Problems solved by technology

Traditional silt drainage bodies generally use plastic drainage boards. However, plastic drainage boards have the disadvantages of being difficult to degrade and pollute the environment, and are not suitable for storage yards that are used for farming after drainage consolidation treatment.

Embodiment

[0029] Specifically, the application provides a method for forming ecological drainage and rapid soilization of deep silt in the dredged silt of the stockyard, comprising the following steps:

[0030] The first step is to make the filler 5, mix and stir the nutrient soil, decomposed dung and perlite to form the nutrient soil, and add reed seeds or rhizomes to the nutrient soil during the stirring process;

[0031] What needs to be explained here is that nutrient soil can be purchased directly in the market, or it can be configured by the user. The only requirement for its performance is that it cannot be soil with too fine particles, because during the entire drainage process, it needs Drainage channels are formed in the dredged silt. If the particles of the nutrient soil are too fine, it will affect its air permeability and drainage performance. Therefore, the application provides a preferred embodiment. The field soil accounts for 50%-60% of the total mass of the filler 5, an...

Abstract

The invention relates to a method for forming ecological drainage in dredged sludge of a storage yard and rapidly earthing deep sludge. A ventilating pipeline is arranged in a geotextile bag to provide oxygen and illumination suitable for plants to grow in the deep sludge of the storage yard, ecological drainage is combined with growth habits of rhizome type wetland plants such as reeds, a drainage channel is formed by rhizomes of the plants in the growth process, meanwhile, the original drainage channel is widened through growth of the plants, absorption of water in the sludge of the storageyard is accelerated, meanwhile, organic matter secreted by the plants promotes activity of the sludge, and earthing of the sludge of the storage yard is accelerated.

Description

technical field [0001] The invention relates to a method for forming ecological drainage in the dredged silt of a stockyard and a method for rapid soilization of the deep silt, belonging to the field of dredged mud drainage. Background technique [0002] A large amount of dredging silt will be produced in the river dredging in our country every year, and stockyard static is a common method to deal with river dredging silt at present. Due to the extremely high water content of the dredged silt, it has been placed in the yard for a long time, occupying a large amount of land resources. [0003] At present, drainage consolidation technology is a common method for sludge foundation treatment. In this method, drainage bodies need to be drilled in the sludge to reduce the drainage distance, and combined with other loading methods, such as well point dewatering technology, surcharge preloading, vacuum Preloading, vacuum-surcharge combined preloading, etc., to remove the water in t...
