Khoom piav qhia
TD-12 yeeb nkab grouting tus neeg sawv cev yog cov khoom tshiab rau grouting qhov.
Cov slurry npaj los ntawm TD-12 tus neeg sawv cev grouting muaj cov kua dej zoo heev thiab cov slurry ruaj khov, thiab muaj qib siab ntawm kev txhaws. Nws muaj adjustable teem sij hawm, micro-expansion, siab flexural zog, thiab siv advanced migration-type xeb inhibitors los tiv thaiv prestressed steel strand steel tuav. Siv cov qauv ntawm cov khoom siv raw, cov khoom zoo yog ruaj khov thiab txhim khu kev qha.
Cov khoom tseem ceeb ua haujlwm
Fluidity zoo heev (lub khob hliav qab fluidity nyob rau hauv qhov ntau ntawm 18 ± 4 vib nas this thiab tuaj yeem hloov kho raws li qhov sib txawv siv).
Micro expansion kev ua tau zoo
Nws muaj cov khoom tiv thaiv xeb rau cov hlau tuav thiab muaj cov neeg tsiv teb tsaws chaw-hom xeb inhibitors.
High flexural zog thiab siab adhesion
Tsis muaj ntshav, zoo heev slurry stability
Nws yog ib qho yooj yim mus use, cov khoom zoo yog ruaj khov, thiab nws yog ib tug high-end khoom.
Daim ntawv thov Scope
Feem ntau yog siv nyob rau hauv prestressed tunnel filling nrog nplaum quab yuam, thauj tog rau nkoj grouting av thauj tog rau nkoj system, anti-kawg grouting ntawm nruam phab ntsa pob qij txha, ntaub thaiv npog, thiab lwm yam.
Cov lus qhia
Qhov pom zoo sib xyaw piv yog 42.5 cement: TD -12 grouting tus neeg sawv cev: sib tov dej=75: 25 (21 ~ 25). Raws li ntau hom cement, kev sim sib xyaw yog txiav txim siab ua ntej.
Thaum sib tov, ntxiv cov dej sib tov uas ua tau raws li qhov yuav tsum tau ua raws li qhov kev sib xyaw ua ke (cov khoom tsis zoo xws li cov pa oxygen ions tsis tuaj yeem tshaj tus nqi teev, thiab dej hiav txwv, dej saline-alkali, thiab lwm yam siv tsis tau), grouting agent thiab cement. Do hauv lub tshuab tov khoom rau 5-10 feeb, siv ob txheej slurry tov khoom.
Ua ntej pouring, lub slurry yuav tsum tau stirred tsis tu ncua kom lub uniformity thiab fluidity ntawm slurry. Lub slurry feem ntau yuav tsum tau siv li ntawm 45-60 feeb.
During perfusion, a piston pressure pump should be used and the Max perfusion pressure should be >1. 0MPa. Thaum siv lub tshuab nqus tsev grouting, lub siab tuaj yeem hloov kho raws li kev sim.
Ntim thiab khaws cia
Cov khoom no yog hmoov, ntim cov khoom pov thawj, 25 kg ib lub hnab. Thaum khaws cia, nws yuav tsum tau muab tso rau hauv qhov chaw txias thiab qhuav. Tsis txhob tso ncaj qha rau hauv pem teb cement. Nws yuav tsum tau muab tso rau ntawm ib tug ntoo pallet thiab npog nrog ib tug noo-pov thawj membrane. Lub txee lub neej yog 9 lub hlis nyob rau hauv thawj ntim.
