Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy engineering equipment, and in particular relates to a levee breach rapid sealing system. Background Art

[0002] A dike breach refers to a serious disaster in which a dike partially or completely collapses due to natural or human factors, causing flooding. In the existing technology, most methods of blocking are to push forward from both ends of the breach to the middle (vertical blocking) or to fill up layer by layer from the bottom (flat blocking). For example, in the blocking of the Tuanzhouwan breach in Huarong County, Hunan Province, a scheme of "two-way vertical blocking, overwater throwing, and sudden closure" was adopted, combined with GPS and unmanned boat monitoring data to guide the throwing. In actual operation, sandbags, gabions, steel cages and other materials are used for interception. However, due to the high flow rate and high water pressure at the breach, the sandbags, gabions and steel cages placed at both ends of the breach are often washed away by the water flow, causing them to shift in position or be directly washed away. This affects the blocking efficiency and wastes relevant blocking materials. At the same time, the movement of larger sandbags, gabions and steel cages will also take away the sand and gravel in the breach, which tends to expand the breach. Summary of the Invention

[0028] See also Figure 1-10 The present invention provides a technical solution for a rapid embankment breach sealing system:

[0029] After the levee breach occurs, water flows from the water side of the levee 1 along the breach 2 to the backwater side of the levee 1. Under the impact of the water flow, the breach 2 becomes trumpet-shaped. Under the action of the water flow, the mud, stones, etc. at the breach 2 gradually disappear, causing the breach 2 to gradually expand. In order to quickly seal the breach 2, the present application proposes a rapid sealing system for levee breaches, including a jacking support 4 fixed on the levee 1 by a positioning anchor rod 3. The positioning anchor rod 3 is driven into the foundation of the levee 1 by a hydraulic impact hammer. Multiple anchor rods are arranged side by side, and a connecting fastener 5 is provided on the positioning anchor rod 3. The jacking support 4 is connected to the positioning anchor rod 3 through the connecting fastener 5.

[0030] A fixed arm is arranged between the pushing support 4 and the breach 2, and the fixed arm is divided into a first fixed arm 6 and a second fixed arm 7. The first fixed arm 6 is arranged on the water side of the embankment 1, and the second fixed arm 7 is arranged on the backwater side of the embankment 1. Since the breach 2 is trumpet-shaped, when the first fixed arm 6 and the second fixed arm 7 are parallel, the length of the first fixed arm 6 above the breach 2 is longer than the length of the second fixed arm 7 above the breach 2.

[0031] A plurality of positioning anchor rods 3 are arranged along the length direction of the fixed arm, a sliding fastener 8 is arranged on the positioning anchor rod 3, the fixed arm is slidably arranged along the sliding fastener 8, a first hydraulic jack 9 is arranged between the jacking support 4 and the fixed arm, one end of the first hydraulic jack 9 is connected to the jacking support 4, and the other end is connected to the fixed arm.

[0032] To adjust the position of the first and second fixing arms 6, 7, additional anchor rods 3 are driven along the length of the arms, and sliding fasteners 8 are added to the corresponding anchor rods 3. The arms are then moved by actuating the first hydraulic jack 9. Similarly, the jacking support 4 is moved toward the breach 2 in the same manner.

The transverse support arm 13 is driven to slide along the second fixed arm 7 by the second hydraulic jack 17. When the transverse support arm 13 slides, the longitudinal support arm 10 slides and rotates relative to the transverse support arm 13.

[0034] Positioning guides 19 are provided on the transverse support arms 13 and the longitudinal support arms 10. These guides are used to position blocking anchors 38, which are then anchored downward along the guides 19 into the foundation of the breach 2 of the embankment 1.

A limited rotation slot 21 is provided in the positioning hole 20, and the blocking anchor rod 38 is provided with a limited rotation rib 22 along its length direction. The limited rotation rib 22 is adapted to the limited rotation slot 21. When installing the blocking anchor rod 38, the limited rotation rib 22 is made to correspond to the limited rotation slot 21, and then the blocking anchor rod 38 is inserted into the positioning hole 20.

There are two limiting plates 26. The two limiting plates 26 are symmetrically arranged about the anti-slip block 24. A torsion spring is provided at the rotation axis of the limiting plate 26. Under the action of the torsion spring, the positioning guide seat 19 is located between the positioning arc plate 25 and the limiting plate 26. A limiting assembly is provided between the two limiting plates 26. A rotating seat 27 is provided on the anti-slip block 24. The limiting plate is rotatably arranged on the rotating seat 27. The rotating seat The locking cam 32 is provided on the locking cam 32 so that the locking cam 32 is locked and the locking cam 32 is locked. The trigger block 34 is disposed at the middle or top of the blocking anchor rod 38 . In this embodiment, the trigger block 34 is disposed at the top of the blocking anchor rod 38 .

