Description

Technical Field

[0001] The present invention relates to the technical field of depth monitoring, and in particular to a system and method for monitoring the depth of a plastic drainage board. Background Art

[0002] In the actual engineering construction of soft foundation treatment, my country currently mainly uses a large number of plastic drain boards to enable the water in the soil to be slowly discharged under the load of the soft soil foundation, greatly reducing the porosity, thereby consolidating and deforming the foundation. This method has a fast consolidation speed and plays an irreplaceable role in shortening the construction period in the entire project. Plastic drain boards are designed with certain installation depth restrictions. During the construction process, a drain board depth monitoring system is required to detect the installation depth of the drain board, rather than determining the installation depth based on experience.

[0003] In the prior art, after the plastic drain board is inserted into the soft soil foundation, in order to facilitate the monitoring of the status of the plastic drain board underground, magnetic material is usually installed at the bottom of the plastic drain board, and then a magnetic detector is used to regularly detect the distance between the plastic drain board and the ground. However, since the plastic drain board is generally inserted into a soft soil foundation, the underground environment is relatively humid, the magnetic material is buried deep underground for a long time, and there is usually no protection for the magnetic material, which causes the magnetic material to be corroded by water molecules in the humid environment. The water molecules promote oxidation reactions on the surface of the magnetic material, resulting in degradation of its magnetic components, thereby reducing the magnetism of the material, and further making the depth of the plastic drain board detected by the magnetic detection equipment inaccurate, which can easily lead to the drainage system being unable to effectively drain water, resulting in water accumulation, thereby reducing the accuracy of the plastic drain board depth monitoring system.

[0004] Therefore, we propose a system and method for monitoring the depth of plastic drainage boards in order to solve the problems raised above. Summary of the invention

[0014] The method for monitoring the depth of a plastic drain board includes first connecting a positioning frame to an external crane device so that the positioning frame is perpendicular to the ground, passing one end of the plastic drain board mounted on the surface of a winding roller through a limiting groove, starting a hydraulic cylinder, connecting an anchor shoe to two mounting rods, thereby achieving a connection between the anchor shoe and the two mounting rods, and then fixing one end of the plastic drain board in a connecting hook, and then continuing the hydraulic cylinder to drive the magnetic strip to move underground, and simultaneously starting a magnetic detector to monitor the distance between the magnetic strip and the ground.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. During use, in order to prevent the influence of the humid underground environment on the magnetic strip in the depth detection equipment, when water molecules penetrate into the protective box, they are first absorbed by the sponge block. When the sponge block absorbs more water molecules, its own weight will increase, driving the support plate to rotate downward, and then the squeezing roller moves downward along the sponge block, thereby squeezing the sponge block, so that the water source enters the inside of the water tank along the support plate, effectively preventing the influence of the humid underground environment on the magnetic strip in the depth monitoring equipment, and solving the problem in the prior art that the magnetic material used as the plastic drain board for depth monitoring is easily corroded by the humid underground environment, resulting in inaccurate detection results.

[0018] 2. During use, during the installation of the plastic drain board, in order to prevent the plastic drain board from shifting during the descent process, when one end of the plastic drain board moves underground, insert the telescopic rod into the inside of the connecting shaft to rotate the positioning wheel, and then roll up the scale line with digital scale. When the plastic drain board descends to a certain depth, you can use the parallel ruler to check the scale of the scale line parallel to it, and then calculate the length of the descending plastic drain board. When the length of the descending plastic drain board is consistent with the depth detected by the magnetic detector, it means that the descent process of the plastic drain board is relatively smooth, which effectively prevents the plastic drain board from breaking during the process of being buried deep underground.

[0019] 3. During use, after the scale line detection is completed, separate the telescopic rod from the connecting shaft so that the coil spring is no longer affected by the tension, driving the roller to rotate in the opposite direction, completing the automatic recovery of the scale line, and facilitating the later measurement of the depth of the plastic drain board.

