Problems solved by technology
[0003] There are a large number of multi-layer soil foundations distributed in the coastal areas of our country, and the typical ones are soft soil foundations lying below the hard shell layer. The current compression consolidation test can only test the single-layer soil, and cannot test the multi-layer foundation soil. There are certain deficiencies in the composite test: the existing indoor compression-consolidation tester is limited to the compression-consolidation test of single-layer soil, and for the compression-consolidation test of multi-layer soil, it is often necessary to separate each layer of soil for a separate compression-consolidation test so that To obtain the compression consolidation parameters, it is impossible to test the compression deformation of multi-layer soil, and it is impossible to simulate the interaction of compression deformation between layers of soil. The purpose of the instrument is single, and the traditional compression consolidation instrument must be read at intervals, and the manual reading is cumbersome , less efficient
[0004] To sum up, the existing traditional compression consolidation instrument has a relatively single purpose, and the influence of human factors is relatively large, so it is impossible to simulate the mutual seepage effect between multi-layer foundations

Embodiment Construction
[0027] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] Such as figure 1 As shown, a visual soil sample compression consolidation test system according to the present invention includes a pressure rod 1, a transparent plexiglass bucket 2, a water-permeable pressure plate 3, a soil sample 4, a water-permeable stone 5, and a dial indicator 6. The camera 7 and the fixing part 8. The soil sample 4 is put into the transparent plexiglass barrel 2 as the test soil body. In the transparent plexiglass barrel 2, the load is transmitted to the surface of the soil body by the pressure rod 1, and the upper part of the soil body is evenly applied by the smooth water-permeable pressure bearing plate 3. On the surface of the soil, the lower part of the soil is a permeable stone 5, and at the same time, a dial gauge 6 is arranged on the upper surface of the permeable pressure bearing plate ...

The invention discloses a visualized soil body sample compression consolidation test system. The visualized soil body sample compression consolidation test system comprises a multilayer soil compression chamber, a pressurizing device, a dial indicator and a video camera, and a compression chamber body is a transparent organic glass barrel and is internally composed of a soil sample, a water-permeable pressure bearing plate and water-permeable stone. The transparent compression chamber in the visualized soil body sample compression consolidation test system enables compression deformation of the soil sample under the load effect to be visualized, the soil body compression consolidation process can be monitored through the video camera for digital processing, and thus the compression amountis obtained. The visualized soil body sample compression consolidation test system is convenient to operate and high in efficiency, the compression process of a multiplayer soil foundation on site canbe simulated flexibly, thus the multiplayer soil compression consolidation process is obtained, the whole process is visualized, and automatic reading is conducted to record the compression consolidation process and result.
Description
technical field [0001] The invention belongs to the technical field of compression consolidation tests, in particular to a visual soil sample compression consolidation test system. Background technique [0002] Now in general foundation treatment design and related foundation consolidation research, it is necessary to obtain the compression and consolidation parameters of the foundation soil, so that the foundation treatment design can be carried out, and the compression and consolidation amount of the foundation can be calculated. Such parameters often need to be obtained through compression consolidation tests. [0003] There are a large number of multi-layer soil foundations distributed in the coastal areas of our country, and the typical ones are soft soil foundations lying below the hard shell layer. The current compression consolidation test can only test the single-layer soil, and cannot test the multi-layer foundation soil. There are certain deficiencies in the comp...
