Description

Technical Field

[0001] The utility model relates to the technical field of embankment slope drainage, in particular to a wave-proof and drainage device for the embankment slope on the water side of a seawall. Background Art

[0002] After the sea waves pass over the seawall, they will scour the upper surface and side dikes of the seawall, which may easily cause damage to the upper surface and side dikes of the seawall, and form water accumulation on the upper surface and side dikes of the seawall. If the seawall is raised and widened, and designed to prevent waves from passing over the dike, the waves can be prevented from passing over the dike. However, since dike construction consumes too much manpower and material resources, the investment in the project will increase significantly. Moreover, since the waves pass over the dike, the water enters the protected objects behind the dike, affecting their normal life. In the prior art, wave-breaking boards and drainage ditches are often set on the side dikes to block and discharge the waves.

[0003] The wave-breaking board and drainage trough structure can not only reduce the erosion of seawalls by waves, but also collect the seawater that crosses the wave-breaking bank and discharge it back into the sea. However, the fixed wave-breaking board is set to block the waves. Over time, the fixed wave-breaking board will gradually be eroded by the waves, and the blocking effect of a single wave-breaking board on the waves is too simple. For this reason, we propose a wave-breaking and drainage device for the waterside slope of the seawall. Utility Model Content

[0004] In view of the inconvenience of using the wave-breaking and drainage devices on the waterside slope of the seawall in the prior art, the utility model provides a wave-breaking and drainage device on the waterside slope of the seawall, which has the advantage of guiding the flow of seawater to form convection and reduce scouring.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wave-breaking and drainage device for the water-side embankment slope of a seawall, comprising an embankment slope main body, the outside of which is sequentially provided with a protrusion structure and a groove structure, a diversion block is fixedly connected to the top of the groove structure, a scouring groove is provided inside the groove structure, a reflux groove is provided inside the scouring groove, a wave-breaking wall is fixedly connected to the top of the embankment slope main body, a reserved hole is provided at the front of the wave-breaking wall, and a connecting groove is provided inside the wave-breaking wall.

[0006] Preferably, the communicating groove is arranged obliquely with respect to the wave-breaking wall, and a drainage pipe is fixedly connected to the tail of the communicating groove, and the drainage pipe is connected to a reserved hole for drainage.

[0007] Preferably, the length of the diverter block is greater than the length of the scouring trough, and arc-shaped side walls are provided on both sides of the diverter block, and the arc-shaped side walls are used to reduce water resistance.

[0008] Preferably, a plurality of the protrusion structures and the groove structures are provided and evenly distributed, and the protrusion structures are fixedly connected to the groove structures.

[0009] Preferably, the bottom and top of the raised structure are both configured as arc-shaped bending structures, the bottom structure length of the raised structure is greater than the top structure length, and the inclination of the raised structure gradually increases from bottom to top to achieve the purpose of separating the ocean currents.

[0010] Preferably, the bottom and top of the groove structure are both arranged as arc-shaped bending structures, the top structure length of the groove structure is greater than the bottom structure length thereof, the bottom of the groove structure is narrow and the top is wide, so that the passing water flow can form a vortex after being diverted by the diversion block to offset the impact force.

[0011] Preferably, two reflow grooves are provided symmetrically with respect to the flushing groove, and the reflow groove is provided as an arc structure, so that the water flow entering the reflow groove can form convection with itself to reduce the impact force.

[0012] Beneficial effects:

[0013] 1. The wave-proof and drainage device on the waterside slope of the seawall guides the direction of the water flow when the seawater is scouring through the convex structure and the groove structure, so that the seawater generates convection and collision in the top area of ​​the groove structure, reducing the impact force of the sea current.

[0014] 2. The wave-proof and drainage device on the waterside slope of the seawall guides the flow of water entering the scouring groove through the reflow groove, so that the water entering the reflow groove can form convection with itself to reduce the impact force.

[0023] The length of the diverter block 4 is greater than the length of the scouring trough 5 , and arc-shaped side walls 11 are provided on both sides of the diverter block 4 , and the arc-shaped side walls 11 are used to reduce water resistance.

[0024] There are several protrusion structures 2 and groove structures 3 which are evenly distributed, and the protrusion structures 2 and groove structures 3 are fixedly connected.

[0025] Among them, the bottom and top of the raised structure 2 are both set as arc-shaped bending structures, the bottom structure length of the raised structure 2 is greater than its top structure length, and the inclination of the raised structure 2 gradually increases from bottom to top to achieve the purpose of separating the ocean currents.

[0026] Among them, the bottom and top of the groove structure 3 are both set as arc-shaped bending structures, the top structure length of the groove structure 3 is greater than the bottom structure length of itself, the bottom of the groove structure 3 is narrow and the top is wide, so that the passing water flow can form a vortex after being diverted by the diversion block 4 to offset the impact force.

[0027] Working principle: When the wave-breaking and drainage device on the waterside of the seawall is used, the convex structure 2 can cooperate with the groove structure 3 to guide the direction of the water flow when the seawater is scouring. The inclination of the convex structure 2 gradually increases from bottom to top, which can make the water flow that scours the surface of the convex structure 2 gradually separate and flow to both sides, so as to achieve the purpose of separating the sea current. The bottom of the groove structure 3 is narrow and the top is wide, so that the passing water can flow to the middle again after being diverted by the diversion block 4, and merge with the water flow diverted by the convex structure 2 to form convection to offset the impact force, so that the seawater generates convection and collides in the top area of ​​the groove structure 3, reducing the impact force of the sea current, and the water flow passing through the main body of the embankment slope 1 will preferentially enter the inside of the reserved hole 8, and flow to the drainage pipe 10 through the connecting groove 9 for discharge, thereby improving the wave-breaking and drainage effects of the device.

[0030] Working principle: When the wave-breaking and drainage device is used on the waterside slope of the seawall, the water flow entering the scouring groove 5 can be guided by the return groove 6 set as a semicircular structure, so that the water flow entering the return groove 6 can form convection with itself to reduce the impact force.
