Description

Technical Field

[0001] This application relates to the fields of water conservancy engineering and flood control and emergency rescue technology, and in particular to a rapid sealing truss device for filling dike breaches. Background Technology

[0002] In water conservancy projects, dikes are used to block water flow and regulate water levels. During floods, the impact of the water flow can cause dikes to breach. The water flowing through the breach will move from upstream to downstream. For ease of description and sealing operations, we refer to the dike upstream of the breach as the upstream dike and the dike downstream as the downstream dike. Sealing a dike breach can quickly stop the water flow, reduce the extent of flooding, and protect people's lives and property.

[0003] Based on this, modular assembly structures have emerged. Existing modular assembly structures include truss components and pile components. The pile components include upstream and downstream piles, which are respectively implanted into the upstream and downstream dikes on the water flow side. The two ends of the truss are fixed to the upstream and downstream dikes via connectors. Subsequently, weights are added to the truss to make it sink into the water under its own weight. However, due to the relatively long length of the truss, adding weights to the middle of the truss is inconvenient and needs improvement. Utility Model Content

[0004] In order to enable the addition of heavy objects to various positions of the truss, this application provides a filling-type dam breach rapid sealing truss device.

[0005] The technical solution of the rapid sealing truss device for filling dam breaches provided in this application is as follows: A rapid sealing truss device for filling dam breaches includes an upstream pile body, a downstream pile body, and a truss assembly. The upstream and downstream pile bodies are respectively located on the water-facing side of the upstream and downstream dams. The truss assembly includes multiple trusses and an installation component for connecting the trusses. The trusses at both ends are connected to the upstream and downstream pile bodies, respectively. A filling box is provided on one side of the truss, and the filling box has an opening on its upper side. A slide rail is provided on one side of the filling box, and the slide rail is equipped with a slider. The slider is equipped with a detachable filling tube for adding filling material to the filling box. The truss is equipped with a detachable float.

[0006] By adopting the above technical solution, upstream and downstream piles are set up to stabilize the device. Multiple trusses are connected by installation components to facilitate modular assembly. The first and last trusses are connected to the upstream and downstream piles respectively to fix the position of the device. The filling box and opening facilitate the addition of filling material. The sliding rail and slider cooperate to make the filling pipe movable, which is convenient for filling material to different positions. The detachable filling pipe can be removed after filling is completed, thereby realizing the rapid sealing of the dam breach.

[0007] Optionally, the packing box has an installation port on the side away from the truss, and the installation port is covered by a first airbag; a second airbag is provided on the side of the packing box with the opening, and the second airbag is connected to the first airbag; a telescopic member is provided at the bottom of the packing box, and the telescopic member is used to compress the second airbag of the adjacent truss.

[0008] By adopting the above technical solution, when multiple trusses are stacked, the expansion joint at the bottom of the upper truss will naturally press against the second airbag of the lower truss; the pressing pressure causes the air or liquid in the second airbag to be forced into the first airbag connected to it, causing the first airbag to expand; the expanded first airbag tightly abuts against the uneven inner wall of the rupture, thereby improving the tightness of the seal.

[0009] Optionally, the telescopic component includes multiple telescopic plates, multiple telescopic sleeves, and multiple telescopic rods. The telescopic sleeves are fixed to the bottom of the stuffing box, and the telescopic rods are movably installed on the telescopic sleeves and fixed to the telescopic plates. The telescopic plates are used to abut against the second airbags of adjacent trusses. The telescopic sleeves are provided with a first spring, and the elastic force of the first spring is used to drive the telescopic rods to move toward the side away from the telescopic sleeves.

[0010] By adopting the above technical solution, the pre-spring force of the first spring will continuously drive the telescopic rod and telescopic plate to extend downward, which can compress the second airbag and make the first airbag abut against the inner wall of the dam.

[0011] Optionally, the truss at the first / last end is rotatably mounted with two semi-rings, which are used to enclose the outer wall of the upstream pile body, and the free ends of the two semi-rings are connected by a first bolt.

[0012] By adopting the above technical solution, after the two semi-rings are closed, a complete ring structure is formed, which encloses the pile in the middle of the two rings; thus connecting the truss and the pile.

[0013] Optionally, the inner wall of the semi-ring is provided with balls, which are used to abut against the outer wall of the upstream pile body.

[0014] By adopting the above technical solution and setting ball bearings, the smoothness of the truss's downward movement under its own weight can be increased.

[0015] Optionally, the outer wall of the packing tube is provided with a mounting ring, which is connected to the slider by a second bolt.

[0016] By adopting the above technical solution, the second bolt can detachably connect the packing tube and the slider, and the second bolt has a simple structure, which improves the ease of installation.

[0017] Optionally, the pontoon is installed at the bottom of the truss, and the pontoon is provided with straps for securing the bottom of the truss.

