Description

Technical Field

[0001] The invention relates to the technical field of anti-floating anchors, and more particularly to an anti-floating anchor for long-distance pipelines and a construction method thereof. Background Art

[0002] Long-distance pipelines are buried underground. Due to the high groundwater level, the pipeline sections will be lifted and suspended, which may cause pipeline rupture. To deal with this phenomenon, anti-floating anchor devices are installed at both ends of the pipeline to solve the problem of pipeline sections being lifted and suspended due to the influence of water level.

[0003] And according to the size specifications of the pipeline diameter, if the pipeline diameter is too large, it is necessary to install a large diameter anti-floating anchor, otherwise it is necessary to install a small diameter anti-floating anchor. However, the current anti-floating anchor cannot change with the size of the pipeline diameter, so it is necessary to carry an anti-floating anchor that adapts to the pipeline diameter according to the diameter of the installed pipeline, which makes the entire construction process complicated. At the same time, if the calculation is wrong, the carried anti-floating anchor will not meet the anti-floating standard of the pipeline, and then it is necessary to re-select an anti-floating anchor that is suitable for the pipeline, which may cause the overall project to be delayed.

[0013] Preferably, a construction method for long-distance pipeline anti-floating anchor comprises the following steps:

[0014] S1. First, plan the anchor hole points on both sides of the pipeline, and then use a drilling machine to drill holes of the size that meet the diameter of the straightened pipeline according to the diameter of the pipeline, and then clean the holes. At this time, insert the anti-floating anchor rod into the anchor hole, and then penetrate the guide rods set on both sides of the output end of the driving motor through the holes set on the outer surface of the first sliding component, and penetrate the holes set on the outer surface of the second sliding component, and then connect the output end of the driving motor with the bidirectional threaded rod through a spiral, and then start the driving motor to drive the bidirectional threaded rod to rotate. At this time, the guide rod plays a guiding role, allowing the first sliding component and the second sliding component to move along the guide rod to the middle part of the bidirectional threaded rod;

[0015] S2, when the first sliding assembly and the second sliding assembly move toward the middle of the bidirectional threaded rod, they drive one end of the first expansion block and the second expansion block to move toward the middle, so that the connection between the first expansion block and the second expansion block expands in a direction away from the bidirectional threaded rod, and then drives the arc-shaped expansion plate to expand in a direction away from the bidirectional threaded rod until the arc-shaped expansion plate contacts the edge of the hole;

[0016] S3, and when the bidirectional threaded rod rotates, it will drive the rotation of the cylindrical connecting block, thereby driving the rotation of the connecting rod, and then driving the circular connecting block to rotate, and the rotation of the circular connecting block will drive the conical barrel to rotate, thereby driving the second circular connecting block to rotate, and then driving the threaded rod to rotate, and the rotation of the threaded rod will drive the circular sliding block to move downward along the threaded rod, thereby driving the rectangular sliding block to move downward along the rectangular slide groove, and then driving the fixed rod to expand to the surroundings until one end of the fixed rod fits in the surrounding soil, when the fixed rod fits in the soil, the second anchor rod placement block set in the inner cavity of the circular connecting block corresponds to the first anchor rod placement block, and then the drive motor is removed;

