Problems solved by technology

The method of determining the consolidation coefficient by indoor consolidation test is the most commonly used method, and its disadvantages are small test specimen, heavy workload, long test time, high cost and large disturbance of soil samples
Since the soil sample cannot accurately reflect the actual conditions of the construction site, the indoor test results are quite different from the actual value of the site soil, which cannot fully reflect the actual consolidation coefficient of the site soil, and cannot take into account the soil under the stress of the soil's own weight.

Embodiment Construction

[0025] Combined with the accompanying drawings of the manual, the test device for the indoor settlement column test to simulate the self-gravity deposition and consolidation process of silt soil is further explained:

[0026] The indoor settling column simulates the self-gravity deposition and consolidation process of silt soil. The test device is mainly composed of three parts: a settling column (Fig. 1), a mud mixer (Fig. 2), and a small disturbance soil sample collector (Fig. 3). The specific production and operation process of the test device of the present invention are as follows:

[0027] (1) Make the settling column (Fig. 1), make the plexiglass tube column body 1 and the reinforced base 2 respectively with plexiglass, and use an organic adhesive to cement the two to form a reliable column body and column bottom cemented connection 6. Among them, the plexiglass tube body 1 has a height of 1000mm, an inner diameter of 130mm, and a wall thickness of 10mm; the reinforced ...

Abstract

The invention discloses a testing device for simulating a warp self-weight settlement consolidation process by a settlement column indoors, comprising an organic glass tube settlement column, a slurry stirrer, a soil sample geotome and the like. The body of the settlement column is connected with a base; a paper ruler is adhered outside the tube wall of the column body; slurry suspension is injected behind the body of the organic glass tube settlement column, the slurry suspension is stirred and mixed uniformly up and down by inserting the stirrer; the opening of the column body is sealed by a rubber band after the opening of the column body is sealed by a seal membrane; the settling height of the suspension level along with time is recorded by observing the paper ruler outside the tube wall so as to study the free settling law of the warp slurry under self-weight action; and after the warp self-weight settlement consolidation process is completed, soil is taken by the geotome layer by layer, the void ratio e of soil layers with different depths is detected, the warp self-weight consolidation law is studied, and the soil body consolidation coefficient cv is calculated. The testing device has the characteristics of small floor area, convenient operation, accurate and reliable data observation, less moisture loss, small soil sample disturbance and the like, and can be applied to early test study of river channel training, harbor desilting, backfill land reclamation and other engineering.

Description

technical field [0001] The invention belongs to the interdisciplinary technical field of geotechnical engineering basic test and environmental engineering, and in particular relates to an indoor settlement column simulating test device for the self-gravity deposition and consolidation process of alluvial soil. Background technique [0002] The settlement column test is an important test device for studying the sedimentation and self-weight consolidation of river, lake and marine sedimentary soils. The settlement column test device can be used to simulate and measure the self-weight consolidation coefficient c of the sedimentation sediment mud at different concentrations v . The test results provide basic engineering parameters for river dredging and widening projects, port dredging and treatment projects, lake protection and pollution control projects, etc., and provide necessary technical support for project implementation plans and design ideas through indoor settlement co...
