Iyo umuguzi w’umushinga anyoherereje fagitire y’ingano irimo imyobo 200 y’ubutaka, ikintu bagereranya hafi ya cyose ni cyo giciro cy’imigabane. Ndumva impamvu - ni yo nomero yonyine iri ku ipaji. Ariko nyuma y’imyaka 12 yo kugenzura imyobo mu mishinga yo gufunga ubutaka ku migabane ine, ndakubwira ko igiciro cy’imigabane ari cyo giciro gito cyane muri uku kugereranya. Igiciro cyose cy’imyobo y’ubutaka gishyirwamo ni umurundo w’ibinyabiziga bitanu - ibicuruzwa, imizigo, imirimo yo kuyishyiraho, ubushobozi bwo kuyishyiramo, n’igihe cyo kuyikoresha - kandi sima itsindira kimwe muri byo mu buryo busanzwe bwo kuyishyiraho. Nzashyira imibare nyayo y’ubwoko bw’imyobo ku meza (kuva kuri EN 124 na AASHTO), nkomeze kuvugisha ukuri ku ruhande rw’amafaranga ntahimbye urutonde rw’ibiciro, kandi nguhaye igikoresho cyo gufata ibyemezo nkoresha mu isuzuma ryanjye bwite.

Icyo Icyobo cy'Isi Gikora Mu by'ukuri (N'impamvu Ibyo Bigena Imibare y'Ikiguzi)

Icyobo cy'ubutaka - cyitwa kandi icyobo cyo kugenzura cyangwa icyumba cyo gucukuramo ubutaka - ni aho umuntu yinjira hejuru y'inkoni yo hasi cyangwa aho icyuma gihurira: kirinda igice cyo hasi, gikomeza aho ikizamini cyumye bihagije kugira ngo gifunguke, kandi kikemerera abakozi bawe bashinzwe kubungabunga icyuma gipima kuri electrode buri mwaka. Ibyobo byacu bitanga ibikoresho byo gucukura hasi, kurinda inkuba, kurwanya ingaruka mbi, no kurwanya ihindagurika ry'ubutaka mu mashanyarazi, gari ya moshi, ubwubatsi, ubucukuzi bw'amabuye y'agaciro, imiti n'inganda - ahantu hose igikoresho cyo gucukura ubutaka gikeneye gukorerwa igenzura ryihuse. Ndashimangira imikorere kuko ikosora ibisabwa ku mutwaro: aho ikizamini cyo gucukura hasi kiri ku nkengero z'umuhanda, ku ruhande rw'abanyamaguru, mu mfuruka y'ubusitani, cyangwa ku gice cy'abanyamaguru giteye neza. Sinigeze mbona umuntu yicaye mu muhanda w'ikamyo.Kubera ko akazi k'icyobo ari ukwinjira no kurinda aho kuba ukwikorera imizigo mu buryo bw'imiterere, icyiciro cy'imizigo ukeneye mu by'ukuri ni A15 cyangwa B125 - kandi icyo kintu kimwe gihindura igereranya ry'ibiciro bya polimeri ugereranije na beto.

Imibare y'imitwaro, uhereye ku bipimo ubwabyo

Nsubiramo amasomo y’imitwaro mu masoko y’ibanze kuko "umutwaro ukomeye" ntacyo bivuze udafite umubare. Nfata amasomo mu buryo butaziguye uhereye ku murongo w’Uburayi, EN 124-1:2015, usobanura imitwaro y’igerageza: A15 kuri 15 kN ku bice bikoreshwa n’abanyamaguru n’abanyamagare gusa, B125 kuri 125 kN ku nzira z’abanyamaguru n’aho baparika imodoka, C250 kuri 250 kN ku miyoboro yo ku nkengero z’umuhanda, na D400 kuri 400 kN ku nzira z’imodoka. Igice cyihariye cy’ibikoresho bya thermoplastic,EN 124-6:2015 ku bifuniko bya PP, PE, na PVC-U, ikoreshwa ku bikoresho byo mu rwego rwa A15 na B125 kandi isaba ko buri gice cyose gikorwa mu bikoresho bimwe, bifite UV-stabilized. Nhindura amagambo muri Amerika ya Ruguru: kuriUbuyobozi bw'igenzura ry'umutwaro bwa EJ bw'uruganda, ibyuma bidakoresha amashanyarazi bipima ibiro bigera kuri 2.500, umutwaro woroheje upima ibiro 2.500–16.000, kandi amanota azwi cyane ya AASHTO H-20 bivuze ko umutwaro w'ibiziga bya 16.000 hamwe n'ikizamini cya 40.000 lb kidakoreshwa kuri pad ya santimetero 9 × 9. Nateguye imyitozo yo guhitamo hamwe n'ikigo cy'ubucuruzi cy'Ubwongereza.Ubuyobozi bwa BPF Pipes Group ku byumba byo kugenzura pulasitiki: Agace k'abanyamaguru mu itsinda rya mbere gakeneye A15 (ikizamini cya 15 kN), inzira z'abanyamaguru mu itsinda rya kabiri n'aho baparika imodoka bikeneye B125 (ikizamini cya 125 kN), hamwe n'ishuri rya A35 hagati y'inzira z'abantu ku giti cyabo.

