中文MJS indlela imfumba(INkqubo yeJet yeMetro), eyaziwa ngokuba yindlela yokujetha yoxinzelelo olujikelezayo, yaphuhliswa ekuqaleni ukusombulula iingxaki zokukhutshwa kodaka kunye nefuthe lokusingqongileyo kwinkqubo yokwakhiwa kwejethi ejikelezayo ethe tyaba. Okwangoku isetyenziswa kakhulu kunyango lwesiseko, unyango lokuvuza kunye neengxaki zomgangatho wesiseko somngxuma ogcina umkhusane wokumisa amanzi, kunye nokunyangwa kwamanzi amdaka kudonga lwangaphandle lwesakhiwo esingaphantsi. Ngenxa yokusetyenziswa kwemibhobho enemingxuma eyodwa kunye nesiphelo sangaphambili ngenkani izixhobo zokufunxa uludaka, ukukhutshwa ngenkani kumngxunya kunye nokujongwa koxinzelelo lomhlaba kuyenzeka, kwaye uxinzelelo lomhlaba lulawulwa ngokuhlengahlengisa umthamo wokukhupha ukunyanzeliswa kodaka, ukuze ukukhutshwa kodaka olunzulu kunye uxinzelelo lomhlaba lulawulwa ngokufanelekileyo, kwaye uxinzelelo lomhlaba luzinzisiwe, okunciphisa amathuba okutshatyalaliswa kwendawo ngexesha lokwakha kwaye kunciphisa kakhulu impembelelo kwindalo. Ukuncitshiswa koxinzelelo lwasemhlabeni kwakhona kuqinisekisa ngakumbi ububanzi bengqumba.
Ulawulo lwangaphambili
Ukususela kwiMJS imfumbaitekhnoloji yokwakha inzima kakhulu kwaye inzima ngakumbi kunezinye iindlela zokugaya, kuyafuneka ukuba ulandele ngokungqongqo iimfuno zoyilo ngexesha lenkqubo yokwakha, wenze umsebenzi olungileyo wokuhambelana nenkcazo yobugcisa kunye nokhuseleko, kwaye uthobele iinkqubo zokusebenza ezihambelanayo zokuqinisekisa umgangatho wokwakha. .
Emva kokuba i-drilling rig isendaweni, indawo yemfumba kufuneka ilawulwe kakuhle. Ngokuqhelekileyo, ukuphambuka ukusuka kwindawo yokuyila akufanele kudlule i-50mm, kwaye ukuphambuka okuthe tye akufanele kudlule i-1/200.
Ngaphambi kokwakhiwa ngokusesikweni, uxinzelelo kunye nokuhamba kwamanzi aphezulu-uxinzelelo, ipompo yoxinzelelo oluphezulu kunye ne-compressor yomoya, kunye nesantya sokuphakamisa, umthamo we-grouting, kunye neemeko zokugqibela zomngxuma wombhobho we-grouting ngexesha lenkqubo yokujova inqunywe ngovavanyo. iimfumba. Ngethuba lolwakhiwo olusesikweni, i-console yolawulo ephakathi ingasetyenziselwa ukulandelela kunye nokulawula ngokuzenzekelayo. Yenza iirekhodi ezicacileyo zeerekhodi ezahlukeneyo zokwakha kwisiza, kubandakanywa: ukuthambekela kokomba, ubunzulu bokomba, imiqobo yokubhoboza, ukuwa, iiparameters zokusebenza ngexesha lokutofa kwe-slurry, ukubuya kwe-slurry, njl., kwaye ushiye idatha ephambili yomfanekiso. Kwangaxeshanye, iingxelo zokwakha zifanele zilungiswe kwangethuba, yaye iingxaki zifanele zixelwe zize zisingathwe kwangethuba.
Ukuqinisekisa ukuba akukho ngqumba yokwaphuka xa intonga ye-drill ichithwa okanye umsebenzi uphazamiseka ixesha elide ngenxa yezizathu ezithile, ubude bokudityaniswa kweemfumba eziphezulu nezisezantsi azikho ngaphantsi kwe-100mm xa inaliti eqhelekileyo iphinda iqaliswe. .
Gcina oomatshini bokwakha phambi kokwakha ukunciphisa iingxaki zomgangatho ezibangelwa kukusilela kwesixhobo ngexesha lokwakha. Ukuqhuba uqeqesho lwangaphambi kolwakhiwo lwabaqhubi boomatshini ukuze baziqhelanise neendawo zokusebenza kunye neendawo zokusebenza kwezixhobo. Ngexesha lokwakha, umntu ozinikeleyo unoxanduva lokusebenza kwesixhobo.