Both ends of the two clamping rods 705 are movable and penetrate the inside of the two positioning grooves 703. A connecting hook 8 is provided near the center of the top of the anchor shoe 701.

[0038] Working principle of this embodiment: in the actual engineering construction of soft foundation treatment, in order to drain groundwater, first connect the positioning frame 1 with the external crane equipment, so that the positioning frame 1 is vertical to the ground, start the hydraulic cylinder 3 to extend it, drive the lifting rod 4 to move downward, and then pass one end of the plastic drainage board sleeved on the surface of the winding roller 604 through the limiting groove 5 and move to the bottom end of the lifting rod 4, and then move the anchor shoe 701 to the bottom end of the lifting rod 4, so that the two positioning grooves 703 are aligned with the bottom ends of the two mounting rods 702, and then move the anchor shoe 701 upward, so that the two mounting rods 702 are respectively inserted into the inside of the two positioning grooves 703, and then start the two bidirectional electric push rods 704 to extend them respectively, drive the two clamping rods 705 to move to the outside of the two mounting rods 702 respectively, so that the four clamping rods 705 are respectively embedded in the inside of the two positioning grooves 703, whereby Fig. 9As shown, the internal cross-section of the positioning groove 703 is T-shaped, and its purpose is to limit the two clamping rods 705, thereby realizing the connection between the anchor shoe 701 and the two mounting rods 702, and then one end of the plastic drain board can be fixed on the outer surface of the connecting hook 8, that is, the connection between the plastic drain board and the anchor shoe 701 is realized, and then the hydraulic cylinder 3 is started to drive the anchor shoe 701 and one end of the plastic drain board to move underground, thereby driving the magnetic strip 903 to move underground, and at the same time starting the magnetic detector 11 to monitor the distance between the magnetic strip 903 and the ground, and then detecting the distance between the bottom end of the plastic drain board and the ground. When the magnetic detector 11 detects that the distance between the magnetic strip 903 and the ground reaches the depth that the plastic drain board needs to be lowered , the hydraulic cylinder 3 can be closed, and at the same time, the two bidirectional electric push rods 704 are started to shorten them, driving the four clamping rods 705 to move to the inside of the two installation rods 702 respectively, and then the hydraulic cylinder 3 is started again to shorten them, which can drive the two installation rods 702 to move upward, thereby separating the two installation rods 702 from the anchor shoes 701, and then the two installation rods 702 can be brought back to the ground, and the ground part of the plastic drain board can be cut off by an external shearing device, thus completing the installation of the plastic drain board. In order to prevent the plastic drain board from deflecting during the descent process, when one end of the plastic drain board moves underground, the hydraulic rod 612 is started to extend it, driving the telescopic rod 613 to move forward, thereby inserting it into the inner part of the connecting shaft 607. When one end of the plastic drain board moves downward, it drives the two rotating shafts 603 to rotate, and then drives the winding roller 604 to rotate, so that the plastic drain board is released outward. At the same time, the rotating shaft 603 drives the driving gear 605 to rotate during the rotation, and then drives the driven gear 608 to rotate, so that the positioning wheel 610 rotates, and then the scale line 618 with a digital scale is rolled up, wherein the scale line 618 also drives the roller 615 to rotate during the upward winding process, so that the winding spring 617 is tightened. When the plastic drain board drops to a certain depth, the scale of the scale line 618 parallel to it can be checked through the parallel ruler 619, and then the length of the dropped plastic drain board can be converted. When the length of the dropped plastic drain board is equal to the magnetic When the depth detected by the force detector 11 is consistent, it means that the plastic drain board descends smoothly without any belt breakage. The cooperation between the measuring component 6 and the protective component 9 can effectively prevent the plastic drain board from being broken when buried deep underground. Then the hydraulic rod 612 is started to extend, driving the telescopic rod 613 to move toward the inside of the installation groove 611, thereby realizing the separation between the telescopic rod 613 and the connecting shaft 607, so that the coil spring 617 is no longer affected by the tension and can be extended under the action of its own elastic force, thereby driving the roller 615 to rotate in the opposite direction, and then the scale line 618 set on the surface of the positioning wheel 610 is rolled up again, completing