Description
Technical field
The present invention relates to construction technology of cast-in-place bored field, in particular to a kind of removing cast-in-situ bored pile casing inner wall mud
The device and its application method of slurry.
Background technique
Cast-in-situ bored pile is common substructure form in science of bridge building, before drilling that certain wall thickness is (general
Greater than 10mm) steel pile casting squeeze into supporting course.Exterior sheathing, bearing platform construction when steel pile casting is both pile foundation concreting face
When fixed point or pile foundation durability addition thereto, but determine steel pile casting wall thickness is usually to squeeze into the construction of supporting course to want
It asks.The often soft layers such as soil or muck soil, the pore forming process that can be constructed with churning driven be easy to cause mud to attach to
Steel pile casting inner wall, borehole cleaning process are difficult to thoroughly remove the mud of steel pile casting inner wall attachment.The presence of mud layer greatly reduces stake
Cohesive force and steel pile casting between base concrete and steel pile casting to the restraining force of pile foundation concrete, do not send out by so thick steel pile casting
Wave its due effect.Steel pile casting is generally used for pile foundation top, and the stress at this is more complicated, if considering steel pile casting to concrete
Hoop constraint power, then the reducible pile foundation ratio of reinforcement, reduce Pile Diameter, not only taken full advantage of the mechanical property of steel pile casting but also
Save engineering material.
Steel pile casting is improved to the hoop constraint power of pile foundation, it is necessary to assure steel pile casting inner wall is combined closely with concrete, nothing
The weak intercalated layers such as mud, but there has been no the devices and construction technical requirement of removing cast-in-situ bored pile steel pile casting inner wall mud at present.
