Kugwiritsa ntchito geogrid yachitsulo-pulasitiki pakulimbitsa ndi kukulitsa subgrade

1. Mfundo yolimbikitsa

• Limbikitsani kukhazikika kwa nthaka
  • Mphamvu yokoka ya geogrid yachitsulo-pulasitiki imayendetsedwa ndi waya wachitsulo wolimba kwambiri wolukidwa ndi warp ndi weft, womwe umapanga modulus yolimba kwambiri pansi pa mphamvu yochepa yopopera. Mphamvu yogwirizana ya nthiti zazitali komanso zopingasa ingathandize kwambiri kutseka kwa gridi panthaka, kuteteza bwino kusamuka kwa nthaka kumbali ndikuwonjezera kukhazikika kwa nthaka yonse. Zili ngati kuwonjezera chimango cholimba kunthaka yotayirira, kuti nthaka ikhale yosavuta kuisintha.
• Kukweza mphamvu yonyamula katundu
  • Kupindika ndi kupindika kwa mawaya achitsulo a nthiti zopingasa ndi zopingasa kumalukidwa mu ukonde, ndipo wosanjikiza wakunja wokutira umapangidwa nthawi imodzi. Waya wachitsulo ndi wosanjikiza wakunja wokutira zimatha kugwirizana, ndipo kutalika kwa kulephera kumakhala kotsika kwambiri (osapitirira 3%). Chigawo chachikulu chopsinjika ndi waya wachitsulo, ndipo kugwedezeka kumakhala kotsika kwambiri. Makhalidwe oterewa amalola geogrid yachitsulo-pulasitiki kunyamula mphamvu yayikulu yokoka mu subgrade, kugawana kupanikizika kwa magalimoto ndi katundu wina pa subgrade, motero kukonza mphamvu yonyamula ya subgrade, monga kuwonjezera mfundo zambiri zolimba mu subgrade yofooka 。
• Wonjezerani kuchuluka kwa kukangana
  • Pogwiritsa ntchito njira yopangira pulasitiki, mapangidwe okhwima amakanikizidwa, zomwe zimawonjezera kuuma kwa gridi ndikuwonjezera kukwanira kwa kukangana pakati pa gridi yachitsulo-pulasitiki ndi nthaka. Izi zimathandiza kuti gridi igwirizane bwino ndi nthaka, zomwe zimathandiza kuti gridi igwire ntchito yolimbitsa bwino ndikuletsa kuti nthaka isagwe pansi pa katundu.

2. Kugwiritsa ntchito mwachindunji pakulimbitsa ndi kukulitsa gawo la pansi

• Kugwiritsa ntchito malo olumikizirana a subgrade yatsopano ndi yakale
  • Chepetsani kukhazikika kosagwirizana：Mu ntchito yokulitsa ndi kumanganso misewu yakale, kukhazikika kosagwirizana kumakhala kosavuta pamalo olumikizirana misewu yatsopano ndi yakale. Geogrid yachitsulo-pulasitiki ili ndi mphamvu yolimba, yoyikidwa pakati pa misewu yatsopano ndi yakale, imatha kukonza kukhazikika kwa misewu yatsopano ndi yakale, kuchepetsa kapena kuletsa ming'alu yomwe imachitika chifukwa cha kukhazikika kosagwirizana kwa misewu yatsopano ndi yakale, kupanga misewu yatsopano ndi yakale kupanga yonse, kuonetsetsa kuti misewu ya msewu ndi yokhazikika。
  • Kulumikizana kowonjezereka：Ikhoza kulumikiza bwino nthaka ya subgrade yatsopano ndi nthaka ya subgrade yakale, kuti subgrade yatsopano ndi yakale zigwirizane. Mwachitsanzo, pamene msewu wakale ukukulitsidwa, geogrid yachitsulo-pulasitiki imayikidwa pamlingo wolumikizira msewu watsopano ndi wakale, ndipo nthiti zake zazitali komanso zopingasa zimatha kutsekedwa mwamphamvu ndi nthaka mbali zonse ziwiri, kuti ziwongolere mphamvu yonse yonyamulira ndi kukhazikika kwa msewu watsopano ndi wakale, ndikuletsa mavuto monga ming'alu kapena kugwa panthawi yogwiritsidwa ntchito pambuyo pake。
• Kukulitsa gawo la subgrade reinforcement
  • Mphamvu yokongoletsa tsitsi：Pa nthaka yotambasuka, geogrid yachitsulo-pulasitiki imatha kukulitsa mphamvu yodula nthaka yodula. Pamene nthaka yoduladula ikuyendetsedwa ndi mphamvu zopingasa monga kuyendetsa galimoto, grille imatha kukana mphamvu yoduladula iyi ndikuletsa kulephera kwa nthaka yoduladula. Mwachitsanzo, m'mapulojekiti okulitsa misewu, kuyika geogrid yachitsulo-pulasitiki mu subgrade yotambasuka kungathandize kwambiri kukana kwa subgrade ndikuwonetsetsa kuti kapangidwe ka subgrade yoduladula kakhale kotetezeka komanso kokhazikika。
  • Kupewa kusamuka kwa mbaliChifukwa cha kugwira ntchito bwino kwa geogrid yachitsulo-pulasitiki, imatha kuletsa bwino kusintha kwa mbali ya subgrade fill. Pakumanga subgrade yokulirapo, nthaka yodzaza ikhoza kusunthidwa kupita kunja chifukwa cha kulemera kwake ndi katundu wakunja. Geogrid yachitsulo-pulasitiki imatha kupereka choletsa cha mbali, kusunga mawonekedwe ndi kukula kwa subgrade, ndikupewa kugwa kwa subgrade slope.
