DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for transporting a soil conditioner, for example, for carrying a soil conditioner to a roof of a building for rooftop greening.

[0002]

2. Description of the Related Art When rooftop greening is performed, it is necessary to carry a soil improvement material to the rooftop. For this purpose, soil improvement materials have conventionally been carried in using cranes and temporary elevators.However, when using such cranes and temporary elevators, it is necessary to adjust the process with other construction work. In addition, it may be difficult to secure a crane installation location due to other building materials and circumstances around the building.

[0003] When a fluid such as concrete is conveyed, it can be pushed up to the ground by a plunger type pump. However, since the soil improvement material is a powder, a large amount of air is mixed in, and the plunger type is used. When a pump is used, it is known that the pipe is compressed during transfer and blocks the inside of the pipe.

[0004] Therefore, in order to feed powder such as soil improvement material by pressure, it is effective to carry the powder by moving it in a flow of air in a moving pipe by a blower (blower). When moving, a certain amount of vacuum (vacuum suction pressure) is required because the mass of the mass affects the blower alone.

[0005] The above-mentioned soil improvement material is transferred not only when the soil improvement material is transferred from the ground to a high place in a building, but also in a remote place where a transportation means such as a dump truck or the like or a crane cannot reach. Transferring to a location or a remote location is similarly problematic.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a powdery soil improving material can be raised by moving air in a pipe without using a crane or a temporary elevator. It is an object of the present invention to provide a method and an apparatus for transferring a soil amendment to be transferred to a place or a remote place.

[0007]

In order to solve the above-mentioned problems, a method of transferring a soil conditioner according to the present invention is to provide a discharge tank at a high place or a remote place, and a suction pipe communicated with the discharge tank. The inside of the discharge tank is depressurized by a vacuum suction device provided on the ground side, and an opening / closing lid provided at the bottom of the discharge tank is closed by the depressurization in the discharge tank, while communicating with the discharge tank. Operating the vacuum suction device after sucking up the soil conditioner into the discharge tank by exerting a suction force due to the reduced pressure in the discharge tank on the soil conditioner supplied to the ground side through the suction pipe that is provided. Recovering the reduced pressure in the discharge tank by opening the open / close lid of the discharge tank by its own weight to discharge the soil improving material accumulated in the discharge tank. .

[0008] Further, the device for transferring soil improvement material of the present invention comprises:
The powdery soil conditioner is transferred to a discharge tank installed at a high place or a remote place, and the soil conditioner stored in the discharge tank is discharged to transfer the soil conditioner to a high place or a remote place. The soil improvement material transfer device, wherein the discharge tank includes a suction pipe connected to a vacuum suction device provided on the soil improvement material side and a suction pipe guided to the soil improvement material. While being connected, the discharge tank has an open / close lid at the bottom, and the open / close lid is closed by depressurizing the inside of the discharge tank in response to the operation of the vacuum suction device, while the inside of the discharge tank is closed. When the reduced pressure is restored, the open / close lid is opened by the weight of the open / close lid or the weight of the soil improving material, whereby the soil improving material in the discharge tank is discharged.
