Description

Technical Field

[0001] The utility model relates to the technical field of cofferdams, in particular to a detachable cofferdam structure. Background Art

[0002] The main function of the cofferdam is to provide temporary enclosure in the construction of water conservancy projects to prevent water and soil from entering the construction site of the building. The cofferdams in the prior art are divided into two types: fixed specifications and customized specifications, which need to be selected according to different construction scopes. Since the time cost of customizing cofferdams is high, construction units mostly choose cofferdams of fixed specifications. However, due to the randomness of the construction scope, it is often impossible to make the size specifications of the construction scope and the cofferdam exactly the same, resulting in low applicability of the cofferdam, thus affecting the construction effect. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides a detachable cofferdam structure, which has the advantage of being able to arbitrarily combine and splice the cofferdam plates in the vertical and horizontal directions, and has a high applicability. It solves the problem in the prior art that due to the randomness of the construction scope, the construction scope is often unable to be exactly the same as the size specification of the cofferdam, resulting in low applicability of the cofferdam, thus affecting the construction effect.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A detachable cofferdam structure comprises a cofferdam plate as a structural main body, a vertical combination mechanism for height splicing of a plurality of cofferdam plates is arranged on the cofferdam plate, horizontal combination mechanisms for width splicing of a plurality of cofferdam plates are arranged at both ends of the cofferdam plate, a buffer mechanism for mitigating the impact force of water flow is arranged on one side of the cofferdam plate, the vertical combination mechanism comprises a trapezoidal block a fixedly connected to the top of the cofferdam plate, a trapezoidal slot a for snapping with the trapezoidal block a is provided at the bottom of the cofferdam plate, the horizontal combination mechanism comprises two groups of trapezoidal slots b symmetrically arranged on both sides of the cofferdam plate, trapezoidal blocks b for snapping with the trapezoidal slots b are fixedly connected at both ends of the cofferdam plate, trapezoidal through grooves are provided at the bottoms of the two trapezoidal blocks b, an I-shaped block is snapped in the trapezoidal through groove, and a fixed block is fixedly connected to the bottom of the I-shaped block.

[0006] Preferably, the thickness of the fixing block is the same as the height of the bottom wall of the trapezoidal slot b from the horizontal plane.

[0007] Preferably, the shape formed by the two adjacent trapezoidal through grooves is the same as the shape and size of the I-shaped clamping block.

[0008] Preferably, the buffer mechanism comprises a connecting plate installed on one side of the cofferdam plate, and a plurality of equidistantly distributed water flow grooves are provided on one side of the connecting plate.

[0009] Preferably, each group of the trapezoidal slots b includes two trapezoidal slots b respectively located on both sides of the cofferdam plate.

[0010] Preferably, the surfaces of the cofferdam plates and the connecting plates are coated with anti-corrosion materials.

[0011] By means of the above technical solution, the utility model provides a detachable cofferdam structure, which has at least the following beneficial effects:

[0012] 1. The utility model enables the cofferdam plates to be freely combined and spliced ​​by arranging a vertical combination mechanism and a horizontal combination mechanism. The height of the cofferdam plates can be superimposed by connecting the trapezoidal clamping blocks a and the trapezoidal clamping grooves a on the two cofferdam plates.

[0013] 2. The utility model provides a buffer mechanism to alleviate the external water flow impact force on the device during use. The water flow is hindered to a certain extent through the water flow trough, thereby slowing down the speed of the water flow, causing diversion when the water flows through the water flow trough, thereby achieving the effect of slowing down the water flow and increasing the service life of the device.

[0021] 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.

[0022] Existing cofferdams are divided into two types: fixed specifications and customized specifications. They need to be selected according to different construction scopes. If a cofferdam of corresponding specifications is customized, the time and cost consumed are relatively high. Most construction units choose cofferdams of fixed specifications. However, due to the uncertainty of the construction scope in different constructions, it is often impossible to ensure that the size specifications of the construction scope and the cofferdam are exactly the same, which can easily result in poor cofferdam protection effect. The following describes a detachable cofferdam structure provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] In order to solve the problem that the construction scope and the size of the cofferdam cannot be completely the same due to the randomness of the construction scope in the existing technology, Figure 1 and Figure 2 as well as Figure 3 As shown, this embodiment proposes a detachable cofferdam structure, which can assemble and disassemble the cofferdam plates according to different construction ranges, and has the advantage of high applicability. The cofferdam structure uses the cofferdam plate 1 as the main structure, and a vertical combination mechanism 2 for splicing multiple cofferdam plates 1 in height is arranged on the cofferdam plate 1, and a horizontal combination mechanism 3 for splicing multiple cofferdam plates 1 in width is arranged at both ends of the cofferdam plate 1. At the same time, a buffer mechanism 4 for mitigating the impact force of external water flow is arranged on one side of the cofferdam plate 1.

