Indlela yokwakha ye-TRD yazisa uphuhliso olutsha kumazantsi eTshayina, yaze yasetyenziswa kwiprojekthi yokuhlanganisa isikhululo sikaloliwe esinesantya esiphezulu saseShantou.

Kwiminyaka yakutshanje, indlela yokwakha ye-TRD iphuhliswe ngokukhawuleza e-China. Ekupheleni kowama-2021, inani lilonke leeprojekthi ze-TRD elizweni liya kudlula kuma-500, kwaye umthamo wokwakha we-TRD uwonke uya kufikelela phantse kwi-6 yezigidi ze-cubic metres. Xa kuthelekiswa nendlela yokwakha yendabuko, indlela yokwakha ye-TRD ineenzuzo ezininzi: ubunzulu obukhulu bokwakha, ukuguquguquka okubanzi kwi-stratum, umgangatho omhle wodonga, ukuchaneka okuphezulu okuthe nkqo, ukugcina izinto zokwakha, kunye nokhuseleko lwezixhobo eziphezulu. Isetyenziswe ngokubanzi kwisiseko esahlukileyo samakhethini okumisa amanzi, Ukuqiniswa kodonga lwe-groove eludongeni oludibanisa umhlaba, udonga lokuxuba umhlaba we-samente, i-landfill kunye nezinye iindawo zokuzihlukanisa ukungcola kunye nokugcinwa kwamanzi kwiindonga ezichasene ne-seepage kunye nezinye iindawo.

IPhondo laseGuangdong liphondo eliphuhlisiwe eliselunxwemeni kwilizwe lam. Ubuchwephesha bokwakha imfumba ye-SMW ye-axis emithathu sele ikhulile ukusukela oko yathi yaziswa eGuangdong yiShanghai Guangda Foundation Engineering Co., Ltd. kwiminyaka eli-10 eyadlulayo. Nangona kunjalo, indlela yokwakha ye-TRD isekwisiqalo sayo. Indlela yokwakha ye-TRD isetyenziswe kulwakhiwo oludibeneyo lwe-hub yesikhululo sikaloliwe se-Shantou esinesantya esiphezulu kwiPhondo lase-Guangdong, kunye nomthamo wokwakha omalunga ne-30,000 cubic metres, ephawula ukuphumelela kophuhliso lobuchwepheshe bokwakha i-TRD kumazantsi eChina.

Iprojekthi yokuhlanganiswa kwesikhululo sikaloliwe esinesantya esiphezulu saseShantou inotyalo-mali olupheleleyo lwe-3.418 yeebhiliyoni zeeyuan. Uhlaziyo kunye nemixholo yolwakhiwo ibandakanya iprojekthi yogcino lwezothutho lukaloliwe, iprojekthi yendlela yokuhambisa inkqubo yokuhambisa, kunye nesikwere esempuma esinendawo ye-150,000 yeemitha zesikwere. Ngenxa yenani elikhulu lamaqela okwakha e-TRD, oomatshini bokwakha ababini be-TRD-60D be-SEMW babemiselwe umsebenzi wokwakha. Ngokuzenzekelayo, inkampani ethatha inxaxheba kolu lwakhiwo lwe-TRD yi-Shanghai Guangda Foundation, kwaye enye yezixhobo yimveliso yokuqala ye-TRD eyaphuhliswa yi-SEMW, eyathengwa yi-Shanghai Guangda Foundation kwiminyaka eyi-10 eyadlulayo, kwaye inomthamo wokwakha we-61m ubunzulu. Emva kweminyaka elishumi ye-ups and downs, izixhobo ze-No. 1 TRD-60D zisencinci, amandla ayo asenamandla kakhulu, kwaye umgangatho wayo uthembekile kakhulu. Yenze igalelo elikhulu kuphuhliso lwenani elikhulu lamashishini eShanghai. Emva kweminyaka elishumi yophuhliso, iimveliso ze-SEMW ze-TRD ngoku zenze uthotho lwe-TRD-C50, TRD60D/E, TRD70D/E, TRD80E iimveliso, zihlala zihlaziya irekhodi lobunzulu bokwakha kunye nokusebenza kakuhle kolwakhiwo, kwaye itekhnoloji yemveliso ikude phambili. ishishini.

Le projekthi (East Plaza Area C) ibekwe kwimpuma kwisikhululo sikaloliwe ekhoyo e Shantou City, kufuphi nesakhiwo esicwangcisiweyo Shantou high-speed kwisikhululo sesikhululo sikaloliwe kwicala elingasentshona, ucwangciso Shaoshan Road kwicala elingasempuma, isikhululo sokucwangcisa North Road. ngecala langasentla, ukuceba ngecala lasezantsi. Indlela iZhannan Road, iprojekthi yayo yendawo engaphantsi komhlaba ikakhulu inemigangatho emithathu engaphantsi komhlaba, indawo yokupaka yolawulo lwesixeko kunye nendawo yokupaka iibhasi kwicala elingasentshona zisekwe ngokuyinxenye ngomaleko omnye ongaphantsi komhlaba, kwaye icandelo lezohambo lukaloliwe ligcinelwe embindini. Yomba umngxuma kunye.

Emva kokuba ukwakhiwa kweprojekthi kugqityiwe, indawo yokwakhiwa kweqonga leShantou iya kuba malunga ne-100,000 yeemitha zesikwele, eya kwenza inkqubo yezothutho yaseShantou "iphuculwe ngokupheleleyo" kwaye ibe yindawo yokuthutha ebanzi kunye "nokutshintshwa kwe-zero, ukuhlanganiswa kwesikhululo-sixeko, kunye nokuhamba kakuhle" eShantou. Ukuphuhliswa kweShantou kuye kwadlala indima yokuqhubela phambili, kwaye ukubaluleka kwayo kweqhinga kubaluleke kakhulu.