Ukuhlolwa phambi kokwakhiwa
Ngaphambi kokwakhiwa, imathiriyeli ekrwada, oomatshini kunye nezixhobo, kunye nenkqubo yokutshiza kufuneka ihlolwe, ngakumbi kule miba ilandelayo:
1 Izatifikethi zomgangatho kunye neengxelo zovavanyo lwamangqina ezinto ezahlukeneyo eziluhlaza (kubandakanywa nesamente, njl. njl.), ukuxuba amanzi kufuneka ahlangabezane nemimiselo ehambelanayo;
2 Ingaba umlinganiselo womxube we-slurry ufanelekile kwiimeko zomhlaba zeprojekthi;
3 Ingaba oomatshini kunye nezixhobo ziqhelekileyo. Ngaphambi kokwakhiwa, i-MJS yonke into ejikelezayo ye-jet ye-jet ye-high-pressure high-pressure, i-hole drilling rig, i-high-pressure yepompo yodaka, imvelaphi yokuxuba i-slurry, impompo yamanzi, njl. , i-drill bit kunye nesixhobo sesikhokelo kufuneka singaphazanyiswa;
4 Jonga ukuba inkqubo yokutshiza ifanelekile na kwiimeko zejoloji. Ngaphambi kokwakhiwa, inkqubo yokutshiza uvavanyo kufuneka kwakhona iqhutywe. Uvavanyo lokutshiza kufuneka lwenziwe kwindawo yokuqala yemfumba. Inani lemingxuma yemfumba yokutshiza yovavanyo kufuneka ingabi ngaphantsi kwemingxuma emi-2. Ukuba kuyimfuneko, lungisa iiparamitha zenkqubo yokutshiza.
5 Ngaphambi kokwakhiwa, imiqobo engaphantsi komhlaba kufuneka ihlolwe ngokufanayo ukuze kuqinisekiswe ukuba ukugaya kunye nokutshiza kuyahlangabezana neemfuno zokuyila.
6 Jonga ukuchaneka kunye novakalelo lwendawo yemfumba, igeyiji yoxinzelelo kunye nemitha yokuhamba kwamanzi phambi kokwakhiwa.
Ulawulo lwenkqubo
Ngexesha lenkqubo yokwakha, oku kulandelayo kufuneka kuthathelwe ingqalelo:
I-1 Jonga i-verticality ye-drill rod, isantya sokomba, ubunzulu bokomba, isantya sokomba kunye nesantya sokujikeleza nangaliphi na ixesha ukubona ukuba ziyahambelana neemfuno zengxelo yovavanyo lwemfumba;
2 Qwalasela umlinganiselo we-sement slurry mix ratio kunye nomlinganiselo wezinto ezahlukeneyo kunye ne-admixtures, kwaye urekhode ngokunyanisekileyo uxinzelelo lwenaliti, isantya sokutofa kunye nomthamo wenaliti ngexesha le-injection grouting;
3 Enoba iirekhodi zokwakha zigqityiwe. Iirekhodi zokwakha kufuneka zirekhode idatha yoxinzelelo kunye nokuhamba kanye rhoqo kwi-1m yokuphakanyiswa okanye ekudibaneni komgangatho womhlaba utshintsho, kwaye ushiye idatha yemifanekiso ukuba kuyimfuneko.
Emva kokulawula
Emva kokuba ukwakhiwa kugqityiwe, umhlaba oqiniweyo kufuneka uhlolwe, kubandakanywa: ukunyaniseka kunye nokufana komhlaba odibeneyo; ububanzi obusebenzayo bomhlaba odibeneyo; amandla, i-avareji yedayamitha, kunye nesithuba semfumba seziko lomhlaba odityanisiweyo; ukunganyameki komhlaba odibeneyo, njl.
1 Ixesha lokuhlola umgangatho kunye nomxholo
Ekubeni ukuqina komhlaba we-samente kufuna ixesha elithile, ngokubanzi ngaphezu kweentsuku ezingama-28, iimfuno ezithile kufuneka zisekelwe kumaxwebhu oyilo. Ngoko ke, ukuhlolwa komgangatho weUkutshiza kwe-MJSukwakhiwa kufuneka kuqhutywe ngokubanzi emva kokuba i-MJS i-jet grouting ephezulu yoxinzelelo igqityiwe kwaye iminyaka ifikelela kwixesha elichaziweyo kuyilo.
2 Ubungakanani bokuhlolwa komgangatho kunye nendawo
Inani leendawo zokuhlola yi-1% ukuya kwi-2% yenani lemingxuma yokwakha yokutshiza. Kwiiprojekthi ezinemingxuma engaphantsi kwama-20, ubuncinane inqaku elinye kufuneka lihlolwe, kwaye ezo zingaphumeleliyo kufuneka zitshizwe kwakhona. Iindawo zokuhlola kufuneka zicwangciswe kwezi ndawo zilandelayo: iindawo ezinemithwalo emikhulu, imigca yeziko lemfumba, kunye neendawo apho iimeko ezingaqhelekanga zenzeka khona ngexesha lokwakha.
3 Iindlela zokuhlola
Ukuhlolwa kweemfumba ze-jet grouting ikakhulu kukuhlolwa kwepropathi ngoomatshini. Ngokuqhelekileyo, isalathiso samandla oxinzelelo lomhlaba wesamente siyalinganiswa. Isampuli ifunyenwe ngokubhobhoza kunye nendlela yokugaya, kwaye yenziwe kwisiqwenga sovavanyo oluqhelekileyo. Emva kokuhlangabezana neemfuno, uvavanyo lwepropathi yangaphakathi kunye noomatshini lwenziwa ukujonga ukufana komhlaba wesamente kunye neempawu zawo zokwenza izinto.
