Description

Technical Field

[0001] The invention belongs to the technical field of dike breaches, relates to a dike breach closing method, and particularly relates to a dike breach quick closing method based on rocket anchors and steel pipe piles. Background Art

[0002] As an important part of water conservancy projects, dikes can prevent flooding, protect residents and industrial and agricultural production, and have significant social and economic benefits. However, once a dike breaks, it will not only cause great harm to people and property in the surrounding areas, but may also cause ecological damage and social chaos. Therefore, timely sealing of dike breaches is of great significance. Closing is the most critical project in breach sealing. During the closure, the water flow in the breach is turbulent and the construction conditions are complex. The slightest carelessness may lead to the failure of breach sealing. In history, the phenomenon of breach sealing failure due to closure problems often occurs. Therefore, how to quickly close the dike breach is an urgent problem to be solved.

[0003] At present, there are two common technologies for closing dike breaches: closing with a sluice and throwing pillows. Before the 20th century, closing with a sluice was commonly used, while after the 20th century, throwing pillows were commonly used. Both closing with a sluice and throwing pillows have the advantages of simple construction and rapid plugging. However, in the case of deep water and rapid flow, the closing sluice technology may cause the sluice to get stuck or twisted, so that the sluice cannot be pressed to the bottom, and the flow velocity under the sluice is too high, which scours the riverbed and reduces the stability of the closing sluice; the throwing pillow technology has a large gap between pillows and serious water leakage, resulting in poor anti-impact force.

[0004] In view of this, for dike breaches in extreme environments, the stability of a single closure technology is poor and cannot meet the needs of rapid sealing of breaches. In response to this problem, some researchers, based on the closure technology requirements of "convenient operation, rapid construction, and easy access to local materials", combined with the development of traditional closure materials, pontoon bridge technology, wire mesh and stone loading machinery, and drawing on the experience and technology of mechanical stone throwing in the lower reaches of the Yellow River, filling sand and filling geotextile long tube bags on ships and throwing them into the water for closure, proposed a combined soft row and giant wire mesh gabion technology to achieve closure; a method of emergency blocking of dike breaches, proposed the use of excavators, loaders and other machinery combined with tree branch assemblies and wire mesh gabions to close breaches. In addition, steel-wood earth-rock dams, shipwrecks and helicopter throwing of large stone bags have also been used in closure and blocking at home and abroad.

[0005] In summary, how to use mechanized rescue equipment with high-intensity ability to throw large-volume engineering materials, combined with traditional closure technology, to achieve rapid closure of breaches in extreme environments and significantly improve my country's embankment breach rescue technology is a need for flood control and disaster reduction. Summary of the invention

[0006] The purpose of the present invention is to provide a method for quickly closing a dike breach based on rocket anchor and pile planting technology.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A method for rapid closure of dike breaches based on blocking coordination, firstly, quickly throw a large nylon net to build a wrap; secondly, construct an entry body based on a geotextile bag; finally, use rocket anchors, pile planting technology combined with water-filled rubber bags, steel mesh gabions, stones, and soil to complete the closure of the dike breach. It includes the following steps:

[0009] The first step is to throw a large nylon net to both sides of the breach in the dike, build a wrap to stabilize the broken dike and prevent it from further expanding.

[0010] The second step is to throw geotextile bags on both sides of the breach to form a flow-reducing and buffering body, creating conditions for subsequent closure and providing a construction site.

[0011] The third step is to complete the closure of the dike breach, as follows:

[0012] (3.1) Launching rocket anchor and dropping water-filled rubber bag:

[0013] (3.1.1) Place an inflatable cushion on the bank of the breach. After the inflatable cushion is filled with gas through the inflation hole, put an unfilled water-filled rubber bag into the inflatable cushion. Then use a water pump to fill the water through the water-filling hole on the water-filled rubber bag until the water-filled rubber bag is full of water. Then, connect the hook on the water-filled rubber bag to the fixed pile on the bank with a rope.

