Abstract
A water supply system of a composite earth pressure balance shield moves with a shield cabinet vehicle. A water pump outside a tunnel automatically compensates water for a water storage tank through a water supply pipe winding drum by means of signals of a liquid level sensor. A water supply pump absorbs water from the water storage tank. A water pump I provides water for a hydraulic oil cooling device, cooled hot water is retained to provide water for the cabinet vehicle, a manual brake, secondary slurry filling and a sewage pump washing water feeding inlet, the surplus water is pressurized through a water pump V and then flows into a municipal administration sewage discharge pipe network through a water discharge pipe winding drum and a water supply device for ground mortar mixing. A water pump II provides water for an air compressor, a power distribution cabinet, a gear oil tank, a hydraulic motor reduction box cooler, and the cooled hot water returns to the water storage tank. A water pump III provides water for a foaming liquid mixer, a synchronous slurry filling pump washing loop. A water pump IV provides water for a shield tail slurry filling opening washing loop. A sewage pump is installed at the tunnel water accumulation position to pump water. Washing return water and pump sewage pass through a solid-liquid separator, and waste water enters a sewage tank and then is discharged through a water pump V which starts automatically by means of signals of the liquid level sensor. The water supply system has the advantages of being constant in cooling effect and capable of recycling waste water.

The specific embodiment
A kind of composite balancing earth-pressure shielding machine water system as shown in Figure 1 comprises feed pipe reel 1, water pump I 2, water storage box 3, water pump II4, air compressor machine cooler 5, power distribution cabinet cooler 6, gear oil sump cooler 7, hydraulic oil cooler 8, hydraulic motor reductor cooler 9, the chassis reservation mouth of a river 10, Ren Zha feed water inlet 11, secondary grouting feed water inlet 12, foam solution blender 13, shield tail grouting port flush loop 14, tunneling synchronous mud injecting pump flush loop 15, water pump III16, water pump IV17, foul water pump 18, solid-liquid separator 19, foul water tank 20, water pump V21, gutter reel 22, ground mortar mixing supply equipment 23.
In the shield machine tunneling process, supply-water pump supplies water to water storage box 3 through feed pipe reel 1 outside the tunnel, and the liquid level sensor on the water storage box 3 sends liquid level signal control surface water switch pump, realizes automatic water supplement.
Water pump I 2 starts with water pump V21 is chain simultaneously, and the cold water that water pump I 2 draws is through 8 pairs of hydraulic oil coolings of hydraulic oil cooler, and the water of cooling hydraulic oil flows out after the cooler, and dividing has branch road behaviour lock feed water inlet 11 and secondary grouting feed water inlet 12 interim waters to supply water; Be distributed in the reservation water nozzle 10 that respectively saves on the chassis and can open the valve water at any time; Cooling water also is used for washing foul water pump 18 blowoff lines, and the sewage of flushing flows into solid-liquid separator 19 slag removal and purifications, and the waste water after the purification enters foul water tank 20; Part residue cooling used beat water is discharged outside the hole by water pump V21 and is utilized.Cooling used beat water has improved the utilization rate of water resource through repeatedly recycling, plays the effect of energy-saving and water-saving.
The cold water that water pump II4 draws is to equipment such as air compressor machine cooler 5, power distribution cabinet cooler 6, gear oil sump cooler 7, hydraulic motor reductor cooler 9 parallel connection cooling; Cooling back current are got back to water storage box 3; With initiate cold water mix cooling recycling in the water storage box; Because initiate cool water quantity much larger than water pump II4 recirculated cooling water amount, so neither influence next circulation cooling effect, has been saved great lot of water resources again.
When needs added foam improvement excavation soil property environment, opening water pump III16 was that foam solution blender 13 supplies water; Water pump III16 water supply branch road is used for washing tunneling synchronous mud injecting pump flush loop 15, and the sewage of flushing flows into foul water tank 20 after solid-liquid separator 19 purified treatment.
When synchronous grouting finishes, when needing the flushing grouting port, open water pump IV17 to 14 flushings of shield tail grouting port flush loop, the sewage of flushing flows into foul water tank 20 after solid-liquid separator 19 purified treatment.
When ponding in the tunnel surpassed warning line, dredge pump 18 started automatically, ponding in the tunnel is expelled to solid-liquid separator 19 purified treatment after, flow into foul water tank 20.
When water pump I 2 does not open; Water pump V21 opens waste discharge automatically according to the liquid level sensor signal that is equipped with on the foul water tank 20; The waste water of discharging is through outside the gutter reel 22 discharge tunnels, and out outlet, tunnel part current flow directly into municipal blowdown pipe network, and it is that the mortar mixing is supplied water that the delivery port branch has branch road to connect ground mortar mixing supply equipment 23 pipelines; Waste water is reused once more, save great lot of water resources.
This water system of new research and development; Water storage box 3 advances with the shield machine chassis with water pump, and each supply-water pump and water storage box relative distance are constant, and the water supply line distance is constant; Overcome the low defective of pressure current prompt drop that supplies water and cause by the long distance of single water pump, guaranteed constant cooling effect; Through reasonable Arrangement discharge of wastewater and scrubbing loop, make that the waste water of discharging is repeatedly reused simultaneously, greatly save water resource.
