Problems solved by technology

The process of damaging hard channels is mainly to dismantle them for re-construction, resulting in a lot of waste of resources and economic expenditure. On the other hand, there are still relatively few effective processes for ecological transformation of existing and newly built hard channels

Embodiment 1

[0031] A method for ecological transformation of a hard concrete channel, comprising:

[0032] 1) In the watershed irrigation area, select a hard concrete channel with a well-built U-shaped cross-section that has been built or newly built, and do a good job of manual cleaning. After cleaning up the weeds, silt, and garbage in the slope of the hard concrete base, use an impact drill to press Drill anchor holes at intervals of 1 meter, the depth of the anchor holes is 10cm, and the length of the inserted anchor nails is 80cm, which is required to be inserted into the soil layer about 5cm; In the end, it was less than one meter to the side of the canal, but the distance between the anchor nails and the side of the canal should not exceed 10cm, so anchor holes were also set at 10cm to prevent the unanchored part from being too large and the grille would be washed up by the water flow.

[0033] Step 2) The components by weight are: 85 parts of soil, 10 parts of water, 0.5 part of w...

Embodiment 2

[0038] A method for ecological transformation of a hard concrete channel, comprising:

[0039] Step 1) Select the damaged duplex-section hard concrete channels with cracks and collapses in the watershed irrigation area, do a good job of manual cleaning, clean up the weeds, silt, and garbage on the slope surface, and fill the pores with backfill soil. According to the terrain, use a percussion drill to drill anchor holes at intervals of 0.8 meters. The depth of the anchor holes is 15cm. Insert the anchor nails. The length of the anchor nails is 1m. It is required to insert about 5cm into the soil layer; Control the anchor holes to be set every 0.8 meters, and finally reach the side of the canal less than 0.8 meters, but the anchor nails can not exceed 10cm from the side of the canal, so anchor holes are also set at 10cm, in order to do a good job of anchoring and prevent the space of the unanchored part from being too large The large grille will be washed up by the water flow. ...

Embodiment 3

[0045] A method for ecological transformation of a hard concrete channel, comprising:

[0046] 1) In the watershed irrigation area, select a hard concrete channel with a trapezoidal cross-section that has been built or newly built, and do a good job of manual cleaning. After cleaning the weeds, silt, and garbage on the slope of the hard concrete base, use an impact drill according to 1.2 Drill anchor holes at intervals of 12 cm. The depth of the anchor holes is 12 cm, and the length of the inserted anchor nails is 80 cm. It is required to insert about 5 cm into the soil layer; It is less than 1.2 meters to the side of the canal, but the distance between the anchor nails and the side of the canal cannot exceed 10cm, so anchor holes are also set at 10cm to prevent the unanchored part from being too large and the grille will be washed up by the water flow.

[0047] Step 2) The components by weight are: 80 parts of soil, 8 parts of water, 0.3 part of water-retaining agent sodium m...

Abstract

The invention discloses am ecologicalized transformation method for a hard concrete channel and the biological hard concrete channel thereof. The method comprises the following construction steps: removing impurities of a slope of a hard concrete base layer, perforating anchoring holes and inserting anchoring nails; paving a layer of modified ecological soil and compacting the same, and scatteringgrass seeds; carrying out surveying and setting out, and piling to pave templates, paving plant concrete, removing the templates after maintenance, and pouring mixed slurry; after the mixed slurry isstabilized, paving a grating geonet gasket; and fixing the geonet gasket through the inserted anchoring nails, and maintaining the channel periodically. A soil layer, a plant concrete layer and a grating layer are successively and progressively protected by means of the plant concrete, the grating and the anchoring nails, so that the hard concrete channel is high in hydraulic impact resistance, high in plant rate and high in weather resistance and erosion resistibility. In-situ ecologicalized transformation is carried out by means of a damaged or an existing hard concrete channel, so that theresources are saved, removal of the hard concrete channel is avoided, and the method is economical.

Description

technical field [0001] The invention relates to the technical field of novel ecological channel construction, in particular to a method for ecological transformation of a hard concrete channel and the ecological hard concrete channel. Background technique [0002] The traditional ecological slope protection and bank revetment technology mostly uses concrete for protection. Although this "three-sided light" technology has good functions of wind protection, wave dissipation, water delivery and anti-seepage, it destroys the original river bank ecosystem and After a long period of time, in some areas with poor soil quality, hard concrete channels will crack and collapse to varying degrees, and lose the ability to store water, prevent seepage, and deliver water. Large-scale concrete solid waste has become a headache for water conservancy departments and water conservancy engineering companies to deal with and deal with. [0003] In recent years, the concept of ecological channel...
