Njira yomanga ya TRD idayambitsa chitukuko chatsopano kum'mwera kwa China, ndipo idagwiritsidwa ntchito ku projekiti yophatikizira masitima apamtunda a Shantou

M'zaka zaposachedwa, njira yomanga ya TRD yakula kwambiri ku China. Pofika kumapeto kwa chaka cha 2021, chiwerengero chonse cha ntchito za TRD mdziko muno chidzapitirira 500, ndipo kuchuluka kwa TRD yomanga kudzafika pafupifupi ma kiyubiki mita 6 miliyoni. Poyerekeza ndi njira yomangira yachikhalidwe, njira yomangira ya TRD ili ndi zabwino zambiri: kuya kwakukulu komanga, kusinthasintha kwakukulu kwa stratum, mtundu wabwino wa khoma, kulondola kwambiri, kupulumutsa zida zomangira, ndi chitetezo chazida zapamwamba. Zakhala zikugwiritsidwa ntchito kwambiri muzitsulo zosiyanasiyana zazitsulo zazitsulo zoyimitsa madzi, Kulimbitsa khoma lolumikiza khoma la khoma, khoma losakanikirana ndi simenti yachitsulo, kutayirako ndi zina zodzipatula zowonongeka komanso kuteteza madzi otsutsa-seepage makoma ndi minda ina.

Chigawo cha Guangdong ndi chigawo chotukuka cha m'mphepete mwa nyanja m'dziko langa. Ukadaulo wachikhalidwe wa SMW wophatikizika ndi milu itatu wakhala wokhwima kwambiri kuyambira pomwe unayambitsidwa ku Guangdong ndi Shanghai Guangda Foundation Engineering Co., Ltd. zaka 10 zapitazo. Komabe, njira yomanga ya TRD ikadali yoyambira. Njira yomanga ya TRD idagwiritsidwa ntchito pakumanga kophatikizika kwa njanji yothamanga kwambiri ya Shantou m'chigawo cha Guangdong, ndikumanga pafupifupi ma kiyubiki mita 30,000, zomwe zikuwonetsa kupititsa patsogolo luso la zomangamanga la TRD kum'mwera kwa China.

Ntchito yophatikizira masitima apamtunda wa Shantou ili ndi ndalama zokwana yuan biliyoni 3.418. Zokonzanso ndi zomangamanga zikuphatikiza pulojekiti yosungira njanji, pulojekiti yogawa ma rampu, ndi malo akum'mawa omwe ali ndi malo okwana masikweya mita 150,000. Chifukwa cha kuchuluka kwa maphwando omanga a TRD, makina awiri omanga a TRD-60D a SEMW adayikidwa kuti agwire ntchito yomanga. Zodabwitsa ndizakuti, kampani nawo ntchito yomanga TRD ndi Shanghai Guangda Foundation, ndi chimodzi mwa zida ndi woyamba TRD mankhwala opangidwa ndi SEMW, amene anagulidwa ndi Shanghai Guangda Foundation zaka 10 zapitazo, ndipo ali ndi mphamvu yomanga 61m kuya. Pambuyo pa zaka khumi za kukwera ndi kutsika, zida za No. Zathandizira kwambiri pakukula kwa mabizinesi ambiri ku Shanghai. Pambuyo pazaka khumi zachitukuko, zinthu za SEMW za TRD tsopano zapanga mndandanda wa TRD-C50, TRD60D/E, TRD70D/E, TRD80E, zotsitsimula nthawi zonse mbiri yakuya kwa TRD yomanga ndi yomangamanga, ndipo ukadaulo wazinthu uli patsogolo kwambiri. makampani.

Ntchitoyi (East Plaza Area C) ili kum'mawa kwa siteshoni ya njanji yomwe ilipo ku Shantou City, moyandikana ndi nyumba yomanga njanji yothamanga kwambiri ya Shantou kumadzulo, ikukonzekera msewu wa Shaoshan kum'mawa, malo okonzekera North Road. mbali ya kumpoto, ndi kupanga mbali ya kumwera. Zhannan Road, projekiti yake yapansi panthaka imakhala ndi zipinda zitatu zapansi pansi, malo oimikapo magalimoto oyang'anira mzinda ndi malo oimika mabasi kumadzulo amakhazikitsidwa pang'ono ndi gawo limodzi lapansi panthaka, ndipo gawo la njanji limasungidwa pakati. Kumbani dzenje pamodzi.

Ntchito yomangayo ikamalizidwa, malo omanga nsanja ya Shantou adzakhala pafupifupi 100,000 masikweya mita, zomwe zipangitsa kuti mayendedwe a Shantou "apitirire bwino" ndikukhala malo oyendera mayendedwe ndi "zero transfer, station-city integration, ndi magalimoto osalala" ku Shantou. Kukula kwa Shantou kwatenganso gawo loyendetsa, ndipo kufunikira kwake ndikofunikira kwambiri.

