Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a method for quickly controlling riverbank piping. Background Art

[0002] Since pipe bursts are not easy to detect in their early stages, on the inner side of the river bank, the flood is turbid, the water is fast and the waves are high, making it difficult to tell whether the water surface is a vortex formed by floating objects or a vortex caused by pipe bursts. On the outer side of the river bank, there are usually planted crops or grass and bushes, and there may also be stagnant water. The pipe burst outlet is tightly obscured and difficult to find, and it is even more difficult to find at night. By the time it is discovered, it is often too late and the dam burst is difficult to prevent.

[0003] There are many existing methods for treating pipe bursts, for example: Document No. CN1320744A discloses a method for quickly plugging leaks in flood control dams and pipe bursts, in which a hose that can be inflated by air or water is inserted into the leak, and the leak is plugged after being inflated by air or water; Document No. CN104005418A discloses a method for quickly dealing with underground pipe bursts, in which a surrounding well filtration and drainage system is built where pipe bursts are found, and the gushing water at the pipe burst point is guided to the surrounding well filtration and drainage system for discharge, and then a steel plate is used to stop water; Document No. CN106836129A discloses a method for dealing with pipe bursts, in which a pipe burst hole is opened and a pipe is formed. In the upper part, a hollow steel casing is driven into the soil to a certain depth with a vibrating hammer, and filter materials composed of coarse sand, graded crushed stone and block stones are filled in the hollow steel casing from bottom to top in layers; the document with publication number CN106906795B discloses an elastic plugging container and a pipe burst plugging method, by filling gas into the body to enlarge the body and fill multiple elastic protrusions, the elastic plugging container is fixed in the pipe burst channel to achieve a plugging effect; the document with publication number CN110761309B discloses an emergency drainage and construction method for pipe bursts, a drainage pipe composed of a sealing pipe, an adjustment pipe and multiple filter pipes, and drainage treatment is performed on the pipe burst outlet. Although the above-mentioned prior art discloses certain pipe burst blocking solutions, it does not point out how to find the pipe burst point from the source and how to implement blocking. As for the search for pipe burst points on riverbanks, the document with the publication number CN113537141A discloses a rapid detection method and system for pipe bursts and landslides in dams. By acquiring the point cloud data of the dam in the area to be detected, the feature points of the point cloud data are extracted to obtain edge feature points, and the location of the pipe burst or landslide is determined. However, as mentioned above, if the outside of the dam is the slope of the dam itself and it is bright, it may be found during the day, but if the area to be checked is covered by dense vegetation, the method will completely fail. Moreover, the location of the pipe burst water inlet cannot be found, and the success rate of water blocking is very low. Therefore, early detection of the location of the pipe burst water inlet and outlet and early control of the pipe burst can resolve major risks. Finding a method for early detection of pipe bursts is the key to successful rescue. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a method for quickly controlling riverbank pipe bursts, which can quickly discover and determine the pipe burst inlet and pipe burst outlet, and effectively block the pipe burst by first blocking the pipe burst inlet and then blocking the pipe burst channel and outlet.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A method for quickly controlling riverbank piping, comprising the following steps:

[0007] S1. In the key river sections with pipe bursts on the river bank, multiple pipe burst detection units are divided at certain intervals along the water flow direction within a certain range along the inner edge of the river bank. A hub is installed in each pipe burst detection unit. The hub is driven by a micro motor. Colored balloons are tied to the hub through thin ropes to make the colored balloons drift in the water.

[0008] S2. When a vortex appears in a pipe burst detection unit, determine whether a pipe burst has occurred based on the movement state of the vortex.

[0009] S3. When it is determined that a pipe burst has occurred, the wheel hub is rotated and the colored balloon is towed by a thin rope. At the same time, a drone is used to fly back and forth along the pipe burst inspection unit parallel to the river bank to shoot the drift of the colored balloon and simultaneously transmit the video back to the monitoring screen. When the colored balloon is found to be rotating or being sucked underwater, the coordinates are immediately locked and marked as the pipe burst inlet.

