Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of drainage, and particularly relates to a method and device for dredging and removing silt from a seepage drainage pipe. Background Art
[0002] In large-scale tailing dams at high latitudes, the drainage system determines the height of the dam body's phreatic line. If the phreatic line rises during the flood season, it will have a significant impact on the safety of the entire dam body. The seepage drainage pipe, as part of the drainage system, acts as a role in discharging groundwater. If the geotextile around it is blocked by fine particles, groundwater cannot be effectively discharged. In a large-scale model, the arc-shaped seepage drainage pipe may reach nearly 100 meters, and it is difficult to determine the siltation position. Even if the position is determined, it is also difficult to complete the dredging work at this position. Summary of the Invention
[0003] The present invention provides a method and device for dredging and removing silt from a seepage drainage pipe, aiming to solve the problem that it is difficult to position the siltation position of the seepage drainage pipe and it is difficult to carry out targeted silt removal.
[0004] To achieve the above purpose, an embodiment of the present invention provides a method for dredging and removing silt from a seepage drainage pipe, including:
[0005] S10. A number of vibration units are arranged along the axial direction of the seepage drainage pipe, and laser units are arranged between adjacent vibration units. The laser units emit and receive reflected laser along the radial direction of the seepage drainage pipe;
[0006] S20. The laser units emit laser at a preset power and receive the standard light intensity. The standard light intensity is the light intensity of the reflected laser when the drainage is smooth;
[0007] S30. Each laser unit emits laser at a preset power and obtains the real-time monitored light intensity of each laser unit;
[0008] S40. Compare the monitored light intensity of each laser unit with the standard light intensity one by one from upstream to downstream. If the monitored light intensity of any one is greater than the standard light intensity, locate the laser unit that receives the monitored light intensity and start the vibration unit closest to the upstream of the laser unit that receives the monitored light intensity to vibrate. When the monitored light intensity decreases to the same as the standard light intensity, turn off the vibration unit.
[0009] Preferably, at most one vibration unit vibrates simultaneously.
[0010] The present application also provides a device for dredging and removing silt from a seepage drainage pipe, which is applied to the aforementioned method for dredging and removing silt from a seepage drainage pipe.

[0013] Preferably, the vibration unit is an ultrasonic vibration ring.
[0014] Preferably, the device for dredging and removing stasis from the infiltration and drainage pipe further includes a first wire conduit and a second wire conduit.

[0025] To make the technical problems, technical solutions, and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.
[0026] As Figures 1 - 3 shown, an embodiment of the present invention provides a method for dredging a seepage drainage pipe, including the following steps:
[0027] S10. A plurality of vibration units 2 are arranged along the axial direction of the seepage drainage pipe 1, and a laser unit 3 is arranged between adjacent vibration units 2. The laser unit 3 emits and receives reflected laser along the radial direction of the seepage drainage pipe 1.
[0028] A plurality of vibration units 2 are arranged along the length direction of the seepage drainage pipe 1. The vibration units 2 are arranged outside the side wall of the seepage drainage pipe 1, and the adjacent vibration units 2 are spaced at the same interval. In this embodiment, the interval between adjacent vibration units 2 is 100 m. A laser unit 3 is also arranged between any two adjacent vibration units 2. The laser unit 3 is arranged inside the side wall of the seepage drainage pipe 1. The laser unit 3 is preferably riveted to the seepage drainage pipe 1 to avoid falling off due to water flow impact. The laser unit 3 can emit and receive laser. In this application, the laser unit 3 emits laser along the radius direction of the seepage drainage pipe 1, and the laser is reflected by the side wall of the seepage drainage pipe 1 and then received by the laser unit 3 again. Preferably, the laser unit 3 is at the same distance from two adjacent vibration units 2, that is, the laser unit 3 is arranged at the midpoint between two adjacent vibration units 2. Each laser unit 3 and vibration unit 2 are numbered in sequence.
[0029] S20. The laser unit 3 emits laser at a preset power and receives the reflected laser to obtain the marked light intensity. The standard light intensity is the light intensity of the reflected laser when the drainage is smooth.
