Embodiment 1

[0044] Application of the method of the present invention in land reclamation

[0045] 1. Processing and production of filling bags:

[0046] The woven bag used to make the filling bag is made of polypropylene and woven needle-punched composite geotextile, with a weight of 200g / m 2 , the warp and weft yarn is 15 wires / inch, the thickness is 0.8mm, the tensile strength in the warp and weft direction is 1000N / 5cm, and the equivalent aperture is O 90 is 0.3mm, and the permeability coefficient is 10.0×10 -3 cm / s.

[0047] The filling bag is processed into a rectangular shape, with a length of 10-50 meters and a width of 4-8 meters. It is manufactured according to the embankment construction drawing design drawings during processing. At the same time, combined with the control of construction settlement and increasing the shrinkage rate by 3%, according to the conventional method, the tension bars are set along the length direction to control the thickness of the filling bag. Th...

Abstract

The invention discloses a method for achieving slurry water separation and solidification of filling soil by utilizing a filling bag and a construction device, and provides the method and the device for achieving slurry water separation and solidification of filling soil by utilizing the filling bag, wherein silty soil or the mixture of silty soil and mucky soil is used as filling soil. A separating agent, a curing agent and filling soil are mixed completely through stirring, and then are filled in the filling bag; and separated water is drained out of the filling bag, and filling soil is deposited and solidified. The separating agent is a polluted water treatment agent STIR-S, and the curing agent is agglutinant STIR-Y for sewage disposal. The method leads slurry and water in a filling sand bag to be separated rapidly through rational choice and scientific ratio of the separating agent and the curing agent; water can be drained rapidly through the osmosis of a woven bag; and meanwhile, the curing agent added in filling soil can promote the soil agglomeration, can accelerate the consolidation of a soil body, can reduce the construction period by about 40 percent, and the method and the device are mainly suitable for the sand bag filling engineering for protection banks, reinforcing dams, protection slopes, dams and breakwater in harbors, river channels and the like.

Description

technical field [0001] The invention relates to the field of port waterway engineering, in particular to a method and a construction device for realizing the separation and solidification of filling soil, mud and water by using a filling bag. Background technique [0002] With the rapid growth of my country's economy, my country's coastal ports have ushered in a new development period, and large-scale land reclamation projects and coastal zone development projects are booming. At present, block stone materials and filling sand are widely used for land reclamation and embankment. However, with the large-scale use of block stone materials and filling sand materials, there has been a tension in the relationship between supply and demand. Moreover, in order to protect resources, mining is also restricted. [0003] Currently, Panjin in Liaoning, Caofeidian in Hebei, Huanghua in Hebei, Binzhou in Shandong, Dongying, Weifang and coastal areas in Jiangsu are all building land from...
