Technical Field

[0001] The utility model relates to the technical field of dam construction, in particular to a dam diversion tunnel plugging and anti-seepage structure. Background Art

[0002] The dam diversion tunnel plug is a vital water conservancy facility. It is located at the end of the dam diversion tunnel and plays a vital role. Its main function is to prevent water from leaking through the tunnel, thereby ensuring the safe and stable operation of the entire dam. The design and construction of this plug must strictly follow engineering standards to cope with various complex hydrogeological conditions and ensure that it can maintain structural integrity and sealing even under extreme conditions. Through the effective operation of this plug, the main structure of the dam can be effectively protected from water erosion, the service life of the dam can be extended, and to a certain extent, the economic benefits and safety of the entire water conservancy project can be improved.

[0003] During the actual use of the dam diversion tunnel, due to the influence of severe weather such as floods, the water level rises and the tunnel is submerged by accumulated water, causing the dam to lose its function and be damaged. The tunnel entrance is usually too large to be sealed with sandbags and other flood control equipment, making it impossible to seal the dam diversion tunnel after it is put into use, or the sealing time is long, and there is a defect that gaps are easily formed in the sealing. Utility Model Content

[0010] Preferably, the diameter of the injection hole is sixty millimeters.

[0011] Preferably, a plurality of through holes are provided on the surface of the embedded block.

[0012] The technical effects and advantages of this utility model are:

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0020] Reference Figure 1 - Figure 4As shown, the utility model provides a technical solution: a dam diversion tunnel plug and anti-seepage structure, including a plugging plate 1, a pre-embedded block 2 is fixedly connected to the bottom of the plugging plate 1, a pouring hole 3 is opened on the top of the plugging plate 1, a plurality of steel bars 4 are fixedly connected to one side of the plugging plate 1, and the other end of the steel bar 4 is fixedly connected to a baffle 5, and a sealing belt 6 is fixedly connected to the outside of the baffle 5. By placing the plugging plate 1 at the tunnel entrance, the baffle 5 is placed in the hole, so that the outside of the sealing belt 6 is tightly against the inner wall of the tunnel, the gap of the baffle 5 in the tunnel is reduced to prevent rainwater from seeping in, and then the plugging plate 1 is pushed inward to be close to the inner wall of the tunnel outlet, the pre-embedded block 2 is embedded in the tunnel ground to seal the bottom of the tunnel, and then concrete is poured into the interlayer between the plugging plate 1 and the baffle 5 through the pouring hole 3, so that the concrete fills the gap between the plugging plate 1 and the baffle 5 in the tunnel, and the solidified concrete is supported and reinforced by the provided steel bars 4, thereby achieving the effect of sealing and anti-seepage of the tunnel entrance.

[0021] Reference Figure 1 As shown, in this embodiment: a slope 7 is provided on one side of the plugging plate 1. Through the provided slope 7, the entrance of the tunnel can be closely attached to the slope 7, thereby reducing the gap between the plugging plate 1 and the tunnel entrance, improving the adaptability of the plugging plate 1 to the size of the entrance, and increasing the sealing performance of the plugging plate 1 to the entrance.

[0022] Reference Figure 2 As shown, in this embodiment: a pipe 8 is installed at the bottom of the baffle 5, one end of the pipe 8 passes through the bottom of the blocking plate 1, and a valve 9 is installed at one end of the pipe 8. The sewage on one side of the baffle 5 can pass through the arranged pipe 8 and valve 9. The valve 9 is opened and closed to allow the sewage to be discharged to the outside through the pipe 8, thereby reducing the impact force of the accumulated water on the baffle 5, preventing sewage from accumulating on one side of the baffle 5 for a long time, causing corrosion to the baffle 5 and the sealing belt 6, or preventing the risk of accumulated water seepage caused by long-term accumulation of sewage on one side of the baffle 5, or long-term accumulation of water.

[0023] Reference Figure 1 - Figure 4 As shown, in this embodiment: both ends of one side of the blocking plate 1 are fixedly connected with a slot block 10, the inner wall of the slot block 10 is inserted with a support rod 11, and the bottom of the support rod 11 is fixedly connected with a plurality of gaskets 12. By burying the support rod 11 in the foundation, the support rod 11 is inserted into the slot block 10, so that the support rod 11 supports one side of the blocking plate 1. Through the inclined placement of the support rod 11, when the blocking plate 1 is moved by force, it is supported by the support rod 11 and the gasket 12, thereby stabilizing the position of the blocking plate 1 and effectively preventing the blocking plate 1 from moving due to the impact force of the water flow.

