Description

Technical Field

[0001] This utility model relates to a detachable cofferdam structure and belongs to the field of cofferdam technology. Background Technology

[0002] A cofferdam is a temporary retaining structure built in hydraulic engineering projects to construct permanent hydraulic facilities. Its function is to prevent water and soil from entering the construction site, allowing for drainage, excavation of foundation pits, and construction of structures within the cofferdam. It is primarily used in hydraulic engineering structures, and unless it is part of a permanent building, a cofferdam generally needs to be dismantled after use.

[0003] Existing water conservancy construction cofferdams are all connected by welding, which makes them difficult to install quickly and dismantle quickly when needed, thus slowing down the work efficiency of construction workers. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a detachable cofferdam structure, which solves the problem that the existing water conservancy construction cofferdams are all connected by welding, which cannot be installed quickly during installation and is difficult to disassemble quickly when needed, thus delaying the work efficiency of construction personnel.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: a detachable cofferdam structure, including a rectangular frame base, a fixing groove on the top of the base, and cofferdam plates that can be detachably installed inside the fixing groove. Adjacent cofferdam plates are detachably connected by connecting columns, and impact-resistant structures can be detachably installed on several cofferdam plates.

[0006] By adopting the above technical solution, when installing a cofferdam structure, firstly, the base is placed on the foundation of the pre-planned building. Then, all four cofferdam panels are inserted into the fixing grooves. Next, adjacent cofferdam panels are connected by connecting columns. Finally, impact-resistant structures are installed on all four cofferdam panels, thus completing the installation of the cofferdam structure. Compared to welding, the installation of the cofferdam structure using this method is faster, and it can be quickly disassembled when needed, thus improving the work efficiency of construction personnel.

[0007] The present invention is further configured such that: both sides of the cofferdam plate are provided with T-shaped grooves, and both sides of the connecting column are integrally formed with T-shaped protrusions for being inserted into the grooves.

[0008] By adopting the above technical solution, when it is necessary to connect two adjacent cofferdam plates, move the connecting column so that the bottom ends of the two protrusions are aligned with the grooves of the two cofferdam plates respectively. Then move the connecting column towards the direction of the fixed groove so that the two protrusions slide into the two grooves until the bottom surface of the connecting column is in contact with the bottom surface of the fixed groove. This will allow the two protrusions to be completely inserted into the two grooves, and the two cofferdam plates can be connected by the connecting column.

[0009] The present invention is further configured such that: both sides of the connecting column are integrally formed with retaining edges on one side of each of the two protrusions.

[0010] By adopting the above technical solution, after both protrusions are inserted into the two grooves, one side of each of the two retaining edges is respectively attached to one side of each of the two cofferdam plates. At this time, when the connection between two adjacent cofferdam plates is impacted, the retaining edges can withstand part of the impact force, making the connection effect of the connecting column more stable, thereby making the connection between the two cofferdam plates more secure, and thus ensuring a more secure containment effect of the cofferdam plates.

[0011] The present invention is further configured such that: the anti-impact structure includes an anti-impact plate that is slidably and detachably fixed to one side of the cofferdam plate; both ends of the cofferdam plate are integrally formed with a plurality of locking blocks for fixing the anti-impact plate; both sides of the anti-impact plate are integrally formed with fixing blocks; and a fixing cavity is formed between the plurality of locking blocks and the cofferdam plate for the fixing blocks to be inserted.

[0012] By adopting the above technical solution, when it is necessary to reinforce the cofferdam plate, the impact-resistant plate is moved to one side of the cofferdam plate so that the two fixing blocks are aligned with the two upper locking blocks. Then, the two ends of the impact-resistant plate are moved towards the base so that the two fixing blocks are engaged in the two upper fixing cavities. As the impact-resistant plate continues to move downward, the two fixing blocks are engaged in the two lower fixing cavities until the bottom surfaces of the two fixing blocks are in contact with the top surface of the base. This completes the installation of the impact-resistant plate, thereby reinforcing the cofferdam plate, improving its impact resistance, more effectively resisting the effects of water flow, waves, or other external impacts, and extending the service life of the cofferdam plate.

[0013] The present invention is further configured such that: an arc-shaped impact surface is provided on the side of the impact-resistant plate away from the cofferdam plate.

[0014] By adopting the above technical solution, the arc-shaped impact surface is set, and the thickness of the impact plate at the impact point is increased, the impact resistance of the impact plate is further improved, the pressure per unit area is reduced, the impact damage to the impact plate and the cofferdam plate is reduced, and the service life of the cofferdam plate is further extended.

