Indlela yokwakha ye-TRD yethule intuthuko entsha eningizimu yeChina, futhi yasetshenziswa kuphrojekthi yokuhlanganisa ihabhu lesiteshi sesitimela saseShantou

Eminyakeni yamuva nje, indlela yokwakha ye-TRD ithuthuke ngokushesha eChina. Ekupheleni konyaka wezi-2021, ingqikithi yenani lemiklamo ye-TRD ezweni izokwedlula ama-500, kanti isamba sokwakhiwa kwe-TRD sizofinyelela cishe kuma-cubic metres ayizigidi eziyisi-6. Uma kuqhathaniswa nendlela yokwakha yendabuko, indlela yokwakha ye-TRD inezinzuzo eziningi: ukujula okukhulu kokwakha, ukuguquguquka okubanzi ku-stratum, ikhwalithi enhle yodonga, ukunemba okuphezulu okuqondile, ukonga izinto zokwakha, nokuphepha kwemishini ephezulu. Isetshenziswe kabanzi kumakhethini ahlukene wesisekelo somgodi wokumisa amanzi , Ukuqiniswa kodonga lwe-groove odongeni oluxhumanisa umhlabathi, udonga oluhlanganisiwe lwensimbi yensimbi yesimende, indawo yokulahla imfucumfucu kanye nokunye ukuhlukaniswa kokungcola kanye nezindonga zokuvikela amanzi zokunqanda ukubola nezinye izinkambu.

Isifundazwe saseGuangdong siyisifundazwe esisogwini esithuthukile ezweni lami. Ubuchwepheshe bendabuko bokwakha inqwaba ye-SMW ehlanganisa ama-eksisi amathathu sebukhulile impela kusukela bafakwa e-Guangdong yi-Shanghai Guangda Foundation Engineering Co., Ltd. eminyakeni eyi-10 edlule. Nokho, indlela yokwakha ye-TRD isaqala. Indlela yokwakha ye-TRD yasetshenziswa ekwakhiweni okudidiyelwe kwesikhungo sesiteshi sesitimela esinesivinini esikhulu sase-Shantou esiFundazweni sase-Guangdong, esinomthamo wokwakha ocishe ube ngama-cubic metres angu-30,000, okuphawula intuthuko yobuchwepheshe bokwakha be-TRD eningizimu yeChina.

Iphrojekthi yokuhlanganisa ihabhu lesiteshi sesitimela esinesivinini esiphezulu iShantou inotshalomali oluphelele lwezigidigidi ezi-3.418 zamayuan. Ukulungiswa nokwakhiwa kokuqukethwe kufaka phakathi iphrojekthi yokubhuka ezokuthutha ngojantshi, iphrojekthi yerempu yesistimu yokusabalalisa, kanye nesikwele esisempumalanga esinendawo engamamitha-skwele ayi-150,000. Ngenxa yobuningi bamaqembu okwakha e-TRD, imishini emibili yokwakha ye-TRD-60D ye-SEMW yamiswa emsebenzini wokwakha. Ngokuqondana nje, inkampani ebambe iqhaza kulokhu kwakhiwa kwe-TRD yi-Shanghai Guangda Foundation, futhi enye yemishini ingumkhiqizo wokuqala we-TRD owakhiwe yi-SEMW, owathengwa yi-Shanghai Guangda Foundation eminyakeni engu-10 edlule, futhi inamandla okwakha angama-61m ukujula. Ngemuva kweminyaka eyishumi ye-ups and downs, imishini ye-No. 1 TRD-60D isencane, amandla ayo asenamandla kakhulu, futhi izinga layo lithembekile kakhulu. Ibe negalelo elikhulu ekuthuthukisweni kwenani elikhulu lamabhizinisi e-Shanghai. Ngemuva kweminyaka eyishumi yokuthuthuka, imikhiqizo ye-SEMW's TRD manje isisungule uchungechunge lwemikhiqizo ye-TRD-C50, TRD60D/E, TRD70D/E, TRD80E, ehlala ivuselela irekhodi lokujula kokwakhiwa kwe-TRD nokusebenza kahle kokwakhiwa, futhi ubuchwepheshe bomkhiqizo buseza kakhulu imboni.

Lo msebenzi (i-East Plaza Area C) isempumalanga yesiteshi sikaloliwe esikhona eDolobheni laseShantou, eduze nesakhiwo sesiteshi sikaloliwe esinesivinini esiphezulu iShantou esisentshonalanga, sihlela umgwaqo uShaoshan ohlangothini olusempumalanga, isiteshi sokuhlela iNorth Road. ohlangothini olusenyakatho, futhi ukuhlela ohlangothini olungaseningizimu. I-Zhannan Road, iphrojekthi yawo yesikhala esingaphansi komhlaba ikakhulukazi inezitezi ezintathu ezingaphansi komhlaba, indawo yokupaka abaphathi bedolobha nendawo yokupaka amabhasi ohlangothini olusentshonalanga zimiswe ngokwengxenye ngongqimba olulodwa olungaphansi komhlaba, kanti ingxenye yezokuthutha ngojantshi ibekelwe phakathi. Bamba umgodi ndawonye.

Ngemuva kokuthi ukwakhiwa kwephrojekthi sekuqediwe, indawo yokwakha yesikhulumi seShantou izoba cishe ngamamitha-skwele ayi-100,000, okuzokwenza uhlelo lwezokuthutha lukaShantou "luthuthukiswe ngokuphelele" futhi lube ihabhu eliphelele lezokuthutha "elinokudluliselwa kwe-zero, ukuhlanganiswa kwesiteshi nedolobha, kanye nethrafikhi ebushelelezi" e-Shantou. Ukuthuthukiswa kweShantou nakho kube neqhaza lokushayela, futhi ukubaluleka kwayo kwamasu kubaluleke kakhulu.

