Referring to fig. 2 to 6, the multi-mixer type fluidization treatment apparatus 3 is shown as a unitization treatment, which is divided into: an excavating soil conveyor 12, a water tank 13, a water feed pump 11, a slurry mixer 7, a solidified material mixer 6 and a feed pump 14.

The multi-mixer type fluidization treatment apparatus 3 can be mounted on a truck or other vehicle, and can be assembled on the vehicle after being mounted, and can be used in a loading state or a ground setting state.

The ground setting state will be described below. The conveyor 12 is a flat belt conveyor, and extends obliquely upward from an excavation earth charging hopper 15 on the front end side of the unit to the rear end side of the unit.

The water tank 13 is mounted below the conveyor 12 behind the feed hopper 15. The slurry mixer 7 is installed at the rear of the water tank 13 and at the rear end of the unit of the upper and lower unloading sections of the conveyor 12.

A water feed pump 11 is attached to the water injection pipe 9, the water injection pipe 9 connecting the water tank 13 and the slurry mixer 7. A manual cock 10 is attached to the water injection pipe 9 between the water feed pump 11 and the slurry mixer 7.

The curing material mixer 6 is arranged below, adjacent to the slurrying mixer 7. A transfer pump 14 is adjacent to the water injection pipe 9 between the slurrying mixer 7 and the water tank 13. A treated soil conveyance pipe 19 is connected between the suction side of the conveyance pump 14 and the solidified material mixer 6, and a conveyance port of the treated soil conveyance pipe 8 is connected to the discharge side of the conveyance pump 14.

Furthermore, the generator 1 is disposed next to the charging hopper 15 and on the unit front end side, and the table 4 and the control panel 2 are mounted separately next to the transfer pump 14 and the solidified material mixer 6.

In the slurry mixer 7, the sludge-cutting stirring blade 17 in the stirring tank 16 is controlled to rotate by the motor 18 on the lower side of the stirring tank 16. In the mud cutting stirring blade 17, three curved mud cutting teeth 17a extend from the outer periphery of the vertical rotation shaft 17b to the outer lower side.

The solidified material mixer 6 is provided with slurry stirring blades 20 in the stirring tank 5. In the slurry stirring blade 20, two movable teeth 20b extend outwardly from an upper peripheral portion of the vertical rotation shaft 20a, rotation is controlled by a motor 21 on the stirring tank 5, and two movable teeth 20c extend outwardly from a lower peripheral portion of the vertical rotation shaft 20 a. Further, four fixed teeth 20d are connected to the inner periphery of the agitation tank 5.

In the slurry mixer 7, the opening/closing port 22 is provided in the bottom wall of the stirring tank 16, and the opening/closing body 23 is openably and closably supported by the rotation center shaft 23a at the lower side of the bottom wall. The cylinder 24 is mounted on the underside of the bottom wall and is connected to the opening and closing body 23 by a piston rod 24 a. This cylinder 24 is driven and controlled by a pneumatic unit 25. When the piston rod 24a expands and contracts, the opening/closing body 23 rotates, and the opening/closing body 22 is closed or opened obliquely downward. In the solidified material mixer 6, the filter 26 has a side-by-side rod or net mounted on the agitation tank 5 directly below the opening/closing body 22. The opening/closing body 22, the opening/closing body 23, the cylinder 24, and the like constitute an opening/closing mechanism that opens the communication passage R space between the slurry mixer 7 and the curing material mixer 6.

Next, a method of treating excavated soil using the multi-mixer type fluidization treatment apparatus 1 will be described with reference to fig. 6. As shown in fig. 2, in the case where the excavated soil from the excavated hole H is put into the charging hopper 15 of the multi-mixer type fluidization treatment apparatus 1 at the time of backfilling, a certain predetermined amount of the excavated soil is conveyed by the conveyor 2 and falls into the agitation tank 16 of the slurry mixer 7. Further, a certain predetermined amount of water flows from the water tank 13 into the agitation tank 16 through the water injection pipe 9 by the water feed pump 11. Then, the excavated soil and water are slurried for a predetermined time by stirring with the stirring blade 17 of the slurrying mixer 7.

In the slurry mixer 7, when the switching body 23 is turned by the cylinder 24 and the opening and closing opening 22 is opened, water and the stirred slurry of the excavated soil fall from the opening and closing opening 22 into the space between the two

mixers

7,6 in this embodiment of the connecting passage R, and are filtered into the stirring tank 5 by the filter body 26 in the solidified material mixer 6.

On the other hand, an operator on the table 4 inputs a predetermined amount of the cured material into the agitation tank 5 of the cured material mixer 6. In addition, the timing of the application of the cured material is random. Then, the solidified material mixed with the slurry in the agitation tank 5 is agitated by the solidified material mixer 6 for a predetermined time to process the soil.

