中文Indlela ye-MJS(I-Metro Jet System), eyaziwa nangokuthi indlela yokundiza enengcindezi ephezulu ejikeleza yonke indawo, yasungulwa ekuqaleni ukuze kuxazululwe izinkinga zokuphuma kodaka kanye nomthelela wemvelo ohlelweni lokwakhiwa kwejethi ejikelezayo evundlile. Njengamanje isetshenziselwa kakhulu ukwelashwa kwesisekelo, ukwelashwa kokuvuza kanye nezinkinga zekhwalithi zomgodi wesisekelo ogcina ikhethini lokumisa amanzi, kanye nokwelapha ukugeleza kwamanzi odongeni lwangaphandle lwesakhiwo esingaphansi. Ngenxa yokusetshenziswa kwamapayipi anezimbotshana ezingavamile kanye nemishini yokumunca udaka oluphoqelekile ekupheleni, ukuphoqeka kokukhishwa kwe-slurry emgodini kanye nokuqapha kwengcindezi yomhlabathi kuyabonakala, futhi ukucindezela komhlaba kulawulwa ngokulungisa ivolumu yokukhipha udaka oluphoqelekile, ukuze kukhishwe udaka olujulile futhi ukucindezela komhlaba kulawulwa ngokufanele, futhi ukucindezela komhlaba kuzinzile, okunciphisa amathuba okuguqulwa kwendawo ngesikhathi sokwakhiwa futhi kunciphisa kakhulu umthelela emvelweni. Ukwehliswa kokucindezela komhlaba nakho kuqinisekisa ngokuqhubekayo ububanzi benqwaba.
Ukulawula kwangaphambili
Kusukela iIfayela le-MJSubuchwepheshe bokwakha bunzima kakhulu futhi bunzima kakhulu kunezinye izindlela zokugaya, kuyadingeka ukuthi ulandele ngokuqinile izidingo zokuklama ngesikhathi senqubo yokwakha, wenze umsebenzi omuhle wokwaziswa okuhambisanayo kwezobuchwepheshe nokuphepha, futhi uhambisane nezinqubo zokusebenza ezihambisanayo ukuze uqinisekise ikhwalithi yokwakha. .
Ngemuva kokuthi i-rig yokumba isendaweni, indawo yenqwaba kufanele ilawulwe kahle. Ngokuvamile, ukuchezuka endaweni yokuklama akufanele kudlule u-50mm, futhi ukuchezuka okuqondile akufanele kudlule i-1/200.
Ngaphambi kokwakhiwa okusemthethweni, ingcindezi nokugeleza kwamanzi anomfutho ophezulu, iphampu ye-high-pressure grouting kanye ne-compressor yomoya, kanye nesivinini sokuphakamisa, ivolumu ye-grouting, nezimo zokugcina zembobo yepayipi ye-grouting ngesikhathi senqubo yomjovo kunqunywa ngokusebenzisa ukuhlolwa. izinqwaba. Ngesikhathi sokwakhiwa okusemthethweni, ikhonsoli yokuphatha emaphakathi ingasetshenziselwa ukulandelela nokulawula okuzenzakalelayo. Yenza amarekhodi anemininingwane yamarekhodi okwakha ahlukahlukene esizeni, okuhlanganisa: ukuthambekela kokumba, ukujula kokumba, izithiyo zokumba, ukuwa, amapharamitha okusebenza ngesikhathi sokujova ngodaka, ukubuya kodaka, njll., nokushiya idatha yesithombe esibalulekile. Ngesikhathi esifanayo, amarekhodi okwakha kufanele ahlungwe ngesikhathi, futhi izinkinga kufanele zibikwe futhi zisingathwe ngesikhathi.
Ukuze kuqinisekiswe ukuthi akukho ukuphuka kwenqwaba lapho i-drill rod ihlakazwa noma umsebenzi uphazamiseka isikhathi eside ngenxa yezizathu ezithile, ubude bokugqagqana kwezinqwaba ezingaphezulu nezingaphansi ngokuvamile abukho ngaphansi kuka-100mm lapho umjovo ojwayelekile uqalwa kabusha. .
Gcina imishini yokwakha ngaphambi kokwakhiwa ukuze unciphise izinkinga zekhwalithi ezibangelwa ukwehluleka kwemishini ngesikhathi sokwakha. Yenza ukuqeqeshwa kwangaphambi kokwakhiwa kwabaqhubi bemishini ukuze bajwayelane nokusebenza kanye nezindawo zokusebenza zemishini. Ngesikhathi sokwakha, umuntu ozinikele unesibopho sokusebenza kwemishini.
