Description

Technical Field

[0001] The utility model relates to the technical field of flood control and slope protection, in particular to a flood control and slope protection for a water conservancy project. Background Art

[0002] The embankment and river slope protection in flood control projects is a large-scale and wide-ranging infrastructure. People are pursuing the harmonious coexistence of man and nature and have higher and higher requirements for ecological slope protection. Consider the ecological slope protection function as well as the engineering function and safety function, and select and establish an engineering slope protection method that takes into account flood control, ecology and conservation. The construction of ecological slope protection projects for flood control projects should establish the concept of "respecting nature and restoring nature" so that the slope protection project can be integrated with the surrounding environment.

[0003] The existing flood control slope protection is prone to landslides. The existing flood control slope structures are relatively simple, and the slope protection is prone to landslides. It is not convenient to drain water in time, and it is easy to get blocked during drainage, causing the drainage pipe to be unable to drain water, resulting in the loss of drainage function. For this reason, we propose a water conservancy project flood control slope protection. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a flood control slope protection for a water conservancy project, which can control the amount of flood discharge according to the water level, has a firm structure, and extends the service life, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flood control slope protection for a water conservancy project, comprising a gravel transition layer and a flood spillway;

[0006] Gravel transition layer: laid on the inclined surface of the slope, the upper surface of the gravel transition layer is provided with a concrete layer, the concrete layer is arranged in a stepped shape, and fixed piles are evenly arranged inside the slope, and the upper ends of the fixed piles all pass through the gravel transition layer and extend to the inside of the concrete layer;

[0007] Spillway: The array is set inside the slope. The spillways all pass through the gravel transition layer and extend to the top of the concrete layer. The amount of flood discharge can be controlled according to the water level, reducing the lateral pressure of the river water on the concrete layer. The structure is firm, avoiding landslides and extending the service life.

[0008] Furthermore, the spillway includes a diversion channel and a main channel. The diversion channels are evenly arranged at the upper end of the interior of the slope. The diversion channels pass through the gravel transition layer and extend to the top of the concrete layer. The main channel is evenly arranged at the lower end of the interior of the slope. The lower ends of the diversion channels are connected to the interior of the main channel. The left ends of the main channels extend to the left side of the slope, so that the channel water is automatically discharged when the water level is too high.

[0009] Furthermore, the diameter of the main channel is greater than the diameter of the branch channel, so that the branch channels connected to the same main channel can be used normally, ensuring the flood discharge capacity.

[0010] Furthermore, filter cartridges are provided on the upper surface of the concrete layer, and the filter cartridges correspond to the vertical positions of the water inlets of the diversion channels respectively, so as to filter impurities on the surface to prevent them from entering the diversion channels and clogging the diversion channels.

[0011] Furthermore, the top plate of the filter cylinder is threadedly connected to a screw, and the lower end of the screw is rotatably connected to a plug, which is respectively arranged in cooperation with the water inlet of the diversion channel. The top of the screw is provided with a handwheel to block the diversion channel, thereby facilitating the adjustment and control of the water level in the canal.

[0012] Furthermore, an arc-shaped pressure relief strip is provided between the right side surface and the adjacent upper surface of the concrete layer, and an avoidance hole corresponding to the filter cylinder is provided inside the arc-shaped pressure relief strip, which diverts the force of the water flow upward and reduces the lateral pressure of the river water on the concrete layer.

[0013] Furthermore, the fixing piles are reinforced concrete fixing piles to ensure the supporting strength of the fixing piles.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the flood control and slope protection of the water conservancy project has the following advantages:

[0015] During the flood season, the plugs are separated from the water inlets of the diversion channels. When the water level exceeds the water inlet of the diversion channels, the river water enters the main channel from the diversion channels and is discharged to the left side of the slope, which plays a role in flood discharge. The filter cartridge can block the garbage floating on the water surface to prevent the garbage from entering the diversion channels due to the gravity of the water flow and blocking the diversion channels. When the water level of the river channel needs to be raised, the screw can be rotated according to demand. The screw drives the plug to move downward relative to the filter cartridge, so that the plug blocks the water inlet of the diversion channel, so that more water is accumulated in the river channel when the rainy season comes. The arc-shaped pressure relief strip diverts the water flow upward. The flood control and slope protection of this water conservancy project can control the amount of flood discharge according to the water level and reduce the lateral pressure of the river water on the concrete layer. The structure is firm, landslides are avoided, and the service life is extended. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 , This embodiment provides a technical solution: a flood control slope protection for a water conservancy project, comprising a gravel transition layer 2 and a spillway 3;

[0022] Gravel transition layer 2: laid on the inclined surface of the slope 1, a concrete layer 4 is provided on the upper surface of the gravel transition layer 2, and the concrete layer 4 is arranged in a stepped manner. Fixed piles 9 are evenly arranged inside the slope 1, and the upper ends of the fixed piles 9 pass through the gravel transition layer 2 and extend to the inside of the concrete layer 4. The fixed piles 9 are reinforced concrete fixed piles to ensure the supporting strength of the fixed piles 9.

