To drainage pumping plant, the center of second sheath 21 sets that there are one the second catch basins for being located at first 20 lower section of sheath
24, second catch basin 24 is connected to drainage pumping plant 15 by the second collector pipe 25 of both sides.
As a result, when needing draining, the moisture that top layer penetrates into outer shield portion 10 from tunnel internal soil layer can pass through outer drainpipe
Discharge, and the moisture in shield portion 12 equally can smoothly be discharged by internal drainage pipe in being penetrated into out of tunnel space, not only solve from
Soil horizon enters the problem of tunnel drainage, moreover it is possible to avoid entering interior shield portion from tunnel space after steam or humidity are excessive in tunnel
Drainage problem effectively increases the drain function and security performance of top layer, and supporting layer discharge structure passes through three layers of discharge structure
Setting, and gradual drainage performance is reduced from top to bottom in this three-decker, and moisture can successively enter, can preferably control
The successively infiltration of moisture processed, moreover it is possible to provide preferably buffering and support, while by the setting of two layers of catch basin, can smoothly by
The moisture of infiltration is expelled to pumping plant, in time discharges excessive moisture under the action of drainage pumping plant, and track support plate is avoided to occur
Support problem.
And in order to improve support strength, the cobble supporting layer 18 is additionally provided with more reinforcement support tubes 19, described to strengthen branch
Stay tube 19 can be made of steel pipe, and the lower end for strengthening support tube 19 can support in support plate, and upper end is supported in track support plate
16, the reinforcement support tube 19 can be arranged in cobble supporting layer 18 in array-like, as a result, under the action of support tube 19 is strengthened,
Track support plate 16 and rail 17 can obtain better support, and cobble supporting layer 18 can also carry out sufficient moisture discharge.
Wherein, the structure of the outer drainpipe 13 and internal drainage pipe 14 can be found in Fig. 2 and Fig. 3, can include by moulding material
Drainage conduit body 26 made of matter, the drainage conduit body thus with certain elasticity and intensity can preferably be arranged at top layer, in draining
Tube body 26 is equipped with multiple osculums 27, the unordered setting that the multiple osculum 27 can be longitudinally spaced, and each osculum 27 is equipped with
Netted filter layer 28 is avoided that sandstone soil enters osculum, moreover it is possible to beneficial to moisture it is effective by, for improve filtering and
Drainage performance, the filter layer 28 can be double-layer structure, comprising the metal filter screen 281 outside osculum 27 and positioned at row
Elastic filter screen 282 inside water hole 27, the hole of the metal filter screen 281 is more than the hole of elastic filter screen 282, this
Setting is the intensity higher due to metal filter screen 281, that is, ensure that the filtering support effect of metal filter screen 281, is effectively protected
The elastic filter screen 282 of shield is not destroyed.
Optionally, coarse sand filter layer can be equipped in first osculum 27, which is located at metal filtration
Between net and elastic filter screen.
Optionally, the structure of 23 and second collector pipe 25 of the first collector pipe can be similar with drainpipe, similary to wrap
Containing the tube body that catchments made of moulding material, equipped with multiple gully-holes, the multiple gully-hole was equipped with the tube body that catchments
Strainer, the filter screen can be made of metal, to provide preferable intensity and filtering drainage performance.
The present invention can provide extraordinary drainage performance, the either more area of precipitation still for subterranean tunnel as a result,
The smaller area of precipitation can be applicable in, even the very big area of precipitation, the moisture of top layer can by penetrate into after drainpipe compared with
Fast discharge, the moisture of bottom also can quickly be discharged by catch basin and collector pipe, and then quickly be arranged by drainage pumping plant
Go out outside tunnel.
Therefore, the advantage of the invention is that：
1st, draining is smooth, convenient for quickly discharging the moisture in tunnel, avoids the ponding in tunnel may；
2nd, it is applied widely, convenient for promoting on a large scale；
3rd, it is convenient to construct, and has good feasibility.
