ʻO ka maikaʻi maikaʻi ʻo Drainage Spun Cast Pipe Me ka waha hikiwawe

♦ ʻO ke kaumaha iki, hiki ke hoʻonui ʻia ka lōʻihi o ka paving i kēlā me kēia tona o ka paipu e 20% -30%. 

♦ ʻO ka ʻili me ka ʻole o nā hakahaka a me nā kiko palapa he laumania a nani ke nānā aku. 

♦ ʻO ka mānoanoa o ka pā paipu, ka hana paʻa, ʻoi aku ka kiʻekiʻe o ka tensile a me ka ikaika compressive a me ka hiki i ke kaula-corrosion. 

♦ Ke hoʻopili ʻia a hoʻopaʻa ʻia e nā wili kila kila, maʻalahi ke kūkulu ʻia, mālama ʻia a hoʻololi ʻia ka paipu, mālama nui i ka manpower, nā mea a me ka manawa. 

♦ ʻO kona pilina paʻa paʻa, hiki ke pale i ka hoʻouna kani pono. 

♦ Loaʻa iā ia ka maikaʻi o ka ōlaʻi kūpaʻa a hiki ke oscillated arbitrarily e 15 °, a hiki i kona lateral vibration bending hiki i ± 30.5mm. 

♦ Ma kahi huaʻōlelo, loaʻa i ka huahana nā hana anti-seismic, anti-corrosive, leak-proof a me ke ahi, maʻalahi ke kūkulu ʻia a wehe ʻia, nani a paʻa, ʻoi aku kona ola hana ma mua o 100 mau makahiki, a pili ia i ke kiʻekiʻe- piʻi, mau a me nā hale kī me nā pono ākea maikaʻi.
