Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Embodiment
The embodiment of the present invention provides a kind of square cement agitation pile rig, referring to Fig. 1, described square cement agitation pile rig comprises frame 1, be arranged on pylon bracket 2 in frame 1, be arranged on drive unit 3, the pylon 4 being connected with pylon bracket 2 on pylon bracket 2, be arranged on drilling rod 5 on pylon 4, be arranged on the unit head 6 of drilling rod 5 one end, cement paste grouting device 7, the drill bit 8 that is arranged on drilling rod 5 other ends being connected with drilling rod 6, the casing 9 that is arranged on drilling rod 5 outsides.
Particularly, frame 1 comprises the frame crawler belt 11 that is arranged on frame 1 end.
Particularly, drive unit 3 comprise be arranged on pylon bracket 2 one sides rig driver's cabin 31, be arranged on the motor 32 of pylon bracket 2 opposite sides.
Particularly, pylon 4 comprises the steel wire rope of windlass 41 being arranged on pylon 4, the pylon oil cylinder 42 that connects pylon 4 and pylon bracket 2.
Particularly, referring to Fig. 2, drilling rod 5 is arranged on pylon 4 one sides, and drilling rod 5 comprises drilling rod core pipe 51, is arranged on the tool joint 52 of drilling rod core pipe 51 one end.
Particularly, cement paste grouting device 7 comprises the cement paste Grouting Pipe 71 being connected with unit head 6, the cement paste grouting pump 72 being connected with cement paste Grouting Pipe 71.
Particularly, referring to Fig. 3, drill bit 8 is arranged on drilling rod core pipe 51, and drill bit 8 comprises and is arranged on cutting native cutter head 81, be arranged on and cut cutting native blade 82, be arranged on the native edge of a knife 83 of cutting of cutting on native blade 82 on native cutter head 81 on drilling rod core pipe 51.Drill bit 8 cross sectional shapes are for strangling Lip river triangle.
Particularly, casing 9 cross sectional shapes are for strangling Lip river triangle.Strangling Lip river triangle feature is: taking the each summit of equilateral triangle as the center of circle, taking the length of side as radius, at one section of arc of another two summit intercropping, the curved line trangle that three sections of arcs surround is strangled Lip river triangle (reuleaux triangle) exactly.Strangling Lip river triangle the same with circle is typical curve of constant breadth.The concept of curve of constant breadth: the curve with (similar circle) fixed width is called curve of constant breadth.Fixed width, understanding is geometrically: a circle is placed in the middle of two parallel lines, makes it tangent with these two parallel lines.Can accomplish: no matter how this circle moves, it or in these two parallel lines, and tangent with these two parallel lines all the time.Because strangle the leg-of-mutton fixed width in Lip river, so drop it off in a foursquare hole, it can " be blocked " can not translation, can freely rotate again.Certainly fenestra has such character, but circle and square border only have 4 point of contacts, and it is very large to strangle the point of contact scope of Lip river triangle on square, according to calculating, the scope length that Shang Le Lip river, square border triangle can switch to is mutually the √ 3-1 ≈ 73.2% of the length of side, can get out approximate foursquare fillet square so strangle Lip river triangle drill bit.
Wherein, the high 25m ~ 35m of frame, stride or crawler-type traveling, use motor or Diesel Driven hydraulic oil pump; Rig driver's cabin is at the front left side of frame, intellectualized operation; When rig transhipment, boring tower is flat to crouch in frame, and when pore-forming, boring tower is holded up by hydraulic jack, flexible hydraulic jack capable of regulating boring tower verticality; Unit head is connected by slideway with boring tower, and main winch pulls unit head to prolong boring tower and moves up and down.
The beneficial effect that the technical scheme that the embodiment of the present invention provides is brought is:
Equipment operating step is few, easily grasps, and has all advantages of conventional cement mixing pile, and pile cross sectional shape is square, in pore forming process, uninterruptedly creeps into, and hole wall is complete; Can work continuously, production efficiency is high, not limited by site condition; Can quadrate stake, reduce a stake sectional dimension, improve bearing capacity of single pile and reduce pile spacing.
For building, bridge, road, municipal ground process a kind of new pile-forming drilling machine of cement mixing pile driving construction, this rig pile cross sectional shape is square, improve bearing capacity of single pile with respect to circular agitation pile, reduce the spacing of stake, reduced the cost of building, bridge, road, municipal Foundation Design.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
