Embodiment 1

[0021] The original urban river concrete embankment was poured with C20 concrete, with an average thickness of about 15cm and a slope of 1:2. It was put into use three years ago. Use DN160 PVC downpipes to cut 20 short pipes with a length of 15cm, and use DN160 PVC downpipes as the outer mold to pour porous concrete: the aggregate particle size is between 20 and 25mm, use 42.5 ordinary Portland cement, and the water-cement ratio is 0.3 (weight ratio, The same below), the gray-to-bone ratio is 1:8, and the thickness is 9cm. After curing at room temperature for 15 days, first spray with tap water, then spray with 10% oxalic acid solution to reduce the alkalinity of porous concrete to below pH 10, then fill with pond mud, dried sludge, peat soil, wood chips, water retaining agent polyacrylamide, Slow-release fertilizer (lawn controlled-release fertilizer, produced by Shenzhen Batian Ecological Engineering Co., Ltd.) is mixed according to the weight ratio of 210:380:390:20:3:0.5 a...

Embodiment 2

[0023] The original urban river concrete embankment was poured with C20 concrete, with an average thickness of about 15cm and a slope of 1:3. It was put into use three years ago. Use DN200 PVC drainage pipes to cut 30 short pipes with a length of 15cm, and use DN200 PVC drainage pipes as the outer mold to cast porous concrete: the aggregate particle size is between 20 and 25mm, use 42.5 ordinary Portland cement, and the water-cement ratio is 0.3 (weight Ratio, the same below), gray bone ratio 1:8, thickness 9cm. After curing at room temperature for 15 days, first spray with tap water, then spray with 10% oxalic acid solution to reduce the alkalinity of porous concrete to below pH 10, then fill with pond mud, dried sludge, peat soil, wood chips, water retaining agent polyacrylamide, Slow-release fertilizer (lawn controlled-release fertilizer, produced by Shenzhen Batian Ecological Engineering Co., Ltd.) is mixed according to the weight ratio of 300:300:400:15:2:0.4 and mixed wi...

Embodiment 3

[0025]The original urban river concrete embankment was poured with C20 concrete, with an average thickness of about 15cm and a slope of 1:2.5. It was put into use three years ago. Use DN100 PVC downpipes to cut 20 short pipes with a length of 15cm, and use DN100 PVC downpipes as the outer mold to pour porous concrete: the aggregate particle size is between 20 and 25mm, use 42.5 ordinary Portland cement, and the water-cement ratio is 0.3 (weight ratio, The same below), the gray-to-bone ratio is 1:8, and the thickness is 9cm. After curing at room temperature for 18 days, first spray with tap water, then spray with 12% oxalic acid solution to reduce the alkalinity of porous concrete to below pH 10, then fill with pond mud, dried sludge, peat soil, wood chips, water retaining agent polyacrylamide, Slow-release fertilizer (lawn controlled-release fertilizer, produced by Shenzhen Batian Ecological Engineering Co., Ltd.) is mixed according to the weight ratio of 280:320:390:20:3:0.5 ...

Abstract

The invention discloses a method for processing ecological modifying on the river concrete, which uses PVC short pipe as outer mould to be filled porous concrete; planting plant seeds after alkali reduction and filling vital stuffing; when the plants are 5-10cm high, moving the prefabricated elements into the round holes with relative sizes on the concrete bank; the holes has been smoothed and filled vital material; then filling the space between PVC pipe and concrete wall with sand pulp, to be compressed; and finishing the plants on the bank. The invention has simple device, lower cost and the application for ecological modifying of river concrete bank, while the modified bank has stable structure, anti-brush, and better economic and environment benefits.

Description

technical field [0001] The invention belongs to the fields of water conservancy engineering, environment and ecological restoration engineering, and in particular relates to a method for carrying out ecological transformation on concrete embankment slopes of river courses. Background technique [0002] Generally, the natural river course is meandering, and the waterfront vegetation coverage rate is high, so the water passing capacity is relatively weak. In order to prevent floods and reduce disasters, people have carried out concrete and stone masonry reconstructions on the embankment slopes of urban rivers. This is the current situation of most domestic urban rivers today. This kind of hard structure cuts off the exchange and circulation between soil and water in the berm, prevents the water and air circulation of the river and riverside vegetation, reduces the self-purification ability of the river, not only makes many terrestrial plants lose their living space, but also ...
