Yintoni na cementation yemihlaba nalapho kuyimfuneko

Umhlaba grouting isetyenziselwa ukuze ndinabele uzinzo umhlaba zokumiswa elandelayo kwezakhiwo okanye ezinye sobuciko. Le nqubo efanelekileyo kwiindawo ezithandwa kukhukuliseko kunye landslides. Le nkqubo isoloko lwenziwa kwiindawo Amathafa kufuphi namanzi okanye kwiindawo itafile eliphezulu lamanzi.

Phakathi zonke iindlela ezisetyenziswayo ukomeleza grouting umhlaba yeyona ndlela ixhaphakileyo. It phakathi kwezinye iindlela ezingabizi kakhulu, kodwa akukho ngaphantsi kwe olusebenzayo ezifanayo, kwaye kunceda ekwandiseni ethwele umthamo umhlaba, nto leyo eza kunceda ukuba sandise ubomi inkonzo lwezakhiwo.

enkulu isicelo

Grouting isoloko isetyenziswa kwishishini lokwakha ukuba:

1. Ukuyila izakhiwo ezweni ezingazinzanga.
2. Works ukulungiswa isebenza kwizityalo kwelindle.
3. Ukuqiniswa okwethutyana okanye ngokusisigxina zeentsebenzo komhlaba.
4. Ukomeleza kweziseko ezikhoyo.
5. Ukomeleza lomhlaba karst.

Yokukhulisa kwenziwa nezinye indlela cementation yendalo izalisa lweHo- emhlabeni, ngaloo ndlela kuphuculwe nokuqina kwayo. Le nkqubo kwakhona echaphazelekayo xa nezingacwangciselwanga kubonakele iindawo zomhlaba mobile kakhulu kwizakhiwo.

design

Geology zokwakha ludlala indima ebalulekileyo. Kuyilo isakhiwo ubhatalwa kakhulu ingqalelo umgangatho womhlaba, indawo, amanzi aphantsi komhlaba kunye nezinye izinto ezinokuthi kunokunciphisa ubomi ukusebenza yokwakha. Kuyilo grouting kubalulekile ukujonga izinto ezilandelayo:

• Zone lokubopha kunye ethwele amandla emhlabeni.
• indlela grouting. Oku kunokwahluka ukusuka mali ukhetho kunye kunokwembiwa ezahlukileyo injecting isisombululo esebenzisa injector nokusetyenziswa kwezixhobo ezibizayo.
• Yenziwe ngoobani kunye nobungakanani udaka lwesamente. Kuxhomekeke kwiziphumo ezinqwenelekayo, lexinene wokuqala womhlaba, zesamente kunye plasticizers ezongezelelweyo kunye accelerators.
• Lokulawula umgangatho womsebenzi owenziwa. Kuba iimvavanyo yokusebenza yayo eziqhutywa iipropati emzimbeni mechanical komhlaba emva grouting.

Ezi ngongoma ziya kukunceda iqalise le nkqubo kakuhle ngakumbi ezingabizi.

Jet grouting Soil

Kuyinto indlela yokomeleza ngokuthi injecting grout ngokusebenzisa injectors kungena amaqula kugrunjwa. Ngenxa yamakariti umsebenzi wokwakha isamente kuyilwa, awothi efunekayo ukuze kuqiniswe ngakumbi ngeentonga yesinyithi.

Ngexesha umsebenzi isisombululo ngamanzi-isamente ngokwahlukeneyo ukutya, umoya namanzi, leyo xa udala isakhelo Ukuqinisa lwesamente. Kulo mzekelo, isixhobo monitor ibonisa inkcazelo epheleleyo malunga nenkqubo.

Izinto eziluncedo ze jet grouting

Izinto eziluncedo yale ndlela ziquka:

• ukusebenza - uphumezo ngokukhawuleza ngemisebenzi;
• ithuba lomsebenzi kwezinye iindawo emhlabeni ngaphezulu, ngaphantsi kwenqanaba aphantsi komhlaba;
• kwizinga eliphezulu inkqubo;
• ukungabikho ingxolo kunye ukungcangcazela, nto leyo evumela iintshukumo ezithile nokuba kwindawo zokuhlala ezindaweni ezinabantu;
• xa besebenza ngaphakathi kwisakhiwo zingasetyenziswa kusetyenziswa rigs ezincinane.

Ezi ntlawulo zithathelwa ingqalelo xa ukhetha indlela yokomeleza umhlaba ezingazinzanga.

ukuqinisa iziseko

cementation ubuchule idla ngokusetyenziswa ukuphucula zizathu ezikhoyo. Kulo mzekelo, isiseko kuphela ufumana inkxaso eyongezelelweyo ukuthintela imbonakalo neentanda ezindongeni kwaye ukuwa ngokupheleleyo ezi zakhiwo.

Isixhobo uba ukuhamba eliphezulu, elikuvumela ukuba uyibeke ntshi kwisakhiwo. ubukhulu ezincinane kunye nezixhobo lwemasti mobile ukuvumela ngaphandle umsindo, ukungcangcazela.

Isiseko kuphela ukuba ziyanyuswa kusetyenziswa iintlobo ezifana zesamente:

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

Ezi amabakala ziqulathe amasuntswana amancinane ukuba nako ukubahluthisa lweHo- osemhlabeni, kude ubukhulu encinane.

isamente ziphene ukubunjwa technology

Geology zokwakha kunceda ukuqinisekisa umgangatho umhlaba ukumisela amanyathelo ngakumbi ukuze awomeleze. technology Umgangatho cementation imi ngolu hlobo lulandelayo:

1. yokugrumba 112-132 mm ubukhulu ukuya kubunzulu kwangaphambili.
2. Ukuphakamisa ibumba drill feed isamente, umoya, amanzi kunye ujikeleziso ngaxeshanye ukuze ulwabiwo olungcono nokwakheka. Ngaloo ndlela oluludaka igcwalisa zonke ukuqanda emhlabeni.
3. Zalisa ukususwa isixhobo kunye ubhaptizo kwi uncured isamente wezifundo Nentolongo imivalo yesinyithi ukuphumeza uzinziso ngcono umhlaba. Okwenziweyo basengozini enkulu yokuba landslides, ezifana nokuba kufutshane umzimba ngamanzi okanye inqanaba eliphezulu aphantsi komhlaba.
4. Uyilo usele iiveki ezimbalwa ukugqiba Ukuqinisa yesisombululo. Ngeli xesha, kubalulekile ukuba sokumisa ulwakhiwo isebenza ukunqanda kokunikezela ngesidima onesiphumo zitsho concrete-abangakumbi.

Ngexesha ukwakheka yokomba ondliwa phantsi koxinzelelo oluphezulu ukubonelela umthondo yayo ibe ingxenye yaso emhlabeni. Ngu jet ubuchwepheshe grouting ingalungiswa iziseko, libe sisigingqi isiseko nezinto ukudleka tyaba.

Ukusetyenziswa indlela kakhulu kuphucula iimpawu grouting onoxanduva azinze. Emva kwale nkqubo, unako ukwakha izakhiwo olunzima yokoyika ngokuhlaziya isiseko kunye nokuwa olupheleleyo lwezakhiwo.
