In the existing ecological restoration process, water in a polluted river channel is usually pumped out in advance, then the polluted sludge at the bottom is dug out, and then a clear water source is introduced to preliminarily improve the river channel.

Nevertheless be with the river course that above-mentioned mode was improved, still can receive serious pollution once more after a plurality of years under the sand blown by the wind in city and the pollution, need to spend manpower and materials again, cause the waste of resource and the improvement of cost, for solving this problem, the utility model provides a planting concrete block and a river course restoration ecosystem that river course restoration bottom protection was used respectively.

The utility model provides a planting concrete block that end was used is restoreed in river course, as shown in fig. 1 to fig. 3, includes geotechnological cloth layer 2, rubble bed course 3 and the concrete bottom layer 4 of protecting of laying in proper order by supreme down, planting concrete block 1 has been offered a plurality of planting holes 5 for rectangular array ground, the intussuseption in planting hole 5 is planted soil, planting soil is used for planting green plant, the diameter of planting hole 5 is 100 mm.

The specific working principle is as follows: geotechnological cloth layer 2 is used for keeping apart the silt of planting concrete block 1 and green plant and river course bottom, avoid river course silt to mix with planting soil, the root of green plant can extend to in the clearance in rubble bed course 3, and consolidate the green plant, concrete bottom protection layer 4 is used for consolidating the structural strength of river course bottom, algae or pasture and water etc. can be chooseed for use to the green plant, plant in planting the partial residue that the green plant in hole 5 can absorb and digest the river in, avoid the fermentation to cause river foul, can reduce the destroyed degree of river course from this, thereby improve the prosthetic cycle again of river course, reduce the waste of resource, reduce river course repair cost.

The length and the width of the planting concrete block 1 are 4000 mm; the square planting concrete blocks 1 are beneficial to the uniform distribution of the planting holes 5.

The distance between any two adjacent planting holes 5 in the same row or the same column is 1000 mm; if the spacing between adjacent planting holes 5 is too dense, the purification degree at the bottom of the river channel is uneven, and the nutrient absorption areas of the green plants are crossed.

The thickness of the gravel cushion layer 3 is 100mm, the concrete bottom protecting layer 4 is formed by filling C20 sand-free concrete, and the thickness of the concrete bottom protecting layer is 200 mm; the thickness of each layer is determined by combining various factors such as construction difficulty, green plant growth requirement and the like.

The utility model provides a river course repair ecosystem, includes the river course, a plurality of along the setting of river course length direction and as in above-mentioned technical scheme plant concrete piece 1 to and set up the reinforced concrete frame grillage 6 between two adjacent planting concrete pieces 1.

The reinforced concrete frame grillwork 6 can separate two adjacent planting concrete blocks 1, on one hand, the construction is convenient, the construction can be carried out one by one according to the sizes of the planting concrete blocks 1, and on the other hand, the layer structures of the two adjacent planting concrete blocks 1 are prevented from mutually permeating.

The bottom of the reinforced concrete frame grillwork 6 is also provided with a broken stone cushion layer 3 with the thickness of 100 mm; further reinforcing the structural strength of the reinforced concrete frame grillwork 6.

The length of the reinforced concrete frame grillwork 6 is 400 mm; the reinforced concrete frame grillage 6 at two ends of the same planting concrete block 1 is clamped together, the layer structure is not damaged, the reinforced concrete frame grillage 6 cannot be too long, otherwise, the ratio of planting the concrete block 1 at the bottom of the river channel is too low, and the better continuous repairing effect cannot be achieved.

The utility model discloses utilize and evenly lay planting concrete block 1 along length direction in the river course bottom to plant green plant on planting concrete block 1, let green plant absorb the residue in the river, with the ecological remediation that reaches the river, thereby let river course self have self-repairing ability, the extension is prosthetic cycle once more, reduces the wasting of resources.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
