Abstract:Taking foundation pit engineering in Shanghai as the background, measures to deal with the obstacle pile encountered during the construction of groove of diaphragm wall were analyzed. The method classification, equipment selection and technical countermeasures for the removal of obstacle piles in the development of underground space were studied. In addition, according to the construction process recording and pile removal effect of the groove of diaphragm wall, the preparatory work before the clearance was summarized and the four key construction points of “spin, cut, catch, pull” in application of the high pressure mud punching and pulling pile method were summarized.
Keywords:foundation pit engineering; obstacle pile; groove of diaphragm wall; pile removal
