The utility model discloses a kind of cable protecting device suitable for karst area, the cable protecting device is in series by more hollow tubes, and the hollow tube is made up of inwall, outer wall and inner chamber, it is characterised in that：The inwall is made from a different material respectively with outer wall, it is bonded to one by binding agent, described hollow tube one end is provided with tenon, the other end is provided with matched groove, tenon connects with engagement, the inwall is made by macromolecule polymer material, and the outer wall is made by exotic material.It using structure of the present utility model, can not only play a part of protecting high temperature, also make it that transport, installation and the dismounting of cable protecting device, maintenance are more convenient, accelerating construction progress, reach the installation of standardization, safeguard, greatling save time and cost.
Description
Technical field
Construction installation field, specifically a kind of protection device suitable for pre-buried cable are the utility model is related to, it is especially suitable
Protection for the pre-buried cable in karst area.
Background technology
Cable for building takes pre-buried default mode mostly, and its is buried in underground easily corrosion and deformation for a long time, spy
It is not in karst area, due to underground water high temperature erosion, is easily destroyed cable.The main function of cable protecting device is to prevent electricity
Cable is destroyed and causes short circuit accident, so as to cause other security incidents.In karst area, due to high temperature karst material it is long when
Between corrode, traditional cable protection pipe be very easy to destroy.
Utility model content
A kind of the problem of the purpose of this utility model is in order to overcome above-mentioned technology to exist, there is provided electricity suitable for karst area
Cable protection device, it can effectively prevent the high temperature of cable.Its is simple in construction, and making material cost is low, especially suitable for rock
Molten regional cable protection.
Technical scheme is used by the utility model：
A kind of cable protecting device suitable for karst area, the cable protecting device connected by more hollow tubes and
Into the hollow tube is made up of inwall, outer wall and inner chamber, it is characterised in that：The inwall is with outer wall respectively by different materials system
Into, be bonded to one by binding agent, described hollow tube one end is provided with tenon, and the other end is provided with matched groove, tenon with
Engagement connects.
The inwall is made by macromolecule polymer material.
The outer wall is made by exotic material.
Further, the macromolecule polymer material is in polyvinyl chloride, polytetrafluoroethylmaterial material, Kynoar
One or more of combinations.
Further, reinforcing fiber can be also included in the macromolecule polymer material.
Further, the reinforcing fiber is selected from mineral fibres, glass fibre, basalt fibre, carbon fiber, graphite fibre
In one or more of combinations.
Further, the exotic material is one or more of in mullite, clay, quartz, aluminum oxide
Combination.
In use, by several hollow tube joggles together, it is possible to meet the length of cable.A piece hollow tube is provided with convex
Together with one end of tenon with another hollow tube sets reeded one end joggle.
Using structure of the present utility model, it can not only play a part of protecting high temperature, also cause cable protecting device
Transport, installation and dismounting, maintenance are more convenient, accelerating construction progress, reach the installation of standardization, safeguard, greatling save
Time and cost.
Brief description of the drawings
Fig. 1 is the cross-sectional view of the utility model hollow tube.
Fig. 2 is the scheme of installation of the utility model cable protecting device.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, cable protecting device of the present utility model is in series by more hollow tubes, the hollow tube is by interior
Wall, outer wall and inner chamber composition, it is characterised in that：The inwall is made from a different material respectively with outer wall, is bonded by binding agent
Integrally, described hollow tube one end is provided with tenon, and the other end is provided with matched groove, and tenon connects with engagement.It is described
Inwall is made by macromolecule polymer material.The outer wall is made by exotic material.
In use, as shown in Fig. 2 when two cable protecting devices (10,10 ') series connection when, a cable protecting device one end
Tenon 16 and the groove 18 of another cable protecting device one end tightly engage, tongue-and-groove junction apply weather proofing sealant so that
It is completely embedded between attachment means, prevents Groundwater infiltration.
The inwall of either cable protection device is made by macromolecule polymer material.Polymeric material is selected from poly-
Vinyl chloride, polytetrafluoroethylmaterial material, one or more of combinations in Kynoar.High molecular polymer is prevented with stronger
Water-based energy and Corrosion Protection, Groundwater In The Karst Area mineralization rate is higher, easily corrodes cable.Further, polymeric material
In also include reinforcing fiber materials, reinforcing fiber materials are selected from mineral fibres, glass fibre, basalt fibre, carbon fiber, graphite
Fiber and its mixture.The inner surface of inwall 12 must be smooth, it is allowed to which cable and control line etc. easily pass through inner chamber 15.
The outer wall of either cable protection device is made by exotic material.The exotic material may be selected from not coming
Stone, clay, silica, any one or several materials of aluminum oxide and its mixture.Mullite is aluminosilicate clays mineral,
It is considered as particularly useful outer wall material.
By the exotic material of outer wall and the duplicate protection of the macromolecule polymer material of inwall, can not only play anti-
Protect the effect of high-temperature fusion, moreover it is possible to it is waterproof, corrosion-resistant, than traditional more convenient efficient economizing of steel pipe construction, also cable is protected
Transport, installation and dismounting, the maintenance of protection unit are more convenient, accelerating construction progress, reach the installation of standardization, safeguard, greatly
Time and cost are saved greatly.
