建筑深基坑施工中土钉墙结合管井降水技术的应用

Application of Soil Nailing Wall Combined With Pipe Well Dewatering Technology in Construction of Deep Foundation Pit

深基坑工程影响着项目的稳定性和安全性,若要达到最佳的施工效果,则需要科学选择支护技术,避免水对土体造成负面影响。文章以深基坑施工作为研究的切入点,从工程实例角度对搅拌桩和锚钉墙支护下管井降水施工设备和设施进行了详细分析,从止水惟幕、降水等不同维度提取了技术施工要点。

Deep foundation pit engineering affects the stability and safety of the project.In order to achieve the best construction effect,it is necessary to scientifically select the support technology to avoid the negative impact of water on the soil.Taking the construction of deep foundation pit as the starting point of research,this paper analyzes in detail the construction equipment and facilities of pipe well dewatering supported by mixing pile and anchor wall from the perspective of engineering examples,and extracts the key points of technical construction from different dimensions such as waterproof curtain and dewatering.
