Abstract
The invention relates to a tunnel longitudinal drainage module, a tunnel drainage structure and a construction method.The tunnel longitudinal drainage module comprises a light filtering body, a longitudinal drainage pipe and a first waterproof plate capable of being connected with the inner side of a tunnel primary support, and the first waterproof plate is provided with a containing groove allowing the longitudinal drainage pipe to be placed and fixed; a plurality of water inlet holes are formed in the top of the longitudinal drainage pipe, the light filtering body covers a groove opening of the containing groove and covers the top of the longitudinal drainage pipe, and the tunnel longitudinal drainage module further comprises a fixing piece used for fixing the light filtering body to a primary support. According to the tunnel longitudinal drainage module, the tunnel drainage structure and the construction method, the problem that the position of a longitudinal drainage body in an existing tunnel drainage system is difficult to fix is solved.
