Ecotype prefabricated building bock bank revetment

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.

AI Technical Summary

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 these buildings on organisms and the ecological environment has not been considered, ignoring that rivers are also living ecosystems

These impermeable buildings cut off the connection between the water ecosystem and the terrestrial ecosystem, destroying various ecological processes of the river, resulting in the reduction of the river's self-purification and self-recovery ability, and the serious pollution of the river water.
