VII. Ukushayela inqwaba yeshidi lensimbi.
Ukwakhiwa kwenqwaba yensimbi ye-Larsen kuhlobene nokumiswa kwamanzi nokuphepha ngesikhathi sokwakhiwa. Kungenye yezinqubo ezibaluleke kakhulu kule phrojekthi. Ngesikhathi sokwakha, lezi zidingo ezilandelayo zokwakha kufanele ziqashelwe:
(1) Izinqwaba zamashidi ensimbi ye-Larsen zishayelwa abashayeli benqwaba yezinqwaba. Ngaphambi kokushayela, kufanele ujwayelane nezimo zamapayipi angaphansi komhlaba nezakhiwo futhi ubeke ngokucophelela umugqa ophakathi nendawo wenqwaba yokusekela.
(2) Ngaphambi kokushayela, hlola inqwaba yeshidi lensimbi ngalinye futhi ukhiphe izinqwaba zeshidi lensimbi ezigqwalile noma ezikhubazekile kakhulu ekhiyeni yokuxhuma. Zingasetshenziswa kuphela ngemva kokuba sezilungisiwe futhi sezifanelekile. Lezo ezingakafanelekile ngemuva kokulungiswa azivunyelwe.
(3) Ngaphambi kokushayela, amafutha angasetshenziswa ekukhiyeni inqwaba yeshidi lensimbi ukuze kube lula ukushayela nokususwa kwenqwaba yeshidi lensimbi.
(4) Phakathi nenqubo yokushayela inqwaba yeshidi lensimbi, ukuthambekela kwenqwaba ngayinye kufanele kulinganiswe futhi kuqashwe ukuthi kungabi ngaphezu kuka-2%. Uma ukuchezuka kukukhulu kakhulu ukuthi kungalungiswa ngendlela yokudonsa, kufanele kukhishwe futhi kuqhutshwe futhi.
(5) Qiniseka ukuthi izinqwaba zamashidi ensimbi azikho ngaphansi kwamamitha ama-2 ukujula ngemva kokumbiwa, futhi uqinisekise ukuthi zivalwa kahle; ikakhulukazi, amakhona amane okuhlola kahle kufanele asebenzise izinqwaba zeshidi lensimbi ekhoneni. Uma zingekho lezi zinqwaba zamashidi ensimbi, sebenzisa amathayi amadala noma amanikiniki ukuze ugcwalise izithungo nezinye izinyathelo ezisizayo ukuze uzivale kahle ukuvimbela ukuvuza nesihlabathi ekubangeleni ukubhidlika komhlabathi.
(6) Ukuze uvimbele ukucindezela kwenhlabathi ehlangothini ekucindezeleni inqwaba yeshidi lensimbi phansi ngemva kokumbiwa komsele, ngemva kokuqhutshwa kwezinqwaba zeshidi lensimbi, sebenzisa i-H200*200*11*19mm I-imishayo ukuxhuma izinqwaba zeshidi lensimbi ye-Larsen izinhlangothi zombili zomzila ovulekile zibe zizonke, cishe u-1.5m ngaphansi kwenqwaba, futhi uzishisele ngezinti zokushisela zikagesi. Bese, sebenzisa insimbi eyindilinga engenalutho (200*12mm) njalo kumamitha angu-5, futhi usebenzise amalunga akhethekile anyakazayo ukusekela izinqwaba zeshidi lensimbi nhlangothi zombili ngokulinganayo. Lapho usekela, amantongomane amajoyinti anyakazayo kufanele aqiniswe ukuze kuqinisekiswe ukuma kwezinqwaba zeshidi lensimbi ye-Larsen kanye nendawo yokusebenza yokumba umsele.
(7) Ngesikhathi sokumbiwa komsele wesisekelo, bheka izinguquko zezinqwaba zeshidi lensimbi nganoma yisiphi isikhathi. Uma kukhona ukugumbuqela okusobala noma ukuphakamisa, ngokushesha wengeze ukwesekwa okulinganayo ezingxenyeni eziguquliwe noma eziphakanyisiwe.
