—、小组概况二、选题理由(一)课题简介。本工程二沉池地下二、三层墙体底部为斜面,倾斜角度60度,长度共1008米。刮泥机设备设计斜面平整度偏差要求为5mm/2m,要求精度高。(二)选题理由。根据合同约定,二沉池混凝土墙体斜面平整度合格率高于92%。小组对工程现状进行了调查(见表1),确定此次活动的课题为“提高二沉池混凝土墙体斜面平整度合格率”。
-, Group Overview Second, the reasons for the topic (a) Introduction to the project. The second and third floor of the second floor of the sinking tank are inclined at the bottom, with a tilt angle of 60 degrees and a total length of 1008 meters. Scraper equipment design slope flatness deviation of 5mm / 2m, requiring high precision. (B) the reasons for the topic. According to the contract, the pass rate of the secondary settling tank concrete wall is higher than 92%. The team conducted a survey on the status quo of the project (see Table 1), and confirmed that the topic of the activity was “to improve the pass rate of slope smoothness of the secondary settling tank concrete wall”.