[0015] The present invention is further configured such that: a plurality of connecting blocks I for connecting connecting columns are welded on the outer wall of the base, and a plurality of threaded holes I are opened at one end of each of the plurality of connecting blocks I, and a plurality of threaded holes II are opened on the connecting column, and the plurality of connecting blocks I and the connecting column are detachably connected by bolts I, and the bolts I are threadedly connected in the threaded holes I and the threaded holes II.

[0016] Several connecting blocks 2 for connecting the cofferdam plate are welded on the outer wall of the base. Each of the connecting blocks 2 has a threaded hole 3 at one end. The cofferdam plate has several threaded holes 4. The connecting blocks 2 and the cofferdam plate are detachably connected by bolts 2. The bolts 2 are threaded into the threaded holes 3 and 4.

[0017] Among them, the impact-resistant plate has five threaded holes for bolts to be inserted.

[0018] By adopting the above technical solution, when it is necessary to fix the base and the connecting column, it is only necessary to thread the bolt into the threaded hole one and the threaded hole two to ensure that the connecting column does not come out of the fixing groove and thus does not separate from the base.

[0019] When it is necessary to fix the base and connecting column, simply connect the bolt two threads into the threaded holes three, four and five to ensure that the cofferdam plate does not detach from the fixing groove and thus does not separate from the base.

[0020] The present invention is further configured such that: the bottom of the base is integrally formed with several fixing rods for being driven into the foundation.

[0021] By adopting the above technical solution, when fixing the base, simply insert several fixing rods into the foundation to fix the base on the foundation, ensuring that the base will not move under the impact of water flow or external forces such as wind and waves.

[0022] The beneficial effects of this utility model are as follows: When installing a cofferdam structure, firstly, the base is placed on the foundation of the planned building. Then, all four cofferdam panels are inserted into the fixing grooves. Next, adjacent cofferdam panels are connected by connecting columns. Finally, impact-resistant structures are installed on all four cofferdam panels, thus completing the installation of the cofferdam structure. Compared to welding, the installation of the cofferdam structure using this method is faster, and it can be quickly disassembled when needed, thus improving the work efficiency of construction personnel.

[0028] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific figures 1-4.

[0029] like Figure 1 and Figure 2 As shown, a detachable cofferdam structure includes a rectangular frame base 1, a fixing groove 2 on the top of the base 1, and cofferdam plates 3 that can be detachably installed inside the fixing groove 2. Adjacent cofferdam plates 3 are detachably connected by connecting columns 4, and several cofferdam plates 3 can be detachably installed with impact-resistant structures.

[0030] When installing a cofferdam structure, firstly, the base 1 is placed on the foundation of the planned building. Then, all four cofferdam panels 3 are inserted into the fixing grooves 2. Next, adjacent cofferdam panels 3 are connected by connecting columns 4. Finally, impact-resistant structures are installed on all four cofferdam panels 3, completing the cofferdam structure installation. Compared to welding, this structure allows for faster installation of the cofferdam structure and also enables quick disassembly, improving the efficiency of construction workers.

[0031] like Figure 3 and Figure 4 As shown, T-shaped grooves 5 are provided on both sides of the cofferdam plate 3, and T-shaped protrusions 6 are integrally formed on both sides of the connecting column 4 for inserting into the grooves 5.

[0032] Both sides of the connecting post 4 are integrally formed with flanges 7 on one side of each of the two protrusions 6, and the length of the two flanges 7 is shorter than the length of the connecting post 4.

[0033] When it is necessary to connect two adjacent cofferdam plates 3, move the connecting column 4 so that the bottom ends of the two protrusions 6 are aligned with the grooves 5 of the two cofferdam plates 3 respectively. Then move the connecting column 4 towards the direction of the fixed groove 2 so that the two protrusions 6 slide into the two grooves 5 until the bottom surface of the connecting column 4 is in contact with the bottom surface of the fixed groove 2. This will allow the two protrusions 6 to be completely inserted into the two grooves 5, and the two cofferdam plates 3 can be connected by the connecting column 4.

[0034] After both protrusions 6 are engaged in the two grooves 5, one side of each of the two retaining edges 7 is attached to one side of each of the two cofferdam plates 3. At this time, when the connection between two adjacent cofferdam plates 3 is impacted, the retaining edges 7 can withstand part of the impact force, making the connection of the connecting column 4 more stable, thus making the connection between the two cofferdam plates 3 more secure, and thus ensuring a more secure containment effect of the cofferdam plates 3.

