The utility model relates to a high-toughness power cable protection tube. The cable tube solves the problems of low toughness, poor bending resistance and compression resistance of the existing cable protection tube. This kind of high toughness power cable protection tube includes a tube body, the outer wall of the tube body is provided with an epoxy resin layer, the inner wall of the tube body is provided with a graphite emulsion lubricating film layer, and the outer wall of the tube body is provided with several Metal strips; two adjacent metal strips are bound and connected by connecting ropes. The metal strips arranged longitudinally along the outer wall of the tube body of the high-toughness power cable protection tube described in the utility model can effectively improve the bending resistance of the cable tube and improve the compressive strength of the cable tube.
Description
Technical field
The utility model relates to the communications field, especially relates to a kind of high tenacity power cable protecting pipe.
Background technology
The power cable pipe has another name called electric power comb, cement cable tube etc.The outstanding feature of power cable pipe is that intensity is high, frictional resistance is little, higher by 40% than common tube intensity, the anti-folding load 〉=12000N of body, external pressure load 〉=15000N, can be used for various other road pavements of level uses, the frictional resistance of inwall and cable is little to be the outstanding advantages of power cable pipe, and its coefficient of friction＜0.35 is starkly lower than other classification cable tubes such as fiberglass, PVC.When logical cable, reduced the quantity of worker's well, reduced again project cost, increased cable pulling length.
Cable tube is embedded in underground, wears cable in it, mainly protects cable in use not by damages such as outside destroy, corrosive liquids infiltrations, therefore requires cable tube to have certain intensity, permeability resistance, resistance to compression and bend resistance performance; The existing cable pipe adopts cement to form the cable tube structure in mould, this cable tube toughness is lower, so in work progress, lay first one deck cement concrete ground, behind the tubing, lay cement concrete at pipe end face and side again, so that cable tube is enclosed in the structure of cement concrete, such cable tube is because the toughness of itself is low, and have in work progress, increase the construction of concrete foundation and seal, increased the expense of construction, long construction period.
Summary of the invention
The utility model technical issues that need to address are: in order to overcome the problem of above-mentioned middle existence, provide a kind of bend resistance and compressive property good, simultaneously can keep again the strong high tenacity power cable protecting pipe of existing cable pipe anti-permeability.
The technical scheme that its technical problem that solves the utility model adopts is: this kind high tenacity power cable protecting pipe comprises body; the outer wall of body is provided with epoxy resin layer; the inwall of described body is provided with the aquadag lubricant film layer, vertically is provided with some bonding jumpers along body on tube wall.
Further, described bonding jumper is along the uniform setting of body hoop, is provided with connection cord between two adjacent bonding jumpers and ties up connection.
The beneficial effects of the utility model are: bend resistance performance and compression strength that some bonding jumpers that vertically arrange along body on tube wall can the Effective Raise cable protection pipes, simultaneously along the uniform Position Design of body hoop, can avoid producing current vortex, thereby can not affect the electric property of cable in the cable protection pipe; Aquadag lubricant film layer in the inboard wall of tube body coating, when cable passes inboard wall of tube body, the aquadag lubricating film is understood stressed fracture and is produced slip plane, and these slip planes have changed the friction mode between inboard wall of tube body and the cable, thereby have reached the purpose of capable of reducing friction resistance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the overall structure cutaway view of a kind of high tenacity power cable protecting pipe described in the utility model;
Fig. 2 is the cross sectional representation of Fig. 1.
Accompanying drawing acceptance of the bid score state as follows: 1, body, 1-1, epoxy resin layer, 1-2, aquadag lubricant film layer, 1-3, bonding jumper.
Embodiment
Now by reference to the accompanying drawings 1 and Fig. 2 the utility model is described in further detail.This accompanying drawing is the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only shows the formation relevant with the utility model.
High tenacity power cable protecting pipe as depicted in figs. 1 and 2, comprise body 1, the outer wall of body 1 is provided with epoxy resin layer 1-1, the inwall of described body 1 is provided with aquadag lubricant film layer 1-2, when cable passes inboard wall of tube body, the aquadag lubricating film is understood stressed fracture and is produced slip plane, and these slip planes have changed the friction mode between inboard wall of tube body and the cable, capable of reducing friction resistance; Vertically be provided with some bonding jumper 1-3 at body 1 outer wall along body, can well improve bend resistance performance and the compression strength of cable tube, the tube wall other materials still can use refinforced cement, so that cable tube still has good permeability resistance.
Bonding jumper 1-3 is along the uniform setting of body 1 hoop, so that cable protection pipe is balanced in the bend resistance intensity of all directions, does not need travel direction to select during construction; Be provided with connection cord between two adjacent bonding jumper 1-3 and tie up connection, adopt rope to connect and to control the distribution of bonding jumper in tube wall, rope can be selected nylon rope, also can select not produce the nonmetallic materials of current vortex, makes in the cable tube and can not produce current vortex.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
