Le khasiIndlela yokwakha ye-CSMIbizwa nangokuthi i-milling ejulile yokuxuba ukuxubana. Ukuhlanganisa ubuchwepheshe bomshini we-hydraulic groove milling nobuchwepheshe obujulile bokuxubana, indlela yokuqamba engaphansi komhlaba oqhubekayo oqhubekayo owenziwayo; Umgomo oyinhloko ukugaya ukwakheka kwangempela nge-pair of hydraulic milling amasondo emaphethelweni aphansi wepayipi elidonsa. Avuse, ukuxuba, kanye nokuxubana usimende oqinile we-slurry uketshezi ngasikhathi sinye, ngemuva kokushukumisa ngokugcwele futhi kuxubana nenhlabathi ephukile yasekuqaleni yesisekelo, kwakhiwa amandla aqhubekayo okusebenza kwamanzi nokusebenza okuhle kwamanzi; Indlela yokwakha ye-CSM isetshenziselwa kakhulu ukuzinza ubuthakathaka futhi i-sandy ungqimba lomhlabathi, inhlabathi enesihlabathi futhi ebumbana, inhlabathi yamatshe, inhlabathi enamatshe, idwala eliqinile le-strata; Ilungele ukuqiniswa kwesisekelo, i-Foundation Pit Water-Misa i-Cetain, i-Foundation Pit Git Retation Wall, Subway Shield Entraction kanye nokuqedwa komgodi wokuphuma, ukugcina amanzi + okugcina izindonga ezintathu.
一, izici zendlela yokwakha:
1. Hlela ukujwayela i-strata ebanzi
Kungafeza ukwakhiwa okujulile kokuxubana e-hard stratum, futhi kunganciphisa stratum eqinile (i-pebble ne-gravel stratum, stratum eqinile ye-rock stratum), enqoba ukushiyeka kohlelo lwendabuko oluningi olungeke lwakhiwe endaweni enzima;
2. I-verticality yodonga ilungile
Ukunemba kodonga kungu-≤1 / 250. Imishini inezinzwa ezingenzeka nge-verticality sensor ephezulu. Ngesikhathi sokwakha, i-verticality ye-groove ingabhekelwa ngamandla yikhompyutha, futhi uhlelo lokulungiswa kokuphambuka luhlonyelwe imishini lungalungiswa ngesikhathi ukuze kuqinisekiswe ukunemba kodonga;
3. Ikhwalithi enhle yodonga
Inani lomjovo we-Cement Slurry lilawulwa yi-computer, futhi i-slurry kasimende nenhlabathi ixubene kahle, ukuze ukufana kodonga kanye nekhwalithi yokusetshenziswa okuphezulu kuphezulu. Uma kuqhathaniswa nezinye izinqubo zokuxuba, izinto zokwakha zingasindiswa;
4. Ukujula kodonga kukhulu
Imishini yokuhlobisa imishini yokuxuba amasondo amabili ingahle yembule futhi ihlanganise ukujula kuka-65 m; Uhlobo lwentambo enamasondo amabili lungamba futhi luxube ukujula kwama-80 m;
5. Ukwakhiwa kungomusa okwemvelo
I-strata engaphazanyiswa isetshenziswa ngokuqondile njengezinto zokwakha, nenani eliphelele lempango kanye ne-slurry lincane;
6. Ukuphazamiseka kokwakhiwa okuphansi
Cishe akukho okudlidliza ngesikhathi sokwakha, nokuxutshwa kwe-In-Situ kuthathwe, okunokuphazamiseka okuncane ekusekelweni kwezakhiwo ezizungezile futhi kwakhiwe eduze kwezakhiwo.
