Pamene ntchito yomanga zomangamanga ikulowa mu gawo la chitukuko chapamwamba, kugwiritsa ntchito zipangizo zopangira geosynthetic m'magawo monga misewu ikuluikulu, kusamalira madzi, ndi kuteteza chilengedwe kukuchulukirachulukira. Monga kampani yoyesera mkati mwa makampani, Shandong Hongyue Environmental Engineering Co., Ltd. (yomwe tsopano ikutchedwa "Hongyue Environmental") posachedwapa idagwiritsa ntchito zaka zambiri zautumiki ndi maphunziro enieni kuti ifalitse mfundo zitatu zazikulu zokhudzana ndi kusankha ndi kukhazikitsa ma geotextiles. Akatswiri akuwona kuti cholinga cha polojekitiyi ndi kuthandiza omwe akukhudzidwa ndi polojekitiyi kupewa mavuto ofanana, potero kuchotsa—pa gwero—ngozi zachitetezo ndi kutayika kwachuma komwe kumachitika chifukwa cha kusankha zinthu mosayenera.
Vuto #1: Kuchepetsa Ndalama Mosazindikira ndi Kunyalanyaza Kufananiza Zinthu Zofunikira
Pankhani ya zomangamanga zoyendera, mapulojekiti ena—pofuna kusunga ndalama—amakonda kusankha ma geotextiles otsika mtengo; izi zimapangitsa kuti pakhale chiopsezo chachikulu pa ubwino wa polojekiti yonse. Pa kafukufuku wa m'munda, gulu laukadaulo la Hongyue Environmental linapeza kuti mapulojekiti ena amisewu yayikulu adagwiritsa ntchito ma polypropylene geotextiles olemera osakwana 100 g/m² pomanga maziko. Zipangizo zotere nthawi zambiri zimakhala ndi mphamvu yokoka yosakwana 8 kN/m; chifukwa chake, zimakhala zosavuta kubooledwa ndi miyala yophwanyika panthawi yoponderezedwa ndi makina olemera, kapena ngakhale kung'ambika chifukwa cha maziko ang'onoang'ono pambuyo poti msewu watsegulidwa kuti magalimoto azitha kuyenda—zomwe zimapangitsa kuti pakhale ming'alu pamwamba pa msewu.
Nkhani imodzi yodziwika bwino inali yokhudza pulojekiti ya msewu waukulu ku Shandong Province komwe, chifukwa cha kugwiritsa ntchito ma geotextiles osakwanira, msewu unayamba kuchepa miyezi itatu yokha mutatsegulidwa. Pomaliza pake, ntchitoyi inafunika kukonzanso kokwera mtengo—kupitirira 200,000 RMB—zomwe zinasokoneza kwambiri ntchito zoyendera ndi zoyendera za m'deralo. Kuphatikiza apo, ngati ma geotextiles opangidwira misewu ya sitima sanalandire chithandizo choletsa kukalamba, mphamvu zawo zitha kuchepa ndi 30% ngati zitasiyidwa pamalo otentha kwa miyezi itatu kenako n’kunyowa ndi madzi amvula.
Poganizira izi, Hongyue Environmental ikupereka malangizo otsatirawa: kusankha zinthu zamapulojekiti aukadaulo kuyenera kutsatira mfundo ya "kufananiza zofunikira." Pazinthu zofunika kwambiri pakupanga zinthu—monga kulimbitsa misewu—ma geotextiles a polyester filament amphamvu kwambiri kapena ma geotextiles apamwamba kwambiri a ulusi ayenera kusankhidwa. Kuphatikiza apo, kuyesa mwamphamvu kwa zizindikiro zazikulu zogwirira ntchito—monga kusweka kwa mphamvu ndi kung'amba—kuyenera kuchitika motsatira miyezo ya dziko (monga, GB/T 17638-2017); mtengo suyenera kukhala wokhawo womwe umatsimikizira kusankha zinthu.
Vuto Lachiwiri: Kusalowa Madzi Mokwanira ndi Kukana Kudzimbiritsa—Zoopsa Zobisika mu Mapulojekiti Osungira Madzi
Poyerekeza ndi kumanga misewu, mapulojekiti osamalira madzi amaika zofunikira kwambiri pankhani ya kusalowa madzi ndi kukana dzimbiri kwa zipangizo zomangira. Pamene ankapereka ntchito za nthambi za South-to-North Water Diversion Project, Hongyue Environmental Protection inapeza kuti ma geotextile opangidwa ndi opanga ambiri ang'onoang'ono anali ndi zolakwika zazikulu—monga kusatseka bwino malo olumikizirana ndi m'lifupi mwake zosakwana 10 cm—zomwe zinawapangitsa kukhala osavuta kutayikira. Chodabwitsa kwambiri n'chakuti, m'mapulojekiti okonzanso nthaka ya saline-alkali, ma polypropylene geotextile wamba—omwe alibe kukana kwa ma acid ndi alkali—nthawi zina ankasankhidwa molakwika. Izi zinapangitsa kuti zipangizozo zikalamba ndi kuwola mkati mwa miyezi isanu ndi umodzi yokha, zomwe zinapangitsa kuti ntchito yawo yoletsa kutuluka kwa madzi isagwire bwino ntchito.
