Description
Technical field
The utility model relates to transformer station's pile tube technical field, specifically a kind of transformer station's pile tube with long vertical grounding electrode.
Background technology
Should basic farmland be dodged when current substation location is selected, take mountain region, wasteland etc. as far as possible.Particularly coastal and riparian area, transformer station can be arranged on the weak soils such as muddy ground usually, and for weak soil geological conditions, transformer station's basement process then adopts pile tube scheme.Simultaneously due to the expansion of power system capacity, the densification of transformer station's layout, the transformer station that part site place soil resistivity is high needs to arrange some long vertical grounding electrodes to reduce substation grounding resistance, the diffusing ability of enhanced grounding net usually.Usual power transformation head of a station vertical grounding electrode is independent construction, and adopt angle steel or round steel to make it enter in soil by external force impact, the general degree of depth is at about 2.5m; Or after getting out special deep hole by rig, long vertical grounding electrode is buried underground in the borehole.All there is the problem that operating expenses is higher, construction period is longer in these two kinds of forms of construction work.Though have, the patent No. is 200410066704.5, name is called that the file of aluminum alloy grounding pipe pile relates to the application of Special grounding pile tube, but this technical scheme cannot realize in actual life, its piling process must be damaged ground connection and bury rod, even if do not damage ground connection to bury rod, also need excavation in addition to place ground connection and bury rod, and this technology is exclusively used in ground connection use, there is the problem that long vertical grounding electrode needs construction separately equally.How to develop a kind of technical scheme that long vertical grounding electrode can be avoided to construct separately and become the technical problem being badly in need of solving.
Utility model content
The purpose of this utility model needs the defect of construction separately to solve long vertical grounding electrode in prior art, provides a kind of transformer station's pile tube with long vertical grounding electrode to solve the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of transformer station's pile tube with long vertical grounding electrode, comprise pile for prestressed pipe, the upper end of described pile for prestressed pipe is provided with a closedtop and closes steel ring, the lower end of pile for prestressed pipe is provided with a underseal and closes steel ring, also comprise ground connection band iron, described ground connection band iron is arranged on the pile lining of pile for prestressed pipe by anchor ear, and the two ends of ground connection band iron are closed steel ring and stake underseal respectively and closed steel ring and weld with stake closedtop, ground connection band iron is positioned at one end that a closedtop closes steel ring and is welded with ground lead.
Also comprise horizontal grounding objects in cushion cap bed course, pile foundation support table and station, the stake closedtop that described cushion cap bed course is arranged on pile for prestressed pipe closes steel ring one end, is provided with pile foundation support table above cushion cap bed course, and described ground lead is connected with horizontal grounding objects in station.
beneficial effect
A kind of transformer station's pile tube with long vertical grounding electrode of the present utility model, compared with prior art combines long vertical grounding electrode construction with pile tube operation, avoids the independent construction for long vertical grounding electrode.By pile driver, pile tube is together squeezed in soil together with long vertical grounding electrode, save traditional long vertical grounding electrode boring and the workload of backfill, reduce construction costs, reduce field operation workload, there is good technology and economic benefit.

Wherein, 1-pile for prestressed pipe, 2-pile foundation support table, 3-cushion cap bed course, 4-ground connection band iron, 5-anchor ear, 6-stake closedtop closes steel ring, 7-stake underseal closes steel ring, 8-ground lead, 9-station in horizontal grounding objects.
Detailed description of the invention
For making to have a better understanding and awareness architectural feature of the present utility model and effect of reaching, coordinating detailed description in order to preferred embodiment and accompanying drawing, being described as follows:
As shown in Figure 1, a kind of transformer station's pile tube with long vertical grounding electrode described in the utility model, comprise pile for prestressed pipe 1, the upper end of pile for prestressed pipe 1 is provided with a closedtop and closes steel ring 6, the lower end of pile for prestressed pipe 1 is provided with a underseal and closes steel ring 7, pile for prestressed pipe 1 is squeezed in soil by pile driver in the prior art, carries out the construction of transformer station.Ground connection band iron 4 is arranged on the pile lining of pile for prestressed pipe 1 by anchor ear 5, ground connection band iron 4 is attached to outside the pile lining of pile for prestressed pipe 1, is fixed on pile for prestressed pipe 1, in order to ensure fixed effect by anchor ear 5, anchor ear 5 can use 2, plays the fixing of ground connection band iron 4 and pile for prestressed pipe 1.The two ends of ground connection band iron 4 are closed steel ring 6 and stake underseal respectively and are closed steel ring 7 and weld with stake closedtop, one end and the stake closedtop of ground connection band iron 4 close steel ring 6 and weld, and the other end and the stake underseal of ground connection band iron 4 close steel ring 7 and weld, thus as a whole with pile for prestressed pipe 1 one-tenth.Because ground connection band iron 4 is attached on pile for prestressed pipe 1, contact with the steel ring at pile for prestressed pipe 1 two ends, the now combination of ground connection band iron 4 and pile for prestressed pipe 1 is then equivalent to long vertical grounding electrode.Ground connection band iron 4 is positioned at one end that a closedtop closes steel ring 6 and is welded with ground lead 8, ground connection band iron 4 draws ground lead 8 from the upper end of pile for prestressed pipe 1, needs for substation grounding.
As shown in Figure 2, when reality uses, use pile driver directly to squeeze in soil by pile tube, also drive ground connection band iron 4 to squeeze in soil simultaneously, make ground connection band iron 4 fully ground connection.Part of basseting on pile for prestressed pipe 1 top builds cushion cap bed course 3 again, builds pile foundation support table 2 again, need for construction of transformer substation on cushion cap bed course 3 top.After construction of transformer substation terminates, when needing to carry out long vertical grounding electrode, then by horizontal grounding objects 9(horizontal grounding net in the station of transformer station) be directly connected with ground lead 8, fully imbed in ground because ground lead 8 is connected to the band iron 4 entered in soil, therefore reach the object reducing substation grounding resistance, directly serve the effect of long vertical grounding electrode.By the construction utilizing the work progress of the conventional pile tube of transformer station can solve power transformation head of a station vertical grounding electrode device, save the independent construction link of the required boring of traditional long vertical grounding electrode construction, accelerate speed of application.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and manual; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
