Ventilating vacuum fast mud-water separating method for high-water content mud accumulation dredging yard

A technology for dredging silt and separating mud and water, which is applied in the fields of waterways, water conservancy projects and ports. It can solve the problems of large amount of dredged silt, occupying a lot of land, and taking a long time, so as to reduce the water content of silt, reduce the occupied area, and lighten the effect of difficulty

Embodiment Construction

[0015] As shown in Figure 1 and Figure 2, the specific steps and contents of the construction are as follows:

[0016] 1. Construct a spatial drainage system:

[0017] 1) Processing materials: do a good job of perforating the water filter pipe, covering the water filter material and cutting off the plastic drainage board at the material processing site;

[0018] 2) Laying of horizontal, horizontal and vertical drainage channels: first set up a connected horizontal and horizontal water filtration and drainage network 2, horizontal and vertical drainage pipes 3 on the foundation in the cofferdam 1, and set up a vacuum device 5 and a vacuum device on the cofferdam 1. The venting device 13, the horizontal and vertical drainage pipe 3 is connected to the vacuuming device 5 through the water pipe 4, and is connected to the venting device 13 through the air pipe 12, and the vertical plastic drainage plate 6 is connected side by side on the horizontal and horizontal water filtering and dr...

Abstract

The invention discloses an air permeable vacuum fast mud-water separation method of the dredged sludge storage yard with high water content, which relates to a water content fast reducing method of the dredged sludge with high water content and high clay content produced in the ports, the sea-routes and the hydraulic engineering. Through a vacuum extractor and a venting device, vacuum negative pressure in a space drainage system in a cofferdam storage yard is regulated, which can effectively solve the sludge plugging problem of the filtering and drainage system, cause the water content of the dredged sludge to be fast reduced, increase the sludge dredging amount of the cofferdam storage yard with the same capacity and reduce the land occupying area; meanwhile, the fast reducing of water content of the sludge can lighten the difficulty of subsequent processing of the sludge in the storage yard and shorten the construction period. With simple technique, low cost and obvious mud-water separation effect, the method is applied to the construction practice.

Description

Technical field [0001] The invention is a method for quickly separating the water from the high-water content dredged silt yard produced in the construction of water conservancy, port wharf, and waterway engineering, and is suitable for large-area comprehensive disposal projects of low-concentration dredged silt, and belongs to ports, waterways and water conservancy projects Technical field. Background technique [0002] With the development of the construction of ports, waterways and water conservancy, a large amount of dredged silt will inevitably be generated in the dredging and widening of various waterways and rivers, as well as in the construction and expansion of ports. According to incomplete statistics, my country’s annual abandonment of dredged silt The dredged silt reaches more than 100 million cubic meters, and the amount of dredged silt treatment is very considerable. Taking the first phase of the Jiangsu section of the East Route of the South-to-North Water Transfer...