the automatic recovery of the scale line 618.It is convenient to measure the depth of the plastic drainage board in the later stage. In order to monitor whether the plastic drainage pipe buried deep underground will be offset due to environmental influences, the magnetic strip 903 is first placed inside the protective box 901, so that the staff can detect the distance between the anchor shoes 701 through the magnetic detector 11, wherein the magnetic detector 11 can sense the surrounding magnetic field strength. As the distance between the detector and the magnetic strip 903 increases, the detected magnetic field strength will weaken. By measuring the change in magnetic field strength, the detector can estimate the distance from the magnetic strip 903. In addition, the magnetic detector 11 uses selective frequency modulation technology and can work at a specific frequency to specifically look for the signal of the target magnetic strip 903. Other signals will not be received by the detector due to different frequencies, thereby reducing interference. In order to prevent water molecules in the humid environment underground from affecting the magnetic strip 903, 03, when the surrounding environment of the buried magnetic strip 903 is relatively humid and penetrates into the protective box 901, the water molecules are first absorbed by the sponge block 910, wherein in the sealed space, the water molecules will diffuse to the surface of the sponge block 910, especially when the humidity in the space is high, the water absorption performance of the sponge block 910 makes the surrounding water molecules constantly attracted and enter the pores, thereby absorbing the water vapor in the protective box 901, when the sponge block 910 absorbs more water molecules, its own weight will increase, thereby increasing the weight of the support plate 905, thereby driving the support plate 905 to rotate in the direction of the first spring 914, thereby causing the multiple first springs 914 to be squeezed and shortened, and when the support plate 905 rotates to a downwardly inclined position, the squeezing roller 909 moves downward along the support plate 905 under the action of its own gravity, wherein, Fig.11 As shown, the slide groove 906 limits the slider 907, so that the squeezing roller 909 moves more smoothly. The movement of the squeezing roller 909 squeezes the expanded sponge block 910, thereby squeezing out the water inside the sponge block 910. The water source flows downward along the support plate 905. At the same time, the squeezing rod 911 is also driven to rotate downward during the downward rotation of the support plate 905. Fig.13 As shown, the cross section of the squeezing rod 911 is T-shaped, and its purpose is to squeeze the pressing plate 919, so that the pressing plate 919 moves downward under the influence of pressure, thereby driving the sealing cover 920 to move downward. When the sealing cover 920 moves downward to a position away from the smaller inner diameter of the water tank 916, the water tank 916 can be opened. At this time, the water outlet end of the squeezing rod 911 is just aligned with the top of the water tank 916, so that the water squeezed out from the sponge block 910 can be moved to the inside of the water tank 916, effectively preventing the protective box 901 from entering the water vapor and affecting the performance of the magnetic strip 903. When the water source in the sponge block 910 flows into the water tank 916, the weight of the support plate 905 is reduced, and the multiple first springs 914 are all extended under the action of their own elastic force, thereby driving the support plate 905 to rotate in the opposite direction until it is reset. Fig.10As shown, the support plate 905 is arranged at an angle, so when the support plate 905 is reset, the squeezing roller 909 can also be reset under the action of its own gravity. At the same time, the reset of the support plate 905 drives the squeezing rod 911 to reset, so that the multiple second springs 918 are no longer squeezed and extend under the action of their own elastic force, thereby driving the pressing plate 919 and the sealing cover 920 to move upward, thereby sealing the inside of the water tank 916 to prevent water vapor from flowing back to the inside of the protective box 901 to corrode the magnetic strip 903. Among them, the protective cover 902 is made of metal iron material. Because iron has good magnetism and magnetic conductivity, these characteristics enable iron to effectively shield the influence of external magnetic field on the magnetic strip 903. Through the action of the protective component 9, the influence of the underground humid environment on the magnetic strip 903 in the depth monitoring equipment is effectively prevented. Through the protection of the magnetic strip 903, the accuracy of the plastic drain board depth monitoring equipment is further improved, and the problem that the magnetic material used as the plastic drain board depth detection in the prior art is easily corroded by the underground humid environment is solved.