Indawo ezungezile yomgodi wesisekelo wephrojekthi iyinkimbinkimbi. Ukuze kuncishiswe umthelela wokumbiwa komgodi wesisekelo kanye nemvula endaweni ezungezile, udonga lokuxutshwa kukasimende nomhlabathi olulingana nokuqina lubekwe ngaphandle komgodi wesisekelo osekela izinqwaba endaweni ye-C1 ukuze kumiswe amanzi. Indlela yenqwaba + yodonga lokuxuba usimende olulingana nokuqina, indlela yokwakha i-TRD, udonga olujulile lokuxuba usimende luyi-800mm nobukhulu obungama-39m, futhi iphrojekthi kuhlelwe ukuthi iqedwe ezinsukwini ezingama-60.

Amapharamitha athile ami kanje: (1) Ugqinsi luwu-800mm, ukuphakama okuphezulu kodonga kungu--3.3m, kanti ukuphakama okuphansi kodonga kungu-42.3m; (2) Isigaba se-PO 42.5 sikasimende esivamile sasePortland sisetshenziselwa ukuphulukisa ukuxutshwa koketshezi, isilinganiso samanzi nosimende singu-1.2, futhi okuqukethwe usimende akukho Ngaphansi kuka-25~30%; (3) I-bentonite esekelwe kwi-sodium isetshenziselwa ukuxuba uketshezi lokumba, futhi i-bentonite engu-5 ~ 10% yengezwe ku-cube ngayinye yomhlabathi okhungathekile; (4) Ukuchezuka kokuma kodonga kungaphansi kuka-1/250, ukuchezuka kwendawo yodonga akukho ngaphezu kwama-20mm, ukuchezuka kokujula kodonga akukho ngaphezu kwama-50mm, futhi ukuchezuka kobukhulu bodonga hhayi ngaphezu kuka-20 mm.

Ipulani yaphansi kanye nengxenye enqamulayo yendawo ebiyelwe yomgodi wesisekelo imi kanje:

Udonga lwe-TRD kule phrojekthi ludinga ukudlula izingqimba eziningi zesihlabathi, futhi ukujula kodonga kufinyelela ku-39m, okunzima ukukwakha. Izinyathelo ezihlosiwe zimi kanje:
1. Ngenxa yokuthi udonga lujule ngama-39m futhi ludinga ukudlula izingqimba eziningi zesihlabathi, izidingo zempahla yokwakha ye-TRD ziphakeme kakhulu. Ngaphambi kokwakhiwa nsuku zonke, umakhenikha udinga ukuhlola imishini ye-TRD. Iketango liyahlolwa, futhi umugqa wommese ogugile kanye neketango kuyashintshwa ngesikhathi ukuze kuqinisekiswe ikhono lokusika lempahla. 2. Lapho usika, kuyadingeka ukunaka ukuthi ibhokisi lokusika kanye neketanga liyanyakaziswa ngokungavamile. Uma ijubane lokusika lehliswa, noma ngisho lingenakuthuthukiswa, ukwakhiwa kudinga ukumiswa futhi kusetshenzwe ngesikhathi.

Imishini yokwakha ye-TRD isebenzisa indlela yewashi, okokuqala isuka enyakatho iye eningizimu isuka maphakathi nohlangothi olusempumalanga, bese isuka empumalanga iye entshonalanga ukusuka ekhoneni eliseningizimu-mpumalanga, bese isuka eningizimu iye enyakatho ukusuka ekhoneni eliseningizimu-ntshonalanga, bese isuka entshonalanga iye empumalanga ukusuka enyakatho-ntshonalanga. ekhoneni, futhi ekugcineni kusukela ekhoneni elisenyakatho-mpumalanga Ukwakhiwa kusuka enyakatho kuya eningizimu, umdwebo wokwakha umi kanje:

ULian Po usekhulile, usengadla? Le ndlela yokwakha ye-Shanggong Machinery TRD-60D isusa ukungabaza kwawo wonke umuntu ngedatha yokwakha. Ukujula kungama-39m, ukujiya kodonga kungu-0.8m, ukusika kungamamitha ama-2 ngehora eli-1, ukuhlehla kungamamitha ama-4 ngehora eli-1, kanti i-shotcrete ingamamitha ama-3 ngehora elingu-1. Kungenziwa kalula nsuku zonke. Udonga lungaphezu kuka-15m, okuyilokho okubizwa ngokuthi "omdala futhi unamandla".
Ngakolunye uhlangothi, omunye umshini wokwakha weShanggong Machinery TRD-60D okhiqizwe ngoMashi 2020 usuqoqiwe futhi uzojoyina ukwakhiwa maduze. "Izizukulwane ezimbili" zabadala nabancane ziyananela futhi zizopenda isithombe sekhwalithi nefa.

Ngokukhula kancane kancane kwamacala okusetshenziswa kobuchwepheshe bokwakha be-TRD eNingizimu ye-China, ukuphakama kokwakhiwa kwe-TRD kuzoqinisekiswa kancane kancane. Siyaqiniseka ukuthi ubuchwepheshe bokwakha be-TRD buzofana nobuchwepheshe be-SMW eminyakeni eyishumi edlule, futhi buzozuza intuthuko enkulu eNingizimu China.
