Izinqwaba zamashidi ensimbiziyizakhiwo zensimbi ezinezinqubo ezihlanganayo. Ngokuhlanganisa izinqwaba ngazinye, zakha udonga oluqinile, oluqinile olubambayo. Asetshenziswa kakhulu kumaphrojekthi afana nama-cofferdam kanye nokusekelwa komgodi wesisekelo. Izinzuzo zabo eziyinhloko amandla aphezulu, kalula ukushayela emhlabathini oqinile, nezinhlobonhlobo zezitayela zokuxhuma, ezifana noLarsen noLackawanna.
Yiziphi izinhlobo zezinqwaba zeshidi lensimbi
Inqwaba Yeshidi Lensimbi Emise Okungu-Z:Izinqwaba zamashidi ensimbi anomumo ongu-Z ziyizingxenye zensimbi ezigoqeke ngokushisayo noma ezigotshwe ngokubanda ezinengxenye enqamulayo enomumo othi "Z", ehlanganisa iwebhu, ama-flange kanye nezingidi. Ngenxa yobubanzi be-flange kanye nesakhiwo sewebhu esiwugqinsi, zinokugoba okuhle kakhulu nokungagundi, futhi zingamelana kahle nenhlabathi esemaceleni nezingcindezi zamanzi. Izingidi zitholakala ekugcineni kwama-flanges, futhi ngemva kokuhlanganisa, zingakha isakhiwo sokugcina esingenamoya esiphezulu. Futhi baneyunithi enkulu yesisindo seyunithi modulus, izinto ezisebenzisekayo eziphansi, futhi zingasetshenziswa kabusha izikhathi ezi-3-5, ngomnotho ovelele. Ngesikhathi sokwakhiwa, izinqwaba zicwiliswa umshayeli wenqwaba okhethekile, futhi zingahlukaniswa ngokushesha ngaphandle kokushisela okwengeziwe, okuzenze zifanelekele izindawo ezincane. Asetshenziswa kakhulu ezimeni zobunjiniyela ezifana nokusekela umgodi ojulile wesisekelo sezakhiwo nemizila ehamba ngaphansi, ukuvalwa kwamanzi kwamadamu okonga amanzi, indawo ebiyelwe yamapayipi kamasipala, nokulawulwa kwezikhukhula kwesikhashana nokugcinwa kwamanzi.
Inqwaba Yeshidi Lensimbi Emise Okuka-U:Izinqwaba zamashidi ensimbi anomumo ongu-U ziyizingxenye zensimbi ezigoqeke ngokushisayo noma ezigotshwe ngokubanda ezinengxenye enqamulayo emise okuka-"U" kanye namajoyinti okukhiya alinganayo. Umnyombo uqukethe iwebhu, ama-flange amabili aseceleni kanye namajoyinti okukhiya ekugcineni. Isakhiwo esilinganayo siyenza ithwale amandla alinganiselayo, futhi inokubili ukumelana okuhle kokugoba kanye nokuzinza okuphelele. Amalunga okukhiya ahlanganiswe ngokuqinile, futhi ngemva kokuhlanganisa, angakha ngokushesha udonga olugcinayo oluqhubekayo nolwe-anti-seepage. Uma kuqhathaniswa nezinye izinhlobo zezinqwaba zamashidi ensimbi, inenqubo yokukhiqiza evuthiwe, izindleko eziphansi, futhi ingasetshenziswa kabusha. Ngesikhathi sokwakhiwa, izinqwaba zingacwiliswa yi-vibration noma umshayeli wenqwaba ye-static pressure. Ukusebenza kulula futhi kuyasebenza. Isetshenziswa kakhulu emiseleni yemigwaqo kamasipala, usekelo lwemigodi emincane yesisekelo, amadamu esikhashana wokudonsa amanzi, ukuvikelwa kosebe lomfula kanye nezindonga zesikhashana zendawo yokwakha. Ifaneleka ngokukhethekile izidingo zobunjiniyela ezinokujula okuphakathi nendawo nokuncane futhi izwela izindleko zokuvaleka.
