Abstract
The invention discloses an isolating device for impact holing drilled slurry. In the construction process of impact drilling, a round steel plate is arranged beyond the range for a hole bottom impact bit to move to drilled holes; slurry with higher viscidity and density is held in a hole in the upper part of the steel plate, and the slurry is capable of effectively protecting the wall of the hole, and preventing the wall of the hole from collapsing; slurry with lower viscidity and density is held in a hole in the lower part of the steel plate, and when impact holing is performed on the hole in the lower part of the steel plate by the bit, slurry resistance can be reduced, and the impact holing efficiency is increased.
Description
Technical field
The present invention relates to Geotechnical Engineering field, particularly relate to a kind of impact holing drilling slurry spacer assembly.
Background technology
Along with the fast development of China's transport development, most of highway construction is carried out in western mountainous areas.Carry out highway construction in mountain area, bridge occupies significant proportion, when constructing to bridge pier, many times adopts impact holing mode to construct to pile foundation of bridge pier.When adopting impact holing mode to construct, in order to keep hole wall to stablize, preventing hole wall collapse, generally all adopting the method for mud off to carry out.Now along with the continuous expansion of bridge scale, the pile foundation of bridge pier is more and more darker.In impact holing process; in order to protect the stability of hole wall; viscosity and the severe of mud are increasing, although protect the stability of hole wall in work progress, because the viscosity of mud increases; the viscous drag when drilling hole burst of drill bit increases; in order to overcome the viscous drag of mud, the impact energy of drill bit consumes in mud greatly, causes fractured rock efficiency at the bottom of hole not high; rate of penetration is slow, and pore-forming efficiency is extremely low.
Summary of the invention
In view of this, the invention provides a kind of impact holing drilling slurry spacer assembly, solve the drill bit problem that resistance is excessive in mud when impact holing, thus drilling efficiency when improving impact holing.
A kind of impact holing drilling slurry spacer assembly, comprises steel plate, inlet pipe, residue outlet, wire rope and wire rope and lays mechanism, wherein:
Described steel plate is disc, and its diameter is less than bore diameter, and steel plate circle centre position arranges lacing hole, and the card of steel plate is provided with the slag notch relative to center of circle symmetry and stock inlet; 3 wire rope tie points are circumferentially evenly provided with at described steel plate edge;
Described wire rope lays mechanism 3, is evenly fixed on boring edge; Three wire rope tie points of steel plate fix three wire rope one end respectively, and the wire rope other end is connected to wire rope and lays in mechanism; The wire rope of drill bit described in crane hanging component passes from described lacing hole, and steel plate is lifted above drill bit in the borehole by wire rope level; The stock inlet of described steel plate connects described inlet pipe, and described slag notch connects described residue outlet; The free end of described inlet pipe and slag notch is arranged on the edge of boring, and wherein, the free end of inlet pipe is pumped to clear water, and the free end of slag notch arranges the electrodynamic pump of slurry-sucking.
Preferably, the diameter of described steel plate 20cm less of bore diameter; The thickness of described steel plate is 5mm ~ 10mm; The diameter of described lacing hole is 10cm; The diameter of described slag notch and stock inlet is 20cm; Described slag notch center and mud mouth center and steel plate 1 Edge Distance are 30cm; Described wire rope tie point is apart from steel plate edge 20cm.
The present invention has following beneficial effect:
Spacer assembly of the present invention, in impact holing work progress, more than drill hammer scope of activities at the bottom of hole spacing hole; one circular steel plate is set; be the mud that viscosity ratio is comparatively large and density is larger in the hole on steel plate top, effectively can protect hole wall, control hole wall collapse.And in the hole of steel plate bottom, be the mud that viscosity and density are less, in the hole of drill bit steel plate bottom again during impact holing, can slurry resistance be reduced, put forward impact holing efficiency.

Detailed description of the invention
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
Below in conjunction with drawings and Examples, the present invention is described in further detail.
When mud viscosity and density affect the percussion drilling efficiency of drill bit comparatively greatly in holing, first the lacing hole 10 connected on drill hammer steel wire penetrating steel plate, connect drill hammer and drill bit is put into hole.Again on steel plate 1 coupling together with wire rope tie point 7 wire rope 4 with fixation steel plate on steel plate, residue outlet 2 and steel plate are exported 8 and are connected and are tightly connected and locate, inlet pipe 3 and steel plate are entered mud mouth 9 and is connected and is tightly connected and locate.Then by wire rope 4, steel plate being put into precalculated position, hole, resistance when putting into reduce, steel plate 1 certain angle that tilts can be put into.After precalculated position put into by steel plate 1, pump into clear water to inlet pipe 3 upper end, extracted out by the mud in boring by residue outlet 2, so, the mud of steel plate less than 1 is replaced by the clear water that inlet pipe 3 pumps into, and changes viscosity and the density of mud in steel plate 1 bottom hole.Like this, the mud on steel plate 1 top owing to keeping larger viscosity and density, thus keeps the stable of hole wall, and viscosity and the density of the mud of steel plate 1 bottom are less, reduce the resistance of motion of drill hammer 12, improve drilling efficiency.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
