Description
Technical Field
The invention relates to a hole expanding device, in particular to an anchoring hole bottom hole expanding device, and belongs to the technical field of anchoring.
Background
The earth anchor rod is made up by drilling hole in the earth layer of deep foundation wall, after reaching a certain depth, placing the materials of reinforcing bar, steel pipe, steel wire bundle and steel strand into the hole, and pouring slurry or chemical grout to make it combine with earth layer to form the anchor rod with strong tensile (pulling) resistance.
At present, no soil anchor rod for resisting floating exists, and the traditional engineering adopts an anti-floating pile to realize the function. However, compared with the hole drilled by the soil anchor rod, the anti-floating pile has larger aperture and no hole expansion at the bottom, and the ultimate uplift force of a single anti-floating pile is smaller than that of the soil anchor rod; meanwhile, the cost is higher than that of a soil anchor rod, and the use requirement is difficult to meet.
Disclosure of Invention
The invention aims to provide a hole bottom reaming device for an anchoring hole, aiming at the problems that the hole diameter of the existing anti-floating pile is larger than that of a soil anchor rod, the bottom of the existing anti-floating pile is not reamed and the like.
In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides an anchor hole bottom reaming device, includes rotatory sleeve, rotatory sleeve sets up in the anchor hole, rotatory sleeve in be provided with water injection pipe and the pipe of drawing water, be provided with the rubber buffer between rotatory sleeve lower part outer wall and the anchor pore wall, water injection pipe bottom be connected with the spray pipe, the spray pipe export be the water jet, the spray pipe is fixed on rotatory sleeve through rotatable support, the spray pipe can rotate around the water injection pipe.
The rotatable angle of the water spray pipe is 15-45 degrees, the angle is an included angle between the water spray pipe and a vertical line of a ground plane when the water spray pipe rotates, the rotatable bracket is provided with four rotation gears, and the four rotation gears respectively correspond to the rotatable angles of the water spray pipe, namely 15 degrees, 25 degrees, 35 degrees and 45 degrees.
The water injection conduit and the water pumping conduit are fixed in the rotary sleeve through the fixed support.
Compared with the prior art, the invention has the beneficial effects that:
the hole bottom reaming device for the anchoring hole has small hole diameter of drilling, is convenient to construct and is relatively economical.
Drawings
FIG. 1 is a schematic view of the present invention.
FIG. 2 is a view showing the first water spraying pipe rotating in the present invention.
FIG. 3 is a view showing the rotation of the water jet pipe according to the present invention.
In the figure, a rotating sleeve 1, a water injection conduit 2, a water pumping conduit 3, a rubber plug 4, a water spraying pipe 5, a rotatable bracket 6 and a fixed bracket 7.
Detailed Description
The invention is described in further detail below with reference to the following description of the drawings and the detailed description.
Referring to fig. 1 to 3, an anchoring hole bottom reaming device comprises a rotating sleeve 1, wherein the rotating sleeve 1 is arranged in an anchoring hole, and the rotating sleeve 1 can rotate in the anchoring hole for 360 degrees; the rotary sleeve 1 is provided with a water injection conduit 2 and a water pumping conduit 3, a rubber plug 4 is arranged between the outer wall of the lower part 1 of the rotary sleeve and the anchoring hole wall, and the rubber plug 4 plays a role in sealing. The bottom of the water injection conduit 2 is connected with a rotatable water spray pipe 5, the outlet of the water spray pipe 5 is a water spray opening, the water spray pipe 5 is fixed on the rotary sleeve 1 through a rotatable support 6, and the water spray pipe 5 can rotate around the water injection conduit 2.
Referring to fig. 1 to 3, further, the rotation angle of the spray pipe 5 is 15 to 45 °, which is the angle between the rotation of the spray pipe 5 and the vertical line of the ground plane; the rotatable bracket 6 is provided with four rotation gears which respectively correspond to the rotation angles of 15 degrees, 25 degrees, 35 degrees and 45 degrees of the water spray pipe 5.
Referring to fig. 1 to 3, in particular, the water injection conduit 2 and the water suction conduit 3 are fixed in the rotating sleeve 1 by a fixing bracket 7.
Referring to fig. 1 to 3, when the hole expanding device is used for forming a hole, firstly, a geological drill or a down-the-hole drill is used for drilling an anchoring hole straight hole, and then a water injection conduit 2 and a water pumping conduit 3 are fixed in a rotary sleeve 1 through a fixed support 7, so that the bottoms of the water injection conduit 2 and the water pumping conduit 3 extend out of the rotary sleeve 1; and then the rotating sleeve 1 is placed in the straight hole of the anchoring hole. And then the water injection conduit 2 is communicated with an external high-pressure water pipe, the water pumping conduit 3 is communicated with an external high-pressure water pump, the inner wall of the bottom of the anchoring hole is cut by jet flow through the water injection conduit 2, and simultaneously slurry at the bottom of the hole is pumped by adopting the high-pressure water pump through the water pumping conduit 3. The rubber plug 4 between the outer wall of the lower part 1 of the rotary sleeve and the anchoring hole wall can prevent water from flowing out from the rotary sleeve and the hole wall when the water injection conduit 2 performs jet cutting on the inner wall of the bottom of the anchoring hole, so that the hole wall above the rubber plug 4 is damaged by scouring, and hole collapse is caused. And then after the high-pressure jet flow pin hole is finished, keeping the high-pressure water pump to continuously pump the hole bottom slurry through the water pumping guide pipe 3 until the cement slurry pumped out by the high-pressure water pump is reduced, and stopping pumping. Finally, the height of the water injection conduit 2 is adjusted so as to adjust the angle of the rotatable bracket 6, and the method is convenient for pulling out the rotary sleeve 1; and then taking out the whole rotating sleeve 1 to complete the hole bottom reaming process of the anchoring hole of the soil anchor rod, and performing the subsequent soil anchor rod implantation process. When the water injection conduit 2 cuts the inner wall of the bottom of the anchoring hole by jet flow, the rotatable bracket 6 can be adjusted to a position corresponding to the rotatable angles of 15 degrees, 25 degrees, 35 degrees and 45 degrees of the water spray pipe 5, and the rotating sleeve 1 is slowly rotated to rotate for 1-2 weeks and is pumped by a high-pressure water pump to extract slurry in the bottom hole; and finishing the high-pressure jet pin hole until the inner wall of the bottom of the anchoring hole is formed.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention relates, several simple deductions or substitutions may be made without departing from the spirit of the invention, and the above-mentioned structures should be considered as belonging to the protection scope of the invention.
