Problems solved by technology

However, the soil samples suitable for the traditional consolidation instrument or combined consolidation and infiltration instrument are generally solid soft clay formed by long-term deposition or soft clay with low surface water content after foundation treatment. The ultra-soft soil in the deep layer of the field is not suitable (both have the characteristics of high water content, high compressibility and poor permeability, and have obvious large-strain consolidation characteristics under load)
[0005] Based on the above problems, the patent CN209043771U discloses a soil penetration consolidation device with a water chamber, which can perform conventional penetration tests, penetration tests during consolidation or consolidation tests on ultra-soft soil samples, but the device is still The pressure method of the traditional consolidation instrument is adopted (the sample is pressed by the loading plate). For ultra-soft soil (flowing mud and floating mud in silty soil), if the sealing between the loading plate and the side wall is poor It is easy to cause the sample to overflow. If the seal between the two is too good, friction will be generated and the test results will be affected. As far as data collection is concerned, artificial reading and recording are used, and computer control and collection are not realized, and the degree of digitization is low.

Abstract

The invention belongs to the related technical field of treatment of sludge slurry with ultrahigh water content. The full-automatic hydraulic permeation consolidation device comprises a water pressurecontrol assembly, a permeation consolidation assembly, a measuring assembly and a data acquisition assembly, the water pressure control assembly is connected with the permeation consolidation assembly, and the measuring assembly is arranged on the permeation consolidation assembly and connected with the data acquisition assembly; the consolidation device is used for realizing drainage consolidation of a soil body through pushing and friction dragging effects of seepage force of high-pressure water on a soil sample; the water pressure control assembly is used for controlling the seepage force,and the data acquisition assembly is used for acquiring the pore pressure at each depth of a soil sample in the seepage consolidation assembly, the displacement at each time and the drainage rate inreal time so as to obtain the seepage coefficients of different stages. According to the invention, the filter pressing benefit is improved, real-time and automatic acquisition of test data is realized, large errors caused by manual reading are avoided, and the test data is accurate and reliable.

Description

technical field [0001] The invention belongs to the related technical field of ultra-high water content sludge treatment, and more specifically relates to a fully automatic water conservancy seepage consolidation device. Background technique [0002] With the vigorous advancement of the urban process and the construction of ecological civilization, engineering projects such as new construction and widening of port channels and lake dredging have also been carried out one after another. The dredged silt generated by this is as huge as billions of cubic meters every year. There will also be a large amount of engineering mud that has nowhere to be placed in construction (hereinafter, dredging mud and engineering mud are collectively referred to as ultra-high moisture content slurry), and the terminal disposal of huge amounts of ultra-high moisture content slurry has been plagued by engineering circles. At present, the following methods are mainly used for the treatment of ultra...
