Abstract

This is a quick damming method suitable for yielding soil treatment composed by several layers of sullage and sand. At building, a layer of sullage is dumped then a layer of sand. Sand will sink into sullage by gravity to increase sullage penetrability. The procedure is repeated till reach the designed height. Put loading, like water bag, to the dam top to move out water and solidify.

Description

technical field

[0001] The invention relates to a sludge solidification method, which is suitable for the treatment of soft ground and belongs to the technical field of civil engineering. Background technique

[0002] With the rapid development of my country's economy, construction projects such as port engineering, waterway engineering, and water conservancy engineering have increased rapidly. In the dredging process of various waterways and in the construction and expansion of ports, a large amount of dredged soil is usually produced. According to incomplete statistics, the discarded dredged silt in my country reaches 100 million m3 every year. 3 Above, the engineering quantity of dredging silt treatment is very considerable. Currently, there are two methods of silt treatment that are often used. One is to throw the silt into the sea, and the other is to fill the land with cofferdams near the shore.

[0003] The land reclamation method of the cofferdam near the shore is ...
