As shown in fig. 1, in the conventional process for treating the residue soil generated by the earth pressure balance shield, the residue soil discharged from the shield machine is firstly stored in a residue soil pit 101, the residue soil is sent to a scraper conveyor 103 by an excavator 102, the scraper conveyor uniformly conveys the residue soil to a # 1 coarse screen 104 for water adding screening, oversize products fall into the residue field for stacking, undersize products enter an A slurry storage tank 118, are pumped into a B slurry storage tank 114 by a # 1 residue slurry pump 119 and then are pumped into a primary cyclone 105 by a # 2 residue slurry pump 115, overflow slurry of the primary cyclone 105 enters a C slurry storage tank 110 for re-separation, underflow coarse particle slurry of the primary cyclone 105 is injected into a primary dewatering vibrating screen 106, the oversize products fall into the residue field for stacking, the undersize products enter the B slurry storage tank 114 for re-circulation or enter the C slurry storage tank 110 through a communicating pipe 112 of the B slurry storage tank and the C slurry storage tank, and then are pumped into a secondary cyclone group 107 by a # 3 residue slurry pump 111, the overflow fine particle slurry of the second-stage cyclone group 107 enters a sedimentation tank 109, the underflow coarse particle slurry of the cyclone group 107 enters a second-stage dewatering vibrating screen 108, and coarse particles on the screen fall into a slag yard for stacking; and the fine particle materials penetrating through the screen are discharged into a C slurry storage tank 110 to be recycled or discharged into a sedimentation tank 109, the slurry precipitated in the sedimentation tank 109 is conveyed to a stirring tank 116 by a No. 4 slurry pump 113, a flocculating agent is added into the stirring tank 116, the slurry is stirred and then pumped into a chamber filter press 120 by a diaphragm pump 117 to be pressurized and dehydrated, and a filter cake is formed and then discharged.
The inventor finds in engineering practice that the traditional treatment process exposes the following three defects in engineering occasions in which the shield muck is only dehydrated and then discharged without recovering sandstone materials:
firstly, the number of the input equipment varieties is large, and the cost is high (the equipment comprises a No. 1 coarse screen 104, a No. B pulp storage tank 114, a No. 2 pulp pump 115, a first-stage cyclone 105, a first-stage dewatering vibrating screen 106, a C pulp storage tank 110, a No. 3 pulp pump 111, a second-stage cyclone group 107, a second-stage dewatering vibrating screen 108 and a sedimentation tank 109);
secondly, the running cost such as electricity charge, accessory consumption and the like is high, and the operation and maintenance are complex;
thirdly, the muck treatment equipment occupies a huge construction site.
