Embodiment 1

[0021] The ecological restoration project of river revetment adopts ecological concrete technology. first select as image 3 The ecological concrete block 4 has an external dimension of 390×190×190mm, the porosity of the ecological concrete is 15-20%, and the strength reaches 10N / mm 2 .

[0022] Then, carefully clean up the foundation platform of the original revetment 1 and the wall surface of the revetment 1 before lining the ecological concrete block 4, and remove debris such as sludge. Since the base platform may have an outward inclination, a leveling layer is required.

[0023] Then, smear cement mortar or cement paste on the large surface of an ecological concrete block 4, and press it onto the leveling concrete. The opening direction of the block 4 is perpendicular to the revetment 1, connected in a row to form the first layer of masonry. The lime-sand ratio of cement mortar is 1:1-2, and the water-cement ratio is 30-40%. The water-cement ratio of the cement slurr...

Embodiment 2

[0031] Apply a special adhesive on the opening surface and the top surface of a block, press it onto the second layer of masonry, and bond the top surface to the flood control wall. The blocks, with their openings pointing towards the sky, are connected in rows to form a third layer of masonry. One end of the block can adopt a shape such as a semicircle to form a wavy "row flowerpot".

[0032] Apply a special adhesive on the inner opening surface of the third layer of masonry, and apply a special adhesive on the large surface and top surface of another block, and build it on the third layer of masonry, and the large surface and the top surface of the third layer of masonry. The revetment is bonded. The blocks, with their openings pointing towards the sky, are connected in rows to form a fourth layer of masonry.

[0033] The fourth layer of masonry is repeated, and the fifth layer of masonry is formed by staggered masonry.

[0034] Pointing the third, fourth and fifth storey...

Abstract

The invention relates to a ecological repair method of concrete or cement rock waterfront, providing a ecological repair method of waterfront. It comprises: selecting large-hole concrete block (4); using cement sand pulp or cement pulp on the base platform (2) of waterfront to build ecological concrete blocks (4) while the holes of lower blocks are horizontal and the holes of upper blocks (4) are vertical; and filling mud (5) into the holes of higher blocks (4); than planting plants to form a view of grouped flowerpots or using hanging method to adhere the ecological concrete blocks (4) on the waterfront via brackets (7) and mud nail or expansion screw (8). The invention has lower cost, easy operation and the application to keep former invest level, while the root of planted plant can enter the slits of concrete to form firm combination to confirm the continuity of around water environment and ecological environment.

Description

Technical field: [0001] The invention relates to an ecological restoration method for revetments, and belongs to the technical field of reconstruction or ecological restoration of water bodies such as river courses. Background technique: [0002] The natural bank slopes of rivers and other water bodies are often prone to collapse due to the erosion of water flow, so most water bodies such as urban rivers are built with artificial revetments. The structural materials for building revetments are generally cement concrete or masonry rubble. Because cement concrete or masonry masonry is impervious to water and air, organisms cannot grow, which destroys the natural ecological environment of the river, makes the river lose its natural purification function, and water quality deteriorates. Although, in recent years, the revetment structure and material with the function of restoring ecology have been researched and developed, that is, ecological concrete....
