I-CASSING ROTATOR EBODWA ISEMINA YE-PILE Ibanjwe NGEMPUMELELO E-ZHUHAI

Kusukela ngoMeyi 13 kuya ku-14, isemina yokuzungeza okugcwele kanye nenqwaba yama-rotator enesithukuthezi, exhaswe ngokuhlanganyela yigatsha lezobunjiniyela benhlabathi kanye negatsha lobunjiniyela be-geotechnical lenhlangano yaseShayina yobunjiniyela bomphakathi kanye nenhlangano ye-Wuhan geotechnical engineering, futhi ihlelwe yi-Wuhan Xindi Geotechnical Engineering Technology Co., Ltd. kanye ne-SEMW yabanjelwa e-Hyatt Place Zhuhai Jinshi.

UGong Xiugang, imenenja jikelele ye-SEMW, iphini likasihlalo wekomiti elikhethekile lezobunjiniyela benhlabathi kanye negatsha lobunjiniyela be-geotechnical lenhlangano yaseShayina yobunjiniyela bomphakathi, u-Xiang Yan, uprofesa osezingeni eliphakeme unjiniyela we-Hubei Academy of Construction Sciences, ilungu elimile lekomidi elikhethekile lenhlabathi. Mechanics and geotechnical engineering branch of Chinese Society of civil engineering, kanye nesekela sihlalo we Wuhan geotechnical engineering society, USolwazi Hu Chunlin, unobhala jikelele kanye nesekela likamongameli we Wuhan geotechnical engineering Society, Solwazi Zhu Yanpeng we Lanzhou University of technology, abaningi ochwepheshe Wuhan geotechnical umphakathi wobunjiniyela kanye nabantu abangama-76 abavela eWuhan, Shanghai, Zhuhai, Shenzhen, Beijing, Changsha, Jiangsu, Zhengzhou naseGuangzhou babekhona emhlanganweni.

Indawo yenkomfa

Okuqukethwe kulo mhlangano kuhlanganisa ubuchwepheshe bokwakhiwa kwe-casing rotator, izinto zokusebenza kanye nomkhuba wobunjiniyela wenqwaba enesithukuthezi esakhiweni kuyashintshaniswa kakhulu.

Cishe ngo-8 ekuseni ngomhla ka-14, izithunywa zavakashela okokuqala iphrojekthi yokwakha i-Anxin yemvelo yase-Zhuhai hengqinhui, ukusetshenziswa kobuchwepheshe bokuzungeza i-casing kunjiniyela ojulile wesisekelo senqwaba. Indawo yephrojekthi itholakala echwebeni laseHengqin, edolobheni laseZhuhai. Indawo imbiwe kwaze kwaba sezingeni. Ukujula komgodi wesisekelo kungu-18m. Izinqwaba ezibhorekile ezingaphezu kuka-40 ezinobubanzi obungu-1.5m kanye nobude obuphelele obungama-65m (ngezansi komgodi) zakhiwe emgodini ojulile wesisekelo. I-geology yobunjiniyela besayithi iyinkimbinkimbi. Ingaphezulu lakhiwe ngodaka lolwandle olujulile, ungqimba lwesihlabathi esisheshayo kanye negwadle ukusuka phezulu kuye phansi. Isikhathi esiphelele senqwaba yokuhlola yokuqala singaphansi kwamahora angama-36.