[0037] A connecting shaft 35 is provided on the outside of the anti-slip block 24, and two adjacent clamping components are connected by a connecting rod 36. One end of the connecting rod 36 is rotatably connected to the connecting shaft 35, and the other end of the connecting rod 36 is provided with a waist-shaped adjustment groove 37, which is adapted to the connecting shaft 35 of the adjacent clamping components.

[0038] This application proposes a method and working principle for sealing dike breaches:

[0039] First, the relevant data of the breach 2 is measured by the existing aerial remote sensing technology. Then, the jacking support 4 and the fixed arm are built on the embankment 1, such as Figure 2 As shown, after the first fixed arm 6 and the second fixed arm 7 are erected and fixed, the longitudinal support arm 10 is made perpendicular to the two fixed arms by driving the second hydraulic jack 17. At this time, the transverse support arm 13, the longitudinal support arm 10, the first fixed arm 6 and the embankment 1 at the breach 2 form a trapezoidal area.

[0040] Then, a clamping assembly is installed on each positioning guide seat 19 , and adjacent clamping assemblies are connected by a connecting rod 36 .

[0041] Then, a blocking anchor rod 38 is installed on each positioning guide seat 19 accordingly, and each blocking anchor rod 38 is installed one by one by a crane. The bottom end of the blocking anchor rod 38 sinks into the breach 2 under the action of gravity, and does not deviate under the action of the positioning guide seat 19. After all the blocking anchor rods 38 are in place, a hydraulic impact hammer is used to progressively hammer the blocking anchor rods 38 one by one to drive them into the foundation at the breach 2. In this embodiment, the blocking anchor rods 38 on the positioning guide seat 19 on the transverse support arm 13 are hammered first, and the hammering order is first the blocking anchor rods 38 away from the breach 2 and then the blocking anchor rods 38 close to the breach 2, and then the blocking anchor rods 38 on the longitudinal support arm 10 are hammered, first the blocking anchor rods 38 close to the backwater side of the levee 1 and then the blocking anchor rods 38 close to the water side of the levee 1.

[0042] After all the blocking anchor rods 38 are driven into the foundation and the upper ends of the blocking anchor rods 38 are kept in the positioning holes 20 of the positioning guide seat 19, geotextile sandbags or large stones or steel mesh gabions are placed into the area formed by the blocking anchor rods 38 and the embankment 1 until the area is completely filled and compacted, and then a hydraulic impact hammer with a diameter smaller than the positioning hole 20 is used to further hammer the blocking anchor rods 38 downward so that the upper ends of the blocking anchor rods 38 do not contact the positioning guide seat 19.

[0043] During the above process, the clamping assembly moves completely from the positioning guide seat 19 to the blocking anchor rod 38. Specifically, as the blocking anchor rod 38 is hammered downward, after the trigger block 34 on the blocking anchor rod 38 contacts the sliding block 28, as the blocking anchor rod 38 moves, the trigger block 34 contacts the wedge surface 33 of the sliding block 28, causing the sliding block 28 to slide. This sliding movement of the sliding block 28 drives the blocking wing plate 29 out of contact with the limit plate 26. Subsequently, the limit plate 26 rotates under the action of the anti-slip notch 23 and the trigger block 34, and moves downward along the anti-slip notch 23, following the anti-slip block 24 and moving simultaneously with the blocking anchor rod 38 until it is completely free of the positioning guide seat 19. However, the clamping assembly is completely mounted on the blocking anchor rod 38, so that adjacent blocking anchor rods 38 are connected via the clamping assembly and the connecting rod 36.

[0044] After completing the above-mentioned blocking, the transverse support arm 13 is moved so that the transverse support arm 13 and the longitudinal support arm 10 are moved to the next area. Specifically, the rotation of the longitudinal support arm 10 is set to rotate at one end of the first fixed arm 6, and the other end moves under the action of the transverse support arm 13 and rotates relative to the transverse support arm 13, so that the transverse support arm 13 and the longitudinal support arm 10 form an acute angle. Then, the clamping assembly and the blocking anchor rod 38 are installed on the corresponding positioning guide seat 19. Finally, the blocking anchor rod 38 is hammered in the above-mentioned manner, and then the filler is added to block and fill. After the filling is completed, the breach 2 is reduced from its original larger trumpet shape. Finally, the above process is repeated to gradually block the breach 2.

[0045] In the above process, closing-type sealing can be achieved by operating simultaneously on both ends of the embankment breach.
