Wogula polojekiti akamanditumizira chikalata cha kuchuluka kwa zinthu zomwe zili ndi maenje 200 a nthaka, chinthu chomwe akuyerekeza nthawi zambiri chimakhala mtengo wa unit. Ndikumvetsa chifukwa chake - ndiye nambala yokhayo patsamba. Koma patatha zaka 12 ndikuyang'ana maenje otumizira zinthu m'mapulojekiti oyambira m'makontinenti anayi, ndikukuuzani kuti mtengo wa unit ndi nambala yotsika kwambiri poyerekeza uku. Mtengo wonse wa enje loyambira ndi mulu wa madalaivala asanu - katundu, katundu, ntchito yokhazikitsa, kuyenerera kwa katundu, ndi moyo wautumiki - ndipo konkire imapambana chimodzi mwa izo mu pulogalamu yanthawi zonse yopangira nthaka. Ndiyika manambala enieni a kalasi yonyamula katundu patebulo (kuchokera ku EN 124 ndi magwero a AASHTO), sungani ndalama kukhala zoona popanda kupanga mndandanda wamitengo, ndikukupatsani chida chosankha chomwe ndimagwiritsa ntchito polemba ndemanga yanga.

Kodi Dzenje la Dziko Limachita Chiyani (Ndipo Chifukwa Chake Limasankha Mawerengedwe a Mtengo)

Dzenje la nthaka — lomwe limatchedwanso dzenje loyang'anira kapena chipinda choyezera nthaka — ndi malo olowera pamwamba pa ndodo ya nthaka kapena cholumikizira cha gridi: limateteza cholumikiziracho, limasunga malo oyesera kuti akhale ouma mokwanira kuti atseguke, ndipo limalola gulu lanu lokonza kuti ligwire choyezera pa electrode chaka chilichonse. Dzenje lathu limapereka chithandizo cha nthaka, chitetezo cha mphezi, choletsa kusokonezedwa, komanso choletsa nthaka kuti isasunthike m'malo opangira magetsi, njanji, zomangamanga, migodi, mankhwala, ndi mafakitale — kulikonse komwe kulumikizana kwa nthaka kumafunika kuyang'aniridwa nthawi yomweyo. Ndikugogomezera ntchitoyi chifukwa imakonza zofunikira pa katundu: malo oyesera nthaka ali m'mphepete mwa msewu, m'mbali mwa msewu, pakona ya bwalo, kapena m'mbali mwa msewu — malo oyenda pansi. Sindinawonepo munthu atakhala mumsewu wa galimoto yayikulu.Popeza ntchito ya dzenje ndi kupeza ndi kuteteza osati kunyamula katundu wopangidwa ndi kapangidwe kake, gulu la katundu lomwe mumafunikira nthawi zambiri ndi A15 kapena B125 — ndipo mfundo imodzi yokhayo imasintha kufananiza kwa mtengo wonse wa polima ndi konkriti.

Manambala a katundu, kuchokera ku miyezo yokha

Ndimatchula magulu onyamula katundu kuchokera ku magwero oyambira chifukwa "ntchito yolemera" sikutanthauza chilichonse popanda nambala. Ndimatengera maguluwo molunjika kuchokera ku European framework, EN 124-1:2015, yomwe imawatanthauzira ndi mayeso a katundu: A15 pa 15 kN pamadera omwe amagwiritsidwa ntchito ndi oyenda pansi ndi okwera njinga okha, B125 pa 125 kN pamayendedwe oyenda pansi ndi malo oimika magalimoto, C250 pa 250 kN panjira zolowera m'mphepete mwa msewu, ndi D400 pa 400 kN pamayendedwe onyamula katundu. Gawo lapadera la thermoplastics,EN 124-6:2015 ya zophimba za PP, PE, ndi PVC-U, imagwira ntchito pa ma class A15 ndi B125 ndipo imafuna kuti gawo lililonse lipangidwe kuchokera ku chinthu chimodzi, chokhazikika ndi UV. Ndimasintha mawu ku North America: paBuku lotsogolera la wopanga EJ lowunikira kuchuluka kwa katundu, magalimoto osagwiritsa ntchito magalimoto amatha kunyamula katundu wolemera mpaka 2,500 lb, katundu wopepuka umakwana 2,500–16,000 lb, ndipo chizindikiro chodziwika bwino cha AASHTO H-20 chimatanthauza katundu wa gudumu la 16,000 lb wokhala ndi mayeso oletsa 40,000 lb pa pad ya 9×9 inchi. Ndimagwiritsa ntchito mapu osankha magalimoto ndi bungwe la malonda la UK.Buku lotsogolera la BPF Pipes Group la zipinda zowunikira pulasitiki: Malo oyenda pansi a gulu loyamba amafunika A15 (kuyesa kwa 15 kN), malo oyenda pansi a gulu lachiwiri ndi malo oimika magalimoto amafunika B125 (kuyesa kwa 125 kN), ndi kalasi ya A35 pakati pa malo olowera magalimoto achinsinsi.

