Detection method for anti-filtration capability of vegetation concrete

Abstract

The invention discloses a detection method for the anti-filtration capability of vegetation concrete. The method comprises the following specific steps: 1, selecting and drying soil on a bank slope; 2, pouring dry soil test blocks into test sieves, sufficiently jolting the test sieves on a standard jolting sieve shaker, weighing the mass of the soil left on the test sieves of each aperture stage, and calculating the accumulated mass of the soil left on the test sieves, the mass percentages of the soil smaller than the apertures and the total mass percentages of the soil smaller than the apertures; 3, drawing a soil particle size distribution curve chart according to the test data, and calculating a uniformity coefficient and curvature coefficient of soil particles according to the soil particle size distribution curve chart; 4, estimating the anti-filtration capability; 5, performing data analysis. The method is scientific in principle, easy to operate and accurate in test data, site construction links can be reduced, site operation time can be shortened, adaptability to various site construction conditions can be ensured, construction quality and engineering effects can also be improved, and popularization of an ecological concrete bank protection technology is facilitated.

Description

technical field [0001] The invention belongs to the technical field of concrete revetment, and in particular relates to a method for detecting the reflectivity of planting concrete. Background technique [0002] Sediment deposits, the river bed rises, and the lower reaches of the Yellow River gradually become an above-ground river. For safety reasons, people continue to build embankments to contain the water. However, the erosion of the bank slope by the water flow often causes the embankment to collapse, and the erosion of the bank slope by the heavy rainfall often leads to soil erosion on the bank slope. In this regard, people have to take measures to harden the embankment to protect the safety of the embankment. The traditional concrete revetment engineering technology mainly considers the anti-scour of the river and the stability of the bank slope, and seldom considers the ecological environment factors. The construction methods adopted are one is cast-in-place concret...
