AI Technical Summary
In the case of high flow, the continuous impact force brought by the water flow can easily damage the arch formwork because the arch structure itself does not enhance the impact resistance.
An arched water conservancy corridor including the main body of the water conservancy corridor, the support mechanism and the pressure-dividing structure was designed. The pressure-dividing structure disperses the impact force of the water flow through components such as pressure-dividing plates, pressure-reducing blocks, sliding rods and springs, and enhances the impact resistance of the arch formwork through the reinforcement structure.
It effectively reduces the impact force of the arch formwork, extends the service life of the main body of the water conservancy corridor, and avoids damage caused by the increase in the impact force of the water flow.

[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water is a precious resource indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production. Water conservancy projects not only require the construction of dams, dikes, spillways and other facilities, but also the construction of arched water conservancy corridors. Corridors are specifically underground or ground waterways used to connect reservoirs and downstream water points. They are mainly used to transport water resources and are indispensable engineering buildings in water conservancy projects.

When the arched water conservancy corridor is transporting water resources, the arched template can continuously decompose the force exerted by the water flow. However, when the water resource transportation flow is too large, the water flow will bring continuous impact force. Since the impact resistance of the arched template itself is not increased due to the arched structure, the continuously increasing impact force can easily cause damage to the arched template.

[0033] Embodiment 3
[0034] See also Figure 1-6 On the basis of the above-mentioned embodiments, the support mechanism 2 of this embodiment includes a support block 201 fixed on the inner wall of the water conservancy corridor body 1, the outer wall of the support block 201 is threadedly connected to the inner wall of the water conservancy corridor body 1, and the support block 201 is provided with a plurality of groups, and every two groups of support blocks 201 are symmetrically distributed on the vertical central axis of the water conservancy corridor body 1, and each group of support blocks 201 is provided with a movable groove 202 inside, and the shape of the movable groove 202 is adapted to the shape of the two ends of the pressure dividing plate 301, and a spring 203 is connected to the top wall inside the movable groove 202, and both ends of the pressure dividing plate 301 extend to the inside of the movable groove 202, and the bottom end of the spring 203 extends to the top of the pressure dividing plate 301 and is welded to the top wall of the pressure dividing plate 301, and the support mechanism 2 is used to provide support for the two ends of the pressure dividing plate 301, and at the same time, under the telescopic function of the spring 203, the pressure dividing work of the pressure dividing plate 301 can be coordinated.
[0035] Working principle: First, when the water conservancy corridor body 1 is conveying water resources, when the water flow rate continues to increase, the water flow will exert an impact force on the arched structure inside the water conservancy corridor body 1. The impact force first contacts the bottom wall of the pressure dividing plate 301, and a small amount of water is discharged into the interior of the arched structure through the hydrophobic hole 5, so as to avoid excessive impact force on the pressure dividing plate 301;
[0036] Secondly, when the pressure dividing plate 301 is subjected to the impact force, it moves upward, and the two ends of the pressure dividing plate 301 slide on the inner side of the moving groove 202. When the pressure dividing plate 301 moves upward, it drives the bottom ends of the multiple groups of push rods 307 to move left or right. When the push rods 307 move, they push the decompression block 303 to move. The decompression block 303 slides on the outer side of the sliding rod 305, and at the same time, the spring 2 306 is squeezed to disperse the impact force on the pressure dividing plate 301.