[0039] Embodiment 2: According to Figure 1-13 As shown, the method for monitoring the depth of the plastic drain board includes: firstly, connecting the positioning frame 1 to the external crane equipment so that the positioning frame 1 is perpendicular to the ground, passing one end of the plastic drain board mounted on the surface of the winding roller 604 through the limiting groove 5, starting the hydraulic cylinder 3, connecting the anchor shoe 701 with the two mounting rods 702, thereby realizing the connection between the anchor shoe 701 and the two mounting rods 702, and then fixing one end of the plastic drain board in the connecting hook 8, and then continuing to start the hydraulic cylinder 3 to drive the magnetic strip 903 to move underground, and at the same time starting the magnetic detector 11 to monitor the distance between the magnetic strip 903 and the ground. When the plastic drain board drops to the required depth, the installation of the plastic drain board is completed. When one end of the plastic drain board moves underground, the telescopic rod 613 is inserted into the interior of the connecting shaft 607, so that the positioning wheel 610 rotates, and then Roll up the scale line 618 with digital scale. When the plastic drain board descends to a certain depth, the scale of the scale line 618 in parallel with it can be checked through the parallel ruler 619, and then the length of the descending plastic drain board can be converted. When the environment around the magnetic strip 903 buried deep underground is relatively humid and penetrates into the protective box 901, the water molecules are first absorbed by the sponge block 910. When the sponge block 910 absorbs more water molecules, its own weight will increase, driving the support plate 905 to rotate in the direction of the first spring 914, so that the squeezing roller 909 moves downward along the support plate 905 under the action of its own gravity, so that the expanded sponge block 910 is squeezed, thereby squeezing out the water inside it, and the water source flows downward along the support plate 905 and enters the inside of the water tank 916, preventing the protective box 901 from entering water vapor and affecting the performance of the magnetic strip 903.

