Abstract

The invention discloses a novel tunnel waterproof and drainage system which comprises a water filtering layer; water collecting plates each of which is located between a secondary lining and the water filtering layer, wherein the outer side face of the water collecting plate inclines towards the middle, and the water collecting plate is provided with a corrugated section; a waterproof layer which is arranged between the secondary lining and the water collecting plate; annular drainage pipes, wherein the outer side face of each water collecting plate is provided with the corresponding annular drainage pipe; a vertical drainage pipe which is communicated with the annular drainage pipe; sewage collecting grooves which are formed in arch feet on the two sides of a primary support; longitudinal drainage pipes, wherein each longitudinal drainage pipe is arranged between each sewage collecting groove and the water collecting plate, and the sewage collecting grooves are communicated with the longitudinal drainage pipes; side water collecting ditches which are formed in arch feet on the two sides of the secondary lining; transverse drainage pipes which are used for communicating the longitudinal drainage pipes and the side water collecting ditches on the same side; and transverse blow-off pipes which are used for communicating the sewage collecting grooves and the side water collecting ditches on the same side. The waterproof and drainage system has the advantages of being exquisite in structure, remarkable in waterproof, drainage, seepage-proofing and anti-blocking effects and the like.

Description

technical field [0001] The invention relates to the technical field of tunnel waterproof and drainage construction, in particular to a novel tunnel waterproof and drainage system. Background technique [0002] In the existing tunnel waterproof and drainage construction technology, the water behind the secondary lining is finally collected to the central drainage ditch through the horizontal drainage pipes by setting up circumferential, vertical, and longitudinal drainage pipes and other components and materials after the initial support of the tunnel and out of the hole. Although the existing tunnel waterproof and drainage system has played its due function to a certain extent in the process of tunnel construction and operation, a large number of tunnel practices and operations in recent years have shown that many tunnels using the existing waterproof and drainage system are put into operation After a few years, there will be different degrees of water leakage. If the tunn...
