VII. Steel sheet imfumba ukuqhuba.
Ukwakhiwa kwemfumba yentsimbi ye-Larsen inxulumene nokumisa amanzi kunye nokhuseleko ngexesha lokwakha. Yenye yeenkqubo ezibaluleke kakhulu kule projekthi. Ngexesha lokwakha, ezi mfuno zokwakha zilandelayo kufuneka ziqatshelwe:
(1) Iimfumba zentsimbi yeLarsen ziqhutywa ngabaqhubi beemfumba ze crawler. Ngaphambi kokuba uqhube, kufuneka uqhelane neemeko zemibhobho engaphantsi komhlaba kunye nezakhiwo kwaye ubeke ngokucophelela umgca ochanekileyo ophakathi kweemfumba zokuxhasa.
(2) Ngaphambi kokuba uqhube, jonga nganye imfumba yentsimbi yentsimbi kwaye ususe iipali zentsimbi ezinomhlwa okanye ezikhubazeke kakhulu kwi-lock lock. Zingasetyenziswa kuphela emva kokuba zilungisiwe kwaye zifanelekile. Ezo zingekaqinisekiswa emva kokulungiswa azivumelekanga.
(3) Ngaphambi kokuba uqhube, igrisi ingasetyenziselwa ukukhiya intsimbi yentsimbi ukuze kube lula ukuqhuba kunye nokususwa kwentsimbi yentsimbi.
(4) Ngethuba lenkqubo yokuqhuba inqwaba yentsimbi, ukuthambeka kwemfumba nganye kufuneka kulinganiswe kwaye kubekwe iliso ukuba kungabi ngaphezu kwe-2%. Xa ukuphambuka kukhulu kakhulu ukuba kungalungiswa yindlela yokutsala, kufuneka ikhutshwe kwaye iqhutywe kwakhona.
(5) Qinisekisa ukuba iimfumba zeshiti lentsimbi azikho ngaphantsi kweemitha ezi-2 ubunzulu emva kokugrumba, kwaye uqinisekise ukuba zinokuvaleka kakuhle; ngokukodwa, iikona ezine zokuhlola kakuhle kufuneka zisebenzise iimfumba zentsimbi yekona. Ukuba akukho zimfumba zamaphepha entsimbi, sebenzisa amatayara amadala okanye amalaphu ukugcwalisa i-seams kunye namanye amanyathelo ancedisayo ukuze uvale kakuhle ukuthintela ukuvuza kunye nesanti ekubangeleni ukuwa komhlaba.
(6) Ukuze uthintele uxinzelelo lomhlaba osecaleni ekucudiseni i-sheet sheet yentsimbi emva kokwembiwa komsele, emva kokuba iipali zentsimbi ziqhutywe, sebenzisa i-H200 * 200 * 11 * 19mm i-I-beams ukudibanisa i-Larsen sheet sheet . macala omabini ejelo elivulekileyo libe lilonke, malunga ne-1.5m ngaphantsi komphezulu wemfumba, kwaye udibanise ngeentonga ze-welding zombane. Emva koko, sebenzisa intsimbi engqukuva engqukuva (200 * 12mm) rhoqo ngeemitha ezi-5, kwaye usebenzise amalungu akhethekileyo ashukunyiswayo ukuxhasa iimfumba zentsimbi kumacala omabini ngokulinganayo. Xa uxhasa, amandongomane eekhonkco ezihambayo kufuneka aqiniswe ukuze kuqinisekiswe ukuqina kweemfumba ze-Larsen sheet sheet kunye nomsele osebenzayo wokumba.
(7) Ngexesha lokumba umsele wesiseko, jonga utshintsho lweemfumba zentsimbi yentsimbi nangaliphi na ixesha. Ukuba kukho ukuguqulwa okucacileyo okanye ukuphakamisa, ngokukhawuleza yongeza inkxaso ye-symmetrical kwiindawo eziguqulweyo okanye eziphakanyisiweyo.
Ⅷ. Ukususwa kweemfumba zeshiti lentsimbi
Emva kokuba umngxuma wesiseko ubuyiselwe umva, iimfumba zeshiti lentsimbi kufuneka zisuswe ukuze zisetyenziswe kwakhona. Ngaphambi kokususa iimfumba zentsimbi, ukulandelelana kweendlela zokususa imfumba, ixesha lokususa imfumba kunye nokunyangwa komngxuma womhlaba kufuneka kufundwe ngokucophelela. Kungenjalo, ngenxa yokushukuma kokususwa kwemfumba kunye nomhlaba ogqithisileyo othwalwa ziimfumba, umhlaba uya kutshona kwaye ushukume, nto leyo eya konakalisa isakhiwo esingaphantsi komhlaba esakhiweyo kwaye sichaphazele ukhuseleko lwezakhiwo ezikufuphi zangaphambili, izakhiwo okanye imibhobho engaphantsi komhlaba. Kubaluleke kakhulu ukuzama ukunciphisa umhlaba othwalwa ziimfumba. Okwangoku, amanyathelo aphambili asetyenziswayo yinaliti yamanzi kunye nesitofu sesanti.
