ʻO ka GDD Fire Rated Calcium Silicate Board no ka hoʻopaʻa ʻana i ka tunnel

1, ahi hana: homogeneous mea, mea non-combustible papa A1, pā mānoanoa o 10mm / 24mm hiki ke hoʻokō i ka RABT ahi palena maʻamau koi o ka tunnel luna.
2, pā māmā: ʻo ka mānoanoa maloʻo ma kahi o 900kg/m3 wale nō, he mea palekana palekana.
3, kū'ē i ka wā: ma ka laina me ka waikawa, ka alkali, ka wela, ka paʻakai paʻakai, ka hau a me ka hoʻoheheʻe ʻana.
4, hoʻokō i ka lōʻihi o ka oi ma mua o 20 makahiki o ka lawelawe ola.
5. Hoʻopaʻa leo Seismic: paʻa paʻa ka pā ma muli o nā wili paʻa kūikawā.Aia ka piston ma lalo o ke kaomi makani, ʻaʻole e wehe ʻia ma muli o ke ʻano o ka pā
ʻO ka hoʻokumu ʻana o nā micropores, no laila he hopena kani maikaʻi.
6, palekana kaiapuni: hoʻohana ka pā i nā mea waiwai inorganic, ma hope o ke kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe ka hoʻōla ʻana i ka mahu, mālama ʻia, ʻaʻohe asbestos a me nā mea ʻino radioactive.
7, kūkulu kaiapuni: ke kūkulu ʻana i ka mahana o ke kaiapuni, humidity, ventilation me ka ʻole o nā koi kūikawā, ka hana maloʻo, ʻaʻohe pollution pōʻino i ke kaiapuni.
8, wikiwiki ke kūkulu ʻana: hoʻopau ʻia ka hana hoʻokahi manawa, ʻaʻohe pono e hana hou i ka hana i hope a i waho, ʻaʻohe pono no ka hoʻonani lua, a ʻo ka wikiwiki ka 8-10 mau manawa wikiwiki ma mua o ka uhi ahi.
9, ʻoi aku ka maikaʻi: ʻo ka uhi ʻana i ke ahi nā huahana ahi ahi mua i ka makahiki 1980, no ka mea, pono e hoʻomākaukau ʻia ka uhi ahi ahi e hoʻomākaukau ʻia a hoʻoheheʻe ʻia ma kahi, he nui.
ʻO ka nui o ka hana bricklayer, no laila aia ka pilikia o ka instability o ka huahana a me ke kumukūʻai hana kiʻekiʻe, a ʻo GDD tunnel fire prevention board kahi huahana hale paʻa.
ʻO ka pōmaikaʻi i ka paʻa o ka huahana, ʻoi aku ka maikaʻi ma mua o ka pena, kūpono.
