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 du

Embodiment Construction

[0038] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but it does not constitute a limitation of the present invention, and is only used as an example. At the same time, the advantages of the present invention will become clearer and easier to understand through the description.

[0039] like figure 1As shown, the ecological slope protection composite retaining wall structure of the present invention is built along the bank slope of the reservoir, including the ecological steep slope and the foundation retaining wall built under the ecological steep slope. The ecological steep slope is above the normal water storage level, and the foundation retaining wall is below the normal water storage level. The foundation retaining wall includes a stepped foundation 1 of the retaining wall, a body of the retaining wall 3 and a gravel filler 7 . The stepped foundation 1 of the retaining wall is set at the bott...

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...
