Embodiment 1

[0021] Take the regular quadrangular prism planted row grid as an example, such as figure 1 , 2 As shown, peat, raw soil, and water moss are mixed in a volume ratio of 1:1:0.5 to form a planting matrix 1, and aquatic plant seeds or branches of aquatic plants are evenly added to the planting matrix 1. Wrap the planting substrate 1 with a water-filtering geotextile 2, cast sand-free concrete 3 around the wrapped planting substrate 1, press the mold to form a regular quadrangular prism planting-type sash unit 4, and the four sides of the regular prism planting-type sash unit The length is 80 cm, and the thickness is 5-10 cm. The coupling hooks 5 are respectively arranged at the center of two sides of the regular quadrangular prism planting type sash unit 4, and the hook rings 6 are respectively arranged at the remaining two sides of the regular square prism planting type sash unit 4. center of.

Embodiment 2

[0024] Taking the cylindrical planting type row grid as an example, mix peat, raw soil, and water moss at a volume ratio of 1:1:0.5 to form a planting substrate 1, and evenly add aquatic plant seeds or insert aquatic plants into the planting substrate 1. Plant branches. Wrap the planting substrate 1 with a water-filtering geotextile 2, cast sand-free concrete 3 around the wrapped planting substrate 1, press the mold to form a cylindrical planting-type sash unit 7, and the diameter of the cylindrical planting-type sash unit 7 is 80cm , with a thickness of 5-10 cm, the coupling hooks 5 are respectively arranged on the two quartering points on the middle section circle of the cylindrical planting type sash unit 7, and the hook rings 6 are respectively arranged on the cylindrical planting type sash On the remaining two quarter points on the middle section circle of unit 7.

[0025] Such as Figure 4 As shown, when the present invention is used to repair the river bed base, the v...

Abstract

The invention provides a riverbed base vegetation type unit sash repair method. The method comprises the steps of: covering vegetation ground substance by water filtering type geotextile, and closing the periphery by concrete without sand; forming vegetation type sash units by pressing with a mould; preparing the vegetation ground substance by mixing peat, raw soil and water moss by volume proportion; uniformly adding aquatic plant seeds in the vegetation ground substance or interplanting aquatic plant branches in the vegetation ground substance; interlinking all of the vegetation type sash units by combination hooks and staples for forming the vegetation type unit sashes; and laying the vegetation type unit sashes at the river bottom smoothly. The invention solves the problems of the difficulty of aquatic plant repair at the riverbed with deeper silt, and the damage to riverbed microecosystem caused by desilting and dredging. Inner source pollution caused by the release of infectant in substrate sludge to water can be effectively restricted, and all of the used materials are environmental friendly. When used, the sashes can be installed and laid conveniently on site, and have low cost and obvious effect.

Description

technical field [0001] The invention relates to an ecological river channel construction technology, in particular to a technology for repairing the living environment of river bed substrates, inhibiting the release of sediment pollutants and purifying river water bodies by using plant-growing row grids. Background technique [0002] There are a large number of pollutants deposited in the sediment of rivers, lakes and reservoirs, such as nitrogen and phosphorus nutrients, toxic and harmful substances that are difficult to degrade, and heavy metals. Under certain conditions, they will dissolve from the sediment and re-enter the water body to form endogenous pollution. The water quality of rivers and lakes deteriorates and becomes another major pollution source of water bodies. At present, the main technologies used to eliminate endogenous pollution include sediment oxidation, sediment covering, and sediment dredging. [0003] Sediment oxidation is the use of chemicals such a...
