IIndlela yokwakha ye-CSMibizwa nangokuthi indlela yokuxuba ejulile yokugaya.Ukuhlanganisa ubuchwepheshe bomshini wokugaya i-hydraulic groove & nobuchwepheshe bokuxuba okujulile, indlela entsha yokwakhiwa kwezindonga engaphansi komhlaba iyenziwa;umgomo oyinhloko uwukugaya ukwakheka kwasekuqaleni ngokusebenzisa ipheya lamasondo okugaya asebenza ngogesi ekugcineni okuphansi kwepayipi lokubhoboza.Ukugqugquzela, ukuxuba, nokuxuba uketshezi oluqinile lukasimende oluqinile ngesikhathi esifanayo, ngemva kokuhlanganisa ngokugcwele nokuxubana nomhlabathi wesisekelo ophukile, udonga oluqhubekayo lukasimende olunamandla athile kanye nokusebenza kahle kokumisa amanzi kuyakhiwa;Indlela yokwakha ye-CSM isetshenziswa ngokuyinhloko ukuze kuqiniswe ungqimba lomhlabathi obuthakathaka futhi oxekethile, inhlabathi enesihlabathi nebumbene, inhlabathi ewubhuqu, inhlabathi ewubhuqu, idwala elinesimo sezulu esiqinile nezinye izigaba;kufanelekile ukuqinisa isisekelo, isisekelo somgodi wokumisa ikhethini lokumisa amanzi, udonga olugcina umgodi wesisekelo, umnyango wesihlangu esingaphansi komhlaba kanye nokuqiniswa komgodi wokuphuma, ukugcina inhlabathi + ukumisa Amanzi + udonga oluhlala njalo izindonga ezintathu kwelinye njalonjalo.
一、 Izici zendlela yokwakha:
1. Zivumelanise nezigaba ezibanzi
Ingakwazi ukwenza ukwakhiwa kokuxuba okujulile ku-stratum eqinile, futhi ingasika i-stratum eqinile (itshe letshe kanye ne-gravel stratum, i-rock stratum enamandla), enqoba ukushiyeka kwesistimu yokuhlanganisa ama-multi-axis engakwazi ukwakhiwa nge-hard stratum;
2. Ukuma kodonga kuhle
Ukunemba kodonga ngu-≤1/250.Izinto zokusebenza zinenzwa yokuma eqondile ephezulu.Ngesikhathi sokwakha, ukuphakama kwe-groove kungabhekwa ngamandla yikhompyutha, futhi uhlelo lokulungiswa kokuphambuka olufakwe imishini lungalungiswa ngesikhathi ukuze kuqinisekiswe ukunemba kodonga;
3. Ikhwalithi enhle yodonga
Inani lomjovo lodaka lukasimende lilawulwa ngekhompuyutha, futhi udaka lukasimende nomhlabathi kuxutshwe ngokulinganayo, ukuze ukufana kodonga kanye nekhwalithi kube kuhle, futhi izinga lokusebenzisa impahla liphezulu.Uma kuqhathaniswa nezinye izinqubo zokuxuba, izinto zokwakha zingagcinwa;
4. Ukujula kodonga kukhulu
I-guide rod yohlobo lwemishini yokuhlanganisa enamasondo amabili ingamba futhi ixube ekujuleni okungamamitha angama-65;i-agitator yohlobo lwezintambo enamasondo amabili ingamba futhi ixube ekujuleni okungamamitha angama-80;
5. Ukwakhiwa kuhambisana nemvelo
I-strata engaphazamiseki isetshenziswa ngokuqondile njengezinto zokwakha, futhi inani eliphelele lokuchithwa kanye ne-slurry lincane;
6. Ukuphazamiseka kokwakhiwa okuphansi
Cishe akukho ukudlidliza ngesikhathi sesiteji sokwakha, futhi ukuxuba kwe-in-situ kuyamukelwa, okunokuphazamiseka okuncane esisekelweni sezakhiwo ezizungezile futhi kungakhiwa eduze kwezakhiwo.
