Description

Technical Field

[0001] The invention belongs to the technical field of dike engineering breach plugging, and in particular relates to a geobag breach plugging device that can be quickly deployed on site and an operation method. Background Art

[0002] Due to the extremely uneven distribution of water resources and rainfall, rainfall is mostly concentrated in the summer, which is extremely easy to cause flood disasters. At present, flood disasters caused by heavy rains are gradually showing characteristics such as extreme, sudden and changeable. Under extreme weather and super-standard floods, hidden dangers of infrastructure such as embankment projects are very likely to burst out in a concentrated manner, resulting in breach dangers, and the length of the breach can reach more than 100 meters.

[0003] Breach sealing is an important measure to prevent the further spread of floods and reduce the losses caused by flood disasters. The following points should be noted in breach sealing: First, efficiency and speed are particularly important. Once a breach is formed, it will gradually expand under the action of floods. Therefore, it is necessary to seal it efficiently and quickly, and the sealing materials should be taken locally and nearby as much as possible; secondly, the breach rescue equipment and tools should be reasonably selected, and the use of manpower should be minimized. For example, an excavator can be used to dig soil and bag it, a pump can be used to drain water, and a forklift can be used to transport the filler used to seal the breach, so as to achieve the purpose of quickly sealing the breach.

[0004] At present, the current breach sealing technology and equipment are still relatively primitive, with problems such as difficulty in obtaining materials and low efficiency. When a breach occurs in a dike during the flood season, boulders, trucks and other heavy machinery are often used to throw them into the breach. Boulders need to be transported from a distance, and the difficulty of quarrying is increasing, causing high damage to the environment. Trucks and other heavy machinery slide into the water and are not easy to sink to the bottom under the action of high-speed water flow; existing breach sealing technologies such as steel sheet piles mainly rely on manpower and physical methods. When faced with large-scale breaches, the handling efficiency is not high.

[0005] Therefore, there is an urgent need for a geobag breach sealing device and an operating method that can be quickly deployed on site to solve the problem. Summary of the invention

[0050] The bagging mechanism 3 is liftably arranged above the tipping bucket, and a plurality of large geobags 4 are installed in the bagging mechanism 3 .

[0051] When in use, each large geobag 4 is installed in the corresponding grid of the bagging mechanism 3, and the large geobag 4 is filled by utilizing on-site excavation or selecting solid waste nearby.

[0085] μ>tanθ (2)

[0086] The bagging mechanism 3 is controlled by a hydraulic controller to realize the lifting of the combined frame 16; the combined frame 16 is welded by a plurality of rectangular channel steels, each of which is slightly larger than the size of the large geotextile bag 4, and the overall area of ​​the combined frame 16 is

[0087] S=kl×nb (3)

[0088] Where k is the number of frames along the length of the truck, l is the length of a single frame, n is the number of frames along the width of the truck, and b is the width of a single frame.

[0089] A pressing block is provided in the top groove of the combined frame 16, the purpose of which is to fix the large geobag 4 during bagging.

[0090] The lifting hydraulic rods 14 are supported at the four corners of the bottom of the combined frame 16. When the combined frame 16 is raised, each column acts on the fixed bottom plate 10 without supporting the weight of the large geobag 4.

[0091] The fixed bottom plate 10 and the outer baffle plate 11 are connected to the rotatable platform 2. A slide groove is set at the bottom of the rotatable platform 2, and the first telescopic plate 6 is close to the slide groove; similarly, a slide groove is set at the bottom of the first telescopic plate, and the second telescopic plate 7 is close to the slide groove; the first telescopic plate 6 is connected to the middle baffle plate 12; the second telescopic plate 7 is connected to the inner baffle plate 13.

[0092] The positioning block is arranged at the tail end of the slideway. When the telescopic plate is extended to a certain length, the positioning block can fix the bottom plate and the telescopic plate to prevent the telescopic plate from falling out.

[0093] An operation method of a geobag breach plugging device that can be quickly deployed on site, using the geobag breach plugging device that can be quickly deployed on site, includes the following steps:

[0094] Step 1: Install each large geobag 4 in the corresponding opening of the bagging mechanism 3;

[0095] Step 2: Use the excavated soil on site or the solid waste and other engineering waste soil selected nearby to fill the large geobags 4;

[0096] a. According to the size of the special operation vehicle, select the appropriate size of the combined frame 16 and the large geobag 4, and arrange the bagging mechanism 3 on the rotatable platform 2.

[0097] b. Place a large geobag 4 inside each grid, and place the large geobag 4 that exceeds the frame in the top groove of the combined frame 16.

[0098] c. Fill each large geobag 4. There is no strict restriction on the filler in the bag, and various earth and stone materials or solid waste excavated on site or nearby are preferred.

[0099] Step 3: After the large geobag 4 is filled and sealed, the bagging mechanism 3 is started to make the lower surface of the bagging mechanism 3 flush with the upper surface of the sealed large geobag 4;

[0100] After the geobags are filled, the bagging mechanism 3 is started to align the lower surface of the platform with the upper surface of the geobags. At this time, the geobags are basically formed.

[0101] Step 4: Connect several large geobags 4 into one, and then repeat the above steps to fill and connect the second layer of large geobags 4;

[0102] a. Reinforced belts can be used to connect several geobags to form large series-connected geobags.

[0103] b. Repeat the above steps to prepare the second layer of geobags.

[0104] Step 5: After all the large geobags 4 are filled, the slide device 5 is opened and the bucket is tilted. After the bucket reaches a specified inclination angle, the large geobags 4 slide down along the slide device 5 to the breach;

[0105] At this point, the large geobags have been connected in series. However, it is more important to accurately slide the large geobags in series for breach plugging to the breach position. Therefore, it is necessary to calculate the distance between the equipment and the breach before the breach plugging operation and optimize the distance.

[0106] First, it is necessary to clarify the mass mg, volume V, breach depth H, breach flow velocity v, and height h of the slide plate from the water surface of the large series geobag.

[0107] The trajectory of the series-connected large geobag after sliding into the breach is:

[0108] D=(D x ,D y ) (4)

[0109] According to the law of conservation of energy and Newton's second law, the horizontal and vertical motion equations of large series geobags in breach flow can be established:

[0110]

[0111] The unknown coefficients C1 and C2 can be solved by optimization theory:

[0112]

[0113] Based on the above, the optimal distance required for breach sealing using large-scale tandem geobags can be obtained.

[0114] When encountering a breach, move the mobile platform to a safe position, the distance from the breach being no greater than the length of the fully extended telescopic plate. At this time, point the tail of the platform toward the breach, extend the slide plate, and then start the hydraulic lifting system to slowly and evenly raise the platform. When the bottom plate reaches the predetermined inclination angle, the tandem large geobags slide down to the breach.

[0115] Step 6: Repeat the above steps until the dangerous situation is resolved.

[0116] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0117] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
