Problems solved by technology

[0002] The traditional joint treatment method of sea reclamation generally adopts the vacuum preloading drainage method. By inputting mud into the mud pool, inserting the drainage board, and covering the vacuum coating, the water is discharged outwards under the suction of the vacuum pump, but the drainage board first What is in contact with is silt. When water enters the drainage board, it will also take away the soil. When the soil particles are small, the soil can easily enter the drainage board. The problem of blocking the drainage board can not be solved.
In addition, the soil and water in ordinary sludge are mixed together, resulting in low drainage rate during vacuum preloading treatment.

Abstract

The invention discloses a combined treatment method for reclaiming land from the sea. The combined treatment method comprises following steps: A, extracting slurries and injecting slurries with flocculating agents and / or lime; B, inputting slurries into a stirrer for uniform stirring; C, inputting uniformly-mixed slurries into a vacuum pre-loading slurry pool; C, equipping the vacuum pre-loading slurry pool with vertical drainage boards, connecting upper ends of the vertical drainage boards to an drainage pipeline which is connected with the outside, covering the top of soil in the vacuum pre-loading slurry pool and the drainage pipeline with sealing cloth, adopting a sealing structure and soil sealing for the edge of the sealing cloth, connecting a vacuum pump with the drainage pipeline for extracting water in soil. The combined treatment method for reclaiming land from the sea has following beneficial effects: 1, the drainage boards are not easily blocked; 2, soil bearing capacity after processing is increased and sedimentation is reduced.

Description

technical field [0001] The invention relates to a combined treatment method for sea reclamation and land reclamation. Background technique [0002] The traditional joint treatment method of sea reclamation generally adopts the vacuum preloading drainage method. By inputting mud into the mud pool, inserting the drainage board, and covering the vacuum coating, the water is discharged outwards under the suction of the vacuum pump, but the drainage board first What is in contact with is silt, and when water enters the drainage board, it will also take away the soil. When the soil particles are small, the soil can easily enter the drainage board, and the problem of blocking the drainage board can not be solved. In addition, the soil and water in ordinary sludge are mixed together, resulting in low drainage rate during vacuum preloading treatment. Contents of the invention [0003] In view of the deficiencies in the background technology, the technical problem to be solved by t...