[0010] S4. Insert one end of a plastic hose into the paint bucket, and insert the other end of the plastic hose into the pipe inlet, and inject paint water into the pipe channel; at the same time, connect one end of the carbon dioxide gas cylinder to the gas outlet with a hose, and insert the other end of the hose into the pipe inlet, open the cylinder valve, and inject carbon dioxide gas into the pipe channel.

[0011] S5. Look for the pipe burst outlet on the outside of the river bank, perpendicular to the pipe burst point and on the ground covered with vegetation. Use a gas collecting bottle with a vacuum pump to collect gas. Connect the gas collecting bottle to a glass cup filled with lime water with a soft rubber tube. When the lime water becomes turbid, it indicates that carbon dioxide gas has overflowed. When the vegetation is turned over, pigment water seepage points are found. Mark the pigment water seepage points as pipe burst outlets.

[0012] S6. Select the size of the prefabricated waterproof blanket according to the size of the piping channel, dig a trench around the piping inlet, install the waterproof blanket at the piping inlet and fix the waterproof blanket in the trench.

[0013] S7. Stop the sand-blowing ship near the piping point, and blow sand underwater with the piping point as the center to cover the waterproof blanket with sand, and then throw stones on the sand to cover it.

[0014] S8. Seal the pipe burst channel at the pipe burst outlet.

[0015] Furthermore, when deploying colored balloons, a column is installed on the upstream side of each pipe burst inspection unit, a rotating shaft is installed on the column, more than three hubs are installed on the rotating shaft, the hubs are divided into no less than three grids by partitions, a 60m-110m long thin rope is wrapped around each grid hub, and no less than one colored balloon is tied to the end of the thin rope.

[0016] Furthermore, when identifying whether a pipe burst has occurred, if the vortex follows the floating object and moves downstream, it is identified as a vortex caused by the obstruction of the floating object; if the vortex produces backwash waves, it is identified as a vortex caused by an obstacle in the river channel; if the position of the vortex is fixed, the vortex is relatively round and the center of the vortex is sunken, it is identified as a vortex caused by a pipe burst.

[0017] Furthermore, when making the waterproof blanket, a waterproof material with a thickness of 2mm-5mm is used. The waterproof blanket is cut into a square and the four corners of the waterproof blanket are cut off. A cloth tube is sewn on each side of the waterproof blanket, and a steel bar is inserted into the cloth tube and sunk into the groove to fix the waterproof blanket. Finally, hemp rope is tied at the four corners of the waterproof blanket.

[0018] Furthermore, when installing the waterproof blanket at the pipe inlet, the cloth tube is placed in the groove, and then concrete blocks are thrown into the groove to press the edge of the waterproof blanket.

[0019] Furthermore, for colorless and odorless gases, colored smoke such as yellow, red, and blue and aromatic special odors can be added for auxiliary identification.

[0020] Furthermore, when the pipe burst channel is blocked, the following steps are included:

[0021] S81. Install a cement slurry mixing bucket, a water glass solution dilution bucket, a micro motor, a grouting pump and a double-liquid grouting pipe near the pipe outlet.

[0022] S82. Stir the cement slurry in a cement slurry mixing bucket, dilute the water glass solution in a water glass mixing bucket, install the double-liquid grouting pipe, insert the double-liquid grouting pipe into the pipe flow channel, and then connect the double-liquid grouting pipe to the grouting pump.

[0023] S83. When the pipe inlet is blocked and the water flow gradually decreases until the water stops, start the grouting pump, first clean the pipe channel with water, and then carry out double-liquid grouting to mix the cement slurry and water glass at the outlet of the grouting pipe until the channel is filled.

