Intshayelelo yeNdlela yoKwakha
I-rotator ye-casing yi-drill entsha yodidi kunye nokuhlanganiswa kwamandla apheleleyo e-hydraulic kunye nokuhanjiswa, kunye nokulawulwa kokudibanisa komatshini, amandla kunye nolwelo. Bubuchwephesha obutsha, obunobuhlobo nokusingqongileyo nobusebenza kakuhle kakhulu. Kwiminyaka yakutshanje, yamkelwe ngokubanzi kwiiprojekthi ezinje ngolwakhiwo lwendlela yangaphantsi yasezidolophini, imfumba yokudityaniswa kwesiseko somngxuma onzulu, ukucocwa kweemfumba zenkunkuma (izithintelo ezingaphantsi komhlaba), uloliwe ohamba ngesantya esiphezulu, indlela kunye nebhulorho, kunye neemfumba zokwakha ezidolophini, kwakunye nokuqiniswa kwedama lovimba.
Uphando oluyimpumelelo lwale ndlela intsha kraca yenkqubo iye yaqonda amathuba okuba abasebenzi bokwakha baqhube ulwakhiwo lwemibhobho yecasing, ingqumba yokufuduswa, kunye nodonga oluqhubekayo lwangaphantsi komhlaba, kwakunye namathuba okugqobhoza imibhobho kunye netonela ikhaka ukuba lidlule kwi-casing pipe. Iziseko ezahlukeneyo zemfumba ngaphandle kwezithintelo, xa izithintelo, ezinje ngegrabile kunye nokwakhiwa kwamatye, ukubunjwa komqolomba, i-quicksand stratum, ukwakheka kwentamo eyomeleleyo, ukwahlukahlukana. isiseko semfumba kunye nentsimbi eyomeleziweyo yesakhiwo sekhonkrithi, ayisuswa.
Indlela yokwakha ye-casing rotator igqibe ngempumelelo imisebenzi yokwakha yeeprojekthi ezingaphezu kwama-5000 kwiindawo zaseSingapore, eJapan, kwiSithili saseHongkong, eShanghai, eHangzhou, eBeijing naseTianjin. Ngokuqinisekileyo iya kudlala indima enkulu kulwakhiwo lwasezidolophini lwexesha elizayo kunye namanye amasimi olwakhiwo lwesiseko semfumba.
( 1 ) Imfumba yesiseko, udonga oluqhubekayo
Iimfumba zesiseko kuloliwe ohamba ngesantya esiphezulu, indlela kunye nebhulorho kunye nokwakhiwa kwezindlu.
Ulwakhiwo lwemfumba edityanisiweyo ekufuneka igrunjwe, efana namaqonga kaloliwe ongaphantsi komhlaba, ulwakhiwo oluphantsi komhlaba, iindonga eziqhubekayo.
Udonga olugcina amanzi lokuqiniswa kwedama.
( 2 ) Ukugrumba iigrabile, amatye kunye nemiqolomba yekarst
Kuvumelekile ukuqhuba ulwakhiwo lwemfumba yesiseko kwiindawo ezisezintabeni ezinegrabile kunye nokwakheka kwamatye.
Kuvumelekile ukuqhuba umsebenzi kunye nokuphosa iimfumba zesiseko ekubunjweni kwesanti eshinyeneyo kunye nokufaka intamo phantsi kwestratum okanye umaleko wokuzalisa.
Qhuba ukomba olunesiseko samatye kwi-rock stratum, phosa imfumba yesiseko.
( 3 ) Sula imiqobo engaphantsi komhlaba
Ngexesha lokwakhiwa kwedolophu kunye nokwakhiwa kwebhulorho kwakhona, izithintelo ezifana nentsimbi eyomeleziweyo yekhonkrithi, inqwaba yombhobho wensimbi, i-H steel pile, i-pc pile kunye nemfumba yokhuni inokucocwa ngokuthe ngqo, kwaye iphose imfumba yesiseko kwindawo leyo.
( 4 ) Sika ilitye
Ukuqhuba ukomba olunesiseko samatye kwiimfumba ezifakwe kwindawo.
Gcoba imingxunya kumandlalo wamatye (iishafti kunye nemingxuma yokuphefumla)
( 5 ) Ukwemba nzulu
Yenza i-in-place casting okanye i-steel pipe ifake imfumba yokuphucula isiseko esinzulu.
Ukugrumba amaqula anzulu ukuze asetyenziswe kulwakhiwo lwedama kunye netonela.
Iinzuzo zokwamkela i-casing rotator yokwakha
1) Akukho ngxolo, akukho vibration, kunye nokhuseleko oluphezulu;
I-2) Ngaphandle kodaka, indawo yokusebenza ecocekileyo, ubuhlobo obuhle bokusingqongileyo, ukuphepha ukuba kunokwenzeka ukuba udaka lungene kwikhonkrithi, umgangatho ophezulu wemfumba, ukunyusa uxinzelelo lwebhondi yekhonkrithi kwintsimbi yentsimbi;
3) Ngexesha lokugaya ukwakhiwa, iimpawu ze-stratum kunye nelitye zinokuhlukaniswa ngokuthe ngqo;
4)Isantya sokomba siyakhawuleza kwaye sifikelela malunga ne-14m/h kumaleko omhlaba jikelele;
5)Ubunzulu bokomba bukhulu kwaye bufikelela malunga ne-80m ngokwemeko yomaleko womhlaba;
6) Umngxuma owenza ukuqina kulula ukuwuqonda, onokuchaneka kwi-1/500;
7) Akukho kudilika komngxuma kuya kubangelwa, kwaye umgangatho wokwenza umngxuma uphezulu.
I-8) I-diameter eyenza umngxuma isemgangathweni, kunye neyona nto incinci yokuzalisa. Xa ithelekiswa nezinye iindlela zokubumba umngxuma, inokonga ukusetyenziswa kwekhonkrithi okuninzi;
I-9) Ukucocwa komngxuma kucokisekileyo kwaye kuyakhawuleza. Udaka lokugrumba kumngxuma ongezantsi lunokucaca ukuya kwi-3.0cm.
