1. Ukwakhiwa kwetshe elichotshoziwe lomlotha we-cement fly kufanele kulandele izidingo zomklamo kanye nezimo zendawo, futhi kuhambisane nezindinganiso zamanje zikazwelonke: (1) Izinqwaba zokubhoboza ezinde ezijikelezayo kanye nezingcezu zokugxusha zifanele inhlabathi ehlangene, inhlabathi enodaka, kanye nezisekelo zokugcwalisa ezenziwe ngaphezu kwezinga lamanzi angaphansi komhlaba; (2) Ukubhoboza odongeni oluthambile kanye nezingcezu zokugxusha zifanele inhlabathi ehlangene, inhlabathi enodaka, inhlabathi yesihlabathi, inhlabathi yokugcwalisa eyenziwe, inhlabathi enamatshe, kanye nezendlalelo zamadwala ezigugile; (3) Izinqwaba zezinto ezixubile zokubhoboza ezijikelezayo kanye nokucindezela ipayipi zifanele inhlabathi ehlangene, inhlabathi enodaka, inhlabathi yesihlabathi, kanye nezinye izisekelo, kanye nezindawo ezinomsindo oqinile kanye nezidingo zokulawula ukungcola kodaka; (4) Izinqwaba zokucwila kanye nezingcezu zokugxusha zifanele inhlabathi ehlangene, inhlabathi enodaka, inhlabathi yokugcwalisa eyenziwe, kanye nezendlalelo zesihlabathi esiqinile esingaxinene.
2. Ngaphezu kokuhambisana nezindinganiso zamanje zikazwelonke, ukwakhiwa kwezinqwaba zezinto ezixubile zokubhoboza ezinde ezijikelezayo kanye nezinqwaba zezinto ezixubile zephampu yangaphakathi, kanye nezinqwaba zokucwilisa amaphampu kanye nezinqwaba ze-grouting, kufanele futhi kuhlangatshezwane nezidingo ezilandelayo: (1) Ngesikhathi sokwakha, izinto ezixubile kufanele zilungiswe ngokwesilinganiso sokuklama. Inani lamanzi angeziwe ku-mixer lilawulwa ukucwilisa kwezinto ezixubile. Ekwakhiweni kwezinqwaba zezinto ezixubile zokubhoboza ezijikelezayo kanye nezinqwaba zephampu yangaphakathi, ukucwilisa kufanele kube ngu-180-200mm, kanti ekwakhiweni kwezinqwaba zokucwilisa amaphampu kanye nezinqwaba ze-grouting, kufanele kube ngu-30-50mm. Ngemva kokwakheka kwezinqwaba, ubukhulu be-slurry entantayo phezulu kwenqwaba akufanele kudlule u-200mm; (2) Ngemva kokubhoboza ekujuleni okuklanyelwe, ekwakhiweni kwezinqwaba zezinto ezixubile zokubhoboza ezijikelezayo kanye nezinqwaba zephampu yangaphakathi, isikhathi sokuphakamisa induku yokubhoboza kumele silawulwe ngokunembile. Umthamo wezinto ezixubile ezipompiwe kufanele uhambisane nesivinini sokudonsa iphampu ukuqinisekisa ukuthi ukuphakama okuthile kwezinto ezixubile kuhlala ephayiphini. Uma uhlangana nesihlabathi esigcwele noma izendlalelo ze-silt ezigcwele, ipompo akufanele imiswe ukuze kulindelwe izinto ezengeziwe. Ngokwakhiwa kwenqwaba yokucwilisa ipayipi nokufaka i-grouting, isivinini sokudonsa ipayipi kufanele silawulwe ngesivinini esijwayelekile somugqa, isivinini sokudonsa ipayipi silawulwa cishe ku-1.2-1.5m/min. Uma uhlangana nomhlabathi wodaka noma we-silt, isivinini sokudonsa ipayipi singancishiswa ngokufanele; (3) Ngesikhathi sokwakha, ukuphakama kwenqwaba kufanele kube phezulu kunokuphakama kwenqwaba okuklanyelwe. Ukuphakama ngaphezu kokuphakama kwenqwaba okuklanyelwe kufanele kunqunywe ngokusekelwe esikhaleni senqwaba, ifomu lokuhlelwa kwenqwaba, izimo zejiyoloji yendawo, kanye nokulandelana kokwakheka kwenqwaba, ngokuvamile kungabi ngaphansi kuka-0.5m; (4) Ngesikhathi sokwakhiwa kwenqwaba, amasampula ezinto ezixubile kufanele athathwe ukuze kwenziwe amabhlogo okuhlola. Umshini ngamunye kufanele ukhiqize isethi eyodwa (amabhlogo amathathu) amabhlogo okuhlola (ama-cubes anobude obuyi-150mm) ngosuku, okufanele aphathwe ngendlela ejwayelekile imizuzu engama-28, futhi amandla awo okucindezela kufanele alinganiswe; (5) Ngesikhathi sokwakhiwa kwenqwaba yokuthulula amapayipi, kufanele kuqashelwe ukuthi izinqwaba ezisanda kwakhiwa zithinta kanjani izinqwaba ezakhiwe kakade. Uma kutholakala ukuthi izinqwaba ziyaphuka futhi ziyahlukana, izinqwaba zobunjiniyela kumele zibe nengcindezi engaguquki ngayinye ngayinye. Isikhathi sokucindezela okungaguquki ngokuvamile siyimizuzu emi-3, futhi umthwalo wokucindezela ongaguquki uyadingeka ukuqinisekisa ukuthi izinqwaba eziphukile zixhunyiwe.
3. Umgodi wesisekelo sesisekelo esihlanganisiwe ungambiwa ngezindlela zesandla noma zemishini, noma inhlanganisela yezindlela zesandla nezemishini. Lapho ukumbiwa kwemishini kanye nezandla kuhlanganiswa, ubukhulu bokumbiwa ngesandla okugciniwe kufanele kunqunywe ngokumbiwa endaweni ukuqinisekisa ukuthi ingxenye yokuqhekeka ebangelwa ukumbiwa kwemishini ayiphansi kunokuphakama kwesisekelo, futhi inhlabathi ephakathi kwezinqwaba ayiphazanyiswa.
4. Indlela yokuqinisa engaguquki kufanele isetshenziswe ekubekeni ungqimba lomcamelo. Uma okuqukethwe kwamanzi enhlabathini phakathi kwezinqwaba ngaphansi kobuso obuphansi besisekelo kuncane, indlela yokuqinisa enamandla nayo ingasetshenziswa.
5. Ngesikhathi sokwakha, ukuphambuka okuvumelekile kobude benqwaba kungu-100mm, ububanzi benqwaba bungu-20mm, kanti ukuma kungu-1%. Ngesisekelo esigcwele esinezinqwaba ezibekwe emgqeni owodwa, ukuphambuka okuvumelekile kwezikhundla zenqwaba kuphindwe ka-0.5 ububanzi benqwaba; ngesisekelo somugqa, ukuphambuka okuvumelekile kwezikhundla zenqwaba kuqonde ngqo ku-axis kuphindwe ka-0.25 ububanzi benqwaba, kanti ngendlela ehambisana ne-axis, kuphindwe ka-0.3 ububanzi benqwaba. Ukuphambuka okuvumelekile kwezikhundla zenqwaba emgqeni owodwa wezinqwaba akumele kudlule u-60mm.