[0024] Furthermore, the double-liquid grouting pipe is made of elastic plastic pipe. When installing the double-liquid grouting pipe, a steel bar with a length of 10m-20m is inserted into the pipe. By applying pressure to the steel bar, the double-liquid grouting pipe is guided into the pipe flow channel. After the double-liquid grouting enters the pipe flow channel, the steel bar is pulled out, and then the double-liquid grouting pipe is connected to the grouting pump.

[0025] Furthermore, before the piping inlet is completely blocked, the blocking range of the piping inlet is widened, and at the same time, the laying height of the sand above the waterproof blanket is increased until the water flow is stopped, and then the grouting pump is started to grout the piping channel.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention can quickly find and determine the water inlet of piping in the key river section along the inner side of the river bank by regularly floating colored balloons on the river surface. It also eliminates the interference of turbid water flow and vortex generated by floating objects during floods.

[0028] 2. The present invention adopts a wheel hub and a micro motor to drive, loosen or tighten the thin rope, drive the balloon to float downstream or be retrieved upstream, saves manpower and reduces labor intensity.

[0029] 3. The present invention uses drones to shoot on the water surface, and does not require human patrol on the river surface, thus eliminating the risk of patrollers getting into danger in the fast-flowing river water.

[0030] 4. The present invention injects carbon dioxide gas and red or blue pigment water at the pipe inlet, collects carbon dioxide gas near the pipe outlet, verifies it with lime water, and uses red or blue pigment water to enable inspectors to quickly find the pipe outlet, thus avoiding the waste of resources by the human sea investigation tactic.

[0031] 5. The present invention adopts a method of first blocking the pipe inlet and then blocking the pipe channel and the outlet. Compared with blocking only the outlet, the implementation difficulty is small and the blocking success rate is high. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0045] like Figure 1-Figure 11 As shown, a rapid treatment method for river bank piping includes dividing a piping investigation unit in a key river section of a river bank 1 with piping, identifying piping, locating a piping inlet 401, injecting pigment water into the piping inlet 401, locking the position of a piping outlet 402, installing a prefabricated waterproof blanket 5, blowing sand 602 into the waterproof blanket 5, and grouting and plugging a piping channel 4 at the piping outlet 402. The specific implementation steps are as follows:

[0046] S1. Divide the key river section with piping into piping investigation units. Specifically, Figure 1As shown, in a key river section for piping in the river bank 1, a plurality of piping investigation units are divided at certain intervals along the water flow direction 101 within a certain range along the inner edge of the river bank 1, and a hub 202 is installed in each piping investigation unit. The hub 202 is driven by a micro motor 206, and a colored balloon 2 is tied to the hub 202 through a thin rope 205, so that the colored balloon 2 drifts in the water.

[0047] In this embodiment, the width of 10m-20m along the inner side of the river bank 11 is divided into a pipe burst inspection unit every 50m-100m along the water flow direction; Fig. 9 , Fig.11 As shown, when the colored balloons 2 are deployed, a column 201 is inserted at the upstream side of each pipe burst investigation unit, a rotating shaft 203 is installed on the column 201, more than three hubs 202 are installed on the rotating shaft 203, the hub 202 is divided into no less than 3 grids by a partition 204, a 60m-110m long thin rope 205 is wound around each grid of the hub 202, and the rope end of the thin rope 205 is tied with no less than one colored balloon 2.

[0048] The rotating shaft 203 can be driven by a micro motor 206 or manually, thereby driving the hub 202 to rotate. When the hub 202 rotates forward, the thin rope 205 diverges, and a row of colorful balloons 2 with an interval of 0.1m-0.2m will drift downstream along the water flow. When the hub 202 rotates reversely, the thin rope 205 is retracted, and the colorful balloons 2 are dragged back to the hub 202.

[0049] S2. Identify the piping. Figure 2 , Figure 3 As shown, when a piping burst occurs in a piping burst detection unit, a vortex will be generated underwater at the piping burst point. When the colored balloon 2 passes through the vortex, it will rotate along the vortex under the action of suction and may sink, while other balloons will float downstream. The vortex may be caused by the piping burst or other factors. Therefore, when a vortex appears in a piping burst detection unit, it is necessary to identify whether a piping burst has occurred based on the movement state of the vortex.

