摘 要:以地下连续墙施工中遇到的问题,对设计与施工提出合理化建议,包括增加导墙翼墙宽度,合理选用成槽机械,关注成槽平面位置控制,适当提高泥浆性能,严格控制成槽垂直度,加大成槽质量检验,统一沉渣测锤外型及质量,强调二清是必须工序,钢筋笼吊装理论与实践相结合,对比分析支撑体系受温度的影响等。通过地下连续墙施工工艺、施工设备、施工参数的调整及相关数据的统计,找出主要原因,明确控制要点,对后续施工有一定指导作用。This paper focuses on the problems encountered in the construction of underground diaphragm wall.Put forward reasonable suggestions for design and construction,increase the width of guide wall wing wall,reasonably select grooving machinery,pay attention to the control of grooving plane position,properly improve the slurry performance,strictly control the verticality of grooving,increase the quality inspection of grooving,unify the appearance and quality of sediment measuring hammer,emphasize that the second cleaning is a necessary process,combine the theory and practice of reinforcement cage hoisting,and compare and analyze the influence of temperature on the support system.Through the adjustment of construction technology,construction equipment and construction parameters of underground diaphragm wall and the statistics of relevant data,the main reasons are found out and the control points are clarified,which has a certain guiding role for the subsequent construction.