Aho beto ikenewe by'ukuri

Ndi umuyobozi ushinzwe kugurisha mu nganda zikora ibintu bikozwe muri polima, ndababwiza igihe cyo kugura sima, bityo soma ibi mu buryo buboneye. Ibisobanuro by'ipiganwa rya 2024 ryatanzwe naLCS Construction ku mushinga wa Berkeleyigaragaza uburyo injeniyeri zitanga ibikoresho: imyobo n'amasanduku mu mihanda n'inzira z'imodoka zigomba kuba zarateguwe mbere ya sima kuri AASHTO H-20; ahantu ho kunyura no guparika imodoka ziremereye rimwe na rimwe hashobora kuba hakozwe sima ya polymer kuri SCTE 77 Tier 15; ahantu ho kunyura abantu ku muhanda hafatwa Tier 8; kandi ahantu hagenewe abanyamaguru gusa hashobora gukoreshwa ibikoresho bya fiberglass byapimwe kugeza kuri 3,000 lbf (13,345 N). Ndashaka ko ureba imiterere: ibikoresho bikurikirana aho imizigo ishyirwa, naho aho imizigo ishyirwa hagakurikira aho imodoka zitwara. Niba ahantu hari ubutaka bwawe haherereye aho amakamyo atwara nkana, ndakubwira kugura sima yagenwe mbere yakoreshejwe - iyacu si yo ikwiye kandi nta n'undi muntu ukoresha polymer.

Umushoferi 1 — Igiciro cy'igice: Umubare umwe abantu bose bagereranya

Dore igice aho nubahiriza isezerano ryanjye ryo kudahimba urutonde rw'ibiciro: ibiciro by'ibicuruzwa bigenda bihinduka bitewe n'amasoko ya resin, amasoko ya sima, ingano y'ibicuruzwa, n'aho bijya, bityo amafaranga yose nacapye azaba asigaye mu gihembwe kimwe cya kane. Mbwira abaguzi ibitagenda: imiterere. Mbona polymer ikoze mu buryo bwa polymer n'ibinogo bito bya sima byateguwe biri mu gace kamwe kanini gafite igiciro cy'uruganda - sima rimwe na rimwe igwa hasi bitewe n'ingano y'ibicuruzwa, polymer rimwe na rimwe ikaba hasi bitewe n'imiterere yayo. Navuze byombi bivuye mu ruganda rumwe (umurongo wacu wa AF-N0658 ukoresha ubwoko bwa PVC na sima), kandi mbwira abaguzi ikintu kimwe buri gihe: igiciro cy'uruganda ni kimwe cya mbere muri bitanu, kandi ni cyo kintu cy'ingenzi cyane ku bicuruzwa byoherezwa mu mahanga.

