Transformer station is because cable is more, the standing setting put crisscross cable duct and be used for cable.To avoid place rain
Water is flowed into cable duct ditch body, then usually sets cable duct and obtain about 100mm higher than ground level, and cable duct draws transformer station place
Some regions are divided.To avoid site rainwater from collecting in cable duct both sides, it is necessary to be set at the top of cable duct according to a determining deviation
Tank is crossed, the aqueduct bottom absolute altitude is the same as place ground elevation.But because transformer station place especially embankment region has sedimentation, make to cross
Groove bottom land is higher than the ground settled, causes the rainwater in subregion not drain smoothly, otherwise these rainwater cross flows
Under ooze, serious substation operation or other Geotechnical Problems can be caused.
Utility model content
The technical problem that the utility model solves is：There is provided one kind is not influenceed by solum settlement around embankment area cable duct
Cable duct structure.
The utility model is that technical scheme is used by solving above-mentioned technical problem：Including the electricity being embedded among soil layer
Cable ditch, the side wall of the cable duct are stretched out in outside soil layer, are provided between the cable duct outer wall and soil layer between open-top
Gap, permeable layer is filled with the gap, in addition to soakaway trench, the permeable layer are connected with the soakaway trench, the infiltration
Pipe is arranged in the permeable layer below the cable duct.
Further, several osculums inside the structure body of the cable duct by being arranged on the cable duct bottom wall
It is connected with the permeable layer.
Further, rhone is provided with the inner bottom surface of the cable duct, the rhone is walked along the cable duct
To setting, the osculum is arranged on the rhone, between several trends of osculum along the rhone are equidistant
Every setting.
Further, cable duct inner bottom surface of the rhone along its left and right sides moved towards is draining face, the draining
Face by it close to the rhone side be inclined upwardly.
Further, the permeable layer is metalling.
Further, the contact surface being filled between permeable layer and the soil layer in the gap at left and right sides of the cable duct is set
The gradient is equipped with, on the section that the cable duct moves towards, the contact surface is started to away from the electricity from its bottom
The direction of cable ditch tilts.
The beneficial effects of the utility model are：The cable duct structure provided by the utility model for having drain function concurrently solves
Solum settlement around embankment area cable duct is so that the problem of part rainwater can not discharge, and reduce rainwater flows through path,
So as to improve drainage efficiency, and incorporate the pit of cable duct and drainpipe, enable workmen excavate simultaneously cable duct and
The pit of drainpipe, reduce engineering excavation amount and pit bank protection amount.

Embodiment
The cable duct structure for having drain function concurrently to the utility model below in conjunction with accompanying drawing describes in detail.
As shown in figure 1, the utility model has the cable duct structure of drain function concurrently, it includes being embedded among soil layer 1
Cable duct 2, the side wall of the cable duct 2 are stretched out in outside soil layer 1, are opened between the outer wall of cable duct 2 and soil layer 1 provided with top
The gap put, permeable layer 3 is filled with the gap, in addition to soakaway trench 4, the permeable layer 3 are connected with the soakaway trench 4
Logical, the soakaway trench 4 is arranged in the permeable layer 3 of the lower section of cable duct 2.
The utility model is filled with permeable layer 3 on the periphery of cable duct 2, the rainwater in place when overflowing to permeable layer 3,
I.e. speed is penetrated into permeable layer 3, is discharged so as to be flowed into by its deadweight in the soakaway trench 4 being connected with permeable layer 3.This reality
With Novel photo compared with traditional mode, solve what the sedimentation of the surrounding soil layer 1 of embankment area cable duct 2 can not discharge down to part rainwater
Problem, and reduce rainwater flows through path, so as to improve drainage efficiency, and incorporates the pit of cable duct 2 and drainpipe,
Workmen is excavated the pit of cable duct 2 and drainpipe simultaneously, reduce engineering excavation amount.Wherein, present embodiment is worked as
In, soakaway trench 4 is draining floral tube, and in other embodiment, soakaway trench 4 is french drain.
Among above-mentioned embodiment, cover plate 8 is generally provided with the top of cable duct 2 to cover rainwater, but in part
The larger region of precipitation, have a small amount of rainwater and enter in cable duct 2.So it is preferred that, among present embodiment,
Pass through several osculums 5 being arranged on the bottom wall of cable duct 2 and the permeable layer 3 inside the structure body of the cable duct 2
It is connected.The osculum 5 being arranged at into the rainwater in cable duct 2 on the bottom surface of cable duct 2 is discharged into permeable layer 3 rapidly.
In addition, to accelerate the drainage speed in the ponding in cable duct 2, whole 2 overall drainage performance of cable duct is improved, avoids cable
The discrepant situation of different parts drainage performance of ditch 2, among present embodiment, the row of being provided with the inner bottom surface of the cable duct 2
Tank 6, the rhone 6 are moved towards to set along the cable duct 2, and the osculum 5 is arranged on the rhone 6, some
The individual osculum 5 is set along the equi-spaced apart of moving towards of the rhone 6.
On the basis of above-mentioned embodiment, to improve cable duct 2 to remaining in the discharge capacity of its internal ponding, keep away
Exempting from the remaining of cable duct 2 has ponding, among present embodiment, bottom in cable duct 2 of the rhone 6 along its left and right sides moved towards
Face is draining face 7, the draining face 7 by it close to the side of rhone 6 be inclined upwardly.
Among above-mentioned embodiment, permeable layer 3 can use the permeable materials such as weaving material to be made, and be used as preferred side
Formula, among present embodiment, the permeable layer 3 is metalling.Using metalling as permeable layer 3, swelled ground can be effectively reduced
The detrimental effects such as the expansive force in area, the frost heave of Frozen Ground Area, and the sedimentation of earthen fill zone and Soft Soil Area can be reduced.
On the basis of above-mentioned embodiment, the permeable layer 3 and soil that are filled in the gap of the left and right sides of cable duct 2
Contact surface between layer 1 is provided with the gradient, and on the section that the cable duct 2 moves towards, the contact surface is by its bottom
Portion starts to tilt to the direction away from the cable duct 2.Wherein, as shown in figure 1, the left and right sides of cable duct 2 refers to walk along it
To the left and right sides.To ensure construction safety, in construction, when excavation exceedes certain depth or embankment exceedes certain altitude,
The contact surface at its edge should have certain gradient, prevent Tu Bi from caving in.