[0018] By adopting the above technical solution, the pontoons and trusses can be connected using straps, thereby improving installation efficiency.

[0019] Optionally, a rubber sheet is provided on the side of the stuffing box away from the truss, and a gap exists between the rubber sheet and the stuffing box to form a water-filling cavity; a second spring is provided in the water-filling cavity, and the elastic force of the second spring is used to drive the rubber sheet to move toward the side away from the stuffing box.

[0020] By adopting the above technical solution, the elastic force of the second spring will push the rubber sheet outward in advance, so that it initially contacts the inner wall of the rupture; and after the packing box enters the river water, water enters the filling cavity, the water pressure in the filling cavity increases, and an outward pushing force is applied from the inside of the rubber sheet, pressing the rubber sheet more tightly against the inner wall of the rupture.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Multiple trusses are connected by installation components for easy modular assembly. The first and last trusses are connected to the upstream and downstream piles respectively to fix the device position. The filling box and opening facilitate the addition of filling material. The sliding rail and slider cooperate to make the filling pipe movable, which is convenient for filling to different positions. The detachable filling pipe can be removed after filling is completed, thereby realizing the rapid sealing of the dam breach. 2. When multiple trusses are stacked, the expansion joints at the bottom of the upper truss will naturally press against the second airbag of the lower truss; the compression pressure forces the air or liquid in the second airbag into the first airbag connected to it, causing the first airbag to expand; the expanded first airbag tightly abuts against the uneven inner wall of the rupture, thereby improving the tightness of the seal.

[0024] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0025] Example 1: This application discloses a rapid sealing truss 31 device for filling dam breaches.

[0026] Reference Figure 1 A rapid sealing truss 31 device for filling dike breaches includes an upstream pile 1, a downstream pile 2, and a truss assembly 3. The upstream pile 1 and the downstream pile 2 are respectively located on the side of the upstream dike and the downstream dike closest to the water body. The two ends of the truss assembly 3 are respectively connected to the upstream pile 1 and the downstream pile 2. This structure enables the entire device to be stably installed at the dike breach, thereby blocking the water flow.

[0027] The truss assembly 3 includes multiple trusses 31 and mounting components 32 for connecting the trusses 31. The trusses 31 are generally made of high-strength metal materials, such as steel, and are typically frame structures with good strength and stability. The mounting components 32 can be bolts, nuts, or other connectors, which securely connect adjacent trusses 31 together. In this application, mounting holes are pre-drilled at the connection points of the trusses 31, bolts are passed through the mounting holes, and then nuts are tightened, thus completing the connection of two trusses 31. The presence of the mounting components 32 allows multiple trusses 31 to be combined into a single unit, facilitating flexible assembly according to the size and shape of the joint.

[0028] Simultaneously refer to Figure 2 The trusses 31 located at the beginning and end are respectively connected to the upstream pile 1 and the downstream pile 2. In this embodiment, two semi-rings 33 are rotatably installed on the trusses 31 located at the beginning / end. The two semi-rings 33 are used to enclose the outer wall of the upstream pile 1. The free ends of the two semi-rings 33 are connected by the second bolt 45. The semi-rings 33 are generally made of metal, and their inner walls can be provided with balls 35. The balls 35 are used to abut against the outer wall of the upstream pile 1.

[0029] During installation, the two semi-rings 33 are first opened and placed on the upstream pile body 1. Then, the free ends of the semi-rings 33 are connected with the second bolt 45. At this time, the ball bearings 35 are in contact with the outer wall of the pile body, which not only provides support but also reduces friction, making the truss 31 rotate more smoothly.

[0030] Reference Figure 3 and Figure 4 A stuffing box 4 is provided on one side of the truss 31, and the stuffing box 4 has an opening on its upper side. The stuffing box 4 is usually welded from metal plates, and its shape can be cuboid or cube. The opening design facilitates the addition of filler material into the box, which can be heavy objects such as stones or sandbags. By adding heavy objects into the stuffing box 4, the weight of the truss 31 is increased, making it better able to resist the impact of water flow.

[0031] Reference Figure 5 A slide rail 41 is provided on one side of the stuffing box 4, and a slider 42 is provided on the slide rail 41. The slide rail 41 is generally made of channel steel or I-beam steel, and its surface is smoothed to reduce friction between the slider 42 and the slide rail 41. The slider 42 can be a metal block with a groove inside that matches the slide rail 41, allowing it to slide freely on the slide rail 41. The slider 42 is provided with a detachable stuffing tube 44, which is used to add stuffing to the stuffing box 4.

