Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the flood control dam structure comprises a reinforcing layer 1 arranged on the slope surface 4 of a river channel. The reinforcing layer 1 is divided into two sections, which are an ascending layer 2 and a descending layer 3 from top to bottom in sequence.

As shown in fig. 2 and 3, the ascending layer 2 includes a reinforced concrete framework, the reinforced concrete framework includes square cells 21, and the cells 21 are arranged on the river slope 4 in a rectangular array. The unit lattices 21 are filled with planting soil 22, one side of the planting soil 22 of the unit lattices 21, which is far away from the river slope 4, is paved with a protective belt 23, and four protective belts 23 are paved in one unit lattice 21. One end of the guard belt 23 abuts against the upper side edge of the cell 21 and is embedded in the planting soil 22, and the other end of the guard belt 23 abuts against the lower side edge of the cell 21 and is embedded in the planting soil 22. The four protective belts 23 are laid in the cell 21 in sequence along the upper side of the cell 21, the projections of all the protective belts 23 on the river slope 4 are equal to the area of the cell 21, the overlapping parts exist between the projections of the two adjacent protective belts 23 on the river slope 4, and the overlapping parts do not exist between the projections of the two non-adjacent protective belts 23 on the river slope 4. The direction of the river flow is from upstream to downstream, and in two adjacent guard bands 23 in one cell 21, the guard band 23 near the upstream of the river overlaps the upper side of the guard band 23 far from the upstream of the river. Each protective belt 23 is provided with an air hole 24. A reinforcing mesh 25 is fixedly arranged in the cell 21, the reinforcing mesh 25 is formed by mutually staggering a plurality of reinforcing steel bars, and the two ends of the reinforcing steel bars are poured in the reinforced concrete together. A steel wire mesh 26 is buried in the planting soil 22 in the unit lattice 21, and the steel wire mesh 26 in the unit lattice 21 is fixedly bound on one side of the steel wire mesh 25 away from the river slope 4 through an iron wire.

As shown in fig. 4 and 5, the downhill layer 3 includes building blocks 31, the cross section of the building blocks 31 is smaller than that of the cells 21, the building blocks 31 are arranged on the river slope 4 in a rectangular array, and the distance between the side of the building blocks 31 far away from the river slope 4 and the river slope 4 is greater than the distance between the side of the cells 21 far away from the river slope 4 and the river slope 4. The side of the building block 31 far away from the river slope 4 is provided with a square through hole 32, the through hole 32 is filled with planting soil 22, and the volume of the planting soil 22 is two thirds of the inner space of the through hole 32. Also buried wire net 26 in running through hole 32, wire net 26 is buried in planting soil 22, still lays the protection piece 33 that the size equals with running through hole 32 cross section in running through hole 32, and protection piece 33 is laid in planting soil 22 and is kept away from river course domatic 4 one side, has also seted up a bleeder vent 24 on the protection piece 33. All seted up connecting hole 34 on four medial surfaces that run through hole 32, and connecting hole 34 all sets up on the central line of medial surface, and the distance between the side of building block 31 keeping away from river course domatic 4 and connecting hole 34 is all equal.

The reinforcing layer 1 is divided into an ascending layer 2 composed of a reinforced concrete skeleton and a descending layer 3 composed of blocks 31 stacked. Under the effect of reinforced concrete skeleton and reinforcing bar net 25, fine reinforcement river course domatic 4, the structural strength of flood control satisfies the requirement. And because the water level of the river is not easy to overflow the ascending layer 2 in the dry season, the ascending layer 2 is set to be in a structure with larger area in direct contact with the slope body, so that the greening planting is convenient, the greening effect is good, and the ecology of the river channel slope protection is well protected. And the downhill path layer 3 is located the liquid level downside throughout the year, consequently sets up to more compact stable structure, compares in the uphill path layer 2, can better bear rivers and erode, is difficult for leading to planting soil 22 to be washed away to run through the planting soil 22 in the through-hole 32 and also can plant some plants, improve the afforestation effect. In flood season, when the plants in the upper unit cells 21 do not grow completely, the protective belts 23 can shield the planting soil 22, and river water is not easy to directly contact the planting soil 22 when flowing through the protective belts 23, so that the amount of the planting soil 22 which is rolled by the river water is less, and the plants in the planting soil 22 can grow conveniently.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
