Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a construction method based on anti-floating prestressed anchor rods. Background Art

[0002] Anti-floating prestressed steel anchor rods are a type of structural component widely used in the anti-floating design of underground buildings. They are mainly designed by setting steel anchor rods under the structural base plate and applying prestress to achieve a balance between the structure's own weight and the buoyancy, thereby enhancing the building's anti-floating performance.

[0003] During transportation and storage, rebar anchor rods accumulate dust and rust. This rust can severely impact the bond between the rebar and the grouting material, reducing the overall anchoring quality. Existing rust removal methods often rely on manual labor, such as using wire brushes and electric grinding wheels to remove rust from each rod individually.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0033] like Figures 1-6 As shown, a construction method based on anti-floating prestressed anchor rods includes the following steps:

[0034] Step 1: Drill holes in the stratum where the anchor bolts are to be set, and use high-pressure water to clean out debris in the holes, such as mud and gravel, to ensure that the hole walls are clean and dry, improve the bonding strength between the hole walls and the subsequent grouting materials, reduce the adverse effects of the sediment at the bottom of the hole on the anchor bolt stress, and ensure the mechanical properties and durability of the anchoring system;

[0035] Step 2: Transport the anchor rods to the construction site. The construction site is equipped with dust-proof and moisture-proof mats. The anchor rods are placed on the dust-proof and moisture-proof mats. The thickness of the dust-proof and moisture-proof mats should be ≥ 0.5mm. Plastic sheets or moisture-proof felt can be used to prevent the anchor rod surface from absorbing dust again or getting rusted due to moisture.

[0036] Step 3: Use a rust removal device to remove rust from the anchor rod;

[0037] The rust removal device includes a cleaning device 1, which is provided with a processing chamber 2. The processing chamber 2 is connected to the outer wall of the cleaning device 1 through a rib inlet 3 and a rib outlet 4. The processing chamber 2 is provided with a liquid removal component, two liquid spraying components and three guide components. The two liquid spraying components are respectively provided with acid and alkali solution.

[0038] Step 4: Install the anchor rod into the hole and perform grouting operation.

[0039] According to an optional embodiment of the present invention, the guide assembly includes two transmission rollers 5 , and the transmission rollers 5 are rotatably connected to the inner wall of the processing chamber 2 .

[0040] According to an optional embodiment of the present invention, a motor 6 is fixedly connected to the inner wall of the processing chamber 2, and the output shaft of the motor 6 is fixedly connected to one of the transmission rollers 5.

[0041] According to an optional embodiment of the present invention, the outer wall of the driving roller 5 is covered with an anti-slip sleeve. Example

[0042] The anchor rod enters the processing chamber 2 from the rib inlet 3, and is guided between the two transmission rollers 5 of each guide assembly. Turning on motor 16 drives one of the transmission rollers 5 to rotate, thereby driving the anchor rod to move left. Pausing the operation of motor 16 can pause the anchor rod from moving left.

[0043] Use the right spray assembly to spray acid to remove rust from the anchor rod, move the anchor rod to the left, and use the left spray assembly to spray alkaline solution to neutralize the acid on the anchor rod. Use the liquid removal assembly to remove residual liquid from the surface of the anchor rod, and finally the anchor rod is separated from the cleaning device 1 from the reinforcement outlet 4.

[0044] In this embodiment, a guide component is provided so that the anchor rod can be stably guided between the two transmission rollers 5, and the transmission roller 5 is driven to rotate by the motor 16, thereby realizing stable and continuous movement of the anchor rod and improving the rust removal efficiency. The liquid outlet component 12 sprays acid and alkali respectively to achieve efficient automatic rust removal and neutralization treatment of the anchor rod, avoiding the problem of incomplete or omitted rust removal in manual operation. The liquid removal component can remove the residual liquid on the surface of the anchor rod to prevent the acid and alkali residues from corroding the anchor rod surface or affecting the adhesion of the subsequent epoxy coating. The overall structure is continuous and highly automated, which significantly improves the efficiency and construction quality of batch rust removal operations.

