Description

Technical Field

[0001] The invention relates to the technical field of pipe burst blocking, in particular to a segmented convergence type embankment pipe burst emergency blocking device. Background Art

[0002] Piping refers to the phenomenon that under the action of seepage, the fine particles of soil are formed along the skeleton particles, and the flow rate of water in the soil pores increases, causing the fine particles of soil to be washed away. When piping occurs, the water surface appears to be rippled. As the upstream water level rises and the duration is prolonged, the dangerous situation continues to worsen. A large amount of water gushes out and turns over sand, destroying the soil skeleton of the foundation of embankments and sluices, expanding the pores, and hollowing out the base soil, causing building collapse and resulting in accidents such as breach of dikes, collapse of dams, and failure of sluices.

[0003] At present, the method for emergency rescue of pipe bursts is to tie a geotextile bag to a steel pipe and extend it into the pipe burst channel, and then inject a polymer material into the bag through the steel pipe to make it swell when it comes into contact with water and block the pipe burst channel. However, the hardness of the mud and sand around the pipe burst channel becomes lower due to the seepage effect. When it is blocked, new pipe bursts are prone to occur, and the distribution of the internal conditions of the pipe burst is not uniform.

[0034] During implementation, the device is placed at the pipe burst, and the geotextile bag is fixed on the support plate 22 by the clamping assembly 5. Then, the fixing seat 1 is fixed to the pipe burst mouth by the fixing mechanism 13, and sealed by the sealing gasket 14. Then, the tamping assembly 3 is lowered into the pipe burst channel by rotating the swivel ring 12. During this process, the grouting pipe 39 can be inserted into the bottom of the geotextile bag. Then, the driving ring 32 is driven by the motor to rotate clockwise, and the gear rod 35 is driven to rotate, so that the tamping plate 33 is propped up. Then, the driving ring 32 is driven by the motor to rotate counterclockwise, and the ratchet assembly 36 drives the tamping seat 31 to rotate, so that the tamping plate 33 rotates with the tamping seat 31. It starts to rotate, and under the action of spring 134, it strikes and compacts the inner wall of the pipe burst, further increases the hardness of the mud and sand around the pipe burst channel, and prevents new pipe bursts after blocking. After compaction, the driving ring 32 is driven to rotate clockwise, and the compaction plate 33 is retracted. Then, polymer material is filled into the grouting pipe 39, which pushes the flow block 392 to slide under the action of pressure, and injects the polymer material into the geotextile bag. Then, the swivel 12 is rotated to move the compaction component 3 upward in sections, and after moving up a certain distance, the geotextile bag is tightened by the tightening component 4, so that the geotextile bag expands in sections, further improving its blocking effect.

[0035] In this embodiment, Figure 2 and Figure 3 The tamping assembly 3 includes a tamping seat 31, a driving ring 32 and a tamping plate 33, wherein the driving ring 32 is rotatably arranged on the tamping seat 31, a plurality of tamping plates 33 are rotatably arranged on the tamping seat 31, and a spring 34 is arranged between the tamping plate 33 and the tamping seat 31.

[0038] The driving ring 32 is driven by a motor 1, and a ratchet assembly 36 is disposed between the driving ring 32 and the tamping seat 31 .

[0039] In particular, a plurality of tamping plates 33 are provided and controlled by a spring 34 so that the tamping plates 33 can be tightly attached to the inner wall of the piping channel, ensuring that the tamping plates 33 can tamp various parts of the inner wall of the piping channel, thereby further improving the tamping effect. Furthermore, by providing a ratchet assembly 36, the three working states of contraction, propping up and tamping the inner wall of the piping channel of the tamping plates 33 can be realized only by the motor 1, thereby further improving its convenience.

[0040] In this embodiment, Figure 2 and Figure 4 The drive ring 32 and the gear lever 35 are also provided with threads 37 on the outside;

[0041] A swivel ring 12 is rotatably provided on the water-blocking plate 11, and a thread groove identical to the thread 37 is provided inside the swivel ring 12.

[0044] Furthermore, a slot is provided on the support plate 22, and the cross rod can slide along the slot in a limited manner.

[0045] During implementation, the support plate 22 and the geotextile bag do not move, and the grouting pipe 39 moves downward to extend into the bottom of the geotextile bag, and drives the geotextile bag to extend into the piping channel, ensuring that the geotextile bag can extend into the piping channel.

[0046] In this embodiment, Figure 2 The tightening assembly 4 includes a swivel 2 41 and a swivel 3 42, wherein the swivel 2 41 is fixedly arranged at the bottom of the support ring 38, and the swivel 3 42 is rotatably arranged on the swivel 2 41, a pay-off wheel 1 43 is rotatably arranged at the bottom of the swivel 2 41, and a pay-off wheel 2 44 is rotatably arranged at the bottom of the swivel 3 42, and multiple circles of tightening belt are wound around the pay-off wheel 1 43, and the other end of the tightening belt is wound around the pay-off wheel 2 44.

