Indlela yokwakha eyinhloko yodonga lwe-diaphragm: Indlela yokwakha ye-SMW, indlela yokwakha ye-TRD, indlela yokwakha ye-CSM

I-SMW(Soil Mixing Wall) udonga oluqhubekayo lwethulwa e-Japan ngo-1976. Indlela yokwakha ye-SMW ukubhoboza ukujula okuthile ensimini nge-multi-axis drilling mixer. Ngesikhathi esifanayo, i-ejenti yokuqinisa usimende ifafazwa endaweni yokubhoboza futhi ihlanganiswe nenhlabathi yesisekelo ngokuphindaphindiwe. Ukwakhiwa okugqagqeneyo kanye ne-lapped kwamukelwa phakathi kweyunithi ngayinye yokwakha. Yakha udonga olungaphansi komhlaba oluqhubekayo futhi oluphelele, olungahlanganisi olunamandla athile nokuqina.

Indlela yokwakha i-TRD: Ukusika umsele Ukuhlanganisa kabusha indlela yodonga olujulile (Ukusika umsele ukuhlanganisa kabusha indlela yodonga olujulile) Umshini usebenzisa ibhokisi lokusika elinekhanda lokusika iketango kanye nepayipi lokusika elifakwe emhlabathini ukuze kunqunywe ukujula nokusika okuphambene. , futhi yenza umjikelezo wokuya phezulu naphansi ukuze unyakaze ngokugcwele, kuyilapho ujova i-coagulant usimende. Ngemva kokuphulukisa, udonga oluqhubekayo lukasimende-inhlabathi luyakhiwa. Uma into eyinhloko njengensimbi emise okwe-H ifakwe kule nqubo, udonga oluqhubekayo lungaba isitobhi esisha samanzi kanye nobuchwepheshe bokwakhiwa kwesakhiwo sokwesekwa kwe-anti-seepage obusetshenziswa odongeni olugcina inhlabathi kanye nodonga oluvimbela ukugeleza kwamanzi noma odongeni oluthwala umthwalo ngaphakathi. iphrojekthi yokumba.

Indlela ye-CSM: (I-Cutter Soil Mixing) Ubuchwepheshe bokuxuba obujulile bokugaywa: Kuwudonga olusha olungaphansi komhlaba lwe-diaphragm noma okokusebenza kodonga lwe-seepage okuhlanganisa umshini wokuqala wokugaya we-hydraulic groove womshini nobuchwepheshe bokuxuba obujulile, obuhlanganiswe nezici zobuchwepheshe zemishini yokugaya i-hydraulic groove. kanye nensimu yokusetshenziswa kobuchwepheshe bokuxuba okujulile, okokusebenza kusetshenziselwa izimo ze-geological eziyinkimbinkimbi, kodwa futhi ngokuxuba inhlabathi ye-in-situ kanye nosimende. udaka endaweni yokwakha. Ukwakhiwa kodonga oluvimbela ukubola, udonga olubambayo, ukuqinisa isisekelo namanye amaphrojekthi.
