Detailed Description
The present invention will be described in detail with reference to the following embodiments.
The utility model relates to a sewage-cleaning and diversion system for TBM tunnel downslope drainage, which comprises a longitudinal central drainage ditch 1 at the inverted arch of the tunnel, and longitudinal lateral drainage ditches 4 or temporary drainage pipes 3 at the two sides of the tunnel in two lining sections, wherein the outer sides of the lateral drainage ditches 4 or the temporary drainage pipes 3 are communicated with longitudinal blind pipes 6 at the arch feet through transverse drainage pipes 7; construction sewage in the tunnel is scattered and collected and flows to a tunnel opening 2 along the slope through a central drainage ditch 1; the clean water seeped out of the surrounding rock behind the lining of the two lining sections flows out of the hole through the lateral drainage ditch 4 or the temporary drainage pipe 3.
The secondary lining section includes a side drain unfinished portion and a side drain finished portion, and a temporary drain pipe 3 is provided at a side drain position of the side drain unfinished portion to be longitudinally accessed to a side drain 4.
The front of the second lining section is a tunneling section 11 and a primary lining section 12 of the tunnel in sequence, and a transverse temporary water retaining wall 5 is arranged between the primary lining section 12 and the second lining section. The temporary water retaining wall 5 is a mortar concrete wall body, is arranged at the end part of the temporary drain pipe 3 and plays a role in plugging, and prevents sewage collected by the tunneling section 11 and the primary lining section 12 from flowing into the temporary drain pipe.
