Abstract
The utility model discloses a sepiolite cement cable duct that is a pipe made of the mixture of sepiolite and cement. The outer surfaces of two ends of the pipe are provided with connecting ends, the external diameters of which are less than the diameter of the middle part of the pipe. The sepiolite cement cable duct has the advantages of low cost, light weight, high strength and corrosion resistance. As connecting ends with comparatively smaller diameter are arranged at the two ends, different cable ducts can be connected by connecting pipes, therefore no gaps exist between different cable ducts and connection is firm with good sealing performance. Combined with sepiolite external stent with rubber seal ring, the sealing performance of the utility model is better; when in use, the sepiolite cement pipe is only needed to be inserted in the external stent, which is very convenient.
Description
Technical field
The utility model relates to a kind of cable tube, is at underground used outer protection tube with cable burial.
Background technology
Cable tube be a kind of with cable laying at underground used protection tube, present cable tube is generally pipe of cement or metal tube, adopts metal tube, cable tube is perishable, influences its useful life, and the cost height; Adopt pipe of cement, because butt joint during different pipe of cement two ends has big slit between the pipe of cement, make cement cable tube junction can not form good sealing, easily cause the infiltration phenomenon, and pipe of cement is frangible, weight is heavier.
The utility model content
The purpose of this utility model be to provide a kind of solid firmly, the cable tube of light, the long service life of good airproof performance, weight.
In order to achieve the above object, the utility model adopts following technical scheme: the pipe of sepiolite cement cable tube for making by sepiolite and cement mixing, at pipe two ends outer surface car link is arranged, and the external diameter of link is less than the diameter at pipe middle part.
Can there be outer groove the end of above-mentioned pipe link by car.
Described sepiolite cement cable tube also comprises a round jacket pipe that connects different pipes, and outer tube is a sepiolite pipe of cement, and there are two annular grooves at outer tube inner surface two ends, and sealing ring is arranged in the groove.
Above-mentioned sealing ring can be rubber seal.
Can there be internal groove at above-mentioned outer tube two ends.
This sepiolite cement cable tube has that cost is low, in light weight, intensity is high and corrosion resistant advantage, owing to the less link of diameter is arranged at the two ends car, can different cable tubes be coupled together by tube connector, making between the different cable tubes does not have the slit, it is connected firmly and good airproof performance.With the sepiolite outer tube combination of band rubber seal, its sealing effectiveness is better, and sepiolite cement pipe is inserted in the outer tube when using and get final product, and is very easy to use.
Description of drawings
Fig. 1 is the preferred embodiment structure chart of sepiolite cement cable tube of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and better embodiment sepiolite cement cable tube of the present utility model is described further.
As shown in Figure 1, sepiolite cement cable tube is made of pipe 1 and outer tube 2, and a part is gone by car in the two ends of pipe 1, and the external diameter at two ends is diminished becomes link 4, and at the end of the link 4 car groove 5 of going out.The external diameter of the outer tube of being made by sepiolite cement 2 is greater than pipe 1, inner surface at outer tube 2 has the bipassage ring connected in star, be embedded with two rubber seal 3 at annular groove, rubber seal 3 is tight with the clearance seal of 2 of sepiolite cement pipe 1 and outer tubes, makes it be difficult for infiltration; Outer tube 2 two ends cars have internal groove.It is very easy that this structure makes this sepiolite cement cable tube install, as long as outer tube 2 is enclosed within on the link 4 of pipe 1, another pipe 1 is inserted outer tube 2 interior getting final product, because groove outside outer tube 2 two ends have, there is internal groove at pipe 1 two ends, make to become convenient easy when pipe 1 is inserted inner sleeve 2.
Claims (5)
