Description

Technical Field

[0001] The present invention relates to the technical field of flood control dikes, and particularly to an anti-seepage water conservancy flood control dike structure. Background Art

[0002] Generally, flood control dikes are made of piled-up soil, built with stones, or cast with reinforced concrete, aiming to protect the personal and property safety of residents living on the riverbank.

[0003] After retrieval, it is also found in the prior art that the flood control effect is achieved by temporarily and quickly increasing the height of the dam body. However, when the real flood arrives, that layer of temporarily increased baffle is simply unable to block the surging flood. What can truly ensure safety is the anti-collapse effect of the dam body in the overtopping section. If it can hold on for a long time at this time, the rescue personnel will speed up the reinforcement of the overtopping position. Therefore, we propose an anti-seepage water conservancy flood control dike mechanism. Summary of the Invention

[0004] Aiming at the technical problem in the prior art that a reinforced plate that automatically rises temporarily cannot block floods, the present invention adopts the following technical solutions:

The two sides of the dam body are respectively a riverbed and a human activity area; the ground height of the human activity area is higher than that of the riverbed side, and a main groove parallel to the extension direction of the dam body is reserved on the top of the dam body near the riverbed side. A concrete reinforcement layer is fixed on the bottom of the main groove and the vertical side walls on both sides. When pouring the concrete reinforcement layer, steel bars are driven into the bottom and side of the dam body at intervals to improve the tensioning and anti-extrusion collapse effects and firmly grasp the foundation. The top of the concrete reinforcement layer is fixed with a cast-in-place surface cover plate flush with the top of the dam body. The two sides of the lower surface of the cast-in-place surface cover plate form a riveting relationship with the concrete reinforcement layer; two rows of symmetrically arranged sliding bearings are embedded near the middle of the upper surface of the cast-in-place surface cover plate, and vertical sliding lifting stop bars are slidably connected in the sliding bearings. Floating devices are fixed at the bottom ends of the lifting stop bars. Two parallel U-shaped brackets with upward openings are fixed near the middle of the upper surface of the cast-in-place surface cover plate. A net pocket folded together is fixed at the bottom of the U-shaped brackets. The top ends of the net pockets in the same side of the U-shaped brackets are fixed to the same fixed cross bar. The fixed cross bar is provided to facilitate the unfolding of the net pocket, and the two fixed cross bars are respectively fixed to the top ends of the two rows of lifting stop bars; and a plurality of one-way positioning mechanisms adapted to each lifting stop bar are arranged on the lower surface of the cast-in-place surface cover plate.

[0006] By setting up a lifting and lowering lever that rises as the water level rises, and cooperating with the net bag that rises together, when the water level is about to overflow the top of the dam, it will first enter the bottom of the groove of the concrete reinforcement layer below the top of the dam from the preset seepage opening. At this time, the retaining wall composed of two net bags can be slowly raised in advance, and then sandbags can be stacked between the two net bags to effectively block the impact of the flood.

[0016] The beneficial effects of the present invention are:

[0017] 1. By setting a lifting barrier that rises with the water level and cooperating with the net bag that rises together, when the water level is about to overflow the top of the dam body, it will first enter the bottom of the concrete reinforcement layer below the top of the dam body from the preset seepage port. At this time, the retaining wall composed of two net bags can be slowly raised in advance, and then sandbags can be stacked between the two net bags to effectively block the impact of the flood. The net bags and lifting barrier bars are usually hidden to reduce exposure to the sun and other damage, thereby reducing maintenance costs.

[0018] 2. The one-way positioning mechanism can ensure that the lifting bar will not fall when in use, so as to prevent the floating mechanism from accidentally losing buoyancy when the water rises and causing the lifting bar to fall; the U-shaped support plate can protect the folded net bag and the fixed cross bar in the U-shaped support plate at ordinary times.

[0019] 3. By setting up active drainage ditches, when floods overflow the top of the dam, overflow can be avoided. The water will first be discharged from the active drainage ditches with surface hardening treatment to prevent overflow from other vegetation belts of the dam and cause soil erosion. The anti-scour bags set up can reduce the scouring of the active drainage ditches. The anti-scour bags can be rolled up after the flood to reduce the cleaning of silt.
