Up until now, the transportation of excavated soil discharged from the excavation hole, the mixing with solidification material, and the transportation and filling have only been partially mechanized, and there is no known device that can perform the entire process automatically and continuously. . Therefore, not only was the work of installing each machine extremely troublesome, but the work efficiency was extremely low. Furthermore, each piece of machinery must be transported separately as it moves from one construction site to another, making transportation extremely bulky and extremely inconvenient.

締め固めるとよい。 First, the base 1 is moved to bring the shovel 4 close to a required drilling hole. Thereafter, the discharged excavated soil is loaded onto a belt conveyor 5 for transporting excavated soil using a shovel 4, and is conveyed and discharged into a two-shaft forced mixing mixer 6. At the same time, the required amount of soil improvement solidification material is weighed using a measuring device 11 and is charged into the biaxial forced mixing mixer 6 using a charging screw conveyor 12. Then, the excavated soil and the ground improvement solidification material are stirred and mixed using the biaxial forced mixing mixer 6 for a required period of time. At this time, the biaxial forced kneading mixer 6 is provided with swirling flow in the horizontal plane in addition to counterflow in the vertical plane, so that even stirring and mixing can be carried out in a short time. Thereafter, the mixed soil is transferred to the discharge belt conveyor 15 and transported, and is again filled into the excavated hole. At this time, it is preferable to freely adjust the length of the discharge belt conveyor 15 so as to position it above the excavated hole. It is best to compact the filled mixed soil with a shovel 4.

Since this invention is configured as described above,
The excavated soil discharged from the excavated hole by the excavation machine is loaded onto the belt conveyor 5 for conveying excavated soil by the shovel 4, and then conveyed and discharged into the biaxial forced mixing mixer 6, and at the same time,
The required amount of soil improvement solidification material is introduced using the input conveyor 12, and the excavated soil and soil improvement solidification material are stirred and mixed by the twin-shaft forced mixing mixer 6, and then excavated using the discharge belt conveyor 15. This device can be used to re-inject and fill the excavated soil into the excavated hole, and is capable of continuously and automatically stirring and mixing the excavated soil with the ground improvement solidification material before injecting and re-filling the excavated soil into the excavated hole, which is superior to conventional technology. and very smoothly,
Moreover, you can work efficiently. Also,
Since the base 1 is movable, it is not only easy to install the device, but also easy to move to a desired work site. Furthermore, since the twin-screw forced kneading mixer 6 is used, even stirring and mixing can be performed in a short time.
