On the other hand, as described above, the solidifying agent adding device 300 is connected to a line for supplying compressed air to the ejector 260 mounted in the middle of the discharge pipe 250, and supplies the solidifying agent. It is composed of a silo 310 and a solidifying agent supply device 320. The solidifying agent silo 310 contains powder such as cement or cement-based solidifying agent, and the solidifying agent supply device 320 is, for example, a rotary feeder, a table feeder, a piston feeder or the like. Adopting a feeder, flow meter 2
The drive device is controlled according to the actual flow rate of the soft mud measured in 30, and the supply amount is adjusted. The solidifying agent may be a powder as it is or a slurry with water added, and the selection is determined by the degree of mixing depending on the soil. However,
Since it is more economical to use the powder as it is, use it as it is if there is no significant difference. Therefore, the solidifying agent may be supplied as a powder, but depending on the soil quality, a slurry with water added is desirable for uniform mixing with the soft mud. In the case of slurry-like addition, the solidifying agent supply device 320 is provided with a storage tank equipped with a mixer (mixing stirrer), and a water supply line is connected thereto to make powdery solidifying agent into slurry and then discharge it. The solidifying agent is added at a ratio of 50 to 200 kg (usually 100 kg) to 1 m 3 of soft mud. In the present invention,
As described above, the slurry in which the powder or the water is added and mixed by the amount corresponding to the flow rate of the softening agent is supplied from the compressed air supply line, which is a means for pumping the softening agent, to the softened matter which is pneumatically conveyed through the discharge pipe 250. Therefore, it is mixed evenly and moderately in the soft mud during plug transportation, and after reaching a remote destination, it solidifies more than necessary strength after a certain period of time (usually 2 to 7 days). That is, the addition amount of the solidifying agent is determined depending on the type of mud soil and how many kgf / cm 2 of strength the material should have after a certain number of days. As a matter of course, the larger the added amount, the faster and harder the solidified. As described above, since the uniform mixing of the soft mud and the solidifying agent in the present invention is efficiently performed during the plug transportation in the discharge pipe, the length of the discharge pipe 250 is required to be at least 50 m. It is also possible to directly equip a dredger with the device of the present invention, dredge soft mud such as sludge on the seabed, perform a solidification treatment, and transport it to a distant destination.
