The utility model for achieving the above object, be achieved through the following technical solutions: major diameter slurry shield high pressure flushing device, comprise water tank and the first booster pump group, the first booster pump group is made up of the first booster pump of several series connection, the import of the first booster pump group connects water pump, the outlet installation high-voltage pipeline of the first booster pump group, pressure piping has two outlets, two outlets of pressure piping all communicate with water tank, water tank arranges four outlets, an arm is all installed in each outlet, and arm communicates with the bubble storehouse of shield machine.
For further realizing the purpose of this utility model, can also be by the following technical solutions: the quantity of described the first booster pump is two, second booster pump is all set on described each arm, on described pressure piping, valve is set, connecting hole is offered in described water tank upper end, stationary magazine creel is set on connecting hole, on stationary magazine creel sidewall, offer air vent, stationary magazine creel top arranges external screw thread, external screw thread is positioned at air vent top, fixed cover is set on stationary magazine creel, fixed cover bottom arranges internal thread, stationary magazine creel is threaded with fixed cover, screwed hole is offered in fixed cover upper end, adjusting screw(rod) is set in screwed hole, adjusting screw(rod) is threaded with fixed cover, adjusting screw(rod) lower end fixed installation spring, spring lower end arranges connection ball, spring is given all the time and is connected downward thrust of ball, connect ball and be positioned at stationary magazine creel, connect the diameter of ball identical with the internal diameter of stationary magazine creel.
The utility model has the advantage of: in the utility model, by pressure piping, water tank and multiple booster pump are set, making current carry out high pressure near the earth early gate of excavation storehouse washes away, quantity and the size of earth piece are reduced greatly, make the output of mud unblocked, thereby the quarrel mound that has solved excavation storehouse is long-pending, clay easily bonds, stops up the deficiencies such as easy pipeline, plasma discharge be smooth, has guaranteed that the effective plasma discharge of the shield structure circulating system and shield machine tunnel smoothly.The utility model also uses the clear water of underground water source, in the time that mud is exported, has reduced mud balance, has alleviated the pressure of output channel, has met the construction requirement of the normal driving of shield machine, has improved shield machine construction efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation; Fig. 2 is the I portion structure for amplifying schematic diagram of Fig. 1.
Reference numeral: 1 first booster pump 2 pressure piping 3 water tank 4 arm 5 second booster pump 6 bubble storehouse 7 valve 8 connecting hole 9 stationary magazine creel 10 air vent 11 fixed cover 12 adjusting screw(rod) 13 springs 14 connect ball.
The specific embodiment
Major diameter slurry shield high pressure flushing device, comprise water tank 3 and the first booster pump group, the first booster pump group is made up of the first booster pump 1 of several series connection, the import of the first booster pump group connects water pump, the outlet installation high-voltage pipeline 2 of the first booster pump group, and pressure piping 2 has two outlets, two outlets of pressure piping 2 all communicate with water tank 3, water tank 3 arranges four outlets, and an arm 4 is all installed in each outlet, and arm 4 communicates with the bubble storehouse 6 of shield machine.This structure is by arranging pressure piping 2, water tank 3 and multiple booster pump, and the clear water that uses underground water source carries out high pressure near the earth early gate of excavation storehouse and washes away, quantity and the size of earth piece are reduced greatly, make the output of mud unblocked, thereby the quarrel mound that has solved excavation storehouse is long-pending, clay easily bonds, stops up the deficiencies such as easy pipeline, plasma discharge be smooth, in the time that mud is exported, reduce mud balance, alleviate the pressure of output channel, the construction requirement that has met the normal driving of shield machine, has improved shield machine construction efficiency.
The quantity of described the first booster pump 1 is two.This structure has increased water flow pressure, has reduced quantity and the size of the earth piece in excavation storehouse.
On described pressure piping 2, valve 7 is set.Valve 7 is connected with monitoring system with flush water control.This structure is convenient for people to control and monitoring streamflow regime.
