The utility model relates to a kind of bored
pile construction recyclable steel casing, belong to bored
pile construction technical field.The bored
pile construction recyclable steel casing, comprising: casing mechanism, casing mechanism includes casing body and support arc plate;Auxiliary mechanism, auxiliary mechanism includes upper limit arc plate, movable arc plate and
lower limit arc plate;Two groups of upper limit arc plate are positioned to movable arc plate, when needing to disassemble steel casing, movable arc plate is rotated, movable arc plate is rotated with soil layer separation with
small amplitude, and movable arc plate drives upper limit arc plate and
lower limit arc plate
small amplitude movement at this time, to drive upper limit arc plate and
lower limit arc plate with soil layer separation, and then steel casing is segmented with soil layer separation, avoid relying on hoisting directly to steel casing
whole body traction, leading to steel casing inner wall and soil layer friction is larger, to avoid steel casing deformation or
cracking, to ensure the subsequent recycling of steel casing use.
