IIndlela yokwakha ye-CSMikwabizwa ngokuba yindlela yokuxuba nzulu yokusila. Ukudibanisa itekhnoloji yomatshini wokusila we-hydraulic groove & itekhnoloji yokuxuba nzulu, indlela entsha yolwakhiwo eludongeni ephantsi komhlaba iyenziwa; umgaqo ongundoqo kukusila ukubunjwa koqobo ngokusebenzisa iperi yamavili okusila ngehydraulic ekupheleni kombhobho wokubhola. Ukuxubha, ukuxuba, kunye nokuxuba i-cement slurry solidification liquid ngexesha elifanayo, emva kokuxutywa ngokupheleleyo kunye nokuxubana nomhlaba wesiseko owaphukileyo, udonga oluqhubekayo lwesamente olunamandla athile kunye nokusebenza kakuhle kokumisa amanzi kuyenziwa; Indlela yokwakha ye-CSM isetyenziselwa kakhulu ukuzinzisa umaleko womhlaba obuthathaka kunye nokhululekileyo, umhlaba oyisanti kunye nobumbano, umhlaba wegrabile, umhlaba wegrabile, ilitye eliqinileyo kunye nezinye izitrata; ifanelekile ukuqiniswa kwesiseko, isiseko somngxuma wokumisa umkhusane wamanzi, udonga lokumisa umngxuma wesiseko, umnyango wekhaka elingaphantsi kwendlela kunye nokuqiniswa komngxuma wokuphuma, ukugcina umhlaba + ukumisa Amanzi + udonga olusisigxina iindonga ezintathu kwelinye njalo njalo.
一、 Iimpawu zendlela yokwakha:
1. Ukulungelelanisa kuluhlu olubanzi
Iyakwazi ukwenza ulwakhiwo olunzulu lokuxuba kwi-hard stratum, kwaye inokusika i-stratum eqinile (ingqalutye kunye ne-stratum yegrabile, i-rock stratum eqinile), eyoyisa iziphene zenkqubo yokuxuba ye-multi-axis engakwazi ukwakhiwa kwi-hard stratum;
2. Ukuma kodonga kulungile
Ukuchaneka kodonga ngu ≤1/250. Isixhobo sinoluvo oluchanekileyo oluchanekileyo. Ngexesha lokwakha, ukuqina kwe-groove kunokujongwa ngamandla yikhompyutheni, kwaye inkqubo yokulungiswa kokuphambuka exhotywe ngezixhobo inokulungiswa ngexesha lokuqinisekisa ukuchaneka kodonga;
3. Umgangatho omhle wodonga
Isixa sokutofa kwe-sement slurry silawulwa yikhompyutheni, kwaye i-sement slurry kunye nomhlaba zixutywe ngokulinganayo, ukwenzela ukuba ukufana kodonga kunye nomgangatho ulungile, kwaye izinga lokusetyenziswa kwezinto eziphathekayo liphezulu. Xa kuthelekiswa nezinye iinkqubo zokuxuba, izinto eziphathekayo zinokugcinwa;
4. Ubunzulu bodonga bukhulu
Isixhobo sokuxuba intonga yesikhokelo esiphindwe kabini sinokugrumba kwaye sixube kubunzulu be-65 m; intambo yohlobo lwe-agitator enamavili amabini inokugrumba kwaye ixube kubunzulu be-80 m;
5. Ulwakhiwo luhambelana nokusingqongileyo
I-strata engaphazamisekiyo isetyenziswe ngokuthe ngqo njengezinto zokwakha, kwaye inani elipheleleyo lokuphanga kunye ne-slurry lincinci;
6. Ukuphazamiseka kolwakhiwo oluphantsi
Kukho phantse akukho vibration ngexesha lokwakha, kwaye i-in-situ yokuxuba iyamkelwa, enokuphazamiseka okuncinci kwisiseko sezakhiwo ezijikelezileyo kwaye inokwakhiwa kufuphi nezakhiwo.
