1. Ukwakhiwa kwelitye elityumkileyo lesamente kufuneka kulandele iimfuno zoyilo kunye neemeko zendawo, kwaye kuhambelane nemigangatho yangoku yesizwe: (1) Iinqwaba ezinde zokubhola ezijikelezayo kunye neengceba zifanelekile kumhlaba odibeneyo, umhlaba omdaka, kunye neziseko zokuzalisa ezenziweyo ezingaphezulu komgangatho wamanzi angaphantsi komhlaba; (2) Iinqwaba zokubhola eludongeni kunye neengceba ezijikelezayo zifanelekile kumhlaba odibeneyo, umhlaba omdaka, umhlaba onesihlabathi, umhlaba ozaliswe ngokwenziwa, umhlaba onamabala, kunye neengqimba zamatye ezigugileyo; (3) Iinqwaba zezinto ezixutyiweyo zokubhola ezijikelezayo kunye nokucinezela ipayipi zifanelekile kumhlaba odibeneyo, umhlaba omdaka, umhlaba onesihlabathi, kunye nezinye iziseko, kunye neendawo ezineemfuno zokulawula ungcoliseko olungqongqo kunye nodaka; (4) Iinqwaba zokucwila kunye neengceba ezijikelezayo zifanelekile kumhlaba odibeneyo, umhlaba omdaka, umhlaba ozaliswe ngokwenziwa, kunye neengqimba zesanti ezixineneyo ezingaxinenanga.
2. Ukongeza ekuthobeleni imigangatho yesizwe yangoku, ukwakhiwa kweenqwaba zezinto ezixutyiweyo ezijikelezayo ezinde kunye neepayipu zangaphakathi, kunye neenqwaba zokusinkisha iipayipu kunye nee-grouting, kufuneka zihlangabezane neemfuno ezilandelayo: (1) Ngexesha lokwakha, izinto ezixutyiweyo kufuneka zilungiswe ngokomlinganiselo woyilo. Ubungakanani bamanzi obongezwe kwi-mixer bulawulwa kukudilika kwezinto ezixutyiweyo. Kwi-long spiral drilling kunye ne-pipe internal pump pressure mixed material, ukudilika kufuneka kube yi-180-200mm, ngelixa kwi-pipe sinking kunye ne-grouting pile, kungcono ukuba ibe yi-30-50mm. Emva kokwenziwa kweenqwaba, ubukhulu be-slurry edadayo phezulu kwenqwaba akufuneki idlule kwi-200mm; (2) Emva kokugrumba ukuya kubunzulu obuyiliweyo, kwi-long spiral drilling kunye ne-pipe internal pump pressure mixed material, ixesha lokuphakamisa intonga yokugrumba kufuneka lilawulwe ngokuchanekileyo. Umthamo wezinto ezixutyiweyo ezipompelwayo kufuneka uhambelane nesantya sokutsala ipayipu ukuqinisekisa ukuba ukuphakama okuthile kwezinto ezixutyiweyo kuhlala kumbhobho. Ukuba udibana nesanti exineneyo okanye iileya zedaka eligcweleyo, ipompo akufuneki imiswe ukuze kulindelwe ezinye izinto. Kwindawo yokwakhiwa kweenqwaba zokucwila kunye nokwakhiwa kweengqokelela zemibhobho, isantya sokutsala imibhobho kufuneka silawulwe ngesantya esiqhelekileyo somgca, isantya sokutsala imibhobho silawulwa malunga ne-1.2-1.5m/min. Ukuba udibana nomhlaba wodaka okanye wedaka, isantya sokutsala imibhobho sinokuncitshiswa ngokufanelekileyo; (3) Ngexesha lokwakha, ukuphakama kwephezulu kweenqwaba kufuneka kube phezulu kunokuphakama kwephezulu kweenqwaba okuyilwe. Ukuphakama ngaphezu kokuphakama kwephezulu kweenqwaba okuyilwe kufuneka kumiselwe ngokusekwe kwisithuba seenqwaba, imo yoyilo lweenqwaba, iimeko zejoloji yendawo, kunye nolandelelwano lokwakheka kweenqwaba, ngokubanzi kungabi ngaphantsi kwe-0.5m; (4) Ngexesha lokwakheka kweenqwaba, kufuneka kuthathwe iisampulu zezinto ezixutyiweyo ukwenza iibhloko zovavanyo. Umatshini ngamnye kufuneka uvelise iseti enye (iibhloko ezi-3) zeebhloko zovavanyo (iityhubhu ezinobude obusecaleni be-150mm) ngosuku, ekufuneka zilungiswe ngokwesiqhelo kangange-28d, kwaye amandla azo oxinzelelo kufuneka alinganiswe; (5) Ngexesha lokwakhiwa kwenqwaba yokuthulula imibhobho, kufuneka kujongwe impembelelo yeenqwaba ezisandula ukwakhiwa kwiinqwaba esele zakhiwe. Xa inqwaba ifunyenwe iqhekeka kwaye iphuma, iinqwaba zobunjineli kufuneka zibe noxinzelelo olungaguqukiyo nganye nganye. Ixesha loxinzelelo olungaguqukiyo ngokubanzi yimizuzu emi-3, kwaye umthwalo woxinzelelo olungaguqukiyo uyafuneka ukuqinisekisa ukuba iinqwaba eziphukileyo ziqhagamshelwe.
3. Umngxuma wesiseko sesiseko esidityanisiweyo unokugrunjwa ngeendlela ezisetyenziswa ngesandla okanye ngoomatshini, okanye indibaniselwano yeendlela ezisetyenziswa ngesandla nezisetyenziswa ngesandla. Xa kudityaniswe ukugrunjwa ngoomatshini nangoomatshini, ubukhulu bokugrunjwa ngesandla obugciniweyo kufuneka bumiselwe ngokugrunjwa kwindawo ukuqinisekisa ukuba inxalenye yokuqhekeka ebangelwe kukugrunjwa ngoomatshini ayingaphantsi kokuphakama kwesiseko, kwaye umhlaba ophakathi kweenqwaba awuphazanyiswa.
4. Indlela yokuxinana engashukumiyo mayisetyenziswe xa kubekwa umaleko womqamelo. Xa umthamo wamanzi womhlaba phakathi kweenqwaba ezingaphantsi komphezulu osezantsi wesiseko umncinci, indlela yokuxinana enamandla nayo ingasetyenziswa.
5. Ngexesha lokwakha, ukuphambuka okuvumelekileyo kobude benqwaba yi-100mm, ububanzi benqwaba yi-20mm, kwaye ukuthe nkqo yi-1%. Kwisiseko esipheleleyo esineenqwaba ezibekwe kumqolo omnye, ukuphambuka okuvumelekileyo kwezikhundla zeenqwaba kuphindwe ka-0.5 ububanzi benqwaba; kwisiseko somcu, ukuphambuka okuvumelekileyo kwezikhundla zeenqwaba kuthe nkqo kwi-axis kuphindwe ka-0.25 ububanzi benqwaba, kwaye kwicala elisecaleni kwe-axis, kuphindwe ka-0.3 ububanzi benqwaba. Ukuphambuka okuvumelekileyo kwezikhundla zeenqwaba kumqolo omnye weenqwaba akufuneki kudlule kwi-60mm.
