超 平地坪施工方案 超平地坪施工方案 Construction Scheme for Flat Floor 一、施工程序框圖與施工步驟 Construction procedure frame and construction scheme 1. 地坪標(biāo)高確認(rèn): Confirm floor elevation 。 Datum mark must be confirmed on site. ,對嚴(yán)重高低不平處進行處理。 Check subbase surface elevation before concrete cast work, and deal with the seriously rugged place. 2. 地坪模板確認(rèn) Confirm formwork Confirm elevation of the formwork. Confirm stability of the formwork. 3. 混凝土供應(yīng)及鋪筑 Cast Concrete : Concrete requirement: 混凝土標(biāo)號為 C30。 Concrete pressive strength: C30。 粗骨料最大粒徑不超過 25mm; Largest size of coarse aggregate : 25mm; 塌落度為 10cm177。 2; Slump: 10177。 2 cm; 含氣量在 177。 % 以內(nèi) Air content within 177。%。 同一施工現(xiàn)場應(yīng)使用同一公司的商品混凝土; Concrete must be supplied by the same pany on the same construction site。 混凝土泵車的運輸時間不應(yīng)超過 40 分鐘,攪拌車之間的時間間距不應(yīng)超過 10 分鐘; Transport time of concrete pumping truck should not exceed 40 minutes。 塌落度測試標(biāo)準(zhǔn),每 60m179。檢查對 1 臺泵車進行測試; Slump test must be carry out every 60m179。 concrete。 其他為注明事宜,根據(jù)乙方的配比; Others undertake according to party B’s concrete mix design. b. 鋪筑前擬定計劃,并審核; Make a scheme and certificate before concrete cast 混凝土鋪筑是影響混凝土品質(zhì)的主要環(huán)節(jié),因此必須事先擬定好計劃,并得到項目監(jiān)理的認(rèn)可; Concrete casting is the most important part through the entire construction process which can influence the quality of concrete directly, so a scheme must be wellprepared in advance and certificate by project monitor. 擬定混凝土鋪筑計劃時需考慮的事宜: Matters below must be taken into account when a concrete casting scheme is drafted: * 現(xiàn)場混凝土輸送通道及 設(shè)備進出的通道。 On site passages for concrete transport and equipments entrance. *日鋪筑面積; Casting areas per day. * 混凝土鋪筑量; Cas
