Mkhalidwe woyambira wa kuponda ndi kutambasula kwa polypropylene ya njira zitatu

1. Zinthu zofunika kwambiri pa kupopera ndi kutambasula polypropylene panjira zitatu

(1) Tanthauzo ndi njira yopangira

Polypropylene yokhala ndi njira zitatu yolumikizira tensile geogrid ndi mtundu watsopano wa zinthu zolimbitsa geotechnical zomwe zimapangidwa ndikuwongoleredwa pogwiritsa ntchito uniaxial tensile geogrid ndi biaxial tensile geogrid. Njira yopangira ndi yakuti polypropylene imagwiritsidwa ntchito ngati zinthu zazikulu zopangira, kudzera mu extrusion, plate forming ndi punching processes, kenako longitudinal ndi transverse stretching, ndi z Directional stretching, yomwe imapangidwa powonjezera direction imodzi stretching ku three-dimensional direction.

(2) Makhalidwe a kapangidwe kake

1. Kapangidwe kapadera ka katatu

• Kapangidwe kameneka ndi kokhazikika, kali ndi kukhazikika koyenera kuposa ma gridi olunjika mbali imodzi ndi ma gridi olunjika mbali zonse ziwiri, ndipo amatha kunyamula katundu wolunjika mbali zambiri nthawi imodzi, motero kufalitsa katundu bwino kwambiri.

• Makhalidwe olimba m'mbali zitatu

• Ili ndi mphamvu yolimba yogwira mbali zitatu, zomwe zimapangitsa kuti izitha kuletsa ndikuwongolera kukokoloka kwa nthaka mbali zosiyanasiyana. Ili ndi mphamvu yolimba osati mbali zonse ziwiri zokha, komanso imatha kuwonjezera kukangana ikakhudzana ndi subgrade ndikuletsa kukokoloka kwa nthaka ya subgrade.

2. Ubwino wa magwiridwe antchito a polypropylene yokhomerera njira zitatu ndi geogrid yolimba

(1) Kapangidwe ka makina

1. Mphamvu yayikulu yokoka

• Chogulitsacho chili ndi mphamvu yayikulu yokoka, chimatha kusintha malinga ndi zofunikira pamavuto m'malo osiyanasiyana aukadaulo, ndipo chingagwiritsidwe ntchito polimbitsa zida zaukadaulo zomwe zimafunika kunyamula mphamvu zazikulu yokoka, monga madamu ndi ma subgrade osiyanasiyana.

• Kukhazikika kwakukulu

• Chifukwa cha kapangidwe kake kapadera ka mbali zitatu, imatha kupereka njira yabwino yolumikizirana yothandiza kwambiri pakunyamula mphamvu ndi kufalikira kwa nthaka, zomwe zimatha kusintha kuti zigwirizane ndi kulimbitsa maziko okhazikika a malo akuluakulu ndikuwonjezera bwino kukhazikika kwa maziko. Mwachitsanzo, imagwira ntchito yofunika kwambiri pakulimbitsa makoma a misewu yayikulu ndi njanji komanso kulimbitsa makoma osungiramo zinthu 34.

(2) Kulimba

1. Moyo wautali wautumiki

• Zipangizozi zimakhala zolimba kwambiri, sizimawonongeka mosavuta mukazigwiritsa ntchito kwa nthawi yayitali, zimatha kuchepetsa ndalama zokonzera panthawi yogwiritsa ntchito, ndipo ndizoyenera mapulojekiti omwe amafunika kulimba kwambiri, monga ma eyapoti akuluakulu, malo oimika magalimoto, ndi zina zotero.

• Kukana bwino dzimbiri

• Zipangizo za polypropylene zokha zili ndi mphamvu yolimbana ndi dzimbiri, zomwe zimatha kusunga magwiridwe antchito okhazikika pansi pa nthaka ndi malo osiyanasiyana, ndikuchepetsa chiopsezo cha kuwonongeka kwa magwiridwe antchito azinthu chifukwa cha dzimbiri.

(3) Ubwino wina

1. Wopepuka

• Ndi yopepuka, imatha kusintha maukonde achitsulo cholemera, ndi yosavuta kunyamula ndi kuyika panthawi yomanga, imatha kukonza bwino ntchito yomanga, kuchepetsa zovuta ndi ndalama zomangira, mwachitsanzo, ikagwiritsidwa ntchito ngati choteteza, denga lonyenga, ndi zina zotero. mumigodi yapansi panthaka m'migodi ya malasha, kulemera kopepuka ndikosavuta kugwiritsa ntchito.

• Kuchita bwino kwambiri

• Ili ndi mtengo wotsika komanso magwiridwe antchito okwera mtengo pakati pa zinthu zambiri zopangira geosynthetic. Imatha kuwongolera bwino ndalama za uinjiniya pamene ikukwaniritsa zosowa za uinjiniya. Chifukwa chake, ndi yotchuka kwambiri kwa anthu ndipo ili ndi ntchito zosiyanasiyana, kuphatikiza koma osati zokhazo pa madamu osiyanasiyana, ma subgrade, ndi malo otsetsereka. Chitetezo, ma eyapoti, malo oimika magalimoto ndi mapulojekiti ena.
