By setting several bearing plate and branch in deferent location of pile body,squeezed branch pile can improve bearing load capacity of single pile,shorten the pile length,lower cost of pile engineering.

To ascertain the feasibility and serviceability of the squeezed branch piles in Nanjing,authors have took in-site pile tests.

Combing construction of cast-in-situ pile with expanded branches and plates of Zhangzhou Sewage Treatment Plant,the author studies mechanism of action and bearing capacity behaviour in cast-in-situ pile with expanded branches and plates.

This article shows that the cast-in-situ pile with expanded branches and plates is more economical than other kinds of pile by introducing the design and application of cast-in-situ pile with expanded branches and plates in a certain engineering project.

This paper introduces the new technique-bored pile including extruded-expanded bored pile with multi-bearing trays,after-grouting technique for bored pile and bored complex pile,expounds the design thinking of pile foundation,and analyses the economic benefits.

With the example of the administrative building works in Cixi People s Hospital, the workmanship for construction of the in-situ concrete pile with extruded tray support is introduced hereby, and based on engineering practice, key points are summed up for monitoring the construction quality and tray formation.

Analysis on deformation characteristic of squeezed branch and plate pile under lateral load with finite element method;

The squeezed branch and plate pile is a type of special figure pile.
