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

1, ahi hana: homogeneous mea, mea non-combustible A1 papa mea, pā mānoanoa o 10mm / 24mm hiki ke hoʻokō i ka RABT palena ahi koi maʻamau o ka tunnel luna.
2, pā māmā: ʻo ka mānoanoa maloʻo ma kahi o 900kg/m3, 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. Ke kani leo Seismic: ua 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, ka mālama ʻana i ke kaiapuni: hoʻohana ka pā i nā mea waiwai inorganic, ma hope o ke kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe ka hoʻōla ʻana i ka mahu, mālama, 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 he 8-10 mau manawa ʻoi aku ka wikiwiki ma mua o ka uhi ahi.
9, ʻoi aku ka maikaʻi: ʻo ka uhi ʻana i ke ahi ka huahana pale ahi mua i ka makahiki 1980, no ka mea, pono ka hoʻomākaukau ʻana i ka uhi ahi ahi e hoʻomākaukau ʻia a hoʻoheheʻe ʻia ma ka wahi, nui ia.
ʻO ka nui o ka hana bricklayer, no laila aia ka pilikia o ka instability 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.
