Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an excavator, and more particularly to a shield treatment device that supplies mud to the excavator body and processes slime, that is, muddy water discharged from the excavator body, and an excavator. The present invention relates to an excavation rig equipped with a mud making device that creates mud water necessary for the machine body, and a waste mud water treatment device that processes waste mud water into clean water.

For example, when excavating a tunnel using a drilling device, the excavation can be carried out safely by transporting muddy water (slime) to the surface, suppressing the collapse of the strata, and preventing the eruption of gas, water, etc. that exist underground. So muddy water is used.

Furthermore, from the viewpoint of preventing pollution of rivers, etc., it is currently not possible to directly discharge muddy water (slime) into rivers, etc., so silk processing and waste muddy water processing is carried out. By the way, in conventional equipment, the hem processing equipment, mud preparation equipment, and waste mud treatment equipment were each independent, that is, disparate and unrelated to each other, so piping connections between the equipment were required during each treatment process. , adjustment between the devices must be made, and this work is extremely troublesome and is one of the major causes of a decline in excavation efficiency.

The present invention enables troublesome piping connections, adjustments between the devices, etc. to be performed by constantly connecting piping between a loss treatment device, a mud production device, and a waste mud treatment device, and controlling each pump installed in the piping.

Regarding the operation of the bleaching treatment apparatus B, press the operation pushbutton 0 on the central operation panel (not shown) and check the operation of the hawking machines A27 and A28 of the adjustment tanks 27 and 28.

After issuing a warning for a certain period of time, the belt conveyor for bleaching is set to M2.
Operate in the order of 5-C, M22, M25-A, and M25-B. Since the belt conveyor M25-C is related to other work, an operation command is given to the belt conveyor M25-C and it is confirmed whether or not it has been operated. Simultaneously with the above alarm, automatic operation of the pump P26 of the caisson furnace liquid tank 26 is started.

Pump P26 is used during bleaching treatment (excavation treatment and separation treatment) (belt conveyor M25-A, M2
5-8) is turned on at the upper limit of the level switch F26 of the caisson furnace liquid tank 26, turned off at the lower limit, and is stopped when the anchor treatment is completed. Also, a plurality of motors, for example, three motors of the caisson separator 24, M24-A, M24-8, M24-C
After the timer setting time, the cyclone supply V supply pump P21 is operated. After the time set by the timer, it is determined whether or not the main unit is to be excavated (whether a mud water transport command has been received), and if there is a transport command, the excavation process is performed, and if there is no transport command, the separation process described below is performed.

If there is a transport command, it is confirmed that the waste mud water extraction pump P28, the phosphoric acid water supply pump P46, and the mud production water supply pump P49 are not operating, and that the liquid level in the adjustment tanks 27 and 28 is the level switch L2.
7 After confirming that it is not below the lower limit, mud screen 2

When M68-C stops, belt conveyor M25-
Issue a stop command to C. Then repeat the automatic operation described above. As explained above, the excavation equipment according to the present invention can connect the excavator main body, hem processing equipment, mud production equipment, and waste mud water treatment equipment without having to make complicated piping connections or adjustments between equipment as in the past. By controlling the pump installed in the connected piping, it is possible to supply mud to the excavator, process the anchor-mixed mud from the excavator, create the mud necessary for the excavator, and clean the waste mud. Therefore, excavation work can be carried out extremely efficiently.

Claims (1)

[Claims] 1 An excavator body, a treatment device that supplies muddy water to the excavator body and processes the mixed muddy water discharged from the excavator body, a mud making device that makes the muddy water necessary for the excavator body, and a waste muddy water The mixed mud water discharged from the excavator body is sent to the treatment equipment and treated, and the treated mud water is adjusted together with the mud water mixed with the mud making equipment. ■The treated mud from the treatment equipment and the mixed mud from the mud making equipment are adjusted in the adjustment tank of the treatment equipment and sent to the excavator, and then disposed of from the adjustment tank. The mud water is sent to the waste mud water treatment equipment and treated as fresh water, and these excavator bodies, processing equipment, mud making equipment, and waste mud water treatment equipment are constantly connected to each other by piping equipped with pumps. By controlling these pumps, it is possible to supply mud to the excavator, process mixed mud from the excavator, create mud necessary for the excavator, and clean the waste mud. A drilling rig characterized by its shape.
