Description

Oppfinnelsen vedrorer en jordelektrode omfattende f.eks en stav eller et ror, for i det vesentlige vertikal inndrivning i grunnen, hvorunder det utoves en kraft på staven eller roret i dennes eller dettes lengderetning. The invention relates to an earth electrode comprising, for example, a rod or a rudder, for essentially vertical penetration into the ground, during which a force is exerted on the rod or the rudder in its or its longitudinal direction.

Ved inndrivning av stavformede jordelektroder i grunnen oppstår When driving rod-shaped earth electrodes into the ground occurs

det problem at den i grunnen inntrengende stavende moter så mye the problem that the basically intrusive spelling fashions so much

motstand at store krefter må utoves. Dessuten krever inndrivningen av en jordelektrode i grunnen meget tid. For tilveie-bringelse av de nodvendige krefter benytter man ofte såkalte ram-bukker ved hvilke det i elektrodens lengderetning utoves krefter. Ved jordsjikt som yder særlig stor motstand, oppstår videre den fare at elektroden under inndrivning i grunnen avviker fra den vertikale stilling, hvilket ofte er tilfelle når élektroden består av et antall stavdeler som er koblet til hverandre i de respektive ender. Dessuten inntrer det ofte at elektroden knek-ker, hvilket forer til at elektroden helt eller delvis ikke mer tjener sitt formål. Dessuten blir det på forbindelsesstedet mellom elektrode-stavdelene utovet et stort trykk, hvilket ved inndrivning av en elektrode i en stenet grunn kan fore til brudd i disse forbindelsesdeler. resistance that great forces must be exerted. In addition, driving an earth electrode into the ground requires a lot of time. To provide the necessary forces, so-called ram frames are often used, in which forces are added in the lengthwise direction of the electrode. In the case of a layer of soil that offers particularly high resistance, there is also the danger that the electrode deviates from the vertical position during penetration into the ground, which is often the case when the electrode consists of a number of rod parts which are connected to each other at the respective ends. In addition, it often happens that the electrode breaks, which leads to the electrode completely or partially no longer serving its purpose. In addition, at the connection point between the electrode-rod parts, a large pressure is exerted, which, when an electrode is driven into a stony ground, can lead to breakage in these connection parts.

Man har forsokt å unngå disse ovennevnte ulemper ved å forsyne den i grunnen inntrengende ende av staven med en spiss. Dette er imidlertid ikke tilstrekkelig. Attempts have been made to avoid these above-mentioned disadvantages by providing the basically penetrating end of the rod with a point. However, this is not sufficient.

Ifolge oppfinnelsen unngås disse ulemper ved at den ende av staven som skal drives inn i grunnen, forsynes med et fritt roterbart spiss-stykke med skjæreflater og med skovlformede partier som bevirker at spiss-stykket roterer om sin akse under inntreng-ning i grunnen. According to the invention, these disadvantages are avoided by providing the end of the rod which is to be driven into the ground with a freely rotatable tip piece with cutting surfaces and with shovel-shaped parts which cause the tip piece to rotate about its axis during penetration into the ground.

På denne måte borer jordelektroden seg en vei gjennom grunnen. Dette oppnåes ved de krefter, som genereres av for eksempel en rambukk og utoves på elektroden i dennes lengderetning, bevirker at spiss-stykket utforer en rotasjon som en folge av de mot-standskrefter som utoves av jordsjiktene på skovlflåtene. Spiss-stykket utgjores fortrinnsvis av et koggerformet legeme i hvis lukkede ende det er anordnet skjæreflater eller skovlformede partier. I det koggerformede legemes åpne ende kan elektrodestaven være lost anordnet, dvs. fritt dreibart relativt spiss-stykket, f.eks. som en hann-hunnkobling. In this way, the earth electrode drills its way through the ground. This is achieved by the forces, which are generated by, for example, a ram and applied to the electrode in its longitudinal direction, causing the tip piece to perform a rotation as a result of the resistance forces applied by the soil layers on the paddle floats. The tip piece is preferably made of a quiver-shaped body at the closed end of which cutting surfaces or blade-shaped parts are arranged. At the open end of the quiver-shaped body, the electrode rod can be loosely arranged, i.e. freely rotatable relative to the tip piece, e.g. as a male-female coupling.

