土建施工经验总结（Summary of civil construction experience）

土建施工经验总结（Summary of civil construction experience） The basic check slot or pile. Trough inspection (shallow foundation), will be accompanied by the staff survey together, and whether the field investigation report, if there is abnormal place, nature of the main observation bearing layer, such as we are in the area of shallow foundation No. 2 Hicks. The soil is hard, color Brown, also with some differentiation substances. In addition this 2 soil is thin, generally is 1~2 meters, so the site can be used 12 rib steel insert bearing layer, see after the removal of the soil and the depth in the steel stick to determine the thickness of the pile. (Zhuang Ji), which is mainly based on the bearing capacity of pile the calculation of pile machine tonnage, according to check soil geological report any abnormal (mainly through the pile pile up to judge), observe the last 1 meters used in degree, the pile up phenomenon is obvious, the current pile machine check. Especially a large cast-in-place pile head should be strictly controlled For the filling coefficient of cement mixing pile. Focuses on the control of the water cement ratio, cement content per meter. And the mixing times. Reinforcement foundation acceptance: As the focus of the course is to check the bar, including the reinforcement information is not comprehensive, the factory test report report entry Report According to the site \ \ distance location drawings check steel wire is not conform to the standard \ base size, the thickness of the protective layer welding, appearance quality inspection Ask the welded joint pull test report. Lap length, anchorage length. Nodes (primary and secondary beam junction, Liang Zhu junction) at most can manifest the reinforcement engineering quality The amount of the. The additional reinforced beam, such as beam hanger and floor hanger setting mode is the opposite. The steel bar at the lower end of the horizontal section length is fixed position. The stirrup settings are correct. The