[0047] In this embodiment, Figure 2 , the height of the second pay-off wheel 44 is higher than the height of the first pay-off wheel 43;

[0048] Furthermore, the pay-off wheel 1 43 and the pay-off wheel 2 44 both rotate flexibly, and can tighten the tightening belt.

[0049] During implementation, the swivel 12 rotates, driving the compaction assembly 3 and the grouting pipe 39 to move upward in sections. After moving upward for a certain distance, the swivel three 42 is rotated, which drives the pay-off wheel two 44 to rotate, and under the action of the pay-off wheel one 43, the tightening belt is tightened on the geotextile bag, and the pay-off wheel one 43 and the pay-off wheel two 44 both rotate flexibly, which always tightens the tightening belt to ensure that the geotextile bag is tightened.

[0050] In this embodiment, Figure 6 and Figure 7 The clamping assembly 5 includes a clamping seat 51, a clamping block 52 and a push ring 53, wherein the clamping seat 51 is fixedly arranged at the bottom of the support plate 22, a plurality of clamping blocks 52 are rotatably arranged inside the clamping seat 51, the push ring 53 is rotatably arranged inside the clamping seat 51, a plurality of protrusions 54 are arranged inside the push ring 53, and the push ring 53 can drive the protrusions 54 to rotate and drive the clamping block 52 to deflect, and the clamping block 52 is also provided with a groove of the same size as the protrusion 54;

[0051] A push rod 55 is also fixedly disposed on the push ring 53 .

[0052] During implementation, the geotextile bag is placed on the outside of the support plate 22, and then the push ring 53 is rotated so that the protrusion 54 pushes the block 52 to deflect, making it close to the support plate 22 to fix the geotextile bag. In addition, the protrusion 54 can be stuck in the groove to further ensure the stability of the push ring 53 and prevent the geotextile bag from falling when it expands.

[0053] In this embodiment, Figure 3 and Figure 4 The front end of the grouting pipe 39 is also provided with a flow blocking member, which includes a flow blocking seat 391 and a flow blocking block 392, wherein the flow blocking seat 391 is fixedly arranged at the output end of the grouting pipe 39, and the flow blocking block 392 is slidably arranged in the flow blocking seat 391;

[0054] The baffle block 392 is in an I-shape, and a second spring 393 is disposed between the baffle block 392 and the baffle seat 391 .

[0055] During implementation, polymer material is injected into the grouting pipe 39, which pushes the baffle block 392 to slide under the action of pressure and compresses the spring 2 393. Then the polymer material flows out from the gap between the baffle block 392 and the baffle seat 391 and fills the geotextile bag. After grouting is completed, the baffle block 392 can block the baffle seat 391 under the action of the spring to prevent water from flowing back into the grouting pipe 39, causing the polymer material in the grouting pipe 39 to swell when it comes into contact with water, causing damage to the grouting pipe 39.

[0056] In this embodiment, Figure 1 The fixing seat 1 is also provided with a fixing mechanism 13, which includes a fixing plate 131, a drilling motor 132 and a drill rod 133, wherein a plurality of the fixing plates 131 are fixedly provided on the fixing seat 1, a drilling motor 132 is fixedly provided on the fixing plate 131, and a drill rod 133 is provided at the output end of the drilling motor 132;

[0057] A sealing gasket 14 is also fixedly disposed at the bottom of the fixing seat 1 .

[0058] During implementation, the drilling motor 132 drives the drill rod 133 to rotate, and the drill rod 133 gradually penetrates into the mud outside the pipe burst outlet, and drives the fixed seat 1 to move downward, so that the sealing gasket 14 is close to the outer wall of the pipe burst outlet, and the pipe burst outlet is simply sealed. Under the action of the water-blocking plate 11, water is prevented from flowing into the compaction component 3, ensuring that the internal polymer material of the geotextile bag expands when it encounters water after it is extended into the pipe burst channel.

[0059] To sum up, when the present device is implemented, the water-blocking plate 11, the fixing mechanism 13 and the sealing pad 14 are used to simply seal the pipe burst mouth, and then the geotextile bag is fixed on the support plate 22 by the clamping assembly 5, and then the compacting assembly 3 is used to compact the inner wall of the pipe burst channel, so that the hardness of the mud and sand around the pipe burst channel is increased to prevent new pipe bursts from occurring after blocking, and then, by utilizing the action of the swivel 12 and the tightening assembly 4, the working state of grouting while moving upward is performed, and the geotextile bag is segmentedly contracted, so that the polymer material is segmentedly expanded, the pipe burst channel is blocked, and its blocking effect is further improved.