Indawo engqongileyo yomgodi wesiseko weprojekthi inzima. Ukuze kuncitshiswe impembelelo yokumbiwa komngxuma wesiseko kunye nemvula kwindawo ejikelezileyo, udonga olulinganayo lwesamente-yomhlaba oluxutywayo lusekwe ngaphandle kwesiseko somngxuma oxhasa iimfumba kwindawo yeC1 ukumisa amanzi. Indlela yemfumba + udonga lokuxuba lwesamente olulinganayo, indlela yokwakha ye-TRD, udonga olunzulu lwe-samente-yomhlaba oluxutywayo luyi-800mm ubukhulu kunye ne-39m ubunzulu, kwaye iprojekthi icwangciselwe ukugqitywa kwiintsuku ezingama-60.

Iiparamitha ezithile zezi zilandelayo: (1) Ubukhulu yi-800mm, umphakamo wodonga oluphezulu yi--3.3m, kwaye umphakamo ophantsi wodonga yi-42.3m; (2) I-PO 42.5 ibakala eliqhelekileyo lesamente yasePortland isetyenziselwa ukunyanga ukuxuba ulwelo, umlinganiselo wamanzi-samente yi-1.2, kunye nomxholo wesamente awukho ngaphantsi kwe-25 ~ 30%; (3) I-bentonite esekelwe kwi-sodium isetyenziselwa ukuxuba ulwelo lokumba, kwaye i-5 ~ 10% i-bentonite yongezwa kwi-cube nganye yomhlaba ophazamisekileyo; (4) Ukutenxa kokuma kodonga kungaphantsi kwe-1/250, ukutenxa kwendawo yodonga akukho ngaphezu kwe-20mm, ukutenxa kodonga lobunzulu abukho ngaphezu kwe-50mm, kwaye ukutenxa kobukhulu bodonga hayi ngaphezulu kwe-20mm.

Isicwangciso somgangatho kunye necandelo elinqamlezileyo lesiseko sokubiyelwa komngxuma simi ngolu hlobo lulandelayo:

Udonga lwe-TRD kule projekthi kufuneka ludlule kwiileya ezininzi zesanti, kwaye ubunzulu bodonga bufikelela kwi-39m, okunzima ukuyakha. Amanyathelo ekujoliswe kuwo ngala alandelayo:
1. Ngenxa yokuba udonga luyi-39m ubunzulu kwaye lufuna ukudlula kwiileya ezininzi zesanti, iimfuno zezixhobo zokwakha ze-TRD ziphezulu kakhulu. Phambi kokwakhiwa yonke imihla, umkhandi kufuneka ajonge izixhobo zeTRD. Itsheyini iyajongwa, kwaye umqolo weemela ezigugileyo kunye netyathanga zitshintshwa kwangethuba ukuze kuqinisekiswe ukukwazi ukusika izixhobo. 2. Xa usika, kuyimfuneko ukuthobela ingqalelo ukuba ibhokisi yokusika kunye nekhonkco ishukunyiswa ngokungaqhelekanga. Ukuba isantya sokusika siyancipha, okanye asikwazi ukuqhubela phambili, ukwakhiwa kufuneka kunqunyanyiswe kwaye kujongwe ngexesha.

Isixhobo sokwakha se-TRD samkela isalathiso sewotshi, okokuqala ukusuka emantla ukuya emazantsi ukusuka embindini wecala lempuma, emva koko ukusuka empuma ukuya entshona ukusuka kwikona esezantsi-mpuma, emva koko ukusuka emazantsi ukuya emantla ukusuka kwikona esezantsi-ntshona, ukusuka entshona ukuya empuma ukusuka kumantla-ntshona. ikona, kwaye ekugqibeleni ukusuka kumntla-mpuma kwikona Ukwakhiwa ukusuka emantla ukuya emazantsi, umzobo wokwakha ngolu hlobo lulandelayo:

ULian Po mdala, usengatya? Le ndlela yokwakha yaseShanggong Machinery TRD-60D igxotha amathandabuzo wonke ngedatha yokwakha. Ubunzulu buyi-39m, ubukhulu bodonga buyi-0.8m, ukusika iimitha ezi-2 kwiyure eli-1, ukuhoxiswa kweemitha ezi-4 kwiyure eli-1, kwaye i-shotcrete iimitha ezi-3 kwiyure eli-1. Inokwenziwa lula yonke imihla. Udonga lungaphezu kwe-15m, into ebizwa ngokuba "ludala kwaye lunamandla".
Kwelinye icala, omnye umatshini wokwakha weShanggong Machinery TRD-60D oveliswe ngoMatshi ka-2020 udityanisiwe kwaye uza kujoyina ulwakhiwo kungekudala. "Izizukulwana ezibini" zabadala nabancinci ziyavumelana kwaye ziya kupenda umfanekiso womgangatho kunye nelifa.

Ngokunyuka ngokuthe ngcembe kwiimeko zokusetyenziswa kweteknoloji yokwakha ye-TRD eMzantsi China, ukugqwesa kokwakhiwa kwe-TRD kuya kuqinisekiswa ngokuthe ngcembe. Siqinisekile ukuba iteknoloji yokwakha ye-TRD iya kufana neteknoloji ye-SMW kwiminyaka elishumi edlulileyo, kwaye iya kufezekisa uphuhliso olukhulu eMzantsi China.
