Abstract
The utility model belongs to high voltage electricity facility field especially relates to a linear ground structure of steel pipe pole, include on the ground connection owner muscle of steel pipe pole column foundation that the welding lead connects, set up the vertical soil layer that inserts of a plurality of galvanized steel pipe in the both sides of steel pipe pole column foundation according to the same interval, between the galvanized steel pipe through the welding of zinc -plated round steel together, be connected to the pigtail splice through zinc -plated round steel on, zinc -plated round steel is between 0.6-1m apart from the distance on ground. The utility model discloses changing traditional radial ground connection along the linear ground connection on planning way into, having reduced area, it is respond well conveniently to be under construction. Effectively utilize the intensive reinforcing bar net of arranging in the bored concrete pile basis, increased the same area of contact greatly of earth connection, fine reduction ground resistance.
Description
Technical field
The utility model belongs to high-tension electricity facility field, particularly relates to the linear ground structure of a kind of steel pipe pole.
Background technology
In traditional earth electrode design of steel pipe pole, mainly utilize the ground structure of the vertical and radial horizontal laying of band steel of angle steel, but investigate from transmission line ruuning situation, this ground connection is not also suitable for steel pipe pole for planning the feature of curb line, in order to reduce the impact on existing road surface and neighbouring pipeline, usually cause ground lead to arrange narrow, earthing effect is undesirable, and earth resistance of power transmission line is difficult to meet technical requirement.Therefore, be badly in need of a kind of effective ground structure of design, make it be applicable to the steel pipe pole circuit arranged along planning road.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of steel pipe pole linear ground structure, solves the present situation that traditional arrangement does not meet steel pipe pole planning both sides, road construction, increases floor space, the destruction of road pavement and periphery pipeline.
The utility model realizes like this, the linear ground structure of a kind of steel pipe pole, welding lead joint on the main muscle of ground connection being included in steel pipe pole column foundation, in the both sides of steel pipe pole column foundation, multiple coating steel pipe is set according to same intervals and vertically inserts soil layer, welded together by galvanized steel bar between coating steel pipe, be connected on pigtail splice by galvanized steel bar, the distance on galvanized steel bar distance ground is between 0.6 ~ 1m.
Further, interval 5 ~ 6m between described coating steel pipe.
Further, the length of described coating steel pipe is 2 ~ 3m.
Further, the interior diameter of described coating steel pipe is 5 ~ 7cm.
Further, the diameter of galvanized steel bar is 1.2 ~ 3cm.
Compared with prior art, beneficial effect is the utility model: traditional radial ground connection is changed into the linear ground connection along planning road by the utility model, and decrease floor space, convenient construction is respond well.
Efficiently utilize the bar-mat reinforcement of intensive layout in bored concrete pile foundation, increase earth connection with contact area greatly, well reduce earth resistance.
The vertical layout of Appropriate application coating steel pipe, changes over the earthing mode utilizing merely galvanized steel bar, and coating steel pipe is compared with galvanized steel bar, and large with contact area greatly, be easy to buried construction, earthing effect is good.
The linear ground connection of steel pipe pole has good electric conductivity, can arrange along planning road neatly, reduce floor space, bar-mat reinforcement in original bored concrete pile foundation is applied to ground connection, creatively use coating steel pipe as grounding assembly, utilize the increase of vertical contact area to reduce the large problem of traditional approach floor space.
Accompanying drawing explanation
Fig. 1 is the device structure schematic diagram that the utility model embodiment provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1
See Fig. 1, the linear ground structure of a kind of steel pipe pole, welding lead joint 6 on the main muscle 5 of ground connection being included in steel pipe pole column foundation 1, in the both sides of steel pipe pole column foundation 1, multiple coating steel pipe 4 is set according to same intervals and vertically inserts soil layer, welded together by galvanized steel bar 3 between coating steel pipe 4, be connected on pigtail splice 6 by galvanized steel bar 3, the distance on galvanized steel bar distance ground 2 is between 0.6m.Interval 5m between coating steel pipe 4.The length of coating steel pipe 4 is 2m.The interior diameter of described coating steel pipe 4 is 5cm.The diameter of galvanized steel bar 3 is 1.2cm.
When foundation construction, need the reserved pigtail splice welded with main muscle outside basis, simultaneously along planning road trend, on basis two, linear excavation earth connection arranges ditch, with the spacing of 5m, the coating steel pipe that 2m is long is vertically inserted in soil layer, finally utilize galvanized steel bar pigtail splice, the main muscle of ground connection, coating steel pipe to be welded together.First such structure efficiently utilizes bar-mat reinforcement intensive in bored concrete pile, utilizes enlarge active surface to reduce resistance, secondly utilizes the coating steel pipe in outside, basis vertically buried, utilizes the feature that soil layer depths resistance is less.Most importantly this earthing mode flexibility is strong, can with construction path free bend.
Embodiment 2
Be with the difference of embodiment 1, the linear ground structure of a kind of steel pipe pole, welding lead joint 6 on the main muscle 5 of ground connection being included in steel pipe pole column foundation 1, in the both sides of steel pipe pole column foundation, multiple coating steel pipe 4 is set according to same intervals and vertically inserts soil layer, welded together by galvanized steel bar 3 between coating steel pipe 4, be connected on pigtail splice by galvanized steel bar 3, galvanized steel bar 3 is between 1m apart from the distance on ground.Interval 6m between coating steel pipe 4.The length of coating steel pipe 4 is 3m.The interior diameter of coating steel pipe 4 is 7cm.The diameter of galvanized steel bar 3 is 3cm.The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
