Yuav ua li cas grouting cov ntaub ntawv txhim kho durability

Nrog rau kev siv dav dav ntawm lub zog siab uas tsis yog-shrinking grouting tshuaj admixtures thiab ultra-fine ntxhia admixtures, Tuam Tshoj tus uas twb muaj lawm reinforcement grouting ratio tsim specifications yuav tsis tau raws li qhov tseeb xav tau ntawm high-kev ua tau zoo grouting khoom thiab kev tsim kho. Nyob rau hauv lub hauv paus ntawm kev ua kom ntseeg tau lub zog ntawm cov khoom siv grouting, tsim nyog xaiv cov khoom siv zoo thiab txo cov cement kom siab tshaj plaws yog txoj hauv kev zoo los txhim kho ntau txoj haujlwm ntawm cov ntaub ntawv grouting, thiab tseem yog cov kev tshawb fawb thiab kev kho mob ntawm cov khoom siv. cov ntsiab lus tseem ceeb ntawm cov ntaub ntawv muaj zog grouting. Yuav ua li cas los txhim kho lub durability ntawm lub grout?

1. Kev txiav txim siab ntawm proportioning Tus qauv proportioning yog xav txog qhov proportioning ntawm grouting cov ntaub ntawv nyob rau hauv cov nqe lus ntawm kev ua hauj lwm, durability, thiab lwm yam, yog li cov khoom siv ntxiv dag zog rau cov khoom siv yuav siv dej ntau dua kom ua tiav cov dej ntws, thiab cov cement txheeb ze qhov ntau npaum li cas kuj tseem muaj. siab. Qhov piv ntawm cov khoom siv ntxiv dag zog no kuj tseem muaj kev pheej hmoo ntau dua ntawm deformation.

2. Kev koom ua ke ntawm cov hmoov ntxhia zoo tuaj yeem hloov tau ib feem ntawm cov cement kom txo cov cua sov ntawm cov dej, thiab tuaj yeem txo qhov kev hem thawj ntawm cov cement ntau npaum li cas kom qhuav shrinkage. Vim tias qhov zoo ntawm cov pob zeb hauv av yog qhov zoo dua li cov cement, nws tuaj yeem ua kom cov yas viscosity ntawm cov khoom siv grouting tom qab sib tov. Tom qab ntawd ua kom cov compactness ntawm cov khoom siv grouting, txhim kho qhov tsis muaj zog interface cheeb tsam, thiab ua tiav cov txiaj ntsig ntawm kev txhim kho cov durability ntawm cov khoom siv grouting.
