中文Ukwakhiwa kwemfumba eyenziwe kwangaphambili "ithwala isiphatho",
Ingxolo ephantsi, ukungcangcazela okuncinci, ukonga amandla kunye nokunciphisa ukukhutshwa,
Isiseko semfumba yasezidolophini "isixhobo sokukhusela indalo".
kutshanje
Kwindawo yokwakha yeprojekthi yesigaba sokuqala sokuxhasa iShanghai Huahong Hongli FAB2,
Iiseti ezimbini zoomatshini be-static drilling kunye ne-rooting nganye bagcina indawo yabo kwaye benze ukwakhiwa ngaxeshanye.
Ujongene nedabi elinzima lokulwa nexesha kunye nexesha,
"Thatha ingcambu" ezantsi ngobunzulu, uzinze ngakumbi kwaye uchaneke ngakumbi ukulwa,
Beka isiseko esiluqilima seprojekthi yeHuahong Grace.
Isiseko semfumba sale projekthi samkela indlela yokomba emileyo yeemfumba ezineengcambu. Kusetyenziswe i-1,298 yeemfumba ezineengcambu, ezimalunga neemitha ezingama-42,000, kwaye ubude bemfumba bungama-29-36m. Khetha uhlobo lwemfumba: PHC 500(100) AB C80 + PHDC 550-400(95) AB-500/400 C80, i-drilling diameter: 650mm, ububanzi bokwandisa ezantsi: 975mm, ukuphakama kokwandiswa okuphantsi: 2000mm.
Isiza sikufuphi neendlela nezakhiwo ezikhoyo kwaye sinemibhobho. Iimeko zokusingqongileyo zintsonkothile kwaye zinovakalelo kwi-deformation kunye ne-vibration enokuthi yenzeke ngexesha lokwakhiwa kwesiseko. Iimfuno zokucuthwa komhlaba kulwakhiwo lwesiseko semfumba ziphezulu kakhulu. , Indlela yokugqiba iprojekthi kwiintsuku ezingama-40 phantsi kweemeko ezinzima zokusebenza zokwenziwa kodaka kwisiza sokwakhiwa kwakhona kuye kwaba ngomnye weengxaki kulwakhiwo lwesiseko semfumba sale projekthi.
Njengesixhobo sokwakha isiseko semfumba eluhlaza kunye nokusingqongileyo ngokuzimeleyo ngokuzimeleyoSEMW, I-SDP220H yokugrumba i-static kunye nomatshini wokuqhafaza iye yaba yinto yokuqala yokukhetha iqela leprojekthi ngenxa yokusebenza kwayo kakuhle kwemveliso. Le mveliso ayinayo i-torque enkulu kuphela, ubunzulu obukhulu bokugaya, ukuthembeka okulungileyo kunye nokusebenza kakuhle kokwakhiwa, kodwa ineempawu zokunyakaza okuncinci, ingxolo ephantsi, ukonga amandla kunye nokunciphisa ukukhutshwa ngexesha lokwakha.
Isantya, ubunzulu, kunye nokuchaneka yeyona ndlela ilungileyo yokutolika kwe-SDP220H yokugrumba i-static kunye nomatshini wokucothula. Iziqwenga ezibini zezixhobo kwisiza zinokufumba malunga ne-300m yeemfumba ngosuku olunye ngomatshini omnye, kwaye ulwakhiwo olusebenzayo lumalunga neemfumba ezili-10-12, ukuqinisekisa inkqubela ezinzileyo nesebenzayo yokwakha.
