Application of"Front Inclined and Back Straight"Inclined Pile Foundation Pit Support in Silt Geology
In order to improve the safety and reliability of foundation pit support system,this paper takes a residential building construction project as an example to study the application of"front inclined and back straight"inclined pile foundation pit support in silt geology,and its post-construction effect is monitored and evaluated.The results show that when the excavation to the bottom of the foundation pit,the maxi-mum deformation of the front inclined pile is 47 mm,and the maximum deformation of the back straight pile is 25 mm,and the increase of the maximum deformation with the passing of time is small.The maximum displacement of the front inclined pile and the back straight pile does not exceed the design requirements under all working conditions,and has a good support application effect.