[0045] According to an optional embodiment of the present invention, the liquid removal component includes a support rod 15 and a transmission box 26 both fixed to the inner wall of the processing chamber 2, a transmission chamber 27 is provided on the transmission box 26, the inner wall of the transmission chamber 27 is connected to the outer wall of the transmission box 26 through a movable channel 28, a loading cylinder 29 and a cylinder 36 are fixed to the inner wall of the transmission chamber 27, a cylinder chamber 30 and a column channel 31 that are interconnected are provided on the loading cylinder 29, a transmission column 32 is slidably connected to the inner wall of the column channel 31, a threaded channel 33 is provided on the transmission column 32, and two or more cleaning components are placed in the cylinder chamber 30, and one cleaning component includes two cleaning cottons 2 4. A cotton hole 25 is provided on the cleaning cotton 24. A rack 23 is fixedly connected to the piston rod of the cylinder 36. A gear 38, a threaded rod 34 and a worm 35 are rotatably connected to the inner wall of the transmission chamber 27. The gear 38 is engaged with the rack 237. A worm wheel 39 engaged with the worm 35 is fixed to the gear 38. The worm 35 is fixed to the threaded rod 34. The threaded rod 34 is threadedly connected to the inner wall of the threaded channel 33. A movable cylinder 40 is slidably connected to the inner wall of the loading cylinder 29. The movable cylinder 40 is fixed to the rack 237. A cylinder channel 41 and a rib-threading channel 42 that are interconnected are provided on the movable cylinder 40. A cleaning component is placed on the inner wall of the cylinder channel 41.

[0046] According to an optional embodiment of the present invention, a waste liquid recovery component is provided on the inner wall of the processing chamber 2, and the waste liquid recovery component includes a receiving box 16 and a recovery box 22 fixed to the inner wall of the processing chamber 2. A receiving chamber 17 is provided on the receiving box 16, and the receiving chamber 17 is connected to the outer wall of the receiving box 16 through more than two liquid outlet holes 18. The inner wall of the receiving chamber 17 is slidably connected to a liquid squeezing plate 19, and a wedge-shaped piece 20 is fixed on the liquid squeezing plate 19. The liquid squeezing plate 19 is connected to the inner wall of the receiving chamber 17 through a spring 43. The inner wall of the transmission chamber 27 is slidably connected to a rack 23. The rack 123 and the rack 23 are respectively engaged with the gear 38, and the lower end of the rack 23 is fixed with a wedge-shaped piece 21.

[0047] According to an optional embodiment of the present invention, an inclined surface is provided on the inner wall of the cotton hole 25 . Example

[0048] The anchor rod passes through the reinforcement channel 42 and the cotton hole 25, and the inner wall of the cotton hole 25 abuts against the anchor rod, thereby clearing the liquid on the anchor rod, preventing the acid from corroding the anchor rod, and preventing the alkali solution and other substances from reacting to affect the adhesion performance of the epoxy coating and the anchoring performance of the anchor rod.

[0049] When the cleaning assembly in the barrel channel 41 needs to be replaced, the cylinder 36 controls the piston rod to shorten and drive the rack 37 to move upward, and the rack 37 drives the movable barrel 40 to move upward. When the movable barrel 40 moves above the cleaning assembly, the barrel channel 41 is separated from the support of the two cleaning cottons 24. The cleaning cottons 24 fall between the right wall of the receiving chamber 17 and the left wall of the squeezing plate 19 under the action of their own gravity.

[0050] The upward movement of rack 2 37 will drive gear 38, worm wheel 39, worm 35, and threaded rod 34 to rotate, and threaded rod 34 will drive transmission column 32 to move right, and transmission column 32 will move right to the right side of cylinder cavity 30. The cleaning component in cylinder cavity 30 will fall down to the height of a cleaning component after losing the support of transmission column 32, and the lowest cleaning component in cylinder cavity 30 will fall to contact with the bottom wall of transmission cavity 27, and gear 38 will drive rack 1 23 and wedge 2 21 to move downward, and wedge 2 21 will push wedge 1 20 to overcome the elastic force of spring 43 and move right, and liquid squeezing plate 19 will squeeze the cleaning cotton 24 in receiving cavity 17, so that the liquid in cleaning cotton 24 will be squeezed out through liquid outlet 18 and flow into recovery box 22 for waste liquid recycling, so that cylinder 36 will control piston The rod is extended to drive the rack 2 37 to move downward. When the movable cylinder 40 moves down to the point where the vertical distance between the bottom wall of the movable cylinder 40 and the top wall of the support rod 15 is less than the height of a cleaning component, the conveying column 32 moves left, pushing a cleaning component to move left and fall into the cylinder channel 41. The two cleaning cottons 24 are both against the support rod 15, and the inner wall of the cylinder channel 41 limits the two cleaning cottons 24 to prevent them from falling. The movable cylinder 40 continues to move downward until it is connected to the rib passage 42 and the two cotton holes 25 to facilitate subsequent anchor rod insertion. The wedge piece 21 moves up and disengages from the wedge piece 1 20. The squeezing plate 19 moves left and resets under the elastic force of the spring 43, so that the subsequent cleaning cotton 24 falls between the right wall of the receiving chamber 17 and the left wall of the squeezing plate 19, completing the replacement of the cleaning component.