[0030] The laser unit 3 emits laser at a predetermined power when the drainage is smooth, and receives the reflected laser and analyzes the laser to obtain the standard light intensity. When the laser reflected by each laser unit 3 is the standard light intensity, it can be inferred that the drainage is smooth here and there is no blockage.
[0031] S30. Each laser unit 3 emits laser at a preset power and obtains the real-time monitored light intensity of each laser unit 3.
[0032] In the monitoring state, each laser unit 3 continuously emits laser at a preset power, and obtains the real-time monitored light intensity of each laser unit 3.
[0033] S40. Compare the monitored light intensity of each laser unit 3 with the standard light intensity one by one from upstream to downstream. If the monitored light intensity of any one is greater than the standard light intensity, locate the laser unit 3 that receives the monitored light intensity and start the vibration of the nearest vibration unit 2 upstream of the laser unit 3 that receives the monitored light intensity. When the monitored light intensity decreases to the same as the standard light intensity, turn off the vibration unit 2.
[0034] In step S40, the monitoring light intensity obtained by each laser unit 3 is compared with the standard light intensity one by one along the flow direction of the water flow in the infiltration and drainage pipe 1. When the water flow in the infiltration and drainage pipe 1 is smooth, the soil particles in the soil can flow into the infiltration and drainage pipe 1 along with the groundwater, and the water flow rate is relatively large and the reflected light intensity is weak. Therefore, the monitoring light intensity obtained by the laser unit 3 is the same as or close to the standard light intensity. When congestion occurs in the infiltration and drainage pipe 1, it is difficult for the geotextile around the infiltration and drainage pipe 1 to drain the groundwater in the soil into the infiltration and drainage pipe 1 due to blockage, and the flow rate in the infiltration and drainage pipe 1 becomes smaller, resulting in an increase in the laser light intensity, and thus an increase in the light intensity after laser reflection. Based on this, it is possible to know whether the geotextile is blocked at the filter holes through the change in the light intensity after laser reflection.
[0035] During the process of comparing one by one from upstream to downstream, when it is found that the monitoring light intensity received by any laser unit 3 is greater than the standard light intensity, it indicates that blockage has occurred at the location where the laser unit 3 is located. At this time, the location of this laser unit 3 is located to obtain its position on the infiltration and drainage pipe 1, which is convenient for confirming the blockage location. After obtaining the position of this laser unit 3, the vibration unit 2 closest to the upstream of the laser unit 3 with a monitoring light intensity greater than the standard light intensity is activated to vibrate, so that the infiltration and drainage pipe 1 and the geotextile attached to the outer wall of the infiltration and drainage pipe 1 vibrate, and the silt blocked on the geotextile falls off. As the silt falls off, the soil particles in the soil can flow into the infiltration and drainage pipe 1 again along with the groundwater, and the monitoring light intensity gradually decreases. When the monitoring light intensity decreases to the same as the standard light intensity, it indicates that the location where the laser unit 3 with an increased monitoring light intensity is located has completed silt removal.
[0036] According to the content of the above step S40, the monitoring light intensity monitored by each laser unit 3 is compared one by one. When multiple vibration units 2 need to vibrate, at most one vibration unit 2 vibrates, and the multiple vibration units 2 vibrate sequentially from top to bottom.
[0037] To better explain this solution, it is assumed that there are three vibration units 2, which are the first vibration unit, the second vibration unit, and the third vibration unit in sequence from top to bottom; there are three laser units 3, which are the first laser unit, the second laser unit, and the third laser unit in sequence from top to bottom. The first laser unit is arranged between the first vibration unit and the second vibration unit, the second laser unit is arranged between the second vibration unit and the third vibration unit, and the third laser unit is arranged below the third vibration unit.
[0038] The first laser unit obtains the monitored light intensity and compares it with the standard light intensity. When the monitored light intensity obtained by the first laser unit is greater than the standard light intensity, the nearest vibration unit 2 above it, i.e., the first vibration unit, is activated to vibrate. With the vibration of the first vibration unit, the silt in the area near the upper part of the first laser unit is shaken off, and the groundwater in the soil can continue to enter the drain pipe 1. At this time, the monitored light intensity received by the first laser unit gradually decreases. When the monitored light intensity of the first receiving unit decreases to the standard light intensity, it is considered that the dredging of the drain pipe 1 is completed, and the first vibration unit is turned off. If the monitored light intensity is the same as or approximately similar to the standard light intensity, it is considered that the drain pipe 1 is not blocked, and the monitored light intensity of the second laser unit is directly obtained and compared with the standard light intensity.
