通过QC小组活动提高大跨度网架空心焊接球加工验收合格率的应用研究

在雅安市雨城区某会展中心项目施工过程中,为提高大跨度钢网架空心焊接球加工验收合格率,项目部成立了QC活动小组,以“5W1H分析法”为基础开展调研活动。小组成员通过现场调查、原因分析、对比试验对施工现场大跨度钢网架空心焊接球加工质量情况进行调查,成功找出制约加工质量的主要原因并针对性地制定了具体的实施对策,通过改进成型工艺、优化焊缝坡口形状和角度等措施,显著提高了钢网架空心焊接球加工一次验收合格率。此次研究为笔者公司带来了质量、社会、经济等方面的多重价值,并获得了业主、监理、设计各方的一致好评,可为类似项目施工提供参考。     

Leaching potential and changes in components of metals in two acidic ferrisols

Two acidic ferrisols, i.e., red soil （RS） and yellow red soil （YRS）, from the vicinity regions of non-ferrous ores in Hunan province of China, were leached with simulated acid rain through artificial column experiments. The results show that the total leaching mass of metals are m（Zn）〉m（Cu）〉m（Cd） from the original soils and m（Cd）〉m（Zn）〉〉 m（Cu） from the contaminated soils with external metals after leaching for 60 d continuously, leaching quantities of Cd and Zn from the contaminated red soil （CRS） are more than that from the contaminated yellow red soil （CYRS）, but for Cu, it is almost the same. The preferential fractions for leaching are mainly in exchangeable forms, and content of exchangeable forms decreases significantly in the contaminated soil profiles. The unstable fractions of Cd, Cu and Zn in the RS and YRS increase significantly with the decrease of pH value of simulated acid rain. Changes of fi, actions of external Cd, Cu, and Zn in the residual CRS and CYRS profiles are significantly affected by the acidity of acid rain, too. After leaching for 60 d continuously, Cd exists mostly in exchangeable form, Cu exists mainly in exchangeable, manganese oxide-occluded and organically bounding forms, and Zn exists in residual in CRS and CYRS profiles. Most of exchangeable Cd and Zn exist only small in surface layer （0-20 cm） and are transferred to the sub-layers, contrarily, Cu accumulates mostly in the topsoil （0-20 cm） with low translocation.
