Description

  The present invention relates to a waste disposal tool, and more particularly, to a waste disposal tool for treating waste discharged from a hopper of a pump car when raw concrete is placed.

Conventionally, in ready-mixed concrete placement, ready-mixed concrete is loaded onto a concrete mixer truck at a ready-mixed concrete plant, and the ready-mixed concrete is transported to the construction site of the structure using this concrete mixer truck. At the construction site, the ready-mixed concrete is thrown into the hopper of the pump car from the concrete mixer truck, and the ready-mixed concrete is placed in various places on the construction site using this pump car.
When the ready-mixed concrete is finished, the concrete remains in the hopper of the pump car.

  As a method of processing the concrete remaining in the hopper, a method of processing on the raw plant side or a method of processing on the construction site side is known.

As a method of processing on the raw plant side, the concrete remaining in the hopper of the pump car is transported as it is to the raw plant plant, and the concrete remaining in the hopper is discharged to the processing facility of the raw plant plant.
However, the processing facility of the raw concrete plant is for a concrete mixer truck and is not compatible with a pump truck. For this reason, in the method of processing on the raw plant side, after the concrete remaining in the hopper is discharged from the pump car to the processing facility of the raw plant, the concrete is further processed using a heavy machine, which requires labor and cost.
Therefore, it is desired to treat the concrete remaining in the hopper on the construction site side.

There are the following methods for processing on the construction site side.
First, for example, in a construction site, a concrete processing apparatus (see Patent Document 1) including a box-shaped main body into which concrete is poured and a vibration device that generates mechanical vibration in the main body is provided. There is a method of processing the concrete remaining in the hopper at the processing facility.
Second, there is a method in which the concrete remaining in the hopper is discharged from the hopper onto a blue sheet, and is transported after the concrete is hardened.
Japanese Patent Laid-Open No. 9-4231

Of the methods of processing on the construction site side, the method of processing the concrete remaining in the hopper at the processing facility is difficult to implement because it requires space in the construction site.
Here, after placing the ready-mixed concrete, the inside of the hopper of the pump car is cleaned. A large amount of water is used to clean the hopper of this pump car. Therefore, the concrete discharged from the hopper of the pump car contains a large amount of water.
Therefore, in the method of discharging the residual concrete from the hopper onto the blue sheet and carrying it out after the concrete has hardened, the waste mixed with a large amount of water and concrete will flow into the construction site and pollute the environment. There's a problem.
