砼缺陷處理施工作業(yè)指導(dǎo)書
三峽永久船閘地下輸水系統(tǒng)砼表面質(zhì)量要求高,缺陷處理工藝要求高。為使缺陷處理工作做到程序化和規(guī)范化,以確保缺陷處理質(zhì)量,特編寫《永久船閘地下輸水系統(tǒng)砼缺陷處理施工作業(yè)指導(dǎo)書》,用于指導(dǎo)缺陷處理施工作業(yè)。本作業(yè)規(guī)程是結(jié)合永久船閘地下輸水系統(tǒng)砼缺陷的特點(diǎn),依據(jù)《三峽一、二期工程主體建筑物砼表面缺陷處理技術(shù)要求(試行)》及缺陷處理相關(guān)設(shè)計文件編制而成。
1缺陷類型
永久船閘地下輸水隧洞砼質(zhì)量缺陷分為五個類型:溫度裂縫,層面縫滲水;結(jié)構(gòu)縫滲水;砼點(diǎn)面滲及砼表面缺陷
Concrete Defects Construction work instructions
Three Gorges ship lock concrete underground water systems that require high surface quality, defect handling process demanding. In order to achieve defect handling procedures and standardized to ensure quality defect treatment, especially the preparation of "permanent lock underground distribution system Concrete Defects Construction work instructions" to guide the construction defect handling operations. This work order is a combination of permanent lock underground distribution system characteristics of concrete defects, according to "Three phase one and two of the main building concrete surface defect in the technical requirements (trial)" and Defects related design documents compiled.
One defect type
Permanent ship lock of Concrete Underground Tunnel defects into five types: temperature cracks, seam seepage level; structural joints in the water seepage; concrete surface infiltration point and the concrete surface defects
