Description
Technical field
The utility model design one revolve dig standby, be specifically related to a kind of subgrade mud protection churning driven.
Background technology
For subgrade earth formation; collapse hole phenomenon is easily there is in boring procedure; existing brill digs standby; its drill bit structure goes out earth material drill bit for helically foliaceous is equilateral; dig in process at brill; the relative motion of material to hole wall is dug out owing to boring for a long time; cause drilling quality low; mud diaphragm lost efficacy; easily there is collapse hole; and comparatively common landform is for the ununified pumping treatment system of mud system, in pumping procedure, easily there is the phenomenon that native slag is non-rising, cannot clear up native slag in time.
Utility model content
The purpose of this utility model is for above-mentioned Problems existing and deficiency, provides a kind of reasonable in design, and construction effect is good, the subgrade mud protection churning driven that slag discharge efficiency is high.
For achieving the above object, the technical scheme taked is:
A kind of subgrade mud protection churning driven, comprises rotary drilling rig, steel pile casting and mud circulating system, described mud circulating system comprises the modified pond of the mud be arranged side by side, mud-settling pit, the agitator be connected with the modified pond of mud, be communicated with the modified pond of mud and the slurry pipeline in boring, be communicated with the mud veclamation pipe of mud-settling pit, with the slush pump be separately positioned on slurry pipeline and mud veclamation pipe, described rotary drilling rig comprises walking mechanism, hoisting mechanism, be arranged on the mast in walking mechanism, be arranged on the drill rod bracket on mast and unit head, mate the drilling rod be arranged in drill rod bracket and unit head, and drill bit, described mast top handing-over has guide strip and assembly pulley, is also provided with assembly pulley in the middle part of described drilling rod top and mast, and described drill bit is two telescoping structures, and it comprises inner sleeve, outer sleeve, be arranged on the junction plate between inner sleeve and outer sleeve, be arranged on the cross-shaped gripper shoe in inner sleeve, be positioned at the mouth that gathers materials of the structure that is centrosymmetric of inner sleeve and outer sleeve bottom, with the broken drill bit being arranged on mouthful periphery that gathers materials, described junction plate is multistage structure spaced apart.
Described steel pile casting length is 7 ~ 9m, and steel pile casting is to section welded construction.
Overfall pipeline and slurry recirculating pump is provided with between the modified pond of described mud and mud-settling pit.
Adopt technique scheme, acquired beneficial effect is:
The utility model reasonable in design, its mud pumping system can carry out rational modified mud for different landform, native slag can be floated slag tap, prevent the sticky glutinous reinforcing bar protecting wire net of mud simultaneously, avoid impacting building of later stage, in addition the drill bit that the application adopts is interior discharging drill bit, completely cuts off, substantially increase the quality of boring to the hole wall of boring.
