Abstract
The utility model relates to a han qu tunnel drainage system. Freezing all appears in severe cold area tunnel lateral sulcus and central ditch easily, freezes threat driving safety after leading to swelling to the railway roadbed the ditch in. The utility model discloses a drainage lateral sulcus, bury central ditch and drainage blind pipe deeply, the drainage lateral sulcus vertically sets up both sides in the tunnel, and the outlet is stretched out to railway roadbed side wall body to longitudinal separation, burying central ditch deeply and vertically setting up in the inverted arch below, the lower part sets up in C20 concrete foundation, and upper portion sets up the seepy material, the anchor of drainage blind pipe hoop is in the lining cutting back at tunnel arch wall position, and the seepy material is stretched into to the bottom. The utility model discloses set up the central ditch of burying deeply in tunnel invert below, the center is buried the ditch deeply and is located below the depth of freezing, the phenomenon of freezing can not appear, and tunnel lining ponding behind one's back directly emits into in the center buries the ditch deeply through the blind pipe, no longer emit into the tunnel lateral sulcus in, can prevent that the emergence of driving safety accident from appearing threatening after frozen in lateral sulcus or central ditch.
Description
Technical field
The utility model belongs to traffic tunnel field of engineering technology, is specifically related to a kind of tunnel in cold area drainage system.
Background technology
Drainage system in current tunnel is primarily of draining blind pipe, draining lateral sulcus, Central drain composition, drainage procedure is as follows: tunnel lining ponding behind enters in tunnel lateral sulcus by blind pipe, then by pre-buried gutter, the water of lateral sulcus is introduced Central drain, finally by Central drain, water is drained into outside hole.But in severe cold area, because temperature is lower, freezing all easily appears in lateral sulcus and Central drain, cause the swelling in ditch to freeze to railway roadbed, threaten traffic safety.In addition, if the construction quality of Central drain does not pass a test, be easy to cause tunnel to be filled and occur disease, affect railway roadbed further and produce disease, can traffic safety be threatened equally.
Summary of the invention
The purpose of this utility model is to provide a kind of tunnel in cold area drainage system, prevents the tunnel ditch of severe cold area from occurring disease.
The technical scheme that the utility model adopts is:
A kind of tunnel in cold area drainage system, is characterized in that:
Comprise draining lateral sulcus, buried Central drain and draining blind pipe;
Draining lateral sulcus is longitudinally arranged at both sides in tunnel, and longitudinal separation stretches out spilled water hole to railway roadbed side wall body;
Buried Central drain is longitudinally arranged at below inverted arch, and bottom is arranged at C20 concrete foundation, and top arranges seepy material;
Draining blind pipe hoop is anchored at the lining cutting at tunnel arch wall position behind, and seepy material is stretched in bottom.
Buried Central drain is reinforced concrete sewer pipe.
Draining blind pipe adopts anchor studs and splash guard fillet to be anchored at arch wall position and just props up on face, and anchoring spacing is about 50cm;
Draining blind pipe has PVC protection tube at inverted arch position cover, and termination is directly introduced in the Deeply buried ditch seepy material of center.
Seepy material is made up of the small crushed stone of φ 0.4-0.6cm, the gravel pebbles of φ 3-5cm, the block stone of φ >=15cm, and backfill order is followed successively by small crushed stone, gravel pebbles, block stone from top to bottom.
Draining blind pipe is HDPE mono-shell hole-punched bellows.
The utility model has the following advantages:
The utility model eliminates traditional Central drain, is provided with center Deeply buried ditch below tunnel invert, and center Deeply buried ditch is positioned at below the depth of frost penetration, there will not be icing phenomenon.Tunnel lining behind ponding directly enters in the Deeply buried ditch of center by blind pipe, and no longer enter in tunnel lateral sulcus, tunnel lateral sulcus is the row's of being used for railway roadbed water for cleaning only.Adopt this drainage system, can prevent lateral sulcus or Central drain from occurring the rear generation threatening traffic safety accident of freezing.
Accompanying drawing explanation
Fig. 1 is cross-sectional drawing of the present utility model.
In figure, 1-draining lateral sulcus, the buried Central drain of 2-, 3-draining blind pipe, 4-spilled water hole, 5-reinforced concrete sewer pipe, 6-C20 concrete foundation, 7-seepy material, 8-PVC protection tube.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
A kind of tunnel in cold area drainage system that the utility model relates to, comprises draining lateral sulcus 1, buried Central drain 2 and draining blind pipe 3.
Draining lateral sulcus 1 row of being mainly used to tunnel railway roadbed ponding, be longitudinally arranged at both sides in tunnel, longitudinal separation stretches out spilled water hole 4 to railway roadbed side wall body.
Ponding after the lining cutting of buried Central drain 2 row of being used for is reinforced concrete sewer pipe 5, and be longitudinally arranged at below inverted arch, bottom is arranged at C20 concrete foundation 6, and top arranges seepy material 7.Seepy material 7 is made up of the small crushed stone of φ 0.4-0.6cm, the gravel pebbles of φ 3-5cm, the block stone of φ >=15cm, and backfill order is followed successively by small crushed stone, gravel pebbles, block stone from top to bottom.
Draining blind pipe 3 is HDPE mono-shell hole-punched bellows; hoop is anchored at the lining cutting at tunnel arch wall position behind; adopting anchor studs and splash guard fillet to be anchored at arch wall position just props up on face; anchoring spacing is about 50cm; at inverted arch position, cover has PVC protection tube 8, and termination is directly introduced in center Deeply buried ditch seepy material 7.
During construction, be first anchored on a first face with anchor studs and splash guard fillet by draining blind pipe 3, center Deeply buried ditch 2 of then constructing, the draining blind pipe 3 at inverted arch position overlaps PVC protection tube 8 after-pouring in concrete.
Content of the present utility model is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading the utility model manual to any equivalence that technical solutions of the utility model are taked, is claim of the present utility model and contains.
