Description

Technical Field

[0001] The present application relates to an anti-impact dam protection structure. Background Art

[0002] As an important barrier to protect the safety of rivers or reservoirs, dams need to ensure the stability of dams as much as possible to prevent water from eroding the river channel. Currently, most of them are filled with stones and rocks, and they are generally passive, that is, they prevent erosion by enriching the river channel foundation. In fact, dam erosion includes two aspects of erosion. On the one hand, it is erosion along the direction of water flow, and on the other hand, it is erosion in the direction perpendicular to the water flow caused by the airflow and wind direction of the river. For erosion along the direction of water flow, the only way is to strengthen the anti-erosion ability of the structure. For erosion in the direction perpendicular to the water flow, in addition to the ability to resist erosion itself, it is also necessary to be destructive to its impact to avoid excessive extension and impact in the height direction. Utility Model Content

The present application arranges spaced blocking plates on the anti-impact bottom plate, and sets the highest point and the lowest point on the blocking plate, and respectively sets the upper circulation channel and the lower circulation channel, thereby ensuring the overall destructive capacity in the vertical water flow direction and minimizing the extended impact in the height direction as much as possible.

[0004] Preferably, a plurality of buffer holes are provided between adjacent blocking plates.

The present application further enhances the effect of destroying the impact of water flow in the height direction by arranging the anti-impact column in the buffer hole, so that the upper flow channel and the lower flow channel can be better utilized to reversely guide the water flow into the river channel.

[0006] Preferably, a clamping plate is provided at the bottom of the vertical column, and the clamping plate is provided below the impact-resistant bottom plate.

[0007] Preferably, the vertical column is a rectangular parallelepiped column, and a convex head is respectively arranged on each vertical surface of the vertical column, and the height of the arranged convex head gradually increases in the direction away from the river channel.

[0009] Preferably, the impact-resistant bottom plate is formed by splicing base blocks, and the upper and lower sides of the base blocks are respectively provided with arc-shaped plates with openings facing outward, and the left and right sides of the base blocks are respectively provided with rectangular grooves. The present application obtains the impact-resistant bottom plate by splicing base blocks, and then the rectangular grooves form buffer holes and the arc-shaped plates form blocking plates, thereby ensuring the assemblability of the overall structure.

[0010] Preferably, the left and right base blocks are arranged in parallel so that the rectangular grooves are spliced ​​to form buffer holes; the upper and lower base blocks are staggered so that the lower arc plate of the upper layer spans the arc plates on two adjacent base blocks of the lower layer.

[0020] In order to clearly illustrate the technical features of the present solution, the present application is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0021] In the first embodiment, if Figure 1 As shown, an impact-resistant dam protection structure includes an impact-resistant base plate 1, on which a plurality of spaced-apart blocking plates 2 are arranged, the blocking plates 2 are reciprocatingly bent along the length direction of the impact-resistant base plate 1 to form a cyclically arranged highest point 3 and lowest point 4, an upper circulation channel 5 is arranged at the highest point 3, and a lower circulation channel 6 is arranged at the lowest point 4.

[0022] When in use, the device is applied to be installed on the dam. If the water in the river or reservoir fluctuates in the height direction, due to the provision of a baffle plate 2 with a highest point 3 and a lowest point 4 provided on the baffle plate 2, the baffle plate 2 generates a reverse flow of water, which is retained through the upper flow channel 5 and the lower flow channel 6, thereby reducing the extension impact in the height direction.

[0023] In the second embodiment, if Figure 1-4 As shown, an impact-proof dam protection structure includes an impact-proof bottom plate 1, on which a plurality of spaced blocking plates 2 are arranged, and the blocking plates 2 are bent back and forth along the length direction of the impact-proof bottom plate 1 to form a cyclically arranged highest point 3 and lowest point 4, and an upper circulation channel 5 is arranged at the highest point 3, and a lower circulation channel 6 is arranged at the lowest point 4. A plurality of buffer holes 7 are also arranged between adjacent blocking plates 2. An auxiliary impact-proof column 8 is arranged in the buffer hole 7; the auxiliary impact-proof column 8 includes a vertical column 9 inserted into the buffer hole 7, and a plurality of protrusions 10 are arranged on the upper part of the vertical column 9; the protrusions 10 are in the shape of a frustum. A clamping plate 11 is arranged at the bottom of the vertical column 9, and the clamping plate 11 is arranged below the impact-proof bottom plate 1. The vertical column 9 is a rectangular parallelepiped column, and protrusions 10 are respectively arranged on each vertical surface of the vertical column 9, and the height of the arranged protrusions 10 gradually increases in the direction away from the river channel. A top frustum 12 is also provided on the top of the vertical column 9. The impact-resistant bottom plate 1 is formed by splicing base blocks 13, and arc-shaped plates 14 with outward openings are respectively provided on the upper and lower sides of the base block 13, and rectangular grooves 15 are respectively provided on the left and right sides of the base block 13. The base blocks 13 arranged on the left and right are arranged in parallel so that the rectangular grooves 15 are spliced ​​to form the buffer hole 7; the base blocks 13 arranged on the top and bottom are staggered so that the arc-shaped plates 14 at the bottom of the upper layer span the arc-shaped plates 14 on the two adjacent base blocks 13 of the lower layer.

[0024] During assembly, on the basis of the dam, an impact-resistant bottom plate 1 is obtained by splicing the base block 13, and then the rectangular groove 15 forms the buffer hole 7 and the arc plate 14 forms the blocking plate 2; when in use, the application is set on the dam. If the water in the river or reservoir fluctuates in the height direction, due to the setting of the blocking plate 2, and the highest point 3 and the lowest point 4 are set on the blocking plate 2, after the blocking plate 2 generates a reverse flow of water, it is retained through the upper flow channel 5 and the lower flow channel 6, thereby reducing the extension impact caused in the height direction.