Kumene konkriti ikufunikadi

Ine ndine manejala wogulitsa wa opanga ma polymer pit ndikukuuzani nthawi yogulira konkire, choncho werengani izi moona mtima. Malangizo a mtengo wa boma la 2024 omwe aperekedwa ndiLCS Construction ya pulojekiti ya Berkeleyikuwonetsa momwe mainjiniya amagawira zipangizo: mabowo ogwirira ntchito ndi mabokosi m'misewu ndi njira zoyendera magalimoto mwadala ziyenera kukhala konkire yokonzedwa kale ku AASHTO H-20; malo olowera magalimoto ndi oimika magalimoto omwe nthawi zina magalimoto olemera osachita dala akhoza kukhala konkire ya polymer ku SCTE 77 Tier 15; malo oyenda pansi pa msewu amatenga Tier 8; ndipo malo oyenda pansi okha ndi omwe angagwiritse ntchito mayunitsi a fiberglass oyesedwa kufika pa 3,000 lbf (13,345 N). Ndikufuna kuti muzindikire momwe zinthu zilili: zinthuzo zimatsatira bokosi lonyamula katundu, ndipo bokosi lonyamula katundu limatsatira magalimoto. Ngati dzenje lanu la nthaka lili pamalo omwe magalimoto amayendetsa mwadala, ndikukuuzani kuti mugule konkire yokonzedwa kale - yathu si chinthu choyenera ndipo palibe wina aliyense amene ali ndi chipangizo cha polymer.

Dalaivala 1 — Mtengo wa Unit: Nambala Imodzi Yoyerekeza ndi Aliyense

Apa ndi pomwe ndimasunga lonjezo langa loti sindipanga mndandanda wamitengo: mitengo ya zinthu imasinthasintha malinga ndi misika ya resin, misika ya simenti, kuchuluka kwa maoda, ndi komwe ndikupita, kotero ndalama iliyonse yomwe ndasindikiza ingakhale yotayika mkati mwa kotala. Ndimauza ogula zomwe sizisuntha: kapangidwe kake. Ndimaona ma polima opangidwa ndi zinthu ndi maenje ang'onoang'ono a konkriti omwe ali kale m'dera lomwelo la mtengo wa fakitale - nthawi zina konkriti imatsika mtengo pa kuchuluka kwa zinthu, nthawi zina polima imatsika mtengo pa kukhazikika kwa zinthu. Ndatchula zonse kuchokera ku fakitale yomweyi (mzere wathu wa AF-N0658 uli ndi mitundu ya PVC ndi konkriti), ndipo ndimauza ogula chinthu chomwecho nthawi zonse: mtengo wa fakitale ndi chipata ndi wozungulira chimodzi mwa zisanu, ndipo kuzungulira ndiko komwe kuli kofunikira kwambiri pa maoda otumiza kunja.

Dalaivala 2 — Katundu: Kumene Konkire Ikutaya Oda Yotumizira Kunja

Ndimaona kulemera ngati tsogolo la zinthu. Dzenje la konkire lopangidwa kale lomwe lili ndi mphamvu yofanana limalemera kangapo kuposa kulemera kwa dziwe la polima lopangidwa - ndiko kuti, fizikisi, osati malonda, ndipo limadutsa mu gawo lililonse la katundu: mayunitsi ochepa pa pallet, ma pallet ochepa pa chidebe, katundu wokwera panyanja pa unit imodzi, magalimoto olemera kwambiri mkati mwa dziko, ndi malire ogwirira ntchito pamanja mbali zonse ziwiri. Ma polima athu amatumizidwa okhala ndi zomangira zamkati, makatoni, ndi ma pallet kuchokera ku doko la Ningbo kapena Shanghai - dongosolo lolongedza lopangidwa mozungulira kulemera kopepuka - ndipo pa dongosolo la polojekiti ya ma pit 200 mpaka 500, kusunga katundu kokha nthawi zonse kumaposa kusiyana kulikonse kwa mtengo wa fakitale ndi chipata.Popeza katundu wa panyanja amalipiritsa pa voliyumu ndi mabulaketi olemera m'malo mwa mtengo wa chinthu, kutumiza katundu wolemera padziko lonse lapansi ndiyo njira yachangu kwambiri yowonongera phindu lake pamtengo.Ndimayesa masamu awa pa mawu enieni nthawi zonse, ndichifukwa chake funso langa loyamba kwa wogula poyerekeza mtengo silikhala lakuti "adalemba mtengo wanji" koma "chinthu chimodzi chimalemera chiyani."

