Freeway Roadbed Solidification

Dothi bata kachitidwe mosavuta akuyendera freeway roadbed solidification. Kutengera kulimba kwa msewu wa msewu wa Hu-Hangzhou Expressway mwachitsanzo, njira yokhazikitsira nthaka yathandiza kwambiri. Malo omwe amadutsa pa Hu-Hang Expressway nthawi zambiri amakhala matope ndi minda, ndipo ali mumikhalidwe yomizidwa kwanthawi yayitali m'madzi. Ambiri mwa dothi lofewa ndi dothi logwirizana lomwe lili ndi mphamvu zochepa kwambiri zonyamula katundu, choncho kumanga mwachindunji sikungapangidwe pamtunda. Dothi losazama liyenera kulimba poyamba kuti ntchito yomanga ipite patsogolo.

Yichen anapereka 2 seti ya machitidwe okhazikika nthaka ndi okwana 4 zosakaniza mphamvu, ndi okwana kumanga voliyumu pafupifupi 500,000 kiyubiki mita ndi kuchiritsa kuya 3 mamita. Chigawo chapansi chochiritsidwa ndi dongosolo lokhazikika la nthaka ndi chokhazikika komanso cholimba ndi mphamvu inayake yonyamula katundu, yomwe ingatsimikizire kuti makina olemera amalowa m'malo omanga popanda chiopsezo cha subsidence. Nthawi yolimba ya dongosolo lokhazikika la nthaka ndi yofupikirapo kuposa yanthawi zonse kugwetsa ndi kudzaza miyala, komwe kumatha kuchepetsa mtengo waukadaulo. Ndipo amatembenuza mwachindunji zinyalala zofewa za nthaka kukhala chuma, zimapulumutsa chuma chamwala chophwanyika, zimagwirizana ndi lingaliro lachitukuko chokhazikika, ndipo ndi njira yomanga yobiriwira.
