Drawings
Fig. 1 is a schematic structural diagram of a cross jet flow mixing and spraying pile construction device according to an embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The following describes the implementation of the present invention in detail with reference to specific embodiments.
As shown in fig. 1, the embodiment of the present invention provides a cross jet flow mixing-grouting pile construction equipment, which comprises a drill rod 1, a mixing blade 2 disposed on the drill rod 1, a first guniting blade 3 disposed on the drill rod 1, a second guniting blade 4 disposed below the first guniting blade 3, and a drill bit 5 disposed at the bottom end of the drill rod 1. Stirring vane 2 first guniting blade 3 the stake diameter that second guniting blade 4 rotatory a week becomes is the same, and concrete size sets up the blade size according to the demand. The drill 5 is a spiral drill.
The end of the first guniting blade 3 and the end of the second guniting blade 4 are respectively provided with a first guniting nozzle 31 and a second guniting nozzle 41 for spraying grout. The first slurry spraying nozzle 31 and the second slurry spraying nozzle 41 are respectively used for spraying high-pressure slurry to cut soil. The first guniting nozzle 31 and the second guniting nozzle 41 form a set angle, so that ejected grout is converged in a soil body, and the distance between a convergence point 7 and the central line of the drill rod is greater than the radius of the stirring blade 2, so that the diameter of a pile foundation is increased through a jet flow on the basis of mechanical pile forming of the stirring blade 2. It should be noted that the angles of the first guniting nozzle 31 and the second guniting nozzle 41 are adjustable, so that an operator can preset the angles of the first guniting nozzle 31 and the second guniting nozzle 41 as required before piling, so as to adjust the intersection point of the grout sprayed from the two guniting nozzles, and further control the diameter of the pile. The high pressure slurry may be a curing agent slurry, so that the soil body can be cured after being cut.
In the embodiment of the utility model provides an in, stirring vane 2 set up in first spouting blade 3 with 4 tops of second spouting blade. The number of the first guniting blades is two, and the first guniting blades are symmetrically arranged on the drill rod. The two second guniting blades are symmetrically arranged on the drill rod.
Further, in the embodiment of the present invention, the cross jet flow mixing pile construction equipment further includes a power device for driving the drill rod, the mixing blade, the first guniting blade and the second guniting blade, and a high-pressure slurry pump for providing slurry for the first guniting nozzle 31 and the second guniting nozzle 41. It should be noted that a slurry passage (not shown) communicating with the first slurry nozzle 31 and the second slurry nozzle 41 is provided inside the drill rod, so that the high-pressure slurry pump can supply slurry to the first slurry nozzle 31 and the second slurry nozzle 41 through the slurry passage.
The construction process of the cross jet flow mixing and spraying pile construction equipment comprises the following steps:
firstly, before a drill rod 1 is sunk and drilled, setting the injection angles of a first guniting blade 3 and a second guniting blade 4 according to design requirements so as to control the diameter of a pile;
in the sinking process of the drill rod 1, starting a high-pressure slurry pump corresponding to the first slurry spraying nozzle 31 and the second slurry spraying nozzle 41, so that the jet flows formed by the first slurry spraying nozzle 31 and the second slurry spraying nozzle 41 form an intersection angle and are converged at one point;
the triangular jet area 7 formed by the jet flows cuts soil along with the rotation of the drill rod, the soil outside the intersection point 6 is only slightly disturbed due to the energy loss of the jet flows, and therefore the effective diameter of the formed mixing pile 8 is the diameter of a circle formed by one rotation of the intersection point 6.
When the jet flow expanding diameter is not needed, the guniting pressure can be reduced, so that the first guniting blade and the second guniting blade only carry out mechanical stirring and do not carry out the work of cutting soil bodies by the jet flow.
In conclusion, the cross jet flow mixing and spraying pile construction equipment integrates the advantages of two pile forming processes of mixing and rotary spraying, and the jet flow increases the diameter of the pile foundation on the basis of mechanical pile forming of the mixing blades; meanwhile, the jet flow is ejected from the ends of two blades which are adjacent up and down, the opposite jet is formed according to the oblique angle, and the energy of the high-pressure jet flow is dissipated at the intersection, so that the diameter of the pile is determined at the intersection. The pile body formed by the method can be close to the underground structure for construction, and has the advantages of large pile forming diameter, high work efficiency and definite pile forming diameter.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
