I-Grouting yamatye sisixhobo sokwakha esikhethekileyo esisetyenziselwa ukuvala izikhewu zamatye, ukuphucula imiphumo yokuhombisa kunye nokuzinza kwesakhiwo, kwaye ifuna ukunamathela okuhle, ukumelana neentanda, ukumelana nemozulu kunye nokumelana namanzi.Umgubo wepolymer ophinda uqhekeke (RDP)yinxalenye ebalulekileyo eguquliweyo kwifomula ye-grouting yamatye, enokuphucula kakhulu ukusebenza kwezinto ze-grouting, okwenza ibonise ukuqina okungcono kunye namava okwakha kwiiprojekthi zangaphakathi nangaphandle.
1. Iimpawu ezisisiseko kunye nendlela yokusebenza kwe-RDP
I-RDP yi-polymer powder ephinda inyibilike elungiselelwe ngenkqubo yokomisa nge-spray. Izinto eziqhelekileyo ezisisiseko ziquka i-ethylene-vinyl acetate (EVA), i-acrylate copolymer kunye ne-styrene-acrylate copolymer. I-RDP ingaphinda inyibilike ukuze yenze i-polymer emulsion xa idibana namanzi, kwaye yenze ifilimu ye-polymer yenethiwekhi enemveliso ye-samente hydration okanye izizalisi ukuphucula ukuguquguquka kunye namandla okubopha ngokubanzi kwezinto ze-grouting. Kwi-grouting yamatye, le filimu ye-polymer inokwenza "ibhulorho yokuncamathelisa" kumphezulu welitye, ikwazi ukumelana ngempumelelo noxinzelelo olubangelwa kukwanda kobushushu kunye nokuxinana, kwaye inciphise umngcipheko wokuqhekeka.
2. Phucula ukunamathela kunye nokumelana nokuqhekeka
I-grouting yamatye idla ngokusetyenziselwa ukuvala izikhewu kwilitye lendalo, imabula, igranite kunye nezinye izinto. Ezi substrates zinomphezulu oxineneyo kunye nokufunxwa kwamanzi kancinci, kwaye zinamathela kancinci kwi-mortar eqhelekileyo yesamente. Emva kokongeza i-RDP, ifilimu ye-polymer eguquguqukayo eyenziwe kwizinto ze-grouting iphucula kakhulu ukunamathela kwi-substrate yamatye, kwaye inokugcina ukubopha okuhle nokuba kwindawo enomahluko omkhulu wobushushu, ithintela ukuqhekeka nokuwa. Kwangaxeshanye, i-RDP inika izinto ze-grouting ukuguquguquka okuthile, okunokunciphisa ngempumelelo iintanda ezibangelwa kukuncipha okanye amandla angaphandle kumphezulu welitye.
3. Ukuphucula ukumelana namanzi kunye nokungangenwa kwamanzi
Izinto zokufaka ilitye zinokuba mhlophe, ziqhekeke okanye ziwe xa zibekwe kwindawo efumileyo ixesha elide. Ifilimu yepolymer exineneyo eyenziwe yi-RDP kwinkqubo yokufakela ilitye inokunciphisa ii-capillary pores, iphucule ukungenwa kwamanzi kwezinto kunye nokumelana namanzi, kwaye ngaloo ndlela ithintele ngokufanelekileyo ukufuma ekungeneni ngaphakathi kwelitye. Oku kubaluleke kakhulu kwi-stone grouting kwiindawo ezimanzi okanye ezibonakala ngathi ziindawo zokuhlambela, iikhitshi kunye neendawo zangaphandle.
4. Phucula ukusebenza kolwakhiwo
Ukungeniswa kwe-RDP akupheleli nje ekuphuculeni iimpawu zoomatshini zezinto ezigqityiweyo zokufaka i-grouting, kodwa kukwaphucula namava ayo okwakha. I-RDP inokuphucula ukugcinwa kwamanzi kwi-slurry kwaye ithintele ukuqhekeka okubangelwa kukulahleka kwamanzi kwangoko; kwangaxeshanye, iphucula ukusebenza kakuhle kunye nokugeleza kwamanzi, okwenza kube lula ukuba i-grouting izalise ii-scuffs ezincinci kwaye ifumane umphezulu ogudileyo nothe tyaba. Umphezulu we-slurry emva kokwakhiwa kulula ukuwucoca, kunciphisa umngcipheko wokungcolisa umphezulu welitye.
5. Ukuphucula ukumelana nemozulu kunye nobuhle bayo
Kwi-grouting yamatye angaphandle, ukumelana nokuguga kwe-UV kunye nokumelana nokunyibilika komkhenkce ziimpawu ezibalulekileyo zokulinganisa ukusebenza kwexesha elide. I-RDP inika izixhobo ze-grouting ukumelana nemozulu entle kwaye inokugcina isakhiwo sizinzile phantsi kobushushu obuphezulu nobuphantsi kunye neendawo zomjikelo owomileyo nomanzi. Ukongeza, ukuguquguquka okuphezulu kwe-RDP kunokunciphisa umahluko wombala okanye ukuxobuka okubangelwa kuxinzelelo lokusingqongileyo kwaye kwandise ubuhle bomphezulu welitye.
6. Idosi ye-RDP kunye nokuphuculwa kwefomula
Ubungakanani be-RDP kwizinto zokudibanisa amatye kufuneka bumiselwe ngokwezinto ezifana nohlobo lwe-substrate, ububanzi bomthungo, kunye nendawo yokwakha, kwaye ngokubanzi yi-2% ukuya kwi-6% yobunzima bezinto ezisimende. Umlinganiselo ophezulu kakhulu unokukhokelela ekwandeni kokuncipha kunye neendleko eziphezulu, ngelixa umthamo ophantsi kakhulu usenokungafezekisi ukusebenza okulindelweyo. Ke ngoko, kwimveliso yokwenyani, kuyimfuneko ukwenza ngcono le fomula ngokusebenzisa iimvavanyo kwaye uyilungise kunye nezinye izongezo ezifana ne-cellulose ether, i-defoamer kunye ne-filler ukuze kufunyanwe isiphumo sokwakha kunye nokusetyenziswa esingcono.
Njengenxalenye ebalulekileyo eguquliweyo yezisombululo ze-grouting zamatye,I-RDP inokuphucula ngempumelelo ukunamathela, ukuguquguquka, ukumelana namanzi kunye nokumelana nemozulu kwezinto zokudibanisa i-grouting, kwaye iphucula kakhulu ukusebenza kolwakhiwo kunye nomgangatho wemveliso egqityiweyo. Ukusetyenziswa kwayo kwilitye lendalo, imabula kunye negranite kunokunceda ukwandisa ubomi beprojekthi kunye nokugcina ubuhle bokugqitywa kwelitye. Kwixesha elizayo, ngokuphuhliswa kwe-RDP esebenza kakuhle kwaye inobuhlobo nokusingqongileyo, izisombululo ze-grouting zamatye ziya kuphuculwa ngakumbi zibe namandla aphezulu, ukuncitshiswa okuncinci kunye nokuqina ixesha elide.