[0051] This embodiment effectively removes residual liquid from the anchor rod surface by fitting the inner wall of the cotton hole 25 to the anchor rod, in conjunction with the cleaning cotton 24 in the barrel channel 41, thereby improving the cleanliness of the anchor rod surface. The movable barrel 40 is driven by the second rack 37 to move, enabling replacement of the cleaning component. The transmission column 32 and the threaded rod 34 cooperate to complete the transportation of the cleaning component. The rational structure facilitates replacement without manual intervention. The wedge 1 20 and the wedge 2 21 are linked to cooperate with the squeezing plate 19 to squeeze the waste liquid and flow it into the recovery box 22, achieving effective collection and utilization of the waste liquid, improving the automation level and environmental performance of the liquid removal process, and enhancing the overall consistency and stability of the anchor rod surface treatment.

[0052] According to an optional embodiment of the present invention, the liquid spraying assembly includes a liquid tank 7 and a motor 2 8 both fixedly connected to the inner wall of the processing chamber 2, a pump body 11 is fixedly connected to the inner wall of the box cavity on the liquid tank 7, a liquid outlet assembly 12 is fixedly connected to the liquid outlet on the pump body 11, the liquid outlet assembly 12 extends to the top of the liquid tank 7, the inner wall of the box cavity is inlaid with a copper plate 13, a disk body 9 is fixedly connected to the output shaft of the motor 2 8, two or more permanent magnets 14 are fixedly connected to the top wall of the disk body 9, a connecting rod 10 is also fixedly connected to the top wall of the disk body 9, and the connecting rod 10 is fixedly connected to the centrifugal impeller in the pump body 11.

[0053] According to an optional embodiment of the present invention, the liquid tank 7 is fixed to the inner wall of the processing chamber 2 through supporting legs, and the tray 9 is located below the copper plate 13. Example

[0054] Turn on motor 2 (8). The output shaft of motor 2 (8) drives the disk (9), permanent magnets (14), connecting rod (10), and centrifugal impeller (10) to rotate. All permanent magnets (14) continuously pass under copper plate (13), generating eddy currents inside copper plate (13) and generating heat. Copper plate (13) heats the liquid in the inner cavity of liquid tank (7), improving the rust removal and neutralization quality of the liquid when it contacts the anchor rod. The centrifugal impeller rotates, drawing the liquid from the inner cavity of liquid tank (7) to the liquid outlet assembly (12) for spraying onto the surface of the anchor rod, thereby removing rust and neutralizing the liquid. After contacting the anchor rod, the liquid falls back into liquid tank (7) for reuse, preventing waste. The liquid sprayed from the right liquid outlet assembly (12) is acidic, while the liquid sprayed from the left liquid outlet assembly (12) is alkaline.

[0055] In this embodiment, the motor 2 8 drives the disk 9 to rotate, and the permanent magnet 14 is used to rotate at high speed under the copper plate 13 to generate eddy heat, so that the liquid in the liquid tank 7 is heated, and the reaction rate of the acid and alkali solution and the rust removal and neutralization effects are improved. It is especially suitable for low temperature or high rust removal requirements. The connecting rod 10 drives the centrifugal impeller in the pump body 11 to spray the heated liquid onto the surface of the anchor rod through the liquid outlet component 12, realizing the integration of rust removal and neutralization treatment, and the liquid is reused through natural reflux, reducing material waste, complying with the concept of green construction, integrating heating, pumping, and spraying, and improving the efficiency and effect of anchor rod rust removal and cleaning treatment.

[0056] According to an optional embodiment of the present invention, after the anchor rod is derusted, an epoxy coating is applied to the anchor rod. The epoxy coating has excellent anti-corrosion properties and can effectively isolate air and moisture, preventing the anchor rod from rusting in a humid or corrosive environment underground, thereby extending the service life of the anchor rod.

[0057] The components, modules, mechanisms and devices not described in detail in the present invention are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
