Problems solved by technology

[0002] The amount of dredged silt produced in the comprehensive treatment of rivers, lakes, tidal flats and the dredging of port channels is increasing day by day. Due to the high water content, high liquid limit, high compressibility, low strength, poor water permeability and slow consolidation rate of dredged silt , low shear strength, etc., and its engineering properties are extremely poor. Considering factors such as ecological environment and land resources are increasingly tense, the previous treatment methods of simply discarding or stacking dredged silt can no longer adapt to economic and social development.

Embodiment 1

[0030] A kind of silt ceramsite concrete ecological slope protection construction method, such as figure 1 and figure 2 shown, including the following steps:

[0031] The first step, undisturbed soil slope 1 trimming and slope cutting

[0032] The sundries on the surface of the original soil slope 1 are removed, and the original soil slope 1 is trimmed, slope cut, and compacted according to the slope ratio and structural requirements for forming slope protection.

[0033] The second step, pouring silt ceramsite concrete 2

[0034] According to the needs, pour the bottom beam 7 at the foot of the slope and set up wooden piles 8 to protect the bottom of the silt ceramsite concrete ecological slope protection, excavate a certain depth of foundation soil at the top of the slope, and pour silt ceramsite concrete as the roof protection structure, Form the top beam 9.

[0035] A 12cm-thick silt ceramsite concrete 2 is poured on the slope after slope protection. The cast-in-place...

Embodiment 2

[0044]The difference between this embodiment and Embodiment 1 is that in the second step, the silt ceramsite concrete 2 is laid in layers on the slope to be treated, and each layer of silt ceramsite concrete is inserted and rammed to form and make holes. And the matrix balls are filled into the holes of each layer of silt ceramsite concrete, which can not only serve as the soil required for plant growth, but also provide the required fertilizer for plant growth. After the matrix balls are pulverized, connected pores can be formed between the matrix balls, which further meets the requirements of the pores for good plant growth. The matrix ball is a spheroid made by mixing soil, slow-release fertilizer, organic matter, and water-retaining materials. The particle size is 5mm to 10mm. Organic matter 3%, water-retaining material 3%. The preparation process of the matrix ball is as follows: mix the soil, slow-release fertilizer, organic matter, and water-retaining materials accordi...

Abstract

The invention provides a sludge ceramsite concrete ecological revetment construction method, comprising the following steps that 1, an original soil slope is trimmed and cut; 2, sludge ceramsite concrete is poured on a slope surface to be treated; 3, nutrient soil and planting soil are sequentially laid on the sludge ceramsite concrete; 4, aquatic plants and turf are planted on the revetment; and5, the planted plants are maintained. According to the invention, the sludge ceramsite concrete revetment technology is matched with landscape greening, the ecological greening revetment avoids the problem that a traditional revetment is insufficient in greening, guarantees that plants can root in the revetment soil more easily while meeting the safety and stability of the revetment, is suitable for projects such as river, lake and sea water system and black and odorous riverway governance and road traffic, and achieves the effects of fixing soil, protecting the revetment, governing pollution,improving ecology and beautifying the environment.

Description

technical field [0001] The invention relates to a construction method for silt ceramsite concrete ecological slope protection, and belongs to the technical field of ecological slope protection. Background technique [0002] The amount of dredged silt produced in the comprehensive treatment of rivers, lakes, tidal flats and the dredging of port channels is increasing day by day. Due to the high water content, high liquid limit, high compressibility, low strength, poor water permeability and slow consolidation rate of dredged silt , low shear strength, etc., and its engineering properties are extremely poor. Considering factors such as ecological environment and land resources are increasingly tense, the previous treatment methods of simply discarding or stacking dredged silt can no longer adapt to economic and social development. [0003] In recent years, the use of waste such as silt as the raw material for the production of ceramsite to generate silt ceramsite can not only ...
