中文I-MJS Yamandlela(Uhlelo lweMetro JET), elaziwa nangokuthi yindlela yokucindezela kwe-Jettling ephezulu kakhulu, ekuqaleni yathuthukiswa ukuxazulula izinkinga zokukhishwa kwe-slurry kanye nomthelela wezemvelo kwinqubo yokuvuselelwa kwe-jetrary evundlile. Njengamanje isetshenziselwa ukwelashwa okuyisisekelo, ukwelashwa kokuvuza nezinkinga zekhwalithi yePit Foundation Git Gcina ikhethini, kanye nokwelashwa kwekhasi le-water epaper odongeni lwangaphandle lwesakhiwo esingaphansi. Ngenxa yokusetshenziswa kwamapayipi ahlukile we-porous kanye namadivayisi we-slurry wokukhipha ama-slurry aphoqelelwe emgodini kanye nokucindezela kwengcindezi emhlabathini kuyalawulwa ngokulungiswa kwezokwelapha ngesikhathi sokwakha futhi kunciphise kakhulu umthelela emvelweni. Ukwehliswa kwengcindezi yenhlabathi kubuye kuqinise futhi kuqinisekiswe ububanzi benqwaba.
Ukulawulwa kwangaphambili
KusukelaI-MJS PILEUbuchwepheshe bokwakha buyinkimbinkimbi futhi bunzima kakhulu kunezinye izindlela zezinhlungu, kuyadingeka ukuthi balandele ngokuqinile izidingo zokwakha ngesikhathi senqubo yokwakha, yenza umsebenzi omuhle wenqubo yokusebenza ehambisanayo, futhi uthobele izinqubo zokusebenza ezihambisanayo ukuze uqinisekise ikhwalithi yokwakha.
Ngemuva kokuthi i-rig yokumba isendaweni, isikhundla senqwaba kufanele silawulwe kahle. Ngokuvamile, ukuphambuka kusuka endaweni yokuklama akufanele kudlule i-50mm, futhi ukuphambuka okuthe mpo akufanele kudlule u-1/24.
Ngaphambi kokwakhiwa okusemthethweni, ingcindezi kanye nokugeleza kwamanzi okucindezela okukhulu, iphampu yengcindezelo ephezulu ye-commepressor, kanye nejubane lokuphakamisa, ivolumu yemgodi, kanye nemibandela yokugcina yepayipi lemiloho ngesikhathi senkokhelo. Ngesikhathi sokwakhiwa okusemthethweni, ikhonsoli yokuphatha ephakathi nendawo ingasetshenziselwa ukulandela umkhondo okuzenzakalelayo nokulawula. Yenza amarekhodi anemininingwane amarekhodi ahlukahlukene okwakha esizeni, kufaka phakathi: Ukuthambekela kokudla, ukujula kokumba, ukuwa kwezithiyo, ukuwa, amapharamitha okusebenza ngesikhathi somjovo we-slurry, ukubuya kwe-slurry, njll., Bese ushiya idatha yokhiye. Ngasikhathi sinye, amarekhodi okwakha kufanele ahlelwe ngesikhathi, futhi kufanele kubikwe nezinkinga futhi kwaphathwa ngesikhathi.
Ukuze uqinisekise ukuthi akukho ukuqhekeka kwenqwaba lapho i-drill rod ihlukaniswa isikhathi eside ngenxa yezizathu ezithile, ubude bezinqwaba ezingemuva ngokuvamile bungaphansi kwe-100mm lapho kuqalwa khona umjovo ojwayelekile.
Gcina imishini yokwakha ngaphambi kokwakhiwa ukuze unciphise izinkinga zekhwalithi ezibangelwa ukwehluleka kwemishini ngesikhathi sokwakha. Yenza ukuqeqeshwa kwangaphambi kokwakhiwa kwabasebenza ngomshini ukuze ubajwayeze ngamaphoyinti wokusebenza kanye nokusebenza kwemishini. Ngesikhathi sokwakha, umuntu ozinikele unesibopho sokusebenza kwemishini.
