A kind of profundal zone bored pile harmless mounting or dismounting clad steel casing group structure, described clad steel casing group comprises outside steel pile casting and inner side steel pile casting; Outside steel pile casting is rolled by steel plate and is welded, and its lower end inner wall welds a loop bracket, bracket is arranged a vertical baffle plate, arranges a rubber sheet gasket in bracket upper recess; Outside steel pile casting forms steel pile casting group by upper and lower three road steel trusss; Steel pile casting group upper end, outside arranges the temporary platform of construction steel platform as drilled pile construction on steel truss; Inner side steel pile casting is two lobe half rounds casings, inner side steel pile casting arranges multiple level to jack and multiple verticality monitor box along sidewall, lower end arranges a Vertical dimension jack, vertically interval arranges hinge, rubber pad groove and rubber pad, arranges closing device with relative hinge positions.
As preferably: described closing device, is made up of spring and slippage cylinder, wherein access hydraulic pressure in slippage cylinder interval forms folding jack.
The beneficial effects of the utility model are:
(1) stability of steel pile casting when adopting outside steel pile casting group can guarantee that building-in depth is limited when Riverbed is thinner, reduce difficulty and the cost of construction, upper end steel truss being laid steel plate can as temporary construction platform;
(2) inner side steel pile casting integrated system adopts two lobe half rounds casings, the folding of half rounds casing is controlled by level jack, closed during sinking, be separated when removing, the mounting or dismounting of convenient inner side steel pile casting, reduce the impact on pile concrete surface, improve pile body apparent mass;
(3) steel pile casting lower end, inner side is bearing in by rubber sheet gasket on the steel bracket of outside steel pile casting lower end inner wall, and the existence of rubber sheet gasket effectively prevent concrete slurry and enters space between the steel pile casting of medial and lateral;
(4) steel pile casting lower end, inner side arranges vertical jack, when occurring that the adhesion impact of steel pile casting lower end, inner side hangs out, can hang out inner side steel pile casting easily by applying a jacking force;
(5) inner side steel pile casting inwall arranges verticality monitor box, and in the steel pile casting sinking process of inner side, the verticality of Real-Time Monitoring steel pile casting and position, adjusted automatically by level jackization.