"Kukana kofooka kwa madzi ndi dzimbiri kumabweretsa zoopsa zobisika m'makoma." Hongyue Environmental Protection ikugogomezera kuti pa ntchito zauinjiniya wa hydraulic—monga madamu ndi kukonzanso njira za mitsinje—ndikofunikira kusankha ma geotextiles ophatikizika kapena ma geomembrane a HDPE omwe ali ndi kukana kwabwino kwa mankhwala komanso kukana kubowoka. Zogulitsa zawo zimagwiritsa ntchito njira zomatira kutentha kapena zomatira kuti zitsimikizire kuti pali mgwirizano wolimba, wosagwirizana pakati pa geotextile ndi nembanemba yosalowa madzi, motero zimapirira kuwonongeka m'malo ovuta. Kuphatikiza apo, gulu lililonse la zinthu limayesedwa mwamphamvu kuti zitsimikizire kudalirika kwathunthu.
Lingaliro Lolakwika #3: Kusaganizira Molakwika za Kulowa kwa Mpweya—Zomera Zikuvutika Kupulumuka Pamalo Obiriwira
Pa ntchito zokonzanso migodi ndi kubzala mitengo yotsetsereka, kugwirizana kwa zinthu zomwe zimagwiritsidwa ntchito m'chilengedwe n'kofunika kwambiri. Magulu ambiri omanga amalakwitsa posintha "ma geomembrane osalowa madzi" m'malo mwa "ma geotextile olowa madzi." Izi zimaletsa chinyezi m'nthaka kuti isatuluke, zomwe zimapangitsa kuti mizu ya zomera ivutike ndi kusowa kwa mpweya ndikufota, zomwe zimapangitsa kuti pakhale kupulumuka kochepa kwambiri. Mwachitsanzo, ntchito yakale yokonzanso migodi, inawona kuti kupulumuka kwa mbewu za udzu kunatsika kufika pansi pa 30% chifukwa cha cholakwika ichi; pamapeto pake vutoli linathetsedwa pokhapokha mutasintha kugwiritsa ntchito ma polyester geotextile olowa mpweya.
Pofuna kuthana ndi vutoli, Hongyue Environmental Protection ikunena kuti pakugwiritsa ntchito malo otsetsereka obiriwira, malo opangidwa ndi singano osalukidwa ayenera kuperekedwa patsogolo, omwe amapereka madzi abwino kwambiri komanso ma porosity ambiri. Zinthuzi sizimangothandiza kutulutsa madzi komanso zimagwira ntchito ngati fyuluta yobwerera m'mbuyo komanso zimaletsanso kukokoloka kwa nthaka, motero zimapangitsa kuti zomera zikule bwino. Zikagwiritsidwa ntchito limodzi ndi kusintha kwa nthaka, kuchuluka kwa zomera zomwe zimapulumuka kumatha kukwera kufika pa 85%, zomwe zimapangitsa kuti zivomerezedwe bwino panthawi yomaliza ya polojekiti yokonzanso zachilengedwe.
Kuwongolera Ubwino ndi Utumiki Wathunthu: Kukhazikitsa Benchmark Yatsopano ya Makampani
Pofuna kutsimikizira ubwino wa malonda, Hongyue Environmental Protection yakhazikitsa njira yowunikira magawo atatu yomwe ikukhudza njira yonse: kuyambira zipangizo zopangira mpaka kupanga, ndipo potsiriza mpaka chinthu chomalizidwa. Kampaniyo imagwiritsa ntchito tchipisi ta polyester tapamwamba kwambiri ngati zinthu zopangira ndipo imakhazikitsa malo owunikira bwino kwambiri pazigawo zofunika kwambiri—monga kuboola singano ndi lamination—kuti zitsimikizire kuti zinthuzo ndi zolondola. Kuphatikiza apo, kampaniyo imapatsa mabungwe ena odalirika kuti achite mayeso odziyimira pawokha, motero kuonetsetsa kuti mpukutu uliwonse wa geotextile wotuluka pamalopo ukugwirizana ndi miyezo ya dziko lonse.
Kupatula kupereka zinthu zabwino kwambiri, Hongyue Environmental imapereka phukusi lathunthu lautumiki limodzi lokhala ndi upangiri waukadaulo, kapangidwe ka mayankho, chitsogozo cha zomangamanga, ndi kukonza pambuyo pogulitsa. Kaya ikugwiritsidwa ntchito pa ntchito zazikulu za zomangamanga zapakhomo kapena kugwiritsidwa ntchito panthawi yomwe kampaniyo ikukula kupita kumisika yapadziko lonse, njira iyi yogwirira ntchito kuyambira pachiyambi mpaka kumapeto yatchuka kwambiri ndi kudziwika ndi makasitomala. Patsogolo, Hongyue Environmental ipitilizabe kusunga nzeru zake zazikulu—“Zokhazikika mu Ubwino, Zoyendetsedwa ndi Utumiki”—popeza imagwira ntchito yofunika kwambiri poteteza ndikuthandizira chitukuko cha zomangamanga ku China.
