Description

Technical Field

[0001] The invention relates to the technical field of water conservancy project embankment breach plugging, and in particular to a breach rapid plugging device and method based on a rocket anchor and a polymer composite material. Background Art

[0002] As a key component of the flood control system, levees play an important role in protecting human activities and the natural environment from floods. In recent years, due to extreme rainfall and rising water levels caused by climate change, levee breaches have occurred frequently, posing serious challenges to society and the economy. Breaching not only causes a large number of casualties and property losses, but may also trigger a chain reaction and affect the ecological environment of downstream waters. Levee breaches are characterized by rapid occurrence, great impact, and serious consequences. Although there are various levee monitoring and maintenance measures in various places, the existing emergency response technologies are still insufficient in the face of sudden breaches. Therefore, it is urgent to propose a new type of levee breach plugging method that can effectively prevent further development of floods in a short time. The plugging technology should have the advantages of rapid deployment, easy operation, strong material adaptability, and can be flexibly adjusted for different breach situations.

[0003] The existing dike breach blocking solutions have the following problems:

[0004] (1) Current plugging materials are often limited to traditional materials, such as sandbags, stones, concrete blocks, etc. When these methods are implemented in emergency situations, there are problems such as long preparation cycles, complex operations, and poor results. Traditional materials often fail to meet the requirements for adaptability and stability when facing different types of breaches, resulting in plugging failure and further expansion of the breach range. In addition, the hydraulic conditions at the breach during the plugging process need to be monitored in real time as a basis for the next analysis and decision-making of on-site experts.

[0005] (2) The existing wrapping technology for the broken dike head generally uses materials such as boxes and long pillows. This method has a certain applicability under small flow conditions. Under large flow and high flow conditions, these materials are easily washed away by the water flow due to their light weight, resulting in a waste of resources. At the same time, the existing wrapping technology often uses a single wrapping method. After the wrapping is completed, if the water flow speed upstream of the breach increases, the stability of the single wrapping structure is not high, resulting in further instability and damage to the broken dike head.

[0006] (3) During the air-locking stage, the traditional air-locking method is generally to lay a sand-filled long tube bag soft material row on the upstream slope of the entry body, and then throw in the geotextile bag. This method has good applicability when the embankment has sufficient sand and soil materials, but it requires more manpower and material resources and has low construction efficiency. Summary of the invention

[0007] The purpose of the present invention is to provide a device and method for rapid breach plugging based on rocket anchors and polymer composite materials, so as to solve the problems raised in the above-mentioned background technology, realize rapid protection of the broken dike head, and ensure stable plugging and airtightness of the breach.

[0008] To achieve the above-mentioned purpose, the present invention provides a breach rapid plugging device based on a rocket anchor and a polymer composite material, comprising a broken dike head on both sides of the breach, a wrapping structure is arranged on the outer periphery of the broken dike heads on both sides, the wrapping structure comprises a first line of protection and a second line of protection, the second line of protection is connected to a fixed structure, and the fixed structure is arranged on the broken dike head;

[0009] An entry and closure structure is arranged between the head wrapping structures on both sides, and two ends of the entry and closure structure are connected to the head wrapping structures on both sides.

[0010] Preferably, the first line of protection includes a plurality of large geotextile bags arranged around the outside of the breakwater head.

[0011] Preferably, the second line of protection comprises a polymer anti-seepage wall, which is made by stacking a number of polymer geosynthetics monomers, the polymer geosynthetics monomers comprising a double-layer geotextile, the interior of the double-layer geotextile is provided with fillers, and the exterior of the double-layer geotextile is fixed with a hexagonal steel mesh.

[0012] Preferably, the filler is one of a polymer water-absorbing resin and an expandable polyurethane foam.

[0013] Preferably, a plurality of rubber bags to be filled with water are arranged side by side on the outer side of the polymer anti-seepage wall.

[0014] Preferably, the fixed structure includes several rows of plum blossom piles driven at the top of the broken dike, one end of a steel wire rope is connected to the plum blossom piles, and the other end of the steel wire rope is connected to the bottom of the rocket anchor; one end of a hook is sleeved on the steel wire rope, and the other end of the hook is connected to the polymer geosynthetics monomer.

[0015] Preferably, a conical tip is provided at the bottom of the rocket anchor, and a spiral portion is provided at the top of the rocket anchor.

[0016] Preferably, the joint structure includes triangular column mesh cages, steel mesh gabions and hollow cylindrical pipe piles, the hollow cylindrical pipe piles are arranged in multiple rows and staggered, and the hollow cylindrical pipe piles are provided with multiple rows of through holes;

[0017] A number of triangular column mesh cages and a number of steel mesh gabions are stacked on the inner side of the hollow cylindrical pipe piles.

[0018] Preferably, the hollow cylindrical pipe pile is filled with a non-water-reactive polymer material.

[0019] The plugging method of the breach rapid plugging device based on rocket anchor and polymer composite material comprises the following steps:

[0020] Step S1, preparation before construction, stacking a plurality of large geotextile bags, polymer geosynthetics monomers and steel mesh gabions neatly on the top of the broken dike;

[0021] Step S2: monitor the hydraulic characteristics of the breach through drones, analyze the flow velocity, the water level difference between upstream and downstream of the breach, and the flow hydraulic conditions, select the best time to seal, and use dump trucks to throw large geotextile bags to make the outer side slopes of the broken dikes on both sides flat for further construction;

[0022] Step S3, using the data transmitted by the drone, multiple rows of plum blossom piles are driven on the top of the broken dikes on both sides of the breach, rocket anchors are launched from the outside of the large geotextile bag to the riverbed at the bottom of the breach according to the set position, and polymer geosynthetics monomers are slid along the wire rope. After the sliding is completed, rubber bags to be filled with water are arranged on the outside of the formed polymer anti-seepage wall, and water is filled into the rubber bags to be filled with water at the broken dike head to further compact the polymer anti-seepage wall;

Then, a bulldozer is used to gradually push and fill the soil from both sides.

[0024] Step S5: After the closure is completed, a grouting machine is used to inject non-water-reactive polymer material into the hollow cylindrical pipe pile, so that the polymer material overflows from the through hole of the hollow cylindrical pipe pile to fill the gap and complete the air sealing.

[0025] Therefore, the present invention adopts the above-mentioned breach rapid plugging device and method based on rocket anchor and polymer composite material, which has the following beneficial effects:

[0026] (1) The present invention uses large geotextiles to stabilize the dike head. Based on the characteristics of non-water-reactive polymer materials that swell when exposed to water, a rapid plugging method based on rocket anchors and polymer geosynthetics is proposed. Finally, a rubber bag to be filled with water is used for pressure, which further improves the stability of the wrapping head and has the advantages of fast plugging speed and high efficiency. On the other hand, the plugging process often cannot effectively observe the hydraulic conditions at the breach in a timely manner. The present invention uses a method of drone observation and real-time data transmission to ensure the timely transmission of information during the plugging process, which is convenient for the formulation of further plugging plans.

[0027] (2) The groutable hollow cylindrical pipe piles proposed in the present invention can serve as a supporting structure, which is beneficial to the stability of the subsequently cast steel mesh gabions and triangular column mesh cages, and can also be quickly sealed after the joint is completed, thereby improving the overall plugging efficiency.