Ⅷ. Ukususwa kwezinqwaba zeshidi lensimbi
Ngemuva kokuthi umgodi wesisekelo usugcwalisiwe, izinqwaba zeshidi lensimbi kufanele zisuswe ukuze zisetshenziswe kabusha. Ngaphambi kokukhipha izinqwaba zeshidi lensimbi, ukulandelana kwezindlela zokususa inqwaba, isikhathi sokususa inqwaba kanye nokwelashwa kwemigodi yenhlabathi kufanele kufundwe ngokucophelela. Uma kungenjalo, ngenxa yokudlidliza kokukhishwa kwenqwaba kanye nenhlabathi eyeqile ethwalwa yizinqwaba, umhlabathi uzocwila futhi ugudluke, okuzolimaza isakhiwo esingaphansi komhlaba esakhiwe futhi kuthinte ukuphepha kwezakhiwo zokuqala eziseduze, izakhiwo noma amapayipi angaphansi komhlaba. Kubaluleke kakhulu ukuzama ukunciphisa inhlabathi ethwelwe yizinqwaba. Njengamanje, izinyathelo eziyinhloko ezisetshenziswayo umjovo wamanzi kanye nomjovo wesihlabathi.
(1) Indlela yokukhipha inqwaba
Le phrojekthi ingasebenzisa isando esidlidlizayo ukuze idonse izinqwaba: sebenzisa ukudlidliza okuphoqelelwe okukhiqizwa isando esinyakazayo ukuze uphazamise inhlabathi futhi ucekele phansi ukuhlangana kwenhlabathi ezungeze izinqwaba zeshidi lensimbi ukuze unqobe ukumelana nokukhipha inqwaba, futhi uthembele ekuphakamiseni okwengeziwe. phoqa ukubasusa.
(2) Izinyathelo zokuqapha lapho udonsa izinqwaba
a. Iphoyinti lokuqala nokulandelana kokukhipha inqwaba: Odongeni lomthelela wepuleti lensimbi elivaliwe, indawo yokuqala yokukhipha inqwaba kufanele ibe ngaphezu kuka-5 kude nezinqwaba zamakhona. Indawo yokuqala yokukhipha inqwaba inganqunywa ngokusho kwesimo lapho izinqwaba zicwiliswa, futhi indlela yokukhipha i-jump ingasetshenziswa uma kunesidingo. Ukuhleleka kokukhishwa kwenqwaba kungcono kakhulu ukuthi kuphambene nalokho ukushayela inqwaba.
b. Ukudlidliza nokudonsa: Lapho ukhipha inqwaba, ungasebenzisa isando esidlidlizayo kuqala ukudlidliza isiphetho sokukhiya senqwaba yeshidi ukuze unciphise ukunamathela kwenhlabathi, bese uyikhipha ngenkathi idlidliza. Ezinqwaba zamashidi okunzima ukuzikhipha, ungasebenzisa isando sikadizili kuqala ukudlidliza inqwaba phansi ngo-100~300mm, bese uyidlidliza ngokunye futhi uyikhiphe ngesando esidlidlizayo.
(3) Uma inqwaba yeshidi lensimbi ingakwazi ukukhishwa, izinyathelo ezilandelayo zingathathwa:
a. Sebenzisa isando esidlidlizayo ukuze usishaye futhi ukuze unqobe ukumelana okubangelwa ukunamathela emhlabathini kanye nokugqwala phakathi kokulunywa;
b. Khipha izinqwaba ngokulandelana okuphambene kwenqwaba yeshidi ngokulandelana kokushayela;
c. Umhlabathi oseceleni kwenqwaba yeshidi elithwala ukucindezela kwenhlabathi uminyene. Ukushayela enye inqwaba yeshidi ngokuhambisana eduze kwayo kungenza inqwaba yeshidi lokuqala iphume kahle;
d. Yenza ama-grooves ezinhlangothini zombili zenqwaba yeshidi bese ufaka i-bentonite slurry ukuze unciphise ukumelana lapho ukhipha inqwaba.
