I-CASING ROTATOR IYAQHWA NESEMINA YE-PIILE IBE NGEMPUMELELO E-ZHUHAI

Ukusukela nge-13 kaMeyi ukuya kwi-14, isemina yokujikeleza ngokupheleleyo kunye ne-casing rotator imfumba ekruqukileyo, ixhaswe ngokudibeneyo ngobuchwephesha bomhlaba kunye nesebe lobunjineli be-geotechnical loluntu lwaseTshayina lobunjineli boluntu kunye ne-Wuhan geotechnical engineering engineering, kwaye iququzelelwe ngu-Wuhan Xindi Geotechnical Engineering Technology Co., Ltd. kunye ne-SEMW yayibanjelwe eHyatt Place Zhuhai Jinshi.

UGong Xiugang, umphathi jikelele we-SEMW, usekela-sihlalo wekomiti ekhethekileyo yobuchwephesha bomhlaba kunye nesebe lobunjineli be-geotechnical yoluntu lwaseTshayina lobunjineli boluntu, uXiang Yan, unjingalwazi wenqanaba eliphezulu leNjineli yeHubei Academy yeSayensi yokwakha, ilungu elimileyo lekomiti ekhethekileyo yomhlaba. oomatshini kunye nesebe lobunjineli be-geotechnical loMbutho waseTshayina wobunjineli boluntu, kunye nosekela sihlalo we-Wuhan geotechnical engineering, uNjingalwazi Hu Chunlin, unobhala jikelele kunye nosekela mongameli we-Wuhan geotechnical engineering society, uNjingalwazi uZhu Yanpeng weYunivesithi yaseLanzhou yetekhnoloji, iingcali ezininzi zeWuhan geotechnical. Uluntu lobunjineli kunye nabantu abangama-76 abavela eWuhan, eShanghai, eZhuhai, eShenzhen, eBeijing, eChangsha, eJiangsu, eZhengzhou naseGuangzhou bebezimase intlanganiso.

Indawo yenkomfa

Imixholo yentlanganiso ibandakanya itekhnoloji yolwakhiwo lwe-casing rotator, izixhobo kunye nobunjineli bokwenza imfumba ekruqukileyo ephoswayo iyatshintshwa ngokubanzi.

Malunga nentsimbi yesi-8 kusasa ngomhla we-14, abathunywa batyelela okokuqala iprojekthi yokwakha yaseZhuhai hengqinhui yendalo ye-Anxin, ukusetyenziswa kobuchwephesha be-casing rotator kubunjineli obunzulu besiseko semfumba yesiseko. Indawo yeprojekthi ikwizibuko laseHengqin, kwisiXeko saseZhuhai. Indawo igrunjwe kwisiseko. Ubunzulu bomgodi wesiseko yi-18m. Iimfumba ezingaphezu kwama-40 ezikruqukileyo ezinobubanzi obuyi-1.5m kunye nobude obuyi-65m bubonke (ngaphantsi komngxuma) zakhiwe kumngxuma onzulu wesiseko. Ubume bobunjineli bendawo buntsonkothile. Umphezulu wenziwa ludaka lolwandle olunzulu, umaleko wesanti ekhawulezayo kunye negranite ukusuka phezulu ukuya ezantsi. Ixesha elipheleleyo lemfumba yovavanyo lokuqala lingaphantsi kweeyure ezingama-36.

Ubunzima kulwakhiwo lweprojekthi:

(1) Iimeko zejoloji ezintsonkothileyo:iimeko zamatye kunye nomhlaba wesiza seprojekthi zinzima kakhulu, i-20 m ngaphantsi komhlaba ludaka lolwandle, i-20 M-60 ngaphantsi komhlaba yi-quicksand, kwaye isiphelo semfumba singena kwi-granite ephakathi kwe-2 m;