[0017] S4. When the driving motor is removed, the lower end of the connecting mechanism is connected to the bidirectional threaded rod through a spiral, and then the steel bar is inserted into the middle hole of the first anchor rod placement block, and then inserted from the first anchor rod placement block into the middle hole of the second anchor rod placement block to form an anchor rod. Then a grouting machine is used to inject grout from the inner cavity of the connecting mechanism, and the slurry will flow to the inner cavity of the conical barrel through the hollow structure of the bidirectional threaded rod, and the slurry in the inner cavity of the conical barrel will flow to the borehole through the slurry outlet hole until the borehole is filled with slurry. Two hours after the cement slurry is filled, a secondary high-pressure grouting operation is performed using a grouting machine, and the above grouting operation is repeated. After the grouting is completed, wait for the cement slurry to solidify completely, and then the two ends of the straightening belt are sleeved in the circular grooves in the connecting mechanism to fix and straighten the pipeline, and end all operations.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] (1) In the present invention, the bidirectional threaded rod is driven to rotate by starting the driving motor, and the rotation of the bidirectional threaded rod drives one end of the first expansion block and the second expansion block to move toward the middle, so that the connection between the first expansion block and the second expansion block expands to the surroundings, and then drives the arc-shaped expansion plate to expand to four directions until the arc-shaped expansion plate contacts the edge of the hole. In this way, the diameter of the anti-floating anchor can be adjusted according to the diameter of the drilled hole, which can achieve a convenient effect and does not require deliberately selecting anti-floating anchors of different diameters. At the same time, it can effectively improve the construction efficiency and allow the pipeline to quickly enter the working state, thereby reducing the loss caused during the construction process.

[0020] (2) In the present invention, the rotation of the bidirectional threaded rod drives the rotation of the cylindrical connecting block, thereby driving the threaded rod to rotate. As the threaded rod rotates, the circular sliding block is driven to move downward along the threaded rod, thereby driving the rectangular sliding block to move downward along the rectangular slide groove, and then driving the fixed rod to expand in all directions until one end of the fixed rod fits into the surrounding soil. This can fix the anti-floating anchor, thereby preventing the anti-floating anchor from being affected by the groundwater level, thereby increasing the anti-floating effect on the pipeline and increasing the service life of the anti-floating anchor.

[0021] (3) In the present invention, the tensioning belt can be replaced by spirally connecting the lower end of the connecting mechanism to the bidirectional threaded rod. If the tensioning belt is corroded by rainwater and microorganisms for a long time, the anti-floating fixing effect of the tensioning belt is weakened. At this time, it is only necessary to remove the connecting mechanism and replace it with a new one. This increases the service life of the anti-floating anchor and also facilitates maintenance operations on the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] A construction method for long-distance pipeline anti-floating anchor includes the following steps:

[0043] S1. First, plan the anchor hole points on both sides of the pipeline, and then use a drilling machine to drill holes of the size that meet the diameter of the straightened pipeline according to the diameter of the pipeline, and then clean the drilled holes. At this time, insert the anti-floating anchor rod into the anchor hole, and then connect the driving motor with the bidirectional threaded rod 3 through a screw, and then start the driving motor to drive the bidirectional threaded rod 3 to rotate, and the rotation of the bidirectional threaded rod 3 will drive the first sliding component 4 and the second sliding component 6 to move to the middle part of the bidirectional threaded rod 3;

[0044] S2, when the first sliding assembly 4 and the second sliding assembly 6 move toward the middle of the bidirectional threaded rod 3, they will drive one end of the first expansion block 503 and the second expansion block 505 to move toward the middle, so that the connection between the first expansion block 503 and the second expansion block 505 will expand toward the surroundings, thereby driving the arc expansion plate 501 to expand toward the four sides until the arc expansion plate 501 contacts the edge of the hole;

[0045] S3, and while the bidirectional threaded rod 3 rotates, it will drive the rotation of the cylindrical connecting block 902, thereby driving the rotation of the connecting rod 903, and then driving the third circular connecting block 901 to rotate, and the rotation of the third circular connecting block 901 will drive the conical barrel 904 to rotate, thereby driving the second circular connecting block 101 to rotate, and then driving the threaded rod 102 to rotate, and the rotation of the threaded rod 102 will drive the circular sliding block 103 to move downward along the threaded rod 102, thereby driving the rectangular sliding block 104 to move downward along the rectangular slide groove 106, and then driving the fixed rod 105 to expand to the surroundings until one end of the fixed rod 105 fits in the surrounding soil. When the fixed rod 105 fits in the soil, the second anchor rod placement block 502 set in the inner cavity of the third circular connecting block 901 corresponds to the first anchor rod placement block 8, and then the drive motor is removed;