Dalaivala 3 — Kukhazikitsa: Munthu M'modzi Mosiyana ndi Ogwira Ntchito

Ndimasiya kuchita zinthu mosamala pamalopo: kufananiza sikuli pafupi. Ndimafotokoza za kuyika kwa polima motere: kukumba thumba, kuyika dzenje pamwamba pa elekitirodi, kupanga kulumikizana, kudzaza, kumaliza — wantchito m'modzi, zida zamanja, osadikira. Ndimaona kuyika konkire kukuwonjezera kukweza (manja ena osachepera, thandizo la makina kwambiri), gawo lokonzekera la zofunda, mipando yosamala kuti mupewe kuthyola zinthu zomwe zimaswa mkombero, komanso kusakhululuka ngati dzenjelo litagwa mokhota. Ndimachulukitsa kusiyana kwa ntchito poyika dzenje la 200 ndipo kuyika kumakhala mtengo waukulu kwambiri womwe ungawongoleredwe mu projekitiyi.Popeza ntchito yokhazikitsa imafanana ndi kuchuluka kwa maenje pomwe ntchito ya uinjiniya siili yofanana, ubwino wokhazikitsa polima pa unit iliyonse umakula kwambiri pamene polojekitiyo ikukula.Mawu athu a pa datasheet ndi osavuta kuwadziwa — “kukhazikitsa kosavuta, kotsika mtengo” — ndipo amapulumuka ngakhale atakumana ndi malo enieni ogwirira ntchito.

Dalaivala 4 — Kuyenerera kwa Kulemera: Siyani Kulipira Mphamvu Yomwe Simungagwiritse Ntchito

Ndikuona dalaivala uyu akuchepetsa mtengo wa polymer m'njira yomwe ogula sakonda kuigula. Ngati malo anu oyesera ali pafupi ndi oyenda pansi, mfundo yolondola ndi A15; malo oimika magalimoto, B125. EN 124-6 ilipo kuti itsimikizire zophimba za thermoplastic za magulu awiriwa, ndi UV stabilization yofunikira. Ndimatcha ubwino wa konkriti — mphamvu ya D400 carriageway ikalimbikitsidwa ndi chitsulo — mphamvu yomwe simungagwiritse ntchito pamalo oyesera pansi, ndipo ndimakana kulola ogula kulipira. Dongosololi limagwira ntchito mbali zonse ziwiri: ngati dzenje limodzi mu kapangidwe kanu lili panjira yotumizira, dzenje limenelo — ndipo dzenje limenelo lokha — limapeza chivundikiro chovomerezeka. Ndasunga ogula ndalama zenizeni pongogawa oda ya ma-pit 200 m'mayunitsi a polymer 195 ndi mayunitsi asanu ovomerezedwa pambuyo poyang'ana dongosolo lawo la magalimoto.

Dalaivala 5 — Moyo wa Utumiki: Mtengo Womwe Umabwera mu Chaka 12

Ndaphunzira kuti zomangamanga zobisika zimalephera mwakachetechete. Ndimaona maenje a konkriti akusweka pansi pa kayendedwe ka kuzizira ndi kusungunuka, malo otayira pomwe ma chloride amafika pa reinforcement, ndikutaya chivindikiro chawo chachitsulo kapena chitsulo kuti chizimiririke mu dothi lonyowa komanso lolimba la mankhwala komwe makina oyambira amakumana. Dzenje lokhazikika la UV-stabilized PP, PE, kapena PVC-U lilibe reinforcement kuti lizimiririke, lilibe simenti yoti lizimiririke, ndipo - malinga ndi malamulo a EN 124-6's material - phukusi la UV lolamulidwa la gawo lomwe lawonekera. Timayesa mzere wathu wa polymer earth pit pa zaka zoposa 50 za moyo wa ntchito, ndipo ndimaona kuti izi ndizoyenera kuti chipangizocho chikhale pamalo oyenera.Popeza dzenje la nthaka limateteza chinthu chimodzi, muyenera kugwiritsa ntchito nthawi yonse ya dongosololi - kulumikizana kwa electrode - dzenje lomwe limalephera misonkho ya chaka cha 12 chaka chilichonse chotsala cha dongosolo lokhazikitsa pansi ndi ntchito ina yosinthira.

Ndimaona kuti kusintha kwa malo osungiramo zinthu ndikofunika kwambiri monga kufukula, dzenje latsopano, kufufuza komwe kungagwirizanitsidwenso, komanso kuyendera gulu; kupewa kusintha kwa malo osungiramo zinthu ndikofunika kwambiri kuposa mkangano uliwonse wokhudza mitengo ya fakitale.