(2) Indawo yokwakha emxinwa:indawo yokwakha ikumngxuma onzulu wesiseko, omelene nezakhiwo, ulwakhiwo oluxhasayo kunye nengqumba ekhoyo yesiseko crisscross, kwaye indawo imxinwa, nto leyo ekhokelela ekubeni i-crane ingakwazi ukuthatha umhlaba ngokuqhelekileyo, ngoko kufuneka kuthathwe amanyathelo akhethekileyo ukuze kugqitywe. ukuthatyathwa komhlaba kunye nokwenza umngxuma;

(3) Amanzi avaleleke kakhulu kumzimba wemfumba:inqanaba lamanzi lamanzi avaliweyo li-7m phezulu kunomzantsi womgodi, okulula ukubangela iingozi zemibhobho kuluhlu lwesanti ngaphakathi kombhobho, kwaye ukwakhiwa kunzima kakhulu.

Inkampani yokwakha yamkela umatshini wokuqala we-dtr2106hz oziqhubayo we-rotary e-China ukwenza ulwakhiwo lweprojekthi. Isixhobo sixhotyiswe ngesixhobo sokukhasa, esineempawu zenguqu eguquguqukayo, i-torque enkulu kunye nokusebenza kakuhle kokwakhiwa. Inokuhlangabezana nemigaqo yolwakhiwo kunye neemfuno zemo engqongileyo yobude obuphantsi (efana nekholvethi kunye netonela) kwaye iqinisekise inkqubela phambili egudileyo yeprojekthi.

Ukuqwalaselwa kwendawo yokwakha

Malunga nentsimbi yeshumi kusasa, intlanganiso yengxelo yokutshintshiselana ngezifundo yabanjwa kwigumbi lenkomfa lehotele, eyayibanjwe nguXiang Yan, usekela mongameli.

Isekela lika-Xiang Yan lichophele intlanganiso

U-Cheng Jielin, umphathi jikelele we-Wuhan Xindi Geotechnical Engineering Technology Co., Ltd., wenze ingxelo yonxibelelwano yale projekthi: itekhnoloji yolwakhiwo lobukhulu obukhulu kunye nemfumba emide kakhulu enomatshini wokugrumba i-casing rotator kumngxuma onzulu wesiseko senkqubo yokuxhasa imfumba, kunye nokusetyenziswa kwendlela yolwakhiwo oluninzi lwe-casing rotator kwisiseko sokulungiswa komngxuma kunye neprojekthi yokuqinisa isitshixo senqanawa.

Ukukhuselwa kweendonga zensimbi kusetyenziswe ekwakhiweni kwe-cast-in-place imfumba kunye ne-rotary epheleleyo kunye ne-casing rotator, eneempawu zomgangatho omhle wokwenza imfumba, akukho ngcoliseko lodaka, ukukhuselwa kokusingqongileyo okuluhlaza kunye nokunciphisa i-coefficient yokuzalisa ikhonkrithi. Iyakwazi ukusombulula ngokufanelekileyo iingxaki zokuwa komngxuma, i-necking kunye ne-coefficient yokuzaliswa okuphezulu ekwakhiweni kwe-cast-in-place pile kunye nendlela eqhelekileyo yokwakha kwiidolophu Isetyenziswa ngokubanzi kwi-petrochemical kunye nezinye iindawo zokwakha.

Kulwakhiwo lweeprojekthi ezinkulu zeziseko ezingundoqo kumantla nakumazantsi eTshayina, i-SEMW iye yaba sisixhobo esaziwayo sokwakha kwindawo entsonkothileyo yokwakheka komhlaba. Ukutyhubela iminyaka, i-SEMW ibisoloko ithatha into entsha kunye ne-R & D njengokhuphiswano olungundoqo lwenkampani, ilandela ngokusondeleyo umda wehlabathi wokwenziwa kwezixhobo kunye nolwakhiwo lwetekhnoloji, ukuhambisa ixabiso lophawu “lwenkonzo yobuchwephesha, ukudalwa kwexabiso” kushishino nakubasebenzisi ngalo lonke ixesha. , kunye nokwakha ngokudibeneyo ikhaya elihle.
