Description

Technical Field

[0001] This utility model relates to the field of cofferdam structure technology, specifically to a prefabricated ditch and pond cofferdam device. Background Technology

[0002] In water conservancy infrastructure construction projects, the excavation of ditches and canals along ditches and ponds is a common operation. If the water flow cannot be effectively controlled during construction, it is easy for water from ditches and ponds to backflow into the canals. The water accumulation caused by this backflow will have many adverse effects on the construction, such as making the construction site muddy and increasing the difficulty and cost of construction.

[0003] Traditionally, the solution involves constructing cofferdams at the junction of ditches and canals to cut off water flow and prevent backflow. However, existing cofferdam devices and technologies have significant limitations. Most cofferdams use structures such as baffles and sandbags, which have poor sealing properties and are prone to overflow under localized water level changes such as water flow impacts during long-term use, resulting in muddy conditions behind the cofferdam. Therefore, a ditches and ponds cofferdam structure is needed that can isolate ditches and ponds from canals and prevent overflow under localized water level changes such as water flow impacts. In view of this, we propose a prefabricated ditches and ponds cofferdam device. Utility Model Content

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Please see Figure 1-4 The present invention will describe the above technical solution in detail through the following embodiments:

[0032] In this embodiment of the ditch and pond cofferdam device, all structural components are prefabricated for easy and rapid assembly, specifically including:

[0033] Cofferdam component 1, such as Figure 1 , Figure 3 The structure shown includes a water-blocking plate 101 installed at the connection between the channel and the ditch. The water-blocking plate 101 is used to prevent water from flowing through the channel into the construction area. To improve structural stability, side support plates 102 are installed on both sides of the water-blocking plate 101 to fit against the inner wall of the channel. To maintain the sealing performance with the inner wall of the channel, in this embodiment, a rubber sealing strip is adhered to the outer plate surface of the water-blocking plate 101 that fits against the inner wall of the channel to maintain the sealing effect between the water-blocking plate 101 and the channel. To improve structural stability, an arched top plate 103 is installed at the top of the side support plates 102 on both sides. A bracket 104 is installed on the inner side of the top plate 103, which can improve the overall structural stability of the cofferdam component 1.

[0034] It should be noted that when the cofferdam component 1 is used to block the flow of water, the surface water of the ditch or pond will impact the baffle plate 101, causing local water level changes and overflow. Therefore, in this embodiment, a water flow unit 3 is installed behind the baffle plate 101; Figures 2-4The structure shown includes a flow unit 3 comprising a flow guide chamber 31 and an overflow receiving chamber 32 connected to the side of the flow guide chamber 31 near the ditch. In this embodiment, to better contain the overflowing water and prevent the channel from becoming muddy, the overflow receiving chamber 32 is located at the upper end of the baffle plate 101, and the overflow receiving chamber 32 is provided with an overflow port 321. A drain port 311 is provided at the outlet end on the other side of the flow guide chamber 31. The overflow can flow into the flow guide chamber 31 from the overflow port 321 and finally be discharged through the drain port 311. In this embodiment, three valve pipes 6 are connected and installed at the drain port 311. Each valve pipe 6 is connected and installed with a flow guide pipe 4, and the end of the flow guide pipe 4 is placed in the water collection tank 5. When the water collection tank 5 is full, a single valve pipe 6 can be closed, the water collection tank 5 can be emptied, and the valve pipe 6 can be reset and opened. This design is highly practical and can effectively avoid overflow problems caused during the emptying of the water collection tank 5.

[0035] It is worth noting that in this embodiment, a filter screen 2 is detachably installed at the overflow port 321, and the flow guide chamber 31 adopts the following... Figure 4 The U-shaped structure with the opening facing upwards is shown; the filter plate 2 can filter larger impurities in the water, such as floating leaves, plastic bottles and other fixed impurities. In order to ensure flow, smaller impurities will still flow into the guide chamber 31. Therefore, the design of the U-shaped structure can buffer the water flow, avoid large impact forces, and allow the overflow water to slowly flow into the water collection tank 5, which is beneficial to protecting the structure of the water collection tank 5.

[0036] The working principle of the prefabricated ditch and pond cofferdam device in this embodiment is as follows: the ditch and pond cofferdam device is constructed as follows: Figure 1 and Figure 2 As shown in the diagram, this structure is installed at the junction of channels and ditches to isolate water flow. When the water fluctuates and causes overflow due to impact, the water will flow through the water flow unit 3, valve pipe 6, and guide pipe 4 into the collection tank 5. This prevents the construction area within the channel from becoming muddy. Furthermore, the various components of this structure are easy to assemble and disassemble, and it can be quickly installed on the construction site using a prefabricated assembly structure. There is no need to use a water pump to remove the overflow water, resulting in low operating costs and practicality.

[0037] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0038] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
