I-GQ-KG (L) / 01/02 Umenzeli Wokuxhuma Ikhebula

Incazelo emfushane:

I-GQ-KG t yakhiwe ngezinto ezinwetshiwe ezincane, isinciphisi sokusebenza samanzi aphezulu, izinto ezahlukahlukene ezingaphili nezakhiwe nge-polymer izinto kanye ne-PO, usimende ongu-42.5. Uketshezi oluhle kakhulu, i-slurry ezinzile, i-degree enhle yokugcwalisa, akukho ukuncipha, ukunwetshwa okuncane, azikho izinto eziyingozi ekuqiniseni. Kuyi-gro

Incazelo Yokukhiqiza

I-GQ-KG t yakhiwe ngezinto ezinwetshiwe ezincane, isinciphisi sokusebenza samanzi aphezulu, izinto ezahlukahlukene ezingaphili nezakhiwe nge-polymer izinto kanye ne-PO, usimende ongu-42.5. Uketshezi oluhle kakhulu, i-slurry ezinzile, i-degree enhle yokugcwalisa, akukho ukuncipha, ukunwetshwa okuncane, azikho izinto eziyingozi ekuqiniseni. Kungukubhalela okushisayo kweziteshi zangaphambi kwengcindezi, amalunga kanye namalunga wamalungu kakhonkolo. Ikhwalithi yomkhiqizo ihlangabezana nezidingo ze-TB / T3192-2008, JTG / TF 50-2011 namanye amazinga

Imininingwane Yokukhiqiza

1.With uketshezi omuhle kakhulu futhi isikhathi ukulahleka, kulula ukucindezela uginindela ukusebenza

Umphumela wokuthuthukisa usobala. Ukunamathisela kunamandla aphezulu (> 50MPa) nokunamathela okuhle ngemuva kokuqina

Akukho ukuncipha noma ukunwetshwa ngemuva kokuncipha, ukuqina okuhle kwevolumu

I-4.I-slurry ayipheli, ingagcina isikhathi eside sokusebenza, i-slurry degree yokugcwalisa yinhle

Alkalali 5.Low, akukho ukugqwala ukuze steel bar. Ayinabo ubuthi, ayinabungozi, iphephile empilweni nasemvelweni

Isicelo

1. Zonke izinhlobo zesitimela kanye nomgwaqo omkhulu - ukugoqa ibhulorho yokugoqa ibhuloho

Umsele we-2.Umhubhe wezakhiwo ezinkulu ezibunjiwe

Ukuqothulwa kwesihogo kwesikhungo samandla enuzi

4.Stop ukuvuza grouting emalungeni ezakhiweni ezahlukene zikakhonkolo

Isetshenziswa kanjani

1.Control water-cement ratio KG (L) 010.33, KG (L) 020.28 enqunywe ngokuhlolwa ngaphambi kokusetshenziswa

2 Ngokuya kwesilinganiso sokuxuba esicacisiwe sokuxuba, isikhathi sokuxuba asikho ngaphansi kwemizuzu engu-4 ~ 5, kufanele sihambisane nezidingo zokunyakazisa, engeza amanzi ukusebenzisa izindlela ezimbili

3.Impompo ye-grouting kufanele ihlanzwe ngaphambi kokugaya. I-slurry kufanele ivuselelwe ngokuqhubekayo ukugcina ukufana nokufudumala kwesilayidi. I-slurry kufanele igcwaliswe kungakapheli imizuzu engama-30

4.Piston ingcindezi futha kufanele isetshenziselwe grouting, futhi ingcindezi grouting akufanele ibe ngaphezu 0.6mpa

Izinhlobo ezihlukene zikasimende ezivela ezindaweni ezahlukahlukene zokukhiqiza zinethonya elikhulu ekusebenzeni kwe-ejenti yokugaya. Kuphakanyiswa ukuthi inani elihamba phambili lokuxuba izinhlobo zikasimende kanye ne-grouting agent kufanele linqunywe ngokuhlolwa ngaphambi kokusetshenziswa. Zama ukukhetha izinhlobo zikasimende ngokuvumelana nezimo okuhle, ukuncipha namandla aphezulu

Iphakheji nokugcina

Lo mkhiqizo uyimpuphu, upakishwe ngezikhwama zepulasitiki ezilukiwe ezifakwe ifilimu lepulasitiki, i-40kg / isikhwama noma i-50kg / isikhwama

Ukumelana nemvula, umswakama nokulimala, kusebenza isigamu sonyaka. Imikhiqizo engashi futhi evuthayo izogcinwa kahle
