Inqwaba ye-CFG (Cement Fly ash Grave), eyaziwa nangokuthi inqwaba ye-cement fly ash gravel ngesiShayina, iyinqwaba yamandla esibopho eyakhiwe ngokuxubana ngokulinganayo usimende, umlotha womlotha, amatshe, amatshe amatshe noma isihlabathi namanzi ngesilinganiso esithile sokuxuba. Yakha isisekelo esiyinhlanganisela kanye nomhlabathi phakathi kwezinqwaba kanye nongqimba lwe-cushion. Ingasebenzisa ngokugcwele amandla ezinto eziyinqwaba, isebenzise ngokugcwele amandla okuthwala ezisekelo zemvelo, futhi ivumelanise izinto zasendaweni ngokwezimo zendawo. Inezinzuzo zokusebenza kahle okuphezulu, izindleko eziphansi, ukuwohloka okuncane kokwakhiwa kweposi, nokuzinza kokuxazulula ngokushesha. CFG inqwaba isisekelo ukwelashwa siqukethe izingxenye eziningana: CFG inqwaba umzimba, inqwaba cap (ipuleti), futhi umcamelo ungqimba. Uhlobo lwesakhiwo: inqwaba+i-slab, inqwaba+cap+umcamelo ungqimba (leli fomu lamukelwa kulesi sigaba)
1,Ubuchwepheshe bokwakha inqwaba ye-CFG
1. Ukukhethwa kwemishini kanye nokufakwa kwezinqwaba ze-CFG kungenziwa kusetshenziswa imishini yokumba amashubhu edidiyelwe noma imishini emide evunguzayo yokumba. Uhlobo oluthile kanye nemodeli yemishini yokwenza inqwaba ezosetshenziswa incike esimweni esithile sephrojekthi. Ukuze uthole inhlabathi ehlangene, inhlabathi ye-silt, nenhlabathi enodaka, kwamukelwa inqubo yokwakhiwa kwenqwaba yamashubhu okudlidliza. Ezindaweni ezinezimo ze-geological zezendlalelo zenhlabathi eqinile, ukusetshenziswa kwemishini yokucwilisa i-vibration yokwakha kuzobangela ukudlidliza okuphawulekayo ezinqwabeni ezakhiwe kakade, okuholela ekuqhekekeni kwenqwaba noma ukuphuka. Emhlabathini onokuzwela okuphezulu, ukudlidliza kungabangela ukulimala kwamandla esakhiwo kanye nokuncipha kwamandla okuzala. Ama-spiral drill angasetshenziselwa ukubhoboza izimbobo ngaphambili, bese kuthi ishubhu lokuzamazama lisetshenziswe ukwenza izinqwaba. Ezindaweni lapho kudingeka khona ukubhola kwekhwalithi ephezulu, ipayipi elide lokumba elivunguzayo lisetshenziselwa ukumpompa nokwenza izinqwaba. Lesi sigaba siklanyelwe ukwakhiwa kusetshenziswa i-spiral drilling rig ende. Kukhona futhi izinhlobo ezimbili zemishini yokwakha yokumpompa ukhonkolo ngaphakathi kwamapayipi okubhola okuvunguzayo amade: uhlobo oluhambayo kanye nohlobo lokukhasa. Imishini yokumba evunguzayo yohlobo lweCrawler ifakwe uhlobo olude lwemishini yokumba evunguzayo. Ngokweshejuli nokuhlolwa kwenqubo, ukucushwa kwemishini kusetshenziswa futhi kugcinwa ngesikhathi ukuze kugcinwe yonke imishini isesimweni esijwayelekile, ihlangabezane nezidingo zokwakha, futhi ingaphazamisi inqubekelaphambili nekhwalithi yokwakha.
2. Ukukhethwa kwezinto zokwakha kanye nezilinganiso zokuxutshwa kwezinto ezingavuthiwe ezifana usimende, umlotha wempukane, itshe elichotshoziwe, nezithasiselo kufanele kuhlangabezane nezidingo kanye nezindinganiso ezifanele zokwamukelwa kwekhwalithi yezinto ezingavuthiwe, futhi zihlolwe ngokungahleliwe ngokuvumelana nemithethonqubo. Yenza ukuhlolwa kwesilinganiso sengxube yasendlini ngokuya ngezidingo zedizayini bese ukhetha izilinganiso ezifanele zokuhlanganisa.
2,Izinyathelo zokulawula ikhwalithi ze-CFG piles
1. Landela ngokuqinile isilinganiso senhlanganisela yokuklama ngesikhathi sokwakha, khetha ngokungahleliwe iqoqo lezibonelo zikakhonkolo ku-drilling rig ngayinye kanye ne-shift, futhi usebenzise amandla okucindezela njengezinga lokunquma amandla engxube;
2. Ngemva kokuba i-rig yokumba ingene endaweni, qala usebenzise irula yensimbi ukuze uhlole ububanzi benduku yokubhoboza ye-drilling. Ububanzi benduku yokubhoboza akufanele bube ngaphansi kobubanzi benqwaba yokuklama, futhi ukuphakama kombhoshongo oyinhloko we-drilling kufanele kube ngamamitha angu-5 mkhulu kunobude benqwaba;
3. Ngaphambi kokumba, khulula izindawo zokulawula inqwaba futhi unikeze ulwazi lobuchwepheshe kubasebenzi bokumba. Izisebenzi zokumba zizosebenzisa irula yensimbi ukuze zikhulule indawo ngayinye yenqwaba ngokusekelwe ezindaweni zokulawula inqwaba.