[0050] When specifically identifying whether a pipe burst has occurred, if the vortex follows the floating object and moves downstream, it is identified as a vortex caused by the obstruction of the floating object; if the vortex produces backwash waves, it is identified as a vortex caused by an obstacle in the river channel; if the position of the vortex is fixed, the vortex is relatively round and the center of the vortex is sunken, it is identified as a vortex caused by a pipe burst.

[0051] S3, locate the pipe inlet 401. Specifically, Figure 1As shown, when it is determined that a pipe burst occurs, the wheel hub 202 is rotated and the colored balloon 2 is towed by a thin rope 205. At the same time, the drone 3 flies back and forth along the pipe burst inspection unit parallel to the river bank 1 to shoot the drift of the colored balloon 2 and synchronously transmit the video back to the monitoring screen 301. When it is found that the colored balloon 2 is rotating or sucked underwater, the coordinates are immediately locked and marked as the pipe burst water inlet 401.

[0052] In this embodiment, the wheel hub is driven to rotate by the micro motor 206, and all pipe burst inspection units start the micro motor 206 once every 0.5 hour to 1.0 hour. At the same time, the drone 3 flies back and forth along the pipe burst inspection units near the river bank.

[0053] S4, such as Figure 4 As shown, one end of a plastic hose 801 is inserted into the paint water bucket 8, and the other end of the plastic hose 801 is inserted into the pipe flow inlet 401, and the paint water is poured into the pipe flow channel; at the same time, one end of the carbon dioxide gas cylinder (9) is connected to the gas outlet with a hose 901, and the other end of the hose 901 is inserted into the pipe flow inlet 401, and the cylinder valve 902 is opened to pour carbon dioxide gas into the pipe flow channel.

[0054] Specifically, the color of the pigment water needs to be clearly distinguished from the color of the flood. In this embodiment, non-toxic red or blue pigment water is prepared and the pigment water is contained in a plastic bucket with a sealed lid.

[0055] S5, such as Figure 4 As shown, the pipe burst outlet 402 is found on the outside of the river bank 1, perpendicular to the pipe burst point and on the ground covered with vegetation 102. A gas collecting bottle 10 with a vacuum cylinder 1001 is used to collect gas. The gas collecting bottle 10 is connected to a glass 1005 filled with lime water by a soft rubber tube 1003. When the lime water becomes turbid, it indicates that carbon dioxide gas has overflowed, and pigment water seepage points are found by turning over the vegetation 102. The pigment water seepage points are marked as pipe burst outlets 402.

[0056] Specifically, carbon dioxide is a non-toxic gas and is insoluble in water. The carbon dioxide collected in a gas collecting bottle is poured into a glass filled with lime water, where a chemical reaction occurs to produce calcium carbonate, and the lime water becomes turbid.

[0057] S6, installing the prefabricated waterproof blanket 5. Specifically, the size of the prefabricated waterproof blanket 5 is selected according to the size of the piping channel 4, a trench 6 is excavated around the piping inlet 401, and the waterproof blanket 5 is installed at the piping inlet 401 and fixed in the trench 6.

[0058] The waterproof blanket 5 can be prefabricated and stored in a temporary emergency material warehouse on the river bank 1 to be used in case of emergency. Fig. 9As shown, in this embodiment, when making the waterproof blanket 5, a waterproof material with a thickness of 2mm-5mm is used for making it, the waterproof blanket 5 is cut into a square with a side length of 2.0m-5.0m and the four corners of the waterproof blanket 5 are cut off, and then a cloth tube 501 is sewn on each side of the waterproof blanket 5, and a steel bar 502 is inserted into the cloth tube 501 and sunk into the groove 6 to fix the waterproof blanket 5, and finally hemp ropes are tied at the four corners of the waterproof blanket 5 to facilitate the adjustment of the waterproof blanket 5 underwater security positioning. Figure 4 , Figure 5 As shown, when installing the waterproof blanket 5, use a speedboat to transport the waterproof blanket 5 to the pipe inlet 401, then place the waterproof blanket 5, put the cloth tube 501 into the groove 6, and after it is placed in place and checked, throw concrete blocks 601 into the groove 6 to press the edge of the waterproof blanket 5.

