Ukwakhiwa kwensimbi yensimbi ye-Pile Cofferdam kukhiqizwe ngamanzi noma emanzini aseduze, okuhlose ukudala indawo eyomile nephephile yokwakha. Ukwakhiwa okungajwayelekile noma ukwehluleka ukubonakalisa ngokunembile umthelela wemvelo efana nekhwalithi yenhlabathi, ukugeleza kwamanzi, ingcindezi yokujula kwamanzi, njll. Ngokwezingozi zokuphepha.
Inqubo eyinhloko yokuphathwa kokuphepha kwe-Steel Sheet Pile Cofferdam yokwakha:
I. Inqubo yokwakha
1. Ukulungiselela ukwakhiwa
○ ukwelashwa kwesayithi
Ipulatifomu yokwakha egcwalisa idinga ukuhlanganiswa ungqimba ngesendlalelo (ubukhulu obunconyiwe yi-≤300cm) ukuqinisekisa ukuthi umthamo wokuthwala uhlangabezana nezidingo zokusebenza kwemishini.
Umthambeka we-drainage ditch kufanele abe ≥1%, futhi ithangi le-sedimentation kufanele isethwe ukuvikela i-silt blockage.
Ukulungiswa kwezinto ezibonakalayo
Ukukhetha kwe-Sheet Sheet Pile: Khetha uhlobo lwe-Pile ngokuya ngombiko we-Geological (njengohlobo lwe-Larsen IV lomhlabathi othambile nohlobo lwe-U Ungqimba lwe-gravel).
Bheka ubuqotho bokhiye: Faka ibhotela noma i-sealant kusengaphambili ukuvikela ukuvuza.
2. Ukulinganiswa nokwakheka
Sebenzisa isiteshi esiphelele sokuma okuqondile, setha ama-pils okulawula njalo nge-10m, bese uhlola i-axis design kanye nokuphambuka okuphakeme (iphutha elivumelekile ≤5cm).
3. Umhlahlandlela Wokufakwa Kwefreyimu
Ukuhlukaniswa kwezikhala phakathi kwemigwaqo yensimbi enomugqa ophindwe kabili kungu-1 ~ 2cm kukhulu kunobubanzi bezinqwaba zensimbi yensimbi ukuze uqinisekise ukuthi ukuphambuka kwe-vertiality kungaphansi kwe-1%.
Imigqa Yezihlahlandlela idinga ukulungiswa ngokushiswa kwensimbi noma ukufukula ukugwema ukuthuthwa ngesikhathi sokudlidliza.
4. I-Steel Sheet Pile Insication
○ Ukulandelana kokushayela kwenqwaba: Ukuqala kusuka kunqwaba yegumbi, vala igebe ngasohlangothini olude kuya oluphakathi, noma usebenzise ukwakhiwa kweqembu "isikrini"
Ukulawulwa Kwezobuchwepheshe:
Ukuphambuka kwe-verticality yenqwaba yokuqala kungu-≤0.5%, futhi umzimba we-pile olandelayo ulungiswa "ukushayela okubekiwe".
○ Izinga lokushayela kwenqwaba:
Ukwelashwa kokuvalwa: Uma igebe elisele lingafakwa ngezinqwaba ezijwayelekile, sebenzisa izinqwaba ezibunjiwe ezikhethekile (njengezinqwaba ze-wedge) noma i-weld ukuvala.
I-5. Ukumba umgodi we-Foundation Pit
Ukumbiwa okuyisisekelo (ungqimba ngamunye
Uhlelo lokudonsa amanzi: Ukuhlukaniswa kwezikhala phakathi kwemithombo yokuqoqa amanzi kungama-20 ~ 30m, kanye namaphampu angenakuhwalala (izinga lokugeleza ≥10mm / h) asetshenziselwa ukupompa okuqhubekayo.
6. Ukubuyiselwa emuva kanye nokukhishwa kwenqwaba
I-Baclefill idinga ukuhlanganiswa ngokulinganayo ezingxenyeni (i-compaction degree ≥ 90%) ukugwema ukuguquguquka kwe-cofferdam ngenxa yokucindezela okungathandeki.
Ukulandelana kokukhishwa kwenqwaba: Susa kusuka maphakathi kuya ezinhlangothini zombili ngezikhathi ezithile, bese ufaka amanzi noma isihlabathi ngasikhathi sinye ukunciphisa ukuphazamiseka kwenhlabathi.
II. Ukuphathwa Kwezokuphepha
1. Ukulawulwa kwengozi
○ Ukuqunjelwa kwe-anti-isikhathi: Ukuqashwa kwangempela kwesikhathi se-cofferdam deformation (kumisa ukwakhiwa nokuqinisa lapho izinga lokuthambekela likhulu kune-2%).
○ Ukuvuza okuvuthayo: Ngemuva kokuphola, hang a mesh ngaphakathi ukuze ufafaze i-grout noma ubeke i-geroofteproof heaterproof.
○ Ukushona: Setha ama-Guardrails (Height ≥ 1.2m) neLifebuoys / izintambo endaweni yokusebenza.
2. Ukuphendula ezimweni zokusebenza ezikhethekile
Ithonya elinamandla
○ Isexwayiso esindayo semvula: amboze umgodi weSisekelo kusengaphambili futhi uqale imishini yokudonsa isipele (njengamaphampu wamandla aphezulu).
3. Ukuphathwa Kwezemvelo
Ukwelashwa kwe-Mud Sedimentation Treatment: Setha ithangi elisezingeni eliphakeme le-sedimentation bese ulikhipha ngemuva kokuhlangana namazinga.
Ukulawulwa komsindo
Ⅲ. Inkomba ebalulekile yezobuchwepheshe inkomba
IV. Izinkinga ezijwayelekile nokwelashwa
1. Ukuphambuka kwenqwaba
Imbangela: Izinto ezinzima engxenyeni yenhlabathi noma i-oda elingalungile lokuphamba.
Ukwelashwa: Sebenzisa "izinqwaba zokulungiswa" ukubuyisa umjovo noma ukugcwaliswa kwenqwaba yendawo.
2. Ukukhiya ukuvuza
Ukwelashwa: Gcwalisa izikhwama zobumba ngaphandle bese ujova i-polyurethane Foaming ejenti ngaphakathi ukuze uphawu.
3. Isisekelo Phit Uplift
Ukuvimbela: ukusheshisa ukwakhiwa kwepuleti elingaphansi futhi kunciphise isikhathi sokuvezwa.
V. Isifingqo
Ukwakhiwa kwensimbi yensimbi ye-pile cofferdams kufanele kugxile ku- "ezinzile (isakhiwo ezinzile), okumsulwa (ukubekwa uphawu phakathi kwamaphayiphu), futhi ngokushesha (ukuvalwa okusheshayo (ukuvalwa okusheshayo)", futhi kuguqule amandla inqubo ngokuhambisana nezimo zezwe. Ezindaweni ezijulile zamanzi noma i-strata eyinkimbinkimbi, i- "ukwesekwa kuqala bese igaya" noma "i-cofferdam ehlanganisiwe" (inqwaba yensimbi ye-anti-seepage + ingathathwa. Ukwakhiwa kwalo kuqukethe inhlanganisela yamandla namandla. Ibhalansi ephelele phakathi kwendoda nemvelo ingaqinisekisa inqubekela phambili ebushelelezi yokwakha futhi inciphise ukulimala kanye nokuchitha izinsiza zemvelo.