二,, isimiso sendlela yokwakha
Inqubo yokwakha yendlela yokwakha ye-CSM ifana kakhulu nobuchwepheshe bokuxuba okujulile, okuhlukaniswa ngokuyinhloko izingxenye ezimbili eziyinhloko: ukubhoboza phansi ukuze wenze i-groove nokuphakamisa ukuze wenze udonga.Phakathi nenqubo yokumba kube izikhala, amasondo amabili okugaya ayazungeza ahlobene ukuze agaye ukwakheka.Ngesikhathi esifanayo, i-propulsion eya phansi isetshenziswa ngenduku yomhlahlandlela ukusika ngokujulile phansi.Kule nqubo, i-bentonite slurry noma usimende (noma usimende-bentonite) i-slurry ifakwa ngesikhathi esisodwa ethangini ngesistimu yepayipi ye-grouting.ekujuleni okudingekayo.Inqubo yokubhoboza isiqediwe.Ngesikhathi sokukhuphukela odongeni, amasondo amabili okugaya asazungeza, futhi amasondo okugaya aphakanyiselwa phezulu kancane kancane ngenduku yokuqondisa.Ngesikhathi senqubo yokuphakamisa, usimende (noma usimende-bentonite) udaka lujovwa ethangini ngohlelo lwephayiphi le-grouting bese luxutshwa nodaka ethangini.Ubuchwepheshe bokwenza umphongolo we-CSM buhlukile kunebhakede lokubamba enqubweni yokwenza umkhombe, futhi ngeke bakhe udaka olubanjiwe.Ekugcineni, amahleze azohlanganiswa nodaka lukasimende olujovwe emseleni ukuze kwakheke udonga olungaphansi komhlaba lwe-diaphragm.
三、Ubuchwepheshe bokwakha kanye nenqubo:
Indlela yokwakha ye-CSM ingasebenzisa ukwakhiwa kokuxubana kwe-jump-beating kanye nokwakhiwa kokuxuba okushaya phansi.Ubude beshidi elilodwa buyi-2.8m, ubude bethanga ngokuvamile bungu-0.3m, kanti ubude obusebenzayo beshidi elilodwa bungu-2.5m.
Izinyathelo zokwakha:
1. Indlela yokwakhiwa kwe-CSM yokubeka udonga nokubekwa ngaphandle;
2. Gcoba umsele wokuqondisa (umsele wokuqondisa ungamamitha angu-1.0-1.5 ububanzi namamitha angu-0.8-1.0 ukushona);
3.Imishini isendaweni, futhi inhloko yokugaya ihambisana nokuma kwe-groove
4.Isondo lokugaya liyazika futhi lijova amanzi ukuze lisike futhi ligaye inhlabathi ye-in-situ ekujuleni komklamo;
5.Isondo lokugaya liyaphakanyiswa futhi i-grouting slurry inyakaziswa odongeni ngokuhambisana;
6.Yiya endaweni elandelayo bese uphinda izinyathelo ezingenhla.
四 、Imishini yendlela yokwakha ye-CSM:
Imishini yokwakha ye-CSM yendlela yokwakha exuba insimbi yokumba enamasondo amabili, kunezinhlobo ezimbili zohlobo lwenduku yomhlahlandlela kanye nohlobo lwentambo, ukujula okuphezulu kokwakhiwa kohlobo lwenduku yomhlahlandlela kungafinyelela ku-65m, ukujula okuphezulu kokwakhiwa kohlobo lwentambo kungafinyelela ku-80m, futhi Ubukhulu bodonga buyi-700 ~ 1200mm.
Njengamanje, imishini kagesi ehlanzekile edonsa ngamasondo aphindwe kabili yakhiwe e-China, futhi i-hydraulic motor yendabuko ithathelwa indawo yimoto yokuguqula imvamisa.Ngokwesisekelo sokuqinisekisa ukusebenza kahle kokwakhiwa, izindleko zemishini kanye nezindleko zokwakha ziphinde zehliswe.
五、Ububanzi besicelo
1. Ukuqinisa isisekelo;
2. Ikhethini lokumisa amanzi lomgodi wesisekelo;
3. Isisekelo sodonga olugcina umgodi;
4. Ukuqiniswa kokungena kwesihlangu esingaphansi komhlaba kanye nezimbobo zokuphuma;
5. Izimo zokusebenza ezinezingxabano ezinkulu zokubunjwa kanye namakhona amaningi.
Eminyakeni yamuva nje, indlela yokwakha ye-CSM iye yasetshenziswa kabanzi futhi yanda kakhulu e-China ngenxa yekhono layo eliphezulu lokwakha kanye nomphumela omuhle wokwakha udonga.Indlela yokwakha ye-CSM ingasindisa kakhulu ukhonkolo nensimbi, inciphise izindleko zephrojekthi, iqinisekise ukuqaliswa kahle kwamaphrojekthi amakhulu, futhi ixazulule izinkinga eziyinkimbinkimbi ze-geological.Ngaphansi kwezimo ezibucayi zemvelo zamadolobha namadolobhakazi, inkinga yokulawula amanzi angaphansi komhlaba ajulile ebhekene nokuthuthukiswa kwezindawo ezijulile nezinkulu ezingaphansi komhlaba ivikela ngokuphumelelayo ukuphepha kwezakhiwo eziseduze, izakhiwo ezingaphansi komhlaba, imigudu ehamba ngaphansi komhlaba namapayipi kamasipala, futhi inezinzuzo eziphawulekayo kwezenhlalo nezomnotho.