Malo ozungulira a dzenje la maziko a polojekitiyi ndizovuta. Pofuna kuchepetsa zotsatira za kukumba dzenje la maziko ndi mvula pamalo ozungulira, khoma losakanikirana la simenti-dothi losakanikirana limayikidwa kunja kwa dzenje lothandizira milu m'dera la C1 kuti asiye madzi. Njira ya mulu + wofanana-wolemera simenti kusakaniza khoma, njira yomanga TRD, khoma lakuya la simenti-dothi losakanikirana ndi 800mm wandiweyani ndi 39m kuya, ndipo ntchitoyi ikukonzekera kumalizidwa m'masiku 60.

Magawo enieni ndi awa: (1) Kuchuluka kwake ndi 800mm, kukwera pamwamba pa khoma ndi -3.3m, ndipo pansi pa khoma ndi -42.3m; (2) PO 42.5 kalasi wamba Portland simenti ntchito kuchiritsa madzi kusakaniza, chiŵerengero madzi simenti ndi 1.2, ndi zili simenti si Ochepera 25 ~ 30%; (3) bentonite yochokera ku sodium imagwiritsidwa ntchito posakaniza madzi okumba, ndipo 5 ~ 10% bentonite imawonjezeredwa pa cube iliyonse ya nthaka yovunda; (4) Kupatuka kwa verticality ya khoma ndikochepera 1/250, kupatuka kwa khoma sikuposa 20mm, kupatuka kwa kuya kwa khoma sikupitilira 50mm, ndipo kupatuka kwa makulidwe a khoma ndi. osapitirira 20 mm.

Dongosolo la pansi ndi gawo lozungulira la dzenje la maziko ndi izi:

Khoma la TRD mu polojekitiyi liyenera kudutsa mchenga wambiri, ndipo kuya kwa khoma kumafika 39m, zomwe zimakhala zovuta kupanga. Njira zomwe akuyembekezeredwa ndi izi:
1. Chifukwa khomalo ndi lakuya kwa 39m ndipo liyenera kudutsa mchenga wambiri, zofunikira pa zipangizo zomangira za TRD ndizokwera kwambiri. Asanamangidwe tsiku lililonse, makaniko amayenera kuyang'ana zida za TRD. Unyolo umayang'aniridwa, ndipo mzere wa mpeni wong'ambika ndi unyolo umasinthidwa munthawi yake kuti zitsimikizire luso lodula la zida. 2. Podula, m'pofunika kumvetsera ngati bokosi lodula ndi unyolo zimagwedezeka mosadziwika bwino. Ngati liwiro lodula likucheperachepera, kapena silingapitirire patsogolo, ntchito yomangayi iyenera kuyimitsidwa ndikuchitidwa munthawi yake.

Zida zomangira za TRD zimatengera njira yowongoka, choyamba kuchokera kumpoto kupita kumwera kuchokera pakati pa mbali yakum'mawa, kenako kuchokera kummawa kupita kumadzulo kuchokera kukona yakumwera chakum'mawa, kenako kuchokera kumwera kupita kumpoto kuchokera kukona yakumwera chakumadzulo, kenako kuchokera kumadzulo kupita kummawa kuchokera kumpoto chakumadzulo. ngodya, ndipo potsiriza kuchokera kumpoto chakum'maŵa ngodya Kumanga kuchokera kumpoto mpaka kum'mwera, chithunzi cha zomangamanga chili motere:

Lian Po wakalamba, angadyebe? Njira yomanga ya Shanggong Machinery TRD-60D imachotsa kukayikira kwa aliyense ndi deta yomanga. Kuya kwake ndi 39m, makulidwe a khoma ndi 0.8m, kudula ndi 2 metres mu ola limodzi, kubweza ndi 4 metres mu ola limodzi, ndipo shotcrete ndi 3 metres mu ola limodzi. Zitha kuchitika mosavuta tsiku lililonse. Khomali ndi loposa 15m, lomwe limatchedwa "wakale ndi wamphamvu".
Kumbali inayi, makina ena omanga a Shanggong Machinery TRD-60D opangidwa mu Marichi 2020 asonkhanitsidwa ndipo alowa nawo ntchito yomanga posachedwa. "Mibadwo iwiri" ya achikulire ndi achichepere ikufanana wina ndi mzake ndipo idzajambula chithunzi cha khalidwe ndi cholowa.

Ndi kuwonjezeka kwapang'onopang'ono kwa milandu yogwiritsira ntchito teknoloji yomanga ya TRD ku South China, kupambana kwa zomangamanga za TRD kudzatsimikiziridwa pang'onopang'ono. Tili otsimikiza kuti teknoloji yomanga TRD idzakhala yofanana ndi teknoloji ya SMW zaka khumi zapitazo, ndipo idzapindula kwambiri ku South China.