Ubunzima ekwakhiweni kwephrojekthi:

(1) Izimo zejoloji eziyinkimbinkimbi:izimo zamatshe nenhlabathi yendawo yephrojekthi ziyinkimbinkimbi kakhulu, amamitha angu-20 ngaphansi komhlaba udaka lolwandle, i-20 M-60 ngaphansi komhlaba iyisihlabathi esisheshayo, futhi ukuphela kwenqwaba kungena ku-granite enesimo sezulu esilinganiselwe ngamamitha angu-2;

(2) Indawo yokwakha ewumngcingo:indawo yokwakha isemgodini ojulile wesisekelo, eduze kwezakhiwo, isakhiwo esisekelayo kanye ne-crisscross yesisekelo senqwaba ekhona, futhi isikhala sincane, okuholela ekutheni i-crane ingakwazi ukuthatha inhlabathi ngokujwayelekile, ngakho-ke izinyathelo ezikhethekile kufanele zithathwe ukuze kuqedwe. ukuthatha umhlabathi nokwakhiwa kwemigodi;

(3) Amanzi avalelwe kakhulu emzimbeni wenqwaba:izinga lamanzi lamanzi avaliwe liphakeme ngamamitha angu-7 ngaphezu kokuphansi komgodi, okulula ukubangela izingozi zamapayipi kungqimba lwesihlabathi ngaphakathi kwepayipi, futhi ukwakhiwa kunzima kakhulu.

Inkampani yokwakha yamukela umshini wokuqala ozishayelayo oyi-rotary oyi-dtr2106hz e-China ukwenza umsebenzi wokwakha. Okokusebenza kufakwe idivayisi yokukhasa, enezici zoguquko oluguquguqukayo, i-torque enkulu nokusebenza kahle okuphezulu kokwakhiwa. Ingakwazi ukuhlangabezana nemibandela yokwakha kanye nezidingo zendawo yokuphakama okuphansi (njenge-culvert nomhubhe) futhi iqinisekise ukuqhubeka kahle kwephrojekthi.

Ukubhekwa kwendawo yokwakha

Cishe ngo-10 ekuseni, kwaba nomhlangano wombiko wokushintshana ngezemfundo egumbini lenkomfa lehhotela, usingathwe u-Xiang Yan, isekela likamongameli.

Iphini lika-Xiang Yan liphethe umhlangano

U-Cheng Jielin, umphathi jikelele we-Wuhan Xindi Geotechnical Engineering Technology Co., Ltd., wenze umbiko wokuxhumana wale phrojekthi: ubuchwepheshe bokwakhiwa kwenqwaba enkulu kanye nenqwaba ende enomshini wokumba i-casing rotator emgodini wesisekelo ojulile wesistimu yokusekela inqwaba, kanye nokusetshenziswa kwezindlela eziningi zokwakha ze-casing rotator ekulungiseni umgodi wesisekelo kanye nephrojekthi yokuqinisa yokukhiya umkhumbi.

Ukuvikelwa kwezindonga zensimbi kusetshenziswa ekwakhiweni kwenqwaba ye-cast-in-place ene-rotary egcwele kanye ne-casing rotator, enezici zekhwalithi enhle yokwakha inqwaba, akukho ukungcoliswa kodaka, ukuvikelwa kwemvelo okuluhlaza kanye nokunciphisa i-coefficient yokugcwalisa ukhonkolo. Ingakwazi ukuxazulula ngokuphumelelayo izinkinga zokuwa kwemigodi, i-necking kanye ne-coefficient yokugcwalisa ephezulu ekwakhiweni kwenqwaba ye-cast-in-place ngendlela evamile yokwakha emadolobheni Isetshenziswa kabanzi ku-petrochemical nakwezinye izinkambu zokwakha.

Ekwakhiweni kwemiklamo emikhulu yengqalasizinda enyakatho naseningizimu yeChina, i-SEMW isiphenduke ithuluzi lokwakha elaziwayo endaweni eyinkimbinkimbi yokuma komhlaba. Eminyakeni edlule, i-SEMW ibilokhu ibheka ukusungulwa kanye ne-R & D njengokuncintisana okuyinhloko kwenkampani, ilandela eduze umngcele womhlaba wonke wokukhiqiza imishini nobuchwepheshe bokwakha, iletha inani lomkhiqizo "lenkonzo yobungcweti, ukudalwa kwenani" embonini nakubasebenzisi ngaso sonke isikhathi. , nokwakha ngokuhlanganyela ikhaya elihle.
