An ecological cemented sand and gravel bank slope toe member

Abstract

The invention discloses an ecological cemented sand gravel bank slope toe component. The ecological cemented sand gravel bank slope toe component comprises a plurality of water-permeable water-facingsurfaces, a fixed surface and a connecting surface, wherein the water-facing surfaces, the fixed surface and the connecting surface form a regular or irregular closed polygonal slope toe; the connecting surface is obliquely arranged and is fixed to a bank slope; the fixed surface is horizontally arranged below the slope toe; one of the water-facing surfaces is vertically arranged on the fixed surface; a plurality of inlets and outlets are formed in the vertical water-facing surface on the slope toe at intervals; the water-facing surfaces comprise the following components: aggregate, a water reducing agent, a reinforcing agent, cement and diatomite; and the connecting surface and the fixed surface comprise the following components: sand gravel, fly ash and cement. According to the ecological cemented sand gravel bank slope toe component, the closed slope toe formed by the water-facing surfaces, the fixed surface and the connecting surface and raw materials for preparing each surface areadopted, so that the scouring of water flow to a cemented sand gravel dam body is effectively reduced, the engineering safety is improved, the engineering cost is saved, and meanwhile, a certain living space is provided for underwater organisms such as fishes.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower, and in particular relates to an ecological cemented sand and gravel bank slope toe member. Background technique [0002] The bank slope of traditional cemented sand and gravel dams is usually set up by grouting and vibrating cemented sand and gravel or normal concrete, and the slope toe is generally not treated. However, the slope toe of the embankment is often washed by longitudinal water flow; for rivers with large river width and turbulent flow, it is often necessary to consider setting up a certain length of horizontal anti-seepage bedding and extending to the river bed to better protect the bank slope , but this is often a large amount of engineering, and the cost of foundation treatment is relatively high, which makes the overall cost of the project relatively high. [0003] Conventional cemented sand and gravel embankments generally have a trapezoidal cross-sectio...

AI Technical Summary

Problems solved by technology

Slurry-rich cemented gravel or normal concrete bank slopes can generally avoid water erosion to a certain extent, but due to the hardening of the bank slope, water organisms such as fish, shellfish, and algae will lose their habitats, resulting in a decline in the number of water organisms in the river. decline
