Kev kuaj xyuas qhov zoo ntawm cov nyom dag suav nrog dab tsi?Muaj ob qho qauv tseem ceeb rau kev kuaj xyuas qhov zoo ntawm cov nyom dag, uas yog cov qauv zoo ntawm cov khoom nyom dag thiab cov qauv zoo ntawm qhov chaw ua cov nyom dag. Cov qauv khoom suav nrog cov qauv zoo ntawm cov nyom dag thiab cov qauv tshuaj xyuas cov khoom siv ntawm cov nyom dag; cov qauv ntawm qhov chaw suav nrog qhov chaw tiaj tus, qhov nkhaus, kev tswj qhov loj ntawm qhov chaw thiab lwm yam qauv.
Cov qauv tshuaj xyuas khoom zoo: Cov nyom dag yog ua los ntawm PP lossis PE cov ntaub ntawv. Cov nyom filaments yuav tsum tau kuaj xyuas los ntawm cov koom haum kuaj xyuas nruj. Cov chaw tsim khoom nyom dag yuav tsum muaj daim ntawv pov thawj tiv thaiv hluav taws thib ob SGS, cov tshuaj lom thiab cov tshuaj lom, tiv thaiv xeb, hnav-resistant daim ntawv pov thawj, thiab lwm yam.; tib lub sijhawm, cov nyom Cov nplaum siv rau hauv qab kuj cuam tshuam rau qhov zoo ntawm cov nyom dag, thiab cov nplaum yuav tsum muaj kev tiv thaiv ib puag ncig thiab kev nyab xeeb daim ntawv pov thawj.
Cov qauv tshuaj xyuas cov khoom zoo: uas yog, kev ncab cov fiber nyom dag, kev sim tiv thaiv kev laus, xim nyom dag thiab lwm yam qauv tshuaj ntsuam nyom dag. Qhov ntev ntawm cov nyom dag hauv qhov ntev yuav tsum tsis pub tsawg dua 15% thiab qhov ntev ntawm cov nyom dag yuav tsum tsis pub tsawg dua 8%; qhov ntev ntawm cov nyom dag yuav tsum tsawg kawg yog 30KN / m thiab qhov ntev ntawm cov nyom dag yuav tsum tsis pub tsawg dua 25KN / m; Qhov ntev thiab qhov ntev ntawm cov nyom dag ua tau raws li cov qauv, thiab qhov zoo ntawm cov nyom dag tau txhim kho ntxiv.
Cov qauv kuaj xim: Xim ntawm cov nyom yuav tsum tau kuaj seb puas tiv taus sulfuric acid. Xaiv cov qauv nyom cuav kom raug thiab muab tso rau hauv 80% sulfuric acid rau 3 hnub. Tom qab peb hnub, saib seb cov xim ntawm cov nyom puas hloov. Yog tias cov xim ntawm cov nyom tsis hloov, ces yuav pom tias cov xim ntawm cov nyom cuav ua tau raws li cov qauv zoo ntawm cov nyom cuav.
Tsis tas li ntawd xwb, cov nyom dag yuav tsum tau kuaj xyuas kev laus. Tom qab kuaj xyuas kev laus, lub zog tensile ntawm cov nyom tau txiav txim siab tias yuav tsum muaj tsawg kawg yog 16 MPa hauv qhov kev coj mus ntev thiab tsis tsawg dua 8 MPa hauv qhov kev coj mus hla; lub zog rhuav tsis tsawg dua 25 KN / m hauv qhov kev coj mus ntev thiab 20 KN / m hauv qhov kev coj mus hla. m. Tib lub sijhawm, qhov zoo ntawm cov nyom dag kuj yuav tsum muaj cov qauv tiv thaiv hluav taws. Rau kev tiv thaiv hluav taws, xaiv cov qauv nyom kom tsim nyog thiab sau lawv nrog xuab zeb zoo ntawm 25-80 kg / ㎡ rau kev sim. Yog tias txoj kab uas hla ntawm qhov chaw kub hnyiab yog nyob hauv 5 cm, nws yog qib 1, thiab cov nyom dag yog hluav taws-pov thawj. Kev sib deev yog raws li tus qauv.
Tus qauv rau kev tshuaj xyuas qhov zoo ntawm qhov chaw paving yog tswj qhov tiaj tiaj ntawm qhov chaw mus rau 10 hli, thiab siv txoj kab me me 3m los ntsuas kom tsis txhob muaj qhov yuam kev loj; thaum paving nyom, xyuas kom meej tias qhov chaw inclination raug tswj tsis pub dhau 1%, thiab ntsuas nrog ib theem; qhov inclination raug tswj, Yog li ntawd cov nyom tuaj yeem ntws tau zoo. Tib lub sijhawm, qhov yuam kev loj ntawm qhov ntev thiab dav ntawm cov nyom dag raug tswj kom txog 10 hli. Siv tus pas ntsuas los ntsuas thiab khaws qhov yuam kev kom tsawg li tsawg tau.
Cov khoom siv dag nyom tsuas yog tuaj yeem ua ke hauv qhov chaw paved los ntawm kev tswj hwm txhua qhov parameter.Cov khoom siv nyom dagCov ntsuas qhia tau zoo heev thiab ua tau raws li cov qauv. Yog tias qhov yuav tsum tau ua ntawm qhov chaw ua si tsis ua tau raws li cov qauv, cov nyom dag yuav tsis muaj peev xwm qhia nws qhov txiaj ntsig zoo tshaj plaws. Yog li ntawd, cov qauv zoo rau cov nyom dag xav tau kev koom ua ke ntawm cov khoom zoo thiab cov qauv ntawm qhov chaw, ob qho tib si yog qhov tseem ceeb.
