The invention discloses a construction method of an ecological revetment for river bank protection. The construction method comprises the following steps of a, paving a gravel material cushion layer;b, paving geotechnical cloth; c, backfilling a soil layer with the depth of 20-30 cm on the geotechnical cloth, and compacting the soil layer; d, constructing the ecological revetment; and e, placingsoil into ecological planting holes of ecological building blocks, and then growing plants. According to the construction method, the ecological building blocks after construction cannot fall off, sothat the overall performance of the whole ecological revetment is improved, and the flood prevention effect, the ecological effect, the landscape effect and the self-cleaning effect of the ecologicalrevetment are enhanced; and meanwhile, accumulated water on the construction site can flow into the inclined surface parts of the ecological building blocks through filter plates used for lapping withthe building blocks, and the water on the inclined surface parts of the ecological building blocks are discharged into the soil through drainage grooves, so that the earthwork of the construction area which is not paved with the ecological building blocks is prevented from being subjected to micro-amplitude sedimentation phenomenon, the flatness of the excavated earthwork is guaranteed, the ecological building blocks can be conveniently and quickly laid, moreover, the ecological building blocks can be quickly replaced, and the service period of the ecological revetment can be prolonged.

The invention discloses a control method of an automatic flood prevention early warning and evacuation system in a waterfront area, comprising: step A. the control center authorizes the activation of an alarm device to broadcast warning and evacuation information; Enter, start the evacuation of the personnel on the hydrophilic platform; step C. judge whether the evacuation of the personnel on the hydrophilic platform is completed, if so, execute step D, otherwise return to step B; step D. the control center controls the gate drive device to drive the flood control gate from the gate Move out of the warehouse and close the gate of the hydrophilic platform; step E. The control center confirms that the tide has passed according to the feedback information, the flood control gate is returned to the gate warehouse, the gate of the hydrophilic platform is opened, and the automatic access control system opens the two-way entry and exit function. The present invention not only saves manpower and material resources, but also avoids potential safety hazards in manual operation, more flexibly allocates resources, and increases the utilization rate of waterfront areas while achieving better flood control effects.

The invention discloses a flood prevention device, which comprises a protective plate, a waterproof sealing component, a side push component and a positioning component. The protective plate is arranged in the middle of a door opening; the waterproof sealing component comprises a lower end seal installed on the side of the protective plate and two side edges Seal; the side thrust assembly includes the lower end push plate, the side push plate and the linkage assembly that are slidably arranged on the surface of the protective plate. The linkage assembly is used to make the lower end push plate connect the lower end seal and the side push plate to the corresponding The side seal is pushed to the corresponding inner wall of the door opening; the fixed positioning group of the positioning component is a fixed pin installed on the side wall of the protective plate and the mounting hole on the inner wall of the door opening corresponding to each other, and its movable positioning group includes a guide socket, a connecting rod group and a latch , the guide hole is installed on the surface of the protective plate, and the connecting rod group is connected to the side push plate on the second side. When the side push plate moves to the inner wall, the bolt is inserted into the corresponding inner wall along the guide hole. In the hole, the invention can improve the flood control efficiency.

The invention discloses a simple and convenient flood protection wall, which comprises a hard casing. The inside of the hard casing is a hollow cavity which is filled with packing materials, the hard casing is provided with a feed inlet and a discharge outlet, the packing materials can be fed from the feed inlet and discharged from the discharge outlet, connecting structures integrated with the adjacent hard casing are arranged on the left side and the right side of the hard casing, and a material layer which expands when absorbing water is arranged at the bottom of the hard casing. The simple and convenient flood protection wall is reasonable in structure, fine in flood protection effect, low in cost, convenient in transport and can be recycled.

The invention discloses an intelligent flood protection fence, and belongs to the field of flood protection and disaster relief. The intelligent flood protection fence aims to solve the problems that existing flood protection methods and flood protection devices are high in cost, high in manpower consumption and poor in flood protection effect. The intelligent flood protection fence comprises fence plates, supporting rods connected to the fence plates and fixed piles located at the lower ends of the fence plates; the fence plates are of a wave shape or a flat shape, comprise 3-5 fence plate bodies and are integrally formed; the supporting rods are connected to the fence plates in a twisted mode; and fixed buckles are arranged at one ends of the fence plates, and fixed clamping grooves matched with the fixed buckles are formed in the other ends of the fence plates. The intelligent flood protection fence can be used on occasions such as river heightening and reinforcing and urban inland inundation protecting.

The invention discloses a water conservancy river revetment. The water conservancy river revetment comprises more than one revetment rod laid on the river revetment, wherein a first baffle plate is arranged at the top of each revetment rod in a protruding mode, the first baffle plates are close to one side of the top of a slope surface and are used for blocking water on a slope top, and a buried box is arranged at the bottom of each of the more than one revetment rod; a second baffle plate is arranged in each buried box, a movable cavity with an opening in the upper end face is formed in eachburied box, each second baffle plate is telescopically arranged in the corresponding movable cavity, a ground insertion pipe is arranged at the bottom of each buried box and faces the corresponding revetment rod, and a sealed channel is formed in each ground insertion pipe. According to the water conservancy river revetment, rainwater on the slope tope can be effectively collected in rainy weather, the second baffle plates are lifted upwards by utilizing the weight of the rainwater, soil loss is reduced, the rising height of river water in a river is increased, and a good flood prevention effect is achieved.
