Ecological retaining wall structure and construction method thereof

Abstract

The invention provides an ecological retaining wall structure and a construction method thereof, and relates to the field of hydraulic engineering. The ecological retaining wall structure comprises a retaining wall foundation, a retaining wall support body and an ecological block, wherein the retaining wall foundation is arranged in a soil body of a river channel; the retaining wall support body comprises a retaining wall body and a retaining wall bottom block, and the retaining wall bottom block is arranged at the lower end of the retaining wall body and extends to one side of the retaining wall support body; the ecological block comprises backfill soil of a retaining wall part and a plurality of block bodies arranged on the backfill soil of the retaining wall part; a plurality of soil-water connection channels are arranged on the retaining wall support body, and the backfill soil of the retaining wall part extends to backfill soil of a bank wall part through the soil-water connection channels. According to the ecological retaining wall structure and the construction method thereof, the retaining wall foundation is constructed on the bank of the river channel, the upper portion of the retaining wall foundation is provided with the retaining wall support body, and the ecological retaining wall structure is formed by combining the retaining wall foundation and the retaining wall support body; horizontal force and other loads exerted on the ecological retaining wall structure are borne by the retaining wall foundation and the retaining wall support body together, so that the ecological retaining wall structure has the advantages of being safe, stable and reliable, and can meet the requirements for relatively narrow construction space, an ecological and environmental-protection effect, landscaping and the like.

Description

technical field [0001] The invention relates to the field of hydraulic engineering, in particular to an ecological retaining wall structure and a construction method thereof. Background technique [0002] With the development of modern urban construction, more and more cities have proposed the concept of building sponge cities and ecological cities, and the requirements for urban river regulation are getting higher and higher, often requiring the construction of ecological retaining walls. Because the traditional urban river improvement is mainly to meet the needs of urban flood control, the retaining wall generally adopts the traditional gravity mortar masonry retaining wall and concrete retaining wall. After they are built, the river water and the soil are artificially separated. Free exchange of water and soil is formed, and over time, the river cannot be purified by itself, and finally becomes a stinky river. In order to make the river ecological and exchange water, loca...

Because the traditional urban river improvement is mainly to meet the needs of urban flood control, the retaining wall generally adopts the traditional gravity mortar masonry retaining wall and concrete retaining wall. After they are built, the river water and the soil are artificially separated. Free exchange of water and soil is formed, and over time, the river cannot be purified by itself, and finally becomes a stinky river. In order to make the river ecological and exchange water, local governments spend hundreds of millions or even billions of funds every year, and it is thankless; It is the same color as concrete, which cannot beautify the environment, let alone adapt to the surrounding environment; in addition, because the existing structures such as roads and houses in the urban area are often close to the river, the construction space is relatively narrow, so it is difficult to construct Traditional Gravity Masonry and Concrete Retaining Wall Structures

At present, in areas where the construction space is relatively narrow, there is no structure that can not only meet the needs of urban flood control, but also achieve the functions of ecological protection and beautifying the urban landscape.
