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 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.

[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 t...

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 device and method for detecting the anti-seepage performance of a granular material. The detection device comprises an outer cylinder and an inner cylinder inserted in the outer cylinder. The bottom of the inner cylinder is located in the outer cylinder, the bottom of the inner cylinder and the bottom of the outer cylinder are arranged at intervals and provided with water permeable holes respectively, the space between the outer cylinder and the inner cylinder is used for restraining to-be-detected particle materials naturally accumulated in the space into a cylindrical container shape, and the top of the inner cylinder is used for water inflow. Compared with the prior art, the provided device has the following beneficial effects: the inner cylinder and the outercylinder are combined; the to-be-detected granular material naturally accumulated in the gap between the inner and outer cylinders is retrained into a cylindrical container; water is added in the inner cylinder, equivalently, water is added into the particle container; the liquid is isolated from the inner wall of the outer cylinder by the to-be-detected particles, so that the side wall effect generated in the detection process is eliminated, water is prevented from leaking from a gap between the to-be-detected particle material and the detection device, the detection condition of the anti-seepage performance is closer to the actual condition of the particle material in a natural accumulation state, and the detection result is 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 ...