Kwiimveliso ezigqwesileyo, imarike ayilokothi ithandabuze ukuzincoma. Impendulo esuka kumqhubi wendawo: "Njengomsebenzi wegqala osebenze umatshini iminyaka emininzi,SEMWI-SDP220H ye-SDP220H yokugrumba kunye nomatshini wokuhluma unetorque enkulu, amandla awomeleleyo, ukugrumba okuphezulu kakhulu kunye nokusebenza kakuhle kolwakhiwo olusezantsi, kwaye wonke umatshini usebenza ngokuthembekileyo nangokuzinzileyo. Lukhetho olufanelekileyo lweprojekthi." Isiqinisekiso esisebenzayo sokwakha. "
Njengomboneleli okhokelayo kwishishini lezisombululo ezipheleleyo zolwakhiwo oluphantsi komhlaba, kwiminyaka yakutshanje, i-SEMW iye yaqhubeleka ukwenza impumelelo ngokuqhubekayo malunga nokukhuthaza ulwakhiwo olungundoqo lwetekhnoloji, uphando lwemveliso entsha kunye nophuhliso, kunye nokwandisa uyilo lwemarike.
Kwixesha elizayo, i-SEMW iya kuqhubeka igxile kwimbono yabathengi kunye nembono yemarike, izama ukudala iingenelo ezingundoqo ezikhuphisanayo kunye neemveliso, ngokuyilayo ukuhlangabezana neemfuno zokwenene zabathengi kunye nexabiso lemali, kwaye ikhokele ushishino lolwakhiwo oluphantsi komhlaba phambili.
Intshayelelo yendlela yokwemba i-static
Indlela yokugrumba emileyo kunye nengcambu isebenzisa isixhobo sokugrumba esimileyo kunye nemfumba yokwemba ukugrumba imingxunya, ixube kuyo yonke inkqubo kwaye yandise umzantsi, kwaye ekugqibeleni ifakele umzimba wemfumba owenziweyo, okuthetha ukuba iimfumba zekhonkrithi ze-bamboo (PHDC) ezigxininiswe ngaphambili. -i-tensioned pre-tensioned bamboo piles, njl. Iimpawu ezahlukeneyo kunye neemodeli zemibhobho yekhonkrithi egxininisiweyo (i-PHC) kunye ne-composite ye-prestressed prestressed prestressed concrete pipe piles (PRHC) zidityaniswe ngeendlela ezahlukeneyo ukuhlangabezana neemfuno zokuyila, kwaye zakhiwe ngokugrumba, ukukhulisa, ukugrumba, ukufakwa kunye nezinye iinkqubo. indlela yokwakha isiseko semfumba.
Iimpawu zendlela yokwakha:
●Akukho kucudisa umhlaba, akukho kungcangcazela, ingxolo ephantsi;
●Umgangatho wemfumba ulungile kwaye umphezulu wemfumba uyalawuleka ngokupheleleyo;
●Uxinzelelo oluthe nkqo oluqine kakhulu, ukutsalwa kunye namandla okumelana nomthwalo othe tye;
●Ukukhutshwa kodaka okuncinci;
●Unezibonelelo ezilungileyo zentlalo kunye nexabiso lokunyusa.
Ubungakanani besicelo:

●Umhlaba odibeneyo, intlenga, umhlaba oyisanti, umhlaba ozalise umhlaba, umhlaba otyumkileyo (igrabile) wamatye, kunye nokwakheka kwamatye aneemeko zejoloji ezintsonkothileyo, i-interlayers ezininzi, imozulu engalinganiyo, kunye notshintsho olukhulu lokuthamba nobulukhuni, ubunzulu obukhulu bokungena komhlaba: 90m;
Xa isiza sokwakha sisecaleni kwezakhiwo (izakhiwo) okanye imibhobho engaphantsi komhlaba kunye nezinye izibonelelo zobunjineli, ukusebenzisa ezinye iindidi zeengqumba kuya kubangela iziphumo ezibi;
●Ukuphakama komphezulu wengqumba ekupheleni komgangatho wokuthwala utshintsha kakhulu kwaye ubude bemfumba kunzima ukucacisa ngokuchanekileyo, indawo yokwakha ayinayo imiqathango yokugalela ikhonkrithi kwisiza okanye umgangatho wokugalela ikhonkrithi kwisiza asiyiyo. kulula ukuqinisekiswa;
●Iiprojekthi ezinezithintelo ekukhutshweni komthamo omkhulu wodaka;
●Xa uyilo lufuna imfumba enye ukuba ibe nomthamo omkhulu wokuthwala, kwaye izibonakaliso zobugcisa kunye nezoqoqosho kunye neemeko zokwakha ziphezulu kunezinye iintlobo zeemfumba.