(1) Indlela yokukhupha imfumba
Le projekthi inokusebenzisa isando sokungcangcazela ukutsala iimfumba: sebenzisa ukungcangcazela okunyanzeliswayo okuveliswe sisando sokungcangcazela ukuphazamisa umhlaba nokutshabalalisa ukudityaniswa komhlaba ujikeleze iimfumba zeshiti lentsimbi ukoyisa ukuchasana nokutsalwa kwemfumba, kwaye uthembele ekunyuseni okongeziweyo. nyanzela ukuba basuse.
(2) Izilumkiso xa utsala iimfumba
a. Indawo yokuqala kunye nolandelelwano lokutsalwa kweemfumba: Kudonga oluvaliweyo lweplate yentsimbi, indawo yokuqala yokukhutshwa kwemfumba kufuneka ibe ngaphezu kwe-5 ukusuka kwiimfumba zekona. Indawo yokuqala yokutsalwa kwemfumba inokumiselwa ngokwemeko xa iimfumba zitshona, kwaye indlela yokutsiba yotsalo ingasetyenziswa xa kukho imfuneko. Ulandelelwano lokutsalwa kweemfumba lungcono ukuba luchasane nolo lokuqhuba imfumba.
b. Ukungcangcazela kunye nokutsala: Xa ukhupha imfumba, ungasebenzisa isando esingcangcazelayo kuqala ukungcangcazelisa isiphelo sokutshixa semfumba yeshiti ukunciphisa ukuncamathela komhlaba, kwaye emva koko uyitsale ngelixa ungcangcazela. Kwiimfumba zamashiti ekunzima ukuzikhupha, ungasebenzisa isando sedizili kuqala ukungcangcazelisa ingqumba ukuya kutsho kwi-100 ~ 300mm, emva koko uyingcangcazele uyikhuphe ngehamile engcangcazelayo.
(3) Ukuba imfumba yentsimbi yentsimbi ayinakutsalwa, la manyathelo alandelayo anokuthathwa:
a. Sebenzisa isando sokungcangcazela ukuze uyibethe kwakhona ukuze unqobe ukuchasana okubangelwa ukunamathela kunye nomhlaba kunye nomhlwa phakathi kokuluma;
b. Khupha iimfumba ngendlela echaseneyo yolandelelwano lokuqhuba lwemfumba yeshiti;
c. Umhlaba okwicala lengqumba yeshiti ethwele uxinzelelo lomhlaba uxinene. Ukuqhuba enye imfumba yeshiti ngokunxuseneyo kufutshane nayo kunokwenza ukuba imfumba yamaphepha oqobo itsale kakuhle;
d. Yenza i-grooves kumacala omabini e-sheet pile kwaye ufake i-bentonite slurry ukunciphisa ukuxhathisa xa ukhupha imfumba.
(4) Iingxaki eziqhelekileyo kunye neendlela zonyango ekwakhiweni kweemfumba zentsimbi:
a. Ukuthambeka. Isizathu sale ngxaki kukuba ukuxhathisa phakathi kwemfumba eqhutywa kunye ne-lock lock ekufutshane inkulu, ngelixa ukuchasana nokungena kwindlela yokuqhubela imfumba kuncinci; iindlela zonyango zezi: sebenzisa izixhobo zokujonga, ukulawula nokulungisa nanini na ngexesha lenkqubo yokwakha; sebenzisa intambo yocingo ukutsala umzimba wemfumba xa ukuthambeka kusenzeka, tsala kwaye uqhube ngaxeshanye, kwaye ngokuthe ngcembe ulungise; gcina ukutenxa okufanelekileyo kwimfumba yephepha lokuqala eliqhutywayo.
b. Torsion. Isizathu sale ngxaki: isitshixo ludibaniso olunehenjisi; iindlela zonyango zezi: tshixa isitshixo sangaphambili semfumba yeshiti kunye nekhadi kwicala lokuqhuba imfumba; setha izibiyeli ze-pulley kwizikhewu kumacala omabini phakathi kweemfumba zeshiti lentsimbi ukumisa ukujikeleza kwemfumba yephepha ngexesha lokutshona; Gcwalisa amacala amabini eqhina leemfumba zamaphepha amabini ngeepadi kunye needowels zomthi.
c. Co-uqhagamshelwano. Isizathu sengxaki: inqwaba yeshidi lensimbi iyancipha kwaye igobile, eyandisa ukuchasana kwe-slot; iindlela zonyango zezi: lungisa ukuthambeka kwemfumba yephepha ngexesha; lungisa okwethutyana iimfumba ezikufutshane eziye zaqhutywa nge-engile yentsimbi ye-welding.
9. Ukunyangwa kwemingxuma yomhlaba kwiimfumba zentsimbi
Imingxunya yemfumba eshiyekileyo emva kokukhupha iimfumba kufuneka izaliswe ngasemva. Indlela yokubuyisela i-backfill ithatha indlela yokuzalisa, kunye nezinto ezisetyenziswe kwindlela yokuzalisa i-chips zamatye okanye isanti ephakathi.
Oku ngasentla yinkcazo ecacileyo yamanyathelo okwakhiwa kwee-Larsen sheet sheet sheets. Ungayithumela kubantu abasweleyo abakungqongileyo, nikela ingqalelo kwiJuxiang Machinery, kwaye "ufunde ngakumbi" yonke imihla!
