RESEARCH ON SAFETY OF EXCAVATION CONSTRUCTION OF DEEP FOUNDATION PIT STRUCTURES IN ADJACENT BUILDINGS
At present,the safety construction of anchor rod overlap in the excavation of deep foundation pits for adjacent tall buildings is fixed-point correlation,with low overlap efficiency,resulting in a decrease in the bear-ing optimization ratio.Therefore,it is proposed to design and research the safety construction technology for deep foundation pit excavation of adjacent existing buildings.Based on the current construction requirements,conduct on-site investigation and measurement and layout,excavate the soil at the preset position,adopt a multi structure mode to improve the overlap efficiency,overlap the multi structure anchor rod support structure,carry out queuing and precipitation treatment,and finally inspect and monitor the completion of construction.The test results show that the bearing optimization ratio of deep foundation pits is above 6.5,indicating that the current designed safety con-struction technology for deep foundation pit excavation adjacent to existing buildings is more stable and efficient.
