ている。(Conventional technology) Traditionally, civil engineering work generates a large amount of excavated mud, a large amount of sludge is also generated from wastewater treatment equipment, etc., and dredging work for irrigation ponds etc. generates a large amount of sludge (bottom sediment). ) is occurring.
これらの泥土は多量の水分を含有し且つ流動性であるこ
とから、産業廃棄物の「汚泥」扱いとなり、これを乾燥
及び固化して処分するには多額の処理コストがかかる。Since these muds contain a large amount of water and are fluid, they are treated as "sludge" of industrial waste, and a large amount of processing cost is required to dry and solidify this for disposal.

る。(Problem to be Solved by the Invention) The conventional methods of solidifying mud using the solidifying agent described above include methods in which the solidifying agent is sprinkled on the mud on the ground or in a pool and mixed mechanically, and mud is mixed in a stirring tank. However, in any case, the moisture content of the mud varies widely even if the source is the same, and in order to achieve sufficient solidification, a large excess amount of solidification agent must be added. I have no choice but to do it. Therefore, there is a problem that the cost of the solidifying material increases. Furthermore, in order to sufficiently mix the solidifying material, excessive mixing operations are similarly required, resulting in high energy costs. Furthermore, processing a large amount of mud requires a large area, and processing is difficult in mountainous areas such as tunnel construction or urban areas such as subways. Therefore, this places a heavy burden on the transportation of mud, which is difficult to handle.

It is to provide.

よりホッパー１１に送られる。FIG. 1 is a diagram for explaining the apparatus of the present invention as a whole. As shown in the first figure, the continuous mud solidification apparatus of the present invention includes a solidification material supply section A, a mud supply section B, and a solidification material-mud soil solidification system. It consists of a kneading section C. The solidified material supply section consists of a solidified material silo 1 and a solidified material receiving hopper 2, and the solidified material 3 is transported by, for example, a lorry and stored in the silo 1, and the required amount is supplied to the rotary pulp 4 of the silo 1 and the flow conveyor 5. It is then sent to hopper 2. At the bottom of this hopper 2, a powder feeding device 6 is provided that can control the amount of solidified material discharged. The solidified material supplied from the feeder 6 is sent to the hopper 11 by the injection screw conveyor 7.

処理泥土１４となる。The mud and solidifying material supplied as described above are sent to the hopper 10 of the kneading section C, kneaded by the extrusion kneader 11, and discharged. The thus discharged mud solidifies while being sent to the sand bit 13 on the discharge conveyor 12, loses fluidity and stickiness, and becomes a block-shaped treated mud 14 having a desired unconfined compressive strength.

一定以上の一軸圧縮強度の処理泥土を得るために大過剰
の同化材を必要としていた。The main feature of the present invention is that the solidification material and mud are mixed continuously. In other words, in the conventional technology, mixing of the solidification material and mud is mostly done batchwise even when mechanical stirring is used.
Because it relied on stirring bodies such as wheels and plates, and scrapers, it was impossible to uniformly disperse the solidifying agent, and therefore a large excess of assimilating agent was required in order to obtain treated mud with unconfined compressive strength above a certain level. .

As such a continuous mixer, a screw extrusion kneader, for example, a twin-screw kneader KRC kneader (manufactured by Kurimoto Iron Works) can be advantageously used.

。By using such a continuous mixer, the solidification material and mud are mixed uniformly, and the treated mud can be made to the desired strength with the appropriate amount of solidification material. There is no need to use it anymore. Furthermore, a large amount of mud can be continuously processed at the same time even in a narrow space by a small number of people.

By measuring t/rn') and multiplying these values, the weight fi (t/Hr) of the mud supplied per unit time can be obtained.If the water content of this mud is approximately constant, Since the amount of water supplied per unit time is required, it is possible to always mix a fixed ratio of solidification agent into the mud.

The setting is adjusted so that a fixed ratio of the solidifying material is supplied to this amount of water.

は次の様な関係式が成立する。(3) What is the water content ratio and unit volume weight N (wet density) of mud?
If the specific gravity of soil particles and the air gap ratio of soil particles are constant,
There is a relationship shown in FIGS. 2 and 3, and the water content ratio of mud can be predicted by measuring the wet density of mud. On the other hand, the relationship between the water content ratio and the unconfined compressive strength of the treated mud is as shown in Figure 4, and once the target strength of the solidified mud is determined, the water content ratio is determined. Further, as shown in Figure 5, the addition rate of the solidifying agent is determined by determining the target strength based on the relationship between the solidifying agent addition rate and the unconfined compressive strength. From FIGS. 4 and 5, if the unconfined compressive strength of the treated mud is 9u, the water content of the mud to be treated is W, and the amount of solidification agent added is a, the following relational expressions hold true for each of them.
（Ｋ、ｍ、ｎは各泥土によって決まる定数）１式の両辺

logk·11 Therefore, the target unconfined compressive strength of the treated mud is determined, and if the water content ratio of the mud can be measured, the amount of solidification agent added can be determined. The relationship between the amount of solidifying agent added and the unconfined compressive strength when the water content ratio of each mud is kept constant is as shown in FIGS. 6 and 7.

By calculating and controlling so that a predetermined amount of solidifying agent is added to this amount, treated mud having the target unconfined compressive strength can be stably obtained regardless of changes in the properties of the supplied mud.
