An ecological and economical revetment structure

Abstract

The invention discloses an ecological and economical bank revetment structure, which comprises sequentially setting pile foundations, steel-plastic composite geogrids, riprap prisms, gravel inverted filter layers, geotextiles and backfilling planting soil from the water side of the bank revetment to the shore The revetment is equipped with a viewing platform; the viewing platform is equipped with multi-functional guardrails; the pile foundations are connected into a whole with concrete beams; the steel-plastic composite geogrid is closely attached to the pile foundations, and its upper part is bent and paved to the viewing At the end of the platform, the lower part is bent and pressed under the riprap prism; soil-fixing vegetation with well-developed root system is planted on the backfilling planting soil. The invention utilizes the energy dissipation and decompression effects of the riprap prism and the excavation-free characteristics of the pile foundation, and has the characteristics of simple structure, strong erosion resistance, small construction work surface, short construction period, low cost, and ecological landscape functions. , to realize the ecological function of the green channel revetment and the safety and economic performance of the structure.

Description

technical field [0001] The invention relates to the field of revetment construction in the regulation of inland waterways such as river banks, dams and waterways, and in particular relates to an ecological and economical revetment structure. Background technique [0002] Water transportation is a very economical mode of transportation. Due to the development of water transportation, many inland waterways need to be widened and improved. The revetment structure used as a waterway must first be stable and economical. In the existing inland waterway, the main structural types of revetment are dry block stone, mortar block stone, cast-in-place concrete, prefabricated concrete block, geotechnical bag concrete, rope hinge concrete plate, etc., all of which belong to rigid revetment. Starting from the protective function of the slope, it plays an important role in resisting the erosion of the bank slope by water flow and ship waves, maintaining the stability of the bank slope, avoi...

AI Technical Summary

Problems solved by technology

However, this type of bank revetment is mainly based on rigid bank revetment, and then land ecological slope protection, which is expensive, and the water body in the channel does not actually exchange with the water body on the bank slope, and realizes the landscape function, but it is not the real meaning. Ecological waterway, green waterway
