Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering construction, specifically a cofferdam structure for water conservancy engineering construction. Background Technology
[0002] In traditional water conservancy construction, cofferdam operations are carried out on the water source construction section. During the operation, multiple sets of piles need to be inserted into the water. Hydraulic jacks are generally used to insert the piles. During the insertion, constant observation is required. If there is any negligence, it is difficult to ensure the levelness after insertion.
[0003] To address the aforementioned issues, patent document CN221193398U discloses a cofferdam structure for water conservancy engineering construction, comprising: a pile, wherein the pile is an integral shell structure and an inclined plug integrally formed therewith is provided at the bottom end of the pile; a force-bearing block, wherein the force-bearing block is integrally mounted on the pile, and a first guide mechanism is provided on both sides of the force-bearing block, and the force-bearing block moves linearly up and down within the pile through the first guide mechanism; and a limiting mechanism, wherein the limiting mechanism includes a limiting block, a sliding opening is provided on one outer wall of the pile, the limiting block is integrally slidably mounted within the sliding opening, a reset mechanism is provided on the outer wall of the limiting block, and the limiting block is stabilized within the sliding opening by the reset mechanism when no external force is applied, the force-bearing block is located above the limiting block, and an inclined block is fixed on one outer wall of the limiting block.
[0004] Based on the above search and combined with existing technology, it was found that the existing cofferdam structure uses a complex mechanical structure to make a knocking sound to remind construction workers when the piles are in place. However, since large-scale machinery is often used for hoisting, sinking and driving piles during construction, the noise on site is relatively high. Even with sound prompts, the workers may still ignore the prompts due to the noise, and the actual effect is not ideal. Utility Model Content
[0005] The purpose of this utility model is to provide a cofferdam structure for water conservancy engineering construction, so as to solve the problems mentioned in the background art.
[0006] The technical solution of this utility model is: a cofferdam structure for water conservancy engineering construction, comprising:
[0007] Piles are driven into the ground, and multiple piles are connected in a row to form a closed cofferdam.
[0008] A fixed top column is fixed to the upper end of one side wall of the pile.
[0009] The mounting block is fixed to the upper end of the side wall of the pile away from the fixed top column. One side of the mounting block extends away from the fixed top column. The mounting block has a mounting hole on the side outside the upper end face of the pile for the fixed top column to be inserted.
[0010] The lifting tank is slidably connected to the mounting hole via a sliding structure. The lifting tank is filled with a colored gas whose color is distinctly different from the surrounding environment and the color of the stake.
[0011] The upper part of the periphery of the lifting bucket is provided with a smoke outlet. When the lifting bucket is located in the mounting hole, the smoke outlet is blocked by the inner wall of the mounting hole.
[0012] When the top heights of two adjacent piles are the same, the fixed top column is movably inserted into the mounting hole and lifts the lifting bucket, so that the smoke outlet is exposed above the mounting block, and the colored gas in the lifting bucket emerges from the smoke outlet to form a colored smoke column.
[0013] Preferably, the sliding structure includes:
[0014] A sliding groove is formed on the inner sidewall of the mounting hole, and the sliding groove extends vertically and communicates with the mounting hole.
[0015] The slider is fixed to the outer wall of the lifting bucket and is slidably connected in the groove.
[0016] Preferably, a compression spring is also provided in the mounting hole, with the upper end of the compression spring fixed to the top wall of the slide groove and the lower end of the compression spring fixed to the upper end of the slider.
[0017] Preferably, the mounting block is further provided with a smoke inlet hole on the side away from the fixed top column, and the smoke inlet hole extends laterally and communicates with the mounting hole;
[0018] The lifting bucket is also provided with a smoke inlet hole, which is connected to the smoke filling hole;
[0019] The sealing plug inside the smoke filling hole is equipped with a sealing plug.
[0020] Preferably, the plug of the sealing plug is disposed inside the smoke inlet hole, and the tail end of the sealing plug has a plug cap with a diameter larger than the inner diameter of the smoke inlet hole, and a groove is formed on the periphery of the plug cap of the sealing plug.
[0021] Preferably, the diameter of the fixed top column is smaller than the inner diameter of the mounting hole, and the lower end of the fixed top column is integrally formed with a fixing plate whose diameter is smaller than the inner diameter of the mounting hole and larger than the diameter of the fixed top column. The fixing plate is fixed to the upper end face of the insertion pile by bolts.
[0022] The mounting block has a connection hole, and a bolt for fixing the mounting block and the stake passes through the connection hole.
