Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the vertical ground level in cable sand pit in the utility model；
Fig. 2 is the attachment structure schematic diagram of the power transformation station cable poling turning position in the utility model.
Specific embodiment
The utility model embodiment provides a kind of connecting node of power transformation station cable poling turning position, below in conjunction with
Figure of description is illustrated the preferred embodiment of the utility model, it should be understood that preferred embodiment described herein is only
For instruction and explanation of the utility model, it is not used to limit the utility model.And in the absence of conflict, in the application
Embodiment and embodiment in feature can be combined with each other.
Due to turning of cable radius limit, need by coating steel pipe according to turning of cable radius bend l-shaped, a part with
Original horizontally disposed water gas pipe connects, and is embedded in ground end, and another part vertically extends ground, electrical with needing to connect
Equipment connects；But electrical equipment, after civil construction, such civil engineering is completed preceding just it needs to be determined that good coating steel pipe elevates above the soil
Accurate location, to connect with other power equipments, working procedure causes that cable pipe positioning is inaccurate, and gap is biggish also
It needs to do over again.
Refering to fig. 1 and shown in Fig. 2, a kind of connecting node of power transformation station cable poling turning position, comprising: electrical equipment
The first coating steel pipe 1 is connected below cable connection port, which is arranged perpendicular to ground, and ground is protruded into bottom end
Below face, which is placed in cable sand pit 4；With ground level and the second coating steel pipe located underground
2, one end is protruded into cable sand pit 4, and the second coating steel pipe 2 protrudes into the one end in cable sand pit 4 and the first coating steel pipe 1 protrudes into cable
The one end in sand pit 4 is connected by metal hose 3；Fine sand 5 is filled in cable sand pit 4.The cable sand pit 4 uses machine brick masonry, electricity
Cement sand bed is arranged in 4 inner surface of cable sand pit and outer surface.First coating steel pipe 1, metal hose 3 and the second coating steel pipe 2
Form L-type, internal cabling.Sand pit is protruded into second coating steel pipe one end, and the other end protrudes into cable duct 6；It is embedded in the gold in sand pit
When belonging to 3 number of hose more than or equal to 3, a length of 1300mm in cable sand pit 4, width 740mm；It is embedded in the number of metal hose 3 in sand pit
When mesh is less than 3, a length of 740mm in cable sand pit 4, width 640mm.
Specifically, being positioned according to electric appliance general layout to sand pit, in electrical equipment cable connection port, downward vertical is buried
Cable sand pit 4 is set at pipe；Then according to the quantity of cable pipe, i.e., the first coating steel pipe 1, metal hose in the utility model
3 and second quantity of pipeline that forms of coating steel pipe 2, and according to the size of electrical equipment cable connection port, determine husky
Size is cheated, when the number of cable pipe is more than or equal to 3, using A type cable sand pit 4；When the number of cable pipe is less than 3, using B
Type cable sand pit 4；4 size of A type cable sand pit: 1300 × 740 × H (long × wide × deep)；4 size of Type B cable sand pit: 640 ×
740 × H (long × wide × deep).Two kinds of sand pit depth are advisable by turning of cable radius is met.The production method in sand pit: M5 water is used
Cement mortar builds M7.5 machine brick, uses 1:2 cement sand plaster 20mm thick inside and outside sand pit.Fine sand 5 is inserted after cable laying.
To prevent cable in sand pit, can be in sand pit by the cable pipe and attachment of the flat laying of telluric water with the sedimentation of fine sand 5
Foundation of civil work is reliably connected.The cable pipe and ground vertical run laid is put down in sand pit using metal hose 3 and telluric water
Cable pipe connection.According to the requirement of the outside diameter of cable and turning radius, the outer diameter and length of reasonable selection metal hose 3, metal
The internal diameter of hose 3 is slightly larger than the first coating steel pipe 1 and the second coating steel pipe 2.It, can using the good turning performance of metal hose 3
Meet the turning radius requirement of different cables.Over ground installation cable pipe cooperation electrical equipment connectivity port, definitely on
The positioning of poling, the metal hose 3 in ground need to be adjusted flexibly according to laying, do not limit civil construction.
