Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a seepage drainage structure for dam bodies. Background Technology
[0002] Seepage is a phenomenon that is difficult to avoid but cannot be ignored in the operation of hydraulic structures. When a serious seepage occurs in the dam body, corresponding treatment work is required. The principle of seepage treatment is "upstream blocking and downstream drainage". That is, first find the source of seepage upstream and try to block it to prevent water from entering the structure; downstream, take drainage measures to prevent seepage from carrying soil particles out, so as to avoid dam slope collapse and landslides.
[0003] Currently, when draining seepage water from the dam, filters are usually installed to prevent soil particles from being carried out. However, this can also cause soil particles to get stuck at the seepage outlet, affecting drainage efficiency and gradually worsening the drainage effect.
[0004] Therefore, this application provides a dam seepage drainage structure to solve the above-mentioned technical problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a dam seepage drainage structure to solve the problem in the prior art that when draining seepage water from the dam, in order to avoid soil particles being carried out, a filter screen is generally set up to intercept them. However, this will also cause soil particles to be blocked at the seepage outlet, affecting the drainage efficiency and the drainage effect of seepage water will gradually deteriorate.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] A dam seepage drainage structure includes a drainage cover, an opening on one side of the drainage cover and a first filter screen, a water guide pipe connected to the lower end of the drainage cover, a water collection cylinder in cooperation with the water guide pipe, and a drainage pipe installed at the bottom of the water collection cylinder.
[0008] The output end of the water guide pipe is connected to the middle of the water collecting cylinder. One end of the drain pipe extends into the top of the water collecting cylinder, and the other end is located outside the bottom of the water collecting cylinder, so that the drain cover, the water guide pipe, the water collecting cylinder and the drain pipe form a siphon structure.
[0009] Optionally, the drainage cover has two fixing ears symmetrically arranged on the side with the opening.
[0010] Optionally, the water guide pipe is installed on the bottom side of the drainage cover away from the opening.
[0011] Optionally, a second filter screen is laid on one end of the drain pipe that extends into the top of the water collection cylinder.
[0012] Optionally, a fixed flange is installed at one end of the drain pipe located outside the bottom of the water collection cylinder.
[0013] Optionally, a sealing seat is fixed in the middle of the drain pipe, and the sealing seat is threadedly fixed inside the bottom port of the water collection cylinder.
[0014] Optionally, a sealing ring is fixed around the upper end face of the sealing seat.
[0015] Compared with the prior art, this utility model has at least the following beneficial effects:
[0016] In the above solution, thanks to the siphon structure formed by the drainage cover, water guide pipe, water collection cylinder and drainage pipe, the drainage cover, water guide pipe and water collection cylinder can collect the seepage water in the dam body, and then form a siphon phenomenon when the water level reaches the top of the drainage pipe, and pump out the seepage water in the dam body through the drainage pipe, which can solve the problem of reduced drainage efficiency caused by the clogging of traditional filter screens to a certain extent.
[0017] In the above solution, thanks to the combination of the drain pipe, the second filter screen, and the sealing seat, the second filter screen can be used to further filter soil particles, and the drain pipe can be easily disassembled and maintained through the sealing seat.
[0018] In summary, this device can improve the efficiency of seepage drainage from the dam body through the siphon structure, and it is easy to disassemble and maintain, resulting in good performance. Attached Figure Description

However, this is only for illustrative purposes and is not intended to limit this utility model to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation
[0027] The following is a detailed description of a dam seepage drainage structure provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0028] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.
[0029] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.
[0030] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.
[0031] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.
[0032] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a dam seepage drainage structure, including a drainage cover 1. The drainage cover 1 has an opening on one side and is covered with a first filter screen 101. Two fixing ears 102 are symmetrically arranged on the side of the drainage cover 1 with the opening. The fixing ears 102 are provided with a plurality of mounting holes, which can be used with anchor bolts to fix them to the seepage position of the dam.
[0033] The lower end of the drainage cover 1 is connected to a water guide pipe 2, which is fitted with a water collecting cylinder 3. A drain pipe 4 is installed at the bottom of the water collecting cylinder 3. Specifically, the output end of the water guide pipe 2 is connected to the middle of the water collecting cylinder 3. One end of the drain pipe 4 extends into the top of the water collecting cylinder 3, and the other end is located outside the bottom of the water collecting cylinder 3, forming a siphon structure with the drainage cover 1, the water guide pipe 2, the water collecting cylinder 3, and the drain pipe 4. The water guide pipe 2 is installed on the bottom side of the drainage cover 1 away from the opening, and a second filter screen 401 is laid on the end of the drain pipe 4 that extends into the top of the water collecting cylinder 3. A fixing flange 402 is installed on the end of the drain pipe 4 located outside the bottom of the water collecting cylinder 3.
[0034] Cooperate Figure 4 As shown, a sealing seat 5 is fixed in the middle of the drain pipe 4. The sealing seat 5 is threadedly fixed inside the bottom port of the water collecting cylinder 3, forming a detachable installation. A sealing ring 501 is fixed around the upper end face of the sealing seat 5 to ensure the sealing effect after installation.
[0035] The working principle provided by this utility model is that, in use, the dam seepage drainage structure can collect the seepage water in the dam body through the drainage cover 1, and intercept the soil particles in the seepage water through the first filter screen 101 until the seepage water fills the inside of the drainage cover 1, the water guide pipe 2, and the water collection cylinder 3. Then the drainage pipe 4 will discharge the seepage water, forming a siphon phenomenon, and pumping out the seepage water in the dam body. This can solve the problem of reduced drainage efficiency caused by the clogging of traditional filter screens to a certain extent.
[0036] Meanwhile, due to the cooperation of the drain pipe 4, the second filter screen 401 and the sealing seat 5, the second filter screen 401 can be used to further filter soil particles, and the drain pipe 4 can be easily disassembled and maintained through the sealing seat 5.
[0037] In summary, this device can improve the efficiency of seepage drainage from the dam body through the siphon structure, and it is easy to disassemble and maintain, resulting in good performance.
[0038] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
