Construction method for protecting overpass structure around deep foundation pits
The invention discloses a construction method for protecting the overpass structure around deep foundation pits, which is intended for the overpass, and comprises the following steps of: constructing a envelop enclosure of long deep foundation pits close to the overpass; Reinforcing the bottom of the deep foundation pits; constructing isolation piles inside and outside the deep foundation pits within the bearing platform range of the overpass; establishing a deep foundation pits support system; Digging the long strip deep foundation pits; And carrying out structural construction on the long strip deep foundation pits. The method can effectively reduce the long side effect of the long strip foundation pit; It can effectively reduce the influence of heavy load around the foundation pits on the envelop enclosure and elevated pier; It can ensure no loss of supporting axial force and strengthen the supporting system; It can reduce the deformation data of foundation pits at the end of construction; It can effectively reduce the deformation of foundation pits envelop enclosure and the settlement of surrounding ground surface; Thereby the purpose of protecting the overpass is realized. i gr I
