Description

Technical Field

[0001] This utility model relates to the field of cofferdam technology, specifically to a corridor-type quick-assembly and disassembly cofferdam. Background Technology

[0002] As a major project concerning people's livelihood, damage to the lining slabs of water supply channels during operation can affect the smooth operation of the project to a certain extent. Repairing the damaged parts of the channel lining slabs will cause great social impact and huge economic losses. Therefore, the damaged parts of the channel lining slabs must be repaired while maintaining the flow.

[0003] Chinese patent CN209989827U discloses a rapid-assembly and disassembly combined cofferdam of a river channel slope-supporting corridor type. The cofferdam body comprises an inlet section, a middle section, and a stop section, connected together by connecting flanges and flange rubber gaskets. The inlet section has first steel wire ropes fixedly installed on both sides of its front, connected to ground anchors placed on the riverbank. The stop section has second steel wire ropes fixedly installed on both sides, connected to the rollers of a winch on the riverbank. The bottom surface of the inlet section is higher than the water level. First, second, and third high-pressure water bladders are sequentially connected via first, second, and third water-filling pipes. This invention features a novel and unique structure, is easy to install and use, and provides excellent results. It can effectively repair damaged channel slopes without interrupting water supply, resulting in high work efficiency.

[0004] However, in the above technical solution, water flow is only prevented from entering the cofferdam by sealing the first, second, and third high-pressure water bladders by connecting them sequentially through the first, second, and third water filling pipes. However, in this device, the cofferdam body is composed of the inlet section cofferdam body, the middle section cofferdam body, and the plug section cofferdam body connected together by connecting flanges and flange rubber gaskets. When the flanges are connected in the water and are subjected to continuous impact from the water flow, the bolt preload may gradually decrease, leading to loosening of the flanges and water leakage. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a corridor-type quick-assembly and disassembly cofferdam.

[0006] The technical solution of this utility model is as follows: A corridor-type quick-assembly and disassembly combination cofferdam includes a cofferdam body, which is composed of an inlet section cofferdam, a middle section cofferdam, and a plug section cofferdam, which are connected by flanges. A movable component is connected to the cofferdam body. A waterproof component is connected to the cofferdam body, and two waterproof components are arranged in parallel. The waterproof components are located at the connection between the inlet section cofferdam and the middle section cofferdam, and at the connection between the middle section cofferdam and the plug section cofferdam. The waterproof component includes a protective plate and a sealing plate. Multiple protective plates are pre-embedded at the ends of the inlet section cofferdam, the middle section cofferdam, and the plug section cofferdam that are close to each other. The sealing plate is slidably connected to the protective plate. The sealing plate is composed of multiple arc-shaped plates that are spliced ​​together. When the protective component is in use, the arc-shaped plates slide and splice between the protective plates to form the sealing plate. The sealing plate and the arc-shaped plates combine to form a waterproof space.

[0007] Preferably, the waterproof component also includes baffles, two of which are symmetrically arranged. The baffles are slidably connected in the grooves opened on the opposite side of the protective plate, and one side of the baffle is slidably connected to the arc plate. There are multiple fixing bolts, which pass through the baffles and are connected to the cofferdam.

[0008] Preferably, dovetail grooves are provided on the protective plates of the inlet section cofferdam, the middle section cofferdam and the end section cofferdam on opposite sides, and dovetail blocks that cooperate with the dovetail grooves are connected to the sealing plates.

[0009] Preferably, the intermediate section of the cofferdam is composed of multiple identical cofferdam flanges connected together.

[0010] Preferably, both ends of the arc-shaped plate are provided with grooves, and a corrugated sealing strip is connected in the groove.

[0011] Preferably, observation windows are provided on any number of curved plates.

[0012] Preferably, the movable component consists of a support frame, wheels, and a telescopic device. Multiple parallel support frames are connected to the opening section cofferdam, the intermediate section cofferdam, and the end section cofferdam, respectively. One end of the telescopic device is connected to the support frame, and the other end of the telescopic device is connected to the wheels.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] In this invention, while the inlet section cofferdam, the intermediate section cofferdam, and the end section cofferdam are assembled into the main body of the cofferdam by flanges, the waterproof components installed between the inlet section cofferdam and the intermediate section cofferdam, and between the intermediate section cofferdam and the end section cofferdam, can further improve the waterproof effect. A sealed space is formed by baffles, protective plates, and sealing plates to seal the flange and bolts for protection, so that the impact of external water flow cannot directly contact the flange. In the event of leakage caused by accidental vibration of the flange, the sealed space will also add a layer of protection to reduce the occurrence of water seepage. Attached Figure Description

[0021] like Figures 1-4 As shown, the present invention proposes a corridor-type quick-assembly and disassembly combination cofferdam, including a cofferdam body 1, a movable component 5 and a waterproof component. The cofferdam body 1 is composed of an inlet section cofferdam 2, an intermediate section cofferdam 3 and a plug section cofferdam 4, which are connected by flanges. The movable component 5 is connected to the cofferdam body 1.

