Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating the utility model, but are not limited to scope of the present utility model.
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 paddle 2, described paddle is made up of blade 3 and propeller hub 4, described propeller hub encloses and binds round on described drilling rod, and described blade at least two panels and blade face are 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 is less than 180 degree.
Paddle is fixed on drilling rod by the hoop effect of enclosing of two panels propeller hub.After stacks, paddle being inserted in drilling rod, paddle can be multiple, needs to be arranged on drilling rod with a determining deviation according to construction, then is fastened by 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.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.
Primary structure of the present utility model is paddle, and paddle is made up of blade, two lobe propeller hubs, fastening bolt, pin.Blade and propeller hub are made 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 paddle under send during be damaged or stake inwall 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 make of 0.3mm steel plate, propeller hub can make of 0.5mm steel plate, 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, paddle being inserted in a certain position of drilling rod, blade blade face is upwards and neighbouring paddle horizontal direction is vertical, and paddle is together transferred with drilling rod after being fastened by two pieces of bolts, operates according to this and installs paddle with a determining deviation.When boring is to when specifying absolute altitude, stops 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 paddle, accelerate the more mud of suspension boring mud in hole and swap out speed.
This cast-in-situ bored pile hole cleaning device, including drilling rod and paddle.During direct circulation revolution once clear hole, drilling rod drives the paddle being fixed thereon to rotate, and coordinates the idle running of drill bit, effectively the sediment risen at the bottom of stake is the most upwards pushed, 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 the mud that blade upwards pushes has rendering effect to hole wall, 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 and convenient 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 preferred embodiment of the present utility model; it is not limited to the utility model; should be understood that; for those skilled in the art; on the premise of without departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
