Power can make preferably to bond between the outer surface of aluminium-plastic tape 61 and the inner surface of inner sheath main body 62, while also make plastic-aluminum
Composite band 61 it is wrapped put up between obtain good adhesive property, make as a result, moisture along horizontal water conservancy diversion cable radial direction seep
The path entered in conductor 1 is completely blocked, to play excellent resistance effect.In the above-described embodiments, it is preferred that interior
The material of sheath body 62 is polyethylene or polyvinyl chloride, and the insulation performance of polyethylene and polyvinyl chloride is more excellent, can have been played
The insulation protection of effect.
In the embodiment shown in fig. 1, in order to prevent the corrosive substance in water by the gap between adjacent two steel wires
Generate corrosiveness in into horizontal water conservancy diversion cable and to structures such as internal conductors 1, it is preferred that adjacent two zinc-coated wires it
Between be filled with anti-corrosion material, in this way, further ensuring horizontal water conservancy diversion by filling anti-corrosion material between adjacent two steel wires
The corrosion resistance of cable.
In addition, the composition to anti-corrosion material is not specifically limited.Preferably, anti-corrosion material is pitch, and pitch has good
Cohesiveness, ageing resistance and waterproof and anticorrosion ability, and raw material is easy to get, is cheap, can effectively seal adjacent two it is zinc-plated
Gap between steel wire, and play preferably waterproof anti-corrosion performance.
In order to protect and fix armor 7, it is preferred that as shown in Figure 1, being extruded with oversheath 8 outside armor 7.In this way,
Under the extruding force effect of oversheath 8, armor 7 has been effectively secured to outside inner sheath 6, and oversheath 8 can be to armor 7
It plays a certain protective role, avoids in the transport or installation process of horizontal water conservancy diversion cable, damage armor 7.
In order to further increase the water pressure resistance performance of horizontal water conservancy diversion cable, it is preferred that the quantity of armor 7 be it is multiple, it is more
A armor 7 is set between inner sheath 6 and oversheath 8 along the radially superimposed of horizontal water conservancy diversion cable, in this way, passing through multiple armourings
Layer 7, further improves the water pressure resistance performance of horizontal water conservancy diversion cable.
Specifically, the quantity of armor 7 can be two, three or four etc., it is not specifically limited herein.But
In order to be reduced as far as the quantity of armor 7 under the premise of the water pressure resistance performance for water conservancy diversion cable of improving the standard, to reduce water
The structure complexity and diameter of flat water conservancy diversion cable, in favor of being installed in the limited deep-well in space, it is preferred that such as Fig. 1 institute
To show, the quantity of armor 7 is two, and the thickness of two layers of zinc-coated wire is smaller, it can be installed in the limited deep-well in space,
And it can guarantee the water pressure resistance performance of horizontal water conservancy diversion cable, while can be improved the tensile strength of horizontal water conservancy diversion cable.
When the quantity of armor 7 is two, it that is to say that horizontal water conservancy diversion cable has two layers of zinc-coated wire, two layers of galvanized steel
The tensile strength and yield strength of silk are respectively 345Mpa and 310 Mpa, at this point, strong in order to verify the tension of horizontal water conservancy diversion cable
Whether degree meets installation requirement, and the horizontal aerial weight of water conservancy diversion cable is usually 8.05kg/m, and weight in water is usual
For 5.70kg/m, entire well depth is 1000m, and the depth of water in well is 800m, and the spatial depth of side waterborne is 200m in well, thus may be used
To be calculated when installing horizontal water conservancy diversion cable to shaft bottom, the minimum installed load of horizontal water conservancy diversion cable: F=need to be supplied to
8.05 × 200 × 9.8+5.70 × 800 × 9.8=6.16 × 104N is further calculated and is shown that the horizontal water conservancy diversion cable is being installed
When the maximum Fracture Force that generates be 149.8KN, it can thus be seen that tensile strength of the maximum Fracture Force less than two layers of zinc-coated wire
And yield strength guarantees horizontal water conservancy diversion cable so can meet tension requirement well using two layers of zinc-coated wire armouring
Tensile strength.
The deep-well bore as locating for deep-well type vertical grounding electrode is smaller, is 380mm, and the diameter of lower half portion only has
320mm, therefore, in order to be installed in the lesser deep-well of this bore, it is preferred that the diameter of horizontal water conservancy diversion cable be 51~
57mm, the diameter of horizontal water conservancy diversion cable within this range when, the diameter of horizontal water conservancy diversion cable is moderate, can be in the limited depth in space
It is installed in well, and can satisfy the functional requirement of each structure inside horizontal water conservancy diversion cable.
It, can be using water shown in limited element analysis technique simulation drawing 1 for the water pressure resistance performance of water conservancy diversion cable shown in proof diagram 1
Variation of the flat water conservancy diversion cable under 800m hydraulic pressure is used first when using limited element analysis technique dummy level water conservancy diversion cable
CPS4R grid cell carries out grid dividing to the construction of cable, and the structure after division is as shown in Fig. 2, and to horizontal water conservancy diversion cable
Outer surface applies the hydrostatic pressure of 8Mpa for one week, that is to say the underwater pressure of 800m, at this point, the horizontal water conservancy diversion cable being calculated
Cross section structure change as shown in figure 3, referring to Fig. 3, the maximum radial decrement of horizontal water conservancy diversion cable is under 800m hydraulic pressure
4.53mm, the horizontal water conservancy diversion cable strain distribution map and stress envelope being calculated are respectively shown in Fig. 4 and Fig. 5, referring to figure
4, the maximum strain that the section of horizontal water conservancy diversion cable generates is 2.2 × 10-2, referring to Fig. 5, what the section of horizontal water conservancy diversion cable generated
Maximum stress is 42.1Mpa, the structure remained stable of horizontal water conservancy diversion cable, not up to water it can be seen from Fig. 3, Fig. 4 and Fig. 5
The performance boundary of each material in flat water conservancy diversion cable.It can thus be seen that the horizontal water conservancy diversion cable of the embodiment of the present invention can be resisted
The deep-water pressure of 8Mpa, the horizontal water conservancy diversion cable of the embodiment of the present invention can be in the deep underground works of 800m.
The embodiment of the present invention is also for a kind of deep-well type vertical grounding electrode, including feeds steel pipe and horizontal water conservancy diversion cable,
The feed steel pipe is vertically placed in deep-well, and the horizontal water conservancy diversion cable is horizontal water conservancy diversion described in any technical solution as above
