基于工程实践的接头箱被埋后处理措施研究

Study on Disposal Measures of Buried Joint Box Based on Engineering Practice

摘要:

地下连续墙接头箱被广泛应用在地下连续墙施工，接头箱被埋事故时有发生。根据实际项目工程实践，对接头箱被埋原因进行综合分析，总结出包括技术、施工环境两类原因。提出接头箱被埋后的三种处理措施，分别为吊车顶拔、油顶配合吊车顶拔以及侧向剥离。并基于某水厂扩建工程接头箱被埋事故，给出该事故原因分析、实际处理措施以及处理结果，最后提出部分施工建议，以期为相关事故提供有效解决方法。

Abstract:

The joint box of underground diaphragm wall is widely used in the construction of underground diaphragm wall. Accidents occur when the joint box is buried on occasion. Based on the engineering practice of the actual projects, the causes of the buried joint box are comprehensively analyzed. Two causes including the technology and construction environment are summarized. Several disposal measures for the buried joint box are proposed respectively three kinds of crane topping pulling, oil topping with crane topping pulling and lateral stripping. Based on the accident of the buried joint box in a waterworks extension project, the cause analysis, practical disposal measures and disposal results of the accident are given. Finally, some construction suggestions are put forward in order to provide the effective solutions for the relative accidents.
