Ua ib hom khoom siv sib xyaw ua ke tshiab, cov cementitious mats tau txais kev siv dav dav - kev kho dej ntws, kev tiv thaiv txoj kev, kev tsim cov kwj dej, thiab cov haujlwm kho dua tshiab - ua tsaug rau lawv cov txiaj ntsig tshwj xeeb: "kev kho kom zoo los ntawm dej, kev teeb tsa sai, thiab kev ruaj khov." Txhawm rau kom ntseeg tau tias cov khoom ua haujlwm tau zoo tshaj plaws, Shandong Hongyue Environmental Engineering Co., Ltd. tau siv ntau xyoo ntawm kev tsim khoom thiab kev paub txog kev tsim kho kom ua tiav cov txheej txheem siv rau cov cementitious mats. Cov lus qhia no tsom mus rau plaub theem tseem ceeb - kev npaj cov qib hauv qab, kev tso thiab kev khi, kev kho kom zoo los ntawm dej, thiab kev saib xyuas tom qab kev teeb tsa - yog li ua haujlwm ua kev tiv thaiv zoo rau qhov zoo ntawm qhov project.
I. Kev Npaj Qib Hauv Qab: Sib npaug, Ruaj Khoov, thiab Tsis Muaj Khoom Siv Ntses Thiab Cov Khib Nyhiab
Ua ntej kev tsim kho, qhov chaw ua haujlwm yuav tsum tau ua kom tiaj tiaj. Tshem tawm tag nrho cov nroj tsuag, cov cag ntoo, cov pob zeb ntse, thiab cov av xoob kom huv si kom ntseeg tau tias qhov chaw hauv av tsis muaj qhov tawm lossis qhov khoob. Lub hauv paus tsis muaj zog yuav tsum tau siv cov av nplaum-av sib xyaw (feem ntau yog 3: 7 piv); qhov twg tsim nyog, yuav tsum tau teeb tsa ib txheej geotextile cushion. Cov kwj dej thiab cov qhov ntxhab yuav tsum tau muab qib kom phim qhov gradient tsim; pom zoo kom muaj qhov ntxhab ntawm 1: 1.5 thiab 1: 3 kom ntseeg tau tias muaj dej ntws zoo thiab lub hauv paus ruaj khov. Kev teeb tsa ncaj qha rau ntawm cov khib nyiab ntse lossis av tsis sib luag yog txwv tsis pub ua kom cov khoom siv lev tawg lossis kev faib tawm tsis sib luag.
II. Kev Txiav thiab Tso: Kev Qhib thiab Kev Sib Tov Txheem
Kev Txiav Kom Tseeb: Txiav cov khoom raws li qhov loj ntawm qhov chaw, cia kom muaj 5% ntawm qhov sib ntswg, thiab khaws qhov dav ntxiv 10-20 cm ntawm cov seams. Kev txiav yuav tsum tau ua thaum cov khoom qhuav, xyuas kom meej tias cov npoo txiav ncaj thiab tsis muaj burrs.
Kev Tso: Tshem cov khoom siv mus rau hauv qab ntawm qhov nqes hav, pib ntawm sab saud mus rau hauv qab. Xyuas kom tseeb tias qhov chaw ntawm daim lev tseem ntev li qub - tsis muaj qhov ntxhib lossis qhov quav - thiab tsis txhob ncab hnyav. Rau cov haujlwm dej thiab kwj dej, cov khoom siv yuav tsum tau muab tso rau hauv qhov kev taw qhia ntawm dej ntws, nrog rau qhov seem sab saud sib tshooj thiab nias rau ntawm qhov seem sab saud.
III. Kev Kho Kom Qhuav Uas Siv Dej: Kev Haus Kom Txaus, Sib Xws, thiab Muaj Kev Tshawb Fawb
Kev siv dej yog kauj ruam tseem ceeb uas txiav txim siab qhov kawg ntawm cov khoom siv:
Tus Qauv Ntim Dej: Siv dej huv tsis pub tsawg dua 9 kg rau ib square meter (rau daim lev tuab 10 hli).
Txoj Kev Siv: Siv lub tshuab tsuag dej uas muaj zog tsawg los txau dej kom sib npaug, ua haujlwm los ntawm ntug mus rau nruab nrab ntawm daim lev. Tsis pub siv lub tshuab tsuag dej siab ncaj qha. Lub Sijhawm Kho: Ua tiav 80% ntawm lub zog tag nrho hauv 24 teev ntawm qhov kub thiab txias hauv chav tsev; kho tag nrho tom qab 72 teev.
Cov Kev Xav Tau Dej: Yuav tsum siv dej tshiab huv; cov dej khib nyiab lossis dej ntsev yuav ua rau qhov zoo ntawm kev kho tsis zoo.
IV. Kev Kho thiab Kev Txij Nkawm: Tswj Qhov Kub thiab Av; Tsis Txhob Cuam Tshuam
Kev Tiv Thaiv Thaum Pib: Rau 7 hnub tom qab nws qhuav lawm, txwv tsis pub taug kev, thauj khoom hnyav, lossis raug dej ntws ceev heev.
Kev Tswj Kub thiab Av noo:
Kub Siab (>30°C): Ua kom ntau zaus ntawm kev txau dej thiab npog nrog cov ntaub thaiv ntxoov ntxoo kom tiv thaiv kev qhuav thiab tawg.
Kub Qis (≤5°C): Npog nrog zaj duab xis rwb thaiv tsev kom tiv thaiv kev khov thiab cov khoom puas tsuaj.
Kho Kev Puas Tsuaj: Yog tias pom muaj qhov khoob lossis qhov, kho lawv tam sim ntawd siv daim ntaub uas ua los ntawm cov khoom siv tib yam ua ke nrog cov tshuaj sealant.
V. Cov Kev Txwv thiab Cov Lus Ceeb Toom Tseem Ceeb
Tsis txhob ua kev tsim kho sab nraum zoov thaum lub caij los nag; kev raug dej ua ntej kev kho kom qhuav tiav yuav ua rau cov khoom puas tsuaj.
Xyuas kom meej tias cov dej faib sib npaug; dej tsis txaus hauv thaj chaw ib cheeb tsam yuav ua rau cov dej kho tsis tiav (lub hauv paus "raw") thiab lub zog tsis zoo.
Tsis txhob khoov cov khoom thaum nyob hauv lub xeev qhuav, vim qhov no tuaj yeem ua rau cov fiber sab hauv tawg yooj yim.
"Rau cov pam cement, lub hauv paus ntsiab lus yog '30% cov khoom zoo, 70% kev tsim kho kom zoo.' Kev ua raws li cov txheej txheem txheem yog qhov lav qhov kawg ntawm kev ruaj khov mus sij hawm ntev, "Tus Thawj Coj Kev Txawj Ntse ntawm Shandong Hongyue Environmental Technology tau hais. Lub tuam txhab cog lus tias yuav muab kev pabcuam tiav, txij thaum pib mus txog thaum kawg - txij li kev muab khoom siv thiab kev taw qhia txog kev txawj ntse mus rau cov phiaj xwm tsim kho kom ntxaws - los pab txhawb kev ua tiav ntawm ntau yam haujlwm engineering.