[0035] like Figure 4 As shown, the anti-impact structure includes an anti-impact plate 8 that is slidably and detachably fixed to one side of the cofferdam plate 3. Both ends of the cofferdam plate 3 are integrally formed with several locking blocks 9 for fixing the anti-impact plate 8. Both sides of the anti-impact plate 8 are integrally formed with fixing blocks 10. The locking blocks 9 and the cofferdam plate 3 are all formed with fixing cavities 11 for the fixing blocks 10 to be inserted into.

[0036] An arc-shaped impact surface 12 is provided on the side of the anti-impact plate 8 away from the cofferdam plate 3.

[0037] When reinforcement of the cofferdam plate 3 is required, move the impact-resistant plate 8 to one side of the cofferdam plate 3 so that the two fixing blocks 10 are aligned with the two upper locking blocks 9. Then, move both ends of the impact-resistant plate 8 toward the base 1 so that the two fixing blocks 10 are engaged in the two upper fixing cavities 11. As the impact-resistant plate 8 continues to move downward, the two fixing blocks 10 are engaged in the two lower fixing cavities 11 until the bottom surfaces of the two fixing blocks 10 are in contact with the top surface of the base 1. This completes the installation of the impact-resistant plate 8, thereby reinforcing the cofferdam plate 3, improving its impact resistance, and more effectively resisting the effects of water flow, waves, or other external impacts, thus extending the service life of the cofferdam plate 3.

[0038] The arc-shaped impact surface 12, by increasing the thickness of the impact-resistant plate 8 at the impact point, further improves the impact resistance of the impact-resistant plate 8, reduces the pressure per unit area, reduces the damage to the impact-resistant plate 8 and the cofferdam plate 3, and thus further extends the service life of the cofferdam plate 3.

[0039] like Figure 1 and Figure 2As shown, several connecting blocks 13 for connecting the connecting column 4 are welded on the outer wall of the base 1. One end of each connecting block 13 is provided with a threaded hole 14. Several threaded holes 25 are provided on the connecting column 4. The connecting blocks 13 and the connecting column 4 are detachably connected by bolts 16. The bolts 16 are threaded into the threaded holes 14 and 25.

[0040] Several connecting blocks 17 for connecting the cofferdam plate 3 are welded on the outer wall of the base 1. Each of the connecting blocks 17 has a threaded hole 18 at one end. The cofferdam plate 3 has several threaded holes 19. The connecting blocks 17 and the cofferdam plate 3 are detachably connected by bolts 20. The bolts 20 are threaded into the threaded holes 18 and 19.

[0041] Among them, the impact plate 8 has a threaded hole 24 for bolt 20 to be inserted.

[0042] When it is necessary to fix the base 1 and the connecting column 4, simply thread the bolt 16 into the threaded hole 14 and the threaded hole 25 to ensure that the connecting column 4 does not come off the fixing groove 2 and thus does not separate from the base 1.

[0043] When it is necessary to fix the base 1 and the connecting column 4, simply thread the bolt 20 into the threaded hole 18, the threaded hole 19 and the threaded hole 24 to ensure that the cofferdam plate 3 does not detach from the fixing groove 2 and thus does not separate from the base 1.

[0044] like Figure 1 As shown, the bottom of the base 1 is integrally formed with several fixing rods 21 for being driven into the foundation.

[0045] When fixing the base 1, simply insert several fixing rods 21 into the foundation to fix the base 1 on the foundation, ensuring that the base 1 will not move under the impact of water flow or external forces such as wind and waves.

[0046] like Figure 1 As shown, hooks 22 are fixed to both ends of the top of several cofferdam slabs 3 and the top of the connecting columns 4.

[0047] The hooks 22 provide a stable lifting point, facilitating the movement of the cofferdam plate 3 and the connecting column 4. Fixing two hooks 22 to the top of the cofferdam plate 3 ensures its balance and stability during movement, thereby improving the efficiency and quality of the lifting operation, while also making the operation more convenient and safer.

[0048] like Figure 1 As shown, guide surfaces 23 are provided on the outer sides of the base 1.

[0049] When the water flow washes over the outer wall of the base 1, the guide surface 23 directs the impact force of the water flow to the anti-impact plate 8, thereby reducing the direct impact of the water flow on the bottom of the base 1 and reducing the gap between the bottom of the base 1 and the foundation.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