Ukuhlolwa ngaphambi kokwakhiwa
Ngaphambi kokwakhiwa, izinto zokusetshenziswa, imishini nemishini, kanye nenqubo yokufafaza kufanele ihlolwe, ikakhulukazi kulezi zici ezilandelayo:
1 Izitifiketi zekhwalithi kanye nemibiko yokuhlolwa kofakazi yezinto ezisetshenziswayo ezihlukahlukene (okuhlanganisa usimende, njll.), ukuxuba amanzi kufanele kuhlangabezane nemithethonqubo ehambisanayo;
2 Ukuthi isilinganiso sengxube ye-slurry sizifanele izimo zenhlabathi zangempela zephrojekthi;
3 Ukuthi imishini nezinto zokusebenza zijwayelekile yini. Ngaphambi kokwakhiwa, i-MJS yonke imishini yejethi ejikelezayo enengcindezi ephezulu, imbobo yokumba imbobo, iphampu yodaka enomfutho ophezulu, isizinda sokuxuba udaka, iphampu yamanzi, njll. kufanele ihlolwe futhi isebenze, kanye ne-drill rod (ikakhulukazi izinduku zokubhola eziningi) , i-drill bit kanye nedivaysi yokuqondisa kufanele ingavinjwa;
4 Hlola ukuthi inqubo yokufafaza ifanele yini izimo zejoloji. Ngaphambi kokwakhiwa, ukuhlolwa kwenqubo yokufafaza kufanele kwenziwe. Ukufafaza kokuhlola kufanele kwenziwe endaweni yokuqala yenqwaba. Inombolo yezimbobo zenqwaba yokufafaza akufanele ibe ngaphansi kwezimbobo ezi-2. Uma kunesidingo, lungisa imingcele yenqubo yokufafaza.
5 Ngaphambi kokwakhiwa, izithiyo ezingaphansi komhlaba kufanele zihlolwe ngokulinganayo ukuze kuqinisekiswe ukuthi ukubhoboza nokufafaza kuhlangabezana nezidingo zokuklama.
6 Hlola ukunemba nokuzwela kwendawo yenqwaba, igeji yokucindezela kanye ne-flow meter ngaphambi kokwakhiwa.
Ukulawula okungaphakathi kwenqubo
Phakathi nenqubo yokwakha, okulandelayo kufanele kunakwe:
1 Hlola ukuma kwenduku yokubhoboza, isivinini sokumba, ukujula kokumba, isivinini sokumba kanye nesivinini sokuzungeza nganoma yisiphi isikhathi ukuze ubone ukuthi kuyahambisana yini nezidingo zombiko wokuhlolwa kwenqwaba;
2 Hlola isilinganiso sengxube kasimende nesilinganiso sezinto ezihlukahlukene nezixube, futhi urekhode ngokweqiniso ingcindezi yomjovo, isivinini somjovo kanye nevolumu yomjovo ngesikhathi somjovo;
3 Ukuthi amarekhodi okwakha aphelele yini. Amarekhodi okwakha kufanele aqophe idatha yokucindezela nokugeleza kanye njalo nge-1m yokuphakanyiswa noma lapho kuhlangana khona ungqimba lomhlabathi kushintsha, futhi ashiye idatha yesithombe uma kunesidingo.
Ngemuva kokulawula
Ngemva kokuqedwa kokwakhiwa, inhlabathi eqinisiwe kufanele ihlolwe, kuhlanganise: ubuqotho nokufana kwenhlabathi ehlanganisiwe; ububanzi obusebenzayo bomhlabathi ohlanganisiwe; amandla, ububanzi obuyisilinganiso, kanye nendawo ephakathi kwenqwaba yenhlabathi ehlanganisiwe; ukungakwazi ukucwiliswa kwenhlabathi ehlanganisiwe, njll.
1 Isikhathi sokuhlolwa kwekhwalithi nokuqukethwe
Njengoba ukuqinisa umhlabathi kasimende kudinga isikhathi esithile, ngokuvamile esingaphezu kwezinsuku ezingama-28, izidingo ezithile kufanele zisekelwe emibhalweni yokuklama. Ngakho-ke, ukuhlolwa kwekhwalithi yeUkufafaza kwe-MJSukwakhiwa kufanele ngokuvamile kwenziwe ngemva kokuba i-MJS high-pressure jet grouting isiqediwe futhi iminyaka ifinyelela isikhathi esinqunyiwe ekwakhiweni.
2 Inani lokuhlolwa kwekhwalithi nendawo
Inombolo yezindawo zokuhlola i-1% kuya ku-2% yenani lemigodi yokufafaza yokwakha. Kumaphrojekthi anezimbobo ezingaphansi kuka-20, okungenani iphuzu elilodwa kufanele lihlolwe, futhi lawo angaphumeleli kufanele afuthwe futhi. Izindawo zokuhlola kufanele zihlelwe kulezi zindawo ezilandelayo: izindawo ezinemithwalo emikhulu, imigqa yesikhungo senqwaba, nezindawo lapho izimo ezingavamile zenzeka khona ngesikhathi sokwakha.
3 Izindlela zokuhlola
Ukuhlolwa kwezinqwaba ze-jet grouting ikakhulukazi ukuhlolwa kwempahla ngomshini. Ngokuvamile, inkomba yamandla acindezelayo enhlabathini kasimende iyalinganiswa. Isampula itholakala ngokubhoboza kanye nendlela yokufaka amakhora, futhi yenziwa ucezu olujwayelekile lokuhlola. Ngemuva kokuhlangabezana nezidingo, ukuhlolwa kwempahla yangaphakathi nemishini kwenziwa ukuze kuhlolwe ukufana kwenhlabathi kasimende kanye nezakhiwo zayo zemishini.
