Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction technology, specifically to a bag cofferdam device. Background Technology

[0002] In the field of water conservancy projects or comprehensive river regulation projects, structures often require dry-land construction. Under current technology, considering factors such as water depth, flow velocity, riverbed characteristics, and construction requirements, earth-rock cofferdams, sheet pile cofferdams, or concrete cofferdams are commonly used. Earth-rock cofferdams require large equipment for construction, and due to their weight and size, they are difficult to transport, resulting in high construction costs. Sheet pile cofferdams cannot be implemented on hard riverbeds with foundations such as concrete or rock, and the installation of sheet piles requires large equipment for extraction, making them unsuitable for shallow water levels to meet vessel draft requirements. Concrete cofferdams are typically used in deep-head longitudinal cofferdams, often combined with guide walls of permanent structures, resulting in extremely high construction and dismantling costs. In short, existing cofferdam systems are heavy, inconvenient to construct, and costly. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a lightweight, easy-to-construct, and low-cost bag cofferdam device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A bag-type cofferdam device includes a bag and two spaced-apart base frames. The tops of the two base frames are connected by an upper connecting rod and have inlets and outlets for the bag to enter and exit. The tops of the two base frames are connected by a lower connecting rod. A net is provided inside the base frames. An accommodating space is formed between the two base frames. The bag is accommodated in the accommodating space and is provided with filling and draining ports. Lifting lugs are provided on the base frames.

[0005] As a further improvement to the above technical solution: The basic frame is provided with inserts at both ends for securing it to the bottom of the river.

[0006] The insert is a steel nail.

[0007] The basic frame is square.

[0008] The top of the bag is suspended from the upper connecting rod by a rope.

[0009] The filling and draining ports are located at the top of the bladder.

[0010] The bottom of the two base frames are spaced apart to form an opening through which the bottom of the pouch passes.

[0011] An upper baffle is detachably connected between the two base frames, the upper baffle being positioned above the pouch.

[0012] The upper frame forms a support platform for holding the counterweight.

[0013] The upper support frame is fixedly connected to the base frame by connecting bolts.

[0014] Compared with the prior art, the advantages of this utility model are: This utility model discloses a bag cofferdam device. In use, the bag cofferdam device is installed around the construction site within the river channel, and the bag is filled with liquid, causing it to expand and press tightly between two foundation frames to form a retaining wall-like structure. This bag cofferdam device is hoisted and installed before the bag is filled with liquid, making it lightweight. Furthermore, the liquid is filled after installation, making construction more convenient and cost-effective compared to existing cofferdam devices. Moreover, when changing the construction location, the liquid in the bag can be drained and gas can be filled in, increasing the upward buoyancy of the bag cofferdam device and facilitating relocation.

[0023] Example 1: Figure 1 and Figure 2 This invention illustrates an embodiment of the bag-type cofferdam device. The bag-type cofferdam device of this embodiment includes a bag 1 and two spaced-apart base frames 2. The tops of the two base frames 2 are connected by an upper connecting rod 3 and have inlets and outlets 4 for the bag 1 to enter and exit. The tops of the two base frames 2 are connected by a lower connecting rod 41. A net body 5 is provided inside the base frame 2. An accommodating space 6 is formed between the two base frames 2. The bag 1 is accommodated in the accommodating space 6 and is provided with an inlet / outlet port 11. The base frame 2 is provided with a lifting lug 21.

[0024] In use, this bag cofferdam device is installed around the construction site within the river channel, and liquid is filled into the bag 1, causing it to expand and press tightly between two foundation frames 2 to form a retaining wall-like structure. This bag cofferdam device is hoisted and installed before the bag 1 is filled with liquid, making it lightweight. Furthermore, the liquid is filled after installation, making construction more convenient and cost-effective compared to existing cofferdam devices. When changing the construction location, the liquid in the bag 1 can be drained and gas can be filled in, increasing the upward buoyancy of the bag cofferdam device and facilitating relocation.

[0025] Furthermore, in this embodiment, the two ends of the base frame 2 are respectively provided with inserters 7 for securing it to the bottom of the river channel. The base frame 2 is secured to the bottom of the river channel by the inserters 7, thereby improving the overall water-blocking strength. Preferably, the inserters 7 are steel nails.

[0027] Furthermore, in this embodiment, the top of the bag 1 is suspended from the upper connecting rod 3 by a suspension rope 8. The filling and draining port 11 is located at the top of the bag 1. The top of the bag 1 is suspended from the upper connecting rod 3 by the suspension rope 8 to prevent the bag 1 from falling into the river water before being filled with liquid, and to ensure that the filling and draining port 11 at the top of the bag 1 is above the river water, which facilitates filling and draining.

[0028] Furthermore, in this embodiment, the bottoms of the two basic frames 2 are spaced apart with openings 22 for the bottom of the bag 1 to pass through. In this way, the bottom of the bag 1 can be pressed tightly against the bottom of the river channel, improving the water-blocking effect.

[0029] Example 2: Figure 3 Another embodiment of the bag-type cofferdam device of this utility model is shown. The structure of the bag-type cofferdam device in this embodiment is basically the same as that in Embodiment 1, except that an upper baffle 9 is detachably connected between the two basic frames 2, and the upper baffle 9 is positioned above the bag 1. The upper baffle 9 is positioned above the bag 1 to prevent the bag 1 from deforming excessively upward after being squeezed by river water, which is beneficial to maintaining the water-blocking effect of the bag 1.

[0030] Furthermore, in this embodiment, a support platform 92 for supporting the counterweight 91 is formed on the upper baffle 9. The counterweight 91 can be added to the support platform 92 to improve the overall stability and water-blocking strength.
