specific Embodiment approach

[0048] The specific embodiment of the separation system that the present invention is used for tunnel sewage treatment is as follows:

[0049] Excavate the dregs pool 11 at a position close to the tunnel, install a bracket 13 in the dregs pool 11, and install the box body 12 on the bracket 13;

[0050] The sewage in the tunnel is driven into the sewage pipe through the pump body, and enters the corresponding sedimentation space 1231 through the feed port 121, and flows into the adjacent sedimentation space 1231 through the flow holes on the partition plate 123, and passes through several sedimentation spaces 1231 After the graded sedimentation, it flows into the sedimentation space 1231 of the final stage, and at this time, the sedimentation space 1231 is the supernatant liquid separated from the sewage;

[0051] The supernatant in the final settling space 1231 is discharged from the outlet pipe to the waterway through the outlet 122, and the hoisting device 125 is operated to...

Abstract

The invention relates to a separation system for tunnel sewage treatment. The separation system comprises a slag pond excavated and formed on the periphery of a tunnel; a tank body erected above the slag pond, wherein openings are formed on the top and bottom of the slag pond, and the tank body is used for accommodating the sewage generated by tunnel construction; and a bottom sealing structure arranged on the bottom of the box body in an opening and closing manner, wherein the slag precipitated in the box body can be discharged into the slag pond by opening the bottom sealing structure. The problem that the slag is hard to discharge is effectively solved, the slag can be directly discharged into the slag pond by opening the bottom of a sedimentation pond, the manpower and the material resources are saved, the construction efficiency is improved, and the construction progress is guaranteed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a separation system for tunnel sewage treatment. Background technique [0002] During shield excavation, due to reasons such as shield machine water, segment washing, and groundwater, a large amount of sewage and sand will be generated. These sewage and sand will collect at the tail of the shield and need to be pumped out of the tunnel and then placed in the sedimentation tank at the tunnel entrance. After sedimentation in the tank, the clear water is discharged into the sewer, and the sediment is discharged into the muck pond. [0003] Most of the existing sedimentation tanks use water pumps to pump out the clean water after the sewage sediment has settled, and then manually or use an excavator to dig out the sediment from the sedimentation tank and then discharge it into the muck tank. This method consumes manpower and material resources. The construction efficiency is red...