二 ,, umgomo wendlela yokwakha
Inqubo yokwakha yendlela yokwakha ye-CSM ifana kakhulu nobuchwepheshe obujulile bokuxubana, okuhlukaniswe kakhulu izingxenye ezimbili eziphambili: ukumba phansi ukwakha i-groove nokukhuthaza ukwakha udonga. Ngesikhathi senqubo yokugaya yaba yi-slots, amasondo amabili okugaya ajikeleze isihlobo komunye nomunye ukugaya ukwakheka. Ngasikhathi sinye, i-topward town isetshenziswa ngenduku yokuqondisa ukusika phansi. Kule nqubo, i-bentonite slurry noma usimende (noma usimende-bentonite) i-slurry ngasikhathi sinye ithambiwe ethangini ngohlelo lwe-grouting pipeline system. ekujuleni okudingekayo. Inqubo yokukhonkotha isiqediwe manje. Enqubweni yokuphakamisa odongeni, amasondo amabili okugaya asajikeleza, futhi amasondo okugaya aphakanyiswa kancane phezulu ngenduku yenkomba. Ngesikhathi sokuphakamisa, usimende (noma usimende-bentonite) i-slurry ifakwe ethangini ngokusebenzisa uhlelo lwe-prepine futhi luxutshwe ne-muck ethangini. I-CSM TRROUSHWARY CHARCH IQINISO LUHLE KWI-Darb Blueket kwinqubo yokwakha umkhondo, futhi ngeke yakha i-muck ebanjiwe. Ekugcineni, ama-Dregs azohlanganiswa ne-slurry kasimende enjongweni e-groove ukwakha udonga olungaphansi komhlaba.
三, ubuchwepheshe bokwakha kanye nenqubo:
Indlela yokwakha ye-CSM ingashintsha ukwakhiwa kokwakhiwa kwe-jump-kushayele ukuxuba nokwakhiwa okuphansi kokushaya. Ubude beshidi elilodwa ngu-2.8m, ubude be-LAP ngokuvamile bungu-0.3m, kanye nobude obusebenzayo beshidi elilodwa ngu-2,5m.
Izinyathelo zokwakha:
1. Indlela yokwakha ye-CSM yokwakha udonga ukuma nokubeka;
2. Yembule umsele wesiqondisi (umsele wesiqondisi yi-1.0-1,5 meters ububanzi kanye no-0.8-1.0 amamitha ajulile);
3.Imishini isendaweni, futhi ikhanda lokugaya liqondaniswe nesikhundla se-groove
I-Wheel yokugaya icwila futhi ifaka amanzi ukusika nokugaya inhlabathi in-situ ekujuleni komklamo;
Isondo lokugaya liphakanyiswa futhi ama-slurry acwebezelayo ashukunyiswa odongeni oluvumelanayo;
6.Move esimweni esilandelayo se-slot bese uphinda izinyathelo ezingenhla.
四, Imishini yokwakha ye-CSM:
I-CSM Yokwakha Indlela Yemishini Yokuxubha I-Rig yokuxuba ama-Wheel-wheel-wheel-wheel-wheel, izinhlobo zohlobo lomhlahlandlela nohlobo lwentambo, ukujula okuphezulu kokwakhiwa kohlobo lwentambo kungafinyelela kuma-80m, futhi ubukhulu bodonga bungama-700 ~ 1200mm.
Njengamanje, imishini evutha amasondo emsulwa evutha kabili eChina, futhi imoto yendabuko ye-hydraulic ithathelwa indawo yemoto yokuguqulwa imvamisa. Esisekelweni sokuqinisekisa ukusebenza kwezokwakha, izindleko zemishini nezindleko zokwakha ziya ngokuya zincishiswa.
五, ubukhulu besicelo
1. Isisekelo sokuqiniswa;
2. Shisa ikhethini lamanzi lomgodi wesisekelo;
3. Isisekelo Phind Git Gcina udonga;
I-4. Ukuqiniswa kokungenisa izivikelo ezivikelekile nezimbobo zokuphuma;
I-5. Izimo zokusebenza ezinamazinga amakhulu okwakha kanye namakhona amaningi.
Eminyakeni yamuva, indlela yokwakha ye-CSM ibilokhu isetshenziswa kabanzi eChina ngenxa yokusebenza kwayo okuphezulu kokwakha kanye nomphumela omuhle wokwakha udonga. Indlela yokwakha ye-CSM ingasindisa kakhulu ukhonkolo nensimbi, yehlise izindleko zephrojekthi, iqinisekise ukusetshenziswa kahle kwamaphrojekthi amakhulu, futhi ixazulule izinkinga eziyinkimbinkimbi zezwe. Ngaphansi kwezimo ezibucayi zemvelo zamadolobha namadolobha, inkinga yokulawula okujulile kwamanzi abhekene nentuthuko yezikhala ezijulile ezingaphansi komhlaba zivikela ngempumelelo ukuphepha kwezakhiwo eziseduzane, izakhiwo ezingaphansi komhlaba, futhi zinezinzuzo ezimangazayo zenhlalo nezomnotho.