[0022] In an optional embodiment, the movable component 5 consists of a support frame 14, wheels 15, and a telescopic device 16. Multiple parallel support frames 14 are connected to the inlet section cofferdam 3, the intermediate section cofferdam 3, and the end section cofferdam 4, respectively. One end of the telescopic device 16 is connected to the support frame 14, and the other end is connected to the wheels 15. The telescopic device 16 may be, but is not limited to, a hydraulic cylinder, which is equipped with a matching hydraulic pump and other equipment. A waterproof component is connected to the main body 1 of the cofferdam. Two waterproof components are arranged in parallel, with the waterproof component located at the inlet. At the connection points of section cofferdam 2 and intermediate section cofferdam 3, and at the connection points of intermediate section cofferdam 3 and end section cofferdam 4, the waterproofing components include protective plates 6 and sealing plates 7. Multiple protective plates 6 are pre-embedded at the ends of the sections connected to the inlet section cofferdam 2, intermediate section cofferdam 3, and end section cofferdam 4 that are close to each other. The sealing plates 7 are slidably connected to the protective plates 6. The sealing plates 7 are composed of multiple arc-shaped plates 8 that are spliced ​​together. When the protective components are in use, the arc-shaped plates 8 slide and splice between the protective plates 6 to form the sealing plates 7. The sealing plates 7 and the arc-shaped plates 8 combine to form a waterproof space.

[0023] Example 2

[0024] like Figures 2-4As shown, this utility model proposes a corridor-type quick-assembly and disassembly combination cofferdam. Compared with Embodiment 1, this embodiment describes the detailed structure of the waterproof component. The waterproof component also includes baffles 9 and fixing bolts 10. Two baffles 9 are symmetrically arranged and are slidably connected in the grooves opened on the opposite side of the protective plate 6. One side of the baffle 9 is slidably connected to the arc-shaped plate 8. Multiple fixing bolts 10 are distributed and pass through the baffles 9 to connect with the cofferdam. Here, the cofferdam refers to the inlet section cofferdam 2, the middle section cofferdam 3, and the end section cofferdam 4, all of which are cofferdams.

[0025] In an optional embodiment, dovetail grooves 11 are provided on the protective plates 6 of the inlet section cofferdam 2, the intermediate section cofferdam 3 and the end section cofferdam 4 on opposite sides, and dovetail blocks 12 that cooperate with the dovetail grooves 11 are connected to the sealing plate 7.

[0026] In an optional embodiment, the intermediate section of the cofferdam 3 is composed of multiple identical cofferdam flanges connected together;

[0027] In an optional embodiment, grooves are provided at both ends of the arc plate 8, and a corrugated sealing strip 13 is connected in the grooves; the corrugated sealing strip 13 is made of, but is not limited to, rubber material, and the high and low points of the corrugated sealing strip 13 will deform under external force, thereby achieving sealing through deformation.

[0028] In one optional embodiment, any plurality of curved plates 8 are provided with observation windows; the observation windows are typically used to observe the device.

[0029] In summary, when using this utility model, before installing the cofferdam, guide rails, traction equipment, and fixing points for restricting the movement of the traveling wheels 15 are pre-installed on the riverbank slope. During installation, the end section cofferdam 4 is hoisted onto the slope to mate with the guide rails, and then the middle section cofferdam 3 and the inlet section cofferdam 2 are installed sequentially, connected by flanges. When adjacent cofferdams are connected, a baffle 9 is connected to the two adjacent cofferdams by fixing bolts 10. At the same time, the arc-shaped plate 8 is connected to the protective plate 6 by the dovetail groove 11 and the dovetail block 12. When multiple arc-shaped plates 8 come into contact with each other, the corrugated sealing strips 13 come into contact with each other to enhance the sealing effect. At this time, multiple arc-shaped plates 8 are spliced ​​together to form a sealing plate 7, and then another baffle 9 is fixed. The baffle 9, the protective plate 6 and the sealing plate 7 form a sealed space to seal the flange and bolts for protection. After its installation, the fence is moved along the guide rail by traction equipment or manual labor and other equipment. At this time, due to the action of the telescopic device 16, there is a gap between the rubber protective pad on the main body of the cofferdam 1 and the slope, and water will enter into it. Then the telescopic device 16 retracts to make the protective pad close to the slope. The telescopic device 16 makes the main body of the cofferdam 1 stick tightly to the slope, and then the water in the main body of the cofferdam 1 is extracted. After the extraction is completed, the staff can enter it to work.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