Ukuhlolwa ngaphambi kokwakhiwa
Ngaphambi kokwakha, izinto zokwakha, imishini kanye nemishini, nenqubo yokufafaza kufanele ihlolwe, ikakhulukazi ezicini ezilandelayo:
1 Izitifiketi zekhwalithi kanye nemibiko yokuhlolwa koFakazi yezinto ezahlukahlukene eziluhlaza (kufaka phakathi usimende, njll.), Ukuxuba amanzi kufanele kuhlangane nemithetho ehambisanayo;
2 Ukuthi isilinganiso se-Slurry Mix silungele izimo zangempela zenhlabathi yephrojekthi;
3 Ukuthi imishini nemishini kuyinto ejwayelekile. Ngaphambi kokwakha, ama-MJS All-Round Hig-Ricker Rotary Equipment, Hole Dringing Rig, Iphampu ye-Slurry Pressure Mud, Isendlalelo Sokuxubana, kanye nenduku yokushayela (ikakhulukazi
4 Bheka ukuthi inqubo yokufafaza ilungele izimo zezwe lengqondo? Ngaphambi kokwakha, ukufafaza inqubo yokuhlola kufanele kwenziwe. Ukufafaza ukuhlolwa kufanele kwenziwe endaweni yokuqala yenqwaba. Inani lezimbobo zezinqwaba zokufafaza akufanele zibe ngaphansi kwezimbobo ezi-2. Uma kunesidingo, shintsha amapharamitha wokufafaza.
5 Ngaphambi kokwakha, izithiyo ezingaphansi komhlaba kufanele zihlolwe ngokufanayo ukuze ziqinisekise ukuthi ukumba nokufafaza kuhlangabezana nezidingo zokuklama.
6 Bheka ukunemba nokuzwela kwesikhundla senqwaba, ingcindezi yokugembula kanye nemitha yokugeleza ngaphambi kokwakhiwa.
Ukulawulwa Kwenqubo
Ngesikhathi sokwakha, okulandelayo kufanele kubhekwe:
1 Bheka i-verticatity yenduku yokumba, ijubane lokumba, ukujula kokumba, isivinini sokumba kanye nesivinini sokujikeleza nganoma yisiphi isikhathi ukubona ukuthi izidingo zombiko wenqwaba;
2 Hlola isilinganiso se-slurry mix ratio kanye nesilinganiso sezinto ezahlukahlukene ze-admixtures kanye nama-admixtures, bese uqopha ngeqiniso ingcindezi yomjovo, isivinini somjovo kanye nevolumu yomjovo ngesikhathi sokudonswa komjovo;
3 Ukuthi amarekhodi wokwakha aqediwe. Amarekhodi okwakha kufanele aqophe idatha yengcindezi kanye nokugeleza kanye yonke indawo yokuphakamisa noma ekushintsheni kwenhlabathi ushintsho, bese ushiya idatha yesithombe uma kunesidingo.
-Post-control
Ngemuva kokuqedwa kokwakha, inhlabathi eqinisiwe kufanele ihlolwe, kufaka phakathi: ubuqotho kanye nokufana kwenhlabathi ehlanganisiwe; ububanzi obusebenzayo benhlabathi ehlanganisiwe; amandla, ubukhulu obumaphakathi, kanye nesikhungo senqwaba yenhlabathi ehlanganisiwe; ukungakhululeki kwenhlabathi ehlanganisiwe, njll.
1 Isikhathi sokuhlola sekhwalithi nokuqukethwe
Njengoba ukuqina kwenhlabathi kasimende kudinga inani elithile lesikhathi, ngokuvamile izinsuku ezingama-28, izidingo ezithile kufanele zisuselwe kumadokhumenti e-design. Ngakho-ke, ukuhlolwa kwekhwalithi yeUkufafaza kwe-MJSUkwakhiwa kufanele kwenziwe ngokujwayelekile ngemuva kokugcwaliswa kwe-MJS High-High-Pressure Jet Grouting sekuqediwe futhi iminyaka ifinyelela ngesikhathi esibekiwe ekwakhiweni.
2 Inani lokuhlola okusezingeni eliphezulu nendawo
Inani lamaphoyinti wokuhlola yi-1% kuya ku-2% yenani lezimbobo zokufakelwa. Kumaphrojekthi anezimbobo ezingaphansi kwama-20, okungenani iphuzu elilodwa kufanele lihlolwe, futhi lezo zehluleka kufanele zifafazwe futhi. Amaphoyinti wokuhlola kufanele ahlelwe kulezi zindawo ezilandelayo: izindawo ezinemithwalo emikhulu, imigqa yesikhungo sezinqwaba, kanye nezindawo lapho kwenzeka khona izimo ezingesihle ngesikhathi sokwakha.
Izindlela ezi-3 zokuhlola
Ukuhlolwa kwama-Jet grouting piles kungukuhlolwa kwempahla okwenziwe ngomshini. Ngokuvamile, inkomba yamandla ecindezelayo yenhlabathi kasimende ilinganiswa. Isampula litholakala ngokumba kwendlela yokumba kanye ne-coring, futhi lenziwa ucezu olujwayelekile lokuhlola. Ngemuva kokuhlangabezana nezidingo, ukuhlolwa kwempahla yangaphakathi nokwenziwe ngomshini kwenziwa ukubheka ukufana kwenhlabathi kasimende kanye nezakhiwo zayo zemishini.
