Description
Technical field
The utility model relates to the mensuration of high-moisture percentage dredging silt flowing property in hydraulic engineering and Geotechnical Engineering, specifically provides a kind of device adopting truncated cone pipe to measure mud mobility.
Background technology
Along with the increasing of China's hydraulic engineering construction and water environment treatment engineering, the dredging work amount cumulative year after year of the bed muds such as river, lake, ocean.Such as, total accumulation of bottom mud in Taihu Lake is 19.12 hundred million m
3, wherein seriously polluted and need dredging total amount more than 3,500 ten thousand m
3; Jiangsu Province has the Eleventh Five-Year Plan period furnished funds for 5,000,000,000 yuan, and dredged the whole province more than 8000 main river course, total dredging silt amount reaches 600,000,000 m
3; The Dredged marerial that China abandons every year in ocean is all at 100,000,000 m
3above.The issue of in April, 2015 " ten, water " policy, will start the new round climax of bed mud desilting engineering in water environment treatment.
Mud is defined as and deposits in flowing water environment at hydrostatic or slowly in soil mechanics, and is formed through biological chemistry action, its natural moisture content is greater than liquid limit, natural void ratio be more than or equal to 1.5 cohesive soil.Dredging refer to through waterpower to dredge etc. technology will deposition bed mud hydraulic reclamation to the process in stockyard, the Sediment Dredging of China adopts cutter suction dredger usually, by steam piano and mud conveying pipeline by mud hydraulic reclamation to delimitation stockyard, this method mud solid-to-liquid ratio of dredging out only about 1/5, concentration is less than 20%, there is the distinguishing feature that water percentage is high, clay content is high, compressibility is high and undrained strength is low, cause certainly the flump silt process of mud in stockyard slow, be difficult to form the closely knit soil body.
Because the water percentage of dredging silt is high, soil mechanical properties are poor, are mainly treated to master by land hydraulic reclamation or ocean throwing for a long time, not only waste soil body resource but also may cause environmental pollution.In recent years, the resource utilization method development of mud rapidly, such as, sintered brickmaking, plate compression, sludge solidification process etc., and wherein, solidification process is because treatment effeciency is high, be applicable to the process of extensive mud.
Be no matter the methods such as the Dredging Process of mud, or the solidification process of mud, the mobility of mud self is all the important step determining dredging and process.Such as, for the Dredging Process of mud, the long-term bed mud in river lake bottom deposition is after the disturbance of reamer head, bed mud is extracted in mud conveying pipeline by steam piano with the form of mud, generally for that mud is flowed in the duct is smooth and easy, and the dredging concentration of mud and water percentage need to control within the specific limits, concentration is too low, mud conveying pipeline easily blocks, and concentration is too high, and dredging efficiency is low.However, the technician of current China dredging work circle only can determine with experience directly perceived some key parameters dredging link, makes the problem that often there will be mud conveying pipeline blocking in dredging work, has a strong impact on dredging work progress.Equally, for sludge solidification engineering, be no matter the sludge solidification treatment method of the employing solidifying equipment of current comparative maturity, the mud flow automation disposal route still just begun one's study, the mobility of mud is all the important factor in order determining sludge solidification effect.And about the mensuration of mud mobility, country and industry all do not have the standard of special mensuration mud mobility, this also just makes engineering technical personnel have less understanding, and can comply with without specification, causes the generation of engineering problem.
Utility model content