[0024] Reference Figure 1As shown, in this embodiment: a plurality of triangular protrusions 13 are fixedly connected to one side of the baffle 5. When the baffle 5 is impacted by water flow, the design of the triangular protrusions 13 makes the surface of the baffle 5 uneven, thereby absorbing the impact force generated by the impact of the water flow and reducing the damage caused by the impact of the water flow on the baffle 5.

[0025] Reference Figure 1 - Figure 4 As shown, in this embodiment: the diameter of the pouring hole 3 is sixty millimeters. Through the setting of the pouring hole 3, most of the concrete vibrating rods used in the construction site can be inserted into the pouring hole 3 to one side of the blocking plate 1, vibrating the cement poured into the interlayer between the blocking plate 1 and the baffle 5, reducing the gaps in the cement, allowing the cement to flow evenly, and seepage filling the gaps to improve the sealing performance of the device.

[0026] Reference Figure 2 and Figure 3 As shown, in this embodiment: a plurality of through holes 14 are opened on the surface of the embedded block 2. Through the set through holes 14, when the embedded block 2 is embedded in the ground, the gaps in the through holes 14 can be filled with soil and concrete, thereby increasing the contact area between the embedded block 2 and the ground and improving the stability of the embedded block 2 in the ground.

[0027] Working principle: By placing the plugging plate 1 at the tunnel entrance, placing the baffle 5 in the tunnel, making the outer side of the sealing belt 6 close to the inner wall of the tunnel, reducing the gap of the baffle 5 in the tunnel to prevent rainwater seepage, and then pushing the plugging plate 1 inward to close to the inner wall of the tunnel outlet, embedding the embedded block 2 into the tunnel ground to seal the bottom of the tunnel, and then pouring concrete into the interlayer between the plugging plate 1 and the baffle 5 through the pouring hole 3, so that the concrete fills the gap between the plugging plate 1 and the baffle 5 in the tunnel, and the solidified concrete is supported and reinforced by the provided steel bars 4, thereby achieving the purpose of sealing the tunnel. The tunnel opening is sealed and anti-seepage effect. The inclined surface 7 is opened so that the tunnel opening can be tightly attached to the inclined surface 7, reducing the gap between the plugging plate 1 and the tunnel opening, improving the adaptability of the plugging plate 1 to the size of the opening, and increasing the sealing performance of the plugging plate 1 to the opening. The sewage on one side of the baffle 5 can pass through the provided pipe 8 and valve 9. The valve 9 is opened and closed to allow the sewage to be discharged to the outside through the pipe 8, reducing the impact of the accumulated water on the baffle 5, and preventing sewage from accumulating on one side of the baffle 5 for a long time, causing corrosion to the baffle 5 and the sealing belt 6, or long-term accumulation of water, causing water seepage. The risk of water flow is eliminated by burying the support rod 11 in the foundation so that the support rod 11 is inserted into the card slot block 10, so that the support rod 11 supports one side of the blocking plate 1. The support rod 11 is placed obliquely so that the blocking plate 1 is supported by the support rod 11 and the gasket 12 when it moves under force, thereby stabilizing the position of the blocking plate 1 and effectively preventing the blocking plate 1 from moving under the impact of water flow. When the baffle 5 is impacted by water flow, the design of the triangular protrusion block 13 makes the surface of the baffle 5 uneven, thereby absorbing the impact force generated by the impact of water flow and reducing the impact of water flow on the baffle. The damage caused by the impact of the plate 5 can be eliminated by setting the pouring hole 3, so that most of the concrete vibrating rods used in the construction site can be inserted into the pouring hole 3 to one side of the blocking plate 1, vibrating the cement poured in the interlayer between the blocking plate 1 and the baffle 5, reducing the gaps in the cement, making the cement flow evenly, and filling the gaps to improve the sealing of the device. Through the set through hole 14, when the embedded block 2 is embedded in the ground, the gap of the through hole 14 can be filled with soil and concrete, increasing the contact area between the embedded block 2 and the ground, and improving the stability of the embedded block 2 in the ground.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
