Pehea e ʻike ai i nā paipu kila hoʻopunipuni a haʻahaʻa:
1. ʻO nā paipu kila mānoanoa a haʻahaʻa hoʻi i ka pelu ʻia. ʻO nā paʻi he mau laina pelu like ʻole i hana ʻia ma ka ʻili o nā paipu kila mānoanoa. Holo pinepine kēia hemahema ma ka ʻaoʻao longitudinal o ka huahana. ʻO ke kumu o ka hoʻopili ʻana ʻo ia ka ʻimi ʻana o nā mea hana shoddy i ka maikaʻi a ʻoi aku ka nui o ka hoʻemi ʻana, e hopena i nā pepeiao. E hana ʻia ka pelu ʻana i ke kaʻina ʻōwili e hiki mai ana. E pohā ka hua i hoʻopili ʻia ma hope o ke kulou ʻana, a e hoʻemi nui ʻia ka ikaika o ke kila.
2. ʻO nā paipu kila mānoanoa a haʻahaʻa i hoʻopaʻa ʻia ma luna o ka ʻili. ʻO ka Pockmarking kahi kīnā ʻole like ʻole ma ka ʻili kila ma muli o ka ʻaʻahu koʻikoʻi o ka ʻōwili ʻōwili. ʻOiai e ʻimi ana nā mea hana o nā paipu kila mānoanoa me ka mānoanoa i ka waiwai, ʻoi aku ka nui o ka groove rolling ma mua o ka maʻamau.
3. ʻO ka ʻili o nā paipu kila mānoanoa hoʻopunipuni ka maʻi maʻi. ʻElua kumu: (1). ʻAʻole kūlike nā mea o nā paipu kila hoʻopunipuni a he nui nā mea haumia. (2). ʻO nā mea hana alakaʻi o nā mea hana hoʻopunipuni a haʻahaʻa he maʻalahi a maʻalahi hoʻi e pili i ke kila. Hiki i kēia mau mea haumia ke hana maʻalahi ma hope o ka nahu ʻana i nā wili.
4. Hiki i ka ʻili o nā paipu kila mānoanoa a haʻahaʻa i nā māwae no ka mea he adobe kona mea maka, a he nui nā pores. Aia ka adobe i ke koʻikoʻi wela i ka wā o ka hoʻomaloʻo ʻana, e hana ana i nā māwae, a ʻike ʻia nā māwae ma hope o ka ʻōwili ʻana.
5. ʻO nā paipu kila mānoanoa a haʻahaʻa, he maʻalahi ke ʻohi. ʻO ke kumu, he maʻalahi a maʻalahi nā mea hana o nā mea hana paipu kila mānoanoa a haʻahaʻa e hana i nā burrs a ʻoki i ka ʻili o ke kila. ʻO nā ʻōpala hohonu e hoʻemi i ka ikaika o ke kila.
6. ʻO nā paipu kila mānoanoa a haʻahaʻa, ʻaʻohe ʻōlinolino metala a he ʻulaʻula māmā a i ʻole like ke kala me ka hao puaʻa. ʻElua kumu. ʻO kekahi, ʻo kāna blank he adobe. ʻO ka lua, ʻaʻole maʻamau ka wela o ka holo ʻana o nā huahana kila hoʻopunipuni a haʻahaʻa. ʻIke ʻia ko lākou wela kila ma ka nānā ʻana. Ma kēiaʻano,ʻaʻole hiki ke hanaʻia ka'ōwili e like me ka'āpana austenite i'ōleloʻia, aʻaʻole kūpono ka hana o ke kila i nā kūlana.
7. ʻO nā iwi ʻaoʻao o nā paipu kila mānoanoa a haʻahaʻa he lahilahi a haʻahaʻa, a ʻike pinepine ʻia lākou me ka hoʻopiha ʻole ʻia. ʻO ke kumu no ka hoʻokō ʻana i kahi hoʻomanawanui maikaʻi ʻole, ʻoi aku ka nui o ka hōʻemi ʻana o nā hala mua o ka huahana i hoʻopau ʻia, ʻoi aku ka liʻiliʻi o ka hao, a ʻaʻole i hoʻopiha ʻia ke ʻano puka.
