kuti ntchitoyo ikhale yopepuka komanso yolemetsa. Ndipo chogwedezacho chiyenera kulowetsedwa pansi nthawi imodzi, ndipo nthawi iliyonse akalowetsa ndodo, azigwedezeka kasanu ndi katatu mpaka khumi.

4. Pansi pa ng’anjo ikatha, onetsetsani kuti ikhoza kuikidwa mumphika wouma mokhazikika. Ndi njira iyi yokha yomwe tingatsimikizire kuti kupanga kwake kumakhala kofanana, kawirikawiri kudzakhala mphete ya katatu ya annular. Zoonadi, pali njira zambiri zomwe ziyenera kutsatiridwa mu ndondomeko yonse ya knotting. Ndipo sitepe lirilonse silinganyalanyazidwe.
