Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy construction, and particularly relates to a water conservancy construction cofferdam. Background Art

[0002] A cofferdam is a temporary retaining structure used during the construction of permanent water conservancy facilities. Its purpose is to prevent water and soil from entering the construction site, allowing drainage, excavation, and construction within the cofferdam. It is typically used in hydraulic structures and, unless it is part of a formal structure, is typically dismantled after use. The height of the cofferdam is higher than the highest possible water level during construction.

[0003] Chinese utility model patent CN218713175U discloses a water conservancy construction cofferdam structure, including a baffle, a buffer assembly fixedly connected to the front wall of the baffle, the buffer assembly including a buffer plate, a fixed block fixedly connected to the front wall of the baffle, a slide groove is provided in the middle of the fixed block, a coil spring is provided in the slide groove, a limit block is fixedly connected to the buffer plate, and the limit block is slidably arranged in the slide groove. The baffle in the utility model is a structure that can be spliced in multiple pieces, and the first reinforcement assembly and the second reinforcement assembly used for the connection are easy to disassemble. When the connection becomes loose, they can be directly replaced with new ones. At the same time, the buffer assembly in the utility model can play a buffering role to a certain extent when subjected to impact;

[0004] The above design, through the use of multiple groups of components, can add additional buffer components to the cofferdam, which can provide a buffering effect when the cofferdam is impacted by water flow. However, in actual use, both the above design and the existing cofferdam have certain problems. Specifically, when the cofferdam is in use, it needs to be pressed by a pile hammer to allow the cofferdam to enter the riverbed. During the operation of the pile hammer, the upper and lower ends of the cofferdam are respectively impacted by the pile hammer and the rocks in the riverbed. Once these two impact forces exceed the threshold that the cofferdam itself can withstand, the plates in the cofferdam will bend, resulting in the overall blocking and sealing effect of the cofferdam being affected.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0028] Depend on Figure 1 、 Figure 2 and Figure 4 As shown, a water conservancy construction cofferdam includes a guide pile 1 and a protective assembly 2. The guide pile 1 is equidistantly inserted in the riverbed, and the protective assembly 2 is equidistantly arranged in the space surrounded by the guide pile 1. A bearing mechanism 3 is fixedly installed on the top of the protective assembly 2. The bearing mechanism 3 includes a side plate 31, a slide 32, a connecting frame 33 and a bearing block 34. The side plate 31 is fixedly installed on the inner wall of the protective assembly 2, a slide 32 is opened inside the side plate 31, the connecting frame 33 is slidably installed in the slide 32, and the bearing block 34 is fixedly installed on the top of the connecting frame 33.

[0029] During use, a plurality of guide piles 1 are inserted into the riverbed by using a pile hammer to construct the approximate range after the subsequent protection components 2 are spliced. When the protection components 2 need to be installed, the support mechanism 3 is used to assist the protection components 2 in positioning. The support block 34 is installed on the top of the side plate 31 by using the connecting frame 33 and the slide 32. Then, the position of the support block 34 is further processed by the operation of the internal components of the support mechanism 3. Then, the support block 34 is struck back and forth by using a pile hammer, so that the support block 34 is impacted multiple times, pushing the protection components 2 to move into the riverbed. Then, the protection components 2 are used to quickly splice multiple groups of protection components 2 to complete the combination of the cofferdam and achieve stable splicing and installation of the cofferdam.

[0030] By the attached Figure 4As shown, in this embodiment, the bearing mechanism 3 also includes a matching groove 35 and a matching rod 36. The connecting frame 33 and the side plate 31 are jointly provided with a matching groove 35, and the matching rod 36 is threadedly installed in the matching groove 35. During use, the bearing block 34 is stably installed on the top of the protective component 2 through the use of the matching groove 35 and the matching rod 36. When the pile hammer hits the protective component 2, the bearing block 34 will withstand the direct impact of the pile hammer, and through the cooperation of the connecting frame 33 and the side plate 31, the impact force is transmitted to the interior of the protective component 2, allowing the protective component 2 to enter the riverbed.

[0031] By the attached Figure 3 As shown, in this embodiment, the protective component 2 includes a blocking plate 21 and a reinforcement plate 22. The blocking plates 21 are equidistantly arranged in the space surrounded by the guide pile 1, and the reinforcement plates 22 are symmetrically fixed on the side of the blocking plate 21. During use, the blocking plates 21 and the reinforcement plates 22 are used to block the river water on the side. Once multiple groups of blocking plates 21 and reinforcement plates 22 are spliced together, external water sources can be prevented from entering the cofferdam. In subsequent use, it is necessary to add an additional group of spliced blocking plates 21 and reinforcement plates 22 in the space of the already combined blocking plates 21 and reinforcement plates 22, and pour concrete between the two groups of cofferdams to enhance the sealing effect of the equipment itself.

[0032] By the attached Figure 3 As shown, in this embodiment, the protective component 2 also includes a limit plate 23 and a limit block 24. There are two groups of reinforcement plates 22, one group of reinforcement plates 22 has a limit plate 23 fixedly installed on the side, and the other group of reinforcement plates 22 has a limit block 24 fixedly installed on the side. The limit block 24 is slidably connected to the limit plate 23. During use, the use of the limit plate 23 and the limit block 24 assists in splicing multiple groups of blocking plates 21, which facilitates calibration and positioning when the blocking plate 21 is installed.

[0033] By the attached Figure 5 As shown, in this embodiment, the water conservancy construction cofferdam also includes a crushing mechanism 4, and the crushing mechanism 4 includes a connecting block 41, a connecting plate 42, and a crushing end 43. The connecting block 41 is fixedly installed on the bottom end of the inner wall of the blocking plate 21, and the connecting plate 42 is slidably installed inside the connecting block 41. The crushing end 43 is fixedly installed on the bottom end of the connecting plate 42. During use, the crushing end 43 is installed to the bottom end of the protective component 2 through the use of the connecting block 41 and the connecting plate 42. Once the protective component 2 as a whole is impacted by the pile hammer, the crushing end 43 enters the riverbed earlier than the protective component 2 to crush the stones in the riverbed.

[0034] By the attached Figure 5As shown, in this embodiment, the crushing mechanism 4 also includes a reinforcing rod 44, and the reinforcing rod 44 is threadedly installed inside the connecting block 41 and the connecting plate 42. During use, the crushing end 43 is stably installed and positioned by using the reinforcing rod 44 to ensure the stability of the crushing end 43 when in use.

[0035] By the attached Figure 6 As shown, in this embodiment, the water conservancy construction cofferdam also includes a limiting mechanism 5, which includes a connecting block 51, a fixing block 52, a limiting ring 53, a fixing groove 54 and a fixing rod 55. The connecting block 51 is fixedly installed on the side of the blocking plate 21, the fixing block 52 is fixedly installed on the end of the connecting block 51, and the limiting ring 53 is slidably installed inside the fixing block 52. Fixing grooves 54 are equidistantly provided inside the limiting ring 53, and the fixing rod 55 passes through the inner wall of the fixing block 52 and is threadedly connected to the fixing groove 54. During use, multiple groups of protective components 2 are spliced to form a complete cofferdam, and then the limiting rings 53 are respectively installed in the fixing blocks 52 on the sides of the multiple groups of protective components 2, and with the cooperation of the fixing groove 54 and the fixing rod 55, the position of the limiting ring 53 is locked, so that the connection between the multiple groups of protective components 2 is reinforced, thereby ensuring the stability of the cofferdam during use.
