Earthing or grounding means 20 after cover plate 222 and after removal sleeve 230 is as shown in Figure 6 and Figure 7.The structure of lid 223 is as shown in Figure 8.
As shown in Fig. 8, Fig. 9 and Figure 10, in the present embodiment, the shape of lid 223 is also similar to that the box-like of one side opening,
Opened up on lid 223 in grooved hole 224, slotted eye 224 and be provided with elastic washer 226.When earthing or grounding means 20 needs external grounding body
When, the round steel or band steel of artificial earthing can be traversed into or out from anti-corrosion elastic washer 226, wherein, round steel or band steel with
Elastic washer 226 is connected for interference fit.In the present embodiment, elastic washer 226 is made up of the material of water-tight corrosion-proof.Cushion
Also there is classification of waterproof (being recommended as 8 grades) higher between circle 226 and slotted eye 224.
Additionally, referring to Fig. 3 and Fig. 5, in the present embodiment, earthing or grounding means 20 also includes water fender 240, water fender 240
It is located on the side wall of covering part 220.Stop that moisture or corrosive substance are penetrated into from the gap between covering part 220 and concrete and connect
In ground device 20.Closer, in the present embodiment, the thickness of water fender 240 from end from covering part 220 to water fender 240
Portion tapers into, i.e. the thickness of water fender 240 is gradually thinning to end from bottom.It is arranged such, it is possible to achieve preferably and wall
Plate is fitted, and then realizes preferably waterproof effect.When earthing or grounding means 20 is installed in wallboard, inner side and the lid of water fender 240
Body is vertical, and when covering part 220 is covered with box body 200, water fender 240 fits in wallboard, prevents liquid from entering earthing or grounding means 20
In.
The Specific construction process that above-mentioned earthing or grounding means 20 is applied in engineering is illustrated below：
As shown in figure 11, before the construction of pipe gallery arrangement of reinforcement completes concrete cast, height is arranged by earthing or grounding means in design
In first connecting portion 212 and wallboard 30 in (note：Now wallboard is not yet poured into a mould) transverse steel 302 be welded to connect, Ran Houjin
Row concrete is poured into a mould.
Covering part 220 when earthing or grounding means dispatches from the factory is cover plate 222, when external grounding body need not be used for, grounding connection
The one end of portion 210 is connected and is cast in concrete with the transverse steel 302 in wallboard 30, and the other end is located at cover plate 222 and box body
In 200 confined spaces for being formed.
When earthing or grounding means is needed for external grounding body, as shown in figure 12, abate cover plate 222 and remove sleeve 230, will
With pre-buried band steel (that is, second connecting portion 214) welding, the other end of grounded round steels 40 after 90 degree of one end bending of grounded round steels 30
The slotted eye 224 of lid is passed through by elastic washer.
As shown in figure 13, lid 223, lid 223 and the interference fit of box body 200, water fender 240 are pushed to the side of box body 200
Wallboard 30 is fitted in, prevents moisture or corrosive substance from being penetrated between lid 223 and concrete gap.
By anticorrosive paints such as all connecting sewing pitchings to lift the integral waterproofing antiseptic effect of earthing or grounding means, after installing
Earthing or grounding means front view it is as shown in figure 14.
Grounding points 210 in above-mentioned earthing or grounding means when needing for external grounding body, simultaneously install by abate cover plate 222
Upper box cover 223, artificial earthing's round steel or band steel are penetrated from the slotted eye 224 of lid 223, due to lid 223 and box body 200 and
External grounding body 40 is interference fit with slotted eye 224, can realize preferable water-tight corrosion-proof effect.Therefore, above-mentioned earthing or grounding means
It is no matter final whether for external grounding body, can realize preferable water-tight corrosion-proof protection so that above-mentioned earthing or grounding means can be fitted
For wet environment and corrosive atmosphere, can provide preferable to grounding points before grounding connection or after grounding connection
Protection, and it is easy to later maintenance, install simple, save manpower.Additionally, the application construction method operation letter of above-mentioned earthing or grounding means
It is single, it is suitable to popularization and application.
