I-CFG (i-Cement Fly ash Grave) imfumba, eyaziwa ngokuba yi-cement fly ash gravel pile in Chinese, yimfumba yokuqina ephezulu yokudibanisa eyakhiwe ngokuxutywa ngokulinganayo kwesamente, uthuthu lwempukane, igrabile, iitshiphusi zamatye okanye isanti kunye namanzi ngomlinganiselo othile wokuxuba. Yenza isiseko esidibeneyo kunye nomhlaba phakathi kweemfumba kunye ne-cushion layer. Inokusebenzisa ngokupheleleyo amandla emfumba, isebenzise ngokupheleleyo amandla okuthwala iziseko zendalo, kwaye ilungelelanise imathiriyeli yendawo ngokweemeko zendawo. Ineenzuzo zokusebenza okuphezulu, ixabiso eliphantsi, i-deformation encinci yokwakhiwa kwesithuba, kunye nokuzinza ngokukhawuleza. unyango isiseko imfumba CFG iqulathe iinxalenye eziliqela: CFG imfumba umzimba, imfumba cap (ipleyiti), kunye umaleko cushion. Uhlobo lolwakhiwo: imfumba+i-slab, imfumba+ikepusi+umqamelo (le fomu yamkelwe kweli candelo)
1,iteknoloji yokwakha imfumba yeCFG
1. Ukukhethwa kwezixhobo kunye nokufakelwa kweemfumba zeCFG kunokwenziwa kusetyenziswa oomatshini bokugrumba ityhubhu entywiliselwayo okanye oomatshini bokomba bexesha elide. Uhlobo oluthile kunye nemodeli yomatshini wokwenza imfumba oza kusetyenziswa ixhomekeke kwimeko ethile yeprojekthi. Kumhlaba obambeneyo, umhlaba wentlenga, kunye nomhlaba oyintlenga, inkqubo yokubumba imfumba yetyhubhu yokungcangcazela iyamkelwa. Kwiindawo ezineemeko zejoloji zomaleko obunzima bomhlaba, ukusetyenziswa koomatshini bokutshona bokungcangcazela bokwakha kuya kubangela ukungcangcazela okubalulekileyo kwiimfumba esele zenziwe, okukhokelela ekuqhekekeni kwemfumba okanye ukwaphuka. Kwimihlaba enovakalelo oluphezulu, ukungcangcazela kunokubangela ukonakala kolwakhiwo kunye nokuncipha komthamo wokuthwala. I-Spiral drills ingasetyenziselwa ukugrumba imingxunya kwangaphambili, kwaye ityhubhu yokutshona ye-vibration ingasetyenziselwa ukwenza iimfumba. Kwiindawo apho udidi oluphezulu lufuneka khona, umbhobho omde wokugrumba usetyenziselwa ukumpompa nokwenza iimfumba. Eli candelo liyilelwe ukwakhiwa kusetyenziswa umbhobho omde ojikelezayo. Kukwakho neentlobo ezimbini zoomatshini bokwakha bokumpompa ikhonkrithi ngaphakathi kwimibhobho yobhola ejikelezayo emide: uhlobo lokuhamba kunye nohlobo lwesikhasi. Uhlobo lweCrawler oomatshini bokwemba ixesha elide baxhotyiswe ngohlobo lokuhamba ngoomatshini bokwemba bexesha elide. Ngokweshedyuli kunye neemvavanyo zenkqubo, ukucwangciswa kwezixhobo kuphunyezwa kwaye kugcinwe ngexesha elifanelekileyo ukugcina bonke oomatshini bekwimeko eqhelekileyo, ukuhlangabezana neemfuno zokwakha, kwaye kungachaphazeleki inkqubela kunye nomgangatho wokwakha.
2. Ukukhethwa kwezinto kunye nokuxuba ubungakanani bezinto eziluhlaza ezifana nesamente, i-fly ash, ilitye eliqhekeziweyo, kunye nezongezelelo kufuneka zihlangabezane neemfuno kunye nemigangatho efanelekileyo yokwamkelwa komgangatho wezinto eziluhlaza, kwaye zihlolwe ngokungenamkhethe ngokwemigaqo. Yenza iimvavanyo zobungakanani bomxube wangaphakathi ngokweemfuno zoyilo kwaye ukhethe ulungelelwaniso lomxube olufanelekileyo.
2Amanyathelo olawulo lomgangatho weemfumba zeCFG
1. Landela ngokungqongqo umxube wokuyila umxube ngexesha lokwakha, khetha ngokungakhethi iqela leesampulu zekhonkrithi ukusuka kwi-drilling rig nganye kunye nokutshintsha, kwaye usebenzise amandla oxinzelelo njengomgangatho wokumisela amandla omxube;
2. Emva kokuba i-drilling rig ingene kwisayithi, sebenzisa kuqala irula yentsimbi ukujonga ububanzi be-drilling rod ye-drilling rod. Ububanzi bentonga yokubhobhoza kufuneka bungabi ngaphantsi kobubanzi bemfumba yoyilo, kwaye ukuphakama kwenqaba ephambili yesixhobo sokomba kufuneka kube malunga neemitha ezi-5 ngaphezulu kobude bemfumba;
3. Phambi kokugrumba, khulula izikhundla zemfumba yolawulo kwaye unike ingcaciso yobugcisa kubasebenzi bokomba. Abasebenzi bokomba baya kusebenzisa irula yentsimbi ukukhulula indawo nganye yemfumba ngokusekwe kwizikhundla zeemfumba zolawulo.
