Abstract

The invention discloses a method for processing and recycling slurry shield muck. According to the method, slurry is coarsely screened, primarily swirled to remove sand and swirled for the second time to remove mud; then the processed over-rich slurry is pressed for filtering, so that the muck taken out along with a slurry recycling system of a slurry shield can be graded and separated more finely, thus the purpose of optimizing the performance of the shield recycling slurry can be achieved; meanwhile, due to the gradation and separation of the shield muck, particles of different types and different properties are recycled and reused specifically; useful components of the shield muck are reused in the scene shield construction, so that the material purchase cost can be saved; outward transport of the waste muck and outward drain of wastewater can be reduced; the construction cost can be saved; the construction environment can be effectively protected.

Description

technical field [0001] The invention relates to a construction method for processing and recycling muddy water shield dregs. Background technique [0002] In many mud-water shield constructions, the treatment of mud-water shield slag is only separated by simple coarse particle screening equipment. The slag screened in this way has high mud content, high water content, loose structure, and a large amount of discarded slurry. Moreover, the grading of the slag particles separated by this treatment method is unclear, making it impossible to recycle valuable components in the slag. For such muck with high mud content and high water content, it is currently transported by a large number of vehicles to a special muck dump for storage. A small amount of leakage is unavoidable during transportation, and the accompanying mud will cause certain pollution to the environment after escaping, and even the mud will cause dust and reduce air quality after drying. In addition, a large amou...
