Zomangamanga zikuluzikulu kusanganikirana chomera wanzeru chitukuko chobiriwira chatsopano cholozera kusakaniza kwa fakitale yopanga mwachindunji

Njira yatsopano yanzeru komanso yobiriwira yopanga zida zazomera zazikulu zosakaniza. Polimbana ndi kusintha kwazomwe zikuchitika pakadali pano, fakitale yosakanikirana yayikulu ikukumana ndi zosintha zofanana. Masiku ano, ndikulimbikitsa kwakumanga kwamatauni ndi akumidzi, kufunika kwa makina a konkire kwawonjezekanso. Komabe, pali zida za konkriti zosatha pamsika, ndipo mtundu wawo ndiwofanana kwambiri. Mwa izi, pali zinthu zina zomwe zili ndi mtundu winawake wamagetsi, kulondola kwambiri, kulemera kwabwino kwa station station, komanso ndalama zochepa. Koma nthawi yomweyo, palinso opanga ena omwe amakopa ogula ndi mitengo yotsika, ndipo magawo aukadaulo azida akhala pamiyeso.

Choyamba, potengera kulondola kwa zida. Kulinganizika kwa zida zazikulu zosakanikirana ndizowonekera makamaka pazinthu zinayi za akaphatikiza, simenti, kusakanikirana ndi madzi. Kwa magulu, kulondola kumayang'aniridwa pafupifupi 2%, simenti ndi pafupifupi 1%, ma admixtures amakhala pafupifupi 1%, ndipo kulondola kwake ndi 1%. Pazigawo zonse, masikelo opimira masikelo ndi sikelo ya lamba nthawi zambiri amagwiritsidwa ntchito poyeza. Masikelo a m'Galimoto nthawi zambiri amakhala owerengera, ndipo ma hopper amayeza amagawika m'magulu owerengera komanso owerengera. Kulemera kwa simenti ndi ufa wina kumagawidwanso m'njira ziwiri: kulemera kwake payekha komanso kowonjezera. Zowonjezera zidagawika m'njira zitatu zoyezera: volumetric, misa, ndi kugunda malinga ndi zowonjezera zina. Za madzi, imagawidwanso m'magulu awiri a metering, omwe ndi volumetric komanso masekeli. Kuwonetsetsa kuti zopangira ndizolondola ndichofunikira popanga konkire yabwino kwambiri yamalonda. Ngati kulondola kwa zida kwasintha, zida mosakayikira zidzakhala zamphamvu kwambiri.

Kachiwiri, pazomera zazikulu zosakaniza, cholinga chachikulu ndikupanga konkire yabwino kwambiri yamalonda. Chifukwa chake, kusankha kwa zopangira ndikofunikanso makamaka. Ndikofunikira kwambiri pazida zobiriwira, kusankha kwa zida zopangira zakhudzidwanso. Malinga ndi zowonjezera, zotsalira zazinyalala zamakampani monga ntchentche phulusa, slag, slag yamadzi, ndi slag ya carbide slag iyenera kugwiritsidwa ntchito m'malo mwa kugwiritsanso ntchito kwa mphero zachikhalidwe zapadera zosalala. Chachiwiri, potengera magulu, mafakitale okhudzana nawo atha kugwiritsidwanso ntchito kuti agwiritse ntchito zinthu moyenera ndikukwaniritsa cholinga choteteza zachilengedwe.

Kuphatikiza apo, kuyang'anira zida zazomera zazikulu zosakanikirana kuyenera kukonzedwanso kuti tikwaniritse luntha lathu ndikutulutsa mphamvu pantchito. Ndikukula kwa nthawi, zida zodziwikiratu sizingapeweke. Ngati mukufuna kukhala ndi makina opanga konkriti, umunthu ndi luntha la zowongolera ndizofunikira.
