Cost.Cable trench is excavated again after the completion of roadbed filling, certain disturbance is caused to roadbed, destroys roadbed globality,
Gap after backfill between cable trough and roadbed is the weak link easily to seep water, and top moisture penetrates into cable trench bottom and such as can not
It excludes in time, will penetrate into roadbed and cause a series of subgrade defects, seriously affect roadbed working condition, and then influence column
Vehicle operation security, even if being laid with one layer of sand bedding course or blotter as drainage blanket in cable trench bottom, moisture also can not be complete
It is discharged outside bedding.
In order to reduce width of the subgrade surface, project cost is reduced, is avoided because excavating the weak infiltration formed after cable trough foundation pit
Position, the utility model provide a kind of novel railway cable trough structure type.Novel cable slot occupies less or even is not take up road
Base width does not excavate the roadbed for filling completion, avoids a series of diseases caused by moisture intrusion, has reduction road bed wide
Degree reduces Engineering Task amount, does not destroy roadbed globality, reduces the advantages that project cost, can be used in the roadbeds such as high-speed railway.
Utility model content
It is layed in road shoulder position to solve cable trough in the prior art, and is embedded in surface layer of subgrade bed, roadbed is increased
Face width and project amount, improve project cost；Cable trench is excavated again after the completion of roadbed filling, and roadbed is caused centainly
Disturbance, destroy roadbed globality, top moisture penetrates into cable trench bottom and can not such as exclude in time, causes a series of roadbeds
Disease seriously affects roadbed working condition, and then influences technical problems, the utility model such as train operation safety and provide a kind of electricity
Cable slot, is able to solve above-mentioned technical problem, has and reduces width of the subgrade surface, reduce project amount, reduce project cost, do not destroy road
Base integrality, the advantages that avoiding top moisture from entering bedding.
To achieve the above object, the technical solution adopted in the utility model are as follows:
A kind of cable trough, the cable trough ontology including cable trough bracket and above the cable trough bracket.
The cable trough includes cable trough bracket and the cable trough ontology above the cable trough bracket.So that described
Cable trough ontology is set to above the surface layer of subgrade bed, is reduced width of the subgrade surface and project amount, is reduced project cost.In roadbed
When filling certain elevation, after the completion of burying cable trough bracket or roadbed integral construction, then embedded cable trough bracket.It will not
Roadbed is caused to disturb, roadbed globality will not be destroyed, it is not easy to seep water.
Preferably, cover board is equipped with above the cable trough ontology.The design of the cover board can be convenient the inspection of later period cable
It repairs.
Preferably, the cable trough body bottom portion is provided with drain hole.
Preferably, position corresponding with the drain hole is equipped with drainage tube below the cable trough ontology.
After water leaking-in in cable trough ontology, it can be discharged by the drain hole of bottom, and then drained by drainage tube
The positions such as skeleton slope protection avoid water from directly being flowed down by the drain hole on cable trough ontology and wash out surface layer of subgrade bed.
Preferably, pan arrest is equipped between the cable trough ontology and the cable trough bracket.
Preferably, position corresponding with the drain hole is provided with through-hole on the pan arrest.
Preferably, the through-hole that the drainage tube top passes through on the pan arrest is connected with the drain hole.
The utility model has the following beneficial effects: the step of eliminating excavation pit, reduces workload, bedding ensure that
Integrality.Width of the subgrade surface is reduced, project cost is reduced.Moisture is avoided to enter by the gap between cable trough and foundation pit
It within bedding, causes to rise soil, the subgrade defects such as frost heave.Later maintenance, replacement are convenient, without excavating again, disturbing bedding.