8. He oval ka pauku kea o ka paipu kila manoanoa. ʻO ke kumu no ka mālama ʻana i nā mea waiwai, hoʻohana ka mea hana i ka nui o ka hōʻemi ʻana i nā ala mua ʻelua o ka wili i hoʻopau ʻia. Hoʻemi nui ʻia ka ikaika o kēia ʻano rebar, a ʻaʻole kūpono i nā ana holoʻokoʻa o ka rebar. nā kūlana.
9. ʻO ka hui ʻana o ke kila he ʻano like, ʻoi aku ka kiʻekiʻe o ka tonnage o ka mīkini ʻili anu, a ʻo ka maka hope o ke poʻo ʻokiʻoki he maʻalahi a maʻemaʻe. Eia nō naʻe, ma muli o ka maikaʻi ʻole o ka waiwai, ʻo ka maka hope o ka ʻoki poʻo o nā mea hoʻopunipuni a me nā mea haʻahaʻa i loaʻa i ke ʻano o ka nalowale ʻana o ka ʻiʻo, ʻo ia hoʻi, ʻaʻohe kūlike a ʻaʻohe luster metala. A no ka liʻiliʻi o nā poʻo o nā huahana i hana ʻia e nā mea hana hoʻopunipuni a haʻahaʻa, ʻike ʻia nā pepeiao nui ma ke poʻo a me ka huelo.
10. ʻO nā mea o nā paipu kila mānoanoa hoʻopunipuni i loko o nā mea haumia he nui, liʻiliʻi ka mānoanoa o ke kila, a ʻaʻole i hoʻomanawanui ka nui, no laila hiki ke kaupaona ʻia a nānā ʻia me ka ʻole o ka vernier caliper. No ka laʻana, no ka rebar 20, ʻōlelo ka maʻamau i ka 5%. Ke 9M ka lōʻihi paʻa, ʻo ke kaumaha o ke koʻokoʻo hoʻokahi he 120 kg. Pono kona kaumaha liʻiliʻi: 120X (l-5%) = 114 kg, ke kaupaona ʻana Inā ʻoi aku ka paona maoli o ka ʻāpana hoʻokahi ma lalo o 114 kilokani, he kila hoʻopunipuni ia no ka mea ʻoi aku ka maikaʻi ʻole o ka 5%. Ma ka ʻōlelo maʻamau, ʻoi aku ka maikaʻi o ka hopena o ke kaupaona hoʻohui pū ʻana, me ka noʻonoʻo nui ʻana i nā pilikia o ka hewa kumulative a me ke kumumanaʻo probability.
11. 'O ke anawaena o loko o na paipu kila mānoanoa a ha'aha'a e loli nui ana ma muli o: 1. He 'ao'ao yin a me yang ka wela kila pa'a'ole. ②. ʻAʻole kūlike ke ʻano o ke kila. ③. Ma muli o nā mea hana maʻemaʻe a me ka ikaika kumu haʻahaʻa, nui ka bounce o ka wili wili. E hoʻololi nui ʻia ke anawaena o loko i loko o ka pule hoʻokahi. ʻO ia ʻano koʻikoʻi like ʻole ma nā kaola kila e alakaʻi maʻalahi i ka haki.
12. ʻO nā hōʻailona kūʻai a me ka paʻi ʻana i nā paipu kila mānoanoa me ka maʻamau.
13. No na lola nui me ke anawaena o 16 a oi no na paipu kila ekolu, aia ka mamao mawaena o na hoailona elua maluna o IM.
14. ʻO nā kīʻaha longitudinal o ka ʻili kila ʻeleʻele he nalu pinepine.
15. ʻAʻohe hana o ka poʻe hana paipu kila mānoanoa a haʻahaʻa, no laila, ua ʻoluʻolu ka ʻeke. He oval na aoao.
