Problems solved by technology

[0003] Traditional bank revetment only pays attention to the durability of the project, and is mostly built with building materials such as cement, mortar, stone, concrete, reinforced concrete and asphalt. The bank revetment buildings built with these building materials can maintain the stability of the bank slope and prevent water and soil Water loss and flood control safety have played an important role, but the impact of

Embodiment 1

[0017] see figure 1 , figure 2 and image 3 , an ecological prefabricated block bank revetment for ordinary rivers, the base 7 is cast in-situ with mortar block stone or concrete, the bottom elevation of the base 7 goes deep below the design minimum scour line, and has a certain safety margin to ensure the safety of the revetment . A fish nest type cavity block 1 and a plant type cavity block 4 are built on the base 7 . During masonry, fish nest type cavity blocks 1 are used for the underwater part submerged all the year round, and plant type cavity blocks 4 are used for the above water part. The fish nest type cavity block 1 can be built into a vertical or stepped revetment pattern, so that fish can enter and exit from the hole conveniently. But plant type cavity block 4 should be built into stepped revetment pattern, so that plant plant above the step.

Embodiment 2

[0019] see figure 1 , figure 2 and Figure 4 , an improved structure for revetment of urban rivers, especially the rivers in the old urban areas with many buildings, restricted by the buildings on both sides, the cross section is often rectangular. Although the rectangular section saves land, it is poor in ecology, ornamental and hydrophilic. For this reason, some concrete cavity prefabricated blocks can be arranged along the river banks on the water side of the original concrete or masonry revetment 8. The fish nest-type cavity block 1 arranged in the lower part provides a habitat for various wild aquatic organisms; the plant-type cavity block 4 arranged in the upper part can plant aquatic plants 10 . Aquatic plants can absorb and transfer pollutants in river water and inhibit the growth and development of bath plants, which play an important role in controlling eutrophication in river water and improving water quality. In addition, plant-type cavity blocks 4 can be set ...

Abstract

The invention discloses an ecotype prefabricated building bock bank revetment. The upper part is built by dryly laying plant type cavity building blocks, and the lower part is built by dryly laying fish nest type cavity building blocks; the plant type cavity building blocks are built into a stepped bank revetment and are provided with top-to-bottom cavities; the cavities of the plant type cavity building blocks are filled with an earth material in which plants are planted; the fish nest type cavity building blocks are provided with run-through cavities in water flow direction and are provided with holes on the water side; the fish nest type cavity building blocks and the plant type cavity building blocks are made of water-permeable concrete or water-impermeable concrete; and when the cavity building blocks are made of the water-impermeable concrete, the back side is provided with water-permeable holes. The bank revetment has a certain structural strength, is resistant against scour and has a protection effect on the revetment; the cavity structure of the building block meets an ecological design principle and contributes to plant growth and small organism propagation; and the building blocks are water-permeable, are used for communicating an aquatic ecosystem with a land ecosystem and have a certain natural purification effect on water pollution.

Description

technical field [0001] The invention belongs to the field of revetment engineering, in particular to an ecological prefabricated block revetment. Background technique [0002] Due to the action of water flow, wind and waves, etc., the embankment or river bank will be scoured and damaged. This damage will not only cause the destruction of a large amount of cultivated land on the bank, aggravate the siltation of the downstream river, but also endanger the safety of flood control, industrial and agricultural production and shipping on both sides of the bank. Therefore, proper protection of the embankment is very necessary. The buildings used to protect the embankment are collectively called revetment works. Bank revetment is an effective measure to prevent embankment from being damaged by erosion. [0003] Traditional bank revetment only pays attention to the durability of the project, and is mostly built with building materials such as cement, mortar, stone, concrete, reinfo...
