Uhlolojikelele lwe-R25 Self-Drilling Hollow Grout Injection Anchor Rod
Ama-anchor rods ngokuvamile afaneleka ukuqinisa ukwesekwa emiseleni yezimayini, emhubheni wamabhuloho, ekuvikelweni komthambeka wokulandela umkhondo, nezinye izindawo. Ngokuvamile, izimbobo zenduku okusetshenzwa kulengwa kuyo zibhobolwa kusetshenziswa i-anchor rod, bese kubekwa ama-anchoring agents afanelekile (ama-resin powder rolls). Khona-ke, amathuluzi anjenge-anchor rod drill asetshenziselwa ukubhoboza induku yesikhonkwane embotsheni yesikhonkwane, ukunyakazisa nokugxilisa i-agent anchore, bese kusetshenziswa amathuluzi afana ne-anchor rod drill ukufaka amantongomane kuyo; Induku yehange yesandla sokudla, eyaziwa nangokuthi amandla alinganayo ensimbi ye-resin anchor rod, yenziwe ngensimbi egoqwe kwesokudla (noma kwesokunxele), enemicu eqhubekayo kanye nobude obugcwele obungaxhunywa ngamantongomane. Isetshenziswa ngokuhambisana namantongomane epuleti lehange ukuze kusekelwe umhubhe. Ibhawodi iwumkhiqizo oshintshwayo webhawodi ye-anti Fried Dough Twists, esebenza kahle kakhulu.
Ukucaciswa Kwentonga Yesikhonkwane Yokujova I-Grout engu-R25 Yokuzibhoboza

Izici ze-self-drilling i-grouting induku yehange
1. Iphephile, ithembekile, futhi iyonga isikhathi.
2. Ukufakwa okulula nokusebenza.
3. Ukukhetha izingcezu zokubhoboza izimo ezihlukene zomhlabathi.
4. I-Grouting isebenza ukuvumelanisa nokubhoboza noma ngemva kokumba. I-Grout ingagcwalisa ama-fractures ngempumelelo.
5. Ama-anchor bar angasikwa futhi andwe ngokucelwa, asetshenziswe ezindaweni eziwumngcingo.
6. Inikeza ingcindezi ephakeme yokubopha kunepayipi yensimbi ebushelelezi kuye ngentambo yamagagasi eqhubekayo.
Izinzuzo zokuzibhoboza induku yehange enezimbobo ezingenalutho
1. Induku yehange eyizimbobo enezimbobo engenalutho ithatha impahla yepayipi lensimbi eliqinile eliqinile elingenamthungo, inqubo yokwakheka kwentambo engaphezulu esheshayo, kanye nezinsiza ezinhle kakhulu, ifinyelela ubunye bokubhoboza, ukugxumeka, ukubambelela kanye neminye imisebenzi yenduku yokuziboleka ihange.
2. Kukhona ucezu lokubhoboza olunamandla okungena aqinile phambi kwentonga yehange enezigodi ezizihambelayo, engangena kalula ezinhlotsheni zamatshe ezihlukene ngaphansi kokusebenza kwemishini evamile yokumba amatshe.
3. Inentambo ye-waveform evamile eqhubekayo futhi ingasetshenziswa njengenduku yokubhoboza ukuze uqedele ukubhoboza izimbobo okusetshenzwa kulengwa kuzo nge-drill bit.
4. Umzimba wenduku yehange wepayipi lokubhoboza awudingi ukukhishelwa ngaphandle, futhi indawo engenalutho ingaba umzila wokukhipha i-grout kusuka ngaphakathi ngaphandle.
5. Isivalo se-grouting singagcina ukucindezela okuqinile kwe-grouting, sigcwalise ngokugcwele izikhala, silungise i-rock mass ephukile, futhi amaphedi namantongomane anamandla amakhulu angadlulisela ngokulinganayo ukucindezeleka kwetshe elizungezile elijulile edwaleni elizungezile, ukufeza umgomo wokubambisana. ukusekela phakathi kwedwala elizungezile kanye nenduku yehange.
6. Ngenxa yokusebenza okuthathu kokukodwa kwalolu hlobo lwenduku yehange, ingakha izimbobo okusetshenzwa kulengwa kuzo futhi iqinisekise imiphumela okusetshenzwa kulengwa kuyo kanye ne-grouting ngaphandle kwesidingo samasu akhethekile njengokuvikela udonga lwe-casing kanye ne-pre grouting ngesikhathi sokwakhiwa ngaphansi kwezimo ezihlukahlukene zamadwala azungezile.