4. Ngaphambi kokumba, yenza izimpawu ezicacile endaweni eyinhloko yombhoshongo we-drilling rig esekelwe ubude benqwaba eklanyelwe kanye nobukhulu bengqimba yokuzivikela yekhanda lenqwaba, njengesisekelo sokulawula ukujula kokumba kwe-drilling rig.
5. Ngemva kokuba i-rig yokumba isisendaweni, umlawuli uyala i-rig yokubhoboza ukuthi ilungise indawo yayo, futhi isebenzisa izimpawu ezimbili eziqondile ezilenga kuhlaka ukuze anqume ukuthi ukuma kwe-drilling rig kuyahlangabezana yini nezidingo;
6. Ekuqaleni kokwakhiwa kwenqwaba ye-CFG, kunokukhathazeka ukuthi inqwaba ngokwakhiwa kwenqwaba ingase ibangele ukubhobozwa kwemigodi. Ngakho-ke, kusetshenziswa indlela yokwakha ye-interval pile jumping. Nokho, lapho kusetshenziswa i-interval pile jumping, iphasi yesibili yomshayeli wenqwaba esendaweni ingase ibangele kalula ukucindezelwa kanye nokulimala kwezinqwaba ezakhiwe kakade. Ngakho-ke, ukugxuma nokunqwabelana ngokushayela inqwaba kufanele kukhethwe ngokuya ngezimo ezihlukene ze-geological.
7. Lapho uthela ukhonkolo ezinqwabani ze-CFG, ingcindezi engaphezulu kwamamitha angu-1-3 kakhonkolo iyancipha, futhi ama-bubbles amahle kukhonkolo awakwazi ukukhululwa. Ingxenye eyinhloko ethwala imithwalo ye-CFG iyingxenye engenhla, ngakho ukuntuleka kokubumbana kwenqwaba yomzimba kungabangela kalula ukulimala kwenqwaba ngesikhathi sokusetshenziswa kobunjiniyela. Isixazululo siwukusebenzisa induku yokudlidliza ukuze uhlanganise ukhonkolo ongaphezulu ngemva kokwakhiwa nangaphambi kokuba uqine, ukuze kuqiniswe ukuhlangana kokhonkolo; Okwesibili ukuqinisa ukulawula ukwehla kukakhonkolo, njengoba ukuwohloka okuncane kungabangela kalula i-honeycomb.
8. Ukulawulwa kwezinga lokudonsa kwamapayipi: Uma izinga lokudonsa ipayipi lishesha kakhulu, lizokwenza ukuthi ububanzi benqwaba lube luncane kakhulu noma inqwaba ishwabane futhi iphuke, kanti uma izinga lokudonsa kwamapayipi lihamba kancane, lizodala ukungalingani. ukusatshalaliswa kodaka lukasimende, udaka oluntantayo oluningi phezu kwenqwaba, amandla anganele omzimba wenqwaba, nokwakheka kokuhlukaniswa kwezinto ezixubile, okuholela ekungeneni kwamandla enqwaba. umzimba. Ngakho-ke, ngesikhathi sokwakhiwa, isivinini sokudonsa kufanele silawulwe ngokuqinile. Ijubane lokudonsa livamise ukulawulwa ku-2-2.5m/min, okuyilona elifaneleka kakhulu. Isivinini sokudonsa lapha isivinini esiwumugqa, hhayi isivinini esimaphakathi. Uma uhlangana nenhlabathi enodaka noma enodaka, ijubane lokudonsa kufanele lehliswe ngendlela efanele. Ukufaka ukuhlehla akuvunyelwe phakathi nenqubo yokukhipha i-plug.
9. Ukuhlaziywa kanye nokwelashwa ukuphuka inqwaba libhekisela discontinuity ebusweni ukhonkolo inqwaba CFG ngemva kwakhiwa, nemifantu noma izikhala perpendicular kuya eksisi emaphakathi inqwaba phakathi. Ukuphuka kwenqwaba ingozi enkulu yekhwalithi yama-CFG piles. Kunezizathu eziningi zokuqhekeka kwenqwaba, ikakhulukazi okuhlanganisa: 1) ukuvikelwa kokwakhiwa okunganele, imishini emikhulu yokwakha esebenza ezindaweni zenqwaba ye-CFG enamandla anganele, okubangela ukuthi inqwaba igaywe noma ikhanda lenqwaba lichotshozwe; 2) I-valve yokukhipha insimbi ende yokumba evunguzayo ivinjiwe; I-3) Lapho uthela ukhonkolo, ukunikezwa kokuthulula ukhonkolo akufike ngesikhathi; 4) Izizathu zokuma komhlaba, amanzi amaningi angaphansi komhlaba, kanye nokuvela kalula kokuphuka kwenqwaba; 5) Ukuxhumana okungahambisani phakathi kokudonsa kwamapayipi kanye nokupompa ukhonkolo; I-6) Ukusebenza okungalungile ngesikhathi sokususwa kwekhanda lenqwaba kubangele umonakalo.