[0014] (3.1.2) The rocket anchor is launched at the pre-set position and angle. After the rocket anchor is anchored to the bottom of the water, it is tied to the hook arranged on the water-filled rubber bag through the anchor cable, so that the water-filled rubber bag is connected to the rocket anchor. Then, the cable on the ship is tied to the inflatable cushion, and the water-filled rubber bag is dragged and dropped to the predetermined position of the breach. The explosives placed on the inflatable cushion are detonated, and the cable is released. After the water-filled rubber bag sinks to the bottom of the water, the rope is tied. At the same time, the anchor cable of the rocket anchor is tightened to apply anchoring force to the water-filled rubber bag. Multiple water-filled rubber bags are thrown continuously to form a water barrier.

[0015] (3.2) Implanting steel pipe piles: implant a row of steel pipe piles with a pile spacing of 1.5m on the backwater side of the water-filled rubber bag to further stabilize the constructed water barrier.

[0016] (3.3) Throwing steel mesh gabions: throwing steel mesh gabions on both sides of the breach, and filling the gaps in the sealing body with stones and soil to form a embankment breach sealing body based on rocket anchors and steel pipe piles.

[0017] Furthermore, in the first step, the width of the wrapping head is 15m to 20m, the bottom of the wrapping head is in contact with the bottom of the water, and the top is higher than the water surface, with a height of 1m to 2m; and the large nylon net is filled with sandbags.

[0018] Furthermore, in the second step, the width of the occupying body is determined according to the conditions suitable for closure, the bottom of the occupying body is in contact with the bottom of the water, and the top is higher than the water surface, with the excess height being 1m to 2m.

[0019] Furthermore, in the third step, the diameter and length of the anchor cable are determined according to the anchoring position set by the rocket anchor and the hydraulic conditions of the breach, and the material is steel wire.

[0020] Furthermore, in the third step, the water-filled rubber bag has a cloth thickness of 3 mm and is placed perpendicular to the water flow direction. After being filled with water, the length is determined according to the width of the joint, which is 5m to 6m in width and 3m to 4m in height; the rope material is nylon rope with a diameter of 6mm to 10mm; the shore fixed pile has a diameter of 10cm to 20cm and a length of 1m to 2m.

[0021] Furthermore, in the step (3.2), the diameter of the steel pipe pile is 30 cm to 45 cm, and the length is 15 m to 20 m.

[0022] Furthermore, in the step (3.3), the width of the joint is determined according to the flow, soil quality, and riverbed section, the bottom of the joint body is in contact with the water bottom, and the top is above the water surface, with the excess height being 1m to 2m.

[0023] The present invention solves the problem that the existing closure technology cannot quickly close the joint under the condition of deep water and rapid current, and has at least the following advantages:

[0024] (1) The water-filled rubber bag has the advantages of good integrity, simple structure, convenient transportation, and convenient construction. The anchoring force provided by the rocket anchor can make the water-filled rubber bag "take root" under high-speed water flow, quickly build a water-blocking body for flow reduction and buffering, and rely on the formed water-blocking body to plant piles, which can effectively alleviate the difficulty of planting piles in extreme environments. At the same time, the pile body can also play a role in supporting the water-blocking body, further increasing the stability of the water-blocking body, and providing good construction conditions for throwing steel mesh gabions, stones and soil.

[0025] (2) Rocket anchor and pile technology are highly modularized, easy to construct, and highly efficient. Other materials used are easily available locally, and can be used to reach the rescue site in time and quickly construct when floods occur. At the same time, the plugging materials used (such as water-filled rubber bags, steel mesh gabions, stones, and soil) are easy to obtain locally and can be thrown quickly.

[0026] To sum up, the present invention fully combines the advantages of mechanized equipment and traditional closure technology, and adopts rocket anchors, piles, water-filled rubber bags, steel mesh gabions, stones, and soil materials to achieve rapid closure of embankment breaches, timely and effectively reduce disasters, and has the characteristics of scientific principles, high sealing efficiency, safety and reliability.
