Reinforcing device for coastal soft soil texture ultra-large deep foundation pit supporting and supporting method
The invention relates to the technical field of supporting and reinforcing of soft soil foundation pits, in particular to a reinforcing device for supporting of a coastal soft soil texture ultra-large deep foundation pit and a supporting method.The double-layer grating assembly comprises a rear grating and a front grating which are distributed in parallel, and an inserting column is connected between the rear grating and the front grating in a telescopic and inserted mode; the three-shaft mixing pile has the beneficial effects that the side plate is installed on one side of an existing three-shaft mixing pile, a foundation is soft and is connected with the side plate in an inserted mode in the mixing process, and meanwhile the grating assembly is installed on the side close to a three-shaft mixing pile waterproof curtain in an inserted connection and extrusion mode; the grating assembly forms a vertically-distributed concrete reinforcing wall through high-pressure guniting during resetting, connection with the waterproof curtain is formed, effective lateral supporting plate reinforcing on the waterproof curtain is formed, the stability of the structure is greatly improved, and the requirements for the density and depth of follow-up pipe piles are reduced.
本发明涉及软土基坑的支护加固技术领域，具体为一种沿海软土地质超大深基坑支护用加固装置及支护方法，双层格栅组件包括一对平行分布的后格栅和前格栅，后格栅和前格栅之间伸缩插接有插柱，挤压插板的一端固定在液压机的伸缩杆上，有益效果为：通过在现有的三轴搅拌桩的一侧安装侧板，利用搅拌过程使得地基松软并于侧板的插接，同时利用插接挤压的方式将格栅组件安装在靠近三轴搅拌桩止水帷幕的一侧，利用复位时的高压喷浆使得格栅组件形成竖直分布的混凝土加固墙，且形成与止水帷幕的连接，形成对止水帷幕的有效侧向支撑板加固，大大提高了结构的稳定性，降低了对后续管桩密度和深度的要求。
