邻近保护建筑物的地下连续墙槽壁加固工艺研究

Study on Reinforcement Technology for Slotted Wall of Underground Diaphragm Wall Adjacent to Protective Buildings

地下连续墙槽壁加固可起到有效的止水及土体加固作用,但其会对周边土体造成挤压及扰动,故不适用于周边存在保护建筑及重要地下管线区域。针对上海董家渡金融城工程项目中天主教堂的保护,探索合理的槽壁加固施工工艺,并围绕绿色环保、低扰动的原则进行研究,有效地保护了邻近建筑。

The reinforcement of the underground diaphragm wall can play an effective role in water stopping soil strengthening, however it will lead to compression and disturbance on the surrounding soil, so it is not suitable for the areas around with protective buildings and important underground pipeline. In view of the protection of the Catholic Church in Shanghai Dongjiadu financial city project, this paper explores a rational reinforcement technology for slotted wall of underground diaphragm wall and studies the principles of environmental protection and low disturbance to effectively protect adjacent buildings.
