The utility model is exactly that shaped steel is inserted into the soil body after three axes agitating pile completes soil shear failure, is used in combination steel case will
Adjacent shaped steel carries out position and fixes, and ensures that the movement of position will not occur for shaped steel, adjacent steel case carries out position with locating steel frame
It is fixed, ensure that the position of steel case will not shift.
Preferably, the cross section of steel case is H-shaped, steel case includes riser, 2 pieces respectively with riser stringer board connected vertically and
Bottom plate, bottom plate respectively with riser and 2 pieces of stringer board vertical connections.
Preferably, riser top is equipped with the circular through hole for lifting by crane the steel case.
Preferably, 2 position limiting structures are located at bottom plate lower surface left end and right end, the position limiting structure includes 2 pieces
Be relatively fixed plate, and 2 pieces of fixed plates are each perpendicular to bottom plate and are welded to connect with bottom plate.
Preferably, the i shaped steel include 2 blocks of wing plates and web, web respectively with 2 pieces of wing plate vertical connections；Web
Between 2 fixed plates, web is detachably connected with 2 fixed plates；The upper end of 2 wing plates is equipped with for installing reinforcing bar
2 through-holes.
Preferably, locating steel frame is H-shaped, locating steel frame includes that a cross bar and 2 vertical with cross bar both ends respectively connect
The montant connect；2 montants are inserted into respectively in adjacent steel case.
Therefore, the utility model has the advantages that：
When design requirement shaped steel top is located at terrace or less, shaped steel is inserted into structure described in the utility model, it is fixed
The position of shaped steel can effectively prevent the movement of shaped steel；The locating steel frame of adjacent steel case can effectively fix the position of steel case, avoid by
In the displacement that the stream plasticity of silt soil generates, avoid causing serious quality accident.
