Abstract

The invention belongs to the technical field of tunnel engineering. The invention particularly provides a ballasted tunnel center ditch maintenance system and a ballasted tunnel center ditch maintenance method. The system comprises a central ditch and a working well which are used for draining water of the ballast tunnel, the working well comprises a well body and a cover plate. The cover plate isdetachably connected with the well body; the well body is connected with the side wall of the central ditch; the central ditch is communicated with the working well to form an overhaul channel, whenthe central ditch is blocked and needs to be overhauled, the bottom end of the well body is connected with the side wall of the central ditch through angle steel, the overhaul channel in the well is isolated from railway ballast outside the well through the well body, and workers and equipment can enter the central ditch from the well body to be overhauled. The problem that an existing high-speedrailway ballast tunnel center ditch is blocked and cleaned in time is effectively solved, the problem that drainage is not smooth due to blocking of the center ditch is fundamentally solved, and the tunnel structure safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering, and in particular relates to a maintenance system and method for a center ditch of a ballasted tunnel. Background technique [0002] Most of the existing tunnels use double-sided gutters and central cover ditch, and weep holes are set at the foot of the walls on both sides for drainage. The double side ditch is located on the side wall of the tunnel, and the central cover ditch is located under the track bed between the two lines. There is a Φ50 circular drainage blind pipe (perforated corrugated pipe) behind the second lining. Both ends of the circumferential blind ditch and the longitudinal blind ditch are directly connected to the side ditch of the tunnel. Tunnel side ditch. A Φ50 PVC drain hole is set in the middle of each longitudinal blind ditch to connect to the side ditch of the tunnel. The groundwater behind the lining is collected by the circumferential and vertical blind ...