[0023] Flood spillway 3: The array is arranged inside the slope 1. The flood spillway 3 passes through the gravel transition layer 2 and extends to the top of the concrete layer 4. The flood spillway 3 includes a diversion channel 31 and a main channel 32. The diversion channels 31 are evenly arranged at the upper end of the interior of the slope 1. The diversion channels 31 pass through the gravel transition layer 2 and extend to the top of the concrete layer 4. The main channel 32 is evenly arranged at the lower end of the interior of the slope 1. The lower end of the diversion channel 31 is connected to the interior of the main channel 32. The left end of the main channel 32 extends to the left side of the slope 1. When the water level is too high, the canal water is automatically discharged. The diameter of the main channel 32 is larger than the diameter of the diversion channel 31, so that the diversion channels 31 connected to the same main channel 32 can be used normally to ensure the flood discharge capacity. The upper surface of the concrete layer 4 is provided with a filter cartridge 5, and the filter cartridge 5 is respectively connected to the diversion channel The vertical position of the water inlet of 31 corresponds to that of the filter cartridge 5. The filter cartridge 5 can block the garbage floating on the water surface to prevent the garbage from entering the inside of the diverter channel 31 due to the gravity of the water flow and blocking the diverter channel 31. The top plate of the filter cartridge 5 is threadedly connected with a screw 6, and the lower end of the screw 6 is rotatably connected with a plug 7. The plug 7 is respectively arranged in cooperation with the water inlet of the diverter channel 31, and the plug 7 is respectively in a separated state from the water inlet of the diverter channel 31. When the water level exceeds the water inlet of the diverter channel 31, the river water enters the main channel 32 from the diverter channel 31 and is discharged to the left side of the slope 1, which plays a role in flood discharge. A hand wheel is provided on the top of the screw 6 to block the diverter channel 31, which is convenient for adjusting and controlling the water level in the river channel. By rotating the screw 6, the screw 6 drives the plug 7 to move downward relative to the filter cartridge 5, so that the plug 7 blocks the water inlet of the diverter channel 31.

[0024] Among them: an arc-shaped pressure relief strip 8 is provided between the right side surface of the concrete layer 4 and the adjacent upper surface, and an avoidance hole corresponding to the filter cylinder 5 is provided inside the arc-shaped pressure relief strip 8. The arc-shaped pressure relief strip 8 diverts the force of the water flow upward, reducing the lateral pressure of the river water on the concrete layer 4.

[0025] The working principle of a water conservancy project flood control and slope protection provided by the utility model is as follows:

[0026] A hole is dug inside the slope 1, and a fixing pile 9 is placed inside the hole and fixed so that the upper end of the fixing pile 9 is exposed from the slope of the slope 1. A branch channel 31 and a main channel 32 are respectively provided inside the slope 1. The slope of the slope 1 is leveled, and then pebbles are laid so that half of the pebbles are embedded in the soil of the slope of the slope 1 and the other half is exposed from the slope 1. The slope of the slope 1 is compacted and concrete is poured on the slope of the slope 1 to form a concrete layer 4. The lower layer of the concrete layer 4, the pebbles and the upper layer of the slope of the slope 1 form a crushed stone transition layer 2. The crushed stone transition layer 2 can effectively increase the fixing effect of the concrete layer 4 and prevent the concrete layer 4 from sliding down along the slope of the slope 1 as a whole. The upper ends of the fixing piles 9 all pass through the crushed stone transition layer 2 and extend to the inside of the concrete layer 4, thereby improving the fixing effect of the concrete layer 4. The layer 4 is arranged in a stepped manner, and an arc-shaped pressure relief strip 8 is provided between the right side surface of the concrete layer 4 and the adjacent upper surface, which diverts the force of the water flow upward and reduces the lateral pressure of the river water on the concrete layer 4. During the flood season, the plug 7 is separated from the water inlet of the diversion channel 31. When the water level is above the water inlet of the diversion channel 31, the river water enters the main channel 32 from the diversion channel 31 and is discharged to the left side of the slope 1, which plays a role in flood discharge. The filter cartridge 5 can block the garbage floating on the water surface to prevent the garbage from entering the diversion channel 31 due to the gravity of the water flow and blocking the diversion channel 31. When the water level of the river channel needs to be raised, the screw 6 can be rotated according to demand, and the screw 6 drives the plug 7 to move downward relative to the filter cartridge 5, so that the plug 7 blocks the water inlet of the diversion channel 31, thereby accumulating more water in the river channel when the rainy season comes.
