Ecological slope protection composite retaining wall structure and construction method

Abstract

The invention discloses an ecological slope protection composite retaining wall structure which comprises an ecological abrupt slope and a basic retaining wall constructed along a bank slope of a reservoir. The ecological abrupt slope is located above the normal pool level. The basic retaining wall is located below the normal pool level. The basic retaining wall comprises a retaining wall step-type foundation and a retaining wall body. The retaining wall body is located above the retaining wall step-type foundation. The retaining wall step-type foundation is arranged on intermediary weathered rock below a basic slot excavation line. The ecological slope protection composite retaining wall structure is applicable to geological conditions with the large water level amplitude and abrupt slope, occupies the small flood control capacity of a reservoir, and can also be soaked into water for a long time. The invention further relates to a construction method of the ecological slope protection composite retaining wall structure.

Description

technical field [0001] The invention relates to a slope support structure, in particular to an ecological slope protection compound retaining wall structure, and also relates to a construction method of the ecological slope protection compound retaining wall structure. Background technique [0002] In water conservancy and hydropower projects, in order to meet the needs of flood control and power generation, the water level of the general reservoir varies greatly, and the flood control storage capacity of the reservoir cannot be encroached on much; for mountainous reservoir areas, the slope of the reservoir bank is steep. Therefore, the construction of roads along the river in Chengji towns in the reservoir area will be affected by various factors such as large fluctuations in the water level of the reservoir, poor geological conditions on the banks of the reservoir, and limited flood control capacity of the reservoir. Therefore, it is very important to choose appropriate ro...

Problems solved by technology

[0003] In the traditional retaining structure, backfilling with non-reinforcing ribs requires a large amount of earth and stone backfilling, and the project occupies a large area, so it will occupy a large flood control storage capacity of the reservoir and have a great impact on flood discharge; Although slopes can be used on steep slope banks and occupy a small reservoir capacity for flood control, they have poor water resistance due to long-term immersion, so they are not suitable for the riverside area of ​​the reservoir; traditional plant protection has poor erosion resistance. And it is not suitable for steep and long-term flooded slopes; the traditional retaining wall support wall structure is large in size and high in cost. Although it is stable, the urban landscape effect is poor, and the applicability to the riverside area of ​​the reservoir is also poor.
