Drawings
FIG. 1 is a schematic diagram of the overall structure of the present utility model;
marking: a quarrying box 1, a slurry inlet pipe 2, a slurry inlet pipe gate valve 21, a slurry discharging pipe 3, a slurry discharging pipe gate valve 31, a bypass pipe 4 and a bypass pipe gate valve 41.
Detailed Description
The utility model will be further described with reference to specific examples and figures.
As shown in fig. 1, a bypass pipe structure of a quarrying box for a slurry shield comprises a quarrying box 1, a slurry inlet pipe 2, a slurry outlet pipe 3 and a bypass pipe 4. The pulp inlet pipe 2, the pulp outlet pipe 3 and the bypass pipe 4 are respectively provided with a pulp inlet pipe gate valve 21, a pulp outlet pipe gate valve 31 and a bypass pipe gate valve 41. The slurry inlet pipe 2 and the slurry outlet pipe 3 are respectively connected to the slurry inlet and outlet of the quarrying box 1, one end of the bypass pipe 4 is connected to the slurry inlet pipe 2 and positioned at the front side of the slurry inlet pipe gate valve 21, and the other end is connected to the slurry outlet pipe 3 and positioned at the rear side of the slurry inlet pipe gate valve 21.
In the tunneling of the shield tunneling machine, when the quarrying box 1 needs to be opened for cleaning, the slurry inlet pipe gate valve 21 and the slurry outlet pipe gate valve 31 are closed, then the bypass pipe gate valve 41 is opened, so that slurry flows to the slurry outlet pipe 3 through the bypass pipe 4, in addition, the quarrying box 1 is opened for cleaning, and the slurry outlet work can still be normally performed, thereby reducing the influence on the circulation system of the slurry balance shield when the quarrying box 1 is opened. After the quarrying box 1 is cleaned, the slurry inlet pipe gate valve 21 and the slurry outlet pipe gate valve 31 are opened, the bypass pipe gate valve 41 is closed, the quarrying box 1 is restored to normal operation and is put into use again, and slurry is discharged after flowing through the quarrying box 1.
In other embodiments, the bypass gate valve 41 may not be provided, and the bypass pipe 4 may be in a communication state for a long period of time only by controlling the on/off of the quarrying tank 1 through the slurry inlet gate valve 21. In addition, since the one-way valve is arranged on the slurry inlet and outlet of part of the quarrying tank 1, the slurry cannot return to the quarrying tank 1 through the slurry discharging pipe 3, so the slurry discharging pipe gate valve 31 is not required.
The above embodiments are only for illustrating the present utility model, and are not to be construed as limiting the utility model in any way, and any person having ordinary skill in the art will realize that equivalent embodiments of partial changes and modifications can be made by using the disclosed technology without departing from the scope of the technical features of the present utility model.