二,, umgaqo wendlela yokwakha
Inkqubo yokwakhiwa kwendlela yokwakha ye-CSM ifana kakhulu neteknoloji yokuxuba enzulu, eyona nto ihlulwe ibe ziinxalenye ezimbini eziphambili: ukubhobhoza ukwenza i-groove kunye nokuphakamisa ukwenza udonga. Ngexesha lenkqubo yokugrumba kwiindawo zokubeka, amavili amabini okugaya ajikeleza ngokumalunga omnye komnye ukugaya ukubunjwa. Kwangaxeshanye, ukutyhutyha ukwehla kusetyenziswa ngentonga yesikhokelo ukusika nzulu ezantsi. Kule nkqubo, i-bentonite slurry okanye i-samente (okanye i-cement-bentonite) i-slurry ifakwe ngexesha elifanayo kwi-tank ngokusebenzisa inkqubo yepayipi ye-grouting. kubunzulu obufunekayo. Inkqubo yokuxhesha ngoku igqityiwe. Kwinkqubo yokunyusela eludongeni, amavili amabini okungqusha asajikeleza, kwaye amavili okungqusha aphakanyiswa kancinci ukuya phezulu ngentonga yesikhokelo. Ngethuba lenkqubo yokuphakamisa, i-samente (okanye i-cement-bentonite) i-slurry ifakwe kwi-tank ngokusebenzisa inkqubo yepayipi ye-grouting kwaye ixutywe kunye ne-muck kwi-tank. Ithekhinoloji yokwenza umkhombe we-CSM yahlukile kwi-emele yokuhlutha kwinkqubo yokwenza umkhombe, kwaye ayiyi kubumba udaka olubanjwe. Ekugqibeleni, i-drags iya kuxutywa kunye ne-sement slurry efakwe kwi-groove ukwenza udonga oluphantsi komhlaba lwe-diaphragm.
三、Itekhnoloji yokwakha kunye nenkqubo:
Indlela yokwakha ye-CSM inokwamkela ukwakhiwa kokuxuba ukuxuba kunye nokwakhiwa kokuxuba ukudibanisa. Ubude bephepha elinye yi-2.8m, ubude bomlenze buba yi-0.3m, kwaye ubude obusebenzayo bephepha elinye yi-2.5m.
Amanyathelo okwakha:
1. Indlela yolwakhiwo lwe-CSM yokubeka udonga nokumisa;
2. Gcoba umsele wesikhokelo (umsele wesikhokelo u-1.0-1.5 wamitha ububanzi kunye ne-0.8-1.0 yeemitha ubunzulu);
3.Isixhobo sisendaweni, kwaye intloko yokugaya ihambelana nendawo ye-groove
4.Ivili lokusila liyazika kwaye ligalele amanzi ukusika kunye nokusila umhlaba okwi-situ kubunzulu boyilo;
5.Ivili lokugaya liyaphakanyiswa kwaye i-slurry ye-grouting ishukunyiswa eludongeni ngokuhambelanayo;
6.Yiya kwindawo yokubeka elandelayo kwaye uphinde la manyathelo angasentla.
四, izixhobo zendlela yokwakha yeCSM:
Isixhobo sendlela yokwakha ye-CSM yesixhobo sokudibanisa ivili eliphindwe kabini, kukho iindidi ezimbini zodidi lwentonga yesikhokelo kunye nohlobo lwentambo, ubunzulu bokwakha bohlobo lwentonga yesikhokelo bunokufikelela kuma-65m, ubunzulu bokwakha bohlobo lwentambo bungafikelela kwi-80m, kwaye Ubukhulu bodonga yi-700 ~ 1200mm.
Okwangoku, izixhobo zombane ezisulungekileyo ezinamavili aphindwe kabini ziye zaphuhliswa e-China, kwaye i-hydraulic motor yemveli ithathelwa indawo yimoto yokuguqula amaza. Kwisiseko sokuqinisekisa ukusebenza kakuhle kolwakhiwo, iindleko zezixhobo kunye neendleko zokwakha ziyancipha ngakumbi.
五、Ubungakanani besicelo
1. Ukomelezwa kwesiseko;
2. Umkhusane wokumisa amanzi kumngxuma wesiseko;
3. Udonga olugcina umngxuma olusisiseko;
4. Ukomelezwa kwendlela yokungena ikhaka kunye nemingxuma yokuphuma;
5. Iimeko zokusebenza kunye neengqungquthela ezinkulu zokubunjwa kunye neekona ezininzi.
Kwiminyaka yakutshanje, indlela yokwakha ye-CSM isetyenziswe ngokubanzi kwaye isetyenziswe ngokubanzi e-China ngenxa yokusebenza kwayo okuphezulu kunye nefuthe elihle lokubumba udonga. Indlela yokwakha ye-CSM inokugcina kakhulu ikhonkrithi kunye nentsimbi, ukunciphisa iindleko zeprojekthi, ukuqinisekisa ukuphunyezwa kakuhle kweeprojekthi ezinkulu, kunye nokusombulula iingxaki ezinzima ze-geological. Phantsi kweemeko ezibuthathaka zemekobume yezixeko nezixeko, ingxaki enzulu yokulawula amanzi aphantsi komhlaba ejongene nokuphuhliswa kweendawo ezinzulu nezinkulu ezingaphantsi komhlaba ikhusela ngokufanelekileyo ukhuseleko lwezakhiwo ezimeleneyo, izakhiwo ezingaphantsi komhlaba, iitonela zikaloliwe ezingaphantsi komhlaba nemibhobho kamasipala, yaye ineengenelo eziphawulekayo kwezentlalo nezoqoqosho.
