Embodiment 1

[0035] A detection device for the anti-seepage performance of granular materials, such as figure 1 As shown, it includes an outer cylinder 1 and an inner cylinder 4 inserted in the outer cylinder 1. The bottom of the inner cylinder 4 is located inside the outer cylinder 1 and is spaced apart from the bottom of the outer cylinder 1. Between the outer cylinder 1 and the inner cylinder 4 The space is used to constrain the natural accumulation of the granular material to be measured in the space into a cylindrical container shape. The top of the inner cylinder 4 protrudes from the top of the outer cylinder 1 and is used for water intake. The bottoms of the inner cylinder 4 and the outer cylinder 1 are both Water permeable holes 11 are provided.

[0036] In this embodiment, preferably, the top of the inner cylinder 4 is provided with an inner cylinder top cover 6, and is connected with a water inlet pipe, and a pressure gauge 9 and a water inlet valve 10 are arranged on the water i...

Embodiment 2

[0059] A detection device for the anti-seepage performance of granular materials, such as figure 2 As shown, it includes an outer cylinder 1 and an inner cylinder 4 inserted in the outer cylinder 1. The bottom of the inner cylinder 4 is located inside the outer cylinder 1 and is spaced apart from the bottom of the outer cylinder 1. Between the outer cylinder 1 and the inner cylinder 4 The space in the space is used to constrain the natural accumulation of granular materials to be measured in the space into a cylindrical container shape. The top of the inner cylinder 4 protrudes from the top of the outer cylinder 1 and is used for water intake. The bottoms of the inner cylinder 4 and the outer cylinder 1 are both Water permeable holes 11 are provided.

[0060] In this embodiment, the top of the inner cylinder 4 is preferably open.

[0061] The detection method of the anti-seepage performance of the granular material adopts the detection device of this embodiment, and the meth...

Abstract

The invention relates to a detection device and method for the anti-seepage performance of granular materials. The detection device includes an outer cylinder and an inner cylinder inserted in the outer cylinder. The bottom of the inner cylinder is located inside the outer cylinder and is spaced apart from the bottom of the outer cylinder. Both are equipped with water-permeable holes, the space between the outer cylinder and the inner cylinder is used to constrain the natural accumulation of granular materials to be measured in the space into a cylindrical container shape, and the top of the inner cylinder is used for water intake. Compared with the prior art, the present invention constrains the granular material to be tested naturally accumulated in the gap between the inner and outer cylinders into a cylindrical container through the combination of the inner and outer cylinders, and adding water to the inner cylinder is equivalent to adding water to the particle container, and the liquid and the outer cylinder The inner wall is isolated by the particles to be tested, which eliminates the side wall effect generated during the detection process, prevents water from leaking from the gap between the granular material to be tested and the detection device, and makes the detection conditions of the anti-seepage performance closer to the natural accumulation of granular materials The actual situation, the test results are more accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of anti-seepage performance detection of granular materials, in particular to a detection device and method for anti-seepage performance of granular materials. Background technique [0002] Super-hydrophobic particles are a kind of particle materials with anti-seepage properties prepared by using quartz sand, desert sand, river sand, sea sand, tailings sand, fly ash floating beads and other granular materials as core materials. Super-hydrophobic particles have excellent waterproof performance, and have very broad application prospects in the fields of vegetation planting in sandy soil and saline-alkali land, integration of waterproof and thermal insulation of building roofs, artificial lakes and farmland water conservancy and anti-seepage, underwater plugging, and oil pollution cleaning in water areas. Therefore, how to accurately, simply and quickly detect the anti-seepage performance of granular materials ...
