Description
Technical field
Technical field of civil engineering is the utility model is related to, particularly a kind of power cable comb laying structure.
Background technology
Continuous with national urbanization process promotes, and the development in city is getting faster, also more next for the demand of electricity consumption
It is higher, therefore, it is necessary to strengthen the construction of urban electric power power grid.The system of laying of power cable has a variety of, can be divided into direct burial, tunnel
Road formula, cable duct type, calandria, vertical shaft type, bridge, water-bed laying etc..Wherein cable duct bank laying is that cable laying exists
A kind of system of laying of the pre-plugged in the pipe of underground.Intersect commonly used in buried cable with highway, railway, buried cable
Pass through the more crowded locations such as house, square, frequent, the industrial and mining enterprises' subterranean corridor of traffic.Compared to other system of laying, comb
System of laying has the advantages that to be not easy by environmental damage, space is small, safety and stability, can effectively insect-pest, moisture-proof.It is but same
When, for cable duct bank system of laying there is also the shortcomings that poor radiation, this directly results in the current-carrying capacity of cable in the case of multiloop
Decline.
The content of the invention
The purpose of this utility model is to provide a kind of power cable comb laying structure, by improving comb laying knot
Structure, sets heat dissipation duct inside the left and right sides of concrete layer, improves the heat dissipation performance of concrete layer, improves cable load
Flow.
To realize above-mentioned technical purpose and the technique effect, the utility model discloses a kind of power cable comb
Laying structure, including cable tubing, pipe pillow, blinding layer, heat dissipation duct, ground wire, earthing pole and concrete layer, the basis
Bed course is arranged on comb laying structure bottom, and the cable tubing is set in the pipe pillow and is positioned over above blinding layer,
The ground wire is laid along cable tubing bottom, and the earthing pole is welded to connect with ground wire, and the pipe rests the head on periphery concrete
Layer encapsulating is tamped, and some heat dissipation ducts are set inside the left and right sides of the concrete layer.
Further, the cable tubing is single-wall corrugated pipe, thickness of pipe wall 5mm.
Further, the internal diameter in the heat dissipation duct is not more than the 1/4 of cable pipe internal diameter.
Further, back fill course is also set up at the top of the concrete layer, the thickness pavement of backfill is not less than
0.6m, driveway are not less than 0.7m.
Further, the ground wire uses 50x5 zinc-coated flat steel sheets.
Further, the earthing pole uses L50x5 Zinc-coated angle steels, length 1.5m.
The utility model has the advantages that：
A kind of power cable comb laying structure provided by the utility model, by inside the left and right sides of concrete layer
Some heat dissipation ducts are set, the heat dissipation performance of concrete layer is improved, improves current-carrying capacity of cable, and inside the left and right sides
Heat dissipation duct is set not weaken protective effect of the concrete layer to pipeline.Since cable pipeline needs to bear overburden layer and the external world
Additional loading, therefore should avoid setting heat dissipation duct inside both sides above and below concrete layer, in order to avoid influence cable pipeline load-bearing.Together
When, a kind of power cable comb laying structure provided by the utility model, by setting blinding layer, can prevent cable tubing
It is subjected to displacement and stress raisers phenomenon occurs, and sets pipe to rest the head on to fix tube layer and branch by longitudinally spaced appropriate spacing
Support.
Brief description of the drawings
Fig. 1 is the structure diagram of existing the utility model.
Critical piece symbol description:
1：Cable tubing, 2：Pipe is rested the head on, and 3：Blinding layer, 4：Heat dissipation duct, 5：Ground wire, 6：Earthing pole, 7：Concrete layer,
8：Back fill course.
Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.
It is a kind of power cable comb laying structure as shown in Figure 1, including cable tubing 1, pipe pillow 2, blinding layer 3, dissipates
Hot hole road 4, ground wire 5, earthing pole 6 and concrete layer 7.Blinding layer 3 is arranged on comb laying structure bottom.Cable tube is route
In overburden layer to be born and extraneous additional loading, it is therefore desirable to carry out based process to comb laying structure bottom, pass through setting
Blinding layer, can prevent that cable tubing is subjected to displacement and stress raisers phenomenon occurs.Cable tubing 1 is set in the pipe
In pillow 2 and it is positioned over above blinding layer 3.Set in the present embodiment using eight cable tubing, bilayer, four every layer
Stacked arrangement mode arranged side by side, in order to fix tube layer and support, longitudinally spaced appropriate spacing sets pipe to rest the head on.Pipe pillow spacing according to
Above pipeline earthing layer thickness and road surface bogie by when comprehensive load set.Ground wire 5 is applied along 1 bottom of cable tubing
If earthing pole 65 is welded to connect with ground wire, it is desirable to which all ironwares are connected with ground wire in pipeline, the Ω of ground connection internal resistance R≤10.
Pipe is rested the head on the encapsulating of 2 periphery concrete layers 7 and is tamped, and can effectively prevent external world, and can be effectively moisture-proof, and increase cable uses
Service life.Some heat dissipation ducts 4 are set inside the left and right sides of concrete layer 7, the heat dissipation performance of concrete layer is improved, improves electricity
Cable current-carrying capacity, and set heat dissipation duct not weaken protective effect of the concrete layer to pipeline inside the left and right sides.Due to
Cable pipeline needs to bear overburden layer and extraneous additional loading, therefore should avoid setting heat dissipation inside both sides above and below concrete layer
Duct, in order to avoid influence cable pipeline load-bearing.
Cable tubing 1 is single-wall corrugated pipe, thickness of pipe wall 5mm.Joint should be strictly aligned, and be covered with glue, prevent water
Permeate in inlet pipe.
The internal diameter in heat dissipation duct 4 is not more than the 1/4 of 1 internal diameter of cable tubing, and heat dissipation duct within this range can play
While heat dissipation effect, the compressive resistance of concrete layer is not destroyed.
The top of concrete layer 7 also sets up back fill course 8, and the thickness pavement of backfill is not less than 0.6m, and driveway is not small
In 0.7m.
Ground wire 5 uses 50x5 zinc-coated flat steel sheets.
Earthing pole 6 uses L50x5 Zinc-coated angle steels, length 1.5m.
The above, is only the preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.
