The corresponding combination of groove forms semicircular drainage hole.Surface water (such as rainwater) is flowed into the first holding tank 114 and by slope
In two holding tanks 116, roadbed is laterally then discharged by the drainage hole formed by permeable groove.
According to the present invention, the whole extended structure of cable trough 100 is determined according to the operating condition in practical section, is equipped with not
Same structure.Below according to the laying condition of different railway bed sections, it is discussed in detail and is layed in the cable trough of different sections of highway and prolongs
Stretch structure.
As shown in Figure 1, several cable trough ontologies 110 are arranged to along linear extension.In work progress, cable trough ontology 110
It is layed in the railway bed section of straightway, and the extending direction of the roadbed on downline road is laid with.
According to the present invention, as shown in figure 4, several cable trough ontologies 210 are arranged at least two sections of fan-shaped extensions.With fan
The cable trough ontology 210 of shape extended structure is used for the laying in corner location, in particular for the roadbed section of 90 ° of corners.Cable trough
Ontology 110 includes at least two section slot section units 201.Preferably, cable trough ontology 210 is configured with two sections 45 ° of slot section list
Member 201 is formed by connecting, and two section slot section units, 201 assembly connects and forms the cable trough 200 with 90 ° of corners.
Of course it is to be understood that cable trough 200 also can be configured to be formed by connecting by 30 ° of slot section unit 201, to pass through
The assembled connection of three sections of groove section unit 201 forms the cable trough 200 with 90 ° of corners.Of course it is to be understood that cable trough can be with root
Factually the corner demand in border section is configured to the slot section unit of other angles, or turns needed for being formed by several slot section unit splicings
The cable trough in angle section.
According to the present invention, at least partly there is the gradient to extend as shown in figure 5, several cable trough ontologies 310 are arranged to, and electricity
The extension gradient of cable slot 300 is determined according to the drainage grade of the surface layer of subgrade bed of the roadbed section in actual condition.Cable trough ontology
300 gradient for example may be provided in the range of 2%-5%.To roadbed, access or outgoing cable above and below some needs with
And the location of the gradient is encountered, it needs to carry out transition laying using the acclive cable trough 300 of tool.
In the present embodiment, cable trough ontology 300 includes two sections of sub- cable troughs 301 connected at an angle, two cross-talks
The connection of cable trough 301 forms certain gradient to adapt to the construction with gradient location.In one embodiment, sub- cable trough
Integral molding between 301.
The acclive structure of this tool of cable trough 300 can be applicable in the laying of Special Roadbed section, to improve
The applicability of cable trough 300.
According to the present invention, cable trough is made of glass steel material, and the inner structure size of cable trough is according to electric power slot
It is required with the actual size of signal of communication slot to determine.In one embodiment, cable trough should be prefabricated using batch production.This
Outside, it is contemplated that the current of maintenance personnel requires, and the passage characteristic value of load of cable trough takes 3kN/m2 evenly load.
The structure of cable trough according to the present invention for railway bed is simple, is adapted to the company of connection with card slot using protrusion
Mode is connect, assembly is easy to connect, and installation effectiveness is high, and structure, cross dimensions and sealing performance by optimizing cable trough,
Effectively increase the overall performance of cable trough.Meanwhile in conjunction with number of cables and requirement, plurality of specifications cable flute profile is provided
Formula, it is adaptable so as to be suitable for having a variety of special operation condition sections such as the gradient or corner, it can effectively avoid space
Waste.In addition, the cable trough can be improved water-inlet-proof and drainability, cable trough is effectively prevented during construction and operation
Subgrade drainage and stabilization are impacted, to reduce the generation of subgrade defect, improve the Service Environment of cable, is ensured
Service life and the railway operation safety of cable.
Finally it should be noted that the foregoing is merely the preferred embodiments of the invention, do not constitute to the present invention
Any restrictions.Although referring to foregoing embodiments, invention is explained in detail, for the technology of this field
