[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 As shown:

[0026] A slope steel cofferdam for local maintenance of a lined channel comprises a channel body 1.

[0027] In this implementation scheme: some local cofferdams will have a certain impact on channel water delivery during the repair period, and due to the large size of the cofferdam, it is troublesome to install and remove, and it is difficult to clean the channel after removal. Combined with the use, this problem is obviously a real and difficult problem to solve. In view of this, in order to solve this technical problem, the splicing component 2 and the support component 3 are added to the application document.

[0028] More specifically:

[0029] like Figure 1-Figure 4 As shown:

[0030] In combination with the above content, the splicing component 2 includes an inclined steel plate 22 symmetrically installed on the slope surface of the channel body 1, and a water retaining plate 21 is installed on the side of the inclined steel plate 22. A T-shaped plug-in block 24 is fixedly connected to one side of the surface of the water retaining plate 21, and a slot 25 matching the plug-in block 24 is provided on the other side of the surface of the water retaining plate 21. A T-shaped block 27 is slidably connected inside the water retaining plate 21, and a slot 23 is provided on the surface of the plug-in block 24. Two bidirectional screw rods 210 are symmetrically rotatably connected inside the water retaining plate 21, and the two bidirectional screw rods 210 are connected at the first position. A moving block 29 is symmetrically screwed on the surface of the bidirectional screw rod 210, and a connecting rod 28 is hinged between the block 27 and the moving block 29.

[0031] In this embodiment: when the steel cofferdam is in use, the size of the cofferdam is first adjusted according to the size of the channel and the location that needs maintenance, and the cofferdam is assembled by splicing multiple groups of water retaining plates 21 and inclined steel plates 22. The two groups of water retaining plates 21 are spliced ​​by inserting the plug blocks 24 on the water retaining plates 21 into the slots 25 on the surfaces of the adjacent water retaining plates 21. Then, the moving block 29 is driven to move by rotating the bidirectional screw rod 210. The moving block 29 will push the block 27 on one side to move through the connecting rod 28, so that the block 27 is stuck in the slot 23, thereby limiting the position of the plug block 24 and improving the stability of the splicing of the water retaining plates 21.

[0032] It should be noted that waterproof sealing pads are symmetrically arranged on both sides of the surface of the plug block 24, which can improve the sealing effect of the splicing of the water retaining plate 21. The surface of the inclined steel plate 22 is provided with a water retaining plate 21 that is the same as the water retaining plate 21, which is convenient for splicing the inclined steel plate 22 and the water retaining plate 21, and the surface of the water retaining plate 21 located at the corner is vertically provided with plug blocks 24, which splices the cofferdam into a U-shaped structure.

[0033] Going further:

[0034] like Figure 1-Figure 4 As shown:

[0035] In order to facilitate the disassembly of the cofferdam, in an optional embodiment: the top end of the bidirectional screw rod 210 passes through the interior of the water baffle 21 and is fixedly connected to a rotating member 211 arranged on the surface of the water baffle 21, and an insertion groove A is provided on the side of the surface of the water baffle 21 close to the rotating member 211; the top ends of the water baffle 21 and the inclined steel plate 22 are fixedly connected with a lifting ear 26; the bottom surfaces of the water baffle 21 and the inclined steel plate 22 are fixedly connected with a rubber strip.

[0036] In this embodiment: after the cofferdam is spliced, the crane can lift the cofferdam through the lifting lug 26 and then sink it into the channel to reduce the impact on the water supply of the channel. The accumulated water in the working area can be discharged through the water pump to expose the channel surface for maintenance. When the cofferdam is dismantled, the cofferdam is filled with water, and then the rotating part 211 is reversed to drive the block 27 to slide out of the slot 23, thereby releasing the limit on the insert block 24, and each set of water retaining plates 21 and inclined steel plates 22 can be lifted separately through the lifting lug 26 for dismantling.

[0037] More specifically:

[0038] like Figure 1-Figure 4 As shown:

[0039] In combination with the above content, a support assembly 3 is provided on the side of the water baffle 21, and the support assembly 3 includes a bottom plate 34 hinged at the bottom end of the side of the water baffle 21, a screw rod 31 rotates inside the water baffle 21, a slider 32 is screwed on the surface of the screw rod 31, and a support rod 33 is hinged between the slider 32 and the bottom plate 34; the top end of the screw rod 31 passes through the inside of the water baffle 21 and is rotatably connected to a handle set on the water baffle 21, and an insertion groove B is opened on the side of the surface of the water baffle 21 close to the handle.

[0040] In this embodiment: when the steel cofferdam is in use, the size of the cofferdam is first adjusted according to the size of the channel and the position that needs to be repaired, and the cofferdam is assembled by splicing multiple groups of water retaining plates 21 and inclined steel plates 22. The two groups of water retaining plates 21 are spliced ​​by inserting the plug-in blocks 24 on the water retaining plates 21 into the slots 25 on the surfaces of the adjacent water retaining plates 21. Then, the moving block 29 is driven to move by rotating the bidirectional screw rod 210. The moving block 29 will push the card block 27 on one side to move through the connecting rod 28, so that the card block 27 is stuck in the card slot 23, thereby limiting the position of the plug-in block 24 and improving the stability of the splicing of the water retaining plates 21. After the splicing of the cofferdam is completed, the crane can lift the cofferdam through the lifting lugs 26 and then sink it into the channel to reduce the impact on the water supply of the channel. The accumulated water in the working area can be discharged by a water pump to expose the maintenance channel surface. When the cofferdam is dismantled, the cofferdam is filled with water, and then the rotating member 211 is reversed to drive the block 27 to slide out from the inside of the slot 23, and the limit of the insert block 24 is released. Each group of water retaining plates 21 and inclined steel plates 22 can be lifted separately by the lifting ears 26 for dismantling. After the cofferdam is installed, the slider 32 is driven to move downward by rotating the screw rod 31, and then the slider 32 will push the bottom plate 34 to unfold through the support rod 33, and the water retaining plate 21 is supported by the support rod 33 and the bottom plate 34, thereby increasing the stability of the cofferdam installation, and the bottom plate 34 and the water retaining plate 21 can be folded by pulling the support rod 33 by reversing the screw rod 31, thereby reducing the area occupied by the water retaining plate 21 and facilitating its storage.

[0041] Working principle: After the cofferdam is installed, the slider 32 is driven downward by rotating the screw rod 31, and then the slider 32 will push the bottom plate 34 to unfold through the support rod 33, and the water retaining plate 21 is supported by the support rod 33 and the bottom plate 34, thereby increasing the stability of the cofferdam installation, and by reversing the screw rod 31, the bottom plate 34 and the water retaining plate 21 can be pulled to fold through the support rod 33, thereby reducing the area occupied by the water retaining plate 21 and facilitating its storage.

[0042] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
