Uyini cementation ka nenhlabathi futhi lapho kudingeka khona

Inhlabathi grouting isetshenziswa kakhulu ukungadluliseli inhlabathi nokuzinza ukwakhiwa okwalandela zezakhiwo noma ezinye engadini. Le nqubo efanele ezindaweni ezithandwa ukuguguleka komhlabathi kanye ukuguguleka kwenhlabathi. Inqubo ngokuvamile kwenziwa ezindaweni exhaphozini eduze namanzi noma ngomuthi itafula ezindaweni amanzi okusezingeni eliphezulu.

Phakathi kwazo zonke izindlela ezisetshenziswa ukuqinisa inhlabathi grouting iyona ndlela ejwayeleke kakhulu. Kuyinto phakathi ezinye izindlela ezingabizi kakhulu, kodwa akukho kancane kunokuphakela efanayo, futhi kuyasiza ukwandisa umthamo ethwele zenhlabathi, esiza ukunweba ukuphila service kwezakhiwo.

sphere kwesicelo

Grouting livame ukusetshenziswa embonini yezokwakha ngoba:

1. Ukwakhela izakhiwo emhlabathini engazinzile.
2. Works of ukulungisa isebenza izitshalo indle.
3. oluqinisayo okwesikhashana noma unomphela ngemisebenzi ngomshoshaphansi.
4. Ukuqinisa of izisekelo ekhona.
5. Ukuqiniswa inhlabathi Karst.

Okhulisa kwenziwa cementation zemvelo indlela igcwalisa ngalo ingaphakathi enhlabathini, kanjalo ngcono ukuqina yayo. Lokhu Indlela futhi olufanele lapho unscheduled Kutholwe phansi izindawo mobile kakhulu ezakhiweni.

design

Geology for ukwakhiwa linendima ebalulekile. Ekuklanyweni isakhiwo ikhokhelwa eziningi ukunakekela izinga inhlabathi, indawo, amanzi angaphansi komhlaba nezinye izinto ezingaba kunciphisa ukuphila ezisebenza yokwakha. Ekuklanyweni grouting kubalulekile ukunquma izinto ezilandelayo:

• Zone yasibamba futhi eziveza amandla kwenhlabathi.
• grouting indlela. It ziyahlukahluka kusuka ukhetho isabelomali nge imishini ehlukile futhi ujova isixazululo esebenzisa injector ukuba ukusetshenziswa imishini ebizayo.
• Ukwakheka nenani usimende nosimende. It kuncike yi oyifunayo, kwabantu kokuqala zenhlabathi, usimende kanye plasticizers eyengeziwe kanye accelerators.
• Ukulawula izinga umsebenzi owawenziwa. Ukuze ukuhlolwa yayo ukusebenza ziqhutshwa Izakhiwo kanye mechanical inhlabathi emva grouting.

La maphuzu kuzosiza sifeze inqubo ngokuyimpumelelo futhi kancane ebizayo.

Jet grouting Soil

Kuyinto indlela yokuqinisa ngokujova grout ngokusebenzisa injectors ku imithombo yamba. Ngenxa yalokho we yinqwaba umsebenzi wokwakha usimende kwakhiwa, okuyinto uma oyifunayo kungenzeka eminye lwaqiniswa metal rod.

Phakathi nomsebenzi eceleni fed ikhambi amanzi usimende, umoya namanzi, okuyinto uma udala usimende solidification uzimele. Kulokhu, qapha Rig ubonisa ulwazi olugcwele mayelana nenqubo.

Izinzuzo jet grouting

Izinzuzo le ndlela ibandakanya:

• ukusebenza - ukukhishwa okusheshayo imisebenzi;
• kungenzeka umsebenzi kwezinye izindawo inhlabathi kokubili ngaphansi nangaphezulu ezingeni komhlaba;
• izinga okusezingeni yenqubo;
• ukungabi khona umsindo bese vibration, okuvumela izenzo ezithile ngisho endaweni yokuhlala ezinabantu abaningi;
• uma usebenza ngaphakathi esakhiweni zingafundwa usebenzisa yokumba encane.

Lezi izinzuzo ziyabhekelelwa lapho ekhetha indlela yokuqinisa inhlabathi engazinzile.

ekuqiniseni izisekelo

cementation amasu ngokuvamile sisetshenziswa ukuthuthukisa ngezizathu ekhona. Kulokhu, isisekelo yedwa uthola ukwesekwa eyengeziwe ukuvimbela ukubukeka imifantu izindonga wokugoqa ephelele izakhiwo.

I Rig has a ukuhamba okusezingeni eliphezulu, okukuvumela ukuba ngiyibeke eduze isakhiwo. usayizi amancane mobile imishini insika ukuvumela ukusebenza ngaphandle umsindo ngokweqile futhi vibration.

Isisekelo ematheni is iyakhula usebenzisa izinhlobo ezinjalo kasimende:

• Portland;
• slag;
• alumina;
• sulfate;
• backfill;
• shlakoshchelochnyh.

Lezi amamaki aqukethe izinhlayiya ezincane ukuthi bayakwazi ugcwalise umgodi emhlabathini ngisho owayemude encane.

usimende Ukwakheka umjovo ubuchwepheshe

Geology ukuze kwakhiwe isiza anqume izinga inhlabathi ukunquma isinyathelo ukuze babaqinise. ubuchwepheshe emgomeni cementation simiswe ngalendlela lelandzelako:

1. Drilling imithombo 112-132 mm ububanzi kumuntu ukujula kusengaphambili.
2. Ukukhulisa sokuprakthiza okuphakelayo usimende nosimende, emoyeni, emanzini ukujikeleza kanyekanye zokusabalalisa kangcono ukwakheka. ngaleyo ndlela slurry lugcwele yonke izimbotshana phansi.
3. Qedela ekususweni Rig kanye ukucwiliswa ku uncured usimende ukuqinisa yezinyoni nemigoqo yensimbi ukufeza inhlabathi kuqiniswa kangcono. Okwangempela basengozini enkulu kwenhlabathi, ezifana ukusondela ukuba umzimba ngamanzi noma ezingeni lelisetulu komhlaba.
4. Umklamo ishiywa amasonto ambalwa ukuqedela solidification yesixazululo. Ngalesi sikhathi, kubalulekile ukumisa zonke ukwakhiwa usebenza ukuvimbela kokuyekethisa ubuqotho okuholela yinqwaba ukhonkolo-abalwazi kahle ulimi.

Phakathi Ukwakheka imishini sidla ngaphansi kwengcindezi okusezingeni eliphezulu ukunikeza Ukungena lwalo ezijulile inhlabathi izingqimba. Ngu jet ubuchwepheshe grouting ingalungiswa izisekelo, isisekelo imigodi futhi izakhi ziyaqothuka ovundlile.

Ukusebenzisa indlela kakhulu ngcono izici grouting obhekene azinze. Ngemva le nqubo, ungakwazi ukwakha izakhiwo eziyinkimbinkimbi ngaphandle kokwesaba ngokuhlaziya isisekelo futhi ukuwohloka okuphelele izakhiwo.