[0023] This utility model provides an improved cofferdam structure for hydraulic engineering construction, which has the following improvements and advantages compared with the prior art:
[0024] This invention, through the arrangement of a fixed top column, mounting block, and lifting bucket, allows the fixed top column to be movably inserted into the mounting hole when two adjacent piles are at the same height, lifting the lifting bucket and exposing the smoke outlet above the mounting block. This causes colored gas from the lifting bucket to emerge from the smoke outlet, forming a colored smoke column. The colored smoke column, clearly distinguishable from the surrounding environment and the pile color, provides a direct and obvious signal, reminding workers that the pile has been installed correctly. Compared to using knocking sounds, using colored gas is more intuitive and less affected by the environment or noise at the construction site, making it less likely for workers to overlook the reminder, thus achieving a better alerting effect.

[0032] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0033] This utility model provides an improved cofferdam structure for water conservancy engineering construction. The technical solution of this utility model is as follows:
[0034] like Figures 1-4 As shown, a cofferdam structure for hydraulic engineering construction includes:
[0035] Piles 1, and self-sealing structures (not shown in the figure) are provided on both sides of multiple piles 1. The self-sealing structure adopts the self-sealing structure commonly used in the prior art and applicable to this embodiment, which enables two adjacent piles 1 to be in a sealed state after installation, and multiple piles 1 are connected in a row to form a sealed dam.
[0036] Fixed top column 2, fixed top column 2 is fixed to the upper end of one side wall of pile 1;
[0037] Mounting block 3 is fixed to the upper end of the side wall of the stake 1 away from the fixed top column 2. One side of mounting block 3 extends away from the fixed top column 2. Mounting block 3 has a mounting hole 302 on the side of the upper end face of the stake 1 for the fixed top column 2 to be inserted. From the above connection relationship, it can be seen that, combined with the attached... Figure 1 and attached Figure 2 During the insertion of the first pile 1, the protruding end of the mounting block 3 abuts against the top of the previous pile 1, so that the two piles 1 are at the same horizontal level. That is, when the current pile 1 is inserted downward, the mounting block 3 on the current pile 1 overlaps the top of the previous adjacent pile 1, thereby achieving the purpose of making the two adjacent piles 1 at the same horizontal level. At the same time, the insertion and cooperation between the fixed top column 2 and the mounting hole 302 can ensure that the posture of the two adjacent piles is consistent when the insertion is about to be completed, thereby achieving the positioning and installation effect, making the installation angle and installation posture of the two adjacent piles consistent, and making the cofferdam more compact.
[0038] The diameter of the fixed top column 2 is smaller than the inner diameter of the mounting hole 302 so that the fixed top column 2 can be inserted into the mounting hole 302. The lower end of the fixed top column 2 is integrally formed with a fixing plate 201 with a diameter smaller than the inner diameter of the mounting hole 302 and larger than the diameter of the fixed top column 2. The fixing plate 201 is fixed to the upper end face of the insert 1 by bolts. The mounting block 3 is provided with a connecting hole 301. The bolts for fixing the mounting block 3 and the insert 1 are inserted through the connecting hole 301. The setting of the fixing plate 201 and the connecting hole 301 can facilitate the detachable fixing of the fixed top column 2 and the mounting block 3 to the insert 1, so that the fixed top column 2 and the mounting block 3 can be quickly installed before use, and when not in use, the fixed top column 2 and the mounting block 3 can be disassembled and stored.
[0039] The lifting tank 4 is slidably connected to the mounting hole 302 through a sliding structure. The lifting tank 4 is filled with a colored gas whose color is distinctly different from the surrounding environment and the color of the stake 1.
[0040] Among them, the upper part of the side of the lifting bucket 4 is provided with a smoke outlet 401. When the lifting bucket 4 is located in the mounting hole 302, the smoke outlet 401 is blocked by the inner wall of the mounting hole 302.
[0041] From the above connection relationship, it can be seen that, combined with the appendix Figure 1 -Attached Figure 3 When the top heights of two adjacent stakes 1 are the same, the fixed top column 2 is movably inserted into the installation hole 302 and lifts the lifting bucket 4, so that the smoke outlet 401 is exposed above the installation block 3. Finally, the colored gas in the lifting bucket 4 emerges from the smoke outlet 401 to form a colored smoke column. The colored smoke column, which is clearly different in color from the surrounding environment and the color of the stake 1, can form a clear and intuitive signal to remind the staff that the stake 1 has been installed in place. Compared with the reminder by knocking, the reminder by colored gas is more intuitive and less affected by the environment and noise of the construction site. The staff is less likely to ignore the reminder, thus achieving a better reminder effect.
