Embodiment 1

[0039] Such as image 3 As shown, the large-scale filling bag embankment technology of filling the embankment with dredged soil includes the following steps:

[0040] ⑴. Design and calculate the depth and spacing of the plastic drainage boards on the soft soil foundation under the embankment, complete the construction of the drainage boards and install the monitoring facilities in the soft soil foundation according to the design requirements;

[0041] ⑵. Complete the construction of each layer of sand quilt layer and soft soil row;

[0042] ⑶. Calculate the size and quantity of the required filling bags according to the design and use the polyester woven fabrics required by the design to process large filling bags for standby;

[0043] ⑷. Install dredged soil filling equipment, including silos (pools) and mud pumps, mud pumps, thick slurry pumps, and rigid feed pipelines for interconnection and installation, commissioning and trial operation. The connection of dredged soi...

Embodiment 2

[0053] It is basically the same as in Example 1, except that the filter pipe under the dredged soil filling bag is changed to a Φ76mm water-permeable corrugated hose, and the four-way and three-way connections between the main pipe and the filter pipe are U-PVC four-way and three-way.

Embodiment 3

[0055] It is basically the same as Example 1, except that according to the difference in clay content of the dredged soil, the embankment structure of one layer of sand-filled bags and two layers of dredged soil-filled bags is used instead of soil (bags) and sand (bags) alternately. The structure type of the embankment body with layers, or the structure type of the embankment body with all dredged soil filling bags.

Abstract

The invention provides a large-sized filling bag embanking method and equipment for filling an embankment by using dredged soil. The method comprises the following steps: (1) designing the depths and the distances of soft soil foundation plastic water drainage plates under the embankment, finishing the construction of the water drainage plates, and mounting monitoring facilities in the soft soil foundation; (2) finishing one layer construction of a sand quilt layer and a soft soil row; (3) processing large-sized filling bags for future use for by using polyester woven fabric; (4) mounting dredged soil filling equipment; (5) mounting an evacuating device; (6) laying an evacuating water drainage pipe network; (7) laying the filling bags and carrying out filling construction; (8) mounting an embankment surface sealing system; (9) opening an evacuating system to accelerate drainage consolidation of a dredged soil filling body and simultaneously developing relevant monitoring and detecting works; and (10) finishing an open sea side protective surface structure and an inland sea side protective slope structure in time by using the full embankment body rising process so as to reinforce the protection of the embankment body. The equipment used by the method provided by the invention is filling equipment for the dredger fill filling bags. According to the invention, the embankment building cost is reduced, the environment is protected, the stability of the embankment is guaranteed, and the clay particle content of the filling body is 10%.

Description

technical field [0001] The invention relates to a large-scale filling bag embankment embankment method using dredging filling soil for embankment, and filling equipment for the dredging filling soil filling bag used in the method. Supported by the National High-tech Research and Development Program (863 Program) (project number: 2012AA112509). Background technique [0002] At present, the dikes and breakwaters in sea reclamation projects and waterway construction projects are generally carried out by riprap, blasting, or large-scale filling bags filled with sand. Using riprap and blasting will require Large-scale mining of rocks will cause serious damage to the regional environment and will also consume a large amount of resources. It seriously deviates from the resource-saving and environmental-protective economic development mode in my country's current economic development mode. Large-scale filling bags filled with sand are used. The embankment technology will also consume...