[0032] It should be noted that when two trusses 31 are connected, the sliders 42 of the two adjacent trusses 31 abut against each other, so that the sliders 42 can slide from one truss 31 to the adjacent truss 31. The packing tube 44 is generally made of plastic or metal, and its outer wall is provided with a mounting ring 43, which is connected to the slider 42 by a second bolt 45. This structure allows the packing tube 44 to move on the slide rail 41 with the slider 42, facilitating the addition of packing to different positions in the packing box 4. When it is necessary to add packing to the packing box 4, the packing tube 44 is connected to an external packing conveying device, and then the slider 42 is pushed to move the packing tube 44 to the position where packing needs to be added, and the packing is conveyed into the box through the opening.

[0033] Reference Figure 3 and Figure 4 The stuffing box 4 has an installation port on the side away from the truss 31, and the installation port is covered by the first airbag 5. The first airbag 5 is generally made of rubber and has good elasticity and sealing performance. The stuffing box 4 has a second airbag 51 on the side with the opening, and the second airbag 51 is connected to the first airbag 5.

[0034] Reference Figure 6The telescopic component 6 includes multiple telescopic plates 61, multiple telescopic sleeves 62, and multiple telescopic rods 63. The telescopic sleeves 62 are fixed to the bottom of the stuffing box 4. The telescopic rods 63 are movably installed on the telescopic sleeves 62 and fixed to the telescopic plates 61. The telescopic plates 61 are used to abut against the second airbags 51 of the adjacent trusses 31. The telescopic sleeves 62 are provided with a first spring 64. The elastic force of the first spring 64 is used to drive the telescopic rods 63 to move away from the telescopic sleeves 62.

[0035] When the upper truss 31 device sinks and stacks onto the lower truss 31, the telescopic plate 61 will squeeze the second airbag 51 on the lower truss 31, causing the second airbag 51 to expand further and come into contact with the inner wall of the rupture, thereby improving the sealing and integrity of the device.

[0036] The truss 31 is equipped with detachable pontoons 7. The pontoons 7 are generally made of plastic or rubber and have good buoyancy. The pontoons 7 are installed at the bottom of the truss 31 and are equipped with straps for securing the bottom of the truss 31. During installation, the pontoons 7 provide buoyancy, making it easier to move and install the truss 31 on the water surface.

[0037] Once the device is installed and a weight is added to the stuffing box 4, the float 7 can be deflated and disassembled. The device will sink under its own weight, thus sealing the breach.

[0038] The working steps of the filling-type dam breach rapid sealing truss 31 device of this application are as follows: S1, upstream pile 1 and downstream pile 2 are respectively implanted on the side of the upstream and downstream dikes near the water body at the breach.

[0039] S2, connect multiple trusses 31 through installation components 32 to form truss components 3; connect the buoys 7 to the bottom of the trusses 31 using straps; then install the truss components 3 on the water surface by hoisting; and rotate the trusses 31 located at the head and tail ends to the upstream and downstream piles 2 through semi-rings 33.

[0040] S3, the packing tube 44 with the mounting ring 43 is installed on the slider 42 by the second bolt 45, and the packing tube 44 is connected to the external packing conveying equipment; push the slider 42 to move the packing tube 44 to the position where the packing box 4 needs to be filled, and add heavy objects such as stones and sandbags into the packing box 4.

[0041] S4. After the packing plate is filled with packing material, remove the float 7 and sink the device into the water to seal it. The number of stacked truss devices according to the breach will play the role of sealing the breach.

[0042] The implementation principle of Embodiment 1 of this application is as follows: Multiple trusses 31 are connected by mounting components 32 for easy modular assembly. The first and last trusses 31 are connected to the upstream and downstream piles 2 respectively to fix the device position. The filling box 4 and opening facilitate the addition of filling material. The sliding rail 41 and slider 42 cooperate to make the filling tube 44 movable, which is convenient for filling material to different positions. The detachable filling tube 44 is convenient for maintenance and replacement. The detachable float 7 is convenient for installation or removal as needed. The auxiliary device floats or sinks in the water, thereby realizing the rapid sealing of the dam breach.

[0043] Example 2: This application discloses a rapid sealing truss 31 device for filling dam breaches.

[0044] Reference Figure 7 The difference between Embodiment 2 and Embodiment 1 is that a rubber sheet is provided on the side of the stuffing box 4 away from the truss 31, and a gap exists between the rubber sheet and the stuffing box 4 to form a water-filling cavity 82. A second spring 81 is provided in the water-filling cavity 82, and the elastic force of the second spring 81 is used to drive the rubber sheet to move toward the side away from the stuffing box 4.

[0045] The implementation principle of Embodiment 2 of this application is as follows: The elastic force of the second spring 81 will push the rubber sheet outward in advance, so that it initially contacts the inner wall of the rupture; and after the stuffing box 4 enters the river water, water enters the filling chamber 82, the water pressure in the filling chamber 82 increases, and an outward pushing force is applied from the inside of the rubber sheet, pressing the rubber sheet more tightly against the inner wall of the rupture.

[0046] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
