Description

Technical Field

[0001] The invention relates to the field of anchor rod grouting devices, in particular to an environmentally friendly gravel slope anchor rod grouting device capable of reducing grouting. Background Art

[0002] Gravel slopes are usually loose in structure and have poor stability. Anchor rods can penetrate deep into the slope, connect loose gravel particles together to form a whole, and enhance the anti-slip ability and stability of the slope. Anchor rods are rods that penetrate deep into the ground or rock, usually made of steel bars or steel strands. Anchor rods can continue to play a role for a long time, providing a guarantee for the long-term stability of the slope. Anchor grouting is to inject cement slurry or other suitable slurry into the gaps and rock and soil around the anchor rods through certain equipment and methods after the anchor rods are placed in the predetermined position. Anchor grouting enhances the bonding force between the anchor rods and the surrounding rock and soil, so that the anchor rods can better play the anchoring role and improve the stability of the slope.

[0003] Grouting is a key process in the anchor construction of gravel slopes. However, the traditional grouting device often has grouting phenomenon during construction, which not only causes material waste, but also pollutes the construction environment. In addition, grouting may also lead to poor anchoring effect of the anchor and affect the stability of the slope. Therefore, we propose an environmentally friendly gravel slope anchor grouting device that reduces grouting in order to solve the above problems. Summary of the invention

[0028] Example

[0029] Please refer to Figure 1-6As shown, the present invention provides an environmentally friendly gravel slope anchor grouting device that reduces grouting.

[0030] A hollow connecting tube 2 is fixedly installed on the outer end of the self-advancing anchor rod 1, and an elastic seal 3 is slidably installed on the outer end of the hollow connecting tube 2. A limit plate 4 is fitted on the outer wall of the elastic seal 3, and an adjusting member 5 is integrally installed on the outer end of the limit plate 4. The adjusting member 5 is threadedly connected to the outer wall of the hollow connecting tube 2, and a micro bolt 6 is threadedly connected to the inner end of the adjusting member 5. A drill bit 20 is fixedly installed on the other end of the self-advancing anchor rod 1 away from the hollow connecting tube 2, and the self-advancing anchor rod 1 is connected to the pressure detector 13 through the hollow connecting tube 2. The position of the elastic seal 3 is adjusted by rotating the adjusting member 5, and the adjusting member 5 is provided in two groups in a semicircular structure. The elastic seal 3 is fitted on the orifice of the drill hole to prevent the slurry from overflowing when it does not reach the predetermined position, thereby effectively preventing the slurry from returning from the gap between the self-advancing anchor rod 1 and the hole wall;

[0031] The mounting ring 7 is fixedly mounted on the outer end of the hollow connecting pipe 2, and a card slot 8 is provided at the inner end of the mounting ring 7, and a card member 9 is mounted on the inner end of the card slot 8, and a straight plate frame 10 is integrally mounted on the lower end of the card member 9, and a wire 11 is fixedly mounted on the inner end of the straight plate frame 10, and a waterproof net bag 12 is fixedly mounted on the outer end of the wire 11, and the shape of the waterproof net bag 12 is adjusted by bending the wire 11, and the waterproof net bag 12 is arranged on the lower side of the elastic sealing member 3, so as to facilitate the collection of the outflowing slurry, avoid waste of materials, and will not cause pollution to the construction environment, and facilitate subsequent cleaning;

[0032] The pressure detector 13 is fixedly mounted on the outer end of the hollow connecting pipe 2, and a pressure gauge 14 is fixedly mounted on the inner end of the pressure detector 13. A regulating valve 15 is threadedly connected to the inner end of the pressure detector 13. A slurry inlet 16 is fixedly mounted on the outer end of the regulating valve 15, and a slurry delivery pipe 17 is fixedly mounted on the outer end of the slurry inlet 16. A grouting machine 18 is connected to the lower end of the slurry delivery pipe 17, and a roller 19 is fixedly mounted on the lower end of the grouting machine 18. The grouting machine 18 transports slurry to the inside of the self-propelled anchor 1 through the slurry delivery pipe 17 for grouting. After the grouting is completed, the self-propelled anchor 1 is separated from the hollow connecting pipe 2. The grouting pressure can be reasonably adjusted through the regulating valve 15 to avoid excessive penetration and return of slurry caused by excessive pressure.

[0033] Specific working principle:

[0034] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, when the environmentally friendly gravel slope anchor grouting device for reducing grouting is used, the self-propelled anchor 1 is drilled into the gravel slope through the drilling device, and then the drilling device is detached from the self-propelled anchor 1, the hollow connecting pipe 2 is connected to the self-propelled anchor 1, and then the grouting device inside the grouting machine 18 transports the slurry to the inside of the pressure detector 13 through the grouting pipe 17, and then flows into the inside of the hollow connecting pipe 2, and enters the inside of the self-propelled anchor 1 for grouting. During the grouting process, the pressure of the slurry is displayed on the pressure gauge 14. If the pressure inside the borehole is too high, the risk of grouting increases. When the pressure is too high, the regulating valve 15 is turned downward, and the regulating valve 15 intercepts the slurry flowing inside the pressure detector 13, slows down the grouting rate, and adjusts the grouting pressure to avoid excessive penetration and grouting of the slurry caused by excessive pressure;

[0035] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in order to prevent the slurry from flowing out, the adjusting member 5 can be rotated in the direction of the self-advancing anchor rod 1, and the adjusting member 5 moves in the direction of the self-advancing anchor rod 1 at the outer end of the hollow connecting tube 2, so that the adjusting member 5 drives the limiting plate 4 to move in the direction of the elastic sealing member 3, so that the elastic sealing member 3 and the hole opening fit more closely. Due to the sealing effect, the slurry can only flow along the preset path, which greatly reduces the occurrence of the slurry return phenomenon. When it is necessary to remove the adjusting member 5, the micro bolt 6 threadedly connected to the inner end of the adjusting member 5 is removed. After the micro bolts 6 on the upper and lower sides are removed, the two groups of adjusting members 5 can be separated, and the adjusting member 5 is taken down from the hollow connecting tube 2, and the limiting plate 4 is removed together with the adjusting member 5;

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the iron wire 11 can be bent into a certain shape. During grouting, the iron wire 11 is turned to make the edge of the waterproof net bag 12 fit with the gravel slope, so that the cement slurry that inevitably flows out flows into the waterproof net bag 12 for collection. After use, the straight frame 10 is pushed, and the straight frame 10 drives the clamping member 9 to slide on the inner side of the clamping slot 8. When the clamping member 9 is separated from the clamping slot 8, the waterproof net bag 12 can be removed for recycling or disposal. The above completes a series of operations of the environmentally friendly gravel slope anchor grouting device for reducing grouting. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
