Qhov xwm txheej yooj yim ntawm peb txoj kev polypropylene punching thiab ncab geogrid

1. Qhov xwm txheej yooj yim ntawm peb txoj kev polypropylene punching thiab ncab geogrid

(1) Kev txhais thiab cov txheej txheem tsim khoom

Peb-txoj kev polypropylene punching tensile geogrid yog ib hom tshiab ntawm cov khoom siv geotechnical reinforcement tsim thiab txhim kho raws li uniaxial tensile geogrid thiab biaxial tensile geogrid. Cov txheej txheem ntau lawm yog tias polypropylene yog siv ua cov khoom siv raw tseem ceeb, los ntawm extrusion, phaj tsim thiab punching cov txheej txheem, thiab tom qab ntawd longitudinal thiab transverse stretching, thiab z Directional stretching, uas yog tsim los ntawm kev ntxiv ib qho kev taw qhia ncab rau peb-seem.

(2) Cov yam ntxwv ntawm cov qauv

1. Cov qauv peb sab tshwj xeeb

• Cov qauv no ruaj khov, muaj kev ruaj khov dua li cov grids unidirectional thiab bidirectional grids, thiab tuaj yeem dais ntau qhov kev thauj khoom tib lub sijhawm, yog li faib cov khoom thauj tau zoo dua.

• Cov yam ntxwv tensile hauv peb-seem kev taw qhia

• Nws muaj lub zog tensile muaj zog hauv peb-seem, uas ua rau nws paub zoo txog qhov cuam tshuam ntawm kev tiv thaiv thiab tswj kev yaig av hauv ntau qhov kev taw qhia. Nws muaj lub zog tensile zoo tsis yog tsuas yog nyob rau hauv qhov ntev thiab transverse kev taw qhia, tab sis kuj tuaj yeem ua rau muaj kev sib txhuam thaum nws sib cuag tag nrho nrog lub subgrade thiab tiv thaiv kev yaig av ntawm lub subgrade.

2. Kev ua tau zoo ntawm peb txoj kev polypropylene punching thiab tensile geogrid

(1) Cov khoom siv kho tshuab

1. Lub zog tensile siab

• Cov khoom nws tus kheej muaj lub zog tensile loj, tuaj yeem hloov kho rau qhov xav tau kev ntxhov siab hauv ntau yam kev tsim kho vaj tse, thiab tuaj yeem siv rau kev txhawb nqa ntawm cov khoom siv engineering uas xav tau lub zog tensile loj, xws li ntau yam pas dej thiab subgrades.

• Kev ruaj khov siab

• Vim nws txoj kev tsim peb txoj kev tshwj xeeb, nws tuaj yeem muab lub kaw lus sib txuas zoo tshaj plaws ntawm kev tuav lub zog thiab kev sib kis hauv av, uas tuaj yeem hloov kho rau kev txhawb nqa ntawm thaj chaw loj thiab txhim kho kev ruaj khov ntawm lub hauv paus. Piv txwv li, nws ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa txoj kev loj thiab txoj kev tsheb ciav hlau thiab kev txhawb nqa phab ntsa 34.

(2) Kev Ruaj Khov

1. Lub neej ua haujlwm ntev

• Cov khoom siv no muaj lub zog ruaj khov, tsis yooj yim puas tsuaj thaum siv ntev, tuaj yeem txo cov nqi txij nkawm thaum siv, thiab tsim nyog rau cov haujlwm uas muaj qhov yuav tsum tau ua kom ruaj khov, xws li tshav dav hlau loj, chaw nres tsheb, thiab lwm yam.

• Kev tiv thaiv xeb zoo dua

• Cov khoom siv polypropylene nws tus kheej muaj qee yam kev tiv thaiv xeb, uas tuaj yeem tswj tau qhov ua tau zoo nyob rau hauv cov av sib txawv thiab cov xwm txheej ib puag ncig, thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm cov khoom siv los ntawm kev xeb.

(3) Lwm yam zoo

1. Sib dua

• Nws yog sib dua, tuaj yeem hloov cov hlau hnyav mesh, yooj yim rau kev thauj mus los thiab kev teeb tsa hauv cov txheej txheem tsim kho, tuaj yeem txhim kho kev tsim kho kom zoo, txo qhov nyuaj thiab tus nqi ntawm kev tsim kho, piv txwv li, thaum nws tuaj yeem siv los ua kev txhawb nqa tiv thaiv, ru tsev cuav, thiab lwm yam hauv kev khawb av hauv cov chaw khawb thee, qhov hnyav sib dua yog qhov yooj yim rau kev ua haujlwm.

• Kev ua tau zoo ntawm tus nqi

• Nws muaj tus nqi qis thiab kev ua tau zoo ntawm ntau yam khoom geosynthetic. Nws tuaj yeem tswj tau tus nqi engineering thaum ua tau raws li qhov xav tau engineering. Yog li ntawd, nws nrov heev nrog cov pej xeem thiab muaj ntau yam kev siv, suav nrog tab sis tsis txwv rau ntau yam pas dej, subgrades, thiab slopes. Kev tiv thaiv, tshav dav hlau, chaw nres tsheb thiab lwm yam haujlwm.
