Kugwiritsa ntchito geogrid ya ulusi wagalasi mu projekiti yomanganso misewu yakale mumzinda

Fiberglass geogrid ndi chinthu chopangidwa ndi geosynthetic chomwe chimagwira ntchito bwino kwambiri, chomwe chagwiritsidwa ntchito kwambiri m'mapulojekiti akale omanganso misewu m'mizinda chifukwa cha mawonekedwe ake apadera komanso mankhwala. Zotsatirazi ndi kufotokozedwa mwatsatanetsatane kwa momwe chimagwiritsidwira ntchito.

1. Katundu wa Zinthu

Zipangizo zazikulu zopangira ulusi wagalasi ndi ulusi wagalasi wopanda alkali komanso wopindika, womwe umapangidwa kukhala gawo la maukonde kudzera mu njira yoluka yopingasa yapadziko lonse lapansi, kenako nkupaka pamwamba kuti upange chinthu cholimba pang'ono. Uli ndi mphamvu yolimba kwambiri komanso wotalikira pang'ono mbali zonse ziwiri za kupingasa ndi weft, ndipo uli ndi zinthu zabwino kwambiri monga kukana kutentha kwambiri, kukana kutentha pang'ono, kukana ukalamba komanso kukana dzimbiri.

2. Zochitika zogwiritsira ntchito

Fiberglass geogrid ili ndi njira zosiyanasiyana zogwiritsira ntchito pomanganso misewu yakale ya m'mizinda, makamaka kuphatikizapo zinthu zotsatirazi:

2.1 Kulimbitsa miyala

Pokonzanso msewu wakale wa konkire wa simenti, geogrid ya ulusi wagalasi imatha kukulitsa mphamvu ya kapangidwe ka msewu ndikuwonjezera magwiridwe antchito onse. Itha kuchepetsa ming'alu yowunikira, chifukwa geogrid ya ulusi wagalasi imatha kusamutsa katundu mofanana ndikusintha kupsinjika kwa ming'alu yowunikira kuchokera mbali yoyima kupita mbali yopingasa, motero kuchepetsa kupsinjika kwa phula lophimba.

2.2 Kulimbitsa misewu yakale

Pa msewu wakale, fiberglass geogrid imatha kukhala yolimbitsa. Imatha kulimbitsa maziko a nthaka yofewa komanso yofewa, kukweza mphamvu yonse yonyamula katundu wa msewu ndikuwonjezera nthawi yogwira ntchito ya msewu.

2.3 Kupewa ndi kuwongolera ming'alu yowunikira

Pambuyo poti msewu wakale wa simenti wapangidwa ndi konkire ya phula, ming'alu yowunikira imawonekera mosavuta. Kuyika kwa ulusi wagalasi kumatha kuletsa kapena kuchepetsa ming'alu yowunikira ya msewu woyamba wa phula, chifukwa uli ndi mphamvu yolimba komanso kutalika kochepa, ndipo ukhoza kusintha kuti ugwirizane ndi kusintha kwa msewu.

3. Njira yomanga

Njira yoyika fiberglass geogrid nthawi zambiri imaphatikizapo izi:

3.1 Kuyeretsa malo ozungulira

Musanayike fiberglass geogrid, gawo loyambira liyenera kutsukidwa kuti liwonetsetse kuti ndi loyera komanso lathyathyathya, lopanda zinyalala ndi mafuta.

3.2 Kuyika grille

Ikani fiberglass geogrid pa maziko ake malinga ndi zofunikira pa kapangidwe kake, kuonetsetsa kuti ndi yosalala komanso yopanda makwinya.

3.3 Grille yokhazikika

Gwiritsani ntchito misomali kapena zotetezera zapadera kuti muteteze grille ku gawo loyambira, kuti isasunthike panthawi yomanga.

3.4 Kukonza phula

Ikani chisakanizo cha phula pa grille ndikuchilimbitsa kuti chikhale cholimba. Mwanjira imeneyi, fiberglass geogrid imayikidwa bwino mu kapangidwe ka msewu.

4. Zolemba

Mukamagwiritsa ntchito fiberglass geogrid pokonzanso misewu yakale ya m'mizinda, muyenera kulabadira mfundo zotsatirazi:

4.1 Kusankha zinthu

Sankhani malo odalirika a fiberglass geogrid kuti muwonetsetse kuti zizindikiro zake zogwirira ntchito zikukwaniritsa zofunikira zaukadaulo.

4.2 Ubwino wa zomangamanga

Pa nthawi yomanga, khalidwe la zomangamanga liyenera kulamulidwa mosamala kuti zitsimikizire kuti grille yayikidwa bwino komanso yokhazikika kuti ipewe makwinya ndi mabowo.

4.3 Kuteteza Chilengedwe

Samalani ndi kuteteza chilengedwe panthawi yomanga kuti mupewe kuipitsa chilengedwe chozungulira.

Mwachidule, fiberglass geogrid ili ndi phindu lofunika kwambiri pa ntchito zomanganso misewu yakale m'mizinda. Sikuti imangowonjezera mphamvu ya kapangidwe ka msewu ndikuwongolera magwiridwe antchito onse, komanso imaletsa ming'alu yowunikira ndikuwonjezera nthawi yogwirira ntchito misewu. Pa nthawi yomanga, chisamaliro chiyenera kuperekedwa ku nkhani monga kusankha zinthu, mtundu wa zomangamanga ndi kuteteza chilengedwe kuti zitsimikizire mtundu ndi zotsatira za polojekitiyi.
