40米跨箱梁滿堂支架施工方案范文(文件)
【正文】 澆梁段頂板上，通過人孔、型鋼和鋼絲繩等將卷揚(yáng)機(jī)固定。故在張拉完成之前模板能夠全部行走到位后。 ?、芗?xì)骨料：江西贛江產(chǎn)中粗砂。 箱梁混凝土澆筑 由于砼為整跨澆注，方量較大，澆注時間長，首跨澆注方量為408m3，標(biāo)準(zhǔn)跨每跨澆注方量為340m3。②砼初凝時間過短。頂板砼表面出現(xiàn)裂紋是由以下一種或幾種原因引起①澆注氣溫過高或風(fēng)干現(xiàn)象嚴(yán)重造成砼表面容易開裂。箱梁內(nèi)翻漿現(xiàn)象嚴(yán)重是由以下一種或幾種原因引起①砼坍落度過大。⑤砼澆注時氣溫偏低或雨天澆注。每一跨砼澆注時間為13小時左右，采用本方法澆注的砼，拆模后，外觀質(zhì)量較好，沒有出現(xiàn)分層和冷縫現(xiàn)象，砼頂面沒有出現(xiàn)裂紋。如果采用水箱加水法進(jìn)行預(yù)壓，建議在水箱底部設(shè)計若干滾輪或滾軸，以便2~3人就能推動水箱前移。如果采用大型鋼模板，建議在模板下方橫向工字鋼上設(shè)置滾輪，采用人工推動模板前移。 Four, the pledgor, mortgagor due to special reasons not to sign the contract, may authorize others to sign the contract and retained after the notary notarized power of Attorney (parties abroad, outside the territory of China sent or delivered by a power of attorney shall be certified by the notary public of the country, and certified by the Embassy or Consulate in the country).
