Reverse construction method of raft foundation steel bars of deep foundation pit
The invention discloses a reverse construction method of raft foundation steel bars of a deep foundation pit. The deep foundation pit is divided into four reverse construction areas from outside to inside and from top to bottom. The reverse construction method comprises the following steps of feeding the reinforcing steel bars; constructing bottom bars in the first reverse construction area; constructing bottom bars in the second reverse construction area; carrying out surveying and setting out to control elevation; constructing steel bar support systems in the first reverse construction areaand the second reverse construction area; constructing face bars in the first reverse construction area; constructing face bars in the second reverse construction area; constructing bottom bars in thefourth reverse construction area; constructing bottom bars in the third reverse construction area; constructing a steel bar support system in the third reverse construction area; and constructing face bars in the third reverse construction area, and carrying out checking; According to the reverse construction method of the raft foundation steel bars of the deep foundation pit, the construction area is divided into the plurality of areas, raft foundation steel bar construction is carried out through a reverse method, and multi-procedure alternate construction is achieved; and the design safetycoefficient of frame bodies is improved by densifying the supporting frame bodies and reinforcing diagonal draw steel bars, workers are reasonably allocated, and field warning facilities are added, so that safe and efficient construction of the raft foundation steel bars of the deep foundation pit is achieved.
本发明公开了一种深基坑筏板基础钢筋逆做施工方法，深基坑按照由外往内、由上往下划分为四个逆做施工区域，包括以下步骤：钢筋下料；第一逆做区域底筋施工；第二逆做区域底筋施工；测量放线控制标高；第一逆做区域和第二逆做区域钢筋支架体系施工；第一逆做区域面筋施工；第二逆做区域底筋施工；第四逆做区域钢筋施工；第三逆做区域底筋施工；第三逆做区域钢筋支架体系施工；第三逆做区域面筋施工,验收；本发明通过对施工区域划分多个区域，采用逆做法进行筏板基础钢筋施工，实现多工序穿插施工；通过加密支撑架体和加强斜拉筋，提高架体设计安全系数，并合理配置工人、增加现场警示设施，实现深基坑筏板基础钢筋安全、高效施工。