[0042] Furthermore, the sliding structure includes:
[0043] The slide 303 is formed on the inner wall of the mounting hole 302, and the slide 303 extends vertically and communicates with the mounting hole 302.
[0044] Slider 5 is fixed to the outer wall of the lifting bucket 4, and slides within the groove 303. From the above connection relationship, it can be seen that, combined with the attached... Figure 2 and attached Figure 3 The lifting bucket 4 is slidably connected to the slide groove 303 by the slider 5, so that when the lifting bucket 4 is lifted by the fixed top column 2, it can slide vertically along the slide groove 303 (mounting hole 302), thereby driving the lifting bucket 4 to rise and expose the smoke hole 401, so as to form a colored smoke column to give workers a clear warning.
[0045] Furthermore, a compression spring 6 is also provided inside the mounting hole 302. The upper end of the compression spring 6 is fixed to the top wall inside the slide groove 303, and the lower end of the compression spring 6 is fixed to the upper end of the slider 5. From the above connection relationship, it can be seen that, combined with the attached... Figure 2 and attached Figure 3 The compression spring 6 uses its own elastic force to push the slider 5 against the lower end of the slide groove 303, so that the lifting bucket 4 always remains at the lower end of the mounting hole 302 when it is not lifted by the fixed top column 2. This can prevent the lifting bucket 4 from rising due to vibration during transportation or installation, which would cause the smoke outlet 401 to be exposed prematurely and cause an incorrect warning signal.
[0046] Furthermore, a smoke inlet 304 is provided on the side of the mounting block 3 away from the fixed top column 2. The smoke inlet 304 extends laterally and communicates with the mounting hole 302.
[0047] The lifting bucket 4 is also provided with a smoke inlet 402, which is connected to the smoke filling hole 304;
[0048] Among them, the inner sealing plug of the smoke filling hole 304 is equipped with a sealing plug 7. As can be seen from the above connection relationship, combined with the attached Figure 2 and attached Figure 3 When not in use, colored gas can be filled into the lifting tank 4 through the smoke filling hole 304 and the smoke inlet hole 402, and the sealing plug 7 is used to form a sealed structure, so that the lifting tank 4 can be reused to play a reminder role. Reuse can reduce the cost of equipment use and reduce costs and increase efficiency.
[0049] The plug of the sealing plug 7 is disposed inside the smoke inlet hole 304. The tail end of the sealing plug 7 has a plug cap with a diameter larger than the inner diameter of the smoke inlet hole 304. A groove 701 is formed around the plug cap of the sealing plug 7. From the above connection relationship, it can be seen that, combined with the attached... Figure 2 and attached Figure 4 The groove 701 makes it easier for staff to pull out the sealing plug 7, thus making it easier to fill the lifting tank 4 with colored gas.
[0050] Specifically, the working principle is as follows: First, a large machine is used to insert the first stake 1. During the installation of the first stake 1, close attention needs to be paid to the installation angle, depth, and other information of the stake 1. After the first stake 1 is installed, the subsequent stakes 1 are inserted in sequence. During the insertion of the subsequent stakes 1, the installation angle only needs to be adjusted before inserting the stake 1 downwards. When the stake 1 is about to be inserted, one side of the mounting block 3 on the stake 1 extends and is movably fitted onto the fixed top column 2 of the previous stake 1 through the mounting hole 302, so that the lifting bucket 4 rises under the lifting action of the fixed top column 2. When the bottom of the mounting block 3 is flush with the previous stake 1, the bucket rises. When the upper surfaces of the two stakes 1 come into contact, the insertion operation is completed. At this time, the upper surfaces of the two stakes 1 remain horizontal, and the smoke outlet 401 at the top of the lifting bucket 4 is exposed above the mounting block 3. The colored gas inside the lifting bucket 4 emerges from the smoke outlet 401 and forms a colored smoke column. The colored smoke column, which is clearly different in color from the surrounding environment and the stake 1, can form a clear and intuitive signal to remind the staff that the stake 1 has been installed in place. Compared with using knocking sounds to remind, using colored gas to remind is more intuitive and less affected by the environment and noise of the construction site. The staff is less likely to ignore the reminder, thus achieving a better reminder effect.
