Description of the Related Art Conventionally, in order to build a foundation for a structure, powdery solidifying material such as cement is agitated and mixed with the bottom ground such as a dam, and the improved soil is transported to the foundation where the structure is built. It is used as a base material, or the ground material is improved by stirring and mixing the solidifying material directly with the foundation. And
The ground is improved by using a well-known backhoe equipped with a ground improvement device at the tip of the arm.Before that, the ground to be improved is divided into many areas in consideration of the mixing ratio of solidifying material and soil. The solidified material is discharged from the cyclone into the weighing box, which is installed on the upper surface of the ground for each section and whose upper and lower surfaces are open, and is discarded.

公害が防止されることとなる。In order to achieve the above object, a solidifying material weighing box used for ground improvement according to the present invention forms a hollow weighing box main body by surrounding only the bottom and opening the bottom. The weighing box body is provided with a cyclone for discharging powdery solidifying material such as cement into the weighing box body and a dust collecting device for collecting the solidifying material soaring in the weighing box body. . The solidified material weighing box is attached to the tip of the arm of the backhoe, and the inside of the weighing box body is hermetically sealed when installed on the ground top. As a result, even if the solidifying material is discharged from the cyclone, the solidifying material does not scatter to the outside of the weighing box main body, so that the supply loss is eliminated and dust pollution is prevented.

る。The amount of the solidifying material accumulated on the ground upper surface E in the weighing box body 1 is determined by the vertically long sight window 9 and scale 9 provided on the side wall 8a.
Since it can be confirmed through a, the discharge amount can be accurately known and the adjustment can be easily performed. Therefore, when an appropriate amount of the solidifying material is accumulated, the backhoe 10 is moved to change the position of the ground upper surface E, and the solidifying material is sequentially discarded by an appropriate amount.
After that, the ground will be improved by a stirring and mixing device (not shown). Although the measuring box body 1 is formed by using a steel plate, it may be formed by a transparent synthetic resin if it is possible by design. In this way, the inside can be easily seen and the discharge amount of the solidifying material can be improved. Can get to know more accurately.