4. Ngaphambi kokugaya, yenza iimpawu ezicacileyo kwindawo ephambili yenqaba yokugaya i-drilling rig esekelwe kubude obuyilelwe imfumba kunye nobukhulu bentloko yengqungquthela yokukhusela, njengesiseko sokulawula ubunzulu bokugaya i-drilling rig.
5. Emva kokuba i-drilling rig isendaweni, umlawuli uyalela i-drilling rig ukuba ilungelelanise indawo yayo, kwaye isebenzise iimpawu ezimbini zokumakisha ezixhonywe kwisakhelo ukujonga ukuba i-verticality ye-drilling rig ihlangabezana neemfuno;
6. Ekuqaleni kolwakhiwo lwemfumba yeCFG, kukho inkxalabo yokuba imfumba ngolwakhiwo lwemfumba lunokubangela ukugrumba umngxuma. Ngoko ke, indlela yokwakhiwa kwe-interval pile jumping isetyenziswa. Nangona kunjalo, xa kusetyenziswa ukutsiba kweengqumba zekhefu, ipasi yesibini yomqhubi wengqumba endaweni inokubangela lula uxinezeleko kunye nomonakalo kwiimfumba esele zakhiwe. Ke ngoko, ukutsiba kunye nemfumba ngokuqhuba imfumba kufuneka kukhethwe ngokweemeko ezahlukeneyo zejoloji.
7. Xa ugalela ikhonkrithi kwiimfumba zeCFG, uxinzelelo kwiimitha ezingaphezulu ze-1-3 zekhonkrithi ziyancipha, kwaye amaqamza amahle kwikhonkrithi ayinakukhululwa. Inxalenye ephambili yomthwalo wemfumba yeCFG ikwindawo ephezulu, ngoko ke ukunqongophala kokubumbana kwemfumba ephezulu kunokubangela umonakalo kwimfumba ngexesha lokusetyenziswa kobunjineli. Isisombululo kukusebenzisa intonga yokungcangcazela ukudibanisa ikhonkrithi ephezulu emva kokwakhiwa nangaphambi kokuba iqiniswe, ukwenzela ukuqinisa ukudibanisa kwekhonkrithi; Okwesibini kukuqinisa ulawulo lwe-concrete slump, njengoko i-slump encinci inokubangela lula i-honeycomb phenomenon.
8. Ulawulo lwesantya sokutsalwa kombhobho: Ukuba isantya sokutsalwa kombhobho sikhawuleza kakhulu, siya kubangela ukuba idiyamitha yemfumba ibencinci kakhulu okanye ingqumba icuthe kwaye iphuke, ngelixa ukuba isantya sokutsalwa kombhobho sicotha kakhulu, siya kubangela ukungalingani. Ukuhanjiswa kodaka lwesamente, uludaka oludadayo olugqithisileyo kumphezulu wemfumba, ukungonelanga komzimba wemfumba, kunye nokwakheka kokwahlulwa kwezinto ezixubeneyo, okukhokelela ekungoneleni kwamandla emfumba. umzimba. Ngoko ke, ngexesha lokwakha, isantya sokutsala kufuneka silawulwe ngokungqongqo. Isantya sokutsala ngokuqhelekileyo silawulwa kwi-2-2.5m / min, efanelekileyo ngakumbi. Isantya sokutsala apha sisantya somgca, hayi isantya esiphakathi. Ukuba udibana nomhlaba oyintlenga okanye oyintlenga, isantya sokutsala kufuneka sithotywe ngokufanelekileyo. Ukufaka umva akuvumelekanga ngexesha lenkqubo yokukhupha iplagi.
9. Uhlalutyo kunye nonyango lokuqhekeka kwemfumba libhekiselele ekungaqhubekiyo kobuso bekhonkrithi yemfumba yeCFG emva kokuba yenziwe, ngeentanda okanye izikhewu perpendicular kwi-axis esembindini yemfumba embindini. Ukwaphuka kwengqumba yeyona ngozi inkulu esemgangathweni yeemfumba zeCFG. Kukho izizathu ezininzi zokuqhekeka kwemfumba, ikakhulu kubandakanya: 1) ukhuseleko lolwakhiwo olunganelanga, oomatshini abakhulu bokwakha abasebenza kwiindawo zemfumba zeCFG kunye namandla angonelanga, okubangela ukuba imfumba ityunyuzwe okanye intloko yemfumba icunyuzwe; 2) Ivalve yokukhupha i-spiral spiral drilling rig ivaliwe; 3) Xa ugalela ikhonkrithi, ukunikezelwa kwekhonkrithi ukugalelwa akufike ngexesha; 4) Izizathu zokwakheka komhlaba, amanzi amaninzi aphantsi komhlaba, kunye nokuvela lula kokuqhekeka kwemfumba; 5) Ulungelelwaniso olungahambelaniyo phakathi kokutsalwa kombhobho kunye nokupompa ikhonkrithi; 6) Ukusebenza okungafanelekanga ngexesha lokukhutshwa kwentloko yemfumba kubangele umonakalo.