[0040] Working principle of this embodiment: In order to drain groundwater, first connect the positioning frame 1 to the external crane equipment so that the positioning frame 1 is perpendicular to the ground, then pass one end of the plastic drainage board mounted on the surface of the winding roller 604 through the limiting groove 5 and fix it on the outer surface of the connecting hook 8, move the anchor shoe 701 to the bottom end of the lifting rod 4, so that the two positioning grooves 703 are aligned with the bottom ends of the two mounting rods 702, and then move the anchor shoe 701 upward, so that the two mounting rods 702 are respectively inserted into the inside of the two positioning grooves 703, start the two bidirectional electric push rods 704, and extend them respectively, so that the four clamping rods 705 are respectively embedded in the inside of the two positioning grooves 703, and then the hydraulic cylinder 3 drives the anchor shoe 701 and one end of the plastic drainage board to the underground The magnetic strip 903 is moved underground, and the magnetic detector 11 is started at the same time to monitor the distance between the magnetic strip 903 and the ground, and then the distance between the bottom end of the plastic drainage board and the ground is detected. When the magnetic detector 11 detects that the distance between the magnetic strip 903 and the ground reaches the depth that the plastic drainage board needs to be lowered, the hydraulic cylinder 3 can be closed, and at the same time, the two bidirectional electric push rods 704 are started to shorten, driving the four clamping rods 705 to move to the inside of the two installation rods 702 respectively, and then the hydraulic cylinder 3 is started again to shorten it, which can drive the two installation rods 702 to move upward, so that the two installation rods 702 are separated from the anchor shoe 701, and then the two installation rods 702 can be brought back to the ground, and the plastic drainage board can be sheared off by an external shearing device. When the ground part of the water board is cut off, the installation of the plastic drain board is completed. When one end of the plastic drain board moves underground, the hydraulic rod 612 is started to insert the telescopic rod 613 into the interior of the connecting shaft 607, thereby driving the rotating shaft 603 to rotate. At the same time, the rotating shaft 603 rotates and drives the driving gear 605 to rotate, thereby driving the driven gear 608 to rotate, so that the positioning wheel 610 rotates, and then the scale line 618 with a digital scale is rolled up. When the plastic drain board drops to a certain depth, the parallel ruler 619 can be used to check the scale of the scale line 618 parallel to it, and then the length of the dropped plastic drain board can be converted. When the length of the dropped plastic drain board is consistent with the depth detected by the magnetic detector 11, When the magnetic strip 903 is buried underground and the surrounding environment is relatively humid, it means that the plastic drainage board descends smoothly without breaking. When the magnetic strip 903 is buried underground and the surrounding environment is relatively humid, it penetrates into the protective box 901. The water molecules are first absorbed by the sponge block 910. In the sealed space, the water molecules will diffuse to the surface of the sponge block 910. Especially when the humidity in the space is high, the water absorption performance of the sponge block 910 makes the surrounding water molecules constantly attracted and enter the pores, thereby absorbing the water vapor in the protective box 901. When the sponge block 910 absorbs more water molecules, its own weight will increase, thereby increasing the weight of the support plate 905, thereby driving the support plate 905 to rotate in the direction of the first spring 914, thereby causing the multiple first springs 914 to be squeezed and shortened.When the support plate 905 rotates to a downwardly inclined position, the squeezing roller 909 moves downward along the support plate 905 under its own gravity, thereby squeezing out the water inside it, and the water source flows downward along the support plate 905. At the same time, the squeezing rod 911 is also driven to rotate downward during the downward rotation of the support plate 905 and enter the water tank 916, thereby preventing the underground humid environment from affecting the magnetic strip 903 in the depth monitoring device.

