Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excavation and earth removal treatment system used for the purpose of treating excavation and earth removal during excavation work such as pipe burial work.

[0002]

2. Description of the Related Art Generally, excavated soil excavated by an excavator such as a well-known backhoe during excavation work such as pipe burial work is directly loaded on the dump truck by the excavator and transported to a landfill site for disposal. To be done.

However, when the excavator discharges excavated soil into a dump truck, a large amount of dust is generated, which causes a great deal of trouble to the neighborhood against the intention of the owner, and the excavated soil is loaded into the dump truck. However, the work efficiency was not good because it was intermittent.

Therefore, recently, a tank car equipped with a recovery tank for recovering excavated soil and a vacuum suction car equipped with a separator / drainer, a vacuum pump, a discharge silencer, an independent engine for driving the vacuum pump, and the like are prepared. ,
The vacuum pump of the vacuum suction car applies negative suction pressure to the recovery tank of the tank car, and the worker holds the suction nozzle attached to the tip of the suction hose connected to this recovery tank and excavates it with an excavator. By bringing the excavated soil into contact with the excavated soil, the excavated soil is sucked and collected from the suction nozzle through the suction hose into the collection tank of the tank truck and loaded. As a result, the excavated soil can be loaded efficiently without causing any trouble in the vicinity.

[0005]

However, in the above method, the diameter of the suction hose is small because the suction hose that functions as a suction path for excavated soil and the suction nozzle attached to the tip of the suction hose are operated manually. Can be easily operated by human power, but when a large tank truck is used with a large amount of excavated soil, the diameter of the suction hose is correspondingly increased, which increases the weight. Since there is also a pulsation during suction, it is very difficult to manually operate the suction hose and the suction nozzle.

Further, since the excavated soil is transported by the tank truck, when treating a large amount of excavated soil, many expensive tank trucks must be prepared, which is expensive and economically disadvantageous. is there.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an excavation and earthmoving treatment system capable of performing the treatment of excavation and earthmoving with high efficiency and at low cost.

[0008]

In order to achieve the above object, the present invention has a suction excavator in which a suction pipe is connected to an excavation attachment mounted at the tip of an arm, and a proximal end portion of the suction pipe of the suction excavator. An excavation and excavation carrier equipped with an airtight detachable body that is detachably mounted on the excavated soil excavator and a vacuum suction connected to the detachable body of the excavator and excavator by an intake hose. The excavation and dumping and loading system is composed of a vacuum suction vehicle equipped with the device.

Further, a suction excavator having a suction pipe connected to the excavation attachment attached to the end of the arm, a recovery tank connected to the base end of the suction pipe of the suction excavator via a soil discharge suction hose, and The excavation and soil disposal system is constructed from a vacuum suction truck with a recovery tank equipped with a vacuum suction device.

[0010]

According to the present invention, the excavated soil excavated by the excavation attachment of the suction excavator is sucked into the detachable body of the excavated soil excavation carrier via the suction pipe and the suction hose, and then stored. When the inside of the desorption body of the carrier is full of excavated soil or when the excavation work is completed, the excavated soil carrier will discard the excavated soil.

Further, the excavated soil excavated by the excavation attachment of the suction excavator is sucked and accommodated in the recovery tank of the vacuum suction vehicle with the recovery tank via the suction pipe and the suction hose, and the vacuum suction vehicle with the recovery tank is accommodated. When the inside of the recovery tank is full of excavated soil, or when the excavation work is completed, the excavated soil is discarded by a vacuum suction truck with a recovery tank.
