Description
Technical Field
The utility model belongs to the technical field of tunnel engineering, concretely relates to there is tiny fragments of stone, coal, etc. tunnel center ditch manhole.
Background
The existing tunnel is mostly provided with a bilateral ditch and a central cover plate ditch, drainage holes are arranged at the wall feet at two sides for drainage, wherein the central cover plate ditch bears the main drainage function, and the bilateral ditch assists in drainage. The two side ditches are located on the side of the side wall of the tunnel, and the central cover plate ditch is located below the ballast bed between two lines. And a phi 50 annular drainage blind pipe (a perforated corrugated pipe) is arranged behind the two linings, the two ends of the annular blind ditch and the two ends of the longitudinal blind ditch are directly communicated with the tunnel side ditch, and the middle part of each section of the longitudinal blind ditch is provided with a phi 50PVC drainage hole connected to the tunnel side ditch. And a phi 50PVC drainage hole is arranged in the middle of each section of longitudinal blind ditch and connected to the side ditch of the tunnel. Underground water behind the lining is collected through the annular blind pipes and the longitudinal blind pipes and then discharged into the side ditches, is collected and precipitated through the side ditches, is introduced into the central cover plate ditch through PVC transverse water guide pipes at intervals of 30 m phi 100, and is discharged out of the hole through the central cover plate ditch.
As the line in the tunnel is a ballast track bed, in order to meet the related requirements of the maintenance rules of the ballast track line of the high-speed railway, stone ballasts need to be filled between two lines to meet the slope-releasing regulations of the track bed, and 0.7m of stone ballasts cover the upper part of the central trench cover plate. Because of central apron ditch does not set up the inspection shaft, its inspection is overhauld and is carried out in combination with the maintenance of ballast bed, when a large amount of surface waters seeped down after the heavy rainfall of local surface, can be because construction such as stone tiny fragments of stone, coal, etc. is left over the thing and is blockked up, leads to the water cross-section of actual center ditch to be less than the design cross-section, causes central ditch drainage not smooth seriously to be obstructed, and the water level rises water and overflows the ballast bed, causes track structure circuit height to appear and changes, will cause major traffic accident.
