Cov ntaub ntawv ntxaws ntxaws
Raws li cov hmoov sib xyaw ua ke, cov hmoov sib xyaw ua ke no muab faib ua cov hlau, cov hlau uas tsis yog hlau uas tawv thiab tsis yooj yim hnav, uas muaj cov khoom sib xyaw ua ke ntawm cov hlau lossis cov hlau uas tsis yog hlau uas tsis yooj yim hnav thiab cov khoom ntxiv tshwj xeeb. Cov hmoov sib xyaw ua ke no raug xaiv raws li lawv cov duab, qib thiab cov khoom siv lub cev thiab lub cev zoo heev.

Scope ntawm daim ntawv thov
Siv rau hauv cov chaw ua haujlwm kev lag luam, cov tsev rau khoom, cov khw muag khoom loj, cov chaw tsim khoom siv tshuab hnyav, chaw nres tsheb, thaj chaw thauj khoom, cov plaub fab thiab lwm cov plag tsev.
Cov yam ntxwv ntawm kev ua tau zoo
Thaum pib ua kom khov, nws yuav sib npaug zos rau saum npoo ntawm cov pob zeb ua vaj tse, thiab tom qab kho tag nrho, nws yuav ua rau cov pob zeb ua vaj tse tuab thiab tawv heev, uas tiv taus siab, tiv taus kev cuam tshuam, tiv taus kev sib txhuam thiab muaj qhov tseeb thiab xim zoo li cov pob zeb ua vaj tse uas tiv taus kev hnav. Nws tuaj yeem tsim ua ke nrog cov pob zeb ua vaj tse, ua rau lub sijhawm ua haujlwm luv dua, thiab tsis tas yuav tsim cov txheej txheem mortar.
Cov yam ntxwv ntawm lub kaw lus
Kev tsim kho yooj yim, nthuav ncaj qha rau ntawm cov pob zeb tshiab, txuag lub sijhawm thiab kev ua haujlwm, tsis tas yuav tsim cov txheej txheem mortar; kev tiv taus kev sib txhuam siab, txo cov plua plav, txhim kho kev cuam tshuam, txhim kho kev tiv thaiv roj thiab roj.
Cov txheej txheem tsim kho
◇ Kev kho qhov chaw ntawm cov pob zeb: siv lub tshuab trowel uas muaj lub disc kom tshem tawm cov txheej slurry uas ntab rau ntawm qhov chaw ntawm cov pob zeb;
◇Cov khoom siv nthuav dav: nthuav 2/3 ntawm cov tshuaj teev tseg ntawm cov khoom siv hauv pem teb uas tawv thiab tiv taus hnav kom sib npaug rau ntawm qhov chaw ntawm cov pob zeb thaum pib teeb tsa, thiab tom qab ntawd txhuam nws nrog lub tshuab ua kom du qis;
◇Scraper leveling: khawb thiab sib npaug zos cov khoom siv hnav-resistant hardened raws li transverse thiab longitudinal direction nrog lub scraper 6-meter;
◇Kev nthuav dav ntau yam khoom siv: nthuav dav 1/3 ntawm cov tshuaj teev tseg ntawm cov khoom siv tiv taus xim uas tawv (rau ntawm qhov chaw ntawm cov khoom siv tiv taus uas tau txhuam ntau zaus), thiab txhuam qhov chaw dua nrog lub tshuab ua kom du;
◇ Kev txhuam nto: raws li qhov tawv ntawm cov pob zeb, kho lub kaum sab xis ntawm cov hniav ntawm lub tshuab txhuam, thiab txhuam qhov nto kom ntseeg tau tias qhov chaw tiaj tus thiab du;
◇ Kev saib xyuas thiab nthuav dav ntawm lub hauv paus: cov plag tsev uas tsis yooj yim hnav yuav tsum tau khaws cia rau ntawm qhov chaw tsis pub dhau 4 txog 6 teev tom qab kev tsim kho tiav, txhawm rau tiv thaiv kom tsis txhob muaj dej ntws sai sai rau ntawm qhov chaw, thiab kom ntseeg tau tias lub zog ntawm cov khoom siv uas tsis yooj yim hnav loj hlob ruaj khov.