The treated soil is then sucked in from the solidified material mixer 6 through the conveying pipe 19 and discharged from the conveying pipe 8. In this way the fluidized treatment soil is backfilled again by means of the transport pipe 8 and solidified into the excavation H.

The following is the case of the linkage between the slurry mixer 7 and the solidified material mixer 6. When the slurry in the slurry mixer 7 is thrown into the solidified material mixer 6 in a predetermined amount, a predetermined amount of dredged soil also falls from the conveyor 12 into the slurry mixer 7. At the same time as the dredge is added to the slurry mixer 7, the treated soil is also produced in the solidified material mixer 6.

The present utility model has the following features (a) to (f).

a, the excavated soil can be easily backfilled into the excavated hole H of the excavated earthwork, so that the excavated soil can be reliably reused, the excavated soil does not need to be conveyed, the backfilling operation is rationalized, and the working efficiency is improved.

b the mixer is divided into a slurrying mixer 7 and a curing material mixer 6. The excavated soil is slurried with water in the slurrying mixer 7, and the solidified material is mixed into the slurry in the solidified material mixer 6 to become treated soil, and the two machines are operated under optimum conditions, respectively, to produce good fluidized treated soil. In addition, the slurrying mixer 7 and the curing material mixer 6 can be driven simultaneously and operated continuously under appropriate conditions, whereby the working efficiency can be improved. Further, since the

mixers

7 and 6 can be made smaller, the multi-mixer type fluidization processing apparatus 3 becomes more compact, and thus transportation and storage of the multi-mixer type fluidization processing apparatus 3 are facilitated.

c the transfer pump 14 can reliably backfill the treated soil from the solidified material mixer 6 into the excavation hole H.

d since the transfer pump 14 is directly connected to the mixer 6 for solidified material through the treated soil transfer pipe 19, the treated soil can be sucked from the mixer 6 for solidified material into the transfer pump 14 without passing through a hopper or a grid or the like. Therefore, the device does not need a hopper, a gate and the like, can realize light weight and compactness, can prevent blockage and leakage of the treated soil, and can smoothly transport the treated soil. Further, by merely reversing the operation of the conveying pump 14, air can be conveyed into the solidified material mixer 6 through the treated soil conveying pipe 19, improving the mixing property, and improving the quality of the treated soil.

e when the opening and closing body (23) rotates downwards and the opening and closing body (22) is opened, the slurry in the slurry forming mixer 7 is properly and regularly put into the solidified material mixer 6, so that good fluidization treatment soil can be generated, and the working efficiency can be improved. In addition, even in the closed state of the opening/closing body (22), sand in the slurry can be placed on the opening/closing body (22). In the open state of the opening/closing body (22), the opening/closing body (23) is inclined downward and away from the opening/closing body (22), sand is liable to fall from the opening/closing body (23), and the sand becomes less liable to be sandwiched between the opening/closing body (23) and the opening/closing body (22) due to the opening/closing body (22) being in the closed state.

f the soil blocks larger than the specified size in the slurry mixer 7 are filtered by the filter 26, and the other slurry is put into the solidified material mixer 6, thereby achieving stability and improving the quality of the treated soil.

In addition to the above embodiments, the configuration may be as follows.

a provides a mechanism for mixing the solidified material 6 in a similar manner to excavating soil and water. Other than the technical ideas and effects that can be grasped from the respective embodiments are described. As for the conveyor 12, the conveyor 12 drops the excavated earth into the slurrying mixer 7. Therefore, the excavated earthwork can be automatically put into the slurry mixer 7, and the excavated earthwork input work can be easily performed.

b a water tank of the stirring liquid tank 13 is used for connecting the stirring liquid tank 13 and the stirring liquid inlet channel water injection pipe 9 of the slurry forming mixer 7, and stirring liquid water is conveyed to the slurry forming mixer 7 from the water injection pipe 9 of the tank 13 and the pump 11. Thus, water can be automatically introduced into the slurrying mixer 7 to facilitate the casting operation.

According to the working claim 1, the opening and closing mechanism includes an opening and closing opening 22 provided in the slurry mixer 7, an opening and closing opening 22 and an opening and closing body 23, a cylinder 24 for opening and closing the opening and closing body 23 with respect to the opening and closing opening 22, and the opening and closing opening 22 communicates with the curing material mixer 6.

Thus, under a simple structure, excavated soil can be transferred from the slurrying mixer 7 to the solidified material mixer 6.

The foregoing is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto, and any person skilled in the art will be able to make insubstantial modifications of the present utility model within the scope of the present utility model disclosed herein by this concept, which falls within the actions of invading the protection scope of the present utility model.
