In the figure: 1. a dam body; 2. a communication section; 3. a storage section; 4. flood control baffles; 5. a vertical guide rail; 6. a water-facing surface; 7. a limit stop block; 8. the feet are enlarged.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The specific embodiments are only for explaining the present invention, and the present invention is not limited thereto, and those skilled in the art can make modifications without inventive contribution to the present embodiments as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
Example (b): the utility model provides a flood control dyke, as shown in figure 1, including dykes and dams body 1, dykes and dams body 1 adopts high strength waterproof concrete to pour, and upstream face 6 is the slope, and the top is the platform, and this internal intercommunication chamber that is provided with of dykes and dams, intercommunication chamber include at least:
one end of the communication section 2 is communicated with the storage section, and the other end of the communication section penetrates out of the upstream face of the dam body and is communicated with an external flood area;
a storage section 3, the top of which penetrates out of the top of the dam body and is communicated with the outside, and a flood control baffle 4 which rises along with the rise of the water level is arranged in the storage section;
the top of the dam body 1 is also provided with a vertical guide rail 5 for the flood control baffle to slide and guide.
Certainly in the actual production, flood control baffle 4 arranges in proper order along the length direction of dykes and dams body 1 and is provided with a lot of polylith, and vertical guide rail 5 also is provided with many in rows, and the intercommunication chamber also corresponds with flood control baffle and is provided with same quantity. Through the setting, the dykes and dams body can play basic flood control effect, reduces the water of normal water level to the erosion of side slope, and because the UNICOM section will store section and flood water UNICOM during the high water level to can let the flood control baffle upwards float in step, reach the effect that improves the flood bank temporarily, play good interim protection effect, also provide valuable time and space for fighting a rush to deal with an emergency for the flood resistance.
Specifically, flood control baffle with the open-top clearance fit who stores the section, the width of storing the section is greater than flood control baffle thickness, the open-top department that stores the section is provided with limit stop 7, flood control baffle's bottom be provided with limit stop butt complex enlargies foot 8.
The bottom surface of limit stop is decurrent inclined plane, and one side of enlarging the foot be with the ascending inclined plane of limit stop's bottom surface laminating, through enlarging foot and limit stop's butt cooperation, can prevent that flood control baffle from breaking away from dykes and dams open-top. In actual installation, the bottom amplification foot of the flood control baffle is connected in a split mode, and the amplification foot vertically penetrates through the top opening of the storage section and then is connected with the flood control baffle, for example, the flood control baffle is fixed in a welding mode.
Every flood control baffle sliding fit in a pair of in the vertical guide rail, just the flood control baffle deviates from vertical seal groove has been seted up to the one side of dykes and dams upstream face, every all be equipped with in the vertical guide rail with seal groove sliding plug complex sealing strip, work as when the flood control baffle is extruded to be lower than in the vertical guide rail, the sealing strip with seal groove sealing fit. Further, in order to improve the sealing performance, the sealing strip is a water-swelling strip.
And in order to strengthen the support intensity of vertical guide rail, still be provided with a plurality of installation departments on the one side that vertical guide rail deviates from the upstream face, removable the installing has the stiffener on two adjacent vertical guide rail relative a pair of installation departments in position, and the setting of many stiffeners can obviously improve the atress intensity of flood control baffle. Furthermore, the vertical guide rail is also provided with a plurality of reinforcing support structures, such as a plurality of triangular supports, so that the strength of the single vertical guide rail is improved.
As for the flood barrier, the submerged part and the volume of the flood barrier are substantially fixed, the buoyancy of the part is larger than the gravity of the whole flood barrier, in this embodiment, the part is the enlarged foot part, and in order to increase the buoyancy of the enlarged foot part, the inner part is a hollow structure, that is, the buoyancy of the hollow part in the water is larger than the gravity of the whole flood barrier.
Similarly, for the flood control baffle plate, in consideration of both strength and light weight, the flood control baffle plate can be in a hollow framework form, the outer surface of the flood control baffle plate is tightly wrapped by waterproof materials, the outer surface of the flood control baffle plate can be made of high-strength plastics, rubber and other materials, and the inner framework of the flood control baffle plate can be made of light-weight and high-strength steel structures or other alloy materials.
Since the flood barrier function is only activated in the high position, the function of the communicating section does not need to be maintained at all times, and the communicating section can be positioned higher at the exit point of the upstream face, even just a distance of a little lower than the top of the dam, e.g. 1 m. Alternatively, a valve structure can be arranged in the communication section to manually control the on-off state switching. Alternatively, the middle part of the communicating section is in an upward arched shape, and the vertex level of the arc-shaped part is higher than the communicating end of the communicating section and the outside and lower than the top opening of the storage section, so that water at low water level cannot cross the arc-shaped part and enter the storage section.