Intshayelelo kwi-SDP static yokomba kunye nomatshini wokucothula
Uluhlu lwe-SDP lokomba olungaguqukiyo kunye nendlela yokwemba iirigi sisizukulwana esitsha semveliso yokomba ezimeleyo ngokupheleleyo.SEMWkwaye zikulungele ukugrumba okumileyo kunye nolwakhiwo lwendlela yokuncothula, ukuthatha ithuba lokuxutywa okunzulu kokugrumba iinzuzo ze-R&D eziqokelelwe ngokuhamba kweminyaka.
Iimpawu zendlela yokwakha:
1. Yamkela itekhnoloji yokwandiswa kwe-hydraulic esezantsi esezantsi, i-diameter yokwandiswa esezantsi yi-1-1.6 amaxesha edayamitha yomngxuma, kunye nokuphakama komngxuma ongezantsi kuphindwe kathathu umngxuma wokubhoboza, kwaye usebenzise indlela esezantsi yokurekhoda idatha yekhompyuter ukujonga ulwakhiwo. inkqubo Iidatha ezahlukeneyo kwinkqubo zirekhodwa kwaye zihlalutywe ukwenza ii-curves zedatha ezihambelanayo.
2. Yamkela isoftware yolawulo lolwakhiwo olukrelekrele kwaye usebenzise isilawuli sesikrini sokuchukumisa esikrelekrele ukujonga inkqubo yokwakha ngexesha lokwenyani ukuqinisekisa umgangatho wokwakha. Yonke idatha yokwakha ibonakaliswe ngokucacileyo kwisiboniso kwaye igcinwe ngokuzenzekelayo, kwaye inokukhutshwa kwaye iprintwe.
3. Inkqubo yokusebenza ixhotyiswe ngeprogram yokuvala ngokuzenzekelayo i-380V xa amandla elahlekile, ukuqinisekisa ukuba idatha ayiyi kulahleka ngenxa yokuphahlazeka okanye ukuphuma kwamandla ngexesha lokusetyenziswa kwe-drilling rig.
4. Indlela yokuqalisa injini isebenzisa isiqalo esithambileyo. I-soft starter ngokwayo inemisebenzi eyahlukeneyo yokukhusela i-motor, efana ne-under-voltage, ukulahleka kwesigaba, ukulandelelana kwesigaba, ukulayisha ngaphezulu kunye nolunye ukhuselo.
5. I-teknoloji yokwandisa i-hydraulic bottom inomsebenzi othembekileyo kwaye isebenzisa i-high-quality hydraulic components ukuqinisekisa ukuba ukwandiswa kwe-hydraulic bottom isebenza ngokuqhelekileyo kubunzulu be-80m.
Izinto eziluncedo kwi-static yokomba iimfumba ezineengcambu
Ukugrumba okumileyo okuneengqumba ezineengcambu zisebenzisa izixhobo zokugrumba ezinengxolo ephantsi (i-static drilling) kunye neendlela zokungcwaba ukugqiba iimfumba ezisele zenziwe (ukutyalwa kweemfumba). Yinkosi yeteknoloji yesiseko semfumba yanamhlanje. Emva kweminyaka yokukhuthazwa kunye nokusetyenziswa, iingenelo zayo ezibalulekileyo "ngaphezulu, ngokukhawuleza, ngcono kwaye zinoqoqosho ngakumbi" ezifana nokukhuselwa kokusingqongileyo okuluhlaza, ukonga amandla kunye nokunciphisa ukukhutshwa kwezinto kuye kwaqatshelwa kakhulu kuwo onke amacandelo oluntu.
