Laboratory investigation of permeability property of natural gravels with different particle sizes under different laying conditions
The seepage properties of natural gravel are one of the problems to be considered in seepage project designs. In this paper, the seepage properties of the natural gravel with particle sizes of 5, 20 and 60 mm were investigated under different laying conditions. The effect of the particle size, laying depth, bulk density and pressurized head on the seepage properties of the natural gravel was analyzed by using the combined methods of theoretical analysis with physical model test. The results showed that the seepage flow in the natural gravel was non-laminar flow in the test conditions described in this paper. Meanwhile, the relationship between particle size, laying depth, bulk density, pressurized heads and seepage property was established. The seepage discharge increased with the increase of the pressurized head and particle size, and decreased with the increasing of laying depth and bulk density. The critical laying depth and bulk density can be obtained when the seepage discharge becomes zero. The empirical formula of the seepage discharge of natural gravel with different particle sizes, laying depths, bulk densities and pressurized heads was obtained with the method of nonlinear regression, which can be expressed as: . The empirical formula was experimentally validated. The maximum relative error did not exceed 6.73%, proving that the empirical formula of the seepage discharge of natural gravel was rational. The results can provide an important reference to further studying the seepage properties of macropore media, and form a theoretical basis for applying the natural gravel in the seepage projects.- 1 January 2021

Study on the velocity characteristics of spiral flow in pipeline with different numbers of guide bars installed on the surface of the piped vehicle body
The piped hydraulic transportation of tube-contained raw material is a new low-carbon and environmental protection technique for transporting materials. The velocity characteristics of the spiral flow in the pipe with different numbers of guide bars installed on the surface of the piped vehicle body during piped hydraulic transportation of tube-contained raw material were studied by the theoretical analysis and model test. In the test, the numbers of guide bars placed on the surface of the piped vehicle body was respectively 3, 4, 5, and 6, and the studied sections were the section of the piped vehicle body and its rear section, and the flow discharge was 40 m3/h. The results showed that as the number of guide bars increased, the axial velocity of the section of the piped vehicle body increased gradually, while the axial velocity of the rear section of the piped vehicle reduced first and then increased. The section circumferential and radial flow velocity of the piped vehicle body and its rear section both increased first and then reduced. When the number of guide bars installed on the surface of the piped vehicle body was 4, the section circumferential flow velocity of the piped vehicle body and its rear section reached the maximum value, and their distributions were relatively uniform. The results offer theoretical basis so that we can optimize the structure of the piped vehicle and further popularize the piped hydraulic transportation technique of tube-contained raw material.