[0041] In the present invention, in order to drain groundwater from a soft foundation, the positioning frame 1 is first connected to an external crane device so that the positioning frame 1 is perpendicular to the ground, the hydraulic cylinder 3 is started to extend it, and the lifting rod 4 is driven to move downward, and then one end of the plastic drainage plate sleeved on the surface of the winding roller 604 is passed through the limiting groove 5 and moved to the bottom end of the lifting rod 4, and then the anchor shoe 701 is moved to the bottom end of the lifting rod 4 so that the two positioning grooves 703 are aligned with the bottom ends of the two mounting rods 702, and then the anchor shoe 701 is moved upward, so that the two mounting rods 702 are respectively inserted into the inside of the two positioning grooves 703, and then the two bidirectional electric push rods 704 are started to extend them respectively, driving the two clamping rods 705 to move to the outside of the two mounting rods 702 respectively, so that the four The two clamping rods 705 are respectively embedded in the two positioning grooves 703 to realize the connection between the anchor shoe 701 and the two mounting rods 702. Then, one end of the plastic drain board can be fixed on the outer surface of the connecting hook 8, that is, the connection between the plastic drain board and the anchor shoe 701 is realized. Then, the hydraulic cylinder 3 is started to drive the anchor shoe 701 and one end of the plastic drain board to move underground, thereby driving the magnetic strip 903 to move underground, and at the same time, the magnetic detector 11 is started to monitor the distance between the magnetic strip 903 and the ground, thereby detecting the distance between the bottom end of the plastic drain board and the ground. When the magnetic detector 11 detects that the distance between the magnetic strip 903 and the ground reaches the depth that the plastic drain board needs to be lowered, the hydraulic cylinder 3 can be closed, and at the same time, the two bidirectional electric push rods 7 are started. 04, shorten it, drive the four clamping rods 705 to move to the inside of the two installation rods 702 respectively, and then start the hydraulic cylinder 3 again to shorten it, which can drive the two installation rods 702 to move upward, so that the two installation rods 702 are separated from the anchor shoe 701, and then the two installation rods 702 can be brought back to the ground, and the ground part of the plastic drain board is cut off by an external shearing device, and the installation of the plastic drain board is completed. When one end of the plastic drain board moves underground, start the hydraulic rod 612 to extend it, drive the telescopic rod 613 to move forward, so that it is inserted into the inside of the connecting shaft 607, and when one end of the plastic drain board moves downward, it drives the two rotating shafts 603 to rotate, and then drives the winding roller 604 to rotate, so that the plastic drain board When the plastic drain board is lowered to a certain depth, the scale line 618 in parallel with the plastic drain board can be checked through the parallel ruler 619, and the length of the lowered plastic drain board can be calculated. When the length of the lowered plastic drain board is consistent with the depth detected by the magnetic detector 11, it means that the lowering process of the plastic drain board is relatively smooth and there is no belt breakage. Then the hydraulic rod 612 is started,The extension rod 613 is driven to move toward the inside of the installation groove 611, thereby realizing the separation between the extension rod 613 and the connecting shaft 607, so that the coil spring 617 is no longer affected by the tension and can be stretched under the action of its own elastic force, thereby driving the roller 615 to rotate in the opposite direction, and then the scale line 618 sleeved on the surface of the positioning wheel 610 is rolled up again, completing the automatic recovery of the scale line 618. In order to monitor whether the plastic drainage pipe buried deep underground will be deviated due to the influence of the environment, firstly, the magnetic strip 903 is placed inside the protective box 901 to prevent the water molecules in the humid environment underground from corroding the magnetic strip 903. When the surrounding environment of the buried magnetic strip 903 is relatively humid and penetrates into the protective box 901, the water molecules are first absorbed by the sponge block 910. When the sponge block 910 absorbs more water molecules, its own weight will increase, thereby increasing the weight of the support plate 905, thereby driving the support plate 905 to rotate in the direction of the first spring 914, thereby causing the multiple first springs 914 to be squeezed and shortened. When the support plate 905 rotates to a downwardly inclined position, the squeezing roller 909 moves downward along the support plate 905 under the action of its own gravity. The movement of the squeezing roller 909 squeezes the expanded sponge block 910, thereby squeezing the sponge block 910 inside. The water is squeezed out, and the water source flows downward along the support plate 905. At the same time, the support plate 905 also drives the squeezing rod 911 to rotate downward during its downward rotation, so that the pressing plate 919 moves downward under the influence of pressure, thereby driving the sealing cover 920 to move downward. When the sealing cover 920 moves downward to a position away from the smaller inner diameter of the water tank 916, the water tank 916 can be opened. At this time, the water outlet end of the squeezing rod 911 is just aligned with the top of the water tank 916, and the water squeezed out from the sponge block 910 can be moved to the inside of the water tank 916, effectively preventing the protective box 901 from entering the water vapor and affecting the performance of the magnetic strip 903. After the water source flows into the water tank 916, the weight of the support plate 905 is reduced, and the multiple first springs 914 are stretched under their own elastic force, thereby driving the support plate 905 to rotate in the opposite direction until it is reset. When the support plate 905 is reset, the squeezing roller 909 can also be reset under its own gravity. At the same time, the reset of the support plate 905 drives the squeezing rod 911 to reset, so that the multiple second springs 918 are no longer squeezed and stretch under their own elastic force, thereby driving the pressing plate 919 and the sealing cover 920 to move upward, thereby sealing the inside of the water tank 916 to prevent water vapor from flowing back to the inside of the protective box 901 and corroding the magnetic strip 903.
