DEEP FOUNDATION PIT SUPPORT TECHNOLOGY IN THE CENTRAL AREA OF THE CITY
The working condition of foundation pit supporting engineering located in the central area of city is often complex.Such as groundwater,surrounding structures,underground pipelines,peripheral roads,etc.,instable foundation pit leads to serious consequence.In order to ensure construction safety,cast-in-place piles in row supporting method is commonly used.Its advantages are high strength,stiffness,good stability,strong applicability.The integrity of the support system is further enhanced by internal support,waist beams,anchor bolts.For the places which require particularly small deformation,harsh construction conditions and strict limitation of the soil displacement,double row piles support is adopted.
