Description

Technical Field

[0001] The invention belongs to the technical field of debris flow protection engineering, and in particular relates to a debris flow retaining dam device for water conservancy construction. Background Art

[0002] A debris flow is a special type of flood caused by precipitation in valleys or hillsides, carrying a large amount of solid materials such as mud, sand, stones and boulders.

[0003] At present, debris flow dams block large rocks on the side facing the debris flow. After a long period of accumulation, the rocks will block the drainage holes on the debris flow dam, causing the water level to rise continuously, resulting in the failure of the debris flow dam function. In addition, the accumulated rocks are difficult to clean, affecting the secondary use of the debris flow dam. Summary of the Invention

[0026] 1. In the present invention, the debris flow mixed with stones impacts the arc-shaped guide member along the groove of the mountain base. Under the guiding action of the arc surface of the arc-shaped guide member, the fluid is thrown upward as a whole and impacts the impact filter. The filtered fluid flows into the dam body through the filter holes and is spread flat, and is buffered on the diversion cover. Part of the fluid enters the separation channel together with the stones from the falling channel. The stones fall into the stone accumulation layer through the action of the separation guide roller, and the fluid falls into the diversion channel, thereby achieving effective separation of the stones, avoiding huge damage to the place impacted by the downstream debris flow, and the stones will not accumulate in the upstream position. The stones accumulated on the stone accumulation layer are easy to clean, ensuring that the dam can be used stably for a long time.

[0027] 2. In the present invention, after the stones are separated, they fall from the second outlet onto the stone accumulation layer for distribution and accumulation, and the separated fluid flows from the first outlet into the diversion channel, thereby achieving effective separation of the stones and avoiding causing huge damage to the areas impacted by the downstream debris flow.

[0028] 3. In the present invention, the baffle has a flow-blocking effect on the fluid filtered out from the filter hole, thereby alleviating the impact force of the fluid. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] See also Figure 1-7The present invention provides a technical solution: a debris flow dam device for water conservancy construction, comprising:

[0040] The dam body 1 is fixed to the mountain base 2 by an anchoring structure. A descending channel 3 is provided at the top of the dam body 1. A separation channel 4 is provided inside the dam body 1. One end of the separation channel 4 extends to the front end of the dam body 1, and the other end of the separation channel 4 is connected to the descending channel 3.

[0041] An arc-shaped flow guide 5, which is fixed on the mountain base 2 through an anchoring structure, and the arc-shaped flow guide 5 is connected to the rear end of the dam body 1;

[0042] An impact filter 6 is fixed to the mountain base 2 via an anchoring structure, and the impact filter 6 is connected to the top of the dam body 1. The impact filter 6 is provided with a plurality of filter holes 7 extending forward and backward, and a V-shaped guide groove 8;

[0043] Multiple sets of separation guide rollers 9, which are arranged in a straight line and hinged in the separation channel 4;

[0044] A diversion channel 10, which is connected to the mountain base 2 and communicates with the separation channel 4;

[0045] a stone accumulation layer 11, which is connected to the mountain base 2 and covers the diversion channel 10;

[0046] a diversion cover 12 connected to the mountain base 2 and covering the stone accumulation layer 11 and the diversion channel 10, wherein the top surface of the diversion cover 12 is not higher than the top surface of the dam body 1;

[0047] A plurality of buffer pads 13 are provided at the bottom of the falling channel 3, and a buffer plate 14 is connected to the plurality of buffer pads 13 to buffer the falling stones;

[0048] The front end of the dam body 1 is provided with a first outlet 15 and a second outlet 16. The first outlet 15 and the second outlet 16 are respectively located below and above the nearest separation guide roller 9. The diversion channel 10 is connected to the first outlet 15, and the second outlet 16 is located above the stone accumulation layer 11, so that after the stones are separated, they fall from the second outlet 16 into the stone accumulation layer 11 for distribution and accumulation. The separated fluid flows from the first outlet 15 into the diversion channel 10, thereby achieving effective separation of the stones and avoiding causing huge damage to the areas impacted by the downstream debris flow.

[0049] A discharge port 17 is provided on the side wall of the falling channel 3. The discharge port 17 is located obliquely above the separation guide roller 9 to ensure that the mixed fluid of stones and mud can be effectively separated on the multiple separation guide rollers 9.

[0050] The top surface of the diversion cover 12 is provided with a plurality of baffles 18, which have a flow-blocking effect on the fluid filtered out from the filter hole 7 and alleviate the impact force of the fluid;

[0051] The bottom surface of the mountain base 2 is provided with a sinking trough 19, and the dam body 1 is installed in the sinking trough 19, so that the debris flow can smoothly enter the top of the dam body 1 for subsequent filtration and separation;

[0052] The dam body 1 is formed by connecting a plurality of steel plates, so that the device structure is diverse and can be used for long-term protection and temporary protection.

[0053] Working principle: First, the debris flow mixed with stones impacts the arc guide 5 along the groove of the mountain base 2. Under the guiding effect of the arc surface of the arc guide 5, the fluid is thrown upward as a whole and hits the impact filter 6. The filtered fluid flows into the dam body 1 through the filter hole 7 and is spread flat. It is buffered on the diversion cover 12. That is, the baffle 18 has a flow-blocking effect on the fluid filtered out of the filter hole 7, which relieves the impact force of the fluid. Secondly, under the guiding effect of the V-shaped guide groove 8, part of the fluid enters the falling channel 3 together with the stones. In the separation channel 4, during the process, the buffer plate 14 is connected to multiple buffer pads 13, which has a buffering effect on the falling stones. The stones fall from the discharge port 17 onto the separation guide roller 9. The stones fall onto the stone accumulation layer 11 through the action of the separation guide roller 9, and the fluid falls into the diversion channel 10, realizing the effective separation of the stones and avoiding huge damage to the areas impacted by the downstream debris flow. Finally, the stones will not accumulate in the upstream position, and the stones accumulated on the stone accumulation layer 11 are easy to clean, ensuring that the dam can be used stably for a long time.
