Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 The shown sewage reuse device for shield tunneling includes sewage tank 1, mud pump 4 and flowmeter 5. A valve 2 is provided between the outlet of sewage tank 1 and the inlet of mud pump 4. Valve 2 can be a ball valve. The outlet pipeline of the mud pump 4 is provided with a flow meter 5, the outlet pipeline of the mud pump 4 is connected to the soil bin 6, and the inlet and outlet of the mud pump 4 are provided with a shock absorber 3 to avoid excessive impact of sewage on the If the pipeline is damaged, a branch is provided on the outlet pipeline of the mud pump 4 and between the shock absorber 3 at the outlet end and the flow meter 5. The outlet of the branch is connected to the slag truck 8, and the branch A throttling valve 7 is provided on the road, and the amount of sewage injected into the soil bin 6 i...

Abstract

The invention discloses a shield construction waste water recycling device and relates to the technical field of shield construction. The shield construction waste water recycling device comprises a waste water tank, a slush pump and a flowmeter, wherein a valve is arranged between the outlet of the waste water box and the inlet end of the slush pump; an outlet pipeline of the slush pump is connected with a soil bin; shock absorbers are arranged on the outlet and the inlet of the slush pump; the flowmeter is arranged in the back of the shock absorber of the outlet end; a branch is arranged in front of the flowmeter and is communicated with a slag car; a throttle valve is arranged on the branch. Waste water in the waste water box is pumped and conveyed to the soil bin by the slush pump; the main flow is controlled by the valve at the outlet of the waste water box; the impact of the waste water can be weakened by the shock absorbers which are mounted in front of and in the back of the slush pump, the throttle valve is adjusted according to the display of the flowmeter and the actual requirement, the flow of the waste water injected into the soil bin is controlled, and the waste water surplus which is not utilized is conveyed to the slag car for outward transport through controlling the flow of the branch by the throttle valve. The shield construction waste water recycling device has the advantages that the structure is simple, the manufacturing cost is low, and the utilization rate of water source is improved.

Description

technical field [0001] The invention relates to the technical field of shield tunneling construction. Background technique [0002] At present, in the shield tunneling method subway construction project, during the tunneling process using the shield machine, a large amount of sewage will be generated due to washing the trolleys and segments, etc., and the sewage needs to be discharged outside the tunnel to ensure normal tunneling. Therefore, a sewage tank and a sewage pump are installed on the trailer at the end of the shield machine, and a sewage pipe with a diameter of 100mm is installed in the tunnel. Through these equipment, the sewage is discharged to the entrance of the cave, and the sewage is pumped to the sedimentation tank on the ground at the entrance of the cave. Because the sewage contains a lot of mud, sand, cement, etc., it is often necessary to spend manpower and material resources to clean the sedimentation tank. If all these sewage are discharged out simply...
