Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention treats residual soil generated by various types of construction, for example, road construction or crushed stone in a quarry, and scraped or excavated residual soil generated by underground construction such as subway or sewer construction. For normal disposal, transport to a distant treatment plant. The soil left at this site is transported by a small dump truck and temporarily stored in the soil hopper provided at the relay station. Further, the present invention relates to a residual soil hopper provided at a relay station where the residual soil is loaded on a large dump truck and carried out.

[0002]

2. Description of the Related Art As a conventional technique, for example, in a residual soil hopper having a crane that can be suspended and raised as a transportation means for residual soil and a hopper that stores the residual soil, the hopper is moved up and down by a lifting drive means. There is a residual soil hopper (see Japanese Patent Application Laid-Open No. 60-31447) that supports a lower loading space so that it can be formed and deleted.

[0003]

However, as a characteristic of the above-mentioned prior art, it is often practiced to store the residual soil excavated outside the carry-out time in the residual soil hopper. However, in order to shorten the residual soil treatment, there is a tendency to increase the capacity of the residual soil hopper, and accordingly, the hopper support member such as the crane also increases in size. In order to avoid this increase in size, a crane that can be suspended and lifted and a lifting device that lifts and lowers the hopper itself are provided. However, this conventional technique is very inefficient because the crane has to suspend its operation when the residual soil hopper is raised and the residual soil is discharged and placed on the large dump truck.
Moreover, there is a problem in that a large-scale device such as a crane and a crane for raising and lowering the remaining soil hopper is required. In view of this situation, the present invention cuts down at the construction site,
The excavated residual soil is transported by a small dump truck to the residual soil hopper installed at the relay station. The remaining soil is stored in the storage tank via a remaining soil raising and conveying device provided at an appropriate number of locations except at least one location around the storage tank of the remaining soil hopper. By doing so, the rotation efficiency of the vehicle from the construction site to the relay station is increased. As a result, it becomes possible to save waste land disposal costs, fuel costs, etc. Further, by providing an opening / closing device at the bottom of the storage tank, the residual soil in the storage tank can be discharged and loaded onto a large dump truck via the opening / closing device, so that a larger vehicle can be used from the relay station to the residual soil disposal site. It is intended to provide an excellent residual soil hopper capable of transporting residual soil.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a residual soil hopper, in which at least one portion around the storage tank is removed, and the residual soil conveyed by a small dump truck to a suitable number of locations. A technical means was adopted in which an apparatus for raising the remaining soil such as a bucket conveyor for receiving was provided, an entrance for a large dump truck was provided at the bottom of the storage tank, and an opening / closing device was provided at the bottom of the storage tank.

[0005]

As a result of adopting the above technical means, the present invention makes it possible to make a round trip on a relatively narrow road from the construction site to the relay station.
A small dump truck with a small turning speed collects and transports the remaining soil, and a large dump truck can transport and dispose of the remaining soil for round trips on a relatively wide road from the relay station to a distant disposal site. It is the best for the situation.