Umushoferi wa 2 — Umuzigo: Aho Beto Itakaje Itegeko ryo Kohereza mu mahanga

Mfata uburemere nk'iherezo mu bijyanye n'ibikoresho. Icyobo cya sima cyakozwe mbere gifite ubushobozi bungana gipima inshuro nyinshi icyobo cya polymer cyakozwe - ni ukuvuga fiziki, ntabwo ari ubucuruzi, kandi gica mu ntambwe yose y'imizigo: ibice bike kuri palati imwe, palati nke kuri kontineri imwe, imizigo myinshi yo mu nyanja kuri buri gice, amakamyo akomeye yo mu gihugu, n'imipaka yo gukoresha intoki ku mpande zombi. Ibigega byacu bya polymer byoherezwa mu bipaki by'imbere, amakarito, n'amapalati bivuye ku cyambu cya Ningbo cyangwa Shanghai - gahunda yo gupakira yagenewe uburemere bworoheje - kandi ku mushinga usanzwe w'ibigega 200 kugeza kuri 500, kuzigama imizigo byonyine biruta itandukaniro ry'ibiciro by'uruganda n'irembo.Kubera ko ibicuruzwa byo mu mazi byishyurwa ku bwinshi n'ibipimo by'uburemere aho kwishyurwa ku gaciro k'ibicuruzwa, kohereza ibicuruzwa biremereye ku isi ni bwo buryo bwihuse bwo gusenya inyungu y'ibiciro byabyo.Ndakoresha iyi mibare ku ibiciro nyabyo buri gihe, niyo mpamvu ikibazo cyanjye cya mbere ku muguzi ugereranya ikiguzi kitaba “igiciro yaguze” ahubwo kiba “igipimo kimwe gipima iki.”

Umushoferi wa 3 — Gushyiraho: Umuntu umwe ugereranije n'abakozi

Ndareka kuba umuhanga aho hantu: kugereranya ntabwo ari hafi. Nsobanura ko polimeri ishyirwamo: gucukura umufuka, gushyira umwobo hejuru y'amashanyarazi, guhuza, gusubiza inyuma, kurangiza — umukozi umwe, ibikoresho by'amaboko, nta gutegereza. Ndeba ko gushyiraho sima bongeraho guterura (amaboko abiri nibura, ubufasha bwa mekanike mu gihe kibi), urwego rw'ibitanda rwateguwe, kwicara witonze kugira ngo wirinde imitwaro y'ingingo ivuna umugongo, kandi nta mbabazi niba umwobo uguye mu kidatuza. Ngwiza itandukaniro ry'umurimo mu gusohora ibicanwa 200 kandi gushyiraho biba ikiguzi kinini gishobora kugenzurwa muri uyu mushinga.Kubera ko abakozi bo gushyiraho ibikoresho bangana ku buryo bugororotse n'umubare w'ibinogo mu gihe abakozi bo mu ikoranabuhanga batabikora, inyungu yo gushyiraho ibikoresho bya polymer kuri buri gice irushaho gukomera uko umushinga ugenda ukura.Interuro yacu bwite kuri ibi irasobanutse neza — “byoroshye kuyishyiraho, ihendutse” — kandi irakomeza guhura n’imbuga z’akazi nyazo.

Umushoferi wa 4 — Ingano y'umuzigo: Reka kwishyura imbaraga udashobora gukoresha

Ndabona uyu mushoferi arenga ku giciro cya polymer mu buryo abaguzi badakunze kugiha ibiciro. Niba aho upimira hari ahantu hagenewe abanyamaguru, ibisobanuro bikwiye ni A15; aho uparika imodoka, B125. EN 124-6 ihari kugira ngo yemeze neza ibifuniko bya thermoplastic kuri ibyo byiciro bibiri, hamwe n'ubudahangarwa bwa UV. Nita inyungu ya beto - ubushobozi bwa D400 mu nzira iyo icyuma gikomejwe - imbaraga udashobora gukoresha aho upimira, kandi nanze ko abaguzi bayishyura. Icyitonderwa gikora mu buryo bwombi: niba hari icyobo kimwe mu gishushanyo cyawe kiri mu nzira yo gutwara, icyo cyobo - kandi icyo cyobo gusa - kibona igifuniko gifite agaciro. Nazigamiye abaguzi amafaranga nyayo gusa binyuze mu kugabanya itegeko rya 200-pit mo 195 polymer utwuma n'utwuma 5 twakosowe nyuma yo kureba gahunda yabo y'umuhanda.

Umushoferi wa 5 — Ubuzima bwa serivisi: Ikiguzi kigera mu mwaka wa 12

Namenye ko ibikorwa remezo bitwikiriwe bicika bucece. Mbona ibyobo bya sima bicikamo ibice bitewe n’imikorere y’ubukonje, aho chloride igera ku nkunga, kandi igatakaza imipfundikizo yayo y’icyuma cyangwa icyuma ikarangirira mu butaka butose kandi bushyushye aho sisitemu zo gusimbuza ubutaka zihurizwa. Icyobo cya PP, PE, cyangwa PVC-U gifite UV-stabilized nta nkunga yo kwangirika, nta sima ifite matrix yo kwangirika, kandi - nk'uko amategeko ya EN 124-6 abivuga - ni paki ya UV itegetswe ku gice cyagaragaye. Dushyira mu gaciro umurongo wacu w’ibitugu bya polymer ku myaka irenga 50 y’ubuzima, kandi ndabifata nk'ibirinda ko ibikoresho bishyirwa mu mwanya wabyo.Kubera ko icyobo cy'ubutaka kirinda igice kimwe, ugomba kubona ubuzima bwose bwa sisitemu - itumanaho rya electrode - icyobo kinanirwa mu misoro yo mu mwaka wa 12 buri mwaka usigaye wa sisitemu yo gusimbuza ubutaka hamwe n'akazi ko gusimbuza.

