Underground diaphragm wall construction method capable of ensuring grooving perpendicularity
The invention discloses an underground diaphragm wall construction method capable of ensuring grooving perpendicularity, and relates to the technical field of diaphragm wall construction. The underground diaphragm wall construction method capable of ensuring the grooving perpendicularity comprises the steps that a guide wall is constructed, and diagonal bracings are arranged in a guide wall ditchof the guide wall; grooving construction is carried out on the basis of the sequence of digging a single hole first and then digging a partition wall, the length of the partition wall is smaller thanthat of an open grab bucket, and in the grooving construction process, the specific gravity of mud is not smaller than 1.10; after it is determined that grooving is completed, slurry replacement is conducted; a reinforcement cage is hoisted, a guide pipe is placed and the concrete is poured. According to the underground diaphragm wall construction method capable of ensuring the grooving perpendicularity, the grooving perpendicularity is guaranteed, and moreover, slurry can more effectively protect the wall in the grooving process, and the influence of construction of the underground diaphragmwall on adjacent pipelines can be reduced. In addition, the problem that the guide wall is prone to generating displacement is solved.
本发明公开了确保成槽垂直度的地下连续墙施工的方法，涉及连续墙施工技术领域。该方法包括：构筑导墙，并且在导墙的导墙沟内设置对撑；基于先挖单孔后挖隔墙的顺序进行成槽施工，隔墙的长度小于抓斗开斗的长度，其中在成槽施工的过程中，泥浆比重不少于1.10；确定成槽完成后，进行泥浆置换；吊放钢筋笼，放置导管，以及进行混凝土浇灌。该方法保证成槽垂直度，并且可使得成槽过程中泥浆更加有效护壁，可减小地下连续墙的施工对临近管线的影响。以及，解决了导墙容易产生位移的问题。
