Description

Technical Field

[0001] The invention relates to the technical field of flood control dams, and in particular to an anti-seepage water conservancy flood control dam structure. Background Art

[0002] At present, extreme weather in the region is showing an upward trend, the number of flood disasters and the losses are increasing year by year, and the construction of flood control dams is becoming more and more important in urban and rural development; flood control dams refer to dams built to prevent river flooding and protect the personal safety and property safety of residents living on the river bank. Flood control dams appeared hundreds of years ago. Usually, flood control dams are made of mud, stones or reinforced concrete.

[0003] After searching, it is found in the prior art that flood control is achieved by temporarily and quickly raising the height of the dam body. However, when the real flood arrives, the temporarily raised baffle is simply unable to stop the surging flood. What can really guarantee safety is the anti-collapse effect of the dam body in the flooded section. At this time, if it can be held for a long time, the rescue workers will speed up the reinforcement of the flooded position. Therefore, we propose a water conservancy flood control embankment mechanism that is anti-seepage. Summary of the invention

When pouring the concrete reinforcement layer, steel bars are driven into the deep places of the bottom and sides of the dam body at intervals to improve the tensioning and anti-extrusion collapse effects and firmly grasp the foundation, and a cast-in-place surface cover plate flush with the top of the dam body is fixed on the top of the concrete reinforcement layer, and the lower surface of the cast-in-place surface cover plate is in line with the concrete reinforcement layer on both sides. The upper surface of the cast-in-place surface cover plate is riveted; two rows of symmetrical sliding bearings are embedded near the middle, and vertically sliding lifting bars are slidably connected in the sliding bearings, and the bottom ends of the lifting bars are fixed with floating devices; two U-shaped support plates with openings upward and parallel to each other are fixed near the middle of the upper surface of the cast-in-place surface cover plate, and a folded net bag is fixed at the bottom of the groove of the U-shaped support plate, and the top of the net bag in the U-shaped support plate on the same side is fixed with the same fixed cross bar, which makes it easy to unfold the net bag, and the two fixed cross bars are respectively fixed to the top ends of the two rows of lifting bars; and the lower surface of the cast-in-place surface cover plate is provided with a one-way positioning mechanism compatible with multiple groups of each lifting bar; By setting a lifting barrier rod 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.