Yiziphi izakhiwo zokufakwa kwepuleti lensimbi
Izici zezinqwaba zamashidi ensimbi zimboza izilinganiso eziyinhloko njengesigaba sezinto ezibonakalayo, izakhiwo zokukhanda kanye nokucaciswa kosayizi. Phakathi kwazo, Inqwaba Yeshidi Lensimbi Ye-Carbon iyisigaba sezinto eziyisisekelo, esihlanganisa amamaki ensimbi athile ahlukahlukene, njenge-Q345b Steel Sheet Pile kanye ne-Sy295 Steel Sheet Pile ngaphansi kwendinganiso yaseShayina. Eyangaphambili iyinsimbi eqinile enengxubevange ephansi enamandla okukhiqiza angu-≥345MPa kanye nokuqina komthelela ofanelekayo ezingeni lokushisa legumbi, nezici zemishini ezibanzi ezilinganiselwe. Lesi sakamuva singamandla avamileinqwaba ye-carbon steel sheetngamandla esivuno ≥295MPa kanye nepulasitiki enhle kakhulu kanye nokushisela. Kukhona futhi Inqwaba Yeshidi Lensimbi elisezingeni le-S355jo, elinamandla esivuno ≥355MPa kanye nokuqina komthelela -20℃ okuhlangabezana nezinga, nokusebenza okuhle kakhulu kwezinga lokushisa eliphansi. Ngokwezicaciso zosayizi, i-600*360 Steel Sheet Piles imele imodeli yesigaba esikhulu enobubanzi be-cross-section engu-600mm nobude obungu-360mm, enokumelana nokucindezela okuqinile kwezinhlangothi. Inqwaba Yeshidi Lensimbi engu-12m isho ubude obuyi-12m. Ukucaciswa okumaphakathi nokude kunganciphisa ukuhlanganisa futhi kuthuthukise i-anti-seepage. Lezi zinqwaba zeshidi lensimbi ezinezakhiwo ezihlukene zingashintshwa ukuze zivumelane nezimo ezihlukahlukene kusukela kumaphrojekthi wesikhashana amancane naphakathi kuya emigodini ejulile yesisekelo, amaphrojekthi wendawo ebandayo, njll.
Ukusetshenziswa kwezinqwaba zeshidi lensimbi ekuphileni kwansuku zonke
Ukuvikela izindawo zomphakathi nengqalasizinda
Ukuvimbela izikhukhula nokuvikela izindawo ezisogwini: Eceleni kwemifula, amachibi, nogu, izinqwaba zamashidi zakha izindonga zasolwandle, ama-bulkheads, nezithiyo zezikhukhula ezivikela amakhaya, amabhizinisi, nezindawo zomphakathi ekugugulekeni nasekukhuphukeni kwamanzi.
Ukuqinisa amabhuloho nezindlela zemigwaqo: Izinqwaba zamashidi zisetshenziselwa ukwakha nokuqinisa amabhuloho nokuqinisa izindonga zemigwaqo nojantshi. Lokhu kusiza ukuzinzisa ama-embankments nezisekelo, ukuqinisekisa ukuphepha kohambo lwansuku zonke.
Ukwakha izindawo ezingaphansi komhlaba: Izinqwaba zamashidi ensimbi zibalulekile ekwakheni izakhiwo ezingaphansi komhlaba njengemizila engaphansi komhlaba, imigudu yomphakathi, nezindlu zamaphampu ezisetshenziswayo. Banikeza ukwesekwa okubalulekile kokumba futhi bakha umgoqo ongenamanzi wesakhiwo esiphelile.
Ukusekela izakhiwo zezohwebo nezindawo zokuhlala
Izisekelo zokwakha: Ukunqwabelanisa amashidi ensimbi kuvame ukusetshenziselwa ukwakha izindonga eziyisisekelo ezihlala njalo, ikakhulukazi ezakhiweni ezinezindlu zangaphansi noma amagaraji okupaka angaphansi komhlaba. Lokhu kuvamile ezindaweni zasemadolobheni ezinendawo elinganiselwe kanye namatafula aphezulu amanzi.
Ukudala izikhala ezingaphansi kwebanga: Abanikazi bezindlu, ikakhulukazi ezindaweni eziminyene, bangasebenzisa ukunqwabelanisa amashidi ensimbi ukuze bakhe izandiso ezingaphansi komhlaba noma amagumbi angaphansi. Lezi zindonga zinciphisa ukuphazamiseka kwenhlabathi futhi zingenziwa ukuthi zingangeni manzi.
Ukulungiswa nokuvikelwa kwemvelo
Equkethe inhlabathi engcolile: Kumaphrojekthi okuvuselela emadolobheni, izinqwaba zamashidi ensimbi zingashayelwa phansi ukuze kwakhiwe indawo ebiyelwe engangeni. Lokhu kuvimbela ukungcola okuyingozi nezinto ezingcolisiwe ezisemhlabathini ukuthi zingasakazeki.
Ukudala izithiyo zemvelo: Izindonga zenqwaba yamashidi zingasetshenziselwa ukuqukatha izinto eziyingozi futhi zivikele amanzi angaphansi komhlaba ekungcoleni.
Ukusetshenziswa okusha
Izinqwaba zeshidi lamandla: Uhlelo lokusebenza oluvelayo luhlanganisa ukunqwabelana kweshidi lensimbi nezinhlelo zokushintsha ukushisa. Izinqwaba, esezivele ziphansi, zingasetshenziswa ukuthola amandla avela ngaphansi komhlaba ukuze kushise nokupholisa isakhiwo.
Uma kuziwa ekuthengeni izinqwaba ezifanele zeshidi lensimbi, ukukhetha ikhwalithi ephezuluUmkhiqizi Wenqwaba Yeshidi Lensimbiukhiye.
