He aha ngā mea kei roto i te whakamātautau kounga o te tarutaru horihori?E rua ngā paerewa matua mō te whakamātautau kounga o te tarutaru horihori, arā, ko ngā paerewa kounga hua tarutaru horihori me ngā paerewa kounga o te papa whariki tarutaru horihori. Kei roto i ngā paerewa hua ko ngā paerewa kounga muka tarutaru horihori me ngā paerewa tirotiro ā-tinana o te tarutaru horihori; kei roto i ngā paerewa o te papa ko te papatahi o te papa, te piko, te whakahaere rahi o te papa me ētahi atu paerewa.
Ngā paerewa tirotiro kounga hua: He mea hanga ngā miro tarutaru horihori ki ngā rauemi PP, PE rānei. Me tirotirohia ngā miro tarutaru e ngā tari whakamātautau tino pakari. Me whiwhi ngā kaihanga tarutaru horihori i te tiwhikete tiaki ahi taumata tuarua a SGS, te tiwhikete matū paitini me te kino, te ārai-waikura, te tiwhikete ātete-mau, me ētahi atu; i te wa ano, ka pā te piripiri e whakamahia ana i raro ki te kounga o te tarutaru horihori, ā, me whiwhi te piripiri i ngā tiwhikete tiaki taiao me te haumaru.
Ngā paerewa tirotiro kounga ā-tinana: arā, te totoro o te muka tarutaru horihori, te whakamātautau ārai-pakeketanga, te tae o te tarutaru horihori me ētahi atu paerewa whakamātautau tarutaru horihori. Kaua e iti iho i te 15% te roa o te kume o ngā miro tarutaru horihori i te taha roa, kaua hoki e iti iho i te 8% te roa o te kume; me 30KN/m te iti rawa o te paerewa kaha haehae o te tarutaru horihori i te taha roa, kaua hoki e iti iho i te 25KN/m i te taha whakawhiti; Ka tutuki i ngā paerewa te tere roa me te kaha haehae o te tarutaru, ā, ka whakarei ake i te kounga o te tarutaru.
Ngā paerewa whakamātautau tae: Me whakamātautau te tae o te tarutaru mō te ātete ki te waikawa whanariki. Tīpakohia he nui e tika ana o te tauira tarutaru horihori, ka rumakina ki te 80% waikawa whanariki mō ngā rā e 3. I muri i ngā rā e 3, tirohia te tae o te tarutaru. Mena kāore he huringa o te tae o te tarutaru, ka whakatauhia kua tutuki te tae o te tarutaru horihori i ngā paerewa kounga o te tarutaru horihori.
Hei tāpiritanga, me whakamātautau te pakeketanga o te tarutaru horihori. Whai muri i te whakamātautau pakeketanga, ka whakatauhia te kaha kume o te tarutaru kia 16 MPa te iti rawa i te taha roa, kaua hoki e iti iho i te 8 MPa i te taha whakamuri; kaua hoki e iti iho i te 25 KN/m te kaha haehae i te taha roa, me te 20 KN/m i te taha whakamuri. m. I taua wā anō, me whai paerewa ārai ahi hoki te kounga o te tarutaru horihori. Mō te ārai ahi, tīpakohia he nui e tika ana o ngā tauira tarutaru, ka whakakīia ki te onepu pai i te 25–80 kg/㎡ hei whakamātautau. Mena kei roto i te 5 cm te whānui o te wāhi mura, he taumata 1, ā, he ātete ahi te tarutaru horihori. Kei te paerewa te ira tangata.
Ko te paerewa mō te tirotiro kounga o te papa whenua ko te whakahaere i te papatahi o te papa ki te 10mm, me te whakamahi i te aho iti 3m hei ine hei karo i ngā hapa nui; i te wā e papa ana i ngā papa tarutaru, me whakarite kia whakahaeretia te piko o te papa i roto i te 1%, ā, me ine ki te taumata; me whakahaere te piko, kia pai ai te rere o te wai i roto i te papa tarutaru. I taua wā anō, ka whakahaeretia te hapa rahi o te roa me te whānui o te papa tarutaru horihori ki te 10 mm. Whakamahia he rūri hei ine, ā, kia iti rawa te hapa.
Ka taea anake te whakakotahi i ngā hua tarutaru horihori ki te papa kua wharikitia mā te mātau ki ia tawhā.Hua tarutaru horihoriHe tino whai hua ngā tohu, ā, e tutuki ana i ngā paerewa. Mēnā kāore ngā whakaritenga mō te whakatakoto papa whenua e tutuki ana i ngā paerewa, e kore e taea e te tarutaru horihori te whakaatu i tōna uara whakamahinga pai rawa atu. Nō reira, me whakauru te kounga hua me ngā paerewa o te papa whenua ki ngā paerewa kounga teitei mō te tarutaru horihori, ā, he mea nui rawa atu ēnei e rua.
