Ngā Āhuatanga Hangarau o te muka basalt, ngā aho tapatapahi, te raima

WHAKAMĀRAMA O TE HUA

He rauemi hanga whānuitia te raima i roto i te hangarau ā-iwi, ā, he pai ōna āhuatanga miihini, engari i te hohonu haere tonu o te whakamahinga o te hangarau miihini, ka āta kitea ngā ngoikoretanga o ōna āhuatanga miihini taketake. Nā te iti o ngā āhuatanga kaha kume, kotahi te whakatekau o te kaha pēhi, ka hua ake he ngāwari te pakaru o ngā mema o te tukanga kume, ka whakaiti tika i te roa o te mau o ngā wāhanga, ka whakawhāiti i te whānuitanga o te whakamahinga o Rauemi Konukuraitis. Hei whakapai ake i ngā āhuatanga mahi hangarau o te raima, me te whakaoti rapanga i roto i te whakamahinga o te raima, kua whakapai ake ngā tohunga i te mahi ongā rauemi raima mō ngā tau maha, ā, kua tutuki ngā hua i ia wāhanga, pērā i te tāpiri i ngā ranunga, te whakarerekē i te ōwehenga whakaranu, te whakapai ake i te tukanga whakaputa me ngā tikanga tiaki.

1. Ngā rauemi whakamātautau me ngā tikanga whakamātautau

I tīpakohia te sima silicate noa P.O 42.5, me te kaha pēhi 28d o te 48.3MPa me te kaha piko 28d o te 8.2MPa. I whakamahia te onepu reo me te modulus pai o te 2.5-2.6 hei kohatu pai, me te kiato kitea o te 1996kg/m3. I whakamahia te kōhatu kuru kua whakarōpūtia tonutia o te 5-27mm hei kohatu matotoru, me te kiato kitea o te 2737kg/m3. I whakamahia te tere whakaiti wai o te 40%. I whakamahia te 40% o te waikawa Sika polycarboxylic tino whai hua hei whakaiti wai. Ko te roa o ngā aho tapatapahi muka pātarati e 30mm te roa, ko te whānui o te monofilament e 15um te whānui, ko te mātotoru e 2.7g/cm3, ko te modulus o te ngāwari e 95-120MPa, ko te kaha kume e 3300-4500MPa, ā, ko te roa i te whati e 2.5-30%.

Ko ngā taunga e tika ana i whakamahia i roto i tēnei whakamātautau e whakaaturia ana i te Ripanga 1. Ka whakatinanahia te whakamātautau pēhanga i runga anō i te Paerewa mō ngā Tikanga Whakamātautau o ngā Āhuatanga Mīhini o te Konukuraiti Noa. Ka whakamahia e te whakamātautau pēhanga he tauira pūtoru 100×100×100mm, e 3 ngā tauira i ia rōpū, he whakamaroke paerewa 28d.

2. The hikoinga

(1) i muri i te tirotiro i te āhua me te ine i te rahi, me horoi tuatahi te wahi whakamātautau hei whakamātautau, kia tika ai ki ahau. Ko te kore taurite o te mata o te tauira e mau ana i te tauira ka eke ki te 100mm, kaua te hapa e neke ake i te 0.5mm, ā, kaua te mata o te tauira me te kore-poutū e neke ake i ngā whakaritenga o te tohu 1 tohu;

(2) kia rite te tuaka tauira o te mīhini whakamātautau ki te pokapū o te pereti pēhanga i raro i te mīhini whakamātautau. Whakatuwheratia te mīhini whakamātautau, ina kati te pereti pēhanga o runga me te wahi whakamātautau, whakatikatikahia te tautoko, kia ōrite te kaha;

(3) kia mau tonu te tukanga uta me te ōrite, ko te tere uta whakamātautau he 12kN / s-18kN / s; (4) tuhia te kawenga mōrahi, kia tika ki te 0.1MPa.

3. Ngā hua whakamātautau me te tātari

E kitea ana i te Ripanga 2, ko te kaha pēhi 7d o te raima me te pikinga o Pātarati Ko ngā āhuatanga o ngā muka he kore e rerekē ki te heke haere, ko te take nui ko te tāpiri o ngā muka basalt ki roto i ngā muka me te sima i hangaia i te atanga hei whakaputa i te mata ngoikore, ā, i te pikinga ake o te nui o te muka e whakaranua ana, ka piki tonu tēnei momo mata ngoikore, nō reira ka heke tonu te kaha pēhitanga tapawhā. Ko te kaha pēhitanga 28d o te raima me te pikinga ake o te horopeta muka basalt e whakaatu ana i te ia o te pikinga tuatahi, kātahi ka heke, ko te take mō tēnei pikinga tuatahi he iti noa te nui o te tāpiringa.ngā muka pātarati he mahi nui tā rātou ki te whakaiti i te whakahekenga o te hanganga o te raima, ā, i te wā anō ka iti ake te pikinga o te kaha 28d i te mata ngoikore, ka piki ake te kaha i roto i te mahi whānui.

4. Hua

Mai i te tirohanga o te kaha pēhitanga pūtoru, ina tae te ranunga muka papara poto ki te 1-1.5% mā te ōrau rōrahi, ko te kaha pēhitanga pūtoru 7d me te 28 o te papara poto muka pātarati ka nui ake te raima ki tētahi taumata ki te whakataurite ki te raima kāore i te whakaranua ki te muka.
