Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail. Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
Embodiment: a kind of cast-in-situ bored pile hole cleaning device, including drilling rod 1, described drilling rod being provided with at least one stirring paddle 2, described stirring paddle is made up of blade 3 and propeller hub 4, described propeller hub encloses hoop on described drilling rod, and described blade has at least two panels and blade face to be upwards fixed on described propeller hub.
Described propeller hub is made up of two lobes, and one end of two lobe propeller hubs is concave-convex type draw-in groove 5, and the other end is the butt strip 6 turned up in the axial direction, and the radian of two lobe propeller hubs is equal and less than 180 degree.
Stirring paddle is fixed on drilling rod by the hoop effect of enclosing of two panels propeller hub. After stacks, stirring paddle being inserted in drilling rod, stirring paddle can be multiple, needs to be arranged on drilling rod with a determining deviation according to construction, fastens again through the bolt on butt strip.
The internal diameter of described propeller hub is equal to the external diameter of described drilling rod, and two lobe propeller hub symmetries are set on described drilling rod, and one end of two lobe propeller hubs is connected by pin 7, and the other end is fastenedly connected by bolt 8.
Described blade is two panels and is symmetrically distributed on described propeller hub, and the blade face of described blade is oblique helicoid. Stirring paddle can be selected for two leaf oars, and oar body material is steel, and two panels blade is symmetrically distributed on propeller hub circumference, and blade blade face is upwards arranged, to ensure that blade upwards pushes mud, blade root is connected with propeller hub by welding; Propeller hub internal diameter can be equal to drilling rod external diameter, but the radian of two lobe propeller hubs is less than 180 degree, to ensure the space having fastening between two butt strips.
Described concave-convex type draw-in groove is provided with the perforation vertically docked for pin, and described butt strip is provided with the through hole fastened along circular arc tangential direction for bolt.
The primary structure of the present invention is stirring paddle, and stirring paddle is made up of blade, two lobe propeller hubs, fastening bolt, pin. Blade and propeller hub make by steel plate, and blade is by being fixedly welded on propeller hub. Two lobe propeller hub one end are connected by pin, and the other end is bolted connection.
Propeller hub internal diameter can be equal to drilling rod external diameter, but two lobe propeller hubs should be less than 180 degree, there to be certain pre-compact space between butt strip, the diameter that two panels blade is formed less than bit diameter, with prevent stirring paddle under pass through and journey be damaged or stake inwall is damaged by rotary course;Hole-drilling pile-filling machine GPS-15 frequently with drilling rod external diameter be 90mm, bit diameter is 800mm, blade in embodiment can use 0.3mm steel plate to make, propeller hub can use 0.5mm steel plate to make, propeller hub internal diameter is 90mm, blade tilts to be symmetrically welded on propeller hub, butt strip has two diameters more than 10mm to perforation, 10mm bolt fastens.
When holing stacks, stirring paddle is inserted in a certain position of drilling rod, blade blade face upwards and neighbouring stirring paddle horizontal direction vertical, stirring paddle, by together transferring with drilling rod after two pieces of bolts fastenings, operates according to this and installs stirring paddle with a determining deviation. When boring is to, when specifying absolute altitude, stopping drilling depth, slightly carry burr-drill and dally from 10cm��20cm at the bottom of hole, and keep mud normal circulation, lift effect by means of stirring paddle, accelerate the more mud of hole inner suspension boring mud and swap out speed.
This cast-in-situ bored pile hole cleaning device, including drilling rod and stirring paddle. During direct circulation revolution once clear hole, drilling rod drives the stirring paddle being fixed thereon to rotate, and coordinates the idle running of drill bit, effectively the sediment risen at the bottom of stake is upwards pushed step by step, what improve sediment carries efficiency, reduces sediment thickness, and then improves clear hole efficiency and bearing capacity of pile foundation; Meanwhile, stake bottom slurry concentration is higher, and hole wall is whitewashed effect by the mud that blade upwards pushes, and the effect of lifting of blade adds the circulation rate of mud, accelerates the formation of mud skin, reduces the generation of collapse hole phenomenon. This apparatus structure is simple, easy to operate, scarfing cinder efficiency high, the scarfing cinder degree of depth is deep, good in economic efficiency, and when extra-deep hole drilling bored concrete pile clear hole, effect is particularly evident.
The above is only the preferred embodiment of the present invention; it is not limited to the present invention; should be understood that; for those skilled in the art; under the premise without departing from the technology of the present invention principle; can also making some improvement and modification, these improve and modification also should be regarded as protection scope of the present invention.
