Abstract

The invention discloses a construction process for the reclamation by the hydraulic filling of silt and a device thereof. The device comprises a solidification treatment system A and a paving system B for improved slurry, wherein the A comprises a pumping device, an impurity screening device, a solidification agent storage device, a solidification agent conveying device, a compressed air conveying device and a mixed slurry stirring and conveying device; the B comprises a connecting pipe section, a hose or belt conveyer and a bearing and moving device. The construction flow comprises the following steps of: (1) filling the silt slurry into a filling region or sedimentation tank so as to form a stacked layer of thick silt slurry; (2) pumping the thick silt slurry with the pumping device, conveying the solidification agent into the thick silt slurry at the same time, and mixing the thick silt slurry and the solidification agent in a pipe in front of or behind a pump so as to form the mixed slurry; (3) conveying the mixed slurry to the stirring and conveying device to form the improved slurry; (4) conveying the improved slurry out to the paving system B through the connecting pipe section; and (5) laying the improved slurry to specified thickness by the paving system B. The device is characterized by fast, high-efficiency, simple and convenient operation.

Description

Technical field

[0001] The invention relates to a construction technology and a device for creating land by dredging silt, and belongs to the technical field of civil engineering foundation treatment. Background technique

[0002] In recent years, my country’s coastal areas, such as the Bohai Bay area, the Yangtze River Delta, the Pearl River Delta, and the Beibu Gulf, are rapidly advancing the reclamation project from the sea. Since 2005, the coastal area of ​​China has been reclaiming land from the sea every year over 100 square kilometers. The area of ​​reclaimed land in 2009 has reached 150 square kilometers. At present, most of my country's land reclamation projects use the dredging silt land reclamation method, that is, the submarine silt is blown into the enclosure, and the silt is transformed into a foundation with a certain bearing capacity after a certain treatment.

[0003] At present, the main method for treating these dredging silt is to use the drainage consolidation ...
