Description

A kind of super three axle cement mixing pile equipment
Technical field
The present invention relates to a kind of Construction of Civil Engineering equipment, particularly the super three axle cement mixing pile equipment of one.
Background technology
SMW engineering method is also known as Rigid cable method, namely in cement earth pile, inserting H profile steel etc., (most is H profile steel, also have and insert Larsen formula steel sheet pile, steel pipe etc.), bearing load is combined with antiseepage dash, makes it to become the enclosure wall of the supporting and protection structure simultaneously with stressed and impervious two kinds of functions.SMW engineering method has made the outstanding contribution of 20 years nearly in the application of China's building field.Commonplace in the application of the coastal soft clay area such as China Shanghai, Jiangsu, Zhejiang, Tianjin at present, and be progressively generalized to the areas such as Fujian, Anhui, Hubei.Mainly for solving, dual spindle soil-cement agitation pile adjacent studs overlap joint is incomplete, one-tenth pile verticality is comparatively difficult to ensure the problems such as card for triaxial cement mixing pile equipment.
Chinese patent CN101864765B discloses a kind of SMW construction based on two-way stirring and tri-axial stirring equipment, comprises chassis, frame, power box, three drilling rods; Erecting is on chassis, and power box is connected in the upper end of three drilling rods, drives three drilling rods respectively; Each drilling rod bottom is provided with drill bit; The axle center of three drilling rods is located along the same line, and the stirring drilling rod of dual-side axle is two-way stirring drilling rod, and the stirring drilling rod of jackshaft is unidirectional stirring drilling rod, and jackshaft is provided with air pipe; The stirring drilling rod of described dual-side axle comprises inside and outside drilling rod, and inside and outside drilling rod at least arranges two groups of stirring vanes respectively, and stirring vane axially sets gradually along drilling rod; The rotation direction of inside and outside drilling rod is contrary.Adopt this equipment to be suitable for the soil layers such as cohesive soil, silt, sand, gravel soil and Saturated loess soil, but when running into the soil layer having cobble or circle gravel, pile difficulty, cement mixing method is just not suitable for using at this type of soil layer.
Summary of the invention
The technical problem that will solve of the present invention is to provide a kind of super three axle cement mixing pile equipment, is adapted at the soil layer construction such as cobble or circle gravel, guarantees the pile quality in cobble or gravel layer, ensure the safety of deep pit construction.
In order to solve the problems of the technologies described above, the invention provides a kind of super three axle cement mixing pile equipment, comprising chassis, frame, power set and three drilling rods, frame is arranged on chassis, and power set are arranged on the top of three drilling rods, drive three drilling rods respectively, three drilling rods are connected to three drill bits, it is characterized in that, three described drilling rods are axially parallel, each drilling rod is provided with bearing support, and three bearing support centers are in a plane.
Further, described the right and left drilling rod is provided with at least one pair of blade, described blade is positioned at the top of bearing support.
Further, described blade is blade type.
Further, drilling rod casing is provided with below described bearing support.
Further, described drill bit is provided with three bit drills teeth, described bit drills tooth is rectangular pyramid, and wherein the bit drills denticle on both sides amasss and is greater than middle bit drills tooth.
Further, it is characterized in that, described the length of the bit is 0.8m.
The technique effect adopting equipment of the present invention to produce is:
1, the present invention can be used for cobble or the gravel layer construction of diameter 2 ~ 200mm, and pile-forming effect is good, and stagnant water effect is desirable, and power set strengthen and add stepless shift function simultaneously, and pile-forming speed is fast, and the duration shortens nearly half.
2, by improving the blade shape of drilling rod, spirally change blade type into by traditional, increase the space between blade, blade type blade also can stir the cobble in stratum fully simultaneously, thus ensure that the pile quality of cement mixing pile.
3, to wear and tear in boulder bed too large situation for drilling rod, a drilling rod casing is welded in lower support frame, decrease the wearing and tearing of cobble to drilling rod and the replacement frequency of drilling rod, this casing also can be removed and be attached to cement paste on drilling rod and drill bit and cohesive soil, decrease the workload of artificial removal, improve efficiency of construction.
4, for the situation of bit wear, improve the form of bit drills tooth, shorten the length of the bit, while being convenient for changing, decrease the wearing and tearing of drill bit.
Accompanying drawing explanation
Fig. 1 is the structural representation of present device;
Fig. 2 is the structural representation of blade of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
As shown in Figure 1, the present invention includes and comprise chassis, frame, power set and three drilling rods 4, frame is arranged on chassis, power set are arranged on the top of three drilling rods, drive three drilling rods respectively, three drilling rods are connected to three drill bits, 5, three drilling rods and are parallel to each other, each drilling rod is provided with bearing support 2, three bearing support centers are in same plane.The below of bearing support is provided with bearing support casing 3, decreases the wearing and tearing of cobble to drilling rod and the replacement frequency of drilling rod, also greatly can remove and be attached to cement paste on drilling rod and drill bit and cohesive soil.
As shown in Figure 2, the right and left drilling rod is provided with at least one pair of blade 1, blade is positioned at the top of bearing support 2, and blade is blade type.By improving the blade shape of drilling rod, spirally change blade type into by traditional, increase the space between blade, blade type blade also can stir the cobble in stratum fully simultaneously, thus ensure that the pile quality of cement mixing pile.
For the situation of bit wear, improve the form of bit drills tooth 6, drill bit shortens simultaneously, shortens to 0.8m, decrease the wearing and tearing of drill bit while being convenient for changing by traditional 1.3m is long.Bit drills tooth is rectangular pyramid, wherein the bit drills denticle on both sides amasss and is greater than middle bit drills tooth, brill tooth and cobble contact area have diminished, bore gap between tooth simultaneously and become large, cobble can not be stuck on drill bit, may be used for cobble or the gravel layer construction of diameter 2 ~ 200mm, pile-forming effect is good, and stagnant water effect is desirable.
