Embodiment Construction

[0028] The present invention is described in further detail below in conjunction with accompanying drawing:

[0029] see figure 1 , the present invention provides a fitting adaptive soil penetration test device, which is sequentially connected with a water inlet 1, an upstream buffer zone 2, an upstream sample chamber 4, a downstream sample chamber 7, a downstream buffer zone 9 and a water outlet 10. . The upstream buffer zone 2 and the upstream sample chamber 4 are separated by an upstream permeable screen 3, the downstream sample chamber 7 and the downstream buffer zone 9 are separated by a downstream permeable screen 8, and the upstream buffer zone 2 and the downstream buffer zone 9 are filled with aggregates, and the mesh apertures of the upstream permeable screen 3 and the downstream permeable screen 8 are smaller than the particle size of the aggregate; the upstream sample chamber 4 and the downstream sample chamber 7 are detachably connected.

[0030] Here, the upstre...

Abstract

The invention discloses a fitting self-adaption soil body permeability test apparatus and a use method for same. The test apparatus, in a successively communicated manner, is provided with a water inlet, an upstream buffer zone, an upstream sample chamber, a downstream sample chamber, a downstream buffer zone, and a water outlet. The upstream buffer zone is separated from the upstream sample chamber through an upstream water-permeable separating screen; the downstream buffer zone is separated from the downstream sample chamber through a downstream water-permeable separating screen. A skeletal material is packed in both the upstream buffer zone and the downstream buffer zone. Diameters of meshes in the upstream and the downstream water-permeable separating screens are both smaller than the granular size of the skeletal material. The upstream sample chamber is detachably connected to the downstream sample chamber. The test apparatus solves the problem that there is no test device aiming to test on damage and loss on soil bodies under permeation in the prior art, can simulate deterioration and damage on soil body samples, in different lengths, under permeation, and can improve controllability of the test.

Description

technical field [0001] The invention belongs to the fields of soil and water conservation and soil mechanics, and in particular relates to a matching and self-adaptive soil penetration test device and a using method thereof. Background technique [0002] Soil erosion is serious in the middle and upper reaches of the Yangtze River and the Yellow River. On the one hand, it is due to the increase in sediment load caused by precipitation and groundwater erosion; Serious damage and loss have brought greater challenges to the sand control work in the area. Therefore, it is very necessary to study the failure process and mode of soil under infiltration. [0003] At present, the tests on the damage and loss of soil under infiltration are immature, and there are no more targeted test methods and test equipment, and the controllability of the existing tests is poor. [0004] Therefore, how to design a device for soil penetration test that can more realistically reflect the evolution...
