Problems solved by technology

[0002] With the rapid development of the national economy, the amount of geotechnical engineering construction has doubled, and a large amount of waste mud has been generated during the construction process. Because the engineering waste slurry is difficult to be treated centrally, it has caused great pollution to the environment. The current The treatment method is to use tank trucks to transport the on-site muddy water to the suburban garbage dump, and let it dry naturally. This treatment method is primitive and backward, and has caused many problems. First, it needs to occupy land resources, and second, the transportation cost is high. Therefore, it is necessary to separate the mud and water from the mud on site to make the sludge settle quickly, facilitate the discharge of the supernatant and the drying treatment of the soil, and provide convenience for engineering construction