[0059] S7, blowing sand 602 to the waterproof blanket 5. Specifically, Figure 7 As shown, the sand-blowing ship is parked near the piping point, and sand 602 is blown underwater with the piping point as the center, so that the sand 602 covers the waterproof blanket 5. The laying height of the sand 602 is 2.0m-3.0m, and then stones 603 are thrown on the sand 602 to cover it to prevent the water flow from washing away the sand 602.

[0060] S8, grouting and plugging the pipe flow channel 4 at the pipe flow outlet 402. The specific pipe flow channel plugging includes the following steps:

[0061] S81. Install a cement slurry mixing barrel, a water glass solution dilution barrel, a diesel generator, a grouting pump 7 and a double-liquid grouting pipe 701 near the pipe outlet 402.

[0062] S82, such as Figure 8 As shown, cement slurry is stirred in a cement slurry stirring barrel, water glass solution is diluted in a water glass stirring barrel, a double-liquid grouting pipe 701 is installed, the double-liquid grouting pipe 701 is inserted into the pipe burst channel 4, and then the double-liquid grouting pipe 701 is connected to the grouting pump 7.

[0063] In this embodiment, the double-liquid grouting pipe 701 is made of an elastic plastic pipe, so that the double-liquid grouting pipe 701 has a certain strength and can withstand large bending deformation. When installing the double-liquid grouting pipe 701, a steel bar 502 with a length of 10m-20m is inserted into the pipe. By applying pressure to the steel bar 502, the double-liquid grouting pipe 701 is guided into the pipe flow channel 4. After the double-liquid grouting enters the pipe flow channel 4, the steel bar 502 is pulled out, and then the double-liquid grouting pipe 701 is connected to the grouting pump 7.

[0064] S83. When the pipe inlet 401 is blocked and the water flow gradually decreases until the water stops bubbling, start the grouting pump 7, first clean the pipe channel 4 with water, and then perform double-liquid grouting to mix cement slurry and water glass at the outlet of the grouting pipe 701 until the channel is filled.

[0065] Before the piping water inlet 401 is completely blocked, the blocking range of the piping water inlet 401 can be widened, and at the same time, the laying height of the sand 602 above the waterproof blanket 5 can be increased until the water flow is stopped, and then the grouting pump 7 is started to grout the piping channel 4.

[0066] Through the above-mentioned method for locating and quickly plugging pipe bursts on the river bank 1, the present invention divides pipe burst investigation units within a certain range along the inner side of the river bank 1 in the key pipe burst area of ​​the river bank 1, and uses a method of drifting a colored balloon 2 on the water surface inside the river bank 1 to easily and quickly determine the water inlet position of the pipe burst point, and eliminates the interference of turbid water flow and floating objects blocking the generation of vortices during floods; and the method of injecting carbon dioxide gas and pigment water at the pipe burst water inlet quickly finds the position of the pipe burst outlet 402 on the outer side of the river bank 1. It is convenient for inspectors to quickly find the location of the pipe burst outlet 402, avoiding the waste of resources caused by the human-mass investigation tactic; by first blocking the water inlet and then blocking the pipe burst channel 4 and the water outlet, a waterproof blanket 5 is used to block the pipe burst water inlet 401, and then sand 602 is blown in and covered with stone blocks 603 to strengthen the blocking of the pipe burst water inlet 401, and finally the pipe burst channel 4 is blocked by a double-liquid grouting method at the pipe burst water outlet 402. Compared with blocking only at the water outlet, the implementation difficulty is small and the blocking success rate is high.

[0067] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