Ntekereza ko gusimbuza ari ugucukura, icyobo gishya, kugenzura aho kongera guhuza amazi, no gusura abakozi; kwirinda igihe kimwe cyo gusimbuza bigira agaciro kurusha impaka zose zijyanye n'ibiciro by'irembo ry'uruganda.

Ikiyobo cy'ubutaka cya polymer vs beto: Imbonerahamwe yuzuye yo kugereranya

Igikoresho cyo gufata ibyemezo nkoresha mu gutanga ibitekerezo byanjye bwite

Subiza ibibazo bine ku mushinga wawe maze logique yikorere. Nabikoze mu buryo bwo kugenzura imikoranire hepfo - ni nako nkurikirana mu guhamagara abantu.

Ibyo Twubaka n'uko Tubyohereza

Ibyacuicyobo cyo kugenzura ibikoresho bya pulasitikiumurongo (model AF-N0658) ukozwe mu bwoko bwa PVC cyangwa beto — ndabigumana byombi kuko gutanga ibikoresho by’ukuri bivuze gutanga ibikoresho bikwiye kuri buri gace — byahawe agaciro k’imyaka irenga 50 munsi y’ubutaka, hamwe na serivisi ya OEM na ODM ku bipimo byihariye by’umushinga n’ikirango. Ku baguzi bubaka sisitemu zose zo kwinjiramo, guhuzaibipfukisho by'ubutaka by'icyumba cya pulasitiki kininigutwara igishushanyo mbonera cy'urukuta rw'imitwaro, kandiIgipfukisho cy'ingomero ya PVC ifite impande enyeifunga ahantu hanini ho kugenzura; umuryango wose wicaye munsi y'inzu yacuicyiciro cy'icyobo cy'ubutakaDukora umusaruro ku bice 50.000 ku kwezi dukurikije ISO 9001 dukoresheje gahunda yacu ya QC ifite amarembo atandatu — IQC, IPQC, igenzura rya mbere, ikorwa ry’ibintu byinshi, OQC, na FQC — kandi buri gikoresho gishyirwa mu ipaki y’imbere hamwe n’amakarito hamwe n’amapaleti, ashyizwe mu makontenari i Shanghai cyangwa Ningbo. Dufata igihe gisanzwe cyo gutanga umusaruro ku minsi 10 ku bice 100 bya mbere, kandi nganira ku ngano y’ibicuruzwa ugereranije na gahunda y’umushinga.

Inyandiko zo mu murima: Amakosa yo gutanga amasoko ndeba abaguzi basubiramo

Ndahindura imiterere itatu inyuma y’ibyemezo bihenze cyane byo mu mwobo w’ubutaka. Imiterere yanjye ya mbere ni ugusobanura ibintu byinshi cyane: fagitire yose y’ingano yandikwa ku muhanda mubi cyane, bityo ibyobo 200 bifite igipimo cy’umutwaro bitanu muri byo bikenewe. Imiterere yanjye ya kabiri ni ubuhumyi bw’imizigo: urupapuro rwo kugereranya ruhagarara ku irembo ry’uruganda, maze fagitire y’ibigega irantungurwa. Imiterere yanjye ya gatatu ni ukwibagirwa ubuzima bwose: uburyo buhendutse bwo kugura buhabwa agaciro ko kuramba budafite mu butaka bukaze, kandi inzira yo gusimbuza igwa ku ngengo y’imari y’undi muntu nyuma y’imyaka icumi.Kubera ko ibinogo by'ubutaka ari ikintu gito gifite umuvuduko munini - buri kizamini cyo gupima ubutaka gishingira kuri byo mu gihe cy'imyaka ibarirwa muri za mirongo - iminota itanu ikoreshwa mu gushushanya igishushanyo mbonera cy'aho hantu ni intambwe ifite agaciro kanini mu itangwa ry'amasoko yose.
