Abstract

The screen (1) has bodies drivable into the earth in a variety of ways. Each body is surrounded by a hollow steel post (6) with loose shoes (3) and a cover (4). A rod (5) in the centre of the body holds the whole assembly together. The surrounding posts are drawn upwards after the bodies (2) have reached the correct depth, leaving them to constitute an elastic protective screen. This absorbs the energy and reduces the amplitudes of vibrations.

Description

457 546 z Elasticiteten av denna skärm åstadkommas genom att de komponenter som utgör skärmen är sinsemellan löst förbundna eller inte förbundna alls. 457 546 z The elasticity of this screen is achieved by the components that make up the screen being loosely connected to each other or not connected at all.

Dämpningen âstadommes genom att materialet som används till uppbyggnaden av skärmen är ett lågdensitetsmaterial. Skärmen består av vertikala eller lutande med varandra inte förbundna skärmelement (2) , som består av i höjdled genom stag (5) löst ihopkopplade kroppar.The attenuation is provided by the fact that the material used for the construction of the screen is a low density material. The screen consists of vertical or inclined screen elements (2) which are not connected to each other, which consist of bodies loosely connected in height by struts (5).

Detta utförande av vibrationsisolering kombinerar en hög vibrationsd ämpande effekt med ett rationellt arbetsförfarande.This embodiment of vibration isolation combines a high vibration damping effect with a rational working procedure.

Föreliggande uppfinning och tillvägagångssätt kännetecknas av vad som framgår av patentkraven, beskrivningar och ritningar.The present invention and method are characterized by what appears from the claims, descriptions and drawings.

Förfaringssättet och anordningen enligt uppfinningen beskrivs på ritningar fig 1-5.The method and the device according to the invention are described in drawings Figs. 1-5.

Fig l redovisar en skärm (1) med pålskor (5) och lock (4).Fig. 1 shows a screen (1) with pole shoes (5) and lid (4).

Fig 2 visar uppbyggnaden av en skärm (1) som består av med varandra inte ihopkopplade skärmelement (2) som i sin tur består av nâgra lätt förbundna kroppar (3) av elastiskt material och försedda med lock (4) och pålskor (5) sammanhållna av stag (6). Den tredje skärmdelen visar en situation, där stålpålen (8) uppdrages, varvid kropparna (3) samtidigt belastas med hjälp av en stålknekt (7). Fig 3-§ visar exempel på alter- nativa placeringsmöjligheter av skärmelement (2) sammanhållna med stång (6) inom skärmen (1).Fig. 2 shows the construction of a screen (1) consisting of interconnected screen elements (2) which in turn consist of some easily connected bodies (3) of elastic material and provided with lids (4) and pole shoes (5) held together of stay (6). The third screen part shows a situation where the steel pile (8) is pulled up, whereby the bodies (3) are simultaneously loaded by means of a steel jack (7). Fig. 3-§ shows examples of alternative placement possibilities of screen elements (2) held together with rods (6) within the screen (1).

I följande beskrivning hänvisas till bifogade ritningar, där fig l visar en skyddsskärm (1) av cellplast längs en järnvägsbank som exempel på vibrationsisolering mot byggnader som befinner sig i närheten av järnvägen och fig 2 visar arbetsmetoden att anbringa en skyddsskärm genom att nedföra kroppar av elastiskt material. Skyddsskärmen i jorden hindrar stötvågens utbredning genom att elastiskt material, t ex cellplast, absorberar vibrationsenergin och minskar svängningsamplituden p g a sin låga densitet. Ett alternativ att föra ned skyddskärmen kan beskrivas enligt följande: Under nedföringsfasen är materialet skyddat genom en ihålig stålpåle (8) som på lämpligt sätt nedtränger i jorden genom slagning, spolning, vibrering, nedpressning eller en kombination därav.In the following description reference is made to the accompanying drawings, in which Fig. 1 shows a protective screen (1) of cellular plastic along a railway bank as an example of vibration insulation against buildings located near the railway and Fig. 2 shows the working method of applying a protective screen by lowering bodies of elastic material. The protective shield in the ground prevents the propagation of the shock wave by elastic material, eg cellular plastic, absorbs the vibrational energy and reduces the amplitude of the oscillation due to its low density. An alternative to lowering the protective screen can be described as follows: During the lowering phase, the material is protected by a hollow steel pile (8) which suitably penetrates into the soil by striking, flushing, vibrating, depressing or a combination thereof.

Pålen (8) består av ett stålplåtshölje med tvärsnitt utformat rektan gulärt, kvadratiskt , rombiskt, runt, ovalt eller i annan passande form samt i vissa fall en lös pålsko (5) som underlättar nedträngning i jord och samtidigt skyddar cellplasten. Innan stâlpålen (8) nedföres fylls pàlen med kroppar av elastiskt material (3) som i huvudsak är format 3 457 546 efter pålens innerkontur. Kroppen kan även uppdelas i lämpligt stora delar som hålls ihop under nedtagningen med en stålstång (6) som går genom kroppens centrum och är förankrad i pålsko (5) och lock (4).The pile (8) consists of a steel plate casing with a cross-section designed rectangular yellow, square, rhombic, round, oval or in another suitable shape and in some cases a loose pile shoe (5) which facilitates penetration into soil and at the same time protects the foam. Before lowering the steel pile (8), the pile is filled with bodies of elastic material (3) which are substantially shaped 3 457 546 according to the inner contour of the pile. The body can also be divided into suitably large parts that are held together during disassembly with a steel bar (6) that goes through the center of the body and is anchored in the pole shoe (5) and lid (4).

Stâlstângen kan ersättas med en lina eller en annan anordning, t ex en nätstrumpa som omsluter kroppen och är förankrad i pålspetsen. Efter nedsänkningen uppdrages den ihåliga stålpålen under samtidig tillfällig belastning av kroppen, t ex med hjälp av en stålknekt (7) som är mindre än pålens innermått, så att kroppen stannar kvar i sitt nedsänkta läge tills de kringliggande jordmassorna tränger fram nnt de under uppdragningen redan frilagda delarna av kropparna och häller dessa kvar på sin plats.The steel bar can be replaced with a rope or other device, such as a net sock that encloses the body and is anchored in the pole tip. After immersion, the hollow steel pile is pulled up under simultaneous temporary loading of the body, for example by means of a steel jack (7) which is smaller than the inner dimensions of the pile, so that the body remains in its lowered position until the surrounding soil masses penetrate. exposed the parts of the bodies and pours them into place.

I ett alternativ av uppfinningen kan stålpâlen fyllas med kroppar, sedan pålen har nedforts helt eller delvis.In an alternative of the invention, the steel pile can be filled with bodies, after the pile has been lowered in whole or in part.

Placering av skärmelemcnt (2) enligt uppfinningen kan ske på många sätt och fig 3, 4 och 5 visar några exempel.Placement of the screen element (2) according to the invention can take place in many ways and Figs. 3, 4 and 5 show some examples.

En skydds karm av t ex cellplast kräver inga underhållsarbeten, har lång livstid, kan tillverkas för ett billigt m2-pris, och dessutom utgör skärmen inget hinder för framtida markarbeten, t ex tryckning av rörledningar under järnvägsbanken.A protective frame made of, for example, cellular plastic requires no maintenance work, has a long service life, can be manufactured for a cheap m2 price, and in addition the screen does not constitute an obstacle to future ground work, eg printing of pipelines under the railway bank.