[0039] Obtain the monitored light intensity of the second laser unit, compare it with the standard light intensity again, and repeat the comparison process of the first laser unit.
[0040] This application also provides a device applied to the aforementioned method for dredging and removing silt from the drain pipe, including:
[0041] The laser unit 3 is arranged on the inner wall of the drain pipe 1, and the laser unit 3 faces the central axis of the drain pipe 1. The laser unit 3 emits and receives the reflected laser along the radial direction of the drain pipe 1;
[0042] The vibration unit 2 is arranged on the outer wall of the drain pipe 1 and is used to vibrate the drain pipe 1 and the geotextile outside the drain pipe 1.
[0043] A number of filter holes are arranged on the side wall of the aforementioned drain pipe 1. The outer wall of the drain pipe 1 is also wrapped with a geotextile. The geotextile shields the filter holes on the outer wall of the drain pipe 1. The geotextile is located between the drain pipe 1 and the vibration device. Therefore, when the vibration device applies vibration to the drain pipe 1, the geotextile on the drain pipe 1 vibrates simultaneously, and the silt attached to the geotextile falls off, enabling soil particles to enter the drain pipe 1.
[0044] Preferably, the vibration unit 2 is sleeved outside the drain pipe 1 so that the vibration unit 2 can act vertically on the side wall of the drain pipe 1. The laser unit 3 emits laser along the radial direction of the drain pipe 1, perpendicular to the water flow flowing axially in the drain pipe 1, reducing the error caused by the water entry angle.
[0045] Preferably, the device for dredging and removing silt from the drain pipe further includes a first wire conduit 4 and a second wire conduit 5. The first wire conduit 4 and the second wire conduit 5 are arranged side by side with the drain pipe 1, and the length directions of the first wire conduit 4 and the second wire conduit 5 are the same as the length direction of the drain pipe 1. The first wire conduit 4 is used to accommodate the wires of the vibration unit 2, and the second wire conduit 5 is used to accommodate the wires of the laser unit 3.
[0046] Preferably, in the present application, the shape of the filter holes is plum blossom-shaped, which is beneficial to preventing sediment, impurities or particulate matter from accumulating at the filter holes. Moreover, the plum blossom-shaped hole layout has a more uniform stress distribution and will not cause a large local stress concentration on the drain pipe 1, thus maintaining the overall strength of the pipe. A number of filter holes are arranged in a matrix, which helps to improve the drainage efficiency and increase the drainage area.
[0047] The device for dredging and removing silt from the drain pipe further includes a control unit, which is signal-connected to the vibration unit 2 and the laser unit 3. The control unit has the functions of recording, comparing, instructing and displaying. The standard light intensity is stored in the control unit as the average value after multiple tests. After the control unit obtains the monitored light intensity obtained by each laser unit 3, the comparison is completed in the control unit. According to the comparison result, different instructions are issued to command the corresponding vibration unit 2 to vibrate, and the position of the blockage is displayed by showing the number of the laser unit 3.
[0048] The method and device for dredging and removing silt from the drain pipe provided in the present application are not limited to the shape of the drain pipe 1 and can be applied to drain pipes 1 with linear, curved and other shapes. Moreover, it judges whether the filter holes of the drain pipe 1 are blocked based on the change in the light intensity of the laser unit 3 and automatically dredges according to the blockage result. The present application is suitable for being arranged in service buildings with long drain pipes 1, such as large-scale tailing dams, slopes around dams and systems with larger diameters of drain pipes 1. The method and device can also act on drain pipes 1 buried deeper and extending farther into the soil body, achieving the effects of non-destructive monitoring and positioning of blockages, and reducing the difficulty of finding the blockage position and dredging.
[0049] The above is the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
