Description

Technical Field

[0001] The present invention belongs to the technical field related to ultra-high water content sludge treatment, and more specifically, relates to a fully automatic hydraulic penetration consolidation device. Background Art

[0002] With the vigorous promotion of urban development and ecological civilization construction, the construction and widening of port channels, lake dredging and other engineering projects have been carried out one after another. The dredged sludge generated each year reaches billions of cubic meters. At the same time, due to engineering construction, there will be a large amount of engineering mud with nowhere to be placed (hereinafter referred to as ultra-high water content mud slurry). The terminal disposal problem of huge ultra-high water content mud slurry has always troubled the engineering community. At present, the following methods are mainly used to treat ultra-high water content mud slurry:

[0003] 1. The plate-and-frame compressor is used to dehydrate and reduce the volume of ultra-high water content sludge. In order to improve the dehydration efficiency of the sludge and seek ways to recycle it, other reagents (such as curing agents, flocculants, etc.) are often added to the sludge. The changes in the properties of the sludge by the reagents will inevitably lead to adjustments in the filter press parameters. If the filter press parameters are not set properly, it may shorten the life of the filter press equipment, reduce the filter press efficiency, increase the filter press cost, and other problems. However, there is currently no suitable test device for exploring the filter press dehydration process of such mixed sludge slurries, thereby providing an effective basis for optimizing the filter press parameters.

[0004] 2. The ultra-high water content slurry is directly transported to the storage yard for stacking, so that it can be deposited and consolidated by its own weight, and then further treated by foundation treatment methods (vacuum / loading preloading method, etc.) to develop it into usable land. For engineering construction on such foundations, the settlement problem cannot be avoided. At present, the settlement and deformation law of soft soil foundations is often studied with the help of indoor consolidation tests. The consolidation instrument is an important test instrument in such geotechnical tests. In order to better study the consolidation mechanism of soft soil, in recent years, many scholars have developed a consolidation-permeability combined instrument that can perform both consolidation tests and permeability tests. However, the soil samples suitable for traditional consolidation instruments or consolidation-permeability combined instruments are generally solid soft clays formed by long-term deposition or soft clays with low surface water content after foundation treatment methods. They are not suitable for ultra-high water content slurry or ultra-soft soils deep in the storage yard (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, patent CN209043771U discloses a soil permeation consolidation device with a water cavity, which can perform conventional permeability tests, permeability tests during consolidation, or consolidation tests on super-soft soil samples. However, the device still uses the pressurization method of the traditional consolidation instrument (pressurizing the sample through the loading plate). For super-soft soil (fluid 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 sealing between the two is too good, friction will be generated, thereby affecting the test results. As for data collection, manual reading and recording are used, and computer control and collection are not realized, and the degree of digitization is low. Summary of the invention

[0006] In view of the above defects or improvement needs of the prior art, the present invention provides a fully automatic hydraulic penetration consolidation device, which can simulate the hydraulic penetration consolidation process of mud on the filter membrane surface of a plate and frame filter press under the action of feed pressure, thereby optimizing filter frame thickness, filtration pressure, filtration time and other filter pressing parameters, improving filter pressing efficiency, and proposing a new pressurization method (using the penetration force to push the soil skeleton and the friction drag effect to achieve drainage consolidation of the sample), eliminating the overflow phenomenon or friction between the loading plate (cover) and the side wall, and can intuitively monitor the deposition and consolidation process of high-water content sludge slurry, realize penetration and consolidation tests under various levels of penetration pressure, automatically and in real time collect and store test data, obtain the settlement change law of the sample during the consolidation process, water flow rate, drainage and permeability coefficient, etc., and can measure the pore pressure of soil samples at different heights, the change of pore water pressure of each layer of soil samples (for ultra-soft soil with low water content), and provide a testable device for the large strain consolidation theory with pore water pressure as a variable.

[0044] The working process of the hydraulic penetration consolidation device is as follows:

[0045] Step 1: Turn on the computer 21 and switch to data acquisition and water pressure control of liquid level.

[0046] Step 2: Open the first water inlet valve 3, and close it after the water in the high-pressure water storage tank 2 is full. Open the aluminum alloy upper cover 11 and the water stop valve 16, and inject low-pressure water into the organic glass pressure chamber 12 until the filter cloth 25 is just submerged.