Istedenfor et spesielt spiss-stykke kan enden av elektrodestaven også være forsynt med skjæreflater og skovlformede partier, hvor- ved staven da må være fritt dreibart relativt rambukken, eller hvis elektroden består av flere deler, relativt nestfolgende del. Instead of a special pointed piece, the end of the electrode rod can also be provided with cutting surfaces and shovel-shaped parts, whereby the rod must then be freely rotatable relative to the frame, or if the electrode consists of several parts, relative to the next part.

Oppfinnelsen skal nærmere beskrives nedenfor ved hjelp av to ut-forelseseksempler under henvisning til tegningene, hvorpå Fig. 1 viser et snitt gjennom et spiss-stykke ifolge oppfinnelsen, The invention will be described in more detail below with the help of two embodiment examples with reference to the drawings, on which Fig. 1 shows a section through a tip piece according to the invention,

Fig. 2 viser spiss-stykket ifolge fig. 1 sett nedenfra, Fig. 2 shows the tip piece according to fig. 1 seen from below,

Fig. 3 viser et spiss-stykke ifolge fig.l, i hvilket det er fritt roterbart anordnet en jordelektrode med beskyttelsesmantel, Fig. 3a viser et spiss-stykke ifolge fig. 1 i hvilket det er fritt roterbart en jordelektrode uten beskyttelsesmantel, og Fig. 4 viser en jordelektrode hvis endedel er forsynt med skjæreflater eller skovlflater. Fig. 3 shows a tip piece according to fig. 1, in which an earth electrode with protective sheath is freely rotatable, Fig. 3a shows a tip piece according to fig. 1 in which an earth electrode without a protective sheath is freely rotatable, and Fig. 4 shows an earth electrode whose end part is provided with cutting surfaces or blade surfaces.

Spiss-stykket omfatter et koggerformet legeme 2 i hvis åpning 3 The tip piece comprises a quiver-shaped body 2 in whose opening 3

det kan innfores en stav. I den lukkede ende er det anordnet skjæreflater 4,5 som går over i skovlflater 6,7,8 og 9. I dette utforelseseksempel oppviser spiss-stykket 2 to skjæreflater 5 og 4 som ligger i to innbyrdes forskjovne plan som forloper loddrett på spiss-stykkets lengdeakse. Boringen i spiss-stykket 1 har en flat endeflate slik at jordelektroden ved inndrivningen ikke fast-kiles. Dessuten er den andre ende av jordelektroden lo,lo' også a staff can be introduced. At the closed end, there are arranged cutting surfaces 4,5 which merge into blade surfaces 6,7,8 and 9. In this exemplary embodiment, the tip piece 2 has two cutting surfaces 5 and 4 which lie in two mutually offset planes that run vertically on the tip the longitudinal axis of the piece. The bore in the tip piece 1 has a flat end surface so that the earth electrode is not wedged when driven in. Also, the other end of the ground electrode is lo,lo' as well

i en viss grad avskrådd slik at en"eventuell dannelse av grader ikke har innflytelse. Ved jordelektroden 11 ifolge fig. 4 er ende-delen utformet med skjæreflater og skovlflater som tjener det to a certain extent chamfered so that a possible formation of burrs has no influence. At the ground electrode 11, according to Fig. 4, the end part is designed with cutting surfaces and blade surfaces that serve

samme formål som flatene på spiss-stykket ifolge fig. 1. same purpose as the surfaces on the tip piece according to fig. 1.

Ved forsok hvor en jordelektrode med spiss-stykket ifolge oppfinnelsen ble drevet ned i grunnen viste det seg at den herfor nodvendige tid utgjorde omtrent 1/3 av den tid som ville være nodvendige for å drive en spissformet jordelektrode av"hittil kjente typer. In an experiment where an earth electrode with the pointed piece according to the invention was driven into the ground, it turned out that the time required for this was about 1/3 of the time that would be required to drive a pointed earth electrode of the previously known types.