[0046] S4. When the driving motor is removed, the lower end of the connecting mechanism 2 is connected to the bidirectional threaded rod 3 through a screw, and then the steel bar is inserted into the middle hole of the first anchor rod placement block 8, and then inserted from the first anchor rod placement block 8 into the middle hole of the second anchor rod placement block 502, so that the anchor rod is formed, and then the grouting machine is used to inject grout from the inner cavity of the connecting mechanism 2, and the slurry will flow to the inner cavity of the conical barrel 904 through the hollow structure of the bidirectional threaded rod 3, and the slurry in the inner cavity of the conical barrel 904 flows to the borehole through the slurry outlet hole 905 until the borehole is filled with slurry. After two hours of filling with cement slurry, a secondary high-pressure grouting operation is performed using a grouting machine, and the above grouting operation is repeated. After the grouting is completed, wait for the cement slurry to completely solidify, and then the two ends of the straightening belt 1 are sleeved in the circular grooves in the connecting mechanism 2, so as to fix and straighten the pipeline and end all operations.

[0047] Specifically, by spirally connecting the lower end of the connecting mechanism 2 with the bidirectional threaded rod 3, the straightening belt 1 can be replaced. If the straightening belt 1 is corroded by rainwater and microorganisms for a long time, the anti-floating and fixing effect of the straightening belt 1 will be weakened. At this time, it is only necessary to remove the connecting mechanism 2 and replace it with a new connecting mechanism 2. This will increase the service life of the anti-floating anchor and facilitate maintenance operations on the pipeline.

S2, when the first sliding assembly (4) and the second sliding assembly (6) move toward the middle of the bidirectional threaded rod (3), they drive one end of the first expansion block (503) and the second expansion block (505) to move toward the middle, so that the connection between the first expansion block (503) and the second expansion block (505) expands in a direction away from the bidirectional threaded rod, thereby driving the arc-shaped expansion plate (501) to expand in a direction away from the bidirectional threaded rod until the arc-shaped expansion plate (501) contacts the edge of the hole; S3, while the bidirectional threaded rod (3) rotates, it will drive the cylindrical connecting block (902) to rotate, thereby driving the connecting rod (903) to rotate, and then driving the third circular connecting block (901) to rotate, and the rotation of the third circular connecting block (901) will drive the conical barrel (904) to rotate, thereby driving the second circular connecting block (101) to rotate, and then driving the threaded rod (102) to rotate, and the rotation of the threaded rod (102) will drive the circular sliding block (103) to move downward along the threaded rod (102), thereby driving the rectangular sliding block (104) to move downward along the rectangular sliding groove (106), and then driving the fixed rod (105) to expand in all directions until one end of the fixed rod (105) fits in the surrounding soil. When the fixed rod (105) fits in the soil, the second anchor rod placement block (502) arranged in the inner cavity of the third circular connecting block (901) corresponds to the first anchor rod placement block (8), and then the drive motor is removed; S4. When the driving motor is removed, the lower end of the connecting mechanism (2) is connected to the bidirectional threaded rod (3) through a screw, and then the steel bar is inserted into the middle hole of the first anchor rod placement block (8), and then inserted from the first anchor rod placement block (8) into the middle hole of the second anchor rod placement block (502), so that the anchor rod is formed. Then, a grouting machine is used to inject grout from the inner cavity of the connecting mechanism (2), and the slurry will flow through the hollow structure of the bidirectional threaded rod (3) to the inner cavity of the conical barrel (904), and the slurry in the inner cavity of the conical barrel (904) will flow to the borehole through the slurry outlet hole (905) until the borehole is filled with slurry. After two hours of filling with cement slurry, a secondary high-pressure grouting operation is performed using a grouting machine, and the above grouting operation is repeated. After the grouting is completed, wait for the cement slurry to completely solidify, and then the two ends of the straightening belt (1) are sleeved into the circular grooves in the connecting mechanism (2), so as to fix and straighten the pipeline, and end all operations.