(4) Izinkinga ezijwayelekile nezindlela zokwelashwa ekwakhiweni kwenqwaba yeshidi lensimbi:
a. Tshekisa. Isizathu sale nkinga ukuthi ukumelana phakathi kwenqwaba eqhutshwayo kanye nelokhi yenqwaba eseduze kukhulu, kuyilapho ukumelana nokungena endaweni yokushayela inqwaba kuncane; izindlela zokwelapha yilezi: sebenzisa amathuluzi ukuhlola, ukulawula kanye nokulungisa noma nini phakathi nenqubo yokwakha; sebenzisa intambo yocingo ukudonsa umzimba wenqwaba lapho kutshekiswa, donsa futhi ushayele ngesikhathi esifanayo, futhi kancane kancane uyilungise; gcina ukuchezuka okufanele kwenqwaba yeshidi elishayelwayo.
b. I-Torsion. Isizathu sale nkinga: ingidi iwukuxhuma okunamaphiko; izindlela zokwelapha yilezi: vala ilokhi yangaphambili yenqwaba yeshidi ngekhadi lapho ushayela khona inqwaba; setha amabakaki e-pulley ezikhaleni ezinhlangothini zombili phakathi kwezinqwaba zeshidi lensimbi ukuze umise ukujikeleza kwenqwaba yeshidi ngesikhathi sokucwila; gcwalisa izinhlangothi ezimbili zebhande lokukhiya lezinqwaba zamashidi amabili ngamaphedi namadowels okhuni.
c. Ukuxhumana. Isizathu senkinga: inqwaba yeshidi lensimbi litshekile futhi ligobile, okwandisa ukumelana ne-slot; izindlela zokwelapha yilezi: lungisa ukutsheka kwenqwaba yeshidi ngesikhathi; lungisa okwesikhashana izinqwaba eziseduze ezishayelwe nge-angle iron welding.
9. Ukwelashwa kwemigodi yenhlabathi ezinqwabeni zeshidi lensimbi
Izimbobo zenqwaba ezisele ngemva kokukhipha izinqwaba kufanele zigcwaliswe emuva ngesikhathi. Indlela yokubuyisela emuva yamukela indlela yokugcwalisa, futhi izinto ezisetshenziswa endleleni yokugcwalisa ziyi-chips zamatshe noma isihlabathi esiphakathi nendawo.
Okungenhla incazelo eningiliziwe yezinyathelo zokwakhiwa kwezinqwaba zeshidi lensimbi ye-Larsen. Ungayidlulisela kubantu abadinga usizo abaseduze nawe, unake Imishini ye-Juxiang, futhi “ufunde okwengeziwe” nsuku zonke!
I-Yantai Juxiang Construction Machinery Co., Ltd. ingenye yezinkampani ezinkulu zokunamathisela i-excavator kanye nezinkampani ezikhiqizayo e-China. I-Juxiang Machinery inesipiliyoni seminyaka engu-16 ekukhiqizeni abashayeli benqwaba, onjiniyela bocwaningo nokuthuthukisa abangaphezu kuka-50, futhi ikhiqiza amasethi angaphezu kuka-2000 emishini yokushayela inqwaba ngonyaka. Igcina ukubambisana okuseduze nabakhiqizi bemishini yomugqa wokuqala basekhaya abafana no-Sany, i-XCMG, ne-Liugong. Imishini yokushayela inqwaba yeJuxiang Machinery yakhiwe kahle, ithuthuke kakhulu kwezobuchwepheshe, futhi isidayiselwe amazwe angu-18 emhlabeni wonke, ithola ukunconywa ngazwilinye. I-Juxiang inekhono elivelele lokuhlinzeka amakhasimende ngemishini yobunjiniyela ehlelekile nephelele nezisombululo, futhi ingumhlinzeki wesevisi wesixazululo semishini yobunjiniyela onokwethenjelwa.
Siyakwamukela ukubonisana nokusebenzisana nathi uma unezidingo.