[0025] Since the cofferdam height and width required for different construction scopes are not the same, and the cost of custom-made cofferdams is too high, a vertical combination mechanism 2 capable of stacking the heights of multiple cofferdam plates 1 and a horizontal combination mechanism 3 capable of stacking the widths of multiple cofferdam plates 1 are proposed. The two cooperate to meet the required dimensions of different construction scopes. The vertical combination mechanism 2 includes a trapezoidal block a201 fixedly connected to the top of the cofferdam plate 1, and a trapezoidal slot a202 for connecting with the trapezoidal block a201 is provided at the bottom of the cofferdam plate 1. The horizontal combination mechanism 3 includes two groups of trapezoidal slots b301 symmetrically arranged on both sides of the cofferdam plate 1, and each group of trapezoidal slots b301 includes two trapezoidal slots b301 respectively located on both sides of the cofferdam plate 1. Both ends of the cofferdam plate 1 are fixedly connected with a trapezoidal slot a202 for connecting with the trapezoidal block a201. The trapezoidal blocks b302 are connected to the slots b301, and the bottoms of the two trapezoidal blocks b302 are both provided with trapezoidal through grooves 303. An I-shaped block 305 is connected in the trapezoidal through grooves 303, and the bottom of the I-shaped block 305 is fixedly connected with a fixed block 304. By connecting the trapezoidal blocks a201 and the trapezoidal slots a202 on different cofferdam plates 1, the vertical heights of the two cofferdam plates 1 are superimposed. By connecting the trapezoidal through grooves 303 and the I-shaped blocks 305 on the two cofferdam plates 1, the lengths of the cofferdam plates 1 can be superimposed. By combining the trapezoidal slots b301 and the trapezoidal blocks b302 on different cofferdam plates 1, the four cofferdam plates 1 can be combined into a closed space, which is suitable for the enclosure of different construction spaces, thereby greatly improving the applicability of the device.

[0026] The thickness of the fixed block 304 is the same as the height of the bottom wall of the trapezoidal slot b301 from the horizontal plane, and the shape formed by the two adjacent trapezoidal through grooves 303 is the same as the shape and size of the I-shaped block 305, so that the two trapezoidal blocks b302, the I-shaped block 305 and the fixed block 304 can be tightly connected, so that the two cofferdam plates 1 will not form a large gap during the horizontal combination process, preventing water from flowing into the interior.

[0027] Embodiment 2:

[0028] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem in the prior art that due to the randomness of the construction scope, the size specifications of the construction scope and the cofferdam are often not exactly the same, resulting in low applicability of the cofferdam, thereby affecting the construction effect. However, during the use of the device, the external water flow will continuously cause a certain impact effect on the cofferdam. If it is not buffered, the service life of the device will be greatly reduced.

[0029] Since the cofferdam plate 1 is mostly set in the water, under long-term protection, the impact of the water flow will continuously reduce the service life of the cofferdam plate 1. Figure 1 and Figure 4As shown, a buffer mechanism 4 capable of effectively mitigating the impact force of water flow is proposed, the buffer mechanism 4 includes a connecting plate 401 installed on one side of the cofferdam plate 1, a plurality of equidistantly distributed water flow grooves 402 are opened on one side of the connecting plate 401, and the connecting plate 401 is installed on the surface of the cofferdam plate 1. The water flow is hindered to a certain extent by the plurality of water flow grooves 402, thereby slowing down the speed of the water flow, so that the water flow will be diverted when flowing through the water flow grooves 402, thereby achieving the effect of slowing down the water flow, thereby achieving the effect of mitigating the impact force and improving the service life of the device.

[0030] The surfaces of the cofferdam plate 1 and the connecting plate 401 are coated with anti-corrosion materials. Commonly used coating materials include epoxy resin, polyurethane, acrylic acid, etc., which prevent water and air from corroding the cofferdam and further improve the service life of the device.

[0031] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
