Abstract

The utility model relates to a ballastless track basement drainage system. The groundwater infiltration can result in the inverted arch to be packed and ballastless track binding site appearance cavity in the ballastless track tunnel, causes the ballastless track fracture, sinks. The utility model discloses setting up the inverted arch in inverted arch top and filling, the inverted arch is filled the surface and is set up water drainage tank at the bottom of the horizontal ballastless track, and the water drainage tank top is ballastless track bed course and ballastless track in proper order at the bottom of the ballastless track, water drainage tank stretches out at both ends the inverted arch packing face outlet of downward sloping at the bottom of the ballastless track, inserts in the tunnel lateral sulcus of inverted arch top both sides, at the bottom of the ballastless track water drainage tank to set up the construction joint that position and inverted arch filled corresponding. The utility model relates to a time remove inspersed groundwater, has effectually prevented that groundwater from getting into the inverted arch and filling and ballastless track binding site, and then has prevented the emergence of ballastless track disease.

Description

A kind of non-fragment orbit substrate drainage system

Technical field

The utility model belongs to traffic tunnel field of engineering technology, is specifically related to a kind of non-fragment orbit substrate drainage system.

Background technology

Adopt in the tunnel of non-fragment orbit, a kind of Major Diseases is the infiltration of underground water, inverted arch is caused to be filled and non-fragment orbit binding site appearance cavity, cause non-fragment orbit to ftracture, sink, the main cause of this disease is exactly fail to be drained by the ponding of binding site in time, under the impact of train, the long-term erosion of the concrete of binding site is caused to occur cavity.

Summary of the invention

The purpose of this utility model is to provide a kind of non-fragment orbit substrate drainage system, stops the generation of non-fragment orbit disease.

The technical scheme that the utility model adopts is:

A kind of non-fragment orbit substrate drainage system, is characterized in that:

Above inverted arch, arrange inverted arch fill, inverted arch is filled surface and is arranged rhone at the bottom of horizontal non-fragment orbit, is followed successively by non-fragment orbit bed course and non-fragment orbit above rhone at the bottom of non-fragment orbit;

Rhone two ends at the bottom of non-fragment orbit are stretched out downward-sloping inverted arch and are filled face spilled water hole, access in the tunnel lateral sulcus of both sides above inverted arch.

The setting position of rhone at the bottom of non-fragment orbit is corresponding with the constuction joint that inverted arch is filled.

Rhone at the bottom of non-fragment orbit is rectangular channel, and in tunnel, alignment both sides have the weathering of 1%.

At the bottom of non-fragment orbit, rhone end face is coated with cover sheet, is plank or steel plate.

The utility model has the following advantages:

The utility model is filled constuction joint position at inverted arch and is arranged rhone, the underground water infiltrated is drained in time from constuction joint, stops underground water and is retained in inverted arch filling and non-fragment orbit binding site for a long time, reduce railway roadbed Base pond odds.The utility model structure is simple, and constructability is safe and reliable, improves the safety of tunnel operation.

Accompanying drawing explanation

Fig. 1 is layout plan of the present utility model.

Fig. 2 is I-I sectional drawing in Fig. 1.

In figure, 1-inverted arch, 2-inverted arch is filled, 3-non-fragment orbit, 4-non-fragment orbit bed course, rhone at the bottom of 5-non-fragment orbit, and face spilled water hole filled by 6-inverted arch.

Detailed description of the invention

Below in conjunction with detailed description of the invention, the utility model is described in detail.

A kind of non-fragment orbit substrate drainage system that the utility model relates to, inverted arch is set above inverted arch 1 and fills 2, inverted arch is filled 2 surfaces and is arranged rhone 5 at the bottom of horizontal non-fragment orbit, at the bottom of non-fragment orbit, rhone 5 is rectangular channel, be of a size of 5cm × 5cm(wide × dark), in tunnel, alignment both sides have the weathering of 1%.At the bottom of non-fragment orbit, rhone 5 end face is coated with cover sheet, wide 22cm, thick 1.5cm, is plank or steel plate.Non-fragment orbit bed course 4 and non-fragment orbit 3 is followed successively by above rhone 5 at the bottom of non-fragment orbit.Rhone 5 two ends at the bottom of non-fragment orbit are stretched out downward-sloping inverted arch and are filled face spilled water hole 6, adopt diameter to be the pvc pipe of 50mm, access in the tunnel lateral sulcus of both sides above inverted arch 1.At the bottom of non-fragment orbit, the setting position of rhone 5 is corresponding with the constuction joint that inverted arch fills 2.

During construction, first build inverted arch 1 and inverted arch filling 2, then according to operation construction ditch sidewall, press the pre-buried inverted arch of design attitude simultaneously and fill face spilled water hole 6.Rhone 5 at the bottom of non-fragment orbit starts to perform after tunnel ditch sidewall has all been constructed again, and rhone adopts cutting machine on-site cutting.Can construct non-fragment orbit bed course and non-fragment orbit in the constructed location of rhone.

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.
